Upgrading to new React Native versions

Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you.

Expo projects

Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

Projects built with native code

Because React Native projects built with native code are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

React Native projects

+

Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

Upgrade based on Git

-

The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

-
    -
  • First, it computes a Git patch between both old and new template files,
    • -
  • Then, the patch is applied on the user's sources.
    • -
+

The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

+

1. Make sure your project uses Git

-

IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

+

This step applies only to projects that don't use Git. Skip it if yours use it.

-

1. Install Git

-

While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

-

2. Install the react-native-git-upgrade module

-

The react-native-git-upgrade module provides a CLI and must be installed globally:

-
$ npm install -g react-native-git-upgrade
+
While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:

+
git init
+git add .
+git commit -m "upgrade RN"
 

-
3. Run the command

+
After the upgrade is done and conflicts resolved, you can remove the .git directory.

+
2. Run the upgrade command

 
Run the following command to start the process of upgrading to the latest version:

-
$ react-native-git-upgrade
+
react-native upgrade
 

-

-
You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z

-

-
Upon completion, run the following command to find your corresponding git patch file.

-
$ ls $TMPDIR/react-native-git-upgrade
+
You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:

+
react-native upgrade 0.59.0-rc.0
 

-
To apply the git patch, run git apply <path to patch> inside your project folder.

-
The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.

+
The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.

 
4. Resolve the conflicts

 
Conflicted files include delimiters which make very clear where the changes come from. For example:

3. Configure app to use static bundle

-
During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.

-
In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

-
#ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-

-
This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.

-

-
Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:

-

-
 if [ "${CONFIGURATION}" == "Debug" ]; then
-  export SKIP_BUNDLING=true
- fi
-

As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.

 
  // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"

Generating Signed APK

Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

Generating a signing key

You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

-
$ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
$ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 

 
This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.

 
The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Let's do this thing.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Let's do this thing.

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z

    Upgrading to new React Native versions

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you. The instructions are a bit different depending on whether you used create-react-native-app or react-native init to create your project.

    Upgrading to new React Native versions

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Automated End-to-End Tests

    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.

Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Automated End-to-End Tests
    
+
    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.
    
+
    You can run Detox end-to-end tests locally by installing the Detox CLI on macOS, then running the following in the command line:
    
+
    $ cd react-native
+$ npm run build-ios-e2e
+$ npm run test-ios-e2e
+
    
+
    If you work on a component or API that isn't convered by a Detox test, please consider adding one. Detox tests are stored under RNTester/e2e/__tests__.
    
 
    Apple TV
    
 
    The same tests discussed above for iOS will also run on tvOS. In the RNTester Xcode project, select the RNTester-tvOS target, and you can follow the same steps above to run the tests in Xcode.
    
 
    You can run Apple TV unit and integration tests locally by running the following in the command line on macOS:
    
 
    $ cd react-native
 $ ./scripts/objc-test-tvos.sh (make sure the line `TEST="test"` is uncommented)

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-

    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];

    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.
    
 
    
 
    You can also use the React Native CLI to perform this operation using the option --configuration with the value Release (e.g. react-native run-ios --configuration Release).

    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-
    
-
     if [ "${CONFIGURATION}" == "Debug" ]; then
-  export SKIP_BUNDLING=true
- fi

    Pro Tips
    
 
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
   launchScreenView.frame = self.window.bounds;
   rootView.loadingView = launchScreenView;

    3. Build app for release
    
 
    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.
    
 
    
 
    You can also use the React Native CLI to perform this operation using the option --configuration with the value Release (e.g. react-native run-ios --configuration Release).

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Upgrading to new React Native versions

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.

    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-

    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Let's do this thing.

    Hello World

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Let's do this thing.

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application.

-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.

    Upgrading to new React Native versions

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you. The instructions are a bit different depending on whether you used create-react-native-app or react-native init to create your project.

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts

    3. Configure app to use static bundle

    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.

    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];

-#endif

    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Automated End-to-End Tests

    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.

+$ npm run build-ios-e2e
+$ npm run test-ios-e2e

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Automated End-to-End Tests
    
+
    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.
    
+
    You can run Detox end-to-end tests locally by installing the Detox CLI on macOS, then running the following in the command line:
    
+
    $ cd react-native
+$ npm run build-ios-e2e
+$ npm run test-ios-e2e

    If you work on a component or API that isn't convered by a Detox test, please consider adding one. Detox tests are stored under RNTester/e2e/__tests__.

    The same tests discussed above for iOS will also run on tvOS. In the RNTester Xcode project, select the RNTester-tvOS target, and you can follow the same steps above to run the tests in Xcode.
    
 
    You can run Apple TV unit and integration tests locally by running the following in the command line on macOS:

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-
    
-

    Pro Tips
    
 
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];

    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.
    
 
    
 
    You can also use the React Native CLI to perform this operation using the option --configuration with the value Release (e.g. react-native run-ios --configuration Release).

Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-
    
-
     if [ "${CONFIGURATION}" == "Debug" ]; then
-  export SKIP_BUNDLING=true
- fi
-

    Pro Tips
    
 
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
   launchScreenView.frame = self.window.bounds;
   rootView.loadingView = launchScreenView;

+
    3. Build app for release
    
 
    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.
    
 
    
 
    You can also use the React Native CLI to perform this operation using the option --configuration with the value Release (e.g. react-native run-ios --configuration Release).

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props.

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    Assign this property to a custom function which will be called when someone performs the "magic tap" gesture, which is a double-tap with two fingers. A magic tap function should perform the most relevant action a user could take on a component. In the Phone app on iPhone, a magic tap answers a phone call, or ends the current one.

    Assign this property to a custom function which will be called when someone performs the "escape" gesture, which is a two finger Z shaped gesture. An escape function should move back hierarchically in the user interface. This can mean moving up or back in a navigation hierarchy or dismissing a modal user interface.

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-

    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Upgrading to new React Native versions

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you. The instructions are a bit different depending on whether you used create-react-native-app or react-native init to create your project.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-

    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Let's do this thing.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props.

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    Assign this property to a custom function which will be called when someone performs the "escape" gesture, which is a two finger Z shaped gesture. An escape function should move back hierarchically in the user interface. This can mean moving up or back in a navigation hierarchy or dismissing a modal user interface. If the selected element does not have an onAccessibilityEscape function, the system will attempt to traverse up the view hierarchy until it finds a view that does or bonk to indicate it was unable to find one.
    
 
    accessibilityComponentType (Android)
    
 
    
 
    Note: > accessibilityComponentType will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.

    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];

-#endif

-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade.

    Upgrading to new React Native versions

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you. The instructions are a bit different depending on whether you used create-react-native-app or react-native init to create your project.

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade

    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.

    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts

    During the development process, React Native has loaded your JavaScript code dynamically at runtime.

Doing this requires a code change in your code so that it knows to load the static bundle.

    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Automated End-to-End Tests

    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Automated End-to-End Tests
    
+
    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.
    
+
    You can run Detox end-to-end tests locally by installing the Detox CLI on macOS, then running the following in the command line:
    
+
    $ cd react-native
+$ npm run build-ios-e2e
+$ npm run test-ios-e2e
+
    
+
    If you work on a component or API that isn't convered by a Detox test, please consider adding one. Detox tests are stored under RNTester/e2e/__tests__.
    
 
    Apple TV
    
 
    The same tests discussed above for iOS will also run on tvOS. In the RNTester Xcode project, select the RNTester-tvOS target, and you can follow the same steps above to run the tests in Xcode.
    
 
    You can run Apple TV unit and integration tests locally by running the following in the command line on macOS:

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-
    
-
     if [ "${CONFIGURATION}" == "Debug" ]; then
-  export SKIP_BUNDLING=true
- fi

    Pro Tips
    
 
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
   launchScreenView.frame = self.window.bounds;
   rootView.loadingView = launchScreenView;

    3. Build app for release
    
 
    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-
    
-
     if [ "${CONFIGURATION}" == "Debug" ]; then
-  export SKIP_BUNDLING=true
- fi
-

    Pro Tips
    
 
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
   launchScreenView.frame = self.window.bounds;
   rootView.loadingView = launchScreenView;

    3. Build app for release
    
 
    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.
    
 
    
 
    You can also use the React Native CLI to perform this operation using the option --configuration with the value Release (e.g. react-native run-ios --configuration Release).

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props.

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.

    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

-#endif

    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.

    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    3. Configure app to use static bundle

    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.

    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];

-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-

    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Let's do this thing.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props.

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

An escape function should move back hierarchically in the user interface. This can mean moving up or back in a navigation hierarchy or dismissing a modal user interface. If the selected element does not have an onAccessibilityEscape function, the system will attempt to traverse up the view hierarchy until it finds a view that does or bonk to indicate it was unable to find one.

-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:

-
    $ ls $TMPDIR/react-native-git-upgrade

    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.

    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts

    Upgrading to new React Native versions

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you. The instructions are a bit different depending on whether you used create-react-native-app or react-native init to create your project.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade

-

    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z

-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade

    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Automated End-to-End Tests

    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Automated End-to-End Tests
    
+
    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.
    
+
    You can run Detox end-to-end tests locally by installing the Detox CLI on macOS, then running the following in the command line:
    
+
    $ cd react-native
+$ npm run build-ios-e2e
+$ npm run test-ios-e2e
+
    
+
    If you work on a component or API that isn't convered by a Detox test, please consider adding one. Detox tests are stored under RNTester/e2e/__tests__.
    
 
    Apple TV
    
 
    The same tests discussed above for iOS will also run on tvOS. In the RNTester Xcode project, select the RNTester-tvOS target, and you can follow the same steps above to run the tests in Xcode.
    
 
    You can run Apple TV unit and integration tests locally by running the following in the command line on macOS:

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-
    
-
     if [ "${CONFIGURATION}" == "Debug" ]; then
-  export SKIP_BUNDLING=true
- fi

    Pro Tips
    
 
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
   launchScreenView.frame = self.window.bounds;
   rootView.loadingView = launchScreenView;

+
    
+

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-
    
-
     if [ "${CONFIGURATION}" == "Debug" ]; then
-  export SKIP_BUNDLING=true
- fi
-

    Pro Tips
    
 
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
   launchScreenView.frame = self.window.bounds;
   rootView.loadingView = launchScreenView;

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    Native App Accessibility (iOS and Android)
    
+
    Both iOS and Android provide APIs for making apps accessible to people with disabilities. In addition, both platforms provide bundled assistive technologies, like the screen readers VoiceOver (iOS) and TalkBack (Android) for the visually impaired. Similarly, in React Native we have included APIs designed to provide developers with support for making apps more accessible. Take note, iOS and Android differ slightly in their approaches, and thus the React Native implementations may vary by platform.
    
+
    In addition to this documentation, you might find this blog post about React Native accessibility to be useful.
    
+
    Making Apps Accessible
    
+
    Accessibility properties
    
+
    accessible (iOS, Android)
    
+
    When true, indicates that the view is an accessibility element. When a view is an accessibility element, it groups its children into a single selectable component. By default, all touchable elements are accessible.
    
+
    On Android, accessible={true} property for a react-native View will be translated into native focusable={true}.
    
+
    <View accessible={true}>
+  <Text>text one</Text>
+  <Text>text two</Text>
+</View>
+
    
+
    In the above example, we can't get accessibility focus separately on 'text one' and 'text two'. Instead we get focus on a parent view with 'accessible' property.
    
+
    accessibilityLabel (iOS, Android)
    
+
    When a view is marked as accessible, it is a good practice to set an accessibilityLabel on the view, so that people who use VoiceOver know what element they have selected. VoiceOver will read this string when a user selects the associated element.
    
+
    To use, set the accessibilityLabel property to a custom string on your View, Text or Touchable:
    
+
    <TouchableOpacity
+  accessible={true}
+  accessibilityLabel="Tap me!"
+  onPress={this._onPress}>
+  <View style={styles.button}>
+    <Text style={styles.buttonText}>Press me!</Text>
+  </View>
+</TouchableOpacity>
+
    
+
    In the above example, the accessibilityLabel on the TouchableOpacity element would default to "Press me!". The label is constructed by concatenating all Text node children separated by spaces.
    
+
    accessibilityHint (iOS, Android)
    
+
    An accessibility hint helps users understand what will happen when they perform an action on the accessibility element when that result is not obvious from the accessibility label.
    
+
    To use, set the accessibilityHint property to a custom string on your View, Text or Touchable:
    
+
    <TouchableOpacity
+  accessible={true}
+  accessibilityLabel="Go back"
+  accessibilityHint="Navigates to the previous screen"
+  onPress={this._onPress}>
+  <View style={styles.button}>
+    <Text style={styles.buttonText}>Back</Text>
+  </View>
+</TouchableOpacity>
+
    
+
    iOS In the above example, VoiceOver will read the hint after the label, if the user has hints enabled in the device's VoiceOver settings. Read more about guidelines for accessibilityHint in the iOS Developer Docs
    
+
    Android In the above example, Talkback will read the hint after the label. At this time, hints cannot be turned off on Android.
    
+
    accessibilityIgnoresInvertColors(iOS)
    
+
    Inverting screen colors is an Accessibility feature that makes the iPhone and iPad easier on the eyes for some people with a sensitivity to brightness, easier to distinguish for some people with color blindness, and easier to make out for some people with low vision. However, sometimes you have views such as photos that you don't want to be inverted. In this case, you can set this property to be false so that these specific views won't have their colors inverted.
    
+
    accessibilityRole (iOS, Android)
    
+
    
+
    Note: Accessibility Role and Accessibility States are meant to be a cross-platform solution to replace accessibilityTraits and accessibilityComponentType, which will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    
+
    Accessibility Role tells a person using either VoiceOver on iOS or TalkBack on Android the type of element that is focused on. To use, set the accessibilityRole property to one of the following strings:
    
+
      
+
    • none Used when the element has no role.
      • 
+
    • button Used when the element should be treated as a button.
      • 
+
    • link Used when the element should be treated as a link.
      • 
+
    • search Used when the text field element should also be treated as a search field.
      • 
+
    • image Used when the element should be treated as an image. Can be combined with button or link, for example.
      • 
+
    • keyboardkey Used when the element acts as a keyboard key.
      • 
+
    • text Used when the element should be treated as static text that cannot change.
      • 
+
    • adjustable Used when an element can be "adjusted" (e.g. a slider).
      • 
+
    • imagebutton Used when the element should be treated as a button and is also an image.
      • 
+
    • header Used when an element acts as a header for a content section (e.g. the title of a navigation bar).
      • 
+
    • summary Used when an element can be used to provide a quick summary of current conditions in the app when the app first launches.
      • 
+
    
+
    accessibilityStates (iOS, Android)
    
+
    
+
    Note: > accessibilityRole and accessibilityStates are meant to be a cross-platform solution to replace accessibilityTraits and accessibilityComponentType, which will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    
+
    Accessibility State tells a person using either VoiceOver on iOS or TalkBack on Android the state of the element currently focused on. The state of the element can be set either to selected or disabled or both:
    
+
      
+
    • selected Used when the element is in a selected state. For example, a button is selected.
      • 
+
    • disabled Used when the element is disabled and cannot be interacted with.
      • 
+
    
+
    To use, set the accessibilityStates to an array containing either selected, disabled, or both.
    
+
    accessibilityTraits (iOS)
    
+
    
+
    Note: accessibilityTraits will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    
+
    Accessibility traits tell a person using VoiceOver what kind of element they have selected. Is this element a label? A button? A header? These questions are answered by accessibilityTraits.
    
+
    To use, set the accessibilityTraits property to one of (or an array of) accessibility trait strings:
    
+
      
+
    • none Used when the element has no traits.
      • 
+
    • button Used when the element should be treated as a button.
      • 
+
    • link Used when the element should be treated as a link.
      • 
+
    • header Used when an element acts as a header for a content section (e.g. the title of a navigation bar).
      • 
+
    • search Used when the text field element should also be treated as a search field.
      • 
+
    • image Used when the element should be treated as an image. Can be combined with button or link, for example.
      • 
+
    • selected Used when the element is selected. For example, a selected row in a table or a selected button within a segmented control.
      • 
+
    • plays Used when the element plays its own sound when activated.
      • 
+
    • key Used when the element acts as a keyboard key.
      • 
+
    • text Used when the element should be treated as static text that cannot change.
      • 
+
    • summary Used when an element can be used to provide a quick summary of current conditions in the app when the app first launches. For example, when Weather first launches, the element with today's weather conditions is marked with this trait.
      • 
+
    • disabled Used when the control is not enabled and does not respond to user input.
      • 
+
    • frequentUpdates Used when the element frequently updates its label or value, but too often to send notifications. Allows an accessibility client to poll for changes. A stopwatch would be an example.
      • 
+
    • startsMedia Used when activating an element starts a media session (e.g. playing a movie, recording audio) that should not be interrupted by output from an assistive technology, like VoiceOver.
      • 
+
    • adjustable Used when an element can be "adjusted" (e.g. a slider).
      • 
+
    • allowsDirectInteraction Used when an element allows direct touch interaction for VoiceOver users (for example, a view representing a piano keyboard).
      • 
+
    • pageTurn Informs VoiceOver that it should scroll to the next page when it finishes reading the contents of the element.
      • 
+
    
+
    accessibilityViewIsModal (iOS)
    
+
    A Boolean value indicating whether VoiceOver should ignore the elements within views that are siblings of the receiver.
    
+
    For example, in a window that contains sibling views A and B, setting accessibilityViewIsModal to true on view B causes VoiceOver to ignore the elements in the view A. On the other hand, if view B contains a child view C and you set accessibilityViewIsModal to true on view C, VoiceOver does not ignore the elements in view A.
    
+
    accessibilityElementsHidden (iOS)
    
+
    A Boolean value indicating whether the accessibility elements contained within this accessibility element are hidden.
    
+
    For example, in a window that contains sibling views A and B, setting accessibilityElementsHidden to true on view B causes VoiceOver to ignore the elements in the view B. This is similar to the Android property importantForAccessibility="no-hide-descendants".
    
+
    onAccessibilityTap (iOS)
    
+
    Use this property to assign a custom function to be called when someone activates an accessible element by double tapping on it while it's selected.
    
+
    onMagicTap (iOS)
    
+
    Assign this property to a custom function which will be called when someone performs the "magic tap" gesture, which is a double-tap with two fingers. A magic tap function should perform the most relevant action a user could take on a component. In the Phone app on iPhone, a magic tap answers a phone call, or ends the current one. If the selected element does not have an onMagicTap function, the system will traverse up the view hierarchy until it finds a view that does.
    
+
    onAccessibilityEscape (iOS)
    
+
    Assign this property to a custom function which will be called when someone performs the "escape" gesture, which is a two finger Z shaped gesture. An escape function should move back hierarchically in the user interface. This can mean moving up or back in a navigation hierarchy or dismissing a modal user interface. If the selected element does not have an onAccessibilityEscape function, the system will attempt to traverse up the view hierarchy until it finds a view that does or bonk to indicate it was unable to find one.
    
+
    accessibilityComponentType (Android)
    
+
    
+
    Note: > accessibilityComponentType will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    
+
    In some cases, we also want to alert the end user of the type of selected component (i.e., that it is a “button”). If we were using native buttons, this would work automatically. Since we are using javascript, we need to provide a bit more context for TalkBack. To do so, you must specify the ‘accessibilityComponentType’ property for any UI component. We support 'none', ‘button’, ‘radiobutton_checked’ and ‘radiobutton_unchecked’.
    
+
    <TouchableWithoutFeedback accessibilityComponentType=”button”
+  onPress={this._onPress}>
+  <View style={styles.button}>
+    <Text style={styles.buttonText}>Press me!</Text>
+  </View>
+</TouchableWithoutFeedback>
+
    
+
    In the above example, the TouchableWithoutFeedback is being announced by TalkBack as a native Button.
    
+
    accessibilityLiveRegion (Android)
    
+
    When components dynamically change, we want TalkBack to alert the end user. This is made possible by the ‘accessibilityLiveRegion’ property. It can be set to ‘none’, ‘polite’ and ‘assertive’:
    
+
      
+
    • none Accessibility services should not announce changes to this view.
      • 
+
    • polite Accessibility services should announce changes to this view.
      • 
+
    • assertive Accessibility services should interrupt ongoing speech to immediately announce changes to this view.
      • 
+
    
+
    <TouchableWithoutFeedback onPress={this._addOne}>
+  <View style={styles.embedded}>
+    <Text>Click me</Text>
+  </View>
+</TouchableWithoutFeedback>
+<Text accessibilityLiveRegion="polite">
+  Clicked {this.state.count} times
+</Text>
+
    
+
    In the above example method _addOne changes the state.count variable. As soon as an end user clicks the TouchableWithoutFeedback, TalkBack reads text in the Text view because of its 'accessibilityLiveRegion=”polite”' property.
    
+
    importantForAccessibility (Android)
    
+
    In the case of two overlapping UI components with the same parent, default accessibility focus can have unpredictable behavior. The ‘importantForAccessibility’ property will resolve this by controlling if a view fires accessibility events and if it is reported to accessibility services. It can be set to ‘auto’, ‘yes’, ‘no’ and ‘no-hide-descendants’ (the last value will force accessibility services to ignore the component and all of its children).
    
+
    <View style={styles.container}>
+  <View style={{position: 'absolute', left: 10, top: 10, right: 10, height: 100,
+    backgroundColor: 'green'}} importantForAccessibility=”yes”>
+    <Text> First layout </Text>
+  </View>
+  <View style={{position: 'absolute', left: 10, top: 10, right: 10, height: 100,
+    backgroundColor: 'yellow'}} importantForAccessibility=”no-hide-descendants”>
+    <Text> Second layout </Text>
+  </View>
+</View>
+
    
+
    In the above example, the yellow layout and its descendants are completely invisible to TalkBack and all other accessibility services. So we can easily use overlapping views with the same parent without confusing TalkBack.
    
+
    Checking if a Screen Reader is Enabled
    
+
    The AccessibilityInfo API allows you to determine whether or not a screen reader is currently active. See the AccessibilityInfo documentation for details.
    
+
    Sending Accessibility Events (Android)
    
+
    Sometimes it is useful to trigger an accessibility event on a UI component (i.e. when a custom view appears on a screen or a custom radio button has been selected). Native UIManager module exposes a method ‘sendAccessibilityEvent’ for this purpose. It takes two arguments: view tag and a type of an event.
    
+
    import { UIManager, findNodeHandle } from 'react-native';
+
+_onPress: function() {
+  const radioButton = this.state.radioButton === 'radiobutton_checked' ?
+    'radiobutton_unchecked' : 'radiobutton_checked'
+
+  this.setState({
+    radioButton: radioButton
+  });
+
+  if (radioButton === 'radiobutton_checked') {
+    UIManager.sendAccessibilityEvent(
+      findNodeHandle(this),
+      UIManager.AccessibilityEventTypes.typeViewClicked);
+  }
+}
+
+<CustomRadioButton
+  accessibilityComponentType={this.state.radioButton}
+  onPress={this._onPress}/>
+
    
+
    In the above example we've created a custom radio button that now behaves like a native one. More specifically, TalkBack now correctly announces changes to the radio button selection.
    
+
    Testing VoiceOver Support (iOS)
    
+
    To enable VoiceOver, go to the Settings app on your iOS device. Tap General, then Accessibility. There you will find many tools that people use to make their devices more usable, such as bolder text, increased contrast, and VoiceOver.
    
+
    To enable VoiceOver, tap on VoiceOver under "Vision" and toggle the switch that appears at the top.
    
+
    At the very bottom of the Accessibility settings, there is an "Accessibility Shortcut". You can use this to toggle VoiceOver by triple clicking the Home button.

    Accessibility
    Native App Accessibility (iOS and Android)
    
+
    Both iOS and Android provide APIs for making apps accessible to people with disabilities. In addition, both platforms provide bundled assistive technologies, like the screen readers VoiceOver (iOS) and TalkBack (Android) for the visually impaired. Similarly, in React Native we have included APIs designed to provide developers with support for making apps more accessible. Take note, iOS and Android differ slightly in their approaches, and thus the React Native implementations may vary by platform.
    
+
    In addition to this documentation, you might find this blog post about React Native accessibility to be useful.
    
+
    Making Apps Accessible
    
+
    Accessibility properties
    
+
    accessible (iOS, Android)
    
+
    When true, indicates that the view is an accessibility element. When a view is an accessibility element, it groups its children into a single selectable component. By default, all touchable elements are accessible.
    
+
    On Android, accessible={true} property for a react-native View will be translated into native focusable={true}.
    
+
    <View accessible={true}>
+  <Text>text one</Text>
+  <Text>text two</Text>
+</View>
+
    
+
    In the above example, we can't get accessibility focus separately on 'text one' and 'text two'. Instead we get focus on a parent view with 'accessible' property.
    
+
    accessibilityLabel (iOS, Android)
    
+
    When a view is marked as accessible, it is a good practice to set an accessibilityLabel on the view, so that people who use VoiceOver know what element they have selected. VoiceOver will read this string when a user selects the associated element.
    
+
    To use, set the accessibilityLabel property to a custom string on your View, Text or Touchable:
    
+
    <TouchableOpacity
+  accessible={true}
+  accessibilityLabel="Tap me!"
+  onPress={this._onPress}>
+  <View style={styles.button}>
+    <Text style={styles.buttonText}>Press me!</Text>
+  </View>
+</TouchableOpacity>
+
    
+
    In the above example, the accessibilityLabel on the TouchableOpacity element would default to "Press me!". The label is constructed by concatenating all Text node children separated by spaces.
    
+
    accessibilityHint (iOS, Android)
    
+
    An accessibility hint helps users understand what will happen when they perform an action on the accessibility element when that result is not obvious from the accessibility label.
    
+
    To use, set the accessibilityHint property to a custom string on your View, Text or Touchable:
    
+
    <TouchableOpacity
+  accessible={true}
+  accessibilityLabel="Go back"
+  accessibilityHint="Navigates to the previous screen"
+  onPress={this._onPress}>
+  <View style={styles.button}>
+    <Text style={styles.buttonText}>Back</Text>
+  </View>
+</TouchableOpacity>
+
    
+
    iOS In the above example, VoiceOver will read the hint after the label, if the user has hints enabled in the device's VoiceOver settings. Read more about guidelines for accessibilityHint in the iOS Developer Docs
    
+
    Android In the above example, Talkback will read the hint after the label. At this time, hints cannot be turned off on Android.
    
+
    accessibilityIgnoresInvertColors(iOS)
    
+
    Inverting screen colors is an Accessibility feature that makes the iPhone and iPad easier on the eyes for some people with a sensitivity to brightness, easier to distinguish for some people with color blindness, and easier to make out for some people with low vision. However, sometimes you have views such as photos that you don't want to be inverted. In this case, you can set this property to be false so that these specific views won't have their colors inverted.
    
+
    accessibilityRole (iOS, Android)
    
+
    
+
    Note: Accessibility Role and Accessibility States are meant to be a cross-platform solution to replace accessibilityTraits and accessibilityComponentType, which will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    
+
    Accessibility Role tells a person using either VoiceOver on iOS or TalkBack on Android the type of element that is focused on. To use, set the accessibilityRole property to one of the following strings:
    
+
      
+
    • none Used when the element has no role.
      • 
+
    • button Used when the element should be treated as a button.
      • 
+
    • link Used when the element should be treated as a link.
      • 
+
    • search Used when the text field element should also be treated as a search field.
      • 
+
    • image Used when the element should be treated as an image. Can be combined with button or link, for example.
      • 
+
    • keyboardkey Used when the element acts as a keyboard key.
      • 
+
    • text Used when the element should be treated as static text that cannot change.
      • 
+
    • adjustable Used when an element can be "adjusted" (e.g. a slider).
      • 
+
    • imagebutton Used when the element should be treated as a button and is also an image.
      • 
+
    • header Used when an element acts as a header for a content section (e.g. the title of a navigation bar).
      • 
+
    • summary Used when an element can be used to provide a quick summary of current conditions in the app when the app first launches.
      • 
+
    
+
    accessibilityStates (iOS, Android)
    
+
    
+
    Note: > accessibilityRole and accessibilityStates are meant to be a cross-platform solution to replace accessibilityTraits and accessibilityComponentType, which will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    
+
    Accessibility State tells a person using either VoiceOver on iOS or TalkBack on Android the state of the element currently focused on. The state of the element can be set either to selected or disabled or both:
    
+
      
+
    • selected Used when the element is in a selected state. For example, a button is selected.
      • 
+
    • disabled Used when the element is disabled and cannot be interacted with.
      • 
+
    
+
    To use, set the accessibilityStates to an array containing either selected, disabled, or both.
    
+
    accessibilityTraits (iOS)
    
+
    
+
    Note: accessibilityTraits will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    
+
    Accessibility traits tell a person using VoiceOver what kind of element they have selected. Is this element a label? A button? A header? These questions are answered by accessibilityTraits.
    
+
    To use, set the accessibilityTraits property to one of (or an array of) accessibility trait strings:
    
+
      
+
    • none Used when the element has no traits.
      • 
+
    • button Used when the element should be treated as a button.
      • 
+
    • link Used when the element should be treated as a link.
      • 
+
    • header Used when an element acts as a header for a content section (e.g. the title of a navigation bar).
      • 
+
    • search Used when the text field element should also be treated as a search field.
      • 
+
    • image Used when the element should be treated as an image. Can be combined with button or link, for example.
      • 
+
    • selected Used when the element is selected. For example, a selected row in a table or a selected button within a segmented control.
      • 
+
    • plays Used when the element plays its own sound when activated.
      • 
+
    • key Used when the element acts as a keyboard key.
      • 
+
    • text Used when the element should be treated as static text that cannot change.
      • 
+
    • summary Used when an element can be used to provide a quick summary of current conditions in the app when the app first launches. For example, when Weather first launches, the element with today's weather conditions is marked with this trait.
      • 
+
    • disabled Used when the control is not enabled and does not respond to user input.
      • 
+
    • frequentUpdates Used when the element frequently updates its label or value, but too often to send notifications. Allows an accessibility client to poll for changes. A stopwatch would be an example.
      • 
+
    • startsMedia Used when activating an element starts a media session (e.g. playing a movie, recording audio) that should not be interrupted by output from an assistive technology, like VoiceOver.
      • 
+
    • adjustable Used when an element can be "adjusted" (e.g. a slider).
      • 
+
    • allowsDirectInteraction Used when an element allows direct touch interaction for VoiceOver users (for example, a view representing a piano keyboard).
      • 
+
    • pageTurn Informs VoiceOver that it should scroll to the next page when it finishes reading the contents of the element.
      • 
+
    
+
    accessibilityViewIsModal (iOS)
    
+
    A Boolean value indicating whether VoiceOver should ignore the elements within views that are siblings of the receiver.
    
+
    For example, in a window that contains sibling views A and B, setting accessibilityViewIsModal to true on view B causes VoiceOver to ignore the elements in the view A. On the other hand, if view B contains a child view C and you set accessibilityViewIsModal to true on view C, VoiceOver does not ignore the elements in view A.
    
+
    accessibilityElementsHidden (iOS)
    
+
    A Boolean value indicating whether the accessibility elements contained within this accessibility element are hidden.
    
+
    For example, in a window that contains sibling views A and B, setting accessibilityElementsHidden to true on view B causes VoiceOver to ignore the elements in the view B. This is similar to the Android property importantForAccessibility="no-hide-descendants".
    
+
    onAccessibilityTap (iOS)
    
+
    Use this property to assign a custom function to be called when someone activates an accessible element by double tapping on it while it's selected.
    
+
    onMagicTap (iOS)
    
+
    Assign this property to a custom function which will be called when someone performs the "magic tap" gesture, which is a double-tap with two fingers. A magic tap function should perform the most relevant action a user could take on a component. In the Phone app on iPhone, a magic tap answers a phone call, or ends the current one. If the selected element does not have an onMagicTap function, the system will traverse up the view hierarchy until it finds a view that does.
    
+
    onAccessibilityEscape (iOS)
    
+
    Assign this property to a custom function which will be called when someone performs the "escape" gesture, which is a two finger Z shaped gesture. An escape function should move back hierarchically in the user interface. This can mean moving up or back in a navigation hierarchy or dismissing a modal user interface. If the selected element does not have an onAccessibilityEscape function, the system will attempt to traverse up the view hierarchy until it finds a view that does or bonk to indicate it was unable to find one.
    
+
    accessibilityComponentType (Android)
    
+
    
+
    Note: > accessibilityComponentType will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    
+
    In some cases, we also want to alert the end user of the type of selected component (i.e., that it is a “button”). If we were using native buttons, this would work automatically. Since we are using javascript, we need to provide a bit more context for TalkBack. To do so, you must specify the ‘accessibilityComponentType’ property for any UI component. We support 'none', ‘button’, ‘radiobutton_checked’ and ‘radiobutton_unchecked’.
    
+
    <TouchableWithoutFeedback accessibilityComponentType=”button”
+  onPress={this._onPress}>
+  <View style={styles.button}>
+    <Text style={styles.buttonText}>Press me!</Text>
+  </View>
+</TouchableWithoutFeedback>
+
    
+
    In the above example, the TouchableWithoutFeedback is being announced by TalkBack as a native Button.
    
+
    accessibilityLiveRegion (Android)
    
+
    When components dynamically change, we want TalkBack to alert the end user. This is made possible by the ‘accessibilityLiveRegion’ property. It can be set to ‘none’, ‘polite’ and ‘assertive’:
    
+
      
+
    • none Accessibility services should not announce changes to this view.
      • 
+
    • polite Accessibility services should announce changes to this view.
      • 
+
    • assertive Accessibility services should interrupt ongoing speech to immediately announce changes to this view.
      • 
+
    
+
    <TouchableWithoutFeedback onPress={this._addOne}>
+  <View style={styles.embedded}>
+    <Text>Click me</Text>
+  </View>
+</TouchableWithoutFeedback>
+<Text accessibilityLiveRegion="polite">
+  Clicked {this.state.count} times
+</Text>
+
    
+
    In the above example method _addOne changes the state.count variable. As soon as an end user clicks the TouchableWithoutFeedback, TalkBack reads text in the Text view because of its 'accessibilityLiveRegion=”polite”' property.
    
+
    importantForAccessibility (Android)
    
+
    In the case of two overlapping UI components with the same parent, default accessibility focus can have unpredictable behavior. The ‘importantForAccessibility’ property will resolve this by controlling if a view fires accessibility events and if it is reported to accessibility services. It can be set to ‘auto’, ‘yes’, ‘no’ and ‘no-hide-descendants’ (the last value will force accessibility services to ignore the component and all of its children).
    
+
    <View style={styles.container}>
+  <View style={{position: 'absolute', left: 10, top: 10, right: 10, height: 100,
+    backgroundColor: 'green'}} importantForAccessibility=”yes”>
+    <Text> First layout </Text>
+  </View>
+  <View style={{position: 'absolute', left: 10, top: 10, right: 10, height: 100,
+    backgroundColor: 'yellow'}} importantForAccessibility=”no-hide-descendants”>
+    <Text> Second layout </Text>
+  </View>
+</View>
+
    
+
    In the above example, the yellow layout and its descendants are completely invisible to TalkBack and all other accessibility services. So we can easily use overlapping views with the same parent without confusing TalkBack.
    
+
    Checking if a Screen Reader is Enabled
    
+
    The AccessibilityInfo API allows you to determine whether or not a screen reader is currently active. See the AccessibilityInfo documentation for details.
    
+
    Sending Accessibility Events (Android)
    
+
    Sometimes it is useful to trigger an accessibility event on a UI component (i.e. when a custom view appears on a screen or a custom radio button has been selected). Native UIManager module exposes a method ‘sendAccessibilityEvent’ for this purpose. It takes two arguments: view tag and a type of an event.
    
+
    import { UIManager, findNodeHandle } from 'react-native';
+
+_onPress: function() {
+  const radioButton = this.state.radioButton === 'radiobutton_checked' ?
+    'radiobutton_unchecked' : 'radiobutton_checked'
+
+  this.setState({
+    radioButton: radioButton
+  });
+
+  if (radioButton === 'radiobutton_checked') {
+    UIManager.sendAccessibilityEvent(
+      findNodeHandle(this),
+      UIManager.AccessibilityEventTypes.typeViewClicked);
+  }
+}
+
+<CustomRadioButton
+  accessibilityComponentType={this.state.radioButton}
+  onPress={this._onPress}/>
+
    
+
    In the above example we've created a custom radio button that now behaves like a native one. More specifically, TalkBack now correctly announces changes to the radio button selection.
    
+
    Testing VoiceOver Support (iOS)
    
+
    To enable VoiceOver, go to the Settings app on your iOS device. Tap General, then Accessibility. There you will find many tools that people use to make their devices more usable, such as bolder text, increased contrast, and VoiceOver.
    
+
    To enable VoiceOver, tap on VoiceOver under "Vision" and toggle the switch that appears at the top.
    
+
    At the very bottom of the Accessibility settings, there is an "Accessibility Shortcut". You can use this to toggle VoiceOver by triple clicking the Home button.

    AccessibilityInfo
    Sometimes it's useful to know whether or not the device has a screen reader that is currently active. The AccessibilityInfo API is designed for this purpose. You can use it to query the current state of the screen reader as well as to register to be notified when the state of the screen reader changes.
    
+
    Here's a small example illustrating how to use AccessibilityInfo:
    
+
    class ScreenReaderStatusExample extends React.Component {
+  state = {
+    screenReaderEnabled: false,
+  };
+
+  componentDidMount() {
+    AccessibilityInfo.addEventListener(
+      'change',
+      this._handleScreenReaderToggled,
+    );
+    AccessibilityInfo.fetch().then((isEnabled) => {
+      this.setState({
+        screenReaderEnabled: isEnabled,
+      });
+    });
+  }
+
+  componentWillUnmount() {
+    AccessibilityInfo.removeEventListener(
+      'change',
+      this._handleScreenReaderToggled,
+    );
+  }
+
+  _handleScreenReaderToggled = (isEnabled) => {
+    this.setState({
+      screenReaderEnabled: isEnabled,

    showActionSheetWithOptions()
    
+
    static showActionSheetWithOptions(options, callback)
+
    
+
    Display an iOS action sheet. The options object must contain one or more of:
    
+
      
+
    • options (array of strings) - a list of button titles (required)
      • 
+
    • cancelButtonIndex (int) - index of cancel button in options
      • 
+
    • destructiveButtonIndex (int) - index of destructive button in options
      • 
+
    • title (string) - a title to show above the action sheet
      • 
+
    • message (string) - a message to show below the title
      • 
+
    • tintColor (string) - the color used for non-destructive button titles
      • 
+
    
+
    The 'callback' function takes one parameter, the zero-based index of the selected item.
    
+
    Minimal example:
    
+
    ActionSheetIOS.showActionSheetWithOptions(
+  {
+    options: ['Cancel', 'Remove'],
+    destructiveButtonIndex: 1,
+    cancelButtonIndex: 0,

+
    showShareActionSheetWithOptions()
    
+
    static showShareActionSheetWithOptions(options, failureCallback, successCallback)
+
    
+
    Display the iOS share sheet. The options object should contain one or both of message and url and can additionally have a subject or excludedActivityTypes:
    
+
      
+
    • url (string) - a URL to share
      • 
+
    • message (string) - a message to share
      • 
+
    • subject (string) - a subject for the message
      • 
+
    • excludedActivityTypes (array) - the activities to exclude from the ActionSheet
      • 
+
    
+
    NOTE: if url points to a local file, or is a base64-encoded uri, the file it points to will be loaded and shared directly. In this way, you can share images, videos, PDF files, etc.
    
+
    The 'failureCallback' function takes one parameter, an error object. The only property defined on this object is an optional stack property of type string.
    
+
    The 'successCallback' function takes two parameters:
    
+
      
+
    • a boolean value signifying success or failure
      • 
+
    • a string that, in the case of success, indicates the method of sharing

    Edit
    Alert
    Launches an alert dialog with the specified title and message.
    
+
    Optionally provide a list of buttons. Tapping any button will fire the respective onPress callback and dismiss the alert. By default, the only button will be an 'OK' button.
    
+
    This is an API that works both on iOS and Android and can show static alerts. To show an alert that prompts the user to enter some information, see AlertIOS; entering text in an alert is common on iOS only.
    
+
    Example
    
+
+  
+    
+    
+  
+  
+    
+    
+

+      
    
+    
    
+
    iOS
    
+
    On iOS you can specify any number of buttons. Each button can optionally specify a style, which is one of 'default', 'cancel' or 'destructive'.
    
+
    Android
    
+
    On Android at most three buttons can be specified. Android has a concept of a neutral, negative and a positive button:
    
+
      
+
    • If you specify one button, it will be the 'positive' one (such as 'OK')
      • 
+
    • Two buttons mean 'negative', 'positive' (such as 'Cancel', 'OK')
      • 
+
    • Three buttons mean 'neutral', 'negative', 'positive' (such as 'Later', 'Cancel', 'OK')
      • 
+
    
+
    By default alerts on Android can be dismissed by tapping outside of the alert box. This event can be handled by providing an optional options parameter, with an onDismiss callback property { onDismiss: () => {} }.
    
+
    Alternatively, the dismissing behavior can be disabled altogether by providing an optional options parameter with the cancelable property set to false i.e. { cancelable: false }
    
+
    Example usage:
    
+
    // Works on both iOS and Android
+Alert.alert(
+  'Alert Title',
+  'My Alert Msg',
+  [
+    {text: 'Ask me later', onPress: () => console.log('Ask me later pressed')},

+      onPress: () => console.log('Cancel Pressed'),

    Animated
    The Animated library is designed to make animations fluid, powerful, and easy to build and maintain. Animated focuses on declarative relationships between inputs and outputs, with configurable transforms in between, and simple start/stop methods to control time-based animation execution.
    
+
    The simplest workflow for creating an animation is to create an Animated.Value, hook it up to one or more style attributes of an animated component, and then drive updates via animations using Animated.timing():
    
+
    Animated.timing(
+  // Animate value over time
+  this.state.fadeAnim, // The value to drive
+  {
+    toValue: 1, // Animate to final value of 1
+  },
+).start(); // Start the animation
+
    
+
    Refer to the Animations guide to see additional examples of Animated in action.
    
+
    Overview
    
+
    There are two value types you can use with Animated:
    
+
+
    Animated.Value can bind to style properties or other props, and can be interpolated as well. A single Animated.Value can drive any number of properties.
    
+
    Configuring animations
    
+
    Animated provides three types of animation types. Each animation type provides a particular animation curve that controls how your values animate from their initial value to the final value:
    
+
+
    In most cases, you will be using timing(). By default, it uses a symmetric easeInOut curve that conveys the gradual acceleration of an object to full speed and concludes by gradually decelerating to a stop.
    
+
    Working with animations
    
+
    Animations are started by calling start() on your animation. start() takes a completion callback that will be called when the animation is done. If the animation finished running normally, the completion callback will be invoked with {finished: true}. If the animation is done because stop() was called on it before it could finish (e.g. because it was interrupted by a gesture or another animation), then it will receive {finished: false}.
    
+
    Using the native driver
    
+
    By using the native driver, we send everything about the animation to native before starting the animation, allowing native code to perform the animation on the UI thread without having to go through the bridge on every frame. Once the animation has started, the JS thread can be blocked without affecting the animation.
    
+
    You can use the native driver by specifying useNativeDriver: true in your animation configuration. See the Animations guide to learn more.
    
+
    Animatable components
    
+
    Only animatable components can be animated. These special components do the magic of binding the animated values to the properties, and do targeted native updates to avoid the cost of the react render and reconciliation process on every frame. They also handle cleanup on unmount so they are safe by default.
    
+
+
    Animated exports the following animatable components using the above wrapper:
    
+
      
+
    • Animated.Image
      • 
+
    • Animated.ScrollView
      • 
+
    • Animated.Text
      • 
+
    • Animated.View
      • 
+
    
+
    Composing animations
    
+
    Animations can also be combined in complex ways using composition functions:
    
+
+
    Animations can also be chained together simply by setting the toValue of one animation to be another Animated.Value. See Tracking dynamic values in the Animations guide.
    
+
    By default, if one animation is stopped or interrupted, then all other animations in the group are also stopped.
    
+
    Combining animated values
    
+
    You can combine two animated values via addition, subtraction, multiplication, division, or modulo to make a new animated value:
    
+
+
    Interpolation
    
+
    The interpolate() function allows input ranges to map to different output ranges. By default, it will extrapolate the curve beyond the ranges given, but you can also have it clamp the output value. It uses lineal interpolation by default but also supports easing functions.
    
+
+
    Read more about interpolation in the Animation guide.
    
+
    Handling gestures and other events
    
+
    Gestures, like panning or scrolling, and other events can map directly to animated values using Animated.event(). This is done with a structured map syntax so that values can be extracted from complex event objects. The first level is an array to allow mapping across multiple args, and that array contains nested objects.
    
+
+
    For example, when working with horizontal scrolling gestures, you would do the following in order to map event.nativeEvent.contentOffset.x to scrollX (an Animated.Value):
    
+
     onScroll={Animated.event(
+   // scrollX = e.nativeEvent.contentOffset.x
+   [{ nativeEvent: {
+        contentOffset: {
+          x: scrollX
+        }
+      }
+    }]
+ )}

    When the given value is a ValueXY instead of a Value, each config option may be a vector of the form {x: ..., y: ...} instead of a scalar.
    
+
    decay()
    
+
    static decay(value, config)
+
    
+
    Animates a value from an initial velocity to zero based on a decay coefficient.
    
+
    Config is an object that may have the following options:
    
+
      
+
    • velocity: Initial velocity. Required.
      • 
+
    • deceleration: Rate of decay. Default 0.997.
      • 
+
    • isInteraction: Whether or not this animation creates an "interaction handle" on the InteractionManager. Default true.
      • 
+
    • useNativeDriver: Uses the native driver when true. Default false.
      • 
+
    
+
    
+
    timing()
    
+
    static timing(value, config)
+
    
+
    Animates a value along a timed easing curve. The Easing module has tons of predefined curves, or you can use your own function.
    
+
    Config is an object that may have the following options:
    
+
      
+
    • duration: Length of animation (milliseconds). Default 500.
      • 
+
    • easing: Easing function to define curve. Default is Easing.inOut(Easing.ease).
      • 
+
    • delay: Start the animation after delay (milliseconds). Default 0.
      • 
+
    • isInteraction: Whether or not this animation creates an "interaction handle" on the InteractionManager. Default true.

+
    
+
    spring()
    
+
    static spring(value, config)
+
    
+
    Animates a value according to an analytical spring model based on damped harmonic oscillation. Tracks velocity state to create fluid motions as the toValue updates, and can be chained together.
    
+
    Config is an object that may have the following options.
    
+
    Note that you can only define one of bounciness/speed, tension/friction, or stiffness/damping/mass, but not more than one:
    
+
    The friction/tension or bounciness/speed options match the spring model in Facebook Pop, Rebound, and Origami.
    
+
      
+
    • friction: Controls "bounciness"/overshoot. Default 7.
      • 
+
    • tension: Controls speed. Default 40.
      • 
+
    • speed: Controls speed of the animation. Default 12.
      • 
+
    • bounciness: Controls bounciness. Default 8.
      • 
+
    
+
    Specifying stiffness/damping/mass as parameters makes Animated.spring use an analytical spring model based on the motion equations of a damped harmonic oscillator. This behavior is slightly more precise and faithful to the physics behind spring dynamics, and closely mimics the implementation in iOS's CASpringAnimation primitive.
    
+
      
+
    • stiffness: The spring stiffness coefficient. Default 100.
      • 
+
    • damping: Defines how the spring’s motion should be damped due to the forces of friction. Default 10.
      • 
+
    • mass: The mass of the object attached to the end of the spring. Default 1.
      • 
+
    
+
    Other configuration options are as follows:
    
+
      
+
    • velocity: The initial velocity of the object attached to the spring. Default 0 (object is at rest).
      • 
+
    • overshootClamping: Boolean indicating whether the spring should be clamped and not bounce. Default false.
      • 
+
    • restDisplacementThreshold: The threshold of displacement from rest below which the spring should be considered at rest. Default 0.001.
      • 
+
    • restSpeedThreshold: The speed at which the spring should be considered at rest in pixels per second. Default 0.001.
      • 
+
    • delay: Start the animation after delay (milliseconds). Default 0.
      • 
+
    • isInteraction: Whether or not this animation creates an "interaction handle" on the InteractionManager. Default true.
      • 
+
    • useNativeDriver: Uses the native driver when true. Default false.
      • 
+
    
+
    
+
    add()
    
+
    static add(a, b)
+
    
+
    Creates a new Animated value composed from two Animated values added together.
    
+
    
+
    subtract()
    
+
    static subtract(a, b)
+
    
+
    Creates a new Animated value composed by subtracting the second Animated value from the first Animated value.
    
+
    
+
    divide()
    
+
    static divide(a, b)
+
    
+
    Creates a new Animated value composed by dividing the first Animated value by the second Animated value.
    
+
    
+
    multiply()
    
+
    static multiply(a, b)
+
    
+
    Creates a new Animated value composed from two Animated values multiplied together.
    
+
    
+
    modulo()
    
+
    static modulo(a, modulus)
+
    
+
    Creates a new Animated value that is the (non-negative) modulo of the provided Animated value
    
+
    
+
    diffClamp()
    
+
    static diffClamp(a, min, max)
+
    
+
    Create a new Animated value that is limited between 2 values. It uses the difference between the last value so even if the value is far from the bounds it will start changing when the value starts getting closer again. (value = clamp(value + diff, min, max)).
    
+
    This is useful with scroll events, for example, to show the navbar when scrolling up and to hide it when scrolling down.
    
+
    
+
    delay()
    
+
    static delay(time)
+
    
+
    Starts an animation after the given delay.
    
+
    
+
    sequence()
    
+
    static sequence(animations)
+
    
+
    Starts an array of animations in order, waiting for each to complete before starting the next. If the current running animation is stopped, no following animations will be started.
    
+
    
+
    parallel()
    
+
    static parallel(animations, config?)
+
    
+
    Starts an array of animations all at the same time. By default, if one of the animations is stopped, they will all be stopped. You can override this with the stopTogether flag.
    
+
    
+
    stagger()
    
+
    static stagger(time, animations)
+
    
+
    Array of animations may run in parallel (overlap), but are started in sequence with successive delays. Nice for doing trailing effects.
    
+
    
+
    loop()
    
+
    static loop(animation, config?)
+
    
+
    Loops a given animation continuously, so that each time it reaches the end, it resets and begins again from the start. Will loop without blocking the UI thread if the child animation is set to useNativeDriver: true. In addition, loops can prevent VirtualizedList-based components from rendering more rows while the animation is running. You can pass isInteraction: false in the child animation config to fix this.
    
+
    Config is an object that may have the following options:
    
+
      
+
    • iterations: Number of times the animation should loop. Default -1 (infinite).
      • 
+
    
+
    
+
    event()
    
+
    static event(argMapping, config?)
+
    
+
    Takes an array of mappings and extracts values from each arg accordingly, then calls setValue on the mapped outputs. e.g.
    
+
     onScroll={Animated.event(
+   [{nativeEvent: {contentOffset: {x: this._scrollX}}}],
+   {listener: (event) => console.log(event)}, // Optional async listener
+ )}
+ ...
+ onPanResponderMove: Animated.event([
+   null,                // raw event arg ignored
+   {dx: this._panX}],    // gestureState arg
+{listener: (event, gestureState) => console.log(event, gestureState)}, // Optional async listener
+ ),
+
    
+
    Config is an object that may have the following options:
    
+
      
+
    • listener: Optional async listener.
      • 
+
    • useNativeDriver: Uses the native driver when true. Default false.
      • 
+
    
+
    
+
    forkEvent()
    
+
    static forkEvent(event, listener)
+
    
+
    Advanced imperative API for snooping on animated events that are passed in through props. It permits to add a new javascript listener to an existing AnimatedEvent. If animatedEvent is a simple javascript listener, it will merge the 2 listeners into a single one, and if animatedEvent is null/undefined, it will assign the javascript listener directly. Use values directly where possible.
    
+
    
+
    unforkEvent()
    
+
    static unforkEvent(event, listener)
+
    
+

    Animated
    The Animated library is designed to make animations fluid, powerful, and easy to build and maintain. Animated focuses on declarative relationships between inputs and outputs, with configurable transforms in between, and simple start/stop methods to control time-based animation execution.
    
+
    The simplest workflow for creating an animation is to create an Animated.Value, hook it up to one or more style attributes of an animated component, and then drive updates via animations using Animated.timing():
    
+
    Animated.timing(
+  // Animate value over time
+  this.state.fadeAnim, // The value to drive
+  {
+    toValue: 1, // Animate to final value of 1
+  },
+).start(); // Start the animation
+
    
+
    Refer to the Animations guide to see additional examples of Animated in action.
    
+
    Overview
    
+
    There are two value types you can use with Animated:
    
+
+
    Animated.Value can bind to style properties or other props, and can be interpolated as well. A single Animated.Value can drive any number of properties.
    
+
    Configuring animations
    
+
    Animated provides three types of animation types. Each animation type provides a particular animation curve that controls how your values animate from their initial value to the final value:
    
+
+
    In most cases, you will be using timing(). By default, it uses a symmetric easeInOut curve that conveys the gradual acceleration of an object to full speed and concludes by gradually decelerating to a stop.
    
+
    Working with animations
    
+
    Animations are started by calling start() on your animation. start() takes a completion callback that will be called when the animation is done. If the animation finished running normally, the completion callback will be invoked with {finished: true}. If the animation is done because stop() was called on it before it could finish (e.g. because it was interrupted by a gesture or another animation), then it will receive {finished: false}.
    
+
    Using the native driver
    
+
    By using the native driver, we send everything about the animation to native before starting the animation, allowing native code to perform the animation on the UI thread without having to go through the bridge on every frame. Once the animation has started, the JS thread can be blocked without affecting the animation.
    
+
    You can use the native driver by specifying useNativeDriver: true in your animation configuration. See the Animations guide to learn more.
    
+
    Animatable components
    
+
    Only animatable components can be animated. These special components do the magic of binding the animated values to the properties, and do targeted native updates to avoid the cost of the react render and reconciliation process on every frame. They also handle cleanup on unmount so they are safe by default.
    
+
+
    Animated exports the following animatable components using the above wrapper:
    
+
      
+
    • Animated.Image
      • 
+
    • Animated.ScrollView
      • 
+
    • Animated.Text
      • 
+
    • Animated.View
      • 
+
    
+
    Composing animations
    
+
    Animations can also be combined in complex ways using composition functions:
    
+
+
    Animations can also be chained together simply by setting the toValue of one animation to be another Animated.Value. See Tracking dynamic values in the Animations guide.
    
+
    By default, if one animation is stopped or interrupted, then all other animations in the group are also stopped.
    
+
    Combining animated values
    
+
    You can combine two animated values via addition, subtraction, multiplication, division, or modulo to make a new animated value:
    
+
+
    Interpolation
    
+
    The interpolate() function allows input ranges to map to different output ranges. By default, it will extrapolate the curve beyond the ranges given, but you can also have it clamp the output value. It uses lineal interpolation by default but also supports easing functions.
    
+
+
    Read more about interpolation in the Animation guide.
    
+
    Handling gestures and other events
    
+
    Gestures, like panning or scrolling, and other events can map directly to animated values using Animated.event(). This is done with a structured map syntax so that values can be extracted from complex event objects. The first level is an array to allow mapping across multiple args, and that array contains nested objects.
    
+
+
    For example, when working with horizontal scrolling gestures, you would do the following in order to map event.nativeEvent.contentOffset.x to scrollX (an Animated.Value):
    
+
     onScroll={Animated.event(
+   // scrollX = e.nativeEvent.contentOffset.x
+   [{ nativeEvent: {
+        contentOffset: {
+          x: scrollX
+        }
+      }
+    }]
+ )}

    static modulo(a, modulus)
+
    
+
    Creates a new Animated value that is the (non-negative) modulo of the provided Animated value
    
+
    
+
    diffClamp()
    
+
    static diffClamp(a, min, max)
+
    
+
    Create a new Animated value that is limited between 2 values. It uses the difference between the last value so even if the value is far from the bounds it will start changing when the value starts getting closer again. (value = clamp(value + diff, min, max)).
    
+
    This is useful with scroll events, for example, to show the navbar when scrolling up and to hide it when scrolling down.
    
+
    
+
    delay()
    
+
    static delay(time)
+
    
+
    Starts an animation after the given delay.
    
+
    
+
    sequence()
    
+
    static sequence(animations)
+
    
+
    Starts an array of animations in order, waiting for each to complete before starting the next. If the current running animation is stopped, no following animations will be started.
    
+
    
+
    parallel()
    
+
    static parallel(animations, config?)
+
    
+
    Starts an array of animations all at the same time. By default, if one of the animations is stopped, they will all be stopped. You can override this with the stopTogether flag.
    
+
    
+
    stagger()
    
+
    static stagger(time, animations)
+
    
+
    Array of animations may run in parallel (overlap), but are started in sequence with successive delays. Nice for doing trailing effects.
    
+
    
+
    loop()
    
+
    static loop(animation, config?)
+
    
+
    Loops a given animation continuously, so that each time it reaches the end, it resets and begins again from the start. Will loop without blocking the UI thread if the child animation is set to useNativeDriver: true. In addition, loops can prevent VirtualizedList-based components from rendering more rows while the animation is running. You can pass isInteraction: false in the child animation config to fix this.
    
+
    Config is an object that may have the following options:
    
+
      
+
    • iterations: Number of times the animation should loop. Default -1 (infinite).
      • 
+
    
+
    
+
    event()
    
+
    static event(argMapping, config?)
+
    
+
    Takes an array of mappings and extracts values from each arg accordingly, then calls setValue on the mapped outputs. e.g.
    
+
     onScroll={Animated.event(
+   [{nativeEvent: {contentOffset: {x: this._scrollX}}}],
+   {listener: (event) => console.log(event)}, // Optional async listener
+ )}
+ ...
+ onPanResponderMove: Animated.event([
+   null,                // raw event arg ignored
+   {dx: this._panX}],    // gestureState arg
+{listener: (event, gestureState) => console.log(event, gestureState)}, // Optional async listener
+ ),
+
    
+
    Config is an object that may have the following options:
    
+
      
+
    • listener: Optional async listener.
      • 
+
    • useNativeDriver: Uses the native driver when true. Default false.
      • 
+
    
+
    
+
    forkEvent()
    
+
    static forkEvent(event, listener)
+
    
+
    Advanced imperative API for snooping on animated events that are passed in through props. It permits to add a new javascript listener to an existing AnimatedEvent. If animatedEvent is a simple javascript listener, it will merge the 2 listeners into a single one, and if animatedEvent is null/undefined, it will assign the javascript listener directly. Use values directly where possible.
    
+
    
+
    unforkEvent()
    
+
    static unforkEvent(event, listener)
+
    
+
    Properties
    
+
    Value
    
+
    Standard value class for driving animations. Typically initialized with new Animated.Value(0);
    
+
    
+
    ValueXY
    
+
    2D value class for driving 2D animations, such as pan gestures.
    
+
    
+
    Interpolation
    
+
    Exported to use the Interpolation type in flow.
    
+
    
+
    Node
    
+
    Exported for ease of type checking. All animated values derive from this class.
    
+
    
+
    createAnimatedComponent
    
+
    Make any React component Animatable. Used to create Animated.View, etc.
    
+
    
+
    attachNativeEvent
    
+
    Imperative API to attach an animated value to an event on a view. Prefer using Animated.event with useNativeDrive: true if possible.

    AnimatedValue
    Standard value for driving animations. One Animated.Value can drive multiple properties in a synchronized fashion, but can only be driven by one mechanism at a time. Using a new mechanism (e.g. starting a new animation, or calling setValue) will stop any previous ones.
    
+
    Typically initialized with new Animated.Value(0);
    
+
    See also Animated.

    Edit
    AnimatedValueXY
    2D Value for driving 2D animations, such as pan gestures. Almost identical API to normal Animated.Value, but multiplexed. Contains two regular Animated.Values under the hood.
    
+
    See also Animated.
    
+
    Example
    
+
    class DraggableView extends React.Component {
+  constructor(props) {
+    super(props);
+    this.state = {
+      pan: new Animated.ValueXY(), // inits to zero
+    };
+    this.state.panResponder = PanResponder.create({
+      onStartShouldSetPanResponder: () => true,
+      onPanResponderMove: Animated.event([
+        null,
+        {
+          dx: this.state.pan.x, // x,y are Animated.Value
+          dy: this.state.pan.y,
+        },
+      ]),
+      onPanResponderRelease: () => {
+        Animated.spring(
+          this.state.pan, // Auto-multiplexed
+          {toValue: {x: 0, y: 0}}, // Back to zero
+        ).start();
+      },
+    });

+Animations · React Native
    0.58
    Edit
    Animations
    Animations are very important to create a great user experience. Stationary objects must overcome inertia as they start moving. Objects in motion have momentum and rarely come to a stop immediately. Animations allow you to convey physically believable motion in your interface.
    
+
    React Native provides two complementary animation systems: Animated for granular and interactive control of specific values, and LayoutAnimation for animated global layout transactions.
    
+
    Animated API
    
+
    The Animated API is designed to make it very easy to concisely express a wide variety of interesting animation and interaction patterns in a very performant way. Animated focuses on declarative relationships between inputs and outputs, with configurable transforms in between, and simple start/stop methods to control time-based animation execution.
    
+
    Animated exports four animatable component types: View, Text, Image, and ScrollView, but you can also create your own using Animated.createAnimatedComponent().
    
+
    For example, a container view that fades in when it is mounted may look like this:
    
+
    Let's break down what's happening here. In the FadeInView constructor, a new Animated.Value called fadeAnim is initialized as part of state. The opacity property on the View is mapped to this animated value. Behind the scenes, the numeric value is extracted and used to set opacity.
    
+
    When the component mounts, the opacity is set to 0. Then, an easing animation is started on the fadeAnim animated value, which will update all of its dependent mappings (in this case, just the opacity) on each frame as the value animates to the final value of 1.
    
+
    This is done in an optimized way that is faster than calling setState and re-rendering.
    
+Because the entire configuration is declarative, we will be able to implement further optimizations that serialize the configuration and runs the animation on a high-priority thread.
    
+
    Configuring animations
    
+
    Animations are heavily configurable. Custom and predefined easing functions, delays, durations, decay factors, spring constants, and more can all be tweaked depending on the type of animation.
    
+
    Animated provides several animation types, the most commonly used one being Animated.timing(). It supports animating a value over time using one of various predefined easing functions, or you can use your own. Easing functions are typically used in animation to convey gradual acceleration and deceleration of objects.
    
+
    By default, timing will use a easeInOut curve that conveys gradual acceleration to full speed and concludes by gradually decelerating to a stop. You can specify a different easing function by passing a easing parameter. Custom duration or even a delay before the animation starts is also supported.
    
+
    For example, if we want to create a 2-second long animation of an object that slightly backs up before moving to its final position:
    
+
    Animated.timing(this.state.xPosition, {
+  toValue: 100,
+  easing: Easing.back(),
+  duration: 2000,
+}).start();
+
    
+
    Take a look at the Configuring animations section of the Animated API reference to learn more about all the config parameters supported by the built-in animations.
    
+
    Composing animations
    
+
    Animations can be combined and played in sequence or in parallel. Sequential animations can play immediately after the previous animation has finished, or they can start after a specified delay. The Animated API provides several methods, such as sequence() and delay(), each of which simply take an array of animations to execute and automatically calls start()/stop() as needed.
    
+
    For example, the following animation coasts to a stop, then it springs back while twirling in parallel:
    
+
    Animated.sequence([
+  // decay, then spring to start and twirl
+  Animated.decay(position, {
+    // coast to a stop
+    velocity: {x: gestureState.vx, y: gestureState.vy}, // velocity from gesture release
+    deceleration: 0.997,
+  }),
+  Animated.parallel([
+    // after decay, in parallel:
+    Animated.spring(position, {
+      toValue: {x: 0, y: 0}, // return to start
+    }),
+    Animated.timing(twirl, {
+      // and twirl
+      toValue: 360,
+    }),
+  ]),
+]).start(); // start the sequence group
+
    
+
    If one animation is stopped or interrupted, then all other animations in the group are also stopped. Animated.parallel has a stopTogether option that can be set to false to disable this.
    
+
    You can find a full list of composition methods in the Composing animations section of the Animated API reference.
    
+
    Combining animated values
    
+
    You can combine two animated values via addition, multiplication, division, or modulo to make a new animated value.
    
+
    There are some cases where an animated value needs to invert another animated value for calculation. An example is inverting a scale (2x --> 0.5x):
    
+
    const a = new Animated.Value(1);
+const b = Animated.divide(1, a);
+
+Animated.spring(a, {
+  toValue: 2,
+}).start();
+
    
+
    Interpolation
    
+
    Each property can be run through an interpolation first. An interpolation maps input ranges to output ranges, typically using a linear interpolation but also supports easing functions. By default, it will extrapolate the curve beyond the ranges given, but you can also have it clamp the output value.
    
+
    A simple mapping to convert a 0-1 range to a 0-100 range would be:
    
+
    value.interpolate({
+  inputRange: [0, 1],
+  outputRange: [0, 100],
+});
+
    
+
    For example, you may want to think about your Animated.Value as going from 0 to 1, but animate the position from 150px to 0px and the opacity from 0 to 1. This can easily be done by modifying style from the example above like so:
    
+
      style={{
+    opacity: this.state.fadeAnim, // Binds directly
+    transform: [{
+      translateY: this.state.fadeAnim.interpolate({
+        inputRange: [0, 1],
+        outputRange: [150, 0]  // 0 : 150, 0.5 : 75, 1 : 0
+      }),
+    }],
+  }}
+
    
+
    interpolate() supports multiple range segments as well, which is handy for defining dead zones and other handy tricks. For example, to get a negation relationship at -300 that goes to 0 at -100, then back up to 1 at 0, and then back down to zero at 100 followed by a dead-zone that remains at 0 for everything beyond that, you could do:
    
+
    value.interpolate({
+  inputRange: [-300, -100, 0, 100, 101],
+  outputRange: [300, 0, 1, 0, 0],
+});
+
    
+
    Which would map like so:
    
+
    Input | Output
+------|-------
+  -400|    450
+  -300|    300
+  -200|    150
+  -100|      0
+   -50|    0.5
+     0|      1
+    50|    0.5
+   100|      0
+   101|      0
+   200|      0
+
    
+
    interpolate() also supports mapping to strings, allowing you to animate colors as well as values with units. For example, if you wanted to animate a rotation you could do:
    
+
    value.interpolate({
+  inputRange: [0, 360],
+  outputRange: ['0deg', '360deg'],
+});
+
    
+
    interpolate() also supports arbitrary easing functions, many of which are already implemented in the Easing module. interpolate() also has configurable behavior for extrapolating the outputRange. You can set the extrapolation by setting the extrapolate, extrapolateLeft, or extrapolateRight options. The default value is extend but you can use clamp to prevent the output value from exceeding outputRange.
    
+
    Tracking dynamic values
    
+
    Animated values can also track other values. Just set the toValue of an animation to another animated value instead of a plain number. For example, a "Chat Heads" animation like the one used by Messenger on Android could be implemented with a spring() pinned on another animated value, or with timing() and a duration of 0 for rigid tracking. They can also be composed with interpolations:
    
+
    Animated.spring(follower, {toValue: leader}).start();
+Animated.timing(opacity, {
+  toValue: pan.x.interpolate({
+    inputRange: [0, 300],
+    outputRange: [1, 0],
+  }),
+}).start();
+
    
+
    The leader and follower animated values would be implemented using Animated.ValueXY(). ValueXY is a handy way to deal with 2D interactions, such as panning or dragging. It is a simple wrapper that basically contains two Animated.Value instances and some helper functions that call through to them, making ValueXY a drop-in replacement for Value in many cases. It allows us to track both x and y values in the example above.
    
+
    Tracking gestures
    
+
    Gestures, like panning or scrolling, and other events can map directly to animated values using Animated.event. This is done with a structured map syntax so that values can be extracted from complex event objects. The first level is an array to allow mapping across multiple args, and that array contains nested objects.
    
+
    For example, when working with horizontal scrolling gestures, you would do the following in order to map event.nativeEvent.contentOffset.x to scrollX (an Animated.Value):
    
+
     onScroll={Animated.event(
+   // scrollX = e.nativeEvent.contentOffset.x
+   [{ nativeEvent: {
+        contentOffset: {
+          x: scrollX
+        }
+      }
+    }]
+ )}
+
    
+
    When using PanResponder, you could use the following code to extract the x and y positions from gestureState.dx and gestureState.dy. We use a null in the first position of the array, as we are only interested in the second argument passed to the PanResponder handler, which is the gestureState.
    
+
    onPanResponderMove={Animated.event(
+  [null, // ignore the native event
+  // extract dx and dy from gestureState
+  // like 'pan.x = gestureState.dx, pan.y = gestureState.dy'
+  {dx: pan.x, dy: pan.y}
+])}
+
    
+
    Responding to the current animation value
    
+
    You may notice that there is no obvious way to read the current value while animating. This is because the value may only be known in the native runtime due to optimizations. If you need to run JavaScript in response to the current value, there are two approaches:
    
+
      
+
    • spring.stopAnimation(callback) will stop the animation and invoke callback with the final value. This is useful when making gesture transitions.
      • 
+
    • spring.addListener(callback) will invoke callback asynchronously while the animation is running, providing a recent value. This is useful for triggering state changes, for example snapping a bobble to a new option as the user drags it closer, because these larger state changes are less sensitive to a few frames of lag compared to continuous gestures like panning which need to run at 60 fps.
      • 
+
    
+
    Animated is designed to be fully serializable so that animations can be run in a high performance way, independent of the normal JavaScript event loop. This does influence the API, so keep that in mind when it seems a little trickier to do something compared to a fully synchronous system. Check out Animated.Value.addListener as a way to work around some of these limitations, but use it sparingly since it might have performance implications in the future.
    
+
    Using the native driver
    
+
    The Animated API is designed to be serializable. By using the native driver, we send everything about the animation to native before starting the animation, allowing native code to perform the animation on the UI thread without having to go through the bridge on every frame. Once the animation has started, the JS thread can be blocked without affecting the animation.
    
+
    Using the native driver for normal animations is quite simple. Just add useNativeDriver: true to the animation config when starting it.
    
+
    Animated.timing(this.state.animatedValue, {
+  toValue: 1,
+  duration: 500,
+  useNativeDriver: true, // <-- Add this
+}).start();
+
    
+
    Animated values are only compatible with one driver so if you use native driver when starting an animation on a value, make sure every animation on that value also uses the native driver.
    
+
    The native driver also works with Animated.event. This is especially useful for animations that follow the scroll position as without the native driver, the animation will always run a frame behind the gesture due to the async nature of React Native.
    
+
    <Animated.ScrollView // <-- Use the Animated ScrollView wrapper
+  scrollEventThrottle={1} // <-- Use 1 here to make sure no events are ever missed
+  onScroll={Animated.event(
+    [
+      {
+        nativeEvent: {
+          contentOffset: {y: this.state.animatedValue},
+        },
+      },
+    ],
+    {useNativeDriver: true}, // <-- Add this
+  )}>
+  {content}
+</Animated.ScrollView>
+
    
+
    You can see the native driver in action by running the RNTester app, then loading the Native Animated Example. You can also take a look at the source code to learn how these examples were produced.
    
+
    Caveats
    
+
    Not everything you can do with Animated is currently supported by the native driver. The main limitation is that you can only animate non-layout properties: things like transform and opacity will work, but flexbox and position properties will not. When using Animated.event, it will only work with direct events and not bubbling events. This means it does not work with PanResponder but does work with things like ScrollView#onScroll.
    
+
    When an animation is running, it can prevent VirtualizedList components from rendering more rows. If you need to run a long or looping animation while the user is scrolling through a list, you can use isInteraction: false in your animation's config to prevent this issue.
    
+
    Bear in mind
    
+
    While using transform styles such as rotateY, rotateX, and others ensure the transform style perspective is in place. At this time some animations may not render on Android without it. Example below.
    
+
    <Animated.View
+  style={{
+    transform: [
+      {scale: this.state.scale},
+      {rotateY: this.state.rotateY},
+      {perspective: 1000}, // without this line this Animation will not render on Android while working fine on iOS
+    ],
+  }}
+/>
+
    
+
    Additional examples
    
+
    The RNTester app has various examples of Animated in use:
    
+
+
    LayoutAnimation API
    
+
    LayoutAnimation allows you to globally configure create and update animations that will be used for all views in the next render/layout cycle. This is useful for doing flexbox layout updates without bothering to measure or calculate specific properties in order to animate them directly, and is especially useful when layout changes may affect ancestors, for example a "see more" expansion that also increases the size of the parent and pushes down the row below which would otherwise require explicit coordination between the components in order to animate them all in sync.
    
+
    Note that although LayoutAnimation is very powerful and can be quite useful, it provides much less control than Animated and other animation libraries, so you may need to use another approach if you can't get LayoutAnimation to do what you want.
    
+
    Note that in order to get this to work on Android you need to set the following flags via UIManager:
    
+
    UIManager.setLayoutAnimationEnabledExperimental &&
+  UIManager.setLayoutAnimationEnabledExperimental(true);
+
    
+
    This example uses a preset value, you can customize the animations as you need, see LayoutAnimation.js for more information.
    
+
    Additional notes
    
+
    requestAnimationFrame
    
+
    requestAnimationFrame is a polyfill from the browser that you might be familiar with. It accepts a function as its only argument and calls that function before the next repaint. It is an essential building block for animations that underlies all of the JavaScript-based animation APIs. In general, you shouldn't need to call this yourself - the animation APIs will manage frame updates for you.
    
+
    setNativeProps
    
+
    As mentioned in the Direct Manipulation section, setNativeProps allows us to modify properties of native-backed components (components that are actually backed by native views, unlike composite components) directly, without having to setState and re-render the component hierarchy.
    
+
    We could use this in the Rebound example to update the scale - this might be helpful if the component that we are updating is deeply nested and hasn't been optimized with shouldComponentUpdate.
    
+
    If you find your animations with dropping frames (performing below 60 frames per second), look into using setNativeProps or shouldComponentUpdate to optimize them. Or you could run the animations on the UI thread rather than the JavaScript thread with the useNativeDriver option. You may also want to defer any computationally intensive work until after animations are complete, using the InteractionManager. You can monitor the frame rate by using the In-App Developer Menu "FPS Monitor" tool.

+
    Animated provides several animation types, the most commonly used one being Animated.timing(). It supports animating a value over time using one of various predefined easing functions, or you can use your own. Easing functions are typically used in animation to convey gradual acceleration and deceleration of objects.
    
+
    By default, timing will use a easeInOut curve that conveys gradual acceleration to full speed and concludes by gradually decelerating to a stop. You can specify a different easing function by passing a easing parameter. Custom duration or even a delay before the animation starts is also supported.
    
+
    For example, if we want to create a 2-second long animation of an object that slightly backs up before moving to its final position:
    
+
    Animated.timing(this.state.xPosition, {
+  toValue: 100,
+  easing: Easing.back(),
+  duration: 2000,
+}).start();
+
    
+
    Take a look at the Configuring animations section of the Animated API reference to learn more about all the config parameters supported by the built-in animations.
    
+
    Composing animations
    
+
    Animations can be combined and played in sequence or in parallel. Sequential animations can play immediately after the previous animation has finished, or they can start after a specified delay. The Animated API provides several methods, such as sequence() and delay(), each of which simply take an array of animations to execute and automatically calls start()/stop() as needed.
    
+
    For example, the following animation coasts to a stop, then it springs back while twirling in parallel:
    
+
    Animated.sequence([
+  // decay, then spring to start and twirl
+  Animated.decay(position, {
+    // coast to a stop
+    velocity: {x: gestureState.vx, y: gestureState.vy}, // velocity from gesture release
+    deceleration: 0.997,
+  }),
+  Animated.parallel([
+    // after decay, in parallel:
+    Animated.spring(position, {
+      toValue: {x: 0, y: 0}, // return to start
+    }),
+    Animated.timing(twirl, {
+      // and twirl
+      toValue: 360,
+    }),
+  ]),
+]).start(); // start the sequence group
+
    
+
    If one animation is stopped or interrupted, then all other animations in the group are also stopped. Animated.parallel has a stopTogether option that can be set to false to disable this.
    
+
    You can find a full list of composition methods in the Composing animations section of the Animated API reference.
    
+
    Combining animated values
    
+
    You can combine two animated values via addition, multiplication, division, or modulo to make a new animated value.
    
+
    There are some cases where an animated value needs to invert another animated value for calculation. An example is inverting a scale (2x --> 0.5x):
    
+
    const a = new Animated.Value(1);
+const b = Animated.divide(1, a);
+
+Animated.spring(a, {
+  toValue: 2,
+}).start();
+
    
+
    Interpolation
    
+
    Each property can be run through an interpolation first. An interpolation maps input ranges to output ranges, typically using a linear interpolation but also supports easing functions. By default, it will extrapolate the curve beyond the ranges given, but you can also have it clamp the output value.
    
+
    A simple mapping to convert a 0-1 range to a 0-100 range would be:
    
+
    value.interpolate({
+  inputRange: [0, 1],
+  outputRange: [0, 100],
+});
+
    
+
    For example, you may want to think about your Animated.Value as going from 0 to 1, but animate the position from 150px to 0px and the opacity from 0 to 1. This can easily be done by modifying style from the example above like so:
    
+
      style={{
+    opacity: this.state.fadeAnim, // Binds directly
+    transform: [{
+      translateY: this.state.fadeAnim.interpolate({
+        inputRange: [0, 1],
+        outputRange: [150, 0]  // 0 : 150, 0.5 : 75, 1 : 0
+      }),
+    }],
+  }}
+
    
+
    interpolate() supports multiple range segments as well, which is handy for defining dead zones and other handy tricks. For example, to get a negation relationship at -300 that goes to 0 at -100, then back up to 1 at 0, and then back down to zero at 100 followed by a dead-zone that remains at 0 for everything beyond that, you could do:
    
+
    value.interpolate({
+  inputRange: [-300, -100, 0, 100, 101],
+  outputRange: [300, 0, 1, 0, 0],
+});
+
    
+
    Which would map like so:
    
+
    Input | Output
+------|-------
+  -400|    450
+  -300|    300
+  -200|    150
+  -100|      0
+   -50|    0.5
+     0|      1
+    50|    0.5
+   100|      0
+   101|      0
+   200|      0
+
    
+
    interpolate() also supports mapping to strings, allowing you to animate colors as well as values with units. For example, if you wanted to animate a rotation you could do:
    
+
    value.interpolate({
+  inputRange: [0, 360],
+  outputRange: ['0deg', '360deg'],
+});
+
    
+
    interpolate() also supports arbitrary easing functions, many of which are already implemented in the Easing module. interpolate() also has configurable behavior for extrapolating the outputRange. You can set the extrapolation by setting the extrapolate, extrapolateLeft, or extrapolateRight options. The default value is extend but you can use clamp to prevent the output value from exceeding outputRange.
    
+
    Tracking dynamic values
    
+
    Animated values can also track other values. Just set the toValue of an animation to another animated value instead of a plain number. For example, a "Chat Heads" animation like the one used by Messenger on Android could be implemented with a spring() pinned on another animated value, or with timing() and a duration of 0 for rigid tracking. They can also be composed with interpolations:
    
+
    Animated.spring(follower, {toValue: leader}).start();
+Animated.timing(opacity, {
+  toValue: pan.x.interpolate({
+    inputRange: [0, 300],
+    outputRange: [1, 0],
+  }),
+}).start();
+
    
+
    The leader and follower animated values would be implemented using Animated.ValueXY(). ValueXY is a handy way to deal with 2D interactions, such as panning or dragging. It is a simple wrapper that basically contains two Animated.Value instances and some helper functions that call through to them, making ValueXY a drop-in replacement for Value in many cases. It allows us to track both x and y values in the example above.
    
+
    Tracking gestures
    
+
    Gestures, like panning or scrolling, and other events can map directly to animated values using Animated.event. This is done with a structured map syntax so that values can be extracted from complex event objects. The first level is an array to allow mapping across multiple args, and that array contains nested objects.
    
+
    For example, when working with horizontal scrolling gestures, you would do the following in order to map event.nativeEvent.contentOffset.x to scrollX (an Animated.Value):
    
+
     onScroll={Animated.event(
+   // scrollX = e.nativeEvent.contentOffset.x
+   [{ nativeEvent: {
+        contentOffset: {
+          x: scrollX
+        }
+      }
+    }]
+ )}
+
    
+
    When using PanResponder, you could use the following code to extract the x and y positions from gestureState.dx and gestureState.dy. We use a null in the first position of the array, as we are only interested in the second argument passed to the PanResponder handler, which is the gestureState.
    
+
    onPanResponderMove={Animated.event(
+  [null, // ignore the native event
+  // extract dx and dy from gestureState
+  // like 'pan.x = gestureState.dx, pan.y = gestureState.dy'
+  {dx: pan.x, dy: pan.y}
+])}
+
    
+
    Responding to the current animation value
    
+
    You may notice that there is no obvious way to read the current value while animating. This is because the value may only be known in the native runtime due to optimizations. If you need to run JavaScript in response to the current value, there are two approaches:
    
+
      
+
    • spring.stopAnimation(callback) will stop the animation and invoke callback with the final value. This is useful when making gesture transitions.
      • 
+
    • spring.addListener(callback) will invoke callback asynchronously while the animation is running, providing a recent value. This is useful for triggering state changes, for example snapping a bobble to a new option as the user drags it closer, because these larger state changes are less sensitive to a few frames of lag compared to continuous gestures like panning which need to run at 60 fps.
      • 
+
    
+
    Animated is designed to be fully serializable so that animations can be run in a high performance way, independent of the normal JavaScript event loop. This does influence the API, so keep that in mind when it seems a little trickier to do something compared to a fully synchronous system. Check out Animated.Value.addListener as a way to work around some of these limitations, but use it sparingly since it might have performance implications in the future.
    
+
    Using the native driver
    
+
    The Animated API is designed to be serializable. By using the native driver, we send everything about the animation to native before starting the animation, allowing native code to perform the animation on the UI thread without having to go through the bridge on every frame. Once the animation has started, the JS thread can be blocked without affecting the animation.
    
+
    Using the native driver for normal animations is quite simple. Just add useNativeDriver: true to the animation config when starting it.
    
+
    Animated.timing(this.state.animatedValue, {
+  toValue: 1,
+  duration: 500,
+  useNativeDriver: true, // <-- Add this
+}).start();
+
    
+
    Animated values are only compatible with one driver so if you use native driver when starting an animation on a value, make sure every animation on that value also uses the native driver.
    
+
    The native driver also works with Animated.event. This is especially useful for animations that follow the scroll position as without the native driver, the animation will always run a frame behind the gesture due to the async nature of React Native.
    
+
    <Animated.ScrollView // <-- Use the Animated ScrollView wrapper
+  scrollEventThrottle={1} // <-- Use 1 here to make sure no events are ever missed
+  onScroll={Animated.event(
+    [
+      {
+        nativeEvent: {
+          contentOffset: {y: this.state.animatedValue},
+        },
+      },
+    ],
+    {useNativeDriver: true}, // <-- Add this
+  )}>
+  {content}
+</Animated.ScrollView>
+
    
+
    You can see the native driver in action by running the RNTester app, then loading the Native Animated Example. You can also take a look at the source code to learn how these examples were produced.
    
+
    Caveats
    
+
    Not everything you can do with Animated is currently supported by the native driver. The main limitation is that you can only animate non-layout properties: things like transform and opacity will work, but flexbox and position properties will not. When using Animated.event, it will only work with direct events and not bubbling events. This means it does not work with PanResponder but does work with things like ScrollView#onScroll.
    
+
    When an animation is running, it can prevent VirtualizedList components from rendering more rows. If you need to run a long or looping animation while the user is scrolling through a list, you can use isInteraction: false in your animation's config to prevent this issue.
    
+
    Bear in mind
    
+
    While using transform styles such as rotateY, rotateX, and others ensure the transform style perspective is in place. At this time some animations may not render on Android without it. Example below.
    
+
    <Animated.View
+  style={{
+    transform: [
+      {scale: this.state.scale},
+      {rotateY: this.state.rotateY},
+      {perspective: 1000}, // without this line this Animation will not render on Android while working fine on iOS
+    ],
+  }}
+/>
+
    
+
    Additional examples
    
+
    The RNTester app has various examples of Animated in use:
    
+
+
    LayoutAnimation API
    
+
    LayoutAnimation allows you to globally configure create and update animations that will be used for all views in the next render/layout cycle. This is useful for doing flexbox layout updates without bothering to measure or calculate specific properties in order to animate them directly, and is especially useful when layout changes may affect ancestors, for example a "see more" expansion that also increases the size of the parent and pushes down the row below which would otherwise require explicit coordination between the components in order to animate them all in sync.
    
+
    Note that although LayoutAnimation is very powerful and can be quite useful, it provides much less control than Animated and other animation libraries, so you may need to use another approach if you can't get LayoutAnimation to do what you want.
    
+
    Note that in order to get this to work on Android you need to set the following flags via UIManager:
    
+
    UIManager.setLayoutAnimationEnabledExperimental &&
+  UIManager.setLayoutAnimationEnabledExperimental(true);
+
    
+
    This example uses a preset value, you can customize the animations as you need, see LayoutAnimation.js for more information.
    
+
    Additional notes
    
+
    requestAnimationFrame
    
+
    requestAnimationFrame is a polyfill from the browser that you might be familiar with. It accepts a function as its only argument and calls that function before the next repaint. It is an essential building block for animations that underlies all of the JavaScript-based animation APIs. In general, you shouldn't need to call this yourself - the animation APIs will manage frame updates for you.
    
+
    setNativeProps
    
+
    As mentioned in the Direct Manipulation section, setNativeProps allows us to modify properties of native-backed components (components that are actually backed by native views, unlike composite components) directly, without having to setState and re-render the component hierarchy.
    
+
    We could use this in the Rebound example to update the scale - this might be helpful if the component that we are updating is deeply nested and hasn't been optimized with shouldComponentUpdate.
    
+
    If you find your animations with dropping frames (performing below 60 frames per second), look into using setNativeProps or shouldComponentUpdate to optimize them. Or you could run the animations on the UI thread rather than the JavaScript thread with the useNativeDriver option. You may also want to defer any computationally intensive work until after animations are complete, using the InteractionManager. You can monitor the frame rate by using the In-App Developer Menu "FPS Monitor" tool.

    App Extensions
    App extensions let you provide custom functionality and content outside of your main app. There are different types of app extensions on iOS, and they are all covered in the App Extension Programming Guide. In this guide, we'll briefly cover how you may take advantage of app extensions on iOS.
    
+
    Memory use in extensions
    
+
    As these extensions are loaded outside of the regular app sandbox, it's highly likely that several of these app extensions will be loaded simultaneously. As you might expect, these extensions have small memory usage limits. Keep these in mind when developing your app extensions. It's always highly recommended to test your application on an actual device, and more so when developing app extensions: too frequently, developers find that their extension works just fine in the iOS Simulator, only to get user reports that their extension is not loading on actual devices.
    
+
    We highly recommend that you watch Conrad Kramer's talk on Memory Use in Extensions to learn more about this topic.
    
+
    Today widget
    
+
    The memory limit of a Today widget is 16 MB. As it happens, Today widget implementations using React Native may work unreliably because the memory usage tends to be too high. You can tell if your Today widget is exceeding the memory limit if it yields the message 'Unable to Load':
    
+
    
+
    Always make sure to test your app extensions in a real device, but be aware that this may not be sufficient, especially when dealing with Today widgets. Debug-configured builds are more likely to exceed the memory limits, while release-configured builds don't fail right away. We highly recommend that you use Xcode's Instruments to analyze your real world memory usage, as it's very likely that your release-configured build is very close to the 16 MB limit. In situations like these, it is easy to go over the 16 MB limit by performing common operations, such as fetching data from an API.
    
+
    To experiment with the limits of React Native Today widget implementations, try extending the example project in react-native-today-widget.
    
+
    Other app extensions
    
+
    Other types of app extensions have greater memory limits than the Today widget. For instance, Custom Keyboard extensions are limited to 48 MB, and Share extensions are limited to 120 MB. Implementing such app extensions with React Native is more viable. One proof of concept example is react-native-ios-share-extension.

    Edit
    AppState
    AppState can tell you if the app is in the foreground or background, and notify you when the state changes.
    
+
    AppState is frequently used to determine the intent and proper behavior when handling push notifications.
    
+
    App States
    
+
      
+
    • active - The app is running in the foreground
      • 
+
    • background - The app is running in the background. The user is either:
+
        
+
      • in another app
        • 
+
      • on the home screen
        • 
+
      • [Android] on another Activity (even if it was launched by your app)
        • 
+
      • 
+
    • inactive - This is a state that occurs when transitioning between foreground & background, and during periods of inactivity such as entering the Multitasking view or in the event of an incoming call
      • 
+
    
+
    For more information, see Apple's documentation
    
+
    Basic Usage
    
+
    To see the current state, you can check AppState.currentState, which will be kept up-to-date. However, currentState will be null at launch while AppState retrieves it over the bridge.
    
+
    import React, {Component} from 'react';
+import {AppState, Text} from 'react-native';
+
+class AppStateExample extends Component {
+  state = {
+    appState: AppState.currentState,
+  };
+
+  componentDidMount() {
+    AppState.addEventListener('change', this._handleAppStateChange);
+  }
+
+  componentWillUnmount() {
+    AppState.removeEventListener('change', this._handleAppStateChange);
+  }
+
+  _handleAppStateChange = (nextAppState) => {
+    if (
+      this.state.appState.match(/inactive|background/) &&
+      nextAppState === 'active'
+    ) {
+      console.log('App has come to the foreground!');
+    }
+    this.setState({appState: nextAppState});
+  };
+
+  render() {
+    return <Text>Current state is: {this.state.appState}</Text>;
+  }
+}
+
    
+
    This example will only ever appear to say "Current state is: active" because the app is only visible to the user when in the active state, and the null state will happen only momentarily.

That will be a breaking change though, as both the method and event names are different (addListener events are currently required to be globally unique).

+AsyncStorage · React Native
    0.58
    Edit
    AsyncStorage
    AsyncStorage is a simple, unencrypted, asynchronous, persistent, key-value storage system that is global to the app. It should be used instead of LocalStorage.
    
+
    It is recommended that you use an abstraction on top of AsyncStorage instead of AsyncStorage directly for anything more than light usage since it operates globally.
    
+
    On iOS, AsyncStorage is backed by native code that stores small values in a serialized dictionary and larger values in separate files. On Android, AsyncStorage will use either RocksDB or SQLite based on what is available.
    
+
    The AsyncStorage JavaScript code is a simple facade that provides a clear JavaScript API, real Error objects, and simple non-multi functions. Each method in the API returns a Promise object.
    
+
    Importing the AsyncStorage library:
    
+
    import {AsyncStorage} from 'react-native';
+
    
+
    Persisting data:
    
+
    _storeData = async () => {
+  try {
+    await AsyncStorage.setItem('@MySuperStore:key', 'I like to save it.');
+  } catch (error) {
+    // Error saving data
+  }
+};
+
    
+
    Fetching data:
    
+
    _retrieveData = async () => {
+  try {
+    const value = await AsyncStorage.getItem('TASKS');
+    if (value !== null) {
+      // We have data!!
+      console.log(value);
+    }
+  } catch (error) {
+    // Error retrieving data
+  }
+};
+
    
+
    Methods

+
    static mergeItem(key: string, value: string, [callback]: ?(error: ?Error) => void)
+
    
+
    Merges an existing key value with an input value, assuming both values are stringified JSON. Returns a Promise object.
    
+
    NOTE: This is not supported by all native implementations.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    keystringYesKey of the item to modify.

    callback?(error: ?Error) => voidNoFunction that will be called with any error.
    
+
    Example:
    
+
    let UID123_object = {
+  name: 'Chris',
+  age: 30,
+  traits: {hair: 'brown', eyes: 'brown'},
+};
+// You only need to define what will be added or updated
+let UID123_delta = {
+  age: 31,
+  traits: {eyes: 'blue', shoe_size: 10},
+};
+
+AsyncStorage.setItem('UID123', JSON.stringify(UID123_object), () => {
+  AsyncStorage.mergeItem('UID123', JSON.stringify(UID123_delta), () => {
+    AsyncStorage.getItem('UID123', (err, result) => {
+      console.log(result);
+    });
+  });
+});
+
+// Console log result:
+// => {'name':'Chris','age':31,'traits':
+//    {'shoe_size':10,'hair':'brown','eyes':'blue'}}
+
    
+
    
+
    clear()
    
+
    static clear([callback]: ?(error: ?Error) => void)
+
    
+
    Erases all AsyncStorage for all clients, libraries, etc. You probably don't want to call this; use removeItem or multiRemove to clear only your app's keys. Returns a Promise object.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    callback?(error: ?Error) => voidNoFunction that will be called with any error.
    
+
    
+
    getAllKeys()
    
+
    static getAllKeys([callback]: ?(error: ?Error, keys: ?Array<string>) => void)
+

+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    callback?(error: ?Error, keys: ?Array) => voidNoFunction that will be called with all keys found and any error.
    
+
    
+
    flushGetRequests()
    
+
    static flushGetRequests(): [object Object]
+
    
+
    Flushes any pending requests using a single batch call to get the data.
    
+
    
+
    multiGet()
    
+
    static multiGet(keys: Array<string>, [callback]: ?(errors: ?Array<Error>, result: ?Array<Array<string>>) => void)
+
    
+
    This allows you to batch the fetching of items given an array of key inputs. Your callback will be invoked with an array of corresponding key-value pairs found:
    
+
    multiGet(['k1', 'k2'], cb) -> cb([['k1', 'val1'], ['k2', 'val2']])
+
    
+
    The method returns a Promise object.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    keysArrayYesArray of key for the items to get.

+
    Example:
    
+
    AsyncStorage.getAllKeys((err, keys) => {
+  AsyncStorage.multiGet(keys, (err, stores) => {
+    stores.map((result, i, store) => {

+      let key = store[i][0];
+      let value = store[i][1];
+    });
+  });
+});
+
    
+
    
+
    multiSet()
    
+
    static multiSet(keyValuePairs: Array<Array<string>>, [callback]: ?(errors: ?Array<Error>) => void)
+
    
+
    Use this as a batch operation for storing multiple key-value pairs. When the operation completes you'll get a single callback with any errors:
    
+
    multiSet([['k1', 'val1'], ['k2', 'val2']], cb);
+
    
+
    The method returns a Promise object.

+AsyncStorage.multiRemove(keys, (err) => {
+  // keys k1 & k2 removed, if they existed
+  // do most stuff after removal (if you want)
+});
+
    
+
    
+
    multiMerge()

+
+
+
+
+
+
+
+

+
    
+
    getAllKeys()
    
+
    static getAllKeys([callback]: ?(error: ?Error, keys: ?Array<string>) => void)
+
    
+
    Gets all keys known to your app; for all callers, libraries, etc. Returns a Promise object.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    callback?(error: ?Error, keys: ?Array) => voidNoFunction that will be called with all keys found and any error.
    
+
    
+
    flushGetRequests()
    
+
    static flushGetRequests(): [object Object]
+
    
+
    Flushes any pending requests using a single batch call to get the data.
    
+
    
+
    multiGet()
    
+
    static multiGet(keys: Array<string>, [callback]: ?(errors: ?Array<Error>, result: ?Array<Array<string>>) => void)
+
    
+
    This allows you to batch the fetching of items given an array of key inputs. Your callback will be invoked with an array of corresponding key-value pairs found:
    
+
    multiGet(['k1', 'k2'], cb) -> cb([['k1', 'val1'], ['k2', 'val2']])
+
    
+
    The method returns a Promise object.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    keysArrayYesArray of key for the items to get.
    callback?(errors: ?Array, result: ?Array<Array>) => voidNoFunction that will be called with a key-value array of the results, plus an array of any key-specific errors found.
    
+
    Example:
    
+
    AsyncStorage.getAllKeys((err, keys) => {
+  AsyncStorage.multiGet(keys, (err, stores) => {
+    stores.map((result, i, store) => {
+      // get at each store's key/value so you can work with it
+      let key = store[i][0];
+      let value = store[i][1];
+    });
+  });
+});
+
    
+
    
+
    multiSet()
    
+
    static multiSet(keyValuePairs: Array<Array<string>>, [callback]: ?(errors: ?Array<Error>) => void)
+
    
+
    Use this as a batch operation for storing multiple key-value pairs. When the operation completes you'll get a single callback with any errors:
    
+
    multiSet([['k1', 'val1'], ['k2', 'val2']], cb);
+
    
+
    The method returns a Promise object.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription

    Example:
    
+
    let keys = ['k1', 'k2'];
+AsyncStorage.multiRemove(keys, (err) => {
+  // keys k1 & k2 removed, if they existed
+  // do most stuff after removal (if you want)
+});
+
    
+
    
+
    multiMerge()
    
+
    static multiMerge(keyValuePairs: Array<Array<string>>, [callback]: ?(errors: ?Array<Error>) => void)
+
    
+
    Batch operation to merge in existing and new values for a given set of keys. This assumes that the values are stringified JSON. Returns a Promise object.

+  age: 26,
+  traits: {eyes: 'green', shoe_size: 6},
+};
+
+let multi_set_pairs = [

    BackHandler
    Detect hardware button presses for back navigation.
    
+
    Android: Detect hardware back button presses, and programmatically invoke the default back button functionality to exit the app if there are no listeners or if none of the listeners return true.
    
+
    tvOS: Detect presses of the menu button on the TV remote. (Still to be implemented: programmatically disable menu button handling functionality to exit the app if there are no listeners or if none of the listeners return true.)
    
+
    iOS: Not applicable.
    
+
    The event subscriptions are called in reverse order (i.e. last registered subscription first), and if one subscription returns true then subscriptions registered earlier will not be called.
    
+
    Example:
    
+
    BackHandler.addEventListener('hardwareBackPress', function() {
+  // this.onMainScreen and this.goBack are just examples, you need to use your own implementation here
+  // Typically you would use the navigator here to go to the last state.

+Building For TV Devices · React Native

    Edit
    Building For TV Devices
    
+
    TV devices support has been implemented with the intention of making existing React Native applications "just work" on Apple TV and Android TV, with few or no changes needed in the JavaScript code for the applications.
    
+
    
+  
      
+    
+    
+  
    
+
    
+
    
+
    The RNTester app supports Apple TV; use the RNTester-tvOS build target to build for tvOS.
    
+
    Build changes
    
+
      
+
    • Native layer: React Native Xcode projects all now have Apple TV build targets, with names ending in the string '-tvOS'.
      • 
+
    • react-native init: New React Native projects created with react-native init will have Apple TV target automatically created in their XCode projects.
      • 
+
    • JavaScript layer: Support for Apple TV has been added to Platform.ios.js. You can check whether code is running on AppleTV by doing
      • 
+
    
+
    var Platform = require('Platform');
+var running_on_tv = Platform.isTV;
+
+// If you want to be more specific and only detect devices running tvOS
+// (but no Android TV devices) you can use:
+var running_on_apple_tv = Platform.isTVOS;
+
    
+
    
+
    Build changes
    
+
      
+
    • Native layer: To run React Native project on Android TV make sure to make the following changes to AndroidManifest.xml
      • 
+
    
+
      <!-- Add custom banner image to display as Android TV launcher icon -->
+ <application
+  ...
+  android:banner="@drawable/tv_banner"
+  >
+    ...
+    <intent-filter>
+      ...
+      <!-- Needed to properly create a launch intent when running on Android TV -->
+      <category android:name="android.intent.category.LEANBACK_LAUNCHER"/>
+    </intent-filter>
+    ...
+  </application>
+
    
+
      
+
    • JavaScript layer: Support for Android TV has been added to Platform.android.js. You can check whether code is running on Android TV by doing
      • 
+
    
+
    var Platform = require('Platform');
+var running_on_android_tv = Platform.isTV;
+
    
+
    
+
    Code changes
    
+
    
+
      
+
    • General support for tvOS: Apple TV specific changes in native code are all wrapped by the TARGET_OS_TV define. These include changes to suppress APIs that are not supported on tvOS (e.g. web views, sliders, switches, status bar, etc.), and changes to support user input from the TV remote or keyboard.
      • 
+
    • Common codebase: Since tvOS and iOS share most Objective-C and JavaScript code in common, most documentation for iOS applies equally to tvOS.
      • 
+
    • Access to touchable controls: When running on Apple TV, the native view class is RCTTVView, which has additional methods to make use of the tvOS focus engine. The Touchable mixin has code added to detect focus changes and use existing methods to style the components properly and initiate the proper actions when the view is selected using the TV remote, so TouchableWithoutFeedback, TouchableHighlight and TouchableOpacity will "just work". In particular:
      
+
        
+
      • onFocus will be executed when the touchable view goes into focus
        • 
+
      • onBlur will be executed when the touchable view goes out of focus
        • 
+
      • onPress will be executed when the touchable view is actually selected by pressing the "select" button on the TV remote.
        • 
+
      • 
+
    
+
    
+
      
+
    • Access to touchable controls: When running on Android TV the Android framework will automatically apply a directional navigation scheme based on relative position of focusable elements in your views. The Touchable mixin has code added to detect focus changes and use existing methods to style the components properly and initiate the proper actions when the view is selected using the TV remote, so TouchableWithoutFeedback, TouchableHighlight, TouchableOpacity and TouchableNativeFeedback will "just work". In particular:
      
+
        
+
      • onFocus will be executed when the touchable view goes into focus
        • 
+
      • onBlur will be executed when the touchable view goes out of focus
        • 
+
      • onPress will be executed when the touchable view is actually selected by pressing the "select" button on the TV remote.
        • 
+
      • 
+
    
+
    
+
      
+
    • TV remote/keyboard input: A new native class, RCTTVRemoteHandler, sets up gesture recognizers for TV remote events. When TV remote events occur, this class fires notifications that are picked up by RCTTVNavigationEventEmitter (a subclass of RCTEventEmitter), that fires a JS event. This event will be picked up by instances of the TVEventHandler JavaScript object. Application code that needs to implement custom handling of TV remote events can create an instance of TVEventHandler and listen for these events, as in the following code:
      • 
+
    
+
    
+
      
+
    • TV remote/keyboard input: A new native class, ReactAndroidTVRootViewHelper, sets up key events handlers for TV remote events. When TV remote events occur, this class fires a JS event. This event will be picked up by instances of the TVEventHandler JavaScript object. Application code that needs to implement custom handling of TV remote events can create an instance of TVEventHandler and listen for these events, as in the following code:
      • 
+
    
+
    
+
    var TVEventHandler = require('TVEventHandler');
+
+class Game2048 extends React.Component {
+  _tvEventHandler: any;
+
+  _enableTVEventHandler() {

    • Dev Menu support: On the simulator, cmd-D will bring up the developer menu, just like on iOS. To bring it up on a real Apple TV device, make a long press on the play/pause button on the remote. (Please do not shake the Apple TV device, that will not work :) )
      • 
+
    • TV remote animations: RCTTVView native code implements Apple-recommended parallax animations to help guide the eye as the user navigates through views. The animations can be disabled or adjusted with new optional view properties.
      • 
+
    • Back navigation with the TV remote menu button: The BackHandler component, originally written to support the Android back button, now also supports back navigation on the Apple TV using the menu button on the TV remote.
      • 
+
    • TabBarIOS behavior: The TabBarIOS component wraps the native UITabBar API, which works differently on Apple TV. To avoid jittery rerendering of the tab bar in tvOS (see this issue), the selected tab bar item can only be set from Javascript on initial render, and is controlled after that by the user through native code.

    Building For TV Devices
    
+
    TV devices support has been implemented with the intention of making existing React Native applications "just work" on Apple TV and Android TV, with few or no changes needed in the JavaScript code for the applications.
    
+
    
+  
      
+    
+    
+  
    
+
    
+
    
+
    The RNTester app supports Apple TV; use the RNTester-tvOS build target to build for tvOS.
    
+
    Build changes
    
+
      
+
    • Native layer: React Native Xcode projects all now have Apple TV build targets, with names ending in the string '-tvOS'.
      • 
+
    • react-native init: New React Native projects created with react-native init will have Apple TV target automatically created in their XCode projects.
      • 
+
    • JavaScript layer: Support for Apple TV has been added to Platform.ios.js. You can check whether code is running on AppleTV by doing
      • 
+
    
+
    var Platform = require('Platform');
+var running_on_tv = Platform.isTV;
+
+// If you want to be more specific and only detect devices running tvOS
+// (but no Android TV devices) you can use:
+var running_on_apple_tv = Platform.isTVOS;
+
    
+
    
+
    Build changes
    
+
      
+
    • Native layer: To run React Native project on Android TV make sure to make the following changes to AndroidManifest.xml
      • 
+
    
+
      <!-- Add custom banner image to display as Android TV launcher icon -->
+ <application
+  ...
+  android:banner="@drawable/tv_banner"
+  >
+    ...
+    <intent-filter>
+      ...
+      <!-- Needed to properly create a launch intent when running on Android TV -->
+      <category android:name="android.intent.category.LEANBACK_LAUNCHER"/>
+    </intent-filter>
+    ...
+  </application>
+
    
+
      
+
    • JavaScript layer: Support for Android TV has been added to Platform.android.js. You can check whether code is running on Android TV by doing
      • 
+
    
+
    var Platform = require('Platform');
+var running_on_android_tv = Platform.isTV;
+
    
+
    
+
    Code changes
    
+
    
+
      
+
    • General support for tvOS: Apple TV specific changes in native code are all wrapped by the TARGET_OS_TV define. These include changes to suppress APIs that are not supported on tvOS (e.g. web views, sliders, switches, status bar, etc.), and changes to support user input from the TV remote or keyboard.
      • 
+
    • Common codebase: Since tvOS and iOS share most Objective-C and JavaScript code in common, most documentation for iOS applies equally to tvOS.
      • 
+
    • Access to touchable controls: When running on Apple TV, the native view class is RCTTVView, which has additional methods to make use of the tvOS focus engine. The Touchable mixin has code added to detect focus changes and use existing methods to style the components properly and initiate the proper actions when the view is selected using the TV remote, so TouchableWithoutFeedback, TouchableHighlight and TouchableOpacity will "just work". In particular:
      
+
        
+
      • onFocus will be executed when the touchable view goes into focus
        • 
+
      • onBlur will be executed when the touchable view goes out of focus
        • 
+
      • onPress will be executed when the touchable view is actually selected by pressing the "select" button on the TV remote.
        • 
+
      • 
+
    
+
    
+
      
+
    • Access to touchable controls: When running on Android TV the Android framework will automatically apply a directional navigation scheme based on relative position of focusable elements in your views. The Touchable mixin has code added to detect focus changes and use existing methods to style the components properly and initiate the proper actions when the view is selected using the TV remote, so TouchableWithoutFeedback, TouchableHighlight, TouchableOpacity and TouchableNativeFeedback will "just work". In particular:
      
+
        
+
      • onFocus will be executed when the touchable view goes into focus
        • 
+
      • onBlur will be executed when the touchable view goes out of focus
        • 
+
      • onPress will be executed when the touchable view is actually selected by pressing the "select" button on the TV remote.
        • 
+
      • 
+
    
+
    
+
      
+
    • TV remote/keyboard input: A new native class, RCTTVRemoteHandler, sets up gesture recognizers for TV remote events. When TV remote events occur, this class fires notifications that are picked up by RCTTVNavigationEventEmitter (a subclass of RCTEventEmitter), that fires a JS event. This event will be picked up by instances of the TVEventHandler JavaScript object. Application code that needs to implement custom handling of TV remote events can create an instance of TVEventHandler and listen for these events, as in the following code:
      • 
+
    
+
    
+
      
+
    • TV remote/keyboard input: A new native class, ReactAndroidTVRootViewHelper, sets up key events handlers for TV remote events. When TV remote events occur, this class fires a JS event. This event will be picked up by instances of the TVEventHandler JavaScript object. Application code that needs to implement custom handling of TV remote events can create an instance of TVEventHandler and listen for these events, as in the following code:
      • 
+
    
+
    
+
    var TVEventHandler = require('TVEventHandler');
+
+class Game2048 extends React.Component {
+  _tvEventHandler: any;
+
+  _enableTVEventHandler() {
+    this._tvEventHandler = new TVEventHandler();
+    this._tvEventHandler.enable(this, function(cmp, evt) {
+      if (evt && evt.eventType === 'right') {
+        cmp.setState({board: cmp.state.board.move(2)});
+      } else if(evt && evt.eventType === 'up') {
+        cmp.setState({board: cmp.state.board.move(1)});
+      } else if(evt && evt.eventType === 'left') {

+    this._enableTVEventHandler();

    Building React Native from source
    You will need to build React Native from source if you want to work on a new feature/bug fix, try out the latest features which are not released yet, or maintain your own fork with patches that cannot be merged to the core.
    
+
    Android
    
+
    Prerequisites
    
+
    Assuming you have the Android SDK installed, run android to open the Android SDK Manager.
    
+
    Make sure you have the following installed:
    
+
      
+
    1. Android SDK version 28 (compileSdkVersion in build.gradle)
      2. 
+
    2. SDK build tools version 28.0.3 (buildToolsVersion in build.gradle)
      3. 
+
    3. Android Support Repository >= 28 (for Android Support Library)
      4. 
+
    4. Android NDK (download links and installation instructions below)
      5. 
+
    
+
    Point Gradle to your Android SDK:
    
+
    Step 1: Set environment variables through your local shell.
    
+
    Note: Files may vary based on shell flavor. See below for examples from common shells.
    
+
      
+
    • bash: .bash_profile or .bashrc
      • 
+
    • zsh: .zprofile or .zshrc
      • 
+
    • ksh: .profile or $ENV
      • 
+
    
+
    Example:
    
+
    export ANDROID_SDK=/Users/your_unix_name/android-sdk-macosx
+export ANDROID_NDK=/Users/your_unix_name/android-ndk/android-ndk-r17c
+
    
+
    Step 2: Create a local.properties file in the android directory of your react-native app with the following contents:
    
+
    Example:
    
+
    sdk.dir=/Users/your_unix_name/android-sdk-macosx
+ndk.dir=/Users/your_unix_name/android-ndk/android-ndk-r17c
+
    
+
    Download links for Android NDK
    
+
      
+
    1. Mac OS (64-bit) - http://dl.google.com/android/repository/android-ndk-r17c-darwin-x86_64.zip
      2. 
+
    2. Linux (64-bit) - http://dl.google.com/android/repository/android-ndk-r17c-linux-x86_64.zip
      3. 
+
    3. Windows (64-bit) - http://dl.google.com/android/repository/android-ndk-r17c-windows-x86_64.zip
      4. 
+
    4. Windows (32-bit) - http://dl.google.com/android/repository/android-ndk-r17c-windows-x86.zip
      5. 
+
    
+
    You can find further instructions on the official page.
    
+
    Building the source
    
+
    1. Installing the fork
    
+
    First, you need to install react-native from your fork. For example, to install the master branch from the official repo, run the following:
    
+
    npm install --save github:facebook/react-native#master
+
    
+
    Alternatively, you can clone the repo to your node_modules directory and run npm install inside the cloned repo.
    
+
    2. Adding gradle dependencies
    
+
    Add gradle-download-task as dependency in android/build.gradle:
    
+
    ...
+    dependencies {
+        classpath 'com.android.tools.build:gradle:3.2.1'
+        classpath 'de.undercouch:gradle-download-task:3.4.3'
+
+        // NOTE: Do not place your application dependencies here; they belong
+        // in the individual module build.gradle files
+    }
+...
+
    
+
    3. Adding the :ReactAndroid project
    
+
    Add the :ReactAndroid project in android/settings.gradle:
    
+
    ...
+include ':ReactAndroid'
+
+project(':ReactAndroid').projectDir = new File(
+    rootProject.projectDir, '../node_modules/react-native/ReactAndroid')
+...
+
    
+
    Modify your android/app/build.gradle to use the :ReactAndroid project instead of the pre-compiled library, e.g. - replace implementation 'com.facebook.react:react-native:+' with implementation project(':ReactAndroid'):
    
+
    ...
+dependencies {
+    implementation fileTree(dir: 'libs', include: ['*.jar'])
+    implementation 'com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}'
+
+    implementation project(':ReactAndroid')
+
+    ...
+}
+...
+
    
+
    4. Making 3rd-party modules use your fork
    
+
    If you use 3rd-party React Native modules, you need to override their dependencies so that they don't bundle the pre-compiled library. Otherwise you'll get an error while compiling - Error: more than one library with package name 'com.facebook.react'.
    
+
    Modify your android/app/build.gradle, and add:
    
+
    configurations.all {
+    exclude group: 'com.facebook.react', module: 'react-native'
+}
+
    
+
    Building from Android Studio
    
+
    From the Welcome screen of Android Studio choose "Import project" and select the android folder of your app.
    
+
    You should be able to use the Run button to run your app on a device. Android Studio won't start the packager automatically, you'll need to start it by running npm start on the command line.
    
+
    Additional notes
    
+
    Building from source can take a long time, especially for the first build, as it needs to download ~200 MB of artifacts and compile the native code. Every time you update the react-native version from your repo, the build directory may get deleted, and all the files are re-downloaded. To avoid this, you might want to change your build directory path by editing the ~/.gradle/init.gradle file:
    
+
    gradle.projectsLoaded {
+    rootProject.allprojects {
+        buildDir = "/path/to/build/directory/${rootProject.name}/${project.name}"
+    }
+}
+
    
+
    Troubleshooting
    
+
    Gradle build fails in ndk-build. See the section about local.properties file above.
    
+
    Testing your Changes
    
+
    If you made changes to React Native and submit a pull request, all tests will run on your pull request automatically. To run the tests locally, see Testing your Changes.
    
+
    Making your changes available
    
+
    See the Publishing your own version of react native for several options to make your changes available for your and other app projects.

+project(':ReactAndroid').projectDir = new File(
+    rootProject.projectDir, '../node_modules/react-native/ReactAndroid')
+...
+
    
+
    Modify your android/app/build.gradle to use the :ReactAndroid project instead of the pre-compiled library, e.g. - replace implementation 'com.facebook.react:react-native:+' with implementation project(':ReactAndroid'):
    
+
    ...
+dependencies {
+    implementation fileTree(dir: 'libs', include: ['*.jar'])
+    implementation 'com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}'
+
+    implementation project(':ReactAndroid')
+
+    ...
+}
+...
+
    
+
    4. Making 3rd-party modules use your fork
    
+
    If you use 3rd-party React Native modules, you need to override their dependencies so that they don't bundle the pre-compiled library. Otherwise you'll get an error while compiling - Error: more than one library with package name 'com.facebook.react'.
    
+
    Modify your android/app/build.gradle, and add:
    
+
    configurations.all {
+    exclude group: 'com.facebook.react', module: 'react-native'
+}
+
    
+
    Building from Android Studio
    
+
    From the Welcome screen of Android Studio choose "Import project" and select the android folder of your app.
    
+
    You should be able to use the Run button to run your app on a device. Android Studio won't start the packager automatically, you'll need to start it by running npm start on the command line.
    
+
    Additional notes
    
+
    Building from source can take a long time, especially for the first build, as it needs to download ~200 MB of artifacts and compile the native code. Every time you update the react-native version from your repo, the build directory may get deleted, and all the files are re-downloaded. To avoid this, you might want to change your build directory path by editing the ~/.gradle/init.gradle file:
    
+
    gradle.projectsLoaded {
+    rootProject.allprojects {
+        buildDir = "/path/to/build/directory/${rootProject.name}/${project.name}"
+    }
+}
+
    
+
    Troubleshooting
    
+
    Gradle build fails in ndk-build. See the section about local.properties file above.
    
+
    Testing your Changes
    
+
    If you made changes to React Native and submit a pull request, all tests will run on your pull request automatically. To run the tests locally, see Testing your Changes.
    
+
    Making your changes available
    
+
    See the Publishing your own version of react native for several options to make your changes available for your and other app projects.

+CameraRoll · React Native

    CameraRoll
    CameraRoll provides access to the local camera roll or photo library.
    
+
    On iOS, the CameraRoll API requires the RCTCameraRoll library to be linked. You can refer to Linking Libraries (iOS) to learn more.
    
+
    Permissions
    
+
    The user's permission is required in order to access the Camera Roll on devices running iOS 10 or later. Add the NSPhotoLibraryUsageDescription key in your Info.plist with a string that describes how your app will use this data. This key will appear as Privacy - Photo Library Usage Description in Xcode.
    
+
    If you are targeting devices running iOS 11 or later, you will also need to add the NSPhotoLibraryAddUsageDescription key in your Info.plist. Use this key to define a string that describes how your app will use this data. By adding this key to your Info.plist, you will be able to request write-only access permission from the user. If you try to save to the camera roll without this permission, your app will exit.

+
    Methods
    
+
    saveToCameraRoll()
    
+
    CameraRoll.saveToCameraRoll(tag, [type]);
+
    
+
    Saves the photo or video to the camera roll or photo library.
    
+
    On Android, the tag must be a local image or video URI, such as "file:///sdcard/img.png".
    
+
    On iOS, the tag can be any image URI (including local, remote asset-library and base64 data URIs) or a local video file URI (remote or data URIs are not supported for saving video at this time).
    
+
    If the tag has a file extension of .mov or .mp4, it will be inferred as a video. Otherwise it will be treated as a photo. To override the automatic choice, you can pass an optional type parameter that must be one of 'photo' or 'video'.
    
+
    Returns a Promise which will resolve with the new URI.
    
+
    Parameters:
    
+
+
+
+

    CheckBox
    Renders a boolean input (Android only).
    
+
    This is a controlled component that requires an onValueChange callback that updates the value prop in order for the component to reflect user actions. If the value prop is not updated, the component will continue to render the supplied value prop instead of the expected result of any user actions.

    Color Reference
    Components in React Native are styled using JavaScript. Color properties usually match how CSS works on the web.
    
+
    Red-green-blue
    
+
    React Native supports rgb() and rgba() in both hexadecimal and functional notation:
    
+
      
+
    • '#f0f' (#rgb)
      • 
+
    • '#ff00ff' (#rrggbb)
      • 
+
    • 'rgb(255, 0, 255)'
      • 
+
    • 'rgba(255, 255, 255, 1.0)'
      • 
+
    • '#f0ff' (#rgba)
      • 
+
    • '#ff00ff00' (#rrggbbaa)
      • 
+
    
+
    Hue-saturation-lightness
    
+
    hsl() and hsla() is supported in functional notation:
    
+
      
+
    • 'hsl(360, 100%, 100%)'
      • 
+
    • 'hsla(360, 100%, 100%, 1.0)'
      • 
+
    
+
    transparent
    
+
    This is a shortcut for rgba(0,0,0,0):
    
+
      
+
    • 'transparent'
      • 
+
    
+
    Named colors
    
+
    You can also use color names as values. React Native follows the CSS3 specification:
    
+
      
+

      •

    hsl() and hsla() is supported in functional notation:
    
+
      
+
    • 'hsl(360, 100%, 100%)'
      • 
+
    • 'hsla(360, 100%, 100%, 1.0)'
      •

    transparent

    This is a shortcut for rgba(0,0,0,0):

+
    • 'transparent'

    Communication between native and React Native
    In Integrating with Existing Apps guide and Native UI Components guide we learn how to embed React Native in a native component and vice versa. When we mix native and React Native components, we'll eventually find a need to communicate between these two worlds. Some ways to achieve that have been already mentioned in other guides. This article summarizes available techniques.
    
+
    Introduction
    
+
    React Native is inspired by React, so the basic idea of the information flow is similar. The flow in React is one-directional. We maintain a hierarchy of components, in which each component depends only on its parent and its own internal state. We do this with properties: data is passed from a parent to its children in a top-down manner. If an ancestor component relies on the state of its descendant, one should pass down a callback to be used by the descendant to update the ancestor.
    
+
    The same concept applies to React Native. As long as we are building our application purely within the framework, we can drive our app with properties and callbacks. But, when we mix React Native and native components, we need some special, cross-language mechanisms that would allow us to pass information between them.
    
+
    Properties
    
+
    Properties are the simplest way of cross-component communication. So we need a way to pass properties both from native to React Native, and from React Native to native.
    
+
    Passing properties from native to React Native
    
+
    You can pass properties down to the React Native app by providing a custom implementation of ReactActivityDelegate in your main activity. This implementation should override getLaunchOptions to return a Bundle with the desired properties.
    
+
    public class MainActivity extends ReactActivity {
+  @Override
+  protected ReactActivityDelegate createReactActivityDelegate() {
+    return new ReactActivityDelegate(this, getMainComponentName()) {
+      @Override
+      protected Bundle getLaunchOptions() {
+        Bundle initialProperties = new Bundle();
+        ArrayList<String> imageList = new ArrayList<String>(Arrays.asList(
+                "http://foo.com/bar1.png",
+                "http://foo.com/bar2.png"
+        ));
+        initialProperties.putStringArrayList("images", imageList);
+        return initialProperties;
+      }
+    };
+  }
+}
+
    
+
    import React from 'react';
+import {AppRegistry, View, Image} from 'react-native';
+
+class ImageBrowserApp extends React.Component {
+  renderImage(imgURI) {
+    return <Image source={{uri: imgURI}} />;
+  }
+  render() {
+    return <View>{this.props.images.map(this.renderImage)}</View>;
+  }
+}
+
+AppRegistry.registerComponent('AwesomeProject', () => ImageBrowserApp);
+
    
+
    ReactRootView provides a read-write property appProperties. After appProperties is set, the React Native app is re-rendered with new properties. The update is only performed when the new updated properties differ from the previous ones.
    
+
    Bundle updatedProps = mReactRootView.getAppProperties();
+ArrayList<String> imageList = new ArrayList<String>(Arrays.asList(
+        "http://foo.com/bar3.png",
+        "http://foo.com/bar4.png"
+));
+updatedProps.putStringArrayList("images", imageList);
+
+mReactRootView.setAppProperties(updatedProps);
+
    
+
    It is fine to update properties anytime. However, updates have to be performed on the main thread. You use the getter on any thread.
    
+
    There is no way to update only a few properties at a time. We suggest that you build it into your own wrapper instead.
    
+
    
+
    Note: Currently, JS functions componentWillReceiveProps and componentWillUpdateProps of the top level RN component will not be called after a prop update. However, you can access the new props in componentWillMount function.
    
+
    
+
    Passing properties from React Native to native
    
+
    The problem exposing properties of native components is covered in detail in this article. In short, properties that are to be reflected in JavaScript needs to be exposed as setter method annotated with @ReactProp, then just use them in React Native as if the component was an ordinary React Native component.
    
+
    Limits of properties
    
+
    The main drawback of cross-language properties is that they do not support callbacks, which would allow us to handle bottom-up data bindings. Imagine you have a small RN view that you want to be removed from the native parent view as a result of a JS action. There is no way to do that with props, as the information would need to go bottom-up.
    
+
    Although we have a flavor of cross-language callbacks (described here), these callbacks are not always the thing we need. The main problem is that they are not intended to be passed as properties. Rather, this mechanism allows us to trigger a native action from JS, and handle the result of that action in JS.
    
+
    Other ways of cross-language interaction (events and native modules)
    
+
    As stated in the previous chapter, using properties comes with some limitations. Sometimes properties are not enough to drive the logic of our app and we need a solution that gives more flexibility. This chapter covers other communication techniques available in React Native. They can be used for internal communication (between JS and native layers in RN) as well as for external communication (between RN and the 'pure native' part of your app).
    
+
    React Native enables you to perform cross-language function calls. You can execute custom native code from JS and vice versa. Unfortunately, depending on the side we are working on, we achieve the same goal in different ways. For native - we use events mechanism to schedule an execution of a handler function in JS, while for React Native we directly call methods exported by native modules.
    
+
    Calling React Native functions from native (events)
    
+
    Events are described in detail in this article. Note that using events gives us no guarantees about execution time, as the event is handled on a separate thread.
    
+
    Events are powerful, because they allow us to change React Native components without needing a reference to them. However, there are some pitfalls that you can fall into while using them:
    
+
      
+
    • As events can be sent from anywhere, they can introduce spaghetti-style dependencies into your project.
      • 
+
    • Events share namespace, which means that you may encounter some name collisions. Collisions will not be detected statically, which makes them hard to debug.
      • 
+
    • If you use several instances of the same React Native component and you want to distinguish them from the perspective of your event, you'll likely need to introduce identifiers and pass them along with events (you can use the native view's reactTag as an identifier).
      • 
+
    
+
    Calling native functions from React Native (native modules)
    
+
    Native modules are Java classes that are available in JS. Typically one instance of each module is created per JS bridge. They can export arbitrary functions and constants to React Native. They have been covered in detail in this article.
    
+
    
+
    Warning: All native modules share the same namespace. Watch out for name collisions when creating new ones.

    Communication between native and React Native
    In Integrating with Existing Apps guide and Native UI Components guide we learn how to embed React Native in a native component and vice versa. When we mix native and React Native components, we'll eventually find a need to communicate between these two worlds. Some ways to achieve that have been already mentioned in other guides. This article summarizes available techniques.
    
+
    Introduction
    
+
    React Native is inspired by React, so the basic idea of the information flow is similar. The flow in React is one-directional. We maintain a hierarchy of components, in which each component depends only on its parent and its own internal state. We do this with properties: data is passed from a parent to its children in a top-down manner. If an ancestor component relies on the state of its descendant, one should pass down a callback to be used by the descendant to update the ancestor.
    
+
    The same concept applies to React Native. As long as we are building our application purely within the framework, we can drive our app with properties and callbacks. But, when we mix React Native and native components, we need some special, cross-language mechanisms that would allow us to pass information between them.
    
+
    Properties
    
+
    Properties are the simplest way of cross-component communication. So we need a way to pass properties both from native to React Native, and from React Native to native.
    
+
    Passing properties from native to React Native
    
+
    In order to embed a React Native view in a native component, we use RCTRootView. RCTRootView is a UIView that holds a React Native app. It also provides an interface between native side and the hosted app.
    
+
    RCTRootView has an initializer that allows you to pass arbitrary properties down to the React Native app. The initialProperties parameter has to be an instance of NSDictionary. The dictionary is internally converted into a JSON object that the top-level JS component can reference.
    
+
    NSArray *imageList = @[@"http://foo.com/bar1.png",
+                       @"http://foo.com/bar2.png"];
+
+NSDictionary *props = @{@"images" : imageList};
+
+RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge
+                                                 moduleName:@"ImageBrowserApp"
+                                          initialProperties:props];
+
    
+
    import React from 'react';
+import {AppRegistry, View, Image} from 'react-native';
+
+class ImageBrowserApp extends React.Component {
+  renderImage(imgURI) {
+    return <Image source={{uri: imgURI}} />;
+  }
+  render() {
+    return <View>{this.props.images.map(this.renderImage)}</View>;
+  }
+}
+
+AppRegistry.registerComponent('ImageBrowserApp', () => ImageBrowserApp);
+
    
+
    RCTRootView also provides a read-write property appProperties. After appProperties is set, the React Native app is re-rendered with new properties. The update is only performed when the new updated properties differ from the previous ones.
    
+
    NSArray *imageList = @[@"http://foo.com/bar3.png",
+                       @"http://foo.com/bar4.png"];
+
+rootView.appProperties = @{@"images" : imageList};
+
    
+
    It is fine to update properties anytime. However, updates have to be performed on the main thread. You use the getter on any thread.
    
+
    
+
    Note: Currently, there is a known issue where setting appProperties during the bridge startup, the change can be lost. See https://github.com/facebook/react-native/issues/20115 for more information.
    
+
    
+
    There is no way to update only a few properties at a time. We suggest that you build it into your own wrapper instead.
    
+
    
+
    Note: Currently, JS functions componentWillReceiveProps and componentWillUpdateProps of the top level RN component will not be called after a prop update. However, you can access the new props in componentWillMount function.
    
+
    
+
    Passing properties from React Native to native
    
+
    The problem exposing properties of native components is covered in detail in this article. In short, export properties with RCT_CUSTOM_VIEW_PROPERTY macro in your custom native component, then just use them in React Native as if the component was an ordinary React Native component.
    
+
    Limits of properties
    
+
    The main drawback of cross-language properties is that they do not support callbacks, which would allow us to handle bottom-up data bindings. Imagine you have a small RN view that you want to be removed from the native parent view as a result of a JS action. There is no way to do that with props, as the information would need to go bottom-up.
    
+
    Although we have a flavor of cross-language callbacks (described here), these callbacks are not always the thing we need. The main problem is that they are not intended to be passed as properties. Rather, this mechanism allows us to trigger a native action from JS, and handle the result of that action in JS.
    
+
    Other ways of cross-language interaction (events and native modules)
    
+
    As stated in the previous chapter, using properties comes with some limitations. Sometimes properties are not enough to drive the logic of our app and we need a solution that gives more flexibility. This chapter covers other communication techniques available in React Native. They can be used for internal communication (between JS and native layers in RN) as well as for external communication (between RN and the 'pure native' part of your app).
    
+
    React Native enables you to perform cross-language function calls. You can execute custom native code from JS and vice versa. Unfortunately, depending on the side we are working on, we achieve the same goal in different ways. For native - we use events mechanism to schedule an execution of a handler function in JS, while for React Native we directly call methods exported by native modules.
    
+
    Calling React Native functions from native (events)
    
+
    Events are described in detail in this article. Note that using events gives us no guarantees about execution time, as the event is handled on a separate thread.
    
+
    Events are powerful, because they allow us to change React Native components without needing a reference to them. However, there are some pitfalls that you can fall into while using them:
    
+
      
+
    • As events can be sent from anywhere, they can introduce spaghetti-style dependencies into your project.
      • 
+
    • Events share namespace, which means that you may encounter some name collisions. Collisions will not be detected statically, which makes them hard to debug.
      • 
+
    • If you use several instances of the same React Native component and you want to distinguish them from the perspective of your event, you'll likely need to introduce identifiers and pass them along with events (you can use the native view's reactTag as an identifier).
      • 
+
    
+
    The common pattern we use when embedding native in React Native is to make the native component's RCTViewManager a delegate for the views, sending events back to JavaScript via the bridge. This keeps related event calls in one place.
    
+
    Calling native functions from React Native (native modules)
    
+
    Native modules are Objective-C classes that are available in JS. Typically one instance of each module is created per JS bridge. They can export arbitrary functions and constants to React Native. They have been covered in detail in this article.
    
+
    The fact that native modules are singletons limits the mechanism in the context of embedding. Let's say we have a React Native component embedded in a native view and we want to update the native, parent view. Using the native module mechanism, we would export a function that not only takes expected arguments, but also an identifier of the parent native view. The identifier would be used to retrieve a reference to the parent view to update. That said, we would need to keep a mapping from identifiers to native views in the module.
    
+
    Although this solution is complex, it is used in RCTUIManager, which is an internal React Native class that manages all React Native views.
    
+
    Native modules can also be used to expose existing native libraries to JS. The Geolocation library is a living example of the idea.
    
+
    
+
    Warning: All native modules share the same namespace. Watch out for name collisions when creating new ones.
    
+
    
+
    Layout computation flow
    
+
    When integrating native and React Native, we also need a way to consolidate two different layout systems. This section covers common layout problems and provides a brief description of mechanisms to address them.
    
+
    Layout of a native component embedded in React Native
    
+
    This case is covered in this article. Basically, as all our native react views are subclasses of UIView, most style and size attributes will work like you would expect out of the box.
    
+
    Layout of a React Native component embedded in native
    
+
    React Native content with fixed size
    
+
    The simplest scenario is when we have a React Native app with a fixed size, which is known to the native side. In particular, a full-screen React Native view falls into this case. If we want a smaller root view, we can explicitly set RCTRootView's frame.
    
+
    For instance, to make an RN app 200 (logical) pixels high, and the hosting view's width wide, we could do:
    
+
    // SomeViewController.m
+
+- (void)viewDidLoad
+{
+  [...]
+  RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge
+                                                   moduleName:appName
+                                            initialProperties:props];
+  rootView.frame = CGRectMake(0, 0, self.view.width, 200);
+  [self.view addSubview:rootView];
+}
+
    
+
    When we have a fixed size root view, we need to respect its bounds on the JS side. In other words, we need to ensure that the React Native content can be contained within the fixed-size root view. The easiest way to ensure this is to use flexbox layout. If you use absolute positioning, and React components are visible outside the root view's bounds, you'll get overlap with native views, causing some features to behave unexpectedly. For instance, 'TouchableHighlight' will not highlight your touches outside the root view's bounds.
    
+
    It's totally fine to update root view's size dynamically by re-setting its frame property. React Native will take care of the content's layout.
    
+
    React Native content with flexible size
    
+
    In some cases we'd like to render content of initially unknown size. Let's say the size will be defined dynamically in JS. We have two solutions to this problem.
    
+
      
+
    1. You can wrap your React Native view in a ScrollView component. This guarantees that your content will always be available and it won't overlap with native views.
      2. 
+
    2. React Native allows you to determine, in JS, the size of the RN app and provide it to the owner of the hosting RCTRootView. The owner is then responsible for re-laying out the subviews and keeping the UI consistent. We achieve this with RCTRootView's flexibility modes.
      3. 
+
    
+
    RCTRootView supports 4 different size flexibility modes:
    
+
    // RCTRootView.h
+
+typedef NS_ENUM(NSInteger, RCTRootViewSizeFlexibility) {
+  RCTRootViewSizeFlexibilityNone = 0,
+  RCTRootViewSizeFlexibilityWidth,
+  RCTRootViewSizeFlexibilityHeight,
+  RCTRootViewSizeFlexibilityWidthAndHeight,
+};
+
    
+
    RCTRootViewSizeFlexibilityNone is the default value, which makes a root view's size fixed (but it still can be updated with setFrame:). The other three modes allow us to track React Native content's size updates. For instance, setting mode to RCTRootViewSizeFlexibilityHeight will cause React Native to measure the content's height and pass that information back to RCTRootView's delegate. An arbitrary action can be performed within the delegate, including setting the root view's frame, so the content fits. The delegate is called only when the size of the content has changed.
    
+
    
+
    Warning: Making a dimension flexible in both JS and native leads to undefined behavior. For example - don't make a top-level React component's width flexible (with flexbox) while you're using RCTRootViewSizeFlexibilityWidth on the hosting RCTRootView.
    
+
    
+
    Let's look at an example.
    
+
    // FlexibleSizeExampleView.m
+
+- (instancetype)initWithFrame:(CGRect)frame
+{
+  [...]
+
+  _rootView = [[RCTRootView alloc] initWithBridge:bridge
+  moduleName:@"FlexibilityExampleApp"
+  initialProperties:@{}];
+
+  _rootView.delegate = self;
+  _rootView.sizeFlexibility = RCTRootViewSizeFlexibilityHeight;
+  _rootView.frame = CGRectMake(0, 0, self.frame.size.width, 0);
+}
+
+#pragma mark - RCTRootViewDelegate
+- (void)rootViewDidChangeIntrinsicSize:(RCTRootView *)rootView
+{
+  CGRect newFrame = rootView.frame;
+  newFrame.size = rootView.intrinsicContentSize;
+
+  rootView.frame = newFrame;
+}
+
    
+
    In the example we have a FlexibleSizeExampleView view that holds a root view. We create the root view, initialize it and set the delegate. The delegate will handle size updates. Then, we set the root view's size flexibility to RCTRootViewSizeFlexibilityHeight, which means that rootViewDidChangeIntrinsicSize: method will be called every time the React Native content changes its height. Finally, we set the root view's width and position. Note that we set there height as well, but it has no effect as we made the height RN-dependent.
    
+
    You can checkout full source code of the example here.
    
+
    It's fine to change root view's size flexibility mode dynamically. Changing flexibility mode of a root view will schedule a layout recalculation and the delegate rootViewDidChangeIntrinsicSize: method will be called once the content size is known.
    
+
    
+
    Note: React Native layout calculation is performed on a special thread, while native UI view updates are done on the main thread. This may cause temporary UI inconsistencies between native and React Native. This is a known problem and our team is working on synchronizing UI updates coming from different sources.
    
+
    
+
    
+
    Note: React Native does not perform any layout calculations until the root view becomes a subview of some other views. If you want to hide React Native view until its dimensions are known, add the root view as a subview and make it initially hidden (use UIView's hidden property). Then change its visibility in the delegate method.

    Communication between native and React Native
    In Integrating with Existing Apps guide and Native UI Components guide we learn how to embed React Native in a native component and vice versa. When we mix native and React Native components, we'll eventually find a need to communicate between these two worlds. Some ways to achieve that have been already mentioned in other guides.

+
+RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge
+                                                 moduleName:@"ImageBrowserApp"
+                                          initialProperties:props];

    import React from 'react';

+
+class ImageBrowserApp extends React.Component {
+  renderImage(imgURI) {
+    return <Image source={{uri: imgURI}} />;
+  }
+  render() {
+    return <View>{this.props.images.map(this.renderImage)}</View>;
+  }
+}
+
+AppRegistry.registerComponent('ImageBrowserApp', () => ImageBrowserApp);
+
    
+
    RCTRootView also provides a read-write property appProperties. After appProperties is set, the React Native app is re-rendered with new properties. The update is only performed when the new updated properties differ from the previous ones.

+                                                   moduleName:appName
+                                            initialProperties:props];

+
    
+
    When we have a fixed size root view, we need to respect its bounds on the JS side. In other words, we need to ensure that the React Native content can be contained within the fixed-size root view. The easiest way to ensure this is to use flexbox layout. If you use absolute positioning, and React components are visible outside the root view's bounds, you'll get overlap with native views, causing some features to behave unexpectedly. For instance, 'TouchableHighlight' will not highlight your touches outside the root view's bounds.
    
+
    It's totally fine to update root view's size dynamically by re-setting its frame property. React Native will take care of the content's layout.
    
+
    React Native content with flexible size
    
+
    In some cases we'd like to render content of initially unknown size. Let's say the size will be defined dynamically in JS. We have two solutions to this problem.
    
+
      
+
    1. You can wrap your React Native view in a ScrollView component. This guarantees that your content will always be available and it won't overlap with native views.
      2. 
+
    2. React Native allows you to determine, in JS, the size of the RN app and provide it to the owner of the hosting RCTRootView. The owner is then responsible for re-laying out the subviews and keeping the UI consistent. We achieve this with RCTRootView's flexibility modes.
      3. 
+
    
+
    RCTRootView supports 4 different size flexibility modes:
    
+
    // RCTRootView.h
+
+typedef NS_ENUM(NSInteger, RCTRootViewSizeFlexibility) {
+  RCTRootViewSizeFlexibilityNone = 0,
+  RCTRootViewSizeFlexibilityWidth,
+  RCTRootViewSizeFlexibilityHeight,
+  RCTRootViewSizeFlexibilityWidthAndHeight,
+};
+
    
+
    RCTRootViewSizeFlexibilityNone is the default value, which makes a root view's size fixed (but it still can be updated with setFrame:). The other three modes allow us to track React Native content's size updates. For instance, setting mode to RCTRootViewSizeFlexibilityHeight will cause React Native to measure the content's height and pass that information back to RCTRootView's delegate. An arbitrary action can be performed within the delegate, including setting the root view's frame, so the content fits. The delegate is called only when the size of the content has changed.
    
+
    
+
    Warning: Making a dimension flexible in both JS and native leads to undefined behavior. For example - don't make a top-level React component's width flexible (with flexbox) while you're using RCTRootViewSizeFlexibilityWidth on the hosting RCTRootView.
    
+
    
+
    Let's look at an example.
    
+
    // FlexibleSizeExampleView.m
+
+- (instancetype)initWithFrame:(CGRect)frame
+{
+  [...]
+
+  _rootView = [[RCTRootView alloc] initWithBridge:bridge
+  moduleName:@"FlexibilityExampleApp"
+  initialProperties:@{}];
+
+  _rootView.delegate = self;
+  _rootView.sizeFlexibility = RCTRootViewSizeFlexibilityHeight;
+  _rootView.frame = CGRectMake(0, 0, self.frame.size.width, 0);
+}
+
+#pragma mark - RCTRootViewDelegate
+- (void)rootViewDidChangeIntrinsicSize:(RCTRootView *)rootView
+{
+  CGRect newFrame = rootView.frame;
+  newFrame.size = rootView.intrinsicContentSize;
+
+  rootView.frame = newFrame;
+}
+
    
+
    In the example we have a FlexibleSizeExampleView view that holds a root view. We create the root view, initialize it and set the delegate. The delegate will handle size updates. Then, we set the root view's size flexibility to RCTRootViewSizeFlexibilityHeight, which means that rootViewDidChangeIntrinsicSize: method will be called every time the React Native content changes its height. Finally, we set the root view's width and position. Note that we set there height as well, but it has no effect as we made the height RN-dependent.
    
+
    You can checkout full source code of the example here.
    
+
    It's fine to change root view's size flexibility mode dynamically. Changing flexibility mode of a root view will schedule a layout recalculation and the delegate rootViewDidChangeIntrinsicSize: method will be called once the content size is known.
    
+
    
+
    Note: React Native layout calculation is performed on a special thread, while native UI view updates are done on the main thread. This may cause temporary UI inconsistencies between native and React Native. This is a known problem and our team is working on synchronizing UI updates coming from different sources.
    
+
    
+
    
+
    Note: React Native does not perform any layout calculations until the root view becomes a subview of some other views. If you want to hide React Native view until its dimensions are known, add the root view as a subview and make it initially hidden (use UIView's hidden property). Then change its visibility in the delegate method.

    How to Contribute
    We want to make contributing to this project as easy and transparent as possible. Read on to learn more about our development process and how to propose bug fixes and improvements.
    
+
    Code of Conduct
    
+
    Facebook has adopted a Code of Conduct that we expect project participants to adhere to. Please read the full text so that you can understand what actions will and will not be tolerated.
    
+
    Our Development Process
    
+
    Most changes from engineers at Facebook will sync to GitHub through a bridge with Facebook's internal source control. Changes from the community are handled through GitHub pull requests. Once a change made on GitHub is approved, it will first be imported into Facebook's internal source control. The change will eventually sync back to GitHub as a single commit once it has passed Facebook's internal tests.
    
+
    Branch Organization
    
+
    We will do our best to keep the master branch in good shape, with tests passing at all times. Sometimes, commits from Facebook engineers may land on master, temporarily breaking tests. While we have a comprehensive suite of tests that every diff must go through before it syncs out to GitHub, there are still some differences in development environments that prevent us from catching every one of these failures. We will do our best to resolve these quickly.
    
+
    Each React Native version is built from a release branch named after the version (e.g. 0.NN-stable). Each release branch is cut from the master branch and subjected to a 30 day soak period, during which contributors will closely monitor for any regressions. You can opt into these release candidates by installing react-native@next from npm. The release will eventually be promoted to stable, and published to npm as react-native@latest.
    
+
    To see what changes are coming and provide better feedback to React Native contributors, use the latest release candidate whenever possible. By the time a release candidate is released, the changes it contains will have been shipped in production Facebook apps for over two weeks.
    
+
    Bugs
    
+
    Where to Find Known Issues
    
+
    We are using GitHub Issues for our public bugs.
    
+
    Reporting a New Issue
    
+
    The best way to get your bug fixed is to provide a reduced test case. You can use a tool such as Snack to provide a minimal example.
    
+
    Security Bugs
    
+
    Facebook has a bounty program for the safe disclosure of security bugs. In those cases, please go through the process outlined on that page and do not file a public issue.
    
+
    How to Get in Touch
    
+
    We have a discussion forum for React and React Native: discuss.reactjs.org
    
+
    There is also an active community of users on the Discord chat platform in case you need help with React or React Native.
    
+
    Request for Comments (RFC)
    
+
    Many changes, including bug fixes and documentation improvements can be implemented and reviewed via the normal GitHub pull request workflow.
    
+
    Some changes though are “substantial”, and we ask that these be put through a bit of a design process and produce a consensus among the React Native core team.
    
+
    The "RFC" (request for comments) process is intended to provide a consistent and controlled path for new features to be proposed and championed to then enter the project.
    
+
    It is inspired by the React RFCs repository, but today we don't expect for every substantial change to go through this process; however, we hope that this brings more awareness to the community.
    
+
    You can contribute by visiting the discussions and proposals repository.
    
+
    Get Involved
    
+
    There are many ways to contribute to React Native, and many of them do not involve writing any code. Here's a few ideas to get started:
    
+
      
+
    • Simply start using React Native. Go through the Getting Started guide. Does everything work as expected? If not, we're always looking for improvements.
      • 
+
    • Look through the open issues. Provide workarounds, ask for clarification, or suggest labels. Active community members can get access to our issue management tools, unlocking the ability to label, close, or re-open issues.
      • 
+
    • If you find an issue you would like to fix, open a pull request. Issues tagged as Good first issue are a good place to get started.
      • 
+
    • Read through the docs. If you find anything that is confusing or can be improved, you can make edits by clicking "Edit" at the top of most docs.
      • 
+
    • Browse Stack Overflow and answer questions. This will help you get familiarized with common pitfalls or misunderstandings, which can be useful when contributing updates to the documentation.
      • 
+
    • Before opening your pull request, make sure you have fully tested your changes. Test your changes locally and by running the various tests provided.
      • 
+
    • Check out the Testing your changes guide to find out about the numerous tests which has been provided to help ensure that any new changes wont cause a regression.
      • 
+
    
+
    Core contributors to React Native meet regularly and post their meeting notes online. You can also find ad hoc discussions at https://discuss.reactjs.org/.
    
+
    Pull requests
    
+
    Your first pull request
    
+
    So you have decided to contribute code back to upstream by opening a pull request. You've invested a good chunk of time, and we appreciate it. We will do our best to work with you and get the PR looked at.
    
+
    If you are working on your first pull request, you can learn how from this free video series: How to Contribute to an Open Source Project on GitHub
    
+
    Proposing a change
    
+
    If you intend to change the API, or make any non-trivial changes to the implementation, we recommend filing an issue. This lets us reach an agreement on your proposal before you put significant effort into it.
    
+
    If you're only fixing a bug, it's fine to submit a pull request right away but we still recommend to file an issue detailing what you're fixing. This is helpful in case we don't accept that specific fix but want to keep track of the issue.
    
+
    Sending a pull request
    
+
    Small pull requests are much easier to review and more likely to get merged. Make sure the PR does only one thing, otherwise please split it.
    
+
    Please make sure the following is done when submitting a pull request:
    
+
      
+
    1. Fork the repository and create your branch from master.
      2. 
+
    2. Add the copyright notice to the top of any new files you've added.
      3. 
+
    3. Describe your test plan in your pull request description (e.g. how did you test this?)
      4. 
+
    4. Make sure your code lints (npm run lint and npm run prettier).
      5. 
+
    5. If you haven't already, complete the Contributor License Agreement ("CLA").
      6. 
+
    
+
    Contributor License Agreement ("CLA")
    
+
    In order to accept your pull request, we need you to submit a CLA. You only need to do this once to work on any of Facebook's open source projects.
    
+
    Complete your CLA here.
    
+
    Changelog
    
+
    Provide a changelog entry to help reviewers during the release process. Changes that do not impact React Native developers may be ommitted from the changelog.
    
+
    A changelog entry has the following format:
    
+
    [CATEGORY] [TYPE] - Message
+
    
+
      
+
    • CATEGORY may be:

    Changelog Examples
    
+
      
+
    • [General][added] - Add snapToOffsets prop to ScrollView component
      • 
+
    • [General][fixed] - Fix various issues in snapToInterval on ScrollView component
      • 
+
    • [iOS][fixed] - Fix crash in RCTImagePicker
      • 
+
    
+
    Test plan
    
+
    A good test plan has the exact commands you ran and their output, provides screenshots or videos if the pull request changes UI or updates the website.
    
+
      
+
    • If you've added code that should be tested, add tests!
      • 
+
    • If you've changed APIs, update the documentation via an additional PR to the react-native-website repo.
      • 
+
    • If you've updated the docs, verify the website locally and submit screenshots if applicable (see the react-native-website README).
      • 
+
    
+
    See What is a Test Plan? to learn more.
    
+
    Coding Style
    
+
    We use Prettier to format our JavaScript code. This saves you time and energy as you can let Prettier fix up any formatting issues automatically through its editor integrations, or by manually running npm run prettier. We also use a linter to catch styling issues that may exist in your code. You can check the status of your code styling by simply running npm run lint.
    
+
    However, there are still some styles that the linter cannot pick up, notably in Java or Objective-C code.
    
+
    Objective-C:
    
+
      
+
    • Space after @property declarations
      • 
+
    • Brackets on every if, on the same line
      • 
+
    • - method, @interface, and @implementation brackets on the following line
      • 
+
    • Try to keep it around 80 characters line length (sometimes it's just not possible...)
      • 
+
    • * operator goes with the variable name (e.g. NSObject *variableName;)
      • 
+
    
+
    Java:
    
+
      
+
    • If a method call spans multiple lines closing bracket is on the same line as the last argument.
      • 
+
    • If a method header doesn't fit on one line each argument goes on a separate line.
      • 
+
    • 100 character line length
      • 
+
    
+
    License
    
+
    By contributing to React Native, you agree that your contributions will be licensed under the LICENSE file.

    While the built-in web view has a lot of features, it is not possible to handle every use-case in React Native. You can, however, extend the web view with native code without forking React Native or duplicating all the existing web view code.
    
+
    Before you do this, you should be familiar with the concepts in native UI components. You should also familiarise yourself with the native code for web views, as you will have to use this as a reference when implementing new features—although a deep understanding is not required.
    
+
    Native Code
    
+
    To get started, you'll need to create a subclass of ReactWebViewManager, ReactWebView, and ReactWebViewClient. In your view manager, you'll then need to override:
    
+
      
+
    • createReactWebViewInstance
      • 
+
    • getName
      • 
+
    • addEventEmitters
      • 
+
    
+
    @ReactModule(name = CustomWebViewManager.REACT_CLASS)
+public class CustomWebViewManager extends ReactWebViewManager {
+  /* This name must match what we're referring to in JS */
+  protected static final String REACT_CLASS = "RCTCustomWebView";
+
+  protected static class CustomWebViewClient extends ReactWebViewClient { }
+
+  protected static class CustomWebView extends ReactWebView {
+    public CustomWebView(ThemedReactContext reactContext) {
+      super(reactContext);
+    }
+  }
+
+  @Override
+  protected ReactWebView createReactWebViewInstance(ThemedReactContext reactContext) {
+    return new CustomWebView(reactContext);
+  }
+
+  @Override
+  public String getName() {
+    return REACT_CLASS;
+  }
+
+  @Override
+  protected void addEventEmitters(ThemedReactContext reactContext, WebView view) {
+    view.setWebViewClient(new CustomWebViewClient());
+  }
+}
+
    
+
    You'll need to follow the usual steps to register the module.
    
+
    Adding New Properties
    
+
    To add a new property, you'll need to add it to CustomWebView, and then expose it in CustomWebViewManager.
    
+
    public class CustomWebViewManager extends ReactWebViewManager {
+  ...
+
+  protected static class CustomWebView extends ReactWebView {
+    public CustomWebView(ThemedReactContext reactContext) {
+      super(reactContext);
+    }
+
+    protected @Nullable String mFinalUrl;
+
+    public void setFinalUrl(String url) {
+        mFinalUrl = url;
+    }
+
+    public String getFinalUrl() {
+        return mFinalUrl;
+    }
+  }
+
+  ...
+
+  @ReactProp(name = "finalUrl")
+  public void setFinalUrl(WebView view, String url) {
+    ((CustomWebView) view).setFinalUrl(url);
+  }
+}
+
    
+
    Adding New Events
    
+
    For events, you'll first need to make create event subclass.
    
+
    // NavigationCompletedEvent.java
+public class NavigationCompletedEvent extends Event<NavigationCompletedEvent> {
+  private WritableMap mParams;
+
+  public NavigationCompletedEvent(int viewTag, WritableMap params) {
+    super(viewTag);
+    this.mParams = params;
+  }
+
+  @Override
+  public String getEventName() {
+    return "navigationCompleted";
+  }
+
+  @Override
+  public void dispatch(RCTEventEmitter rctEventEmitter) {
+    init(getViewTag());
+    rctEventEmitter.receiveEvent(getViewTag(), getEventName(), mParams);
+  }
+}
+
    
+
    You can trigger the event in your web view client. You can hook existing handlers if your events are based on them.
    
+
    You should refer to ReactWebViewManager.java in the React Native codebase to see what handlers are available and how they are implemented. You can extend any methods here to provide extra functionality.
    
+
    public class NavigationCompletedEvent extends Event<NavigationCompletedEvent> {
+  private WritableMap mParams;
+
+  public NavigationCompletedEvent(int viewTag, WritableMap params) {
+    super(viewTag);
+    this.mParams = params;
+  }
+
+  @Override
+  public String getEventName() {
+    return "navigationCompleted";
+  }
+
+  @Override
+  public void dispatch(RCTEventEmitter rctEventEmitter) {
+    init(getViewTag());
+    rctEventEmitter.receiveEvent(getViewTag(), getEventName(), mParams);
+  }
+}
+
+// CustomWebViewManager.java
+protected static class CustomWebViewClient extends ReactWebViewClient {
+  @Override
+  public boolean shouldOverrideUrlLoading(WebView view, String url) {
+    boolean shouldOverride = super.shouldOverrideUrlLoading(view, url);
+    String finalUrl = ((CustomWebView) view).getFinalUrl();
+
+    if (!shouldOverride && url != null && finalUrl != null && new String(url).equals(finalUrl)) {
+      final WritableMap params = Arguments.createMap();
+      dispatchEvent(view, new NavigationCompletedEvent(view.getId(), params));
+    }
+
+    return shouldOverride;
+  }
+}
+
    
+
    Finally, you'll need to expose the events in CustomWebViewManager through getExportedCustomDirectEventTypeConstants. Note that currently, the default implementation returns null, but this may change in the future.
    
+
    public class CustomWebViewManager extends ReactWebViewManager {
+  ...
+
+  @Override
+  public @Nullable
+  Map getExportedCustomDirectEventTypeConstants() {
+    Map<String, Object> export = super.getExportedCustomDirectEventTypeConstants();
+    if (export == null) {
+      export = MapBuilder.newHashMap();
+    }
+    export.put("navigationCompleted", MapBuilder.of("registrationName", "onNavigationCompleted"));
+    return export;
+  }
+}
+
    
+
    JavaScript Interface
    
+
    To use your custom web view, you'll need to create a class for it. Your class must:
    
+
      
+
    • Export all the prop types from WebView.propTypes
      • 
+
    • Return a WebView component with the prop nativeConfig.component set to your native component (see below)
      • 
+
    
+
    To get your native component, you must use requireNativeComponent: the same as for regular custom components. However, you must pass in an extra third argument, WebView.extraNativeComponentConfig. This third argument contains prop types that are only required for native code.
    
+
    import React, {Component, PropTypes} from 'react';
+import {WebView, requireNativeComponent} from 'react-native';
+
+export default class CustomWebView extends Component {
+  static propTypes = WebView.propTypes;
+
+  render() {
+    return (
+      <WebView {...this.props} nativeConfig={{component: RCTCustomWebView}} />
+    );
+  }
+}
+
+const RCTCustomWebView = requireNativeComponent(
+  'RCTCustomWebView',
+  CustomWebView,
+  WebView.extraNativeComponentConfig,
+);
+
    
+
    If you want to add custom props to your native component, you can use nativeConfig.props on the web view.
    
+
    For events, the event handler must always be set to a function. This means it isn't safe to use the event handler directly from this.props, as the user might not have provided one. The standard approach is to create a event handler in your class, and then invoking the event handler given in this.props if it exists.
    
+
    If you are unsure how something should be implemented from the JS side, look at WebView.android.js in the React Native source.
    
+
    export default class CustomWebView extends Component {
+  static propTypes = {
+    ...WebView.propTypes,
+    finalUrl: PropTypes.string,
+    onNavigationCompleted: PropTypes.func,
+  };
+
+  static defaultProps = {
+    finalUrl: 'about:blank',
+  };
+
+  _onNavigationCompleted = (event) => {
+    const {onNavigationCompleted} = this.props;
+    onNavigationCompleted && onNavigationCompleted(event);
+  };
+
+  render() {
+    return (
+      <WebView
+        {...this.props}
+        nativeConfig={{
+          component: RCTCustomWebView,
+          props: {
+            finalUrl: this.props.finalUrl,
+            onNavigationCompleted: this._onNavigationCompleted,
+          },
+        }}
+      />
+    );
+  }
+}
+
    
+
    Just like for regular native components, you must provide all your prop types in the component to have them forwarded on to the native component. However, if you have some prop types that are only used internally in component, you can add them to the nativeOnly property of the third argument previously mentioned. For event handlers, you have to use the value true instead of a regular prop type.
    
+
    For example, if you wanted to add an internal event handler called onScrollToBottom, you would use,
    
+
    const RCTCustomWebView = requireNativeComponent(
+  'RCTCustomWebView',
+  CustomWebView,
+  {
+    ...WebView.extraNativeComponentConfig,
+    nativeOnly: {
+      ...WebView.extraNativeComponentConfig.nativeOnly,
+      onScrollToBottom: true,
+    },
+  },
+);
+
    
+

    Custom WebView
    While the built-in web view has a lot of features, it is not possible to handle every use-case in React Native. You can, however, extend the web view with native code without forking React Native or duplicating all the existing web view code.
    
+
    Before you do this, you should be familiar with the concepts in native UI components. You should also familiarise yourself with the native code for web views, as you will have to use this as a reference when implementing new features—although a deep understanding is not required.
    
+
    Native Code
    
+
    Like for regular native components, you need a view manager and an web view.
    
+
    For the view, you'll need to make a subclass of RCTWebView.
    
+
    // RCTCustomWebView.h
+#import <React/RCTWebView.h>
+
+@interface RCTCustomWebView : RCTWebView
+
+@end
+
+// RCTCustomWebView.m
+#import "RCTCustomWebView.h"
+
+@interface RCTCustomWebView ()
+
+@end
+
+@implementation RCTCustomWebView { }
+
+@end
+
    
+
    For the view manager, you need to make a subclass RCTWebViewManager. You must still include:
    
+
      
+
    • (UIView *)view that returns your custom view
      • 
+
    • The RCT_EXPORT_MODULE() tag
      • 
+
    
+
    // RCTCustomWebViewManager.h
+#import <React/RCTWebViewManager.h>
+
+@interface RCTCustomWebViewManager : RCTWebViewManager
+
+@end
+
+// RCTCustomWebViewManager.m
+#import "RCTCustomWebViewManager.h"
+#import "RCTCustomWebView.h"
+
+@interface RCTCustomWebViewManager () <RCTWebViewDelegate>
+
+@end
+
+@implementation RCTCustomWebViewManager { }
+
+RCT_EXPORT_MODULE()
+
+- (UIView *)view
+{
+  RCTCustomWebView *webView = [RCTCustomWebView new];
+  webView.delegate = self;
+  return webView;
+}
+
+@end
+
    
+
    Adding New Events and Properties
    
+
    Adding new properties and events is the same as regular UI components. For properties, you define an @property in the header. For events, you define a RCTDirectEventBlock in the view's @interface.
    
+
    // RCTCustomWebView.h
+@property (nonatomic, copy) NSString *finalUrl;
+
+// RCTCustomWebView.m
+@interface RCTCustomWebView ()
+
+@property (nonatomic, copy) RCTDirectEventBlock onNavigationCompleted;
+
+@end
+
    
+
    Then expose it in the view manager's @implementation.
    
+
    // RCTCustomWebViewManager.m
+RCT_EXPORT_VIEW_PROPERTY(onNavigationCompleted, RCTDirectEventBlock)
+RCT_EXPORT_VIEW_PROPERTY(finalUrl, NSString)
+
    
+
    Extending Existing Events
    
+
    You should refer to RCTWebView.m in the React Native codebase to see what handlers are available and how they are implemented. You can extend any methods here to provide extra functionality.
    
+
    By default, most methods aren't exposed from RCTWebView. If you need to expose them, you need to create an Objective C category, and then expose all the methods you need to use.
    
+
    // RCTWebView+Custom.h
+#import <React/RCTWebView.h>
+
+@interface RCTWebView (Custom)
+- (BOOL)webView:(__unused UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;
+- (NSMutableDictionary<NSString *, id> *)baseEvent;
+@end
+
    
+
    Once these are exposed, you can reference them in your custom web view class.
    
+
    // RCTCustomWebView.m
+
+// Remember to import the category file.
+#import "RCTWebView+Custom.h"
+
+- (BOOL)webView:(__unused UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
+ navigationType:(UIWebViewNavigationType)navigationType
+{
+  BOOL allowed = [super webView:webView shouldStartLoadWithRequest:request navigationType:navigationType];
+
+  if (allowed) {
+    NSString* url = request.URL.absoluteString;
+    if (url && [url isEqualToString:_finalUrl]) {
+      if (_onNavigationCompleted) {
+        NSMutableDictionary<NSString *, id> *event = [self baseEvent];
+        _onNavigationCompleted(event);
+      }
+    }
+  }
+
+  return allowed;
+}
+
    
+
    JavaScript Interface
    
+
    To use your custom web view, you'll need to create a class for it. Your class must:
    
+
      
+
    • Export all the prop types from WebView.propTypes

+}
+
+const RCTCustomWebView = requireNativeComponent(
+  'RCTCustomWebView',
+  CustomWebView,
+  WebView.extraNativeComponentConfig,
+);
+
    
+
    If you want to add custom props to your native component, you can use nativeConfig.props on the web view. For iOS, you should also set the nativeConfig.viewManager prop with your custom WebView ViewManager as in the example above.
    
+
    For events, the event handler must always be set to a function. This means it isn't safe to use the event handler directly from this.props, as the user might not have provided one. The standard approach is to create a event handler in your class, and then invoking the event handler given in this.props if it exists.
    
+
    If you are unsure how something should be implemented from the JS side, look at WebView.ios.js in the React Native source.
    
+
    export default class CustomWebView extends Component {
+  static propTypes = {
+    ...WebView.propTypes,
+    finalUrl: PropTypes.string,
+    onNavigationCompleted: PropTypes.func,
+  };
+
+  static defaultProps = {
+    finalUrl: 'about:blank',
+  };
+
+  _onNavigationCompleted = (event) => {
+    const {onNavigationCompleted} = this.props;
+    onNavigationCompleted && onNavigationCompleted(event);
+  };
+
+  render() {
+    return (
+      <WebView
+        {...this.props}
+        nativeConfig={{
+          component: RCTCustomWebView,
+          props: {
+            finalUrl: this.props.finalUrl,
+            onNavigationCompleted: this._onNavigationCompleted,
+          },
+          viewManager: CustomWebViewManager,
+        }}
+      />
+    );
+  }
+}
+
    
+
    Just like for regular native components, you must provide all your prop types in the component to have them forwarded on to the native component. However, if you have some prop types that are only used internally in component, you can add them to the nativeOnly property of the third argument previously mentioned. For event handlers, you have to use the value true instead of a regular prop type.
    
+
    For example, if you wanted to add an internal event handler called onScrollToBottom, you would use,
    
+
    const RCTCustomWebView = requireNativeComponent(
+  'RCTCustomWebView',
+  CustomWebView,
+  {
+    ...WebView.extraNativeComponentConfig,
+    nativeOnly: {
+      ...WebView.extraNativeComponentConfig.nativeOnly,
+      onScrollToBottom: true,
+    },
+  },
+);

+Custom WebView · React Native
    0.58
    Edit
    Custom WebView
    While the built-in web view has a lot of features, it is not possible to handle every use-case in React Native. You can, however, extend the web view with native code without forking React Native or duplicating all the existing web view code.
    
+
    Before you do this, you should be familiar with the concepts in native UI components. You should also familiarise yourself with the native code for web views, as you will have to use this as a reference when implementing new features—although a deep understanding is not required.
    
+
    Native Code
    
+
    Like for regular native components, you need a view manager and an web view.
    
+
    For the view, you'll need to make a subclass of RCTWebView.
    
+
    // RCTCustomWebView.h
+#import <React/RCTWebView.h>
+
+@interface RCTCustomWebView : RCTWebView
+
+@end
+
+// RCTCustomWebView.m
+#import "RCTCustomWebView.h"
+
+@interface RCTCustomWebView ()
+
+@end
+
+@implementation RCTCustomWebView { }
+
+@end
+
    
+
    For the view manager, you need to make a subclass RCTWebViewManager. You must still include:
    
+
      
+
    • (UIView *)view that returns your custom view
      • 
+
    • The RCT_EXPORT_MODULE() tag
      • 
+
    
+
    // RCTCustomWebViewManager.h
+#import <React/RCTWebViewManager.h>
+
+@interface RCTCustomWebViewManager : RCTWebViewManager
+
+@end
+
+// RCTCustomWebViewManager.m
+#import "RCTCustomWebViewManager.h"
+#import "RCTCustomWebView.h"
+
+@interface RCTCustomWebViewManager () <RCTWebViewDelegate>
+
+@end
+
+@implementation RCTCustomWebViewManager { }
+
+RCT_EXPORT_MODULE()
+
+- (UIView *)view
+{
+  RCTCustomWebView *webView = [RCTCustomWebView new];
+  webView.delegate = self;
+  return webView;
+}
+
+@end
+
    
+
    Adding New Events and Properties
    
+
    Adding new properties and events is the same as regular UI components. For properties, you define an @property in the header. For events, you define a RCTDirectEventBlock in the view's @interface.
    
+
    // RCTCustomWebView.h
+@property (nonatomic, copy) NSString *finalUrl;
+
+// RCTCustomWebView.m
+@interface RCTCustomWebView ()
+
+@property (nonatomic, copy) RCTDirectEventBlock onNavigationCompleted;
+
+@end
+
    
+
    Then expose it in the view manager's @implementation.
    
+
    // RCTCustomWebViewManager.m
+RCT_EXPORT_VIEW_PROPERTY(onNavigationCompleted, RCTDirectEventBlock)
+RCT_EXPORT_VIEW_PROPERTY(finalUrl, NSString)
+
    
+
    Extending Existing Events
    
+
    You should refer to RCTWebView.m in the React Native codebase to see what handlers are available and how they are implemented. You can extend any methods here to provide extra functionality.
    
+
    By default, most methods aren't exposed from RCTWebView. If you need to expose them, you need to create an Objective C category, and then expose all the methods you need to use.
    
+
    // RCTWebView+Custom.h
+#import <React/RCTWebView.h>
+
+@interface RCTWebView (Custom)
+- (BOOL)webView:(__unused UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;
+- (NSMutableDictionary<NSString *, id> *)baseEvent;
+@end
+
    
+
    Once these are exposed, you can reference them in your custom web view class.
    
+
    // RCTCustomWebView.m
+
+// Remember to import the category file.
+#import "RCTWebView+Custom.h"
+
+- (BOOL)webView:(__unused UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
+ navigationType:(UIWebViewNavigationType)navigationType
+{
+  BOOL allowed = [super webView:webView shouldStartLoadWithRequest:request navigationType:navigationType];
+
+  if (allowed) {
+    NSString* url = request.URL.absoluteString;
+    if (url && [url isEqualToString:_finalUrl]) {
+      if (_onNavigationCompleted) {
+        NSMutableDictionary<NSString *, id> *event = [self baseEvent];
+        _onNavigationCompleted(event);
+      }
+    }
+  }
+
+  return allowed;
+}
+
    
+
    JavaScript Interface
    
+
    To use your custom web view, you'll need to create a class for it. Your class must:
    
+
      
+
    • Export all the prop types from WebView.propTypes
      • 
+
    • Return a WebView component with the prop nativeConfig.component set to your native component (see below)
      • 
+
    
+
    To get your native component, you must use requireNativeComponent: the same as for regular custom components. However, you must pass in an extra third argument, WebView.extraNativeComponentConfig. This third argument contains prop types that are only required for native code.
    
+
    import React, {Component, PropTypes} from 'react';
+import {WebView, requireNativeComponent, NativeModules} from 'react-native';
+const {CustomWebViewManager} = NativeModules;
+
+export default class CustomWebView extends Component {
+  static propTypes = WebView.propTypes;
+
+  render() {
+    return (
+      <WebView
+        {...this.props}
+        nativeConfig={{
+          component: RCTCustomWebView,
+          viewManager: CustomWebViewManager,
+        }}
+      />
+    );
+  }
+}
+
+const RCTCustomWebView = requireNativeComponent(
+  'RCTCustomWebView',
+  CustomWebView,
+  WebView.extraNativeComponentConfig,
+);
+
    
+
    If you want to add custom props to your native component, you can use nativeConfig.props on the web view. For iOS, you should also set the nativeConfig.viewManager prop with your custom WebView ViewManager as in the example above.
    
+
    For events, the event handler must always be set to a function. This means it isn't safe to use the event handler directly from this.props, as the user might not have provided one. The standard approach is to create a event handler in your class, and then invoking the event handler given in this.props if it exists.
    
+

+
    export default class CustomWebView extends Component {
+  static propTypes = {
+    ...WebView.propTypes,
+    finalUrl: PropTypes.string,
+    onNavigationCompleted: PropTypes.func,
+  };
+
+  static defaultProps = {
+    finalUrl: 'about:blank',
+  };
+
+  _onNavigationCompleted = (event) => {
+    const {onNavigationCompleted} = this.props;
+    onNavigationCompleted && onNavigationCompleted(event);
+  };
+
+  render() {
+    return (
+      <WebView
+        {...this.props}
+        nativeConfig={{
+          component: RCTCustomWebView,
+          props: {
+            finalUrl: this.props.finalUrl,
+            onNavigationCompleted: this._onNavigationCompleted,
+          },
+          viewManager: CustomWebViewManager,
+        }}
+      />
+    );
+  }
+}
+
    
+

+    },
+  },
+);

    Opens the standard Android date picker dialog.
    
+
    The available keys for the options object are:
    
+
      
+
    • date (Date object or timestamp in milliseconds) - date to show by default
      • 
+
    • minDate (Date or timestamp in milliseconds) - minimum date that can be selected

+
    • maxDate (Date object or timestamp in milliseconds) - maximum date that can be selected
      • 
+
    • mode (enum('calendar', 'spinner', 'default')) - To set the date-picker mode to calendar/spinner/default
+
        
+
      • 'calendar': Show a date picker in calendar mode.
        • 
+
      • 'spinner': Show a date picker in spinner mode.
        •

      • 
+

    Returns a Promise which will be invoked an object containing action, year, month (0-11), day if the user picked a date. If the user dismissed the dialog, the Promise will still be resolved with action being DatePickerAndroid.dismissedAction and all the other keys being undefined. Always check whether the action is equal to DatePickerAndroid.dateSetAction before reading the values.

    Note the native date picker dialog has some UI glitches on Android 4 and lower when using the minDate and maxDate options.

    DatePickerIOS
    Use DatePickerIOS to render a date/time picker (selector) on iOS. This is a controlled component, so you must hook in to the onDateChange callback and update the date prop in order for the component to update, otherwise the user's change will be reverted immediately to reflect props.date as the source of truth.
    
+
    Example
    
+
    import React, {Component} from 'react';
+import {DatePickerIOS, View, StyleSheet} from 'react-native';
+
+export default class App extends Component {
+  constructor(props) {
+    super(props);
+    this.state = {chosenDate: new Date()};
+
+    this.setDate = this.setDate.bind(this);
+  }
+
+  setDate(newDate) {
+    this.setState({chosenDate: newDate});
+  }
+
+  render() {
+    return (
+      <View style={styles.container}>
+        <DatePickerIOS
+          date={this.state.chosenDate}
+          onDateChange={this.setDate}
+        />
+      </View>
+    );
+  }
+}

+
    
+
    
+
    minimumDate
    
+
    Minimum date.
    
+
    Restricts the range of possible date/time values.
    
+
+
+
+
+
+
+

    The date picker mode.
    
+
+
+
+
+
+
+
+
    TypeRequired
    enum('date', 'time', 'datetime')No
    
+
    Example with mode set to date, time, and datetime: 
    
+
    
+
    locale
    
+
    The locale for the date picker. Value needs to be a Locale ID.

+
    
+
    timeZoneOffsetInMinutes
    
+
    Timezone offset in minutes.
    
+
    By default, the date picker will use the device's timezone. With this parameter, it is possible to force a certain timezone offset. For instance, to show times in Pacific Standard Time, pass -7 * 60.
    
+

    Debugging
    Enabling Keyboard Shortcuts
    
+
    React Native supports a few keyboard shortcuts in the iOS Simulator. They are described below. To enable them, open the Hardware menu, select Keyboard, and make sure that "Connect Hardware Keyboard" is checked.
    
+
    Accessing the In-App Developer Menu
    
+
    You can access the developer menu by shaking your device or by selecting "Shake Gesture" inside the Hardware menu in the iOS Simulator. You can also use the ⌘D keyboard shortcut when your app is running in the iOS Simulator, or ⌘M when running in an Android emulator on Mac OS and Ctrl+M on Windows and Linux. Alternatively for Android, you can run the command adb shell input keyevent 82 to open the dev menu (82 being the Menu key code).
    
+
    
+
    
+
    The Developer Menu is disabled in release (production) builds.
    
+
    
+
    Reloading JavaScript
    
+
    Instead of recompiling your app every time you make a change, you can reload your app's JavaScript code instantly. To do so, select "Reload" from the Developer Menu. You can also press ⌘R in the iOS Simulator, or tap R twice on Android emulators.
    
+
    Automatic reloading
    
+
    You can speed up your development times by having your app reload automatically any time your code changes. Automatic reloading can be enabled by selecting "Enable Live Reload" from the Developer Menu.
    
+
    You may even go a step further and keep your app running as new versions of your files are injected into the JavaScript bundle automatically by enabling Hot Reloading from the Developer Menu. This will allow you to persist the app's state through reloads.
    
+
    
+
    There are some instances where hot reloading cannot be implemented perfectly. If you run into any issues, use a full reload to reset your app.
    
+
    
+
    You will need to rebuild your app for changes to take effect in certain situations:
    
+
      
+
    • You have added new resources to your native app's bundle, such as an image in Images.xcassets on iOS or the res/drawable folder on Android.
      • 
+
    • You have modified native code (Objective-C/Swift on iOS or Java/C++ on Android).
      • 
+
    
+
    In-app Errors and Warnings
    
+
    Errors and warnings are displayed inside your app in development builds.
    
+
    Errors
    
+
    In-app errors are displayed in a full screen alert with a red background inside your app. This screen is known as a RedBox. You can use console.error() to manually trigger one.
    
+
    Warnings
    
+
    Warnings will be displayed on screen with a yellow background. These alerts are known as YellowBoxes. Click on the alerts to show more information or to dismiss them.
    
+
    As with a RedBox, you can use console.warn() to trigger a YellowBox.
    
+
    YellowBoxes can be disabled during development by using console.disableYellowBox = true;. Specific warnings can be ignored programmatically by setting an array of prefixes that should be ignored:
    
+
    import {YellowBox} from 'react-native';
+YellowBox.ignoreWarnings(['Warning: ...']);
+
    
+
    In CI/Xcode, YellowBoxes can also be disabled by setting the IS_TESTING environment variable.
    
+
    
+
    RedBoxes and YellowBoxes are automatically disabled in release (production) builds.
    
+
    
+
    Chrome Developer Tools
    
+
    To debug the JavaScript code in Chrome, select "Debug JS Remotely" from the Developer Menu. This will open a new tab at http://localhost:8081/debugger-ui.
    
+
    Select Tools → Developer Tools from the Chrome Menu to open the Developer Tools. You may also access the DevTools using keyboard shortcuts (⌘⌥I on macOS, Ctrl Shift I on Windows). You may also want to enable Pause On Caught Exceptions for a better debugging experience.
    
+
    
+
    Note: the React Developer Tools Chrome extension does not work with React Native, but you can use its standalone version instead. Read this section to learn how.
    
+
    
+
    Debugging using a custom JavaScript debugger
    
+
    To use a custom JavaScript debugger in place of Chrome Developer Tools, set the REACT_DEBUGGER environment variable to a command that will start your custom debugger. You can then select "Debug JS Remotely" from the Developer Menu to start debugging.
    
+
    The debugger will receive a list of all project roots, separated by a space. For example, if you set REACT_DEBUGGER="node /path/to/launchDebugger.js --port 2345 --type ReactNative", then the command node /path/to/launchDebugger.js --port 2345 --type ReactNative /path/to/reactNative/app will be used to start your debugger.
    
+
    
+
    Custom debugger commands executed this way should be short-lived processes, and they shouldn't produce more than 200 kilobytes of output.
    
+
    
+
    Safari Developer Tools
    
+
    You can use Safari to debug the iOS version of your app without having to enable "Debug JS Remotely".
    
+
      
+
    • Enable Develop menu in Safari: Preferences → Advanced → Select "Show Develop menu in menu bar"
      • 
+
    • Select your app's JSContext: Develop → Simulator → JSContext
      • 
+
    • Safari's Web Inspector should open which has a Console and a Debugger
      • 
+
    
+
    However, there are some disadvantages:
    
+
      
+
    1. No sourcemaps when debugging
      2. 
+
    2. Every time the app is reloaded (using live reload, or by manually reloading), a new JSContext is created. Choosing "Automatically Show Web Inspectors for JSContexts" saves you from having to select the latest JSContext manually.
      3. 
+
    
+
    React Developer Tools
    
+
    You can use the standalone version of React Developer Tools to debug the React component hierarchy. To use it, install the react-devtools package globally:
    
+
    npm install -g react-devtools
+
    
+
    Now run react-devtools from the terminal to launch the standalone DevTools app:
    
+
    react-devtools
+
    
+
    React DevTools
    
+
    It should connect to your simulator within a few seconds.
    
+
    
+
    Note: if you prefer to avoid global installations, you can add react-devtools as a project dependency. Add the react-devtools package to your project using npm install --save-dev react-devtools, then add "react-devtools": "react-devtools" to the scripts section in your package.json, and then run npm run react-devtools from your project folder to open the DevTools.
    
+
    
+
    Integration with React Native Inspector
    
+
    Open the in-app developer menu and choose "Toggle Inspector". It will bring up an overlay that lets you tap on any UI element and see information about it:
    
+
    React Native Inspector
    
+
    However, when react-devtools is running, Inspector will enter a special collapsed mode, and instead use the DevTools as primary UI. In this mode, clicking on something in the simulator will bring up the relevant components in the DevTools:
    
+
    React DevTools Inspector Integration
    
+
    You can choose "Toggle Inspector" in the same menu to exit this mode.
    
+
    Inspecting Component Instances
    
+
    When debugging JavaScript in Chrome, you can inspect the props and state of the React components in the browser console.
    
+
    First, follow the instructions for debugging in Chrome to open the Chrome console.
    
+
    Make sure that the dropdown in the top left corner of the Chrome console says debuggerWorker.js. This step is essential.
    
+
    Then select a React component in React DevTools. There is a search box at the top that helps you find one by name. As soon as you select it, it will be available as $r in the Chrome console, letting you inspect its props, state, and instance properties.
    
+
    React DevTools Chrome Console Integration
    
+
    Performance Monitor
    
+
    You can enable a performance overlay to help you debug performance problems by selecting "Perf Monitor" in the Developer Menu.
    
+
    
+
    Debugging in Ejected Apps
    
+
+
    Accessing console logs
    
+
    You can display the console logs for an iOS or Android app by using the following commands in a terminal while the app is running:
    
+
    $ react-native log-ios
+$ react-native log-android
+
    
+
    You may also access these through Debug → Open System Log... in the iOS Simulator or by running adb logcat *:S ReactNative:V ReactNativeJS:V in a terminal while an Android app is running on a device or emulator.
    
+
    
+
    If you're using Create React Native App or Expo CLI, console logs already appear in the same terminal output as the packager.
    
+
    
+
    Debugging on a device with Chrome Developer Tools
    
+
    
+
    If you're using Create React Native App or Expo CLI, this is configured for you already.
    
+
    
+
    On iOS devices, open the file RCTWebSocketExecutor.m and change "localhost" to the IP address of your computer, then select "Debug JS Remotely" from the Developer Menu.
    
+
    On Android 5.0+ devices connected via USB, you can use the adb command line tool to setup port forwarding from the device to your computer:
    
+
    adb reverse tcp:8081 tcp:8081
    
+
    Alternatively, select "Dev Settings" from the Developer Menu, then update the "Debug server host for device" setting to match the IP address of your computer.
    
+
    
+
    If you run into any issues, it may be possible that one of your Chrome extensions is interacting in unexpected ways with the debugger. Try disabling all of your extensions and re-enabling them one-by-one until you find the problematic extension.
    
+
    
+
    Debugging native code
    
+
    When working with native code, such as when writing native modules, you can launch the app from Android Studio or Xcode and take advantage of the native debugging features (setting up breakpoints, etc.) as you would in case of building a standard native app.

    Methods
    
+
    set()
    
+
    static set(dims)
+
    
+
    This should only be called from native code by sending the didUpdateDimensions event.
    
+
    @param {object} dims Simple string-keyed object of dimensions to set
    
+
    
+
    get()
    
+
    static get(dim)
+
    
+
    Initial dimensions are set before runApplication is called so they should be available before any other require's are run, but may be updated later.
    
+
    
+
    Note: Although dimensions are available immediately, they may change (e.g due to device rotation) so any rendering logic or styles that depend on these constants should try to call this function on every render, rather than caching the value (for example, using inline styles rather than setting a value in a StyleSheet).
    
+
    
+
    Example: var {height, width} = Dimensions.get('window');
    
+
    @param {string} dim Name of dimension as defined when calling set. @returns {Object?} Value for the dimension.
    
+
    
+
    For Android the window dimension will exclude the size used by the status bar (if not translucent) and bottom navigation bar
    
+

    Methods
    
+
    set()
    
+
    static set(dims)
+
    
+
    This should only be called from native code by sending the didUpdateDimensions event.
    
+
    @param {object} dims Simple string-keyed object of dimensions to set
    
+
    
+
    get()
    
+
    static get(dim)
+
    
+
    Initial dimensions are set before runApplication is called so they should be available before any other require's are run, but may be updated later.
    
+
    
+
    Note: Although dimensions are available immediately, they may change (e.g due to device rotation) so any rendering logic or styles that depend on these constants should try to call this function on every render, rather than caching the value (for example, using inline styles rather than setting a value in a StyleSheet).
    
+
    
+
    Example: var {height, width} = Dimensions.get('window');
    
+
    @param {string} dim Name of dimension as defined when calling set. @returns {Object?} Value for the dimension.
    
+
    
+
    For Android the window dimension will exclude the size used by the status bar (if not translucent) and bottom navigation bar
    
+
    
+
    
+
    addEventListener()
    
+
    static addEventListener(type, handler)
+
    
+
    Add an event handler. Supported events:
    
+
      
+
    • change: Fires when a property within the Dimensions object changes. The argument to the event handler is an object with window and screen properties whose values are the same as the return values of Dimensions.get('window') and Dimensions.get('screen'), respectively.

+Direct Manipulation · React Native

    Edit
    Direct Manipulation
    It is sometimes necessary to make changes directly to a component without using state/props to trigger a re-render of the entire subtree. When using React in the browser for example, you sometimes need to directly modify a DOM node, and the same is true for views in mobile apps. setNativeProps is the React Native equivalent to setting properties directly on a DOM node.
    
+
    
+
    Use setNativeProps when frequent re-rendering creates a performance bottleneck
    
+
    Direct manipulation will not be a tool that you reach for frequently; you will typically only be using it for creating continuous animations to avoid the overhead of rendering the component hierarchy and reconciling many views. setNativeProps is imperative and stores state in the native layer (DOM, UIView, etc.) and not within your React components, which makes your code more difficult to reason about. Before you use it, try to solve your problem with setState and shouldComponentUpdate.
    
+
    
+
    setNativeProps with TouchableOpacity
    
+
    TouchableOpacity uses setNativeProps internally to update the opacity of its child component:
    
+
    setOpacityTo(value) {
+  // Redacted: animation related code
+  this.refs[CHILD_REF].setNativeProps({
+    opacity: value
+  });
+},
+
    
+
    This allows us to write the following code and know that the child will have its opacity updated in response to taps, without the child having any knowledge of that fact or requiring any changes to its implementation:
    
+
    <TouchableOpacity onPress={this._handlePress}>
+  <View style={styles.button}>
+    <Text>Press me!</Text>
+  </View>
+</TouchableOpacity>
+
    
+
    Let's imagine that setNativeProps was not available. One way that we might implement it with that constraint is to store the opacity value in the state, then update that value whenever onPress is fired:
    
+
    constructor(props) {
+  super(props);
+  this.state = { myButtonOpacity: 1, };
+}
+
+render() {
+  return (
+    <TouchableOpacity onPress={() => this.setState({myButtonOpacity: 0.5})}
+                      onPressOut={() => this.setState({myButtonOpacity: 1})}>
+      <View style={[styles.button, {opacity: this.state.myButtonOpacity}]}>
+        <Text>Press me!</Text>
+      </View>
+    </TouchableOpacity>
+  )
+}
+
    
+
    This is computationally intensive compared to the original example - React needs to re-render the component hierarchy each time the opacity changes, even though other properties of the view and its children haven't changed. Usually this overhead isn't a concern but when performing continuous animations and responding to gestures, judiciously optimizing your components can improve your animations' fidelity.
    
+
    If you look at the implementation of setNativeProps in NativeMethodsMixin you will notice that it is a wrapper around RCTUIManager.updateView - this is the exact same function call that results from re-rendering - see receiveComponent in ReactNativeBaseComponent.js.
    
+
    Composite components and setNativeProps
    
+
    Composite components are not backed by a native view, so you cannot call setNativeProps on them. Consider this example:
    
+
    If you run this you will immediately see this error: Touchable child must either be native or forward setNativeProps to a native component. This occurs because MyButton isn't directly backed by a native view whose opacity should be set. You can think about it like this: if you define a component with createReactClass you would not expect to be able to set a style prop on it and have that work - you would need to pass the style prop down to a child, unless you are wrapping a native component. Similarly, we are going to forward setNativeProps to a native-backed child component.
    
+
    Forward setNativeProps to a child
    
+
    All we need to do is provide a setNativeProps method on our component that calls setNativeProps on the appropriate child with the given arguments.
    
+
    You can now use MyButton inside of TouchableOpacity! A sidenote for clarity: we used the ref callback syntax here, rather than the traditional string-based ref.
    
+
    You may have noticed that we passed all of the props down to the child view using {...this.props}. The reason for this is that TouchableOpacity is actually a composite component, and so in addition to depending on setNativeProps on its child, it also requires that the child perform touch handling. To do this, it passes on various props that call back to the TouchableOpacity component. TouchableHighlight, in contrast, is backed by a native view and only requires that we implement setNativeProps.
    
+
    setNativeProps to clear TextInput value
    
+
    Another very common use case of setNativeProps is to clear the value of a TextInput. The controlled prop of TextInput can sometimes drop characters when the bufferDelay is low and the user types very quickly. Some developers prefer to skip this prop entirely and instead use setNativeProps to directly manipulate the TextInput value when necessary. For example, the following code demonstrates clearing the input when you tap a button:
    
+
    Avoiding conflicts with the render function
    
+
    If you update a property that is also managed by the render function, you might end up with some unpredictable and confusing bugs because anytime the component re-renders and that property changes, whatever value was previously set from setNativeProps will be completely ignored and overridden.
    
+
    setNativeProps & shouldComponentUpdate
    
+
    By intelligently applying shouldComponentUpdate you can avoid the unnecessary overhead involved in reconciling unchanged component subtrees, to the point where it may be performant enough to use setState instead of setNativeProps.
    
+
    Other native methods
    
+
    The methods described here are available on most of the default components provided by React Native. Note, however, that they are not available on composite components that aren't directly backed by a native view. This will generally include most components that you define in your own app.
    
+
    measure(callback)
    
+
    Determines the location on screen, width, and height of the given view and returns the values via an async callback. If successful, the callback will be called with the following arguments:
    
+
      
+
    • x
      • 
+
    • y
      • 
+
    • width
      • 
+
    • height
      • 
+
    • pageX
      • 
+
    • pageY
      • 
+
    
+
    Note that these measurements are not available until after the rendering has been completed in native. If you need the measurements as soon as possible, consider using the onLayout prop instead.
    
+
    measureInWindow(callback)
    
+
    Determines the location of the given view in the window and returns the values via an async callback. If the React root view is embedded in another native view, this will give you the absolute coordinates. If successful, the callback will be called with the following arguments:
    
+
      
+
    • x
      • 
+
    • y
      • 
+
    • width
      • 
+
    • height
      • 
+
    
+
    measureLayout(relativeToNativeNode, onSuccess, onFail)
    
+
    Like measure(), but measures the view relative an ancestor, specified as relativeToNativeNode. This means that the returned x, y are relative to the origin x, y of the ancestor view.
    
+
    As always, to obtain a native node handle for a component, you can use findNodeHandle(component).
    
+
    import {findNodeHandle} from 'react-native';
+
    
+
    focus()
    
+
    Requests focus for the given input or view. The exact behavior triggered will depend on the platform and type of view.
    
+
    blur()
    
+
    Removes focus from an input or view. This is the opposite of focus().

    DrawerLayoutAndroid
    React component that wraps the platform DrawerLayout (Android only). The Drawer (typically used for navigation) is rendered with renderNavigationView and direct children are the main view (where your content goes). The navigation view is initially not visible on the screen, but can be pulled in from the side of the window specified by the drawerPosition prop and its width can be set by the drawerWidth prop.
    
+
    Example:
    
+
    render: function() {
+  var navigationView = (
+    <View style={{flex: 1, backgroundColor: '#fff'}}>
+      <Text style={{margin: 10, fontSize: 15, textAlign: 'left'}}>I'm in the Drawer!</Text>
+    </View>
+  );
+  return (
+    <DrawerLayoutAndroid
+      drawerWidth={300}
+      drawerPosition={DrawerLayoutAndroid.positions.Left}
+      renderNavigationView={() => navigationView}>
+      <View style={{flex: 1, alignItems: 'center'}}>
+        <Text style={{margin: 10, fontSize: 15, textAlign: 'right'}}>Hello</Text>

    DrawerLayoutAndroid
    React component that wraps the platform DrawerLayout (Android only). The Drawer (typically used for navigation) is rendered with renderNavigationView and direct children are the main view (where your content goes). The navigation view is initially not visible on the screen, but can be pulled in from the side of the window specified by the drawerPosition prop and its width can be set by the drawerWidth prop.
    
+
    Example:
    
+
    render: function() {
+  var navigationView = (
+    <View style={{flex: 1, backgroundColor: '#fff'}}>
+      <Text style={{margin: 10, fontSize: 15, textAlign: 'left'}}>I'm in the Drawer!</Text>
+    </View>
+  );
+  return (
+    <DrawerLayoutAndroid
+      drawerWidth={300}
+      drawerPosition={DrawerLayoutAndroid.positions.Left}
+      renderNavigationView={() => navigationView}>
+      <View style={{flex: 1, alignItems: 'center'}}>
+        <Text style={{margin: 10, fontSize: 15, textAlign: 'right'}}>Hello</Text>
+        <Text style={{margin: 10, fontSize: 15, textAlign: 'right'}}>World!</Text>
+      </View>
+    </DrawerLayoutAndroid>
+  );

    FlatList
    A performant interface for rendering simple, flat lists, supporting the most handy features:
    
+
      
+
    • Fully cross-platform.
      • 
+
    • Optional horizontal mode.
      • 
+
    • Configurable viewability callbacks.
      • 
+
    • Header support.
      • 
+
    • Footer support.
      • 
+
    • Separator support.
      • 
+
    • Pull to Refresh.
      • 
+
    • Scroll loading.
      • 
+
    • ScrollToIndex support.
      • 
+
    
+
    If you need section support, use <SectionList>.
    
+
    Minimal Example:
    
+
    <FlatList
+  data={[{key: 'a'}, {key: 'b'}]}
+  renderItem={({item}) => <Text>{item.key}</Text>}
+/>
+
    
+
    More complex, multi-select example demonstrating PureComponent usage for perf optimization and avoiding bugs.
    
+
      
+
    • By binding the onPressItem handler, the props will remain === and PureComponent will prevent wasteful re-renders unless the actual id, selected, or title props change, even if the components rendered in MyListItem did not have such optimizations.
      • 
+
    • By passing extraData={this.state} to FlatList we make sure FlatList itself will re-render when the state.selected changes. Without setting this prop, FlatList would not know it needs to re-render any items because it is also a PureComponent and the prop comparison will not show any changes.
      • 
+
    • keyExtractor tells the list to use the ids for the react keys instead of the default key property.
      • 
+
    
+
    class MyListItem extends React.PureComponent {
+  _onPress = () => {
+    this.props.onPressItem(this.props.id);

    This is a convenience wrapper around <VirtualizedList>, and thus inherits its props (as well as those of <ScrollView>) that aren't explicitly listed here, along with the following caveats:
    
+
      
+
    • Internal state is not preserved when content scrolls out of the render window. Make sure all your data is captured in the item data or external stores like Flux, Redux, or Relay.
      • 
+
    • This is a PureComponent which means that it will not re-render if props remain shallow- equal. Make sure that everything your renderItem function depends on is passed as a prop (e.g. extraData) that is not === after updates, otherwise your UI may not update on changes. This includes the data prop and parent component state.
      • 
+
    • In order to constrain memory and enable smooth scrolling, content is rendered asynchronously offscreen. This means it's possible to scroll faster than the fill rate and momentarily see blank content. This is a tradeoff that can be adjusted to suit the needs of each application, and we are working on improving it behind the scenes.
      • 
+
    • By default, the list looks for a key prop on each item and uses that for the React key. Alternatively, you can provide a custom keyExtractor prop.
      • 
+
    
+
    Also inherits ScrollView Props, unless it is nested in another FlatList of same orientation.

    Props
    
+
    renderItem
    
+
    renderItem({ item: Object, index: number, separators: { highlight: Function, unhighlight: Function, updateProps: Function(select: string, newProps: Object) } }) => ?React.Element
+
    
+
    Takes an item from data and renders it into the list.
    
+
    Provides additional metadata like index if you need it, as well as a more generic separators.updateProps function which let you set whatever props you want to change the rendering of either the leading separator or trailing separator in case the more common highlight and unhighlight (which set the highlighted: boolean prop) are insufficient for your use case.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionYes
    
+
    Example usage:
    
+
    <FlatList
+  ItemSeparatorComponent={Platform.OS !== 'android' && ({highlighted}) => (
+    <View style={[style.separator, highlighted && {marginLeft: 0}]} />
+  )}
+  data={[{title: 'Title Text', key: 'item1'}]}
+  renderItem={({item, separators}) => (
+    <TouchableHighlight
+      onPress={() => this._onPress(item)}
+      onShowUnderlay={separators.highlight}
+      onHideUnderlay={separators.unhighlight}>
+      <View style={{backgroundColor: 'white'}}>
+        <Text>{item.title}</Text>
+      </View>
+    </TouchableHighlight>
+  )}
+/>
+
    
+
    
+
    data
    
+
    For simplicity, data is just a plain array. If you want to use something else, like an immutable list, use the underlying VirtualizedList directly.
    
+
+
+
+
+
+
+
+
    TypeRequired
    arrayYes
    
+
    
+
    ItemSeparatorComponent
    
+
    Rendered in between each item, but not at the top or bottom. By default, highlighted and leadingItem props are provided. renderItem provides separators.highlight/unhighlight which will update the highlighted prop, but you can also add custom props with separators.updateProps.
    
+
+
+
+
+
+
+
+
    TypeRequired
    componentNo
    
+
    
+
    ListEmptyComponent
    
+
    Rendered when the list is empty. Can be a React Component Class, a render function, or a rendered element.
    
+
+
+
+
+
+
+
+
    TypeRequired
    component, function, elementNo
    
+
    
+
    ListFooterComponent
    
+
    Rendered at the bottom of all the items. Can be a React Component Class, a render function, or a rendered element.
    
+
+
+
+
+
+
+
+
    TypeRequired
    component, function, elementNo
    
+
    
+
    ListHeaderComponent
    
+
    Rendered at the top of all the items. Can be a React Component Class, a render function, or a rendered element.
    
+
+
+
+
+
+
+
+
    TypeRequired
    component, function, elementNo
    
+
    
+
    columnWrapperStyle
    
+
    Optional custom style for multi-item rows generated when numColumns > 1.
    
+
+
+
+
+
+
+
+
    TypeRequired
    style objectNo
    
+
    
+
    extraData
    
+
    A marker property for telling the list to re-render (since it implements PureComponent). If any of your renderItem, Header, Footer, etc. functions depend on anything outside of the data prop, stick it here and treat it immutably.
    
+
+
+
+
+
+
+
+
    TypeRequired
    anyNo
    
+
    
+
    getItemLayout
    
+
    (data, index) => {length: number, offset: number, index: number}
+
    
+
    getItemLayout is an optional optimization that let us skip the measurement of dynamic content if you know the height of items ahead of time. getItemLayout is both efficient and easy to use if you have fixed height items, for example:
    
+
      getItemLayout={(data, index) => (
+    {length: ITEM_HEIGHT, offset: ITEM_HEIGHT * index, index}
+  )}
+
    
+
    Adding getItemLayout can be a great performance boost for lists of several hundred items. Remember to include separator length (height or width) in your offset calculation if you specify ItemSeparatorComponent.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    horizontal
    
+
    If true, renders items next to each other horizontally instead of stacked vertically.
    
+
+
+
+
+
+
+
+
    TypeRequired
    booleanNo
    
+
    
+
    initialNumToRender
    
+
    How many items to render in the initial batch. This should be enough to fill the screen but not much more. Note these items will never be unmounted as part of the windowed rendering in order to improve perceived performance of scroll-to-top actions.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberNo
    
+
    
+
    initialScrollIndex
    
+
    Instead of starting at the top with the first item, start at initialScrollIndex. This disables the "scroll to top" optimization that keeps the first initialNumToRender items always rendered and immediately renders the items starting at this initial index. Requires getItemLayout to be implemented.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberNo
    
+
    
+
    inverted

    TypeRequired
    booleanNo
    
+
    
+
    keyExtractor
    
+
    (item: object, index: number) => string;
+
    
+
    Used to extract a unique key for a given item at the specified index. Key is used for caching and as the react key to track item re-ordering. The default extractor checks item.key, then falls back to using the index, like React does.
    
+

+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    numColumns
    
+
    Multiple columns can only be rendered with horizontal={false} and will zig-zag like a flexWrap layout. Items should all be the same height - masonry layouts are not supported.

+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onEndReachedThreshold
    
+
    How far from the end (in units of visible length of the list) the bottom edge of the list must be from the end of the content to trigger the onEndReached callback. Thus a value of 0.5 will trigger onEndReached when the end of the content is within half the visible length of the list.

+
+
+
+
+
+
+
+
    TypeRequired
    ViewabilityConfigNo
    
+
    viewabilityConfig takes a type ViewabilityConfig an object with following properties
    
+
+
+
+
+
+
+
+
+
+
+
    PropertyRequiredType
    minimumViewTimeNonumber
    viewAreaCoveragePercentThresholdNonumber
    itemVisiblePercentThresholdNonumber
    waitForInteractionNoboolean
    
+
    At least one of the viewAreaCoveragePercentThreshold or itemVisiblePercentThreshold is required. This needs to be done in the constructor to avoid following error (ref):
    
+
      Error: Changing viewabilityConfig on the fly is not supported`
+
    
+
    constructor (props) {
+  super(props)
+
+  this.viewabilityConfig = {
+      waitForInteraction: true,
+      viewAreaCoveragePercentThreshold: 95
+  }
+}
+
    
+
    <FlatList
+    viewabilityConfig={this.viewabilityConfig}
+  ...
+
    
+
    minimumViewTime
    
+
    Minimum amount of time (in milliseconds) that an item must be physically viewable before the viewability callback will be fired. A high number means that scrolling through content without stopping will not mark the content as viewable.
    
+
    viewAreaCoveragePercentThreshold
    
+
    Percent of viewport that must be covered for a partially occluded item to count as "viewable", 0-100. Fully visible items are always considered viewable. A value of 0 means that a single pixel in the viewport makes the item viewable, and a value of 100 means that an item must be either entirely visible or cover the entire viewport to count as viewable.
    
+
    itemVisiblePercentThreshold
    
+
    Similar to viewAreaPercentThreshold, but considers the percent of the item that is visible, rather than the fraction of the viewable area it covers.
    
+
    waitForInteraction
    
+
    Nothing is considered viewable until the user scrolls or recordInteraction is called after render.
    
+
    
+
    viewabilityConfigCallbackPairs
    
+
    List of ViewabilityConfig/onViewableItemsChanged pairs. A specific onViewableItemsChanged will be called when its corresponding ViewabilityConfig's conditions are met. See ViewabilityHelper.js for flow type and further documentation.
    
+
+
+

    FlatList
    A performant interface for rendering simple, flat lists, supporting the most handy features:
    
+
      
+
    • Fully cross-platform.
      • 
+
    • Optional horizontal mode.
      • 
+
    • Configurable viewability callbacks.
      • 
+
    • Header support.
      • 
+
    • Footer support.
      • 
+
    • Separator support.
      • 
+
    • Pull to Refresh.
      • 
+
    • Scroll loading.
      • 
+
    • ScrollToIndex support.
      • 
+
    
+
    If you need section support, use <SectionList>.
    
+
    Minimal Example:
    
+
    <FlatList
+  data={[{key: 'a'}, {key: 'b'}]}
+  renderItem={({item}) => <Text>{item.key}</Text>}
+/>
+
    
+
    More complex, multi-select example demonstrating PureComponent usage for perf optimization and avoiding bugs.
    
+
      
+
    • By binding the onPressItem handler, the props will remain === and PureComponent will prevent wasteful re-renders unless the actual id, selected, or title props change, even if the components rendered in MyListItem did not have such optimizations.
      • 
+
    • By passing extraData={this.state} to FlatList we make sure FlatList itself will re-render when the state.selected changes. Without setting this prop, FlatList would not know it needs to re-render any items because it is also a PureComponent and the prop comparison will not show any changes.
      • 
+
    • keyExtractor tells the list to use the ids for the react keys instead of the default key property.
      • 
+
    
+
    class MyListItem extends React.PureComponent {
+  _onPress = () => {
+    this.props.onPressItem(this.props.id);
+  };
+
+  render() {
+    const textColor = this.props.selected ? 'red' : 'black';
+    return (
+      <TouchableOpacity onPress={this._onPress}>
+        <View>
+          <Text style={{color: textColor}}>{this.props.title}</Text>
+        </View>
+      </TouchableOpacity>
+    );
+  }
+}
+
+class MultiSelectList extends React.PureComponent {
+  state = {selected: (new Map(): Map<string, boolean>)};
+
+  _keyExtractor = (item, index) => item.id;
+
+  _onPressItem = (id: string) => {
+    // updater functions are preferred for transactional updates
+    this.setState((state) => {
+      // copy the map rather than modifying state.
+      const selected = new Map(state.selected);
+      selected.set(id, !selected.get(id)); // toggle
+      return {selected};
+    });
+  };
+
+  _renderItem = ({item}) => (
+    <MyListItem
+      id={item.id}
+      onPressItem={this._onPressItem}

    This is a convenience wrapper around <VirtualizedList>, and thus inherits its props (as well as those of <ScrollView>) that aren't explicitly listed here, along with the following caveats:
    
+
      
+
    • Internal state is not preserved when content scrolls out of the render window. Make sure all your data is captured in the item data or external stores like Flux, Redux, or Relay.
      • 
+
    • This is a PureComponent which means that it will not re-render if props remain shallow- equal. Make sure that everything your renderItem function depends on is passed as a prop (e.g. extraData) that is not === after updates, otherwise your UI may not update on changes. This includes the data prop and parent component state.
      • 
+
    • In order to constrain memory and enable smooth scrolling, content is rendered asynchronously offscreen. This means it's possible to scroll faster than the fill rate and momentarily see blank content. This is a tradeoff that can be adjusted to suit the needs of each application, and we are working on improving it behind the scenes.
      • 
+
    • By default, the list looks for a key prop on each item and uses that for the React key. Alternatively, you can provide a custom keyExtractor prop.
      •

    Also inherits ScrollView Props, unless it is nested in another FlatList of same orientation.

    <FlatList
+  ItemSeparatorComponent={Platform.OS !== 'android' && ({highlighted}) => (
+    <View style={[style.separator, highlighted && {marginLeft: 0}]} />
+  )}
+  data={[{title: 'Title Text', key: 'item1'}]}
+  renderItem={({item, separators}) => (
+    <TouchableHighlight
+      onPress={() => this._onPress(item)}
+      onShowUnderlay={separators.highlight}
+      onHideUnderlay={separators.unhighlight}>
+      <View style={{backgroundColor: 'white'}}>
+        <Text>{item.title}</Text>
+      </View>
+    </TouchableHighlight>
+  )}
+/>
+
    
+
    
+
    data
    
+
    For simplicity, data is just a plain array. If you want to use something else, like an immutable list, use the underlying VirtualizedList directly.
    
+
+
+
+
+
+
+
+
    TypeRequired
    arrayYes
    
+
    
+
    ItemSeparatorComponent
    
+
    Rendered in between each item, but not at the top or bottom. By default, highlighted and leadingItem props are provided. renderItem provides separators.highlight/unhighlight which will update the highlighted prop, but you can also add custom props with separators.updateProps.
    
+
+
+
+
+
+
+
+
    TypeRequired
    componentNo
    
+
    
+
    ListEmptyComponent
    
+
    Rendered when the list is empty. Can be a React Component Class, a render function, or a rendered element.
    
+
+
+
+
+
+
+
+
    TypeRequired
    component, function, elementNo
    
+
    
+
    ListFooterComponent
    
+
    Rendered at the bottom of all the items. Can be a React Component Class, a render function, or a rendered element.
    
+
+
+
+
+
+
+
+
    TypeRequired
    component, function, elementNo
    
+
    
+
    ListHeaderComponent
    
+
    Rendered at the top of all the items. Can be a React Component Class, a render function, or a rendered element.
    
+
+
+
+
+
+
+
+
    TypeRequired
    component, function, elementNo
    
+
    
+
    columnWrapperStyle
    
+
    Optional custom style for multi-item rows generated when numColumns > 1.
    
+
+
+
+
+
+
+
+
    TypeRequired
    style objectNo
    
+
    
+
    extraData
    
+
    A marker property for telling the list to re-render (since it implements PureComponent). If any of your renderItem, Header, Footer, etc. functions depend on anything outside of the data prop, stick it here and treat it immutably.
    
+
+
+
+
+
+
+
+
    TypeRequired
    anyNo
    
+
    
+
    getItemLayout
    
+
    (data, index) => {length: number, offset: number, index: number}
+
    
+
    getItemLayout is an optional optimization that let us skip the measurement of dynamic content if you know the height of items ahead of time. getItemLayout is both efficient and easy to use if you have fixed height items, for example:
    
+
      getItemLayout={(data, index) => (
+    {length: ITEM_HEIGHT, offset: ITEM_HEIGHT * index, index}
+  )}
+
    
+
    Adding getItemLayout can be a great performance boost for lists of several hundred items. Remember to include separator length (height or width) in your offset calculation if you specify ItemSeparatorComponent.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    horizontal
    
+
    If true, renders items next to each other horizontally instead of stacked vertically.
    
+
+
+
+
+
+
+
+
    TypeRequired
    booleanNo
    
+
    
+
    initialNumToRender
    
+
    How many items to render in the initial batch. This should be enough to fill the screen but not much more. Note these items will never be unmounted as part of the windowed rendering in order to improve perceived performance of scroll-to-top actions.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberNo
    
+
    
+
    initialScrollIndex
    
+
    Instead of starting at the top with the first item, start at initialScrollIndex. This disables the "scroll to top" optimization that keeps the first initialNumToRender items always rendered and immediately renders the items starting at this initial index. Requires getItemLayout to be implemented.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberNo
    
+
    
+
    inverted
    
+
    Reverses the direction of scroll. Uses scale transforms of -1.
    
+
+
+
+
+
+
+
+
    TypeRequired
    booleanNo
    
+
    
+
    keyExtractor
    
+
    (item: object, index: number) => string;
+
    
+
    Used to extract a unique key for a given item at the specified index. Key is used for caching and as the react key to track item re-ordering. The default extractor checks item.key, then falls back to using the index, like React does.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    numColumns
    
+
    Multiple columns can only be rendered with horizontal={false} and will zig-zag like a flexWrap layout. Items should all be the same height - masonry layouts are not supported.
    
+
+
+
+
+
+

    TypeRequired
    numberNo
    
+
    
+
    onEndReached

+
    Called once when the scroll position gets within onEndReachedThreshold of the rendered content.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onEndReachedThreshold
    
+
    How far from the end (in units of visible length of the list) the bottom edge of the list must be from the end of the content to trigger the onEndReached callback. Thus a value of 0.5 will trigger onEndReached when the end of the content is within half the visible length of the list.

    TypeRequired
    numberNo

+  }) => void
+
    
+
    Called when the viewability of rows changes, as defined by the viewabilityConfig prop.

    See ViewabilityHelper.js for flow type and further documentation.
    
+
+
+
+
+
+
+
+
    TypeRequired
    ViewabilityConfigNo
    
+
    viewabilityConfig takes a type ViewabilityConfig an object with following properties
    
+
+
+
+
+
+
+
+
+
+
+
    PropertyRequiredType
    minimumViewTimeNonumber
    viewAreaCoveragePercentThresholdNonumber
    itemVisiblePercentThresholdNonumber
    waitForInteractionNoboolean
    
+
    At least one of the viewAreaCoveragePercentThreshold or itemVisiblePercentThreshold is required. This needs to be done in the constructor to avoid following error (ref):
    
+
      Error: Changing viewabilityConfig on the fly is not supported`
+
    
+
    constructor (props) {
+  super(props)
+
+  this.viewabilityConfig = {
+      waitForInteraction: true,
+      viewAreaCoveragePercentThreshold: 95
+  }
+}
+
    
+
    <FlatList
+    viewabilityConfig={this.viewabilityConfig}
+  ...
+
    
+
    minimumViewTime
    
+
    Minimum amount of time (in milliseconds) that an item must be physically viewable before the viewability callback will be fired. A high number means that scrolling through content without stopping will not mark the content as viewable.
    
+
    viewAreaCoveragePercentThreshold
    
+
    Percent of viewport that must be covered for a partially occluded item to count as "viewable", 0-100. Fully visible items are always considered viewable. A value of 0 means that a single pixel in the viewport makes the item viewable, and a value of 100 means that an item must be either entirely visible or cover the entire viewport to count as viewable.
    
+
    itemVisiblePercentThreshold
    
+
    Similar to viewAreaPercentThreshold, but considers the percent of the item that is visible, rather than the fraction of the viewable area it covers.
    
+
    waitForInteraction
    
+
    Nothing is considered viewable until the user scrolls or recordInteraction is called after render.
    
+
    
+
    viewabilityConfigCallbackPairs
    
+
    List of ViewabilityConfig/onViewableItemsChanged pairs. A specific onViewableItemsChanged will be called when its corresponding ViewabilityConfig's conditions are met. See ViewabilityHelper.js for flow type and further documentation.
    
+
+
+
+
+
+
+

    Layout with Flexbox
    A component can specify the layout of its children using the flexbox algorithm. Flexbox is designed to provide a consistent layout on different screen sizes.
    
+
    You will normally use a combination of flexDirection, alignItems, and justifyContent to achieve the right layout.
    
+
    
+
    Flexbox works the same way in React Native as it does in CSS on the web, with a few exceptions. The defaults are different, with flexDirection defaulting to column instead of row, and the flex parameter only supporting a single number.
    
+
    
+
    Flex Direction
    
+
    Adding flexDirection to a component's style determines the primary axis of its layout. Should the children be organized horizontally (row) or vertically (column)? The default is column.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View } from 'react-native';
+
+export default class FlexDirectionBasics extends Component {
+  render() {
+    return (
+      // Try setting `flexDirection` to `column`.
+      <View style={{flex: 1, flexDirection: 'row'}}>
+        <View style={{width: 50, height: 50, backgroundColor: 'powderblue'}} />
+        <View style={{width: 50, height: 50, backgroundColor: 'skyblue'}} />
+        <View style={{width: 50, height: 50, backgroundColor: 'steelblue'}} />
+      </View>
+    );
+  }
+};
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => FlexDirectionBasics);
+
    
+
+
    Justify Content
    
+
    Adding justifyContent to a component's style determines the distribution of children along the primary axis. Should children be distributed at the start, the center, the end, or spaced evenly? Available options are flex-start, center, flex-end, space-around, space-between and space-evenly.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View } from 'react-native';
+
+export default class JustifyContentBasics extends Component {
+  render() {
+    return (
+      // Try setting `justifyContent` to `center`.
+      // Try setting `flexDirection` to `row`.
+      <View style={{
+        flex: 1,
+        flexDirection: 'column',
+        justifyContent: 'space-between',
+      }}>
+        <View style={{width: 50, height: 50, backgroundColor: 'powderblue'}} />
+        <View style={{width: 50, height: 50, backgroundColor: 'skyblue'}} />
+        <View style={{width: 50, height: 50, backgroundColor: 'steelblue'}} />
+      </View>
+    );
+  }
+};
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => JustifyContentBasics);
+
    
+
+
    Align Items
    
+
    Adding alignItems to a component's style determines the alignment of children along the secondary axis (if the primary axis is row, then the secondary is column, and vice versa). Should children be aligned at the start, the center, the end, or stretched to fill? Available options are flex-start, center, flex-end, and stretch.
    
+
    
+
    For stretch to have an effect, children must not have a fixed dimension along the secondary axis. In the following example, setting alignItems: stretch does nothing until the width: 50 is removed from the children.
    
+
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View } from 'react-native';
+
+export default class AlignItemsBasics extends Component {
+  render() {
+    return (
+      // Try setting `alignItems` to 'flex-start'
+      // Try setting `justifyContent` to `flex-end`.
+      // Try setting `flexDirection` to `row`.
+      <View style={{
+        flex: 1,
+        flexDirection: 'column',
+        justifyContent: 'center',
+        alignItems: 'stretch',
+      }}>
+        <View style={{width: 50, height: 50, backgroundColor: 'powderblue'}} />
+        <View style={{height: 50, backgroundColor: 'skyblue'}} />
+        <View style={{height: 100, backgroundColor: 'steelblue'}} />
+      </View>
+    );
+  }
+};
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => AlignItemsBasics);
+

    Going Deeper
    
+
    We've covered the basics, but there are many other styles you may need for layouts. The full list of props that control layout is documented here.
    
+
    We're getting close to being able to build a real application. One thing we are still missing is a way to take user input, so let's move on to learn how to handle text input with the TextInput component.

    For stretch to have an effect, children must not have a fixed dimension along the secondary axis. In the following example, setting alignItems: stretch does nothing until the width: 50 is removed from the children.
    
+
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View } from 'react-native';
+
+export default class AlignItemsBasics extends Component {
+  render() {
+    return (
+      // Try setting `alignItems` to 'flex-start'
+      // Try setting `justifyContent` to `flex-end`.
+      // Try setting `flexDirection` to `row`.
+      <View style={{
+        flex: 1,
+        flexDirection: 'column',
+        justifyContent: 'center',
+        alignItems: 'stretch',
+      }}>
+        <View style={{width: 50, height: 50, backgroundColor: 'powderblue'}} />
+        <View style={{height: 50, backgroundColor: 'skyblue'}} />
+        <View style={{height: 100, backgroundColor: 'steelblue'}} />
+      </View>
+    );
+  }
+};
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => AlignItemsBasics);

    Going Deeper
    
+
    We've covered the basics, but there are many other styles you may need for layouts. The full list of props that control layout is documented here.
    
+
    We're getting close to being able to build a real application. One thing we are still missing is a way to take user input, so let's move on to learn how to handle text input with the TextInput component.

    Geolocation
    The Geolocation API extends the Geolocation web spec.
    
+
    As a browser polyfill, this API is available through the navigator.geolocation global - you do not need to import it.
    
+
    On Android, this uses the android.location API. This API is not recommended by Google because it is less accurate and slower than the recommended Google Location Services API. In order to use it with React Native, use the react-native-geolocation-service module.
    
+
    Configuration and Permissions
    
+
+
    iOS
    
+
    You need to include the NSLocationWhenInUseUsageDescription key in Info.plist to enable geolocation when using the app. Geolocation is enabled by default when you create a project with react-native init.
    
+
    In order to enable geolocation in the background, you need to include the 'NSLocationAlwaysUsageDescription' key in Info.plist and add location as a background mode in the 'Capabilities' tab in Xcode.
    
+
    If you are using CocoaPods for React Native, make sure to include the RCTGeolocation sub-podspec.
    
+
    Android
    
+
    To request access to location, you need to add the following line to your app's AndroidManifest.xml:
    
+
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    
+
    Android API >= 18 Positions will also contain a mocked boolean to indicate if position was created from a mock provider.
    
+
    
+  Android API >= 23 Requires an additional step to check for, and request
+  the ACCESS_FINE_LOCATION permission using
+  the PermissionsAndroid API.
+  Failure to do so may result in a hard crash.
+

    Edit
    Gesture Responder System
    The gesture responder system manages the lifecycle of gestures in your app. A touch can go through several phases as the app determines what the user's intention is. For example, the app needs to determine if the touch is scrolling, sliding on a widget, or tapping. This can even change during the duration of a touch. There can also be multiple simultaneous touches.
    
+
    The touch responder system is needed to allow components to negotiate these touch interactions without any additional knowledge about their parent or child components.
    
+
    Best Practices
    
+
    To make your app feel great, every action should have the following attributes:
    
+
      
+
    • Feedback/highlighting- show the user what is handling their touch, and what will happen when they release the gesture
      • 
+
    • Cancel-ability- when making an action, the user should be able to abort it mid-touch by dragging their finger away
      • 
+
    
+
    These features make users more comfortable while using an app, because it allows people to experiment and interact without fear of making mistakes.
    
+
    TouchableHighlight and Touchable*
    
+
    The responder system can be complicated to use. So we have provided an abstract Touchable implementation for things that should be "tappable". This uses the responder system and allows you to easily configure tap interactions declaratively. Use TouchableHighlight anywhere where you would use a button or link on web.
    
+
    Responder Lifecycle
    
+
    A view can become the touch responder by implementing the correct negotiation methods. There are two methods to ask the view if it wants to become responder:
    
+
      
+
    • View.props.onStartShouldSetResponder: (evt) => true, - Does this view want to become responder on the start of a touch?
      • 
+
    • View.props.onMoveShouldSetResponder: (evt) => true, - Called for every touch move on the View when it is not the responder: does this view want to "claim" touch responsiveness?
      • 
+
    
+
    If the View returns true and attempts to become the responder, one of the following will happen:
    
+
      
+
    • View.props.onResponderGrant: (evt) => {} - The View is now responding for touch events. This is the time to highlight and show the user what is happening
      • 
+
    • View.props.onResponderReject: (evt) => {} - Something else is the responder right now and will not release it
      • 
+
    
+
    If the view is responding, the following handlers can be called:
    
+
      
+
    • View.props.onResponderMove: (evt) => {} - The user is moving their finger
      • 
+
    • View.props.onResponderRelease: (evt) => {} - Fired at the end of the touch, ie "touchUp"
      • 
+
    • View.props.onResponderTerminationRequest: (evt) => true - Something else wants to become responder. Should this view release the responder? Returning true allows release
      • 
+
    • View.props.onResponderTerminate: (evt) => {} - The responder has been taken from the View. Might be taken by other views after a call to onResponderTerminationRequest, or might be taken by the OS without asking (happens with control center/ notification center on iOS)
      • 
+
    
+
    evt is a synthetic touch event with the following form:
    
+
      
+
    • nativeEvent
+
        
+
      • changedTouches - Array of all touch events that have changed since the last event
        • 
+
      • identifier - The ID of the touch
        • 
+
      • locationX - The X position of the touch, relative to the element
        • 
+
      • locationY - The Y position of the touch, relative to the element
        • 
+
      • pageX - The X position of the touch, relative to the root element
        • 
+
      • pageY - The Y position of the touch, relative to the root element
        • 
+
      • target - The node id of the element receiving the touch event
        • 
+
      • timestamp - A time identifier for the touch, useful for velocity calculation
        • 
+
      • touches - Array of all current touches on the screen
        • 
+
      • 
+
    
+
    Capture ShouldSet Handlers
    
+
    onStartShouldSetResponder and onMoveShouldSetResponder are called with a bubbling pattern, where the deepest node is called first. That means that the deepest component will become responder when multiple Views return true for *ShouldSetResponder handlers. This is desirable in most cases, because it makes sure all controls and buttons are usable.
    
+
    However, sometimes a parent will want to make sure that it becomes responder. This can be handled by using the capture phase. Before the responder system bubbles up from the deepest component, it will do a capture phase, firing on*ShouldSetResponderCapture. So if a parent View wants to prevent the child from becoming responder on a touch start, it should have a onStartShouldSetResponderCapture handler which returns true.
    
+
      
+
    • View.props.onStartShouldSetResponderCapture: (evt) => true,
      • 
+
    • View.props.onMoveShouldSetResponderCapture: (evt) => true,
      • 
+
    
+

    Capture ShouldSet Handlers
    
+
    onStartShouldSetResponder and onMoveShouldSetResponder are called with a bubbling pattern, where the deepest node is called first. That means that the deepest component will become responder when multiple Views return true for *ShouldSetResponder handlers. This is desirable in most cases, because it makes sure all controls and buttons are usable.
    
+
    However, sometimes a parent will want to make sure that it becomes responder. This can be handled by using the capture phase. Before the responder system bubbles up from the deepest component, it will do a capture phase, firing on*ShouldSetResponderCapture. So if a parent View wants to prevent the child from becoming responder on a touch start, it should have a onStartShouldSetResponderCapture handler which returns true.
    
+
      
+
    • View.props.onStartShouldSetResponderCapture: (evt) => true,
      • 
+
    • View.props.onMoveShouldSetResponderCapture: (evt) => true,
      • 
+
    
+

    Getting Started
    
+
    This page will help you install and build your first React Native app. If you already have React Native installed, you can skip ahead to the Tutorial.
    
+
    
+  
      
+    
+    
+  
    
+
    
+
    
+
    Expo is the easiest way to start building a new React Native application. It allows you to start a project without installing or configuring any tools to build native code - no Xcode or Android Studio installation required (see Caveats).
    
+
    Assuming that you have Node 8+ installed, you can use npm to install the Expo CLI command line utility:
    
+
    npm install -g expo-cli
+
    
+
    Then run the following commands to create a new React Native project called "AwesomeProject":
    
+
    expo init AwesomeProject
+
+cd AwesomeProject
+npm start #you can also use: expo start
+
    
+
    This will start a development server for you.
    
+
    Running your React Native application
    
+
    Install the Expo client app on your iOS or Android phone and connect to the same wireless network as your computer. On Android, use the Expo app to scan the QR code from your terminal to open your project. On iOS, follow on-screen instructions to get a link.
    
+
    Modifying your app
    
+
    Now that you have successfully run the app, let's modify it. Open App.js in your text editor of choice and edit some lines. The application should reload automatically once you save your changes.
    
+
    That's it!
    
+
    Congratulations! You've successfully run and modified your first React Native app.
    
+
    
+
    Now what?
    
+
    Expo also has docs you can reference if you have questions specific to the tool. You can also ask for help at Expo forums.
    
+
    If you have a problem with Expo, before creating a new issue, please see if there's an existing issue about it:
    
+
+
    If you're curious to learn more about React Native, continue on to the Tutorial.
    
+
    Running your app on a simulator or virtual device
    
+
    Expo CLI makes it really easy to run your React Native app on a physical device without setting up a development environment. If you want to run your app on the iOS Simulator or an Android Virtual Device, please refer to the instructions for building projects with native code to learn how to install Xcode or set up your Android development environment.
    
+
    Once you've set these up, you can launch your app on an Android Virtual Device by running npm run android, or on the iOS Simulator by running npm run ios (macOS only).
    
+
    Caveats
    
+
    Because you don't build any native code when using Expo to create a project, it's not possible to include custom native modules beyond the React Native APIs and components that are available in the Expo client app.
    
+
    If you know that you'll eventually need to include your own native code, Expo is still a good way to get started. In that case you'll just need to "eject" eventually to create your own native builds. If you do eject, the "Building Projects with Native Code" instructions will be required to continue working on your project.
    
+
    Expo CLI configures your project to use the most recent React Native version that is supported by the Expo client app. The Expo client app usually gains support for a given React Native version about a week after the React Native version is released as stable. You can check this document to find out what versions are supported.
    
+
    If you're integrating React Native into an existing project, you'll want to skip Expo CLI and go directly to setting up the native build environment. Select "Building Projects with Native Code" above for instructions on configuring a native build environment for React Native.
    
+
    
+
    Follow these instructions if you need to build native code in your project. For example, if you are integrating React Native into an existing application, or if you "ejected" from Expo or Create React Native App, you'll need this section.
    
+
    The instructions are a bit different depending on your development operating system, and whether you want to start developing for iOS or Android. If you want to develop for both iOS and Android, that's fine - you just have to pick one to start with, since the setup is a bit different.
    
+
    
+  Development OS:
+  macOS
+  Windows
+  Linux
+  Target OS:
+  iOS
+  Android
+
    
+
    
+
    Unsupported
    
+
    A Mac is required to build projects with native code for iOS. You can follow the Quick Start to learn how to build your app using Expo instead.
    
+
    
+
    Installing dependencies
    
+
    You will need Node, Watchman, the React Native command line interface, and Xcode.
    
+
    While you can use any editor of your choice to develop your app, you will need to install Xcode in order to set up the necessary tooling to build your React Native app for iOS.
    
+
    
+
    Installing dependencies
    
+
    You will need Node, Watchman, the React Native command line interface, a JDK, and Android Studio.
    
+
    
+
    Installing dependencies
    
+
    You will need Node, the React Native command line interface, a JDK, and Android Studio.
    
+
    
+
    Installing dependencies
    
+
    You will need Node, the React Native command line interface, Python2, a JDK, and Android Studio.
    
+
    
+
    While you can use any editor of your choice to develop your app, you will need to install Android Studio in order to set up the necessary tooling to build your React Native app for Android.
    
+
    
+
    Node, Watchman
    
+
    We recommend installing Node and Watchman using Homebrew. Run the following commands in a Terminal after installing Homebrew:
    
+
    brew install node
+brew install watchman
+
    
+
    If you have already installed Node on your system, make sure it is Node 8.3 or newer.
    
+
    Watchman is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance.
    
+
    
+
    Node
    
+
    Follow the installation instructions for your Linux distribution to install Node 8.3 or newer.
    
+
    
+
    Node, Python2, JDK
    
+
    We recommend installing Node and Python2 via Chocolatey, a popular package manager for Windows.
    
+
    React Native also requires a recent version of the Java SE Development Kit (JDK), as well as Python 2. Both can be installed using Chocolatey.
    
+
    Open an Administrator Command Prompt (right click Command Prompt and select "Run as Administrator"), then run the following command:
    
+
    choco install -y nodejs.install python2 jdk8
+
    
+
    If you have already installed Node on your system, make sure it is Node 8.3 or newer. If you already have a JDK on your system, make sure it is version 8 or newer.
    
+
    
+
    You can find additional installation options on Node's Downloads page.
    
+
    
+
    
+
    The React Native CLI
    
+
    Node comes with npm, which lets you install the React Native command line interface.
    
+
    Run the following command in a Terminal:
    
+
    npm install -g react-native-cli
+
    
+
    
+
    If you get an error like Cannot find module 'npmlog', try installing npm directly: curl -0 -L https://npmjs.org/install.sh | sudo sh.
    
+
    
+
    
+
    The React Native CLI
    
+
    Node comes with npm, which lets you install the React Native command line interface.
    
+
    Run the following command in a Command Prompt or shell:
    
+
    npm install -g react-native-cli
+
    
+
    
+
    If you get an error like Cannot find module 'npmlog', try installing npm directly: curl -0 -L https://npmjs.org/install.sh | sudo sh.
    
+
    
+
    
+
    Xcode
    
+
    The easiest way to install Xcode is via the Mac App Store. Installing Xcode will also install the iOS Simulator and all the necessary tools to build your iOS app.
    
+
    If you have already installed Xcode on your system, make sure it is version 9.4 or newer.
    
+
    Command Line Tools
    
+
    You will also need to install the Xcode Command Line Tools. Open Xcode, then choose "Preferences..." from the Xcode menu. Go to the Locations panel and install the tools by selecting the most recent version in the Command Line Tools dropdown.
    
+
    Xcode Command Line Tools
    
+
    
+
    Java Development Kit
    
+
    React Native requires a recent version of the Java SE Development Kit (JDK). Download and install Oracle JDK 8 if needed. You can also use OpenJDK 8 as an alternative.
    
+
    
+
    Android development environment
    
+
    Setting up your development environment can be somewhat tedious if you're new to Android development. If you're already familiar with Android development, there are a few things you may need to configure. In either case, please make sure to carefully follow the next few steps.
    
+
    
+
    1. Install Android Studio
    
+
    Download and install Android Studio. Choose a "Custom" setup when prompted to select an installation type. Make sure the boxes next to all of the following are checked:
    
+
    
+
      
+
    • Android SDK
      • 
+
    • Android SDK Platform
      • 
+
    • Performance (Intel ® HAXM) (See here for AMD)
      • 
+
    • Android Virtual Device
      • 
+
    
+
    
+
      
+
    • Android SDK
      • 
+
    • Android SDK Platform
      • 
+
    • Android Virtual Device
      • 
+
    
+
    
+
    Then, click "Next" to install all of these components.
    
+
    
+
    If the checkboxes are grayed out, you will have a chance to install these components later on.
    
+
    
+
    Once setup has finalized and you're presented with the Welcome screen, proceed to the next step.
    
+
    2. Install the Android SDK
    
+
    Android Studio installs the latest Android SDK by default. Building a React Native app with native code, however, requires the Android 9 (Pie) SDK in particular. Additional Android SDKs can be installed through the SDK Manager in Android Studio.
    
+
    The SDK Manager can be accessed from the "Welcome to Android Studio" screen. Click on "Configure", then select "SDK Manager".
    
+
    
+
    Android Studio Welcome
    
+
    
+
    Android Studio Welcome
    
+
    
+
    
+
    The SDK Manager can also be found within the Android Studio "Preferences" dialog, under Appearance & Behavior → System Settings → Android SDK.
    
+
    
+
    Select the "SDK Platforms" tab from within the SDK Manager, then check the box next to "Show Package Details" in the bottom right corner. Look for and expand the Android 9 (Pie) entry, then make sure the following items are checked:
    
+
      
+
    • Android SDK Platform 28
      • 
+
    • Intel x86 Atom_64 System Image or Google APIs Intel x86 Atom System Image
      • 
+
    
+
    Next, select the "SDK Tools" tab and check the box next to "Show Package Details" here as well. Look for and expand the "Android SDK Build-Tools" entry, then make sure that 28.0.3 is selected.
    
+
    Finally, click "Apply" to download and install the Android SDK and related build tools.
    
+
    3. Configure the ANDROID_HOME environment variable
    
+
    The React Native tools require some environment variables to be set up in order to build apps with native code.
    
+
    
+
    Add the following lines to your $HOME/.bash_profile config file:
    
+
    
+
    export ANDROID_HOME=$HOME/Library/Android/sdk
+export PATH=$PATH:$ANDROID_HOME/emulator
+export PATH=$PATH:$ANDROID_HOME/tools
+export PATH=$PATH:$ANDROID_HOME/tools/bin
+export PATH=$PATH:$ANDROID_HOME/platform-tools
+
    
+
    
+
    export ANDROID_HOME=$HOME/Android/Sdk
+export PATH=$PATH:$ANDROID_HOME/emulator
+export PATH=$PATH:$ANDROID_HOME/tools
+export PATH=$PATH:$ANDROID_HOME/tools/bin
+export PATH=$PATH:$ANDROID_HOME/platform-tools
+
    
+
    
+
    
+
    .bash_profile is specific to bash. If you're using another shell, you will need to edit the appropriate shell-specific config file.
    
+
    
+
    Type source $HOME/.bash_profile to load the config into your current shell. Verify that ANDROID_HOME has been added to your path by running echo $PATH.
    
+
    
+
    Please make sure you use the correct Android SDK path. You can find the actual location of the SDK in the Android Studio "Preferences" dialog, under Appearance & Behavior → System Settings → Android SDK.
    
+
    
+
    
+
    Open the System pane under System and Security in the Windows Control Panel, then click on Change settings.... Open the Advanced tab and click on Environment Variables.... Click on New... to create a new ANDROID_HOME user variable that points to the path to your Android SDK:
    
+
    ANDROID_HOME Environment Variable
    
+
    The SDK is installed, by default, at the following location:
    
+
    c:\Users\YOUR_USERNAME\AppData\Local\Android\Sdk
+
    
+
    You can find the actual location of the SDK in the Android Studio "Preferences" dialog, under Appearance & Behavior → System Settings → Android SDK.
    
+
    Open a new Command Prompt window to ensure the new environment variable is loaded before proceeding to the next step.
    
+
    4. Add platform-tools to Path
    
+
    Open the System pane under System and Security in the Windows Control Panel, then click on Change settings.... Open the Advanced tab and click on Environment Variables.... Select the Path variable, then click Edit. Click New and add the path to platform-tools to the list.
    
+
    The default location for this folder is:
    
+
    c:\Users\YOUR_USERNAME\AppData\Local\Android\Sdk\platform-tools
+
    
+
    
+
    Watchman
    
+
    Follow the Watchman installation guide to compile and install Watchman from source.
    
+
    
+
    Watchman is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance and increased compatibility in certain edge cases (translation: you may be able to get by without installing this, but your mileage may vary; installing this now may save you from a headache later).
    
+
    
+
    
+
    Creating a new application
    
+
    Use the React Native command line interface to generate a new React Native project called "AwesomeProject":
    
+
    react-native init AwesomeProject
+
    
+
    This is not necessary if you are integrating React Native into an existing application, if you "ejected" from Expo (or Create React Native App), or if you're adding iOS support to an existing React Native project (see Platform Specific Code). You can also use a third-party CLI to init your React Native app, such as Ignite CLI.
    
+
    
+
    Creating a new application
    
+
    Use the React Native command line interface to generate a new React Native project called "AwesomeProject":
    
+
    react-native init AwesomeProject
+
    
+
    This is not necessary if you are integrating React Native into an existing application, if you "ejected" from Create React Native App, or if you're adding Android support to an existing React Native project (see Platform Specific Code). You can also use a third-party CLI to init your React Native app, such as Ignite CLI.
    
+
    
+
    Preparing the Android device
    
+
    You will need an Android device to run your React Native Android app. This can be either a physical Android device, or more commonly, you can use an Android Virtual Device which allows you to emulate an Android device on your computer.
    
+
    Either way, you will need to prepare the device to run Android apps for development.
    
+
    Using a physical device
    
+
    If you have a physical Android device, you can use it for development in place of an AVD by plugging it in to your computer using a USB cable and following the instructions here.
    
+
    Using a virtual device
    
+
    If you use Android Studio to open ./AwesomeProject/android, you can see the list of available Android Virtual Devices (AVDs) by opening the "AVD Manager" from within Android Studio. Look for an icon that looks like this:
    
+
    Android Studio AVD Manager
    
+
    If you have just installed Android Studio, you will likely need to create a new AVD. Select "Create Virtual Device...", then pick any Phone from the list and click "Next", then select the Pie API Level 28 image.
    
+
    
+
    
+
    We recommend configuring VM acceleration on your system to improve performance. Once you've followed those instructions, go back to the AVD Manager.
    
+
    
+
    
+
    
+
    If you don't have HAXM installed, click on "Install HAXM" or follow these instructions to set it up, then go back to the AVD Manager.
    
+
    
+
    
+
    
+
    If you don't have HAXM installed, follow these instructions to set it up, then go back to the AVD Manager.
    
+
    
+
    
+
    Click "Next" then "Finish" to create your AVD. At this point you should be able to click on the green triangle button next to your AVD to launch it, then proceed to the next step.
    
+
    
+
    Running your React Native application
    
+
    Run react-native run-ios inside your React Native project folder:
    
+
    cd AwesomeProject
+react-native run-ios
+
    
+
    You should see your new app running in the iOS Simulator shortly.
    
+
    AwesomeProject on iOS
    
+
    react-native run-ios is just one way to run your app. You can also run it directly from within Xcode or Nuclide.
    
+
    
+
    If you can't get this to work, see the Troubleshooting page.
    
+
    
+
    Running on a device
    
+
    The above command will automatically run your app on the iOS Simulator by default. If you want to run the app on an actual physical iOS device, please follow the instructions here.
    
+
    
+
    Running your React Native application
    
+
    Run react-native run-android inside your React Native project folder:
    
+
    cd AwesomeProject
+react-native run-android
+
    
+
    If everything is set up correctly, you should see your new app running in your Android emulator shortly.
    
+
    
+
    AwesomeProject on Android
    
+
    
+
    AwesomeProject on Android
    
+
    
+
    react-native run-android is just one way to run your app - you can also run it directly from within Android Studio or Nuclide.
    
+
    
+
    If you can't get this to work, see the Troubleshooting page.
    
+
    
+
    
+
    Modifying your app
    
+
    Now that you have successfully run the app, let's modify it.
    
+
    
+
      
+
    • Open App.js in your text editor of choice and edit some lines.
      • 
+
    • Hit ⌘R in your iOS Simulator to reload the app and see your changes!

    Getting Started
    
+
    This page will help you install and build your first React Native app. If you already have React Native installed, you can skip ahead to the Tutorial.
    
+
    
+  
      
+    
+    
+  
    
+
    
+
    
+
    Expo is the easiest way to start building a new React Native application. It allows you to start a project without installing or configuring any tools to build native code - no Xcode or Android Studio installation required (see Caveats).
    
+
    Assuming that you have Node 8+ installed, you can use npm to install the Expo CLI command line utility:
    
+
    npm install -g expo-cli
+
    
+
    Then run the following commands to create a new React Native project called "AwesomeProject":
    
+
    expo init AwesomeProject
+
+cd AwesomeProject
+npm start #you can also use: expo start
+
    
+
    This will start a development server for you.
    
+
    Running your React Native application
    
+
    Install the Expo client app on your iOS or Android phone and connect to the same wireless network as your computer. On Android, use the Expo app to scan the QR code from your terminal to open your project. On iOS, follow on-screen instructions to get a link.
    
+
    Modifying your app
    
+
    Now that you have successfully run the app, let's modify it. Open App.js in your text editor of choice and edit some lines. The application should reload automatically once you save your changes.
    
+
    That's it!
    
+
    Congratulations! You've successfully run and modified your first React Native app.
    
+
    
+
    Now what?
    
+
    Expo also has docs you can reference if you have questions specific to the tool. You can also ask for help at Expo forums.
    
+
    If you have a problem with Expo, before creating a new issue, please see if there's an existing issue about it:
    
+
+
    If you're curious to learn more about React Native, continue on to the Tutorial.
    
+
    Running your app on a simulator or virtual device
    
+
    Expo CLI makes it really easy to run your React Native app on a physical device without setting up a development environment. If you want to run your app on the iOS Simulator or an Android Virtual Device, please refer to the instructions for building projects with native code to learn how to install Xcode or set up your Android development environment.
    
+
    Once you've set these up, you can launch your app on an Android Virtual Device by running npm run android, or on the iOS Simulator by running npm run ios (macOS only).
    
+
    Caveats
    
+
    Because you don't build any native code when using Expo to create a project, it's not possible to include custom native modules beyond the React Native APIs and components that are available in the Expo client app.
    
+
    If you know that you'll eventually need to include your own native code, Expo is still a good way to get started. In that case you'll just need to "eject" eventually to create your own native builds. If you do eject, the "Building Projects with Native Code" instructions will be required to continue working on your project.
    
+
    Expo CLI configures your project to use the most recent React Native version that is supported by the Expo client app. The Expo client app usually gains support for a given React Native version about a week after the React Native version is released as stable. You can check this document to find out what versions are supported.
    
+
    If you're integrating React Native into an existing project, you'll want to skip Expo CLI and go directly to setting up the native build environment. Select "Building Projects with Native Code" above for instructions on configuring a native build environment for React Native.
    
+
    
+
    Follow these instructions if you need to build native code in your project. For example, if you are integrating React Native into an existing application, or if you "ejected" from Expo or Create React Native App, you'll need this section.
    
+
    The instructions are a bit different depending on your development operating system, and whether you want to start developing for iOS or Android. If you want to develop for both iOS and Android, that's fine - you just have to pick one to start with, since the setup is a bit different.
    
+
    
+  Development OS:
+  macOS
+  Windows
+  Linux
+  Target OS:
+  iOS
+  Android
+
    
+
    
+
    Unsupported
    
+
    A Mac is required to build projects with native code for iOS. You can follow the Quick Start to learn how to build your app using Expo instead.
    
+
    
+
    Installing dependencies
    
+
    You will need Node, Watchman, the React Native command line interface, and Xcode.
    
+
    While you can use any editor of your choice to develop your app, you will need to install Xcode in order to set up the necessary tooling to build your React Native app for iOS.
    
+
    
+
    Installing dependencies
    
+
    You will need Node, Watchman, the React Native command line interface, a JDK, and Android Studio.
    
+
    
+
    Installing dependencies
    
+
    You will need Node, the React Native command line interface, a JDK, and Android Studio.
    
+
    
+
    Installing dependencies
    
+
    You will need Node, the React Native command line interface, Python2, a JDK, and Android Studio.
    
+
    
+
    While you can use any editor of your choice to develop your app, you will need to install Android Studio in order to set up the necessary tooling to build your React Native app for Android.
    
+
    
+
    Node, Watchman
    
+
    We recommend installing Node and Watchman using Homebrew. Run the following commands in a Terminal after installing Homebrew:
    
+
    brew install node
+brew install watchman
+
    
+
    If you have already installed Node on your system, make sure it is Node 8.3 or newer.
    
+
    Watchman is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance.
    
+
    
+
    Node
    
+
    Follow the installation instructions for your Linux distribution to install Node 8.3 or newer.
    
+
    
+
    Node, Python2, JDK
    
+
    We recommend installing Node and Python2 via Chocolatey, a popular package manager for Windows.
    
+
    React Native also requires a recent version of the Java SE Development Kit (JDK), as well as Python 2. Both can be installed using Chocolatey.
    
+
    Open an Administrator Command Prompt (right click Command Prompt and select "Run as Administrator"), then run the following command:
    
+
    choco install -y nodejs.install python2 jdk8
+
    
+
    If you have already installed Node on your system, make sure it is Node 8.3 or newer. If you already have a JDK on your system, make sure it is version 8 or newer.
    
+
    
+
    You can find additional installation options on Node's Downloads page.
    
+
    
+
    
+
    The React Native CLI
    
+
    Node comes with npm, which lets you install the React Native command line interface.
    
+
    Run the following command in a Terminal:
    
+
    npm install -g react-native-cli
+
    
+
    
+
    If you get an error like Cannot find module 'npmlog', try installing npm directly: curl -0 -L https://npmjs.org/install.sh | sudo sh.
    
+
    
+
    
+
    The React Native CLI
    
+
    Node comes with npm, which lets you install the React Native command line interface.
    
+
    Run the following command in a Command Prompt or shell:
    
+
    npm install -g react-native-cli
+
    
+
    
+
    If you get an error like Cannot find module 'npmlog', try installing npm directly: curl -0 -L https://npmjs.org/install.sh | sudo sh.
    
+
    
+
    
+
    Xcode
    
+
    The easiest way to install Xcode is via the Mac App Store. Installing Xcode will also install the iOS Simulator and all the necessary tools to build your iOS app.
    
+
    If you have already installed Xcode on your system, make sure it is version 9.4 or newer.
    
+
    Command Line Tools
    
+
    You will also need to install the Xcode Command Line Tools. Open Xcode, then choose "Preferences..." from the Xcode menu. Go to the Locations panel and install the tools by selecting the most recent version in the Command Line Tools dropdown.
    
+
    Xcode Command Line Tools
    
+
    
+
    Java Development Kit
    
+
    React Native requires a recent version of the Java SE Development Kit (JDK). Download and install Oracle JDK 8 if needed. You can also use OpenJDK 8 as an alternative.
    
+
    
+
    Android development environment
    
+
    Setting up your development environment can be somewhat tedious if you're new to Android development. If you're already familiar with Android development, there are a few things you may need to configure. In either case, please make sure to carefully follow the next few steps.
    
+
    
+
    1. Install Android Studio
    
+
    Download and install Android Studio. Choose a "Custom" setup when prompted to select an installation type. Make sure the boxes next to all of the following are checked:
    
+
    
+
      
+
    • Android SDK
      • 
+
    • Android SDK Platform
      • 
+
    • Performance (Intel ® HAXM) (See here for AMD)
      • 
+
    • Android Virtual Device
      • 
+
    
+
    
+
      
+
    • Android SDK
      • 
+
    • Android SDK Platform
      • 
+
    • Android Virtual Device
      • 
+
    
+
    
+
    Then, click "Next" to install all of these components.
    
+
    
+
    If the checkboxes are grayed out, you will have a chance to install these components later on.
    
+
    
+
    Once setup has finalized and you're presented with the Welcome screen, proceed to the next step.
    
+
    2. Install the Android SDK
    
+
    Android Studio installs the latest Android SDK by default. Building a React Native app with native code, however, requires the Android 9 (Pie) SDK in particular. Additional Android SDKs can be installed through the SDK Manager in Android Studio.
    
+
    The SDK Manager can be accessed from the "Welcome to Android Studio" screen. Click on "Configure", then select "SDK Manager".
    
+
    
+
    Android Studio Welcome
    
+
    
+
    Android Studio Welcome
    
+
    
+
    
+
    The SDK Manager can also be found within the Android Studio "Preferences" dialog, under Appearance & Behavior → System Settings → Android SDK.
    
+
    
+
    Select the "SDK Platforms" tab from within the SDK Manager, then check the box next to "Show Package Details" in the bottom right corner. Look for and expand the Android 9 (Pie) entry, then make sure the following items are checked:
    
+
      
+
    • Android SDK Platform 28
      • 
+
    • Intel x86 Atom_64 System Image or Google APIs Intel x86 Atom System Image
      • 
+
    
+
    Next, select the "SDK Tools" tab and check the box next to "Show Package Details" here as well. Look for and expand the "Android SDK Build-Tools" entry, then make sure that 28.0.3 is selected.
    
+
    Finally, click "Apply" to download and install the Android SDK and related build tools.
    
+
    3. Configure the ANDROID_HOME environment variable
    
+
    The React Native tools require some environment variables to be set up in order to build apps with native code.
    
+
    
+
    Add the following lines to your $HOME/.bash_profile config file:
    
+
    
+
    export ANDROID_HOME=$HOME/Library/Android/sdk
+export PATH=$PATH:$ANDROID_HOME/emulator
+export PATH=$PATH:$ANDROID_HOME/tools
+export PATH=$PATH:$ANDROID_HOME/tools/bin
+export PATH=$PATH:$ANDROID_HOME/platform-tools
+
    
+
    
+
    export ANDROID_HOME=$HOME/Android/Sdk
+export PATH=$PATH:$ANDROID_HOME/emulator
+export PATH=$PATH:$ANDROID_HOME/tools
+export PATH=$PATH:$ANDROID_HOME/tools/bin
+export PATH=$PATH:$ANDROID_HOME/platform-tools
+
    
+
    
+
    
+
    .bash_profile is specific to bash. If you're using another shell, you will need to edit the appropriate shell-specific config file.
    
+
    
+
    Type source $HOME/.bash_profile to load the config into your current shell. Verify that ANDROID_HOME has been added to your path by running echo $PATH.
    
+
    
+
    Please make sure you use the correct Android SDK path. You can find the actual location of the SDK in the Android Studio "Preferences" dialog, under Appearance & Behavior → System Settings → Android SDK.
    
+
    
+
    
+
    Open the System pane under System and Security in the Windows Control Panel, then click on Change settings.... Open the Advanced tab and click on Environment Variables.... Click on New... to create a new ANDROID_HOME user variable that points to the path to your Android SDK:
    
+
    ANDROID_HOME Environment Variable
    
+
    The SDK is installed, by default, at the following location:
    
+
    c:\Users\YOUR_USERNAME\AppData\Local\Android\Sdk
+
    
+
    You can find the actual location of the SDK in the Android Studio "Preferences" dialog, under Appearance & Behavior → System Settings → Android SDK.
    
+
    Open a new Command Prompt window to ensure the new environment variable is loaded before proceeding to the next step.
    
+
    4. Add platform-tools to Path
    
+
    Open the System pane under System and Security in the Windows Control Panel, then click on Change settings.... Open the Advanced tab and click on Environment Variables.... Select the Path variable, then click Edit. Click New and add the path to platform-tools to the list.
    
+
    The default location for this folder is:
    
+
    c:\Users\YOUR_USERNAME\AppData\Local\Android\Sdk\platform-tools
+
    
+
    
+
    Watchman
    
+
    Follow the Watchman installation guide to compile and install Watchman from source.
    
+
    
+
    Watchman is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance and increased compatibility in certain edge cases (translation: you may be able to get by without installing this, but your mileage may vary; installing this now may save you from a headache later).
    
+
    
+
    
+
    Creating a new application
    
+
    Use the React Native command line interface to generate a new React Native project called "AwesomeProject":
    
+
    react-native init AwesomeProject
+
    
+
    This is not necessary if you are integrating React Native into an existing application, if you "ejected" from Expo (or Create React Native App), or if you're adding iOS support to an existing React Native project (see Platform Specific Code). You can also use a third-party CLI to init your React Native app, such as Ignite CLI.
    
+
    
+
    Creating a new application
    
+
    Use the React Native command line interface to generate a new React Native project called "AwesomeProject":
    
+
    react-native init AwesomeProject
+
    
+
    This is not necessary if you are integrating React Native into an existing application, if you "ejected" from Create React Native App, or if you're adding Android support to an existing React Native project (see Platform Specific Code). You can also use a third-party CLI to init your React Native app, such as Ignite CLI.
    
+
    
+
    Preparing the Android device
    
+
    You will need an Android device to run your React Native Android app. This can be either a physical Android device, or more commonly, you can use an Android Virtual Device which allows you to emulate an Android device on your computer.
    
+
    Either way, you will need to prepare the device to run Android apps for development.
    
+
    Using a physical device
    
+
    If you have a physical Android device, you can use it for development in place of an AVD by plugging it in to your computer using a USB cable and following the instructions here.
    
+
    Using a virtual device
    
+
    If you use Android Studio to open ./AwesomeProject/android, you can see the list of available Android Virtual Devices (AVDs) by opening the "AVD Manager" from within Android Studio. Look for an icon that looks like this:
    
+
    Android Studio AVD Manager
    
+
    If you have just installed Android Studio, you will likely need to create a new AVD. Select "Create Virtual Device...", then pick any Phone from the list and click "Next", then select the Pie API Level 28 image.
    
+
    
+
    
+
    We recommend configuring VM acceleration on your system to improve performance. Once you've followed those instructions, go back to the AVD Manager.
    
+
    
+
    
+
    
+
    If you don't have HAXM installed, click on "Install HAXM" or follow these instructions to set it up, then go back to the AVD Manager.
    
+
    
+
    
+
    
+
    If you don't have HAXM installed, follow these instructions to set it up, then go back to the AVD Manager.
    
+
    
+
    
+
    Click "Next" then "Finish" to create your AVD. At this point you should be able to click on the green triangle button next to your AVD to launch it, then proceed to the next step.
    
+
    
+
    Running your React Native application
    
+
    Run react-native run-ios inside your React Native project folder:
    
+
    cd AwesomeProject
+react-native run-ios
+
    
+
    You should see your new app running in the iOS Simulator shortly.
    
+
    AwesomeProject on iOS
    
+
    react-native run-ios is just one way to run your app. You can also run it directly from within Xcode or Nuclide.
    
+
    
+
    If you can't get this to work, see the Troubleshooting page.
    
+
    
+
    Running on a device
    
+
    The above command will automatically run your app on the iOS Simulator by default. If you want to run the app on an actual physical iOS device, please follow the instructions here.
    
+
    
+
    Running your React Native application
    
+
    Run react-native run-android inside your React Native project folder:
    
+
    cd AwesomeProject
+react-native run-android
+
    
+
    If everything is set up correctly, you should see your new app running in your Android emulator shortly.
    
+
    
+
    AwesomeProject on Android
    
+

+
    
+
    
+
    Modifying your app
    
+
    Now that you have successfully run the app, let's modify it.
    
+
    
+
      
+
    • Open App.js in your text editor of choice and edit some lines.
      • 
+
    • Hit ⌘R in your iOS Simulator to reload the app and see your changes!

    Handling Text Input
    TextInput is a basic component that allows the user to enter text. It has an onChangeText prop that takes a function to be called every time the text changed, and an onSubmitEditing prop that takes a function to be called when the text is submitted.
    
+
    For example, let's say that as the user types, you're translating their words into a different language. In this new language, every single word is written the same way: 🍕. So the sentence "Hello there Bob" would be translated as "🍕🍕🍕".
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Text, TextInput, View } from 'react-native';
+
+export default class PizzaTranslator extends Component {
+  constructor(props) {
+    super(props);
+    this.state = {text: ''};
+  }
+
+  render() {
+    return (
+      <View style={{padding: 10}}>
+        <TextInput
+          style={{height: 40}}
+          placeholder="Type here to translate!"
+          onChangeText={(text) => this.setState({text})}
+        />
+        <Text style={{padding: 10, fontSize: 42}}>
+          {this.state.text.split(' ').map((word) => word && '🍕').join(' ')}
+        </Text>
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => PizzaTranslator);
+
    
+
+
    In this example, we store text in the state, because it changes over time.
    
+
    There are a lot more things you might want to do with a text input. For example, you could validate the text inside while the user types. For more detailed examples, see the React docs on controlled components, or the reference docs for TextInput.
    
+
    Text input is one of the ways the user interacts with the app. Next, let's look at another type of input and learn how to handle touches.

+
    
+
+
    In this example, we store text in the state, because it changes over time.
    
+
    There are a lot more things you might want to do with a text input. For example, you could validate the text inside while the user types. For more detailed examples, see the React docs on controlled components, or the reference docs for TextInput.
    
+
    Text input is one of the ways the user interacts with the app. Next, let's look at another type of input and learn how to handle touches.

+Handling Touches · React Native
    0.58
    Edit
    Handling Touches
    Users interact with mobile apps mainly through touch. They can use a combination of gestures, such as tapping on a button, scrolling a list, or zooming on a map. React Native provides components to handle all sorts of common gestures, as well as a comprehensive gesture responder system to allow for more advanced gesture recognition, but the one component you will most likely be interested in is the basic Button.
    
+
    Displaying a basic button
    
+
    Button provides a basic button component that is rendered nicely on all platforms. The minimal example to display a button looks like this:
    
+
    <Button
+  onPress={() => {
+    Alert.alert('You tapped the button!');
+  }}
+  title="Press Me"
+/>
+
    
+
    This will render a blue label on iOS, and a blue rounded rectangle with white text on Android. Pressing the button will call the "onPress" function, which in this case displays an alert popup. If you like, you can specify a "color" prop to change the color of your button.
    
+
    
+
    Go ahead and play around with the Button component using the example below. You can select which platform your app is previewed in by clicking on the toggle in the bottom right, then click on "Tap to Play" to preview the app.
    
+
    Touchables
    
+
    If the basic button doesn't look right for your app, you can build your own button using any of the "Touchable" components provided by React Native. The "Touchable" components provide the capability to capture tapping gestures, and can display feedback when a gesture is recognized. These components do not provide any default styling, however, so you will need to do a bit of work to get them looking nicely in your app.
    
+
    Which "Touchable" component you use will depend on what kind of feedback you want to provide:
    
+
      
+
    • Generally, you can use TouchableHighlight anywhere you would use a button or link on web. The view's background will be darkened when the user presses down on the button.
      • 
+
    • You may consider using TouchableNativeFeedback on Android to display ink surface reaction ripples that respond to the user's touch.
      • 
+
    • TouchableOpacity can be used to provide feedback by reducing the opacity of the button, allowing the background to be seen through while the user is pressing down.
      • 
+
    • If you need to handle a tap gesture but you don't want any feedback to be displayed, use TouchableWithoutFeedback.
      • 
+
    
+
    In some cases, you may want to detect when a user presses and holds a view for a set amount of time. These long presses can be handled by passing a function to the onLongPress props of any of the "Touchable" components.
    
+
    Let's see all of these in action:
    
+
    Scrolling lists, swiping pages, and pinch-to-zoom
    
+
    Another gesture commonly used in mobile apps is the swipe or pan. This gesture allows the user to scroll through a list of items, or swipe through pages of content. In order to handle these and other gestures, we'll learn how to use a ScrollView next.

+Headless JS · React Native
    0.58
    Edit
    Headless JS
    Headless JS is a way to run tasks in JavaScript while your app is in the background. It can be used, for example, to sync fresh data, handle push notifications, or play music.
    
+
    The JS API
    
+
    A task is a simple async function that you register on AppRegistry, similar to registering React applications:
    
+
    AppRegistry.registerHeadlessTask('SomeTaskName', () => require('SomeTaskName'));
+
    
+
    Then, in SomeTaskName.js:
    
+
    module.exports = async (taskData) => {
+  // do stuff
+};
+
    
+
    You can do anything in your task such as network requests, timers and so on, as long as it doesn't touch UI. Once your task completes (i.e. the promise is resolved), React Native will go into "paused" mode (unless there are other tasks running, or there is a foreground app).
    
+
    The Java API
    
+
    Yes, this does still require some native code, but it's pretty thin. You need to extend HeadlessJsTaskService and override getTaskConfig, e.g.:
    
+
    public class MyTaskService extends HeadlessJsTaskService {
+
+  @Override
+  protected @Nullable HeadlessJsTaskConfig getTaskConfig(Intent intent) {
+    Bundle extras = intent.getExtras();
+    if (extras != null) {
+      return new HeadlessJsTaskConfig(
+          "SomeTaskName",
+          Arguments.fromBundle(extras),
+          5000, // timeout for the task
+          false // optional: defines whether or not  the task is allowed in foreground. Default is false
+        );
+    }
+    return null;
+  }
+}
+
    
+
    Then add the service to your AndroidManifest.xml file:
    
+
    <service android:name="com.example.MyTaskService" />
+
    
+
    Now, whenever you start your service, e.g. as a periodic task or in response to some system event / broadcast, JS will spin up, run your task, then spin down.
    
+
    Example:
    
+
    Intent service = new Intent(getApplicationContext(), MyTaskService.class);
+Bundle bundle = new Bundle();
+
+bundle.putString("foo", "bar");
+service.putExtras(bundle);
+
+getApplicationContext().startService(service);
+
    
+
    Caveats
    
+
      
+
    • By default, your app will crash if you try to run a task while the app is in the foreground. This is to prevent developers from shooting themselves in the foot by doing a lot of work in a task and slowing the UI. You can pass a fourth boolean argument to control this behaviour.
      • 
+
    • If you start your service from a BroadcastReceiver, make sure to call HeadlessJsTaskService.acquireWakeLockNow() before returning from onReceive().
      • 
+
    
+
    Example Usage
    
+
    Service can be started from Java API. First you need to decide when the service should be started and implement your solution accordingly. Here is a simple example that reacts to network connection change.
    
+
    Following lines shows part of Android manifest file for registering broadcast receiver.
    
+
    <receiver android:name=".NetworkChangeReceiver" >
+  <intent-filter>
+    <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
+  </intent-filter>
+</receiver>
+
    
+
    Broadcast receiver then handles intent that was broadcasted in onReceive function. This is a great place to check whether your app is on foreground or not. If app is not on foreground we can prepare our intent to be started, with no information or additional information bundled using putExtra (keep in mind bundle can handle only parcelable values). In the end service is started and wakelock is acquired.
    
+
    public class NetworkChangeReceiver extends BroadcastReceiver {
+
+    @Override
+    public void onReceive(final Context context, final Intent intent) {
+        /**
+          This part will be called everytime network connection is changed
+          e.g. Connected -> Not Connected
+        **/
+        if (!isAppOnForeground((context))) {
+            /**
+              We will start our service and send extra info about
+              network connections
+            **/
+            boolean hasInternet = isNetworkAvailable(context);
+            Intent serviceIntent = new Intent(context, MyTaskService.class);
+            serviceIntent.putExtra("hasInternet", hasInternet);
+            context.startService(serviceIntent);
+            HeadlessJsTaskService.acquireWakeLockNow(context);
+        }
+    }
+
+    private boolean isAppOnForeground(Context context) {
+        /**
+          We need to check if app is in foreground otherwise the app will crash.
+         http://stackoverflow.com/questions/8489993/check-android-application-is-in-foreground-or-not
+        **/
+        ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
+        List<ActivityManager.RunningAppProcessInfo> appProcesses =
+        activityManager.getRunningAppProcesses();
+        if (appProcesses == null) {
+            return false;
+        }
+        final String packageName = context.getPackageName();
+        for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
+            if (appProcess.importance ==
+            ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND &&
+             appProcess.processName.equals(packageName)) {
+                return true;
+            }
+        }
+        return false;
+    }
+
+    public static boolean isNetworkAvailable(Context context) {
+        ConnectivityManager cm = (ConnectivityManager)
+        context.getSystemService(Context.CONNECTIVITY_SERVICE);
+        NetworkInfo netInfo = cm.getActiveNetworkInfo();
+        return (netInfo != null && netInfo.isConnected());
+    }
+

+}

    Height and Width
    A component's height and width determine its size on the screen.
    
+
    Fixed Dimensions
    
+
    The simplest way to set the dimensions of a component is by adding a fixed width and height to style. All dimensions in React Native are unitless, and represent density-independent pixels.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View } from 'react-native';
+
+export default class FixedDimensionsBasics extends Component {
+  render() {
+    return (
+      <View>
+        <View style={{width: 50, height: 50, backgroundColor: 'powderblue'}} />
+        <View style={{width: 100, height: 100, backgroundColor: 'skyblue'}} />
+        <View style={{width: 150, height: 150, backgroundColor: 'steelblue'}} />
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => FixedDimensionsBasics);
+
    
+
+
    Setting dimensions this way is common for components that should always render at exactly the same size, regardless of screen dimensions.
    
+
    Flex Dimensions
    
+
    Use flex in a component's style to have the component expand and shrink dynamically based on available space. Normally you will use flex: 1, which tells a component to fill all available space, shared evenly amongst other components with the same parent. The larger the flex given, the higher the ratio of space a component will take compared to its siblings.
    
+
    
+
    A component can only expand to fill available space if its parent has dimensions greater than 0. If a parent does not have either a fixed width and height or flex, the parent will have dimensions of 0 and the flex children will not be visible.
    
+
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View } from 'react-native';
+
+export default class FlexDimensionsBasics extends Component {
+  render() {
+    return (
+      // Try removing the `flex: 1` on the parent View.
+      // The parent will not have dimensions, so the children can't expand.
+      // What if you add `height: 300` instead of `flex: 1`?
+      <View style={{flex: 1}}>
+        <View style={{flex: 1, backgroundColor: 'powderblue'}} />
+        <View style={{flex: 2, backgroundColor: 'skyblue'}} />
+        <View style={{flex: 3, backgroundColor: 'steelblue'}} />
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => FlexDimensionsBasics);
+
    
+
+
    After you can control a component's size, the next step is to learn how to lay it out on the screen.

    Height and Width
    A component's height and width determine its size on the screen.
    
+
    Fixed Dimensions
    
+
    The simplest way to set the dimensions of a component is by adding a fixed width and height to style. All dimensions in React Native are unitless, and represent density-independent pixels.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View } from 'react-native';
+
+export default class FixedDimensionsBasics extends Component {
+  render() {
+    return (
+      <View>
+        <View style={{width: 50, height: 50, backgroundColor: 'powderblue'}} />
+        <View style={{width: 100, height: 100, backgroundColor: 'skyblue'}} />
+        <View style={{width: 150, height: 150, backgroundColor: 'steelblue'}} />
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => FixedDimensionsBasics);
+
    
+
+
    Setting dimensions this way is common for components that should always render at exactly the same size, regardless of screen dimensions.
    
+
    Flex Dimensions
    
+
    Use flex in a component's style to have the component expand and shrink dynamically based on available space. Normally you will use flex: 1, which tells a component to fill all available space, shared evenly amongst other components with the same parent. The larger the flex given, the higher the ratio of space a component will take compared to its siblings.
    
+
    
+
    A component can only expand to fill available space if its parent has dimensions greater than 0. If a parent does not have either a fixed width and height or flex, the parent will have dimensions of 0 and the flex children will not be visible.
    
+
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View } from 'react-native';
+
+export default class FlexDimensionsBasics extends Component {
+  render() {
+    return (
+      // Try removing the `flex: 1` on the parent View.
+      // The parent will not have dimensions, so the children can't expand.
+      // What if you add `height: 300` instead of `flex: 1`?
+      <View style={{flex: 1}}>
+        <View style={{flex: 1, backgroundColor: 'powderblue'}} />
+        <View style={{flex: 2, backgroundColor: 'skyblue'}} />
+        <View style={{flex: 3, backgroundColor: 'steelblue'}} />
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => FlexDimensionsBasics);
+
    
+
+
    After you can control a component's size, the next step is to learn how to lay it out on the screen.

    Image
    A React component for displaying different types of images, including network images, static resources, temporary local images, and images from local disk, such as the camera roll.
    
+
    This example shows fetching and displaying an image from local storage as well as one from network and even from data provided in the 'data:' uri scheme.
    
+
    
+
    Note that for network and data images, you will need to manually specify the dimensions of your image!
    
+
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View, Image } from 'react-native';
+
+export default class DisplayAnImage extends Component {
+  render() {
+    return (
+      <View>
+        <Image
+          source={require('/react-native/img/favicon.png')}
+        />
+        <Image
+          style={{width: 50, height: 50}}
+          source={{uri: 'https://facebook.github.io/react-native/docs/assets/favicon.png'}}
+        />
+        <Image
+          style={{width: 66, height: 58}}
+          source={{uri: 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg=='}}
+        />
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('DisplayAnImage', () => DisplayAnImage);
+
    
+
+
    You can also add style to an image:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View, Image, StyleSheet } from 'react-native';
+
+const styles = StyleSheet.create({
+  stretch: {
+    width: 50,
+    height: 200
+  }
+});
+
+export default class DisplayAnImageWithStyle extends Component {
+  render() {
+    return (
+      <View>
+        <Image
+          style={styles.stretch}
+          source={require('/react-native/img/favicon.png')}
+        />
+      </View>
+    );
+  }
+}
+
+// skip these lines if using Create React Native App
+AppRegistry.registerComponent(
+  'DisplayAnImageWithStyle',
+  () => DisplayAnImageWithStyle
+);

+
+
    GIF and WebP support on Android
    
+
    When building your own native code, GIF and WebP are not supported by default on Android.
    
+
    You will need to add some optional modules in android/app/build.gradle, depending on the needs of your app.
    
+
    dependencies {
+  // If your app supports Android versions before Ice Cream Sandwich (API level 14)
+  compile 'com.facebook.fresco:animated-base-support:1.10.0'
+
+  // For animated GIF support
+  compile 'com.facebook.fresco:animated-gif:1.10.0'
+
+  // For WebP support, including animated WebP
+  compile 'com.facebook.fresco:animated-webp:1.10.0'
+  compile 'com.facebook.fresco:webpsupport:1.10.0'
+
+  // For WebP support, without animations
+  compile 'com.facebook.fresco:webpsupport:1.10.0'

+
      
+
    • cover: Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or larger than the corresponding dimension of the view (minus padding).
      • 
+
    • contain: Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or less than the corresponding dimension of the view (minus padding).
      • 
+
    • stretch: Scale width and height independently, This may change the aspect ratio of the src.
      • 
+
    • repeat: Repeat the image to cover the frame of the view. The image will keep its size and aspect ratio, unless it is larger than the view, in which case it will be scaled down uniformly so that it is contained in the view.
      • 
+
    • center: Center the image in the view along both dimensions. If the image is larger than the view, scale it down uniformly so that it is contained in the view.

+
    resizeMethod
    
+
    The mechanism that should be used to resize the image when the image's dimensions differ from the image view's dimensions. Defaults to auto.
    
+
      
+
    • auto: Use heuristics to pick between resize and scale.
      • 
+
    • resize: A software operation which changes the encoded image in memory before it gets decoded. This should be used instead of scale when the image is much larger than the view.
      • 
+
    • scale: The image gets drawn downscaled or upscaled. Compared to resize, scale is faster (usually hardware accelerated) and produces higher quality images. This should be used if the image is smaller than the view. It should also be used if the image is slightly bigger than the view.
      • 
+
    
+
    More details about resize and scale can be found at http://frescolib.org/docs/resizing.html.
    
+
+
+
+

+
+
+
+
+
+
+
    TypeRequiredPlatform
    nodeNoiOS

+
    TypeRequiredPlatform
    boolNoiOS
    
+
    
+
    capInsets
    
+
    When the image is resized, the corners of the size specified by capInsets will stay a fixed size, but the center content and borders of the image will be stretched. This is useful for creating resizable rounded buttons, shadows, and other resizable assets. More info in the official Apple documentation.

    Image
    A React component for displaying different types of images, including network images, static resources, temporary local images, and images from local disk, such as the camera roll.
    
+
    This example shows fetching and displaying an image from local storage as well as one from network and even from data provided in the 'data:' uri scheme.
    
+
    
+
    Note that for network and data images, you will need to manually specify the dimensions of your image!
    
+
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View, Image } from 'react-native';
+
+export default class DisplayAnImage extends Component {
+  render() {
+    return (
+      <View>
+        <Image
+          source={require('/react-native/img/favicon.png')}
+        />
+        <Image
+          style={{width: 50, height: 50}}
+          source={{uri: 'https://facebook.github.io/react-native/docs/assets/favicon.png'}}
+        />
+        <Image
+          style={{width: 66, height: 58}}
+          source={{uri: 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg=='}}
+        />
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('DisplayAnImage', () => DisplayAnImage);
+
    
+
+
    You can also add style to an image:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View, Image, StyleSheet } from 'react-native';
+
+const styles = StyleSheet.create({
+  stretch: {
+    width: 50,
+    height: 200
+  }
+});
+
+export default class DisplayAnImageWithStyle extends Component {
+  render() {
+    return (
+      <View>
+        <Image
+          style={styles.stretch}
+          source={require('/react-native/img/favicon.png')}
+        />
+      </View>
+    );
+  }
+}
+
+// skip these lines if using Create React Native App
+AppRegistry.registerComponent(
+  'DisplayAnImageWithStyle',
+  () => DisplayAnImageWithStyle
+);
+
    
+
+
    GIF and WebP support on Android
    
+
    When building your own native code, GIF and WebP are not supported by default on Android.
    
+
    You will need to add some optional modules in android/app/build.gradle, depending on the needs of your app.
    
+
    dependencies {
+  // If your app supports Android versions before Ice Cream Sandwich (API level 14)
+  compile 'com.facebook.fresco:animated-base-support:1.10.0'
+
+  // For animated GIF support
+  compile 'com.facebook.fresco:animated-gif:1.10.0'
+
+  // For WebP support, including animated WebP
+  compile 'com.facebook.fresco:animated-webp:1.10.0'
+  compile 'com.facebook.fresco:webpsupport:1.10.0'
+
+  // For WebP support, without animations
+  compile 'com.facebook.fresco:webpsupport:1.10.0'
+}

+
      Changes the color of all the non-transparent pixels to the tintColor.
      • 
+
    • overlayColor: string (Android)
      
+
      When the image has rounded corners, specifying an overlayColor will cause the remaining space in the corners to be filled with a solid color. This is useful in cases which are not supported by the Android implementation of rounded corners:
      
+
        
+
      • Certain resize modes, such as 'contain'
        • 
+
      • Animated GIFs
        • 
+
      
+
      A typical way to use this prop is with images displayed on a solid background and setting the overlayColor to the same color as the background.

    Determines how to resize the image when the frame doesn't match the raw image dimensions.
    
+
      
+
    • cover: Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or larger than the corresponding dimension of the view (minus padding).
      • 
+
    • contain: Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or less than the corresponding dimension of the view (minus padding).
      • 
+
    • stretch: Scale width and height independently, This may change the aspect ratio of the src.
      • 
+
    • repeat: Repeat the image to cover the frame of the view. The image will keep its size and aspect ratio, unless it is larger than the view, in which case it will be scaled down uniformly so that it is contained in the view.
      • 
+
    • center: Center the image in the view along both dimensions. If the image is larger than the view, scale it down uniformly so that it is contained in the view.
      •

    source
    
+
    The image source (either a remote URL or a local file resource).
    
+
    This prop can also contain several remote URLs, specified together with their width and height and potentially with scale/other URI arguments. The native side will then choose the best uri to display based on the measured size of the image container. A cache property can be added to control how networked request interacts with the local cache.
    
+
    The currently supported formats are png, jpg, jpeg, bmp, gif, webp (Android only), psd (iOS only).

    resizeMethod
    
+
    The mechanism that should be used to resize the image when the image's dimensions differ from the image view's dimensions. Defaults to auto.
    
+
      
+
    • auto: Use heuristics to pick between resize and scale.
      • 
+
    • resize: A software operation which changes the encoded image in memory before it gets decoded. This should be used instead of scale when the image is much larger than the view.
      • 
+
    • scale: The image gets drawn downscaled or upscaled. Compared to resize, scale is faster (usually hardware accelerated) and produces higher quality images. This should be used if the image is smaller than the view. It should also be used if the image is slightly bigger than the view.
      • 
+
    
+
    More details about resize and scale can be found at http://frescolib.org/docs/resizing.html.

    capInsets
    
+
    When the image is resized, the corners of the size specified by capInsets will stay a fixed size, but the center content and borders of the image will be stretched. This is useful for creating resizable rounded buttons, shadows, and other resizable assets. More info in the official Apple documentation.

    ImageBackground
    A common feature request from developers familiar with the web is background-image. To handle this use case, you can use the <ImageBackground> component, which has the same props as <Image>, and add whatever children to it you would like to layer on top of it.
    
+
    You might not want to use <ImageBackground> in some cases, since the implementation is very simple. Refer to <ImageBackground>'s source code for more insight, and create your own custom component when needed.
    
+
    Note that you must specify some width and height style attributes.
    
+
    Example
    
+
    return (
+  <ImageBackground source={...} style={{width: '100%', height: '100%'}}>

    Images
    Static Image Resources
    
+
    React Native provides a unified way of managing images and other media assets in your iOS and Android apps. To add a static image to your app, place it somewhere in your source code tree and reference it like this:
    
+
    <Image source={require('./my-icon.png')} />
+
    
+
    The image name is resolved the same way JS modules are resolved. In the example above, the packager will look for my-icon.png in the same folder as the component that requires it. Also, if you have my-icon.ios.png and my-icon.android.png, the packager will pick the correct file for the platform.
    
+
    You can also use the @2x and @3x suffixes to provide images for different screen densities. If you have the following file structure:
    
+
    .
+├── button.js
+└── img
+    ├── check.png
+    ├── check@2x.png
+    └── check@3x.png
+
    
+
    ...and button.js code contains:
    
+
    <Image source={require('./img/check.png')} />
+
    
+
    ...the packager will bundle and serve the image corresponding to device's screen density. For example, check@2x.png, will be used on an iPhone 7, whilecheck@3x.png will be used on an iPhone 7 Plus or a Nexus 5. If there is no image matching the screen density, the closest best option will be selected.
    
+
    On Windows, you might need to restart the packager if you add new images to your project.
    
+
    Here are some benefits that you get:
    
+
      
+
    1. Same system on iOS and Android.
      2. 
+
    2. Images live in the same folder as your JavaScript code. Components are self-contained.
      3. 
+
    3. No global namespace, i.e. you don't have to worry about name collisions.
      4. 
+
    4. Only the images that are actually used will be packaged into your app.
      5. 
+
    5. Adding and changing images doesn't require app recompilation, just refresh the simulator as you normally do.
      6. 
+
    6. The packager knows the image dimensions, no need to duplicate it in the code.
      7. 
+
    7. Images can be distributed via npm packages.
      8. 
+
    
+
    In order for this to work, the image name in require has to be known statically.
    
+
    // GOOD
+<Image source={require('./my-icon.png')} />;
+
+// BAD
+var icon = this.props.active ? 'my-icon-active' : 'my-icon-inactive';
+<Image source={require('./' + icon + '.png')} />;
+
+// GOOD
+var icon = this.props.active
+  ? require('./my-icon-active.png')
+  : require('./my-icon-inactive.png');
+<Image source={icon} />;
+
    
+
    Note that image sources required this way include size (width, height) info for the Image. If you need to scale the image dynamically (i.e. via flex), you may need to manually set { width: undefined, height: undefined } on the style attribute.
    
+
    Static Non-Image Resources
    
+
    The require syntax described above can be used to statically include audio, video or document files in your project as well. Most common file types are supported including .mp3, .wav, .mp4, .mov, .html and .pdf. See packager defaults for the full list.
    
+
    You can add support for other types by creating a packager config file (see the packager config file for the full list of configuration options).
    
+
    A caveat is that videos must use absolute positioning instead of flexGrow, since size info is not currently passed for non-image assets. This limitation doesn't occur for videos that are linked directly into Xcode or the Assets folder for Android.
    
+
    Images From Hybrid App's Resources
    
+
    If you are building a hybrid app (some UIs in React Native, some UIs in platform code) you can still use images that are already bundled into the app.
    
+
    For images included via Xcode asset catalogs or in the Android drawable folder, use the image name without the extension:
    
+
    <Image source={{uri: 'app_icon'}} style={{width: 40, height: 40}} />
+
    
+
    For images in the Android assets folder, use the asset:/ scheme:
    
+
    <Image source={{uri: 'asset:/app_icon.png'}} style={{width: 40, height: 40}} />
+
    
+
    These approaches provide no safety checks. It's up to you to guarantee that those images are available in the application. Also you have to specify image dimensions manually.
    
+
    Network Images
    
+
    Many of the images you will display in your app will not be available at compile time, or you will want to load some dynamically to keep the binary size down. Unlike with static resources, you will need to manually specify the dimensions of your image. It's highly recommended that you use https as well in order to satisfy App Transport Security requirements on iOS.
    
+
    // GOOD
+<Image source={{uri: 'https://facebook.github.io/react/logo-og.png'}}
+       style={{width: 400, height: 400}} />
+
+// BAD
+<Image source={{uri: 'https://facebook.github.io/react/logo-og.png'}} />
+
    
+
    Network Requests for Images
    
+
    If you would like to set such things as the HTTP-Verb, Headers or a Body along with the image request, you may do this by defining these properties on the source object:
    
+
    <Image
+  source={{
+    uri: 'https://facebook.github.io/react/logo-og.png',
+    method: 'POST',
+    headers: {
+      Pragma: 'no-cache',
+    },
+    body: 'Your Body goes here',
+  }}
+  style={{width: 400, height: 400}}
+/>
+
    
+
    Uri Data Images
    
+
    Sometimes, you might be getting encoded image data from a REST API call. You can use the 'data:' uri scheme to use these images. Same as for network resources, you will need to manually specify the dimensions of your image.
    
+
    
+
    This is recommended for very small and dynamic images only, like icons in a list from a DB.
    
+
    
+
    // include at least width and height!
+<Image
+  style={{
+    width: 51,
+    height: 51,
+    resizeMode: 'contain',
+  }}
+  source={{
+    uri:
+      'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg==',
+  }}
+/>
+
    
+
    Cache Control (iOS Only)
    
+
    In some cases you might only want to display an image if it is already in the local cache, i.e. a low resolution placeholder until a higher resolution is available. In other cases you do not care if the image is outdated and are willing to display an outdated image to save bandwidth. The cache source property gives you control over how the network layer interacts with the cache.
    
+
      
+
    • default: Use the native platforms default strategy.
      • 
+
    • reload: The data for the URL will be loaded from the originating source. No existing cache data should be used to satisfy a URL load request.
      • 
+
    • force-cache: The existing cached data will be used to satisfy the request, regardless of its age or expiration date. If there is no existing data in the cache corresponding the request, the data is loaded from the originating source.
      • 
+
    • only-if-cached: The existing cache data will be used to satisfy a request, regardless of its age or expiration date. If there is no existing data in the cache corresponding to a URL load request, no attempt is made to load the data from the originating source, and the load is considered to have failed.
      • 
+
    
+
    <Image
+  source={{
+    uri: 'https://facebook.github.io/react/logo-og.png',
+    cache: 'only-if-cached',
+  }}
+  style={{width: 400, height: 400}}
+/>
+
    
+
    Local Filesystem Images
    
+
    See CameraRoll for an example of using local resources that are outside of Images.xcassets.
    
+
    Best Camera Roll Image
    
+
    iOS saves multiple sizes for the same image in your Camera Roll, it is very important to pick the one that's as close as possible for performance reasons. You wouldn't want to use the full quality 3264x2448 image as source when displaying a 200x200 thumbnail. If there's an exact match, React Native will pick it, otherwise it's going to use the first one that's at least 50% bigger in order to avoid blur when resizing from a close size. All of this is done by default so you don't have to worry about writing the tedious (and error prone) code to do it yourself.
    
+
    Why Not Automatically Size Everything?
    
+
    In the browser if you don't give a size to an image, the browser is going to render a 0x0 element, download the image, and then render the image based with the correct size. The big issue with this behavior is that your UI is going to jump all around as images load, this makes for a very bad user experience.
    
+
    In React Native this behavior is intentionally not implemented. It is more work for the developer to know the dimensions (or aspect ratio) of the remote image in advance, but we believe that it leads to a better user experience. Static images loaded from the app bundle via the require('./my-icon.png') syntax can be automatically sized because their dimensions are available immediately at the time of mounting.
    
+
    For example, the result of require('./my-icon.png') might be:
    
+
    {"__packager_asset":true,"uri":"my-icon.png","width":591,"height":573}
+
    
+
    Source as an object
    
+
    In React Native, one interesting decision is that the src attribute is named source and doesn't take a string but an object with a uri attribute.
    
+
    <Image source={{uri: 'something.jpg'}} />
+
    
+
    On the infrastructure side, the reason is that it allows us to attach metadata to this object. For example if you are using require('./my-icon.png'), then we add information about its actual location and size (don't rely on this fact, it might change in the future!). This is also future proofing, for example we may want to support sprites at some point, instead of outputting {uri: ...}, we can output {uri: ..., crop: {left: 10, top: 50, width: 20, height: 40}} and transparently support spriting on all the existing call sites.
    
+
    On the user side, this lets you annotate the object with useful attributes such as the dimension of the image in order to compute the size it's going to be displayed in. Feel free to use it as your data structure to store more information about your image.
    
+
    Background Image via Nesting
    
+
    A common feature request from developers familiar with the web is background-image. To handle this use case, you can use the <ImageBackground> component, which has the same props as <Image>, and add whatever children to it you would like to layer on top of it.
    
+
    You might not want to use <ImageBackground> in some cases, since the implementation is very simple. Refer to <ImageBackground>'s documentation for more insight, and create your own custom component when needed.
    
+
    return (
+  <ImageBackground source={...} style={{width: '100%', height: '100%'}}>
+    <Text>Inside</Text>
+  </ImageBackground>
+);
+
    
+
    Note that you must specify some width and height style attributes.
    
+
    iOS Border Radius Styles
    
+
    Please note that the following corner specific, border radius style properties are currently ignored by iOS's image component:
    
+
      
+
    • borderTopLeftRadius
      • 
+
    • borderTopRightRadius
      • 
+
    • borderBottomLeftRadius
      • 
+
    • borderBottomRightRadius
      • 
+
    
+
    Off-thread Decoding
    
+
    Image decoding can take more than a frame-worth of time. This is one of the major sources of frame drops on the web because decoding is done in the main thread. In React Native, image decoding is done in a different thread. In practice, you already need to handle the case when the image is not downloaded yet, so displaying the placeholder for a few more frames while it is decoding does not require any code change.

    On Windows, you might need to restart the packager if you add new images to your project.
    
+
    Here are some benefits that you get:
    
+
      
+
    1. Same system on iOS and Android.
      2. 
+
    2. Images live in the same folder as your JavaScript code. Components are self-contained.
      3. 
+
    3. No global namespace, i.e. you don't have to worry about name collisions.
      4. 
+
    4. Only the images that are actually used will be packaged into your app.
      5. 
+
    5. Adding and changing images doesn't require app recompilation, just refresh the simulator as you normally do.
      6. 
+
    6. The packager knows the image dimensions, no need to duplicate it in the code.
      7. 
+
    7. Images can be distributed via npm packages.
      8. 
+
    
+
    In order for this to work, the image name in require has to be known statically.
    
+
    // GOOD
+<Image source={require('./my-icon.png')} />;
+
+// BAD
+var icon = this.props.active ? 'my-icon-active' : 'my-icon-inactive';
+<Image source={require('./' + icon + '.png')} />;
+
+// GOOD
+var icon = this.props.active
+  ? require('./my-icon-active.png')
+  : require('./my-icon-inactive.png');
+<Image source={icon} />;
+
    
+
    Note that image sources required this way include size (width, height) info for the Image. If you need to scale the image dynamically (i.e. via flex), you may need to manually set { width: undefined, height: undefined } on the style attribute.
    
+
    Static Non-Image Resources
    
+
    The require syntax described above can be used to statically include audio, video or document files in your project as well. Most common file types are supported including .mp3, .wav, .mp4, .mov, .html and .pdf. See packager defaults for the full list.
    
+
    You can add support for other types by creating a packager config file (see the packager config file for the full list of configuration options).
    
+
    A caveat is that videos must use absolute positioning instead of flexGrow, since size info is not currently passed for non-image assets. This limitation doesn't occur for videos that are linked directly into Xcode or the Assets folder for Android.
    
+
    Images From Hybrid App's Resources
    
+
    If you are building a hybrid app (some UIs in React Native, some UIs in platform code) you can still use images that are already bundled into the app.
    
+
    For images included via Xcode asset catalogs or in the Android drawable folder, use the image name without the extension:
    
+
    <Image source={{uri: 'app_icon'}} style={{width: 40, height: 40}} />
+
    
+
    For images in the Android assets folder, use the asset:/ scheme:
    
+
    <Image source={{uri: 'asset:/app_icon.png'}} style={{width: 40, height: 40}} />
+
    
+
    These approaches provide no safety checks. It's up to you to guarantee that those images are available in the application. Also you have to specify image dimensions manually.
    
+
    Network Images
    
+
    Many of the images you will display in your app will not be available at compile time, or you will want to load some dynamically to keep the binary size down. Unlike with static resources, you will need to manually specify the dimensions of your image. It's highly recommended that you use https as well in order to satisfy App Transport Security requirements on iOS.
    
+
    // GOOD
+<Image source={{uri: 'https://facebook.github.io/react/logo-og.png'}}
+       style={{width: 400, height: 400}} />
+
+// BAD
+<Image source={{uri: 'https://facebook.github.io/react/logo-og.png'}} />
+
    
+
    Network Requests for Images
    
+
    If you would like to set such things as the HTTP-Verb, Headers or a Body along with the image request, you may do this by defining these properties on the source object:
    
+
    <Image
+  source={{
+    uri: 'https://facebook.github.io/react/logo-og.png',
+    method: 'POST',
+    headers: {
+      Pragma: 'no-cache',
+    },
+    body: 'Your Body goes here',
+  }}
+  style={{width: 400, height: 400}}
+/>
+
    
+
    Uri Data Images
    
+
    Sometimes, you might be getting encoded image data from a REST API call. You can use the 'data:' uri scheme to use these images. Same as for network resources, you will need to manually specify the dimensions of your image.
    
+
    
+
    This is recommended for very small and dynamic images only, like icons in a list from a DB.
    
+
    
+
    // include at least width and height!
+<Image
+  style={{
+    width: 51,
+    height: 51,
+    resizeMode: 'contain',
+  }}
+  source={{
+    uri:
+      'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg==',
+  }}
+/>
+
    
+
    Cache Control (iOS Only)
    
+
    In some cases you might only want to display an image if it is already in the local cache, i.e. a low resolution placeholder until a higher resolution is available. In other cases you do not care if the image is outdated and are willing to display an outdated image to save bandwidth. The cache source property gives you control over how the network layer interacts with the cache.
    
+
      
+
    • default: Use the native platforms default strategy.
      • 
+
    • reload: The data for the URL will be loaded from the originating source. No existing cache data should be used to satisfy a URL load request.
      • 
+
    • force-cache: The existing cached data will be used to satisfy the request, regardless of its age or expiration date. If there is no existing data in the cache corresponding the request, the data is loaded from the originating source.
      • 
+
    • only-if-cached: The existing cache data will be used to satisfy a request, regardless of its age or expiration date. If there is no existing data in the cache corresponding to a URL load request, no attempt is made to load the data from the originating source, and the load is considered to have failed.
      • 
+
    
+
    <Image
+  source={{
+    uri: 'https://facebook.github.io/react/logo-og.png',
+    cache: 'only-if-cached',
+  }}
+  style={{width: 400, height: 400}}
+/>
+
    
+
    Local Filesystem Images
    
+
    See CameraRoll for an example of using local resources that are outside of Images.xcassets.
    
+
    Best Camera Roll Image
    
+
    iOS saves multiple sizes for the same image in your Camera Roll, it is very important to pick the one that's as close as possible for performance reasons. You wouldn't want to use the full quality 3264x2448 image as source when displaying a 200x200 thumbnail. If there's an exact match, React Native will pick it, otherwise it's going to use the first one that's at least 50% bigger in order to avoid blur when resizing from a close size. All of this is done by default so you don't have to worry about writing the tedious (and error prone) code to do it yourself.
    
+
    Why Not Automatically Size Everything?
    
+
    In the browser if you don't give a size to an image, the browser is going to render a 0x0 element, download the image, and then render the image based with the correct size. The big issue with this behavior is that your UI is going to jump all around as images load, this makes for a very bad user experience.
    
+
    In React Native this behavior is intentionally not implemented. It is more work for the developer to know the dimensions (or aspect ratio) of the remote image in advance, but we believe that it leads to a better user experience. Static images loaded from the app bundle via the require('./my-icon.png') syntax can be automatically sized because their dimensions are available immediately at the time of mounting.
    
+
    For example, the result of require('./my-icon.png') might be:
    
+
    {"__packager_asset":true,"uri":"my-icon.png","width":591,"height":573}
+
    
+
    Source as an object
    
+
    In React Native, one interesting decision is that the src attribute is named source and doesn't take a string but an object with a uri attribute.
    
+
    <Image source={{uri: 'something.jpg'}} />
+
    
+
    On the infrastructure side, the reason is that it allows us to attach metadata to this object. For example if you are using require('./my-icon.png'), then we add information about its actual location and size (don't rely on this fact, it might change in the future!). This is also future proofing, for example we may want to support sprites at some point, instead of outputting {uri: ...}, we can output {uri: ..., crop: {left: 10, top: 50, width: 20, height: 40}} and transparently support spriting on all the existing call sites.
    
+
    On the user side, this lets you annotate the object with useful attributes such as the dimension of the image in order to compute the size it's going to be displayed in. Feel free to use it as your data structure to store more information about your image.
    
+
    Background Image via Nesting
    
+
    A common feature request from developers familiar with the web is background-image. To handle this use case, you can use the <ImageBackground> component, which has the same props as <Image>, and add whatever children to it you would like to layer on top of it.
    
+
    You might not want to use <ImageBackground> in some cases, since the implementation is very simple. Refer to <ImageBackground>'s documentation for more insight, and create your own custom component when needed.
    
+
    return (
+  <ImageBackground source={...} style={{width: '100%', height: '100%'}}>
+    <Text>Inside</Text>
+  </ImageBackground>
+);
+
    
+
    Note that you must specify some width and height style attributes.
    
+
    iOS Border Radius Styles
    
+
    Please note that the following corner specific, border radius style properties are currently ignored by iOS's image component:
    
+
      
+
    • borderTopLeftRadius
      • 
+
    • borderTopRightRadius
      • 
+
    • borderBottomLeftRadius
      • 
+
    • borderBottomRightRadius
      • 
+
    
+
    Off-thread Decoding
    
+
    Image decoding can take more than a frame-worth of time. This is one of the major sources of frame drops on the web because decoding is done in the main thread. In React Native, image decoding is done in a different thread. In practice, you already need to handle the case when the image is not downloaded yet, so displaying the placeholder for a few more frames while it is decoding does not require any code change.

    Improving User Experience
    Configure text inputs
    
+
    Entering text on touch phone is a challenge - small screen, software keyboard. But based on what kind of data you need, you can make it easier by properly configuring the text inputs:
    
+
      
+
    • Focus the first field automatically
      • 
+
    • Use placeholder text as an example of expected data format
      • 
+
    • Enable or disable autocapitalization and autocorrect
      • 
+
    • Choose keyboard type (e.g. email, numeric)
      • 
+
    • Make sure the return button focuses the next field or submits the form
      • 
+
    
+
    Check out TextInput docs for more configuration options.
    
+
+
    Try it on your phone
    
+
    Manage layout when keyboard is visible
    
+
    Software keyboard takes almost half of the screen. If you have interactive elements that can get covered by the keyboard, make sure they are still accessible by using the KeyboardAvoidingView component.
    
+
+
    Try it on your phone
    
+
    Make tappable areas larger
    
+
    On mobile phones it's hard to be very precise when pressing buttons. Make sure all interactive elements are 44x44 or larger. One way to do this is to leave enough space for the element, padding, minWidth and minHeight style values can be useful for that. Alternatively, you can use hitSlop prop to increase interactive area without affecting the layout. Here's a demo:
    
+
+
    Try it on your phone
    
+
    Use Android Ripple
    
+
    Android API 21+ uses the material design ripple to provide user with feedback when they touch an interactable area on the screen. React Native exposes this through the TouchableNativeFeedback component. Using this touchable effect instead of opacity or highlight will often make your app feel much more fitting on the platform. That said, you need to be careful when using it because it doesn't work on iOS or on Android API < 21, so you will need to fallback to using one of the other Touchable components on iOS. You can use a library like react-native-platform-touchable to handle the platform differences for you.
    
+
+
    Try it on your phone
    
+
    Screen orientation lock
    
+
    Multiple screen orientations should work fine by default unless you're using Dimensions API and don't handle orientation changes. If you don't want to support multiple screen orientations, you can lock the screen orientation to either portrait or landscape.
    
+
    On iOS, in the General tab and Deployment Info section of Xcode enable the Device Orientation you want to support (ensure you have selected iPhone from the Devices menu when making the changes). For Android, open the AndroidManifest.xml file and within the activity element add 'android:screenOrientation="portrait"' to lock to portrait or 'android:screenOrientation="landscape"' to lock to landscape.

+InputAccessoryView · React Native
    0.58
    Edit
    InputAccessoryView
    A component which enables customization of the keyboard input accessory view on iOS. The input accessory view is displayed above the keyboard whenever a TextInput has focus. This component can be used to create custom toolbars.
    
+
    To use this component wrap your custom toolbar with the InputAccessoryView component, and set a nativeID. Then, pass that nativeID as the inputAccessoryViewID of whatever TextInput you desire. A simple example:
    
+
    import React, { Component } from 'react';
+import { View, ScrollView, AppRegistry, TextInput, InputAccessoryView, Button } from 'react-native';
+
+export default class UselessTextInput extends Component {
+  constructor(props) {
+    super(props);
+    this.state = {text: 'Placeholder Text'};
+  }
+
+  render() {
+    const inputAccessoryViewID = "uniqueID";
+    return (
+      <View>
+        <ScrollView keyboardDismissMode="interactive">
+          <TextInput
+            style={{
+              padding: 10,
+              paddingTop: 50,
+            }}
+            inputAccessoryViewID={inputAccessoryViewID}
+            onChangeText={text => this.setState({text})}
+            value={this.state.text}
+          />
+        </ScrollView>
+        <InputAccessoryView nativeID={inputAccessoryViewID}>
+          <Button
+            onPress={() => this.setState({text: 'Placeholder Text'})}
+            title="Reset Text"
+          />
+        </InputAccessoryView>
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);
+
    
+
+
    This component can also be used to create sticky text inputs (text inputs which are anchored to the top of the keyboard). To do this, wrap a TextInput with the InputAccessoryView component, and don't set a nativeID. For an example, look at InputAccessoryViewExample.js.

    InputAccessoryView
    A component which enables customization of the keyboard input accessory view on iOS. The input accessory view is displayed above the keyboard whenever a TextInput has focus. This component can be used to create custom toolbars.
    
+
    To use this component wrap your custom toolbar with the InputAccessoryView component, and set a nativeID. Then, pass that nativeID as the inputAccessoryViewID of whatever TextInput you desire. A simple example:
    
+
    import React, { Component } from 'react';
+import { View, ScrollView, AppRegistry, TextInput, InputAccessoryView, Button } from 'react-native';
+
+export default class UselessTextInput extends Component {
+  constructor(props) {
+    super(props);
+    this.state = {text: 'Placeholder Text'};
+  }
+
+  render() {
+    const inputAccessoryViewID = "uniqueID";
+    return (
+      <View>
+        <ScrollView keyboardDismissMode="interactive">
+          <TextInput
+            style={{
+              padding: 10,
+              paddingTop: 50,
+            }}
+            inputAccessoryViewID={inputAccessoryViewID}
+            onChangeText={text => this.setState({text})}
+            value={this.state.text}
+          />
+        </ScrollView>
+        <InputAccessoryView nativeID={inputAccessoryViewID}>
+          <Button
+            onPress={() => this.setState({text: 'Placeholder Text'})}
+            title="Reset Text"
+          />
+        </InputAccessoryView>
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App

    Integration with Existing Apps
    
+
    React Native is great when you are starting a new mobile app from scratch. However, it also works well for adding a single view or user flow to existing native applications. With a few steps, you can add new React Native based features, screens, views, etc.
    
+
    The specific steps are different depending on what platform you're targeting.
    
+
    
+  
      
+    
+    
+    
+  
    
+
    
+
    
+
    Key Concepts
    
+
    
+
    The keys to integrating React Native components into your iOS application are to:
    
+
      
+
    1. Set up React Native dependencies and directory structure.
      2. 
+
    2. Understand what React Native components you will use in your app.
      3. 
+
    3. Add these components as dependencies using CocoaPods.
      4. 
+
    4. Develop your React Native components in JavaScript.
      5. 
+
    5. Add a RCTRootView to your iOS app. This view will serve as the container for your React Native component.
      6. 
+
    6. Start the React Native server and run your native application.
      7. 
+
    7. Verify that the React Native aspect of your application works as expected.
      8. 
+
    
+
    
+
    The keys to integrating React Native components into your Android application are to:
    
+
      
+
    1. Set up React Native dependencies and directory structure.
      2. 
+
    2. Develop your React Native components in JavaScript.
      3. 
+
    3. Add a ReactRootView to your Android app. This view will serve as the container for your React Native component.
      4. 
+
    4. Start the React Native server and run your native application.
      5. 
+
    5. Verify that the React Native aspect of your application works as expected.
      6. 
+
    
+
    
+
    Prerequisites
    
+
    
+
    Follow the instructions for building apps with native code from the Getting Started guide to configure your development environment for building React Native apps for iOS.
    
+
    1. Set up directory structure
    
+
    To ensure a smooth experience, create a new folder for your integrated React Native project, then copy your existing iOS project to a /ios subfolder.
    
+
    
+
    Follow the instructions for building apps with native code from the Getting Started guide to configure your development environment for building React Native apps for Android.
    
+
    1. Set up directory structure
    
+
    To ensure a smooth experience, create a new folder for your integrated React Native project, then copy your existing Android project to an /android subfolder.
    
+
    
+
    2. Install JavaScript dependencies
    
+
    Go to the root directory for your project and create a new package.json file with the following contents:
    
+
    {
+  "name": "MyReactNativeApp",
+  "version": "0.0.1",
+  "private": true,
+  "scripts": {
+    "start": "node node_modules/react-native/local-cli/cli.js start"
+  }
+}
+
    
+
    Next, make sure you have installed the yarn package manager.
    
+
    Install the react and react-native packages. Open a terminal or command prompt, then navigate to the directory with your package.json file and run:
    
+
    $ yarn add react-native
+
    
+
    This will print a message similar to the following (scroll up in the yarn output to see it):
    
+
    
+
    warning "react-native@0.52.2" has unmet peer dependency "react@16.2.0".
    
+
    
+
    This is OK, it means we also need to install React:
    
+
    $ yarn add react@version_printed_above
+
    
+
    Yarn has created a new /node_modules folder. This folder stores all the JavaScript dependencies required to build your project.
    
+
    Add node_modules/ to your .gitignore file.
    
+
    
+
    3. Install CocoaPods
    
+
    CocoaPods is a package management tool for iOS and macOS development. We use it to add the actual React Native framework code locally into your current project.
    
+
    We recommend installing CocoaPods using Homebrew.
    
+
    $ brew install cocoapods
+
    
+
    
+
    It is technically possible not to use CocoaPods, but that would require manual library and linker additions that would overly complicate this process.
    
+
    
+
    
+
    Adding React Native to your app
    
+
    
+
    Assume the app for integration is a 2048 game. Here is what the main menu of the native application looks like without React Native.

+
    
+
    Before RN Integration
    
+
    Command Line Tools for Xcode
    
+
    Install the Command Line Tools. Choose "Preferences..." in the Xcode menu. Go to the Locations panel and install the tools by selecting the most recent version in the Command Line Tools dropdown.
    
+
    Xcode Command Line Tools
    
+
    Configuring CocoaPods dependencies
    
+
    Before you integrate React Native into your application, you will want to decide what parts of the React Native framework you would like to integrate. We will use CocoaPods to specify which of these "subspecs" your app will depend on.
    
+
    The list of supported subspecs is available in /node_modules/react-native/React.podspec. They are generally named by functionality. For example, you will generally always want the Core subspec. That will get you the AppRegistry, StyleSheet, View and other core React Native libraries. If you want to add the React Native Text library (e.g., for <Text> elements), then you will need the RCTText subspec. If you want the Image library (e.g., for <Image> elements), then you will need the RCTImage subspec.
    
+
    You can specify which subspecs your app will depend on in a Podfile file. The easiest way to create a Podfile is by running the CocoaPods init command in the /ios subfolder of your project:
    
+
    $ pod init
+
    
+
    The Podfile will contain a boilerplate setup that you will tweak for your integration purposes. In the end, Podfile should look something similar to this:
    
+
    
+
    # The target name is most likely the name of your project.
+target 'NumberTileGame' do
+
+  # Your 'node_modules' directory is probably in the root of your project,
+  # but if not, adjust the `:path` accordingly
+  pod 'React', :path => '../node_modules/react-native', :subspecs => [
+    'Core',
+    'CxxBridge', # Include this for RN >= 0.47
+    'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
+    'RCTText',
+    'RCTNetwork',
+    'RCTWebSocket', # Needed for debugging
+    'RCTAnimation', # Needed for FlatList and animations running on native UI thread
+    # Add any other subspecs you want to use in your project
+  ]
+  # Explicitly include Yoga if you are using RN >= 0.42.0
+  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
+
+  # Third party deps podspec link
+  pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
+  pod 'glog', :podspec => '../node_modules/react-native/third-party-podspecs/glog.podspec'
+  pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'
+
+end
+
    
+
    
+
    source 'https://github.com/CocoaPods/Specs.git'
+
+# Required for Swift apps
+platform :ios, '8.0'
+use_frameworks!
+
+# The target name is most likely the name of your project.
+target 'swift-2048' do
+
+  # Your 'node_modules' directory is probably in the root of your project,
+  # but if not, adjust the `:path` accordingly
+  pod 'React', :path => '../node_modules/react-native', :subspecs => [
+    'Core',
+    'CxxBridge', # Include this for RN >= 0.47
+    'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
+    'RCTText',
+    'RCTNetwork',
+    'RCTWebSocket', # needed for debugging
+    # Add any other subspecs you want to use in your project
+  ]
+  # Explicitly include Yoga if you are using RN >= 0.42.0
+  pod "yoga", :path => "../node_modules/react-native/ReactCommon/yoga"
+
+  # Third party deps podspec link
+  pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
+  pod 'glog', :podspec => '../node_modules/react-native/third-party-podspecs/glog.podspec'
+  pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'
+
+end
+
    
+
    
+
    After you have created your Podfile, you are ready to install the React Native pod.
    
+
    $ pod install
+
    
+
    You should see output such as:
    
+
    Analyzing dependencies
+Fetching podspec for `React` from `../node_modules/react-native`
+Downloading dependencies
+Installing React (0.26.0)
+Generating Pods project
+Integrating client project
+Sending stats
+Pod installation complete! There are 3 dependencies from the Podfile and 1 total pod installed.
+
    
+
    
+
    If this fails with errors mentioning xcrun, make sure that in Xcode in Preferences > Locations the Command Line Tools are assigned.
    
+
    
+
    
+
    
+
    If you get a warning such as "The swift-2048 [Debug] target overrides the FRAMEWORK_SEARCH_PATHS build setting defined in Pods/Target Support Files/Pods-swift-2048/Pods-swift-2048.debug.xcconfig. This can lead to problems with the CocoaPods installation", then make sure the Framework Search Paths in Build Settings for both Debug and Release only contain $(inherited).
    
+
    
+
    
+
    Code integration
    
+
    Now we will actually modify the native iOS application to integrate React Native. For our 2048 sample app, we will add a "High Score" screen in React Native.
    
+
    The React Native component
    
+
    The first bit of code we will write is the actual React Native code for the new "High Score" screen that will be integrated into our application.
    
+
    1. Create a index.js file
    
+
    First, create an empty index.js file in the root of your React Native project.
    
+
    index.js is the starting point for React Native applications, and it is always required. It can be a small file that requires other file that are part of your React Native component or application, or it can contain all the code that is needed for it. In our case, we will just put everything in index.js.
    
+
    2. Add your React Native code
    
+
    In your index.js, create your component. In our sample here, we will add simple <Text> component within a styled <View>
    
+
    import React from 'react';
+import {AppRegistry, StyleSheet, Text, View} from 'react-native';
+
+class RNHighScores extends React.Component {
+  render() {
+    var contents = this.props['scores'].map((score) => (
+      <Text key={score.name}>
+        {score.name}:{score.value}
+        {'\n'}
+      </Text>
+    ));
+    return (
+      <View style={styles.container}>
+        <Text style={styles.highScoresTitle}>2048 High Scores!</Text>
+        <Text style={styles.scores}>{contents}</Text>
+      </View>
+    );
+  }
+}
+
+const styles = StyleSheet.create({
+  container: {
+    flex: 1,
+    justifyContent: 'center',
+    alignItems: 'center',
+    backgroundColor: '#FFFFFF',
+  },
+  highScoresTitle: {
+    fontSize: 20,
+    textAlign: 'center',
+    margin: 10,
+  },
+  scores: {
+    textAlign: 'center',
+    color: '#333333',
+    marginBottom: 5,
+  },
+});
+
+// Module name
+AppRegistry.registerComponent('RNHighScores', () => RNHighScores);
+
    
+
    
+
    RNHighScores is the name of your module that will be used when you add a view to React Native from within your iOS application.
    
+
    
+
    The Magic: RCTRootView
    
+
    Now that your React Native component is created via index.js, you need to add that component to a new or existing ViewController. The easiest path to take is to optionally create an event path to your component and then add that component to an existing ViewController.
    
+
    We will tie our React Native component with a new native view in the ViewController that will actually host it called RCTRootView .
    
+
    1. Create an Event Path
    
+
    You can add a new link on the main game menu to go to the "High Score" React Native page.
    
+
    Event Path
    
+
    2. Event Handler
    
+
    We will now add an event handler from the menu link. A method will be added to the main ViewController of your application. This is where RCTRootView comes into play.
    
+
    When you build a React Native application, you use the React Native packager to create an index.bundle that will be served by the React Native server. Inside index.bundle will be our RNHighScore module. So, we need to point our RCTRootView to the location of the index.bundle resource (via NSURL) and tie it to the module.
    
+
    We will, for debugging purposes, log that the event handler was invoked. Then, we will create a string with the location of our React Native code that exists inside the index.bundle. Finally, we will create the main RCTRootView. Notice how we provide RNHighScores as the moduleName that we created above when writing the code for our React Native component.
    
+
    
+
    First import the RCTRootView header.
    
+
    #import <React/RCTRootView.h>
+
    
+
    
+
    The initialProperties are here for illustration purposes so we have some data for our high score screen. In our React Native component, we will use this.props to get access to that data.
    
+
    
+
    - (IBAction)highScoreButtonPressed:(id)sender {
+    NSLog(@"High Score Button Pressed");
+    NSURL *jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.bundle?platform=ios"];
+
+    RCTRootView *rootView =
+      [[RCTRootView alloc] initWithBundleURL: jsCodeLocation
+                                  moduleName: @"RNHighScores"
+                           initialProperties:
+                             @{
+                               @"scores" : @[
+                                 @{
+                                   @"name" : @"Alex",
+                                   @"value": @"42"
+                                  },
+                                 @{
+                                   @"name" : @"Joel",
+                                   @"value": @"10"
+                                 }
+                               ]
+                             }
+                               launchOptions: nil];
+    UIViewController *vc = [[UIViewController alloc] init];
+    vc.view = rootView;
+    [self presentViewController:vc animated:YES completion:nil];
+}
+
    
+
    
+
    Note that RCTRootView initWithURL starts up a new JSC VM. To save resources and simplify the communication between RN views in different parts of your native app, you can have multiple views powered by React Native that are associated with a single JS runtime. To do that, instead of using [RCTRootView alloc] initWithURL, use RCTBridge initWithBundleURL to create a bridge and then use RCTRootView initWithBridge.
    
+
    
+
    
+
    First import the React library.
    
+
    import React
+
    
+
    
+
    The initialProperties are here for illustration purposes so we have some data for our high score screen. In our React Native component, we will use this.props to get access to that data.
    
+
    
+
    @IBAction func highScoreButtonTapped(sender : UIButton) {
+  NSLog("Hello")
+  let jsCodeLocation = URL(string: "http://localhost:8081/index.bundle?platform=ios")
+  let mockData:NSDictionary = ["scores":
+      [
+          ["name":"Alex", "value":"42"],
+          ["name":"Joel", "value":"10"]
+      ]
+  ]
+
+  let rootView = RCTRootView(
+      bundleURL: jsCodeLocation,
+      moduleName: "RNHighScores",
+      initialProperties: mockData as [NSObject : AnyObject],
+      launchOptions: nil
+  )
+  let vc = UIViewController()
+  vc.view = rootView
+  self.present(vc, animated: true, completion: nil)
+}
+
    
+
    
+
    Note that RCTRootView bundleURL starts up a new JSC VM. To save resources and simplify the communication between RN views in different parts of your native app, you can have multiple views powered by React Native that are associated with a single JS runtime. To do that, instead of using RCTRootView bundleURL, use RCTBridge initWithBundleURL to create a bridge and then use RCTRootView initWithBridge.
    
+
    
+
    
+
    
+
    When moving your app to production, the NSURL can point to a pre-bundled file on disk via something like [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];. You can use the react-native-xcode.sh script in node_modules/react-native/scripts/ to generate that pre-bundled file.

    One of the easier ways to do this is to open the view in the storyboard and right click on the new link. Select something such as the Touch Up Inside event, drag that to the storyboard and then select the created method from the list provided.
    
+
    
+
    Test your integration
    
+
    You have now done all the basic steps to integrate React Native with your current application. Now we will start the React Native packager to build the index.bundle package and the server running on localhost to serve it.
    
+
    1. Add App Transport Security exception
    
+
    Apple has blocked implicit cleartext HTTP resource loading. So we need to add the following our project's Info.plist (or equivalent) file.
    
+
    <key>NSAppTransportSecurity</key>
+<dict>
+    <key>NSExceptionDomains</key>
+    <dict>
+        <key>localhost</key>
+        <dict>
+            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
+            <true/>
+        </dict>
+    </dict>
+</dict>
+
    
+
    
+
    App Transport Security is good for your users. Make sure to re-enable it prior to releasing your app for production.
    
+
    
+
    2. Run the packager
    
+
    To run your app, you need to first start the development server. To do this, simply run the following command in the root directory of your React Native project:
    
+
    $ npm start
+
    
+
    3. Run the app
    
+
    If you are using Xcode or your favorite editor, build and run your native iOS application as normal. Alternatively, you can run the app from the command line using:
    
+
    # From the root of your project
+$ react-native run-ios
+
    
+
    In our sample application, you should see the link to the "High Scores" and then when you click on that you will see the rendering of your React Native component.
    
+
    Here is the native application home screen:
    
+
    Home Screen
    
+
    Here is the React Native high score screen:
    
+
    High Scores
    
+
    
+
    If you are getting module resolution issues when running your application please see this GitHub issue for information and possible resolution. This comment seemed to be the latest possible resolution.
    
+
    
+
    See the Code
    
+
    
+
    You can examine the code that added the React Native screen to our sample app on GitHub.

+
    
+
    Adding React Native to your app
    
+
    Configuring maven
    
+
    Add the React Native dependency to your app's build.gradle file:
    
+
    dependencies {
+    implementation 'com.android.support:appcompat-v7:27.1.1'
+    ...
+    implementation "com.facebook.react:react-native:+" // From node_modules
+}
+
    
+
    
+
    If you want to ensure that you are always using a specific React Native version in your native build, replace + with an actual React Native version you've downloaded from npm.
    
+
    
+
    Add an entry for the local React Native maven directory to build.gradle. Be sure to add it to the "allprojects" block, above other maven repositories:
    
+
    allprojects {
+    repositories {
+        maven {
+            // All of React Native (JS, Android binaries) is installed from npm
+            url "$rootDir/../node_modules/react-native/android"
+        }
+        ...
+    }
+    ...
+}
+
    
+
    
+
    Make sure that the path is correct! You shouldn’t run into any “Failed to resolve: com.facebook.react:react-native:0.x.x" errors after running Gradle sync in Android Studio.
    
+
    
+
    Configuring permissions
    
+
    Next, make sure you have the Internet permission in your AndroidManifest.xml:
    
+
    <uses-permission android:name="android.permission.INTERNET" />
+
    
+
    If you need to access to the DevSettingsActivity add to your AndroidManifest.xml:
    
+
    <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
+
    
+
    This is only used in dev mode when reloading JavaScript from the development server, so you can strip this in release builds if you need to.
    
+
    Network Security Config (API level 28+)
    
+
    
+
    Starting with Android 9 (API level 28), cleartext traffic is disabled by default; this prevents your application from connecting to the React Native packager. These changes add domain rules that specifically allow cleartext traffic to the packager IPs.
    
+
    
+
    1. Create the following resource files
    
+
    app/src/debug/res/xml/network_security_config.xml:
    
+
    <?xml version="1.0" encoding="utf-8"?>
+<network-security-config>
+  <!-- allow cleartext traffic for React Native packager ips in debug -->
+  <domain-config cleartextTrafficPermitted="true">
+    <domain includeSubdomains="false">localhost</domain>
+    <domain includeSubdomains="false">10.0.2.2</domain>
+    <domain includeSubdomains="false">10.0.3.2</domain>
+  </domain-config>
+</network-security-config>
+
    
+
    app/src/release/res/xml/network_security_config.xml:
    
+
    <?xml version="1.0" encoding="utf-8"?>
+<network-security-config>
+  <!-- deny cleartext traffic for React Native packager ips in release -->
+  <domain-config cleartextTrafficPermitted="false">
+    <domain includeSubdomains="false">localhost</domain>
+    <domain includeSubdomains="false">10.0.2.2</domain>
+    <domain includeSubdomains="false">10.0.3.2</domain>
+  </domain-config>
+</network-security-config>
+
    
+
    2. Apply the config to your AndroidManifest.xml
    
+
    <!-- ... -->
+<application
+  android:networkSecurityConfig="@xml/network_security_config">
+  <!-- ... -->
+</application>
+<!-- ... -->
+
    
+
    To learn more about Network Security Config and the cleartext traffic policy see this link.
    
+
    Code integration
    
+
    Now we will actually modify the native Android application to integrate React Native.
    
+
    The React Native component
    
+
    The first bit of code we will write is the actual React Native code for the new "High Score" screen that will be integrated into our application.
    
+
    1. Create a index.js file
    
+
    First, create an empty index.js file in the root of your React Native project.
    
+
    index.js is the starting point for React Native applications, and it is always required. It can be a small file that requires other file that are part of your React Native component or application, or it can contain all the code that is needed for it. In our case, we will just put everything in index.js.
    
+
    2. Add your React Native code
    
+
    In your index.js, create your component. In our sample here, we will add simple <Text> component within a styled <View>:
    
+
    import React from 'react';
+import {AppRegistry, StyleSheet, Text, View} from 'react-native';
+
+class HelloWorld extends React.Component {
+  render() {
+    return (
+      <View style={styles.container}>
+        <Text style={styles.hello}>Hello, World</Text>
+      </View>
+    );
+  }
+}
+var styles = StyleSheet.create({
+  container: {
+    flex: 1,
+    justifyContent: 'center',
+  },
+  hello: {
+    fontSize: 20,
+    textAlign: 'center',
+    margin: 10,
+  },
+});
+
+AppRegistry.registerComponent('MyReactNativeApp', () => HelloWorld);
+
    
+
    3. Configure permissions for development error overlay
    
+
    If your app is targeting the Android API level 23 or greater, make sure you have the permission android.permission.SYSTEM_ALERT_WINDOW enabled for the development build. You can check this with Settings.canDrawOverlays(this);. This is required in dev builds because React Native development errors must be displayed above all the other windows. Due to the new permissions system introduced in the API level 23 (Android M), the user needs to approve it. This can be achieved by adding the following code to your Activity's in onCreate() method.
    
+
    private final int OVERLAY_PERMISSION_REQ_CODE = 1;  // Choose any value
+
+...
+
+if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
+    if (!Settings.canDrawOverlays(this)) {
+        Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
+                                   Uri.parse("package:" + getPackageName()));
+        startActivityForResult(intent, OVERLAY_PERMISSION_REQ_CODE);
+    }
+}
+
    
+
    Finally, the onActivityResult() method (as shown in the code below) has to be overridden to handle the permission Accepted or Denied cases for consistent UX. Also, for integrating Native Modules which use startActivityForResult, we need to pass the result to the onActivityResult method of our ReactInstanceManager instance.
    
+
    @Override
+protected void onActivityResult(int requestCode, int resultCode, Intent data) {
+    if (requestCode == OVERLAY_PERMISSION_REQ_CODE) {
+        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
+            if (!Settings.canDrawOverlays(this)) {
+                // SYSTEM_ALERT_WINDOW permission not granted
+            }
+        }
+    }
+    mReactInstanceManager.onActivityResult( this, requestCode, resultCode, data );
+}
+
    
+
    The Magic: ReactRootView
    
+
    Let's add some native code in order to start the React Native runtime and tell it to render our JS component. To do this, we're going to create an Activity that creates a ReactRootView, starts a React application inside it and sets it as the main content view.
    
+
    
+
    If you are targetting Android version <5, use the AppCompatActivity class from the com.android.support:appcompat package instead of Activity.
    
+
    
+
    public class MyReactActivity extends Activity implements DefaultHardwareBackBtnHandler {
+    private ReactRootView mReactRootView;
+    private ReactInstanceManager mReactInstanceManager;
+
+    @Override
+    protected void onCreate(Bundle savedInstanceState) {
+        super.onCreate(savedInstanceState);
+
+        mReactRootView = new ReactRootView(this);
+        mReactInstanceManager = ReactInstanceManager.builder()
+                .setApplication(getApplication())
+                .setCurrentActivity(this)
+                .setBundleAssetName("index.android.bundle")
+                .setJSMainModulePath("index")
+                .addPackage(new MainReactPackage())
+                .setUseDeveloperSupport(BuildConfig.DEBUG)
+                .setInitialLifecycleState(LifecycleState.RESUMED)
+                .build();
+        // The string here (e.g. "MyReactNativeApp") has to match
+        // the string in AppRegistry.registerComponent() in index.js
+        mReactRootView.startReactApplication(mReactInstanceManager, "MyReactNativeApp", null);
+
+        setContentView(mReactRootView);
+    }
+
+    @Override
+    public void invokeDefaultOnBackPressed() {
+        super.onBackPressed();
+    }
+}
+
    
+
    
+
    If you are using a starter kit for React Native, replace the "HelloWorld" string with the one in your index.js file (it’s the first argument to the AppRegistry.registerComponent() method).
    
+
    
+
    If you are using Android Studio, use Alt + Enter to add all missing imports in your MyReactActivity class. Be careful to use your package’s BuildConfig and not the one from the facebook package.
    
+
    We need set the theme of MyReactActivity to Theme.AppCompat.Light.NoActionBar because some React Native UI components rely on this theme.
    
+
    <activity
+  android:name=".MyReactActivity"
+  android:label="@string/app_name"
+  android:theme="@style/Theme.AppCompat.Light.NoActionBar">
+</activity>
+
    
+
    
+
    A ReactInstanceManager can be shared by multiple activities and/or fragments. You will want to make your own ReactFragment or ReactActivity and have a singleton holder that holds a ReactInstanceManager. When you need the ReactInstanceManager (e.g., to hook up the ReactInstanceManager to the lifecycle of those Activities or Fragments) use the one provided by the singleton.
    
+
    
+
    Next, we need to pass some activity lifecycle callbacks to the ReactInstanceManager and ReactRootView:
    
+
    @Override
+protected void onPause() {
+    super.onPause();
+
+    if (mReactInstanceManager != null) {
+        mReactInstanceManager.onHostPause(this);
+    }
+}
+
+@Override
+protected void onResume() {
+    super.onResume();
+
+    if (mReactInstanceManager != null) {
+        mReactInstanceManager.onHostResume(this, this);
+    }
+}
+
+@Override
+protected void onDestroy() {
+    super.onDestroy();
+
+    if (mReactInstanceManager != null) {
+        mReactInstanceManager.onHostDestroy(this);
+    }
+    if (mReactRootView != null) {
+        mReactRootView.unmountReactApplication();
+    }
+}
+
    
+
    We also need to pass back button events to React Native:
    
+
    @Override
+ public void onBackPressed() {
+    if (mReactInstanceManager != null) {
+        mReactInstanceManager.onBackPressed();
+    } else {
+        super.onBackPressed();
+    }
+}
+
    
+
    This allows JavaScript to control what happens when the user presses the hardware back button (e.g. to implement navigation). When JavaScript doesn't handle the back button press, your invokeDefaultOnBackPressed method will be called. By default this simply finishes your Activity.
    
+
    Finally, we need to hook up the dev menu. By default, this is activated by (rage) shaking the device, but this is not very useful in emulators. So we make it show when you press the hardware menu button (use Ctrl + M if you're using Android Studio emulator):
    
+
    @Override
+public boolean onKeyUp(int keyCode, KeyEvent event) {
+    if (keyCode == KeyEvent.KEYCODE_MENU && mReactInstanceManager != null) {
+        mReactInstanceManager.showDevOptionsDialog();
+        return true;
+    }
+    return super.onKeyUp(keyCode, event);
+}
+
    
+
    Now your activity is ready to run some JavaScript code.
    
+
    Test your integration
    
+
    You have now done all the basic steps to integrate React Native with your current application. Now we will start the React Native packager to build the index.bundle package and the server running on localhost to serve it.
    
+
    1. Run the packager
    
+
    To run your app, you need to first start the development server. To do this, simply run the following command in the root directory of your React Native project:
    
+
    $ yarn start
+
    
+
    2. Run the app
    
+
    Now build and run your Android app as normal.
    
+
    Once you reach your React-powered activity inside the app, it should load the JavaScript code from the development server and display:
    
+
    Screenshot
    
+
    Creating a release build in Android Studio
    
+
    You can use Android Studio to create your release builds too! It’s as easy as creating release builds of your previously-existing native Android app. There’s just one additional step, which you’ll have to do before every release build. You need to execute the following to create a React Native bundle, which will be included with your native Android app:
    
+
    $ react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/com/your-company-name/app-package-name/src/main/assets/index.android.bundle --assets-dest android/com/your-company-name/app-package-name/src/main/res/
+
    
+
    
+
    Don’t forget to replace the paths with correct ones and create the assets folder if it doesn’t exist.
    
+
    
+
    Now just create a release build of your native app from within Android Studio as usual and you should be good to go!
    
+
    
+
    Now what?
    
+
    At this point you can continue developing your app as usual. Refer to our debugging and deployment docs to learn more about working with React Native.

    Integration with Existing Apps
    
+
    React Native is great when you are starting a new mobile app from scratch. However, it also works well for adding a single view or user flow to existing native applications. With a few steps, you can add new React Native based features, screens, views, etc.
    
+
    The specific steps are different depending on what platform you're targeting.
    
+

    Key Concepts
    
+
    
+
    The keys to integrating React Native components into your iOS application are to:
    
+
      
+
    1. Set up React Native dependencies and directory structure.
      2. 
+
    2. Understand what React Native components you will use in your app.
      3. 
+
    3. Add these components as dependencies using CocoaPods.
      4. 
+
    4. Develop your React Native components in JavaScript.
      5. 
+
    5. Add a RCTRootView to your iOS app. This view will serve as the container for your React Native component.
      6. 
+
    6. Start the React Native server and run your native application.
      7. 
+
    7. Verify that the React Native aspect of your application works as expected.
      8.

+
    Prerequisites
    
+
    
+
    Follow the instructions for building apps with native code from the Getting Started guide to configure your development environment for building React Native apps for iOS.
    
+
    1. Set up directory structure
    
+
    To ensure a smooth experience, create a new folder for your integrated React Native project, then copy your existing iOS project to a /ios subfolder.
    
+
    
+
    Follow the instructions for building apps with native code from the Getting Started guide to configure your development environment for building React Native apps for Android.
    
+
    1. Set up directory structure
    
+
    To ensure a smooth experience, create a new folder for your integrated React Native project, then copy your existing Android project to an /android subfolder.
    
+
    
+
    2. Install JavaScript dependencies
    
+
    Go to the root directory for your project and create a new package.json file with the following contents:
    
+
    {
+  "name": "MyReactNativeApp",
+  "version": "0.0.1",
+  "private": true,
+  "scripts": {
+    "start": "node node_modules/react-native/local-cli/cli.js start"
+  }
+}
+
    
+
    Next, make sure you have installed the yarn package manager.
    
+
    Install the react and react-native packages. Open a terminal or command prompt, then navigate to the directory with your package.json file and run:
    
+
    $ yarn add react-native
+
    
+
    This will print a message similar to the following (scroll up in the yarn output to see it):
    
+
    
+
    warning "react-native@0.52.2" has unmet peer dependency "react@16.2.0".
    
+
    
+
    This is OK, it means we also need to install React:
    
+
    $ yarn add react@version_printed_above
+
    
+
    Yarn has created a new /node_modules folder. This folder stores all the JavaScript dependencies required to build your project.
    
+
    Add node_modules/ to your .gitignore file.
    
+
    
+
    3. Install CocoaPods
    
+
    CocoaPods is a package management tool for iOS and macOS development. We use it to add the actual React Native framework code locally into your current project.
    
+
    We recommend installing CocoaPods using Homebrew.
    
+
    $ brew install cocoapods
+
    
+
    
+
    It is technically possible not to use CocoaPods, but that would require manual library and linker additions that would overly complicate this process.
    
+
    
+
    
+
    Adding React Native to your app
    
+
    
+
    Assume the app for integration is a 2048 game. Here is what the main menu of the native application looks like without React Native.

    Before RN Integration
    
+
    Command Line Tools for Xcode
    
+
    Install the Command Line Tools. Choose "Preferences..." in the Xcode menu. Go to the Locations panel and install the tools by selecting the most recent version in the Command Line Tools dropdown.
    
+
    Xcode Command Line Tools
    
+
    Configuring CocoaPods dependencies
    
+
    Before you integrate React Native into your application, you will want to decide what parts of the React Native framework you would like to integrate. We will use CocoaPods to specify which of these "subspecs" your app will depend on.
    
+
    The list of supported subspecs is available in /node_modules/react-native/React.podspec. They are generally named by functionality. For example, you will generally always want the Core subspec. That will get you the AppRegistry, StyleSheet, View and other core React Native libraries. If you want to add the React Native Text library (e.g., for <Text> elements), then you will need the RCTText subspec. If you want the Image library (e.g., for <Image> elements), then you will need the RCTImage subspec.
    
+
    You can specify which subspecs your app will depend on in a Podfile file. The easiest way to create a Podfile is by running the CocoaPods init command in the /ios subfolder of your project:
    
+
    $ pod init
+
    
+
    The Podfile will contain a boilerplate setup that you will tweak for your integration purposes. In the end, Podfile should look something similar to this:
    
+
    
+
    # The target name is most likely the name of your project.
+target 'NumberTileGame' do
+
+  # Your 'node_modules' directory is probably in the root of your project,
+  # but if not, adjust the `:path` accordingly
+  pod 'React', :path => '../node_modules/react-native', :subspecs => [
+    'Core',
+    'CxxBridge', # Include this for RN >= 0.47

+
    Code integration
    
+
    Now we will actually modify the native iOS application to integrate React Native. For our 2048 sample app, we will add a "High Score" screen in React Native.
    
+
    The React Native component
    
+
    The first bit of code we will write is the actual React Native code for the new "High Score" screen that will be integrated into our application.
    
+
    1. Create a index.js file
    
+
    First, create an empty index.js file in the root of your React Native project.
    
+
    index.js is the starting point for React Native applications, and it is always required. It can be a small file that requires other file that are part of your React Native component or application, or it can contain all the code that is needed for it. In our case, we will just put everything in index.js.
    
+
    2. Add your React Native code
    
+
    In your index.js, create your component. In our sample here, we will add simple <Text> component within a styled <View>
    
+
    import React from 'react';
+import {AppRegistry, StyleSheet, Text, View} from 'react-native';
+
+class RNHighScores extends React.Component {
+  render() {
+    var contents = this.props['scores'].map((score) => (
+      <Text key={score.name}>
+        {score.name}:{score.value}
+        {'\n'}
+      </Text>
+    ));
+    return (
+      <View style={styles.container}>
+        <Text style={styles.highScoresTitle}>2048 High Scores!</Text>
+        <Text style={styles.scores}>{contents}</Text>
+      </View>
+    );
+  }
+}
+
+const styles = StyleSheet.create({
+  container: {
+    flex: 1,
+    justifyContent: 'center',
+    alignItems: 'center',
+    backgroundColor: '#FFFFFF',
+  },
+  highScoresTitle: {
+    fontSize: 20,
+    textAlign: 'center',
+    margin: 10,
+  },
+  scores: {
+    textAlign: 'center',
+    color: '#333333',
+    marginBottom: 5,
+  },
+});
+
+// Module name
+AppRegistry.registerComponent('RNHighScores', () => RNHighScores);
+
    
+
    
+
    RNHighScores is the name of your module that will be used when you add a view to React Native from within your iOS application.
    
+
    
+
    The Magic: RCTRootView
    
+
    Now that your React Native component is created via index.js, you need to add that component to a new or existing ViewController. The easiest path to take is to optionally create an event path to your component and then add that component to an existing ViewController.
    
+
    We will tie our React Native component with a new native view in the ViewController that will actually host it called RCTRootView .
    
+
    1. Create an Event Path
    
+
    You can add a new link on the main game menu to go to the "High Score" React Native page.
    
+
    Event Path
    
+
    2. Event Handler
    
+
    We will now add an event handler from the menu link. A method will be added to the main ViewController of your application. This is where RCTRootView comes into play.
    
+
    When you build a React Native application, you use the React Native packager to create an index.bundle that will be served by the React Native server. Inside index.bundle will be our RNHighScore module. So, we need to point our RCTRootView to the location of the index.bundle resource (via NSURL) and tie it to the module.
    
+
    We will, for debugging purposes, log that the event handler was invoked. Then, we will create a string with the location of our React Native code that exists inside the index.bundle. Finally, we will create the main RCTRootView. Notice how we provide RNHighScores as the moduleName that we created above when writing the code for our React Native component.
    
+
    
+
    First import the RCTRootView header.
    
+
    #import <React/RCTRootView.h>
+
    
+
    
+
    The initialProperties are here for illustration purposes so we have some data for our high score screen. In our React Native component, we will use this.props to get access to that data.
    
+
    
+
    - (IBAction)highScoreButtonPressed:(id)sender {
+    NSLog(@"High Score Button Pressed");
+    NSURL *jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.bundle?platform=ios"];
+
+    RCTRootView *rootView =
+      [[RCTRootView alloc] initWithBundleURL: jsCodeLocation
+                                  moduleName: @"RNHighScores"
+                           initialProperties:
+                             @{
+                               @"scores" : @[
+                                 @{
+                                   @"name" : @"Alex",
+                                   @"value": @"42"
+                                  },
+                                 @{
+                                   @"name" : @"Joel",
+                                   @"value": @"10"
+                                 }
+                               ]
+                             }
+                               launchOptions: nil];
+    UIViewController *vc = [[UIViewController alloc] init];
+    vc.view = rootView;
+    [self presentViewController:vc animated:YES completion:nil];
+}
+
    
+
    
+
    Note that RCTRootView initWithURL starts up a new JSC VM. To save resources and simplify the communication between RN views in different parts of your native app, you can have multiple views powered by React Native that are associated with a single JS runtime. To do that, instead of using [RCTRootView alloc] initWithURL, use RCTBridge initWithBundleURL to create a bridge and then use RCTRootView initWithBridge.
    
+
    
+
    
+
    First import the React library.
    
+
    import React
+
    
+
    
+
    The initialProperties are here for illustration purposes so we have some data for our high score screen. In our React Native component, we will use this.props to get access to that data.
    
+
    
+
    @IBAction func highScoreButtonTapped(sender : UIButton) {
+  NSLog("Hello")
+  let jsCodeLocation = URL(string: "http://localhost:8081/index.bundle?platform=ios")
+  let mockData:NSDictionary = ["scores":
+      [
+          ["name":"Alex", "value":"42"],
+          ["name":"Joel", "value":"10"]
+      ]
+  ]
+
+  let rootView = RCTRootView(
+      bundleURL: jsCodeLocation,
+      moduleName: "RNHighScores",
+      initialProperties: mockData as [NSObject : AnyObject],
+      launchOptions: nil
+  )
+  let vc = UIViewController()
+  vc.view = rootView
+  self.present(vc, animated: true, completion: nil)
+}
+
    
+
    
+
    Note that RCTRootView bundleURL starts up a new JSC VM. To save resources and simplify the communication between RN views in different parts of your native app, you can have multiple views powered by React Native that are associated with a single JS runtime. To do that, instead of using RCTRootView bundleURL, use RCTBridge initWithBundleURL to create a bridge and then use RCTRootView initWithBridge.
    
+
    
+
    
+
    
+
    When moving your app to production, the NSURL can point to a pre-bundled file on disk via something like [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];. You can use the react-native-xcode.sh script in node_modules/react-native/scripts/ to generate that pre-bundled file.
    
+

+
    
+
    
+
    3. Wire Up
    
+
    Wire up the new link in the main menu to the newly added event handler method.
    
+
    Event Path
    
+
    
+
    One of the easier ways to do this is to open the view in the storyboard and right click on the new link. Select something such as the Touch Up Inside event, drag that to the storyboard and then select the created method from the list provided.
    
+
    
+
    Test your integration
    
+
    You have now done all the basic steps to integrate React Native with your current application. Now we will start the React Native packager to build the index.bundle package and the server running on localhost to serve it.
    
+
    1. Add App Transport Security exception
    
+
    Apple has blocked implicit cleartext HTTP resource loading. So we need to add the following our project's Info.plist (or equivalent) file.
    
+
    <key>NSAppTransportSecurity</key>
+<dict>
+    <key>NSExceptionDomains</key>
+    <dict>
+        <key>localhost</key>
+        <dict>
+            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
+            <true/>
+        </dict>
+    </dict>
+</dict>
+
    
+
    
+
    App Transport Security is good for your users. Make sure to re-enable it prior to releasing your app for production.
    
+
    
+
    2. Run the packager
    
+
    To run your app, you need to first start the development server. To do this, simply run the following command in the root directory of your React Native project:
    
+
    $ npm start
+
    
+
    3. Run the app
    
+
    If you are using Xcode or your favorite editor, build and run your native iOS application as normal. Alternatively, you can run the app from the command line using:
    
+
    # From the root of your project
+$ react-native run-ios
+
    
+
    In our sample application, you should see the link to the "High Scores" and then when you click on that you will see the rendering of your React Native component.
    
+
    Here is the native application home screen:
    
+
    Home Screen
    
+
    Here is the React Native high score screen:
    
+
    High Scores
    
+
    
+
    If you are getting module resolution issues when running your application please see this GitHub issue for information and possible resolution. This comment seemed to be the latest possible resolution.
    
+
    
+
    See the Code
    
+
    
+
    You can examine the code that added the React Native screen to our sample app on GitHub.

+
    
+
    Adding React Native to your app
    
+
    Configuring maven
    
+
    Add the React Native dependency to your app's build.gradle file:
    
+
    dependencies {
+    implementation 'com.android.support:appcompat-v7:27.1.1'
+    ...
+    implementation "com.facebook.react:react-native:+" // From node_modules
+}
+
    
+
    
+
    If you want to ensure that you are always using a specific React Native version in your native build, replace + with an actual React Native version you've downloaded from npm.
    
+
    
+
    Add an entry for the local React Native maven directory to build.gradle. Be sure to add it to the "allprojects" block, above other maven repositories:
    
+
    allprojects {
+    repositories {
+        maven {
+            // All of React Native (JS, Android binaries) is installed from npm
+            url "$rootDir/../node_modules/react-native/android"
+        }
+        ...
+    }
+    ...
+}
+
    
+
    
+
    Make sure that the path is correct! You shouldn’t run into any “Failed to resolve: com.facebook.react:react-native:0.x.x" errors after running Gradle sync in Android Studio.
    
+
    
+
    Configuring permissions
    
+
    Next, make sure you have the Internet permission in your AndroidManifest.xml:
    
+
    <uses-permission android:name="android.permission.INTERNET" />
+
    
+
    If you need to access to the DevSettingsActivity add to your AndroidManifest.xml:
    
+
    <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
+
    
+
    This is only used in dev mode when reloading JavaScript from the development server, so you can strip this in release builds if you need to.
    
+
    Network Security Config (API level 28+)
    
+
    
+
    Starting with Android 9 (API level 28), cleartext traffic is disabled by default; this prevents your application from connecting to the React Native packager. These changes add domain rules that specifically allow cleartext traffic to the packager IPs.
    
+
    
+
    1. Create the following resource files
    
+
    app/src/debug/res/xml/network_security_config.xml:
    
+
    <?xml version="1.0" encoding="utf-8"?>
+<network-security-config>
+  <!-- allow cleartext traffic for React Native packager ips in debug -->
+  <domain-config cleartextTrafficPermitted="true">
+    <domain includeSubdomains="false">localhost</domain>
+    <domain includeSubdomains="false">10.0.2.2</domain>
+    <domain includeSubdomains="false">10.0.3.2</domain>
+  </domain-config>
+</network-security-config>
+
    
+
    app/src/release/res/xml/network_security_config.xml:
    
+
    <?xml version="1.0" encoding="utf-8"?>
+<network-security-config>
+  <!-- deny cleartext traffic for React Native packager ips in release -->
+  <domain-config cleartextTrafficPermitted="false">
+    <domain includeSubdomains="false">localhost</domain>
+    <domain includeSubdomains="false">10.0.2.2</domain>
+    <domain includeSubdomains="false">10.0.3.2</domain>
+  </domain-config>
+</network-security-config>
+
    
+
    2. Apply the config to your AndroidManifest.xml
    
+
    <!-- ... -->
+<application
+  android:networkSecurityConfig="@xml/network_security_config">
+  <!-- ... -->
+</application>
+<!-- ... -->
+
    
+
    To learn more about Network Security Config and the cleartext traffic policy see this link.
    
+
    Code integration
    
+
    Now we will actually modify the native Android application to integrate React Native.
    
+
    The React Native component
    
+
    The first bit of code we will write is the actual React Native code for the new "High Score" screen that will be integrated into our application.
    
+
    1. Create a index.js file
    
+
    First, create an empty index.js file in the root of your React Native project.
    
+
    index.js is the starting point for React Native applications, and it is always required. It can be a small file that requires other file that are part of your React Native component or application, or it can contain all the code that is needed for it. In our case, we will just put everything in index.js.
    
+
    2. Add your React Native code
    
+
    In your index.js, create your component. In our sample here, we will add simple <Text> component within a styled <View>:
    
+
    import React from 'react';
+import {AppRegistry, StyleSheet, Text, View} from 'react-native';
+
+class HelloWorld extends React.Component {
+  render() {
+    return (
+      <View style={styles.container}>
+        <Text style={styles.hello}>Hello, World</Text>
+      </View>
+    );
+  }
+}
+var styles = StyleSheet.create({
+  container: {
+    flex: 1,
+    justifyContent: 'center',
+  },
+  hello: {
+    fontSize: 20,
+    textAlign: 'center',
+    margin: 10,
+  },
+});
+
+AppRegistry.registerComponent('MyReactNativeApp', () => HelloWorld);
+
    
+
    3. Configure permissions for development error overlay
    
+
    If your app is targeting the Android API level 23 or greater, make sure you have the permission android.permission.SYSTEM_ALERT_WINDOW enabled for the development build. You can check this with Settings.canDrawOverlays(this);. This is required in dev builds because React Native development errors must be displayed above all the other windows. Due to the new permissions system introduced in the API level 23 (Android M), the user needs to approve it. This can be achieved by adding the following code to your Activity's in onCreate() method.
    
+
    private final int OVERLAY_PERMISSION_REQ_CODE = 1;  // Choose any value
+
+...
+
+if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
+    if (!Settings.canDrawOverlays(this)) {
+        Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
+                                   Uri.parse("package:" + getPackageName()));
+        startActivityForResult(intent, OVERLAY_PERMISSION_REQ_CODE);
+    }
+}
+
    
+
    Finally, the onActivityResult() method (as shown in the code below) has to be overridden to handle the permission Accepted or Denied cases for consistent UX. Also, for integrating Native Modules which use startActivityForResult, we need to pass the result to the onActivityResult method of our ReactInstanceManager instance.
    
+
    @Override
+protected void onActivityResult(int requestCode, int resultCode, Intent data) {
+    if (requestCode == OVERLAY_PERMISSION_REQ_CODE) {
+        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
+            if (!Settings.canDrawOverlays(this)) {
+                // SYSTEM_ALERT_WINDOW permission not granted
+            }
+        }
+    }
+    mReactInstanceManager.onActivityResult( this, requestCode, resultCode, data );
+}
+
    
+
    The Magic: ReactRootView
    
+
    Let's add some native code in order to start the React Native runtime and tell it to render our JS component. To do this, we're going to create an Activity that creates a ReactRootView, starts a React application inside it and sets it as the main content view.
    
+
    
+
    If you are targetting Android version <5, use the AppCompatActivity class from the com.android.support:appcompat package instead of Activity.
    
+
    
+
    public class MyReactActivity extends Activity implements DefaultHardwareBackBtnHandler {
+    private ReactRootView mReactRootView;
+    private ReactInstanceManager mReactInstanceManager;
+
+    @Override
+    protected void onCreate(Bundle savedInstanceState) {
+        super.onCreate(savedInstanceState);
+
+        mReactRootView = new ReactRootView(this);
+        mReactInstanceManager = ReactInstanceManager.builder()
+                .setApplication(getApplication())
+                .setCurrentActivity(this)
+                .setBundleAssetName("index.android.bundle")
+                .setJSMainModulePath("index")
+                .addPackage(new MainReactPackage())
+                .setUseDeveloperSupport(BuildConfig.DEBUG)
+                .setInitialLifecycleState(LifecycleState.RESUMED)
+                .build();
+        // The string here (e.g. "MyReactNativeApp") has to match
+        // the string in AppRegistry.registerComponent() in index.js
+        mReactRootView.startReactApplication(mReactInstanceManager, "MyReactNativeApp", null);
+
+        setContentView(mReactRootView);
+    }
+
+    @Override
+    public void invokeDefaultOnBackPressed() {
+        super.onBackPressed();
+    }
+}
+
    
+
    
+
    If you are using a starter kit for React Native, replace the "HelloWorld" string with the one in your index.js file (it’s the first argument to the AppRegistry.registerComponent() method).
    
+
    
+
    If you are using Android Studio, use Alt + Enter to add all missing imports in your MyReactActivity class. Be careful to use your package’s BuildConfig and not the one from the facebook package.
    
+
    We need set the theme of MyReactActivity to Theme.AppCompat.Light.NoActionBar because some React Native UI components rely on this theme.
    
+
    <activity
+  android:name=".MyReactActivity"
+  android:label="@string/app_name"
+  android:theme="@style/Theme.AppCompat.Light.NoActionBar">
+</activity>
+
    
+
    
+
    A ReactInstanceManager can be shared by multiple activities and/or fragments. You will want to make your own ReactFragment or ReactActivity and have a singleton holder that holds a ReactInstanceManager. When you need the ReactInstanceManager (e.g., to hook up the ReactInstanceManager to the lifecycle of those Activities or Fragments) use the one provided by the singleton.
    
+
    
+
    Next, we need to pass some activity lifecycle callbacks to the ReactInstanceManager and ReactRootView:
    
+
    @Override
+protected void onPause() {
+    super.onPause();
+
+    if (mReactInstanceManager != null) {
+        mReactInstanceManager.onHostPause(this);
+    }
+}
+
+@Override
+protected void onResume() {
+    super.onResume();
+
+    if (mReactInstanceManager != null) {
+        mReactInstanceManager.onHostResume(this, this);
+    }
+}
+
+@Override
+protected void onDestroy() {
+    super.onDestroy();
+
+    if (mReactInstanceManager != null) {
+        mReactInstanceManager.onHostDestroy(this);
+    }
+    if (mReactRootView != null) {
+        mReactRootView.unmountReactApplication();
+    }
+}
+
    
+
    We also need to pass back button events to React Native:
    
+
    @Override
+ public void onBackPressed() {
+    if (mReactInstanceManager != null) {
+        mReactInstanceManager.onBackPressed();
+    } else {
+        super.onBackPressed();
+    }
+}
+
    
+
    This allows JavaScript to control what happens when the user presses the hardware back button (e.g. to implement navigation). When JavaScript doesn't handle the back button press, your invokeDefaultOnBackPressed method will be called. By default this simply finishes your Activity.
    
+
    Finally, we need to hook up the dev menu. By default, this is activated by (rage) shaking the device, but this is not very useful in emulators. So we make it show when you press the hardware menu button (use Ctrl + M if you're using Android Studio emulator):
    
+
    @Override
+public boolean onKeyUp(int keyCode, KeyEvent event) {
+    if (keyCode == KeyEvent.KEYCODE_MENU && mReactInstanceManager != null) {
+        mReactInstanceManager.showDevOptionsDialog();
+        return true;
+    }
+    return super.onKeyUp(keyCode, event);
+}
+
    
+
    Now your activity is ready to run some JavaScript code.
    
+
    Test your integration
    
+
    You have now done all the basic steps to integrate React Native with your current application. Now we will start the React Native packager to build the index.bundle package and the server running on localhost to serve it.
    
+
    1. Run the packager
    
+
    To run your app, you need to first start the development server. To do this, simply run the following command in the root directory of your React Native project:
    
+
    $ yarn start
+
    
+
    2. Run the app
    
+
    Now build and run your Android app as normal.
    
+
    Once you reach your React-powered activity inside the app, it should load the JavaScript code from the development server and display:
    
+
    Screenshot
    
+
    Creating a release build in Android Studio
    
+
    You can use Android Studio to create your release builds too! It’s as easy as creating release builds of your previously-existing native Android app. There’s just one additional step, which you’ll have to do before every release build. You need to execute the following to create a React Native bundle, which will be included with your native Android app:
    
+
    $ react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/com/your-company-name/app-package-name/src/main/assets/index.android.bundle --assets-dest android/com/your-company-name/app-package-name/src/main/res/
+
    
+
    
+
    Don’t forget to replace the paths with correct ones and create the assets folder if it doesn’t exist.
    
+
    
+
    Now just create a release build of your native app from within Android Studio as usual and you should be good to go!
    
+
    
+
    Now what?
    
+
    At this point you can continue developing your app as usual. Refer to our debugging and deployment docs to learn more about working with React Native.

    InteractionManager
    InteractionManager allows long-running work to be scheduled after any interactions/animations have completed. In particular, this allows JavaScript animations to run smoothly.
    
+
    Applications can schedule tasks to run after interactions with the following:
    
+
    InteractionManager.runAfterInteractions(() => {
+  // ...long-running synchronous task...
+});
+
    
+
    Compare this to other scheduling alternatives:
    
+
      
+
    • requestAnimationFrame(): for code that animates a view over time.
      • 
+
    • setImmediate/setTimeout(): run code later, note this may delay animations.
      • 
+
    • runAfterInteractions(): run code later, without delaying active animations.
      • 
+
    
+
    The touch handling system considers one or more active touches to be an 'interaction' and will delay runAfterInteractions() callbacks until all touches have ended or been cancelled.
    
+
    InteractionManager also allows applications to register animations by creating an interaction 'handle' on animation start, and clearing it upon completion:
    
+
    var handle = InteractionManager.createInteractionHandle();
+// run animation... (`runAfterInteractions` tasks are queued)
+// later, on animation completion:
+InteractionManager.clearInteractionHandle(handle);
+// queued tasks run if all handles were cleared
+
    
+
    runAfterInteractions takes either a plain callback function, or a PromiseTask object with a gen method that returns a Promise. If a PromiseTask is supplied, then it is fully resolved (including asynchronous dependencies that also schedule more tasks via runAfterInteractions) before starting on the next task that might have been queued up synchronously earlier.
    
+
    By default, queued tasks are executed together in a loop in one setImmediate batch. If setDeadline is called with a positive number, then tasks will only be executed until the deadline (in terms of js event loop run time) approaches, at which point execution will yield via setTimeout, allowing events such as touches to start interactions and block queued tasks from executing, making apps more responsive.

    JavaScript Environment
    JavaScript Runtime
    
+
    When using React Native, you're going to be running your JavaScript code in two environments:
    
+
      
+
    • In most cases, React Native will use JavaScriptCore, the JavaScript engine that powers Safari. Note that on iOS, JavaScriptCore does not use JIT due to the absence of writable executable memory in iOS apps.
      • 
+
    • When using Chrome debugging, all JavaScript code runs within Chrome itself, communicating with native code via WebSockets. Chrome uses V8 as its JavaScript engine.
      • 
+
    
+
    While both environments are very similar, you may end up hitting some inconsistencies. We're likely going to experiment with other JavaScript engines in the future, so it's best to avoid relying on specifics of any runtime.
    
+
    JavaScript Syntax Transformers
    
+
    Syntax transformers make writing code more enjoyable by allowing you to use new JavaScript syntax without having to wait for support on all interpreters.
    
+
    React Native ships with the Babel JavaScript compiler. Check Babel documentation on its supported transformations for more details.
    
+
    A full list of React Native's enabled transformations can be found in metro-react-native-babel-preset.

    KeyboardAvoidingView
    It is a component to solve the common problem of views that need to move out of the way of the virtual keyboard. It can automatically adjust either its position or bottom padding based on the position of the keyboard.

    Example usage:
    
+
    import {KeyboardAvoidingView} from 'react-native';
+
+<KeyboardAvoidingView style={styles.container} behavior="padding" enabled>

    aspectRatio
    
+
    Aspect ratio controls the size of the undefined dimension of a node. Aspect ratio is a non-standard property only available in React Native and not CSS.
    
+
      
+
    • On a node with a set width/height aspect ratio controls the size of the unset dimension
      • 
+
    • On a node with a set flex basis aspect ratio controls the size of the node in the cross axis if unset
      • 
+
    • On a node with a measure function aspect ratio works as though the measure function measures the flex basis
      • 
+
    • On a node with flex grow/shrink aspect ratio controls the size of the node in the cross axis if unset
      • 
+
    • Aspect ratio takes min/max dimensions into account

    bottom
    
+
    bottom is the number of logical pixels to offset the bottom edge of this component.
    
+
    It works similarly to bottom in CSS, but in React Native you must use points or percentages. Ems and other units are not supported.

    When the direction is ltr, end is equivalent to right. When the direction is rtl, end is equivalent to left.
    
+
    This style takes precedence over the left and right styles.

    number, stringNo
    
+
    
+
    flex
    
+
    In React Native flex does not work the same way that it does in CSS. flex is a number rather than a string, and it works according to the Yoga library at https://github.com/facebook/yoga
    
+
    When flex is a positive number, it makes the component flexible and it will be sized proportional to its flex value. So a component with flex set to 2 will take twice the space as a component with flex set to 1.
    
+
    When flex is 0, the component is sized according to width and height and it is inflexible.
    
+
    When flex is -1, the component is normally sized according width and height. However, if there's not enough space, the component will shrink to its minWidth and minHeight.
    
+
    flexGrow, flexShrink, and flexBasis work the same as in CSS.

    flexDirection
    
+
    flexDirection controls which directions children of a container go. row goes left to right, column goes top to bottom, and you may be able to guess what the other two do. It works like flex-direction in CSS, except the default is column. See https://developer.mozilla.org/en-US/docs/Web/CSS/flex-direction for more details.

    flexWrap
    
+
    flexWrap controls whether children can wrap around after they hit the end of a flex container. It works like flex-wrap in CSS (default: nowrap). See https://developer.mozilla.org/en-US/docs/Web/CSS/flex-wrap for more details. Note it does not work anymore with alignItems: stretch (the default), so you may want to use alignItems: flex-start for example (breaking change details: https://github.com/facebook/react-native/releases/tag/v0.28.0).

+
    position
    
+
    position in React Native is similar to regular CSS, but everything is set to relative by default, so absolute positioning is always just relative to the parent.
    
+
    If you want to position a child using specific numbers of logical pixels relative to its parent, set the child to have absolute position.
    
+
    If you want to position a child relative to something that is not its parent, just don't use styles for that. Use the component tree.
    
+
    See https://github.com/facebook/yoga for more details on how position differs between React Native and CSS.

    right
    
+
    right is the number of logical pixels to offset the right edge of this component.
    
+
    It works similarly to right in CSS, but in React Native you must use points or percentages. Ems and other units are not supported.

    zIndex
    
+
    zIndex controls which components display on top of others. Normally, you don't use zIndex. Components render according to their order in the document tree, so later components draw over earlier ones. zIndex may be useful if you have animations or custom modal interfaces where you don't want this behavior.
    
+
    It works like the CSS z-index property - components with a larger zIndex will render on top. Think of the z-direction like it's pointing from the phone into your eyeball. See https://developer.mozilla.org/en-US/docs/Web/CSS/z-index for more details.
    
+
    On iOS, zIndex may require Views to be siblings of each other for it to work as expected.

    • On a node with a set width/height aspect ratio controls the size of the unset dimension
      • 
+
    • On a node with a set flex basis aspect ratio controls the size of the node in the cross axis if unset
      • 
+
    • On a node with a measure function aspect ratio works as though the measure function measures the flex basis
      •

    flex
    
+
    In React Native flex does not work the same way that it does in CSS. flex is a number rather than a string, and it works according to the Yoga library at https://github.com/facebook/yoga
    
+
    When flex is a positive number, it makes the component flexible and it will be sized proportional to its flex value. So a component with flex set to 2 will take twice the space as a component with flex set to 1.
    
+
    When flex is 0, the component is sized according to width and height and it is inflexible.
    
+
    When flex is -1, the component is normally sized according width and height. However, if there's not enough space, the component will shrink to its minWidth and minHeight.
    
+
    flexGrow, flexShrink, and flexBasis work the same as in CSS.

See https://developer.mozilla.org/en-US/docs/Web/CSS/flex-wrap for more details. Note it does not work anymore with alignItems: stretch (the default), so you may want to use alignItems: flex-start for example (breaking change details: https://github.com/facebook/react-native/releases/tag/v0.28.0).

    start
    
+
    When the direction is ltr, start is equivalent to left. When the direction is rtl, start is equivalent to right.

    This style takes precedence over the left, right, and end styles.

    top
    
+
    top is the number of logical pixels to offset the top edge of this component.
    
+
    It works similarly to top in CSS, but in React Native you must use points or percentages. Ems and other units are not supported.

    width
    
+
    width sets the width of this component.
    
+
    It works similarly to width in CSS, but in React Native you must use points or percentages. Ems and other units are not supported. See https://developer.mozilla.org/en-US/docs/Web/CSS/width for more details.

    TypeRequired
    number, stringNo
    
+
    
+
    zIndex
    
+
    zIndex controls which components display on top of others. Normally, you don't use zIndex. Components render according to their order in the document tree, so later components draw over earlier ones. zIndex may be useful if you have animations or custom modal interfaces where you don't want this behavior.
    
+
    It works like the CSS z-index property - components with a larger zIndex will render on top. Think of the z-direction like it's pointing from the phone into your eyeball. See https://developer.mozilla.org/en-US/docs/Web/CSS/z-index for more details.
    
+
    On iOS, zIndex may require Views to be siblings of each other for it to work as expected.

    Linking Libraries
    Not every app uses all the native capabilities, and including the code to support all those features would impact the binary size... But we still want to make it easy to add these features whenever you need them.
    
+
    With that in mind we exposed many of these features as independent static libraries.
    
+
    For most of the libs it will be as simple as dragging two files, sometimes a third step will be necessary, but no more than that.
    
+
    All the libraries we ship with React Native live on the Libraries folder in the root of the repository. Some of them are pure JavaScript, and you only need to require it. Other libraries also rely on some native code, in that case you'll have to add these files to your app, otherwise the app will throw an error as soon as you try to use the library.
    
+
    Here are the few steps to link your libraries that contain native code
    
+
    Automatic linking
    
+
    Step 1
    
+
    Install a library with native dependencies:
    
+
    $ npm install <library-with-native-dependencies> --save
+
    
+
    
+
    Note: --save or --save-dev flag is very important for this step. React Native will link your libs based on dependencies and devDependencies in your package.json file.
    
+
    
+
    Step 2
    
+
    Link your native dependencies:
    
+
    $ react-native link
+
    
+
    Done! All libraries with native dependencies should be successfully linked to your iOS/Android project.
    
+
    
+
    Note: If your iOS project is using CocoaPods (contains Podfile) and linked library has podspec file, then react-native link will link library using Podfile. To support non-trivial Podfiles add # Add new pods below this line comment to places where you expect pods to be added.
    
+
    
+
    Manual linking
    
+
    Step 1
    
+
    If the library has native code, there must be an .xcodeproj file inside its folder. Drag this file to your project on Xcode (usually under the Libraries group on Xcode);
    
+
    
+
    Step 2
    
+
    Click on your main project file (the one that represents the .xcodeproj) select Build Phases and drag the static library from the Products folder inside the Library you are importing to Link Binary With Libraries
    
+
    
+
    Step 3
    
+
    Not every library will need this step, what you need to consider is:
    
+
    Do I need to know the contents of the library at compile time?
    
+
    What that means is, are you using this library on the native side or only in JavaScript? If you are only using it in JavaScript, you are good to go!
    
+
    If you do need to call it from native, then we need to know the library's headers. To achieve that you have to go to your project's file, select Build Settings and search for Header Search Paths. There you should include the path to your library. (This documentation used to recommend using recursive, but this is no longer recommended, as it can cause subtle build failures, especially with CocoaPods.)

    Linking
    
+
    Linking gives you a general interface to interact with both incoming and outgoing app links.
    
+
    Basic Usage
    
+
    Handling deep links
    
+
    If your app was launched from an external url registered to your app you can access and handle it from any component you want with
    
+
    componentDidMount() {
+  Linking.getInitialURL().then((url) => {
+    if (url) {
+      console.log('Initial url is: ' + url);
+    }
+  }).catch(err => console.error('An error occurred', err));
+}
+
    
+
    
+
    For instructions on how to add support for deep linking on Android, refer to Enabling Deep Links for App Content - Add Intent Filters for Your Deep Links.
    
+
    
+
    If you wish to receive the intent in an existing instance of MainActivity, you may set the launchMode of MainActivity to singleTask in AndroidManifest.xml. See <activity> documentation for more information.
    
+
    <activity
+  android:name=".MainActivity"
+  android:launchMode="singleTask">
+
    
+
    NOTE: On iOS, you'll need to link RCTLinking to your project by following the steps described here. If you also want to listen to incoming app links during your app's execution, you'll need to add the following lines to your *AppDelegate.m:
    
+
    // iOS 9.x or newer
+#import <React/RCTLinkingManager.h>
+
+- (BOOL)application:(UIApplication *)application
+   openURL:(NSURL *)url
+   options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
+{
+  return [RCTLinkingManager application:application openURL:url options:options];
+}
+
    
+
    If you're targeting iOS 8.x or older, you can use the following code instead:
    
+
    // iOS 8.x or older
+#import <React/RCTLinkingManager.h>
+
+- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
+  sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
+{
+  return [RCTLinkingManager application:application openURL:url
+                      sourceApplication:sourceApplication annotation:annotation];
+}
+
    
+
    If your app is using Universal Links, you'll need to add the following code as well:
    
+
    - (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity
+ restorationHandler:(void (^)(NSArray * _Nullable))restorationHandler
+{
+ return [RCTLinkingManager application:application
+                  continueUserActivity:userActivity
+                    restorationHandler:restorationHandler];
+}
+
    
+
    And then on your React component you'll be able to listen to the events on Linking as follows
    
+
    componentDidMount() {
+  Linking.addEventListener('url', this._handleOpenURL);
+},
+componentWillUnmount() {
+  Linking.removeEventListener('url', this._handleOpenURL);
+},
+_handleOpenURL(event) {
+  console.log(event.url);
+}
+
    
+
    Opening external links
    
+
    To start the corresponding activity for a link (web URL, email, contact etc.), call
    
+
    Linking.openURL(url).catch((err) => console.error('An error occurred', err));
+
    
+
    If you want to check if any installed app can handle a given URL beforehand you can call
    
+
    Linking.canOpenURL(url)
+  .then((supported) => {
+    if (!supported) {
+      console.log("Can't handle url: " + url);
+    } else {
+      return Linking.openURL(url);
+    }
+  })
+  .catch((err) => console.error('An error occurred', err));
+
    
+
    Methods
    
+
+
    
+
    Reference
    
+
    Methods
    
+
    constructor()
    
+
    constructor();
+
    
+
    
+
    addEventListener()
    
+
    addEventListener(type, handler);
+
    
+
    Add a handler to Linking changes by listening to the url event type and providing the handler
    
+
    
+
    removeEventListener()
    
+
    removeEventListener(type, handler);
+
    
+
    Remove a handler by passing the url event type and the handler
    
+
    
+
    openURL()
    
+
    openURL(url);
+
    
+
    Try to open the given url with any of the installed apps.
    
+
    You can use other URLs, like a location (e.g. "geo:37.484847,-122.148386" on Android or "http://maps.apple.com/?ll=37.484847,-122.148386" on iOS), a contact, or any other URL that can be opened with the installed apps.
    
+
    The method returns a Promise object. If the user confirms the open dialog or the url automatically opens, the promise is resolved. If the user cancels the open dialog or there are no registered applications for the url, the promise is rejected.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    urlstringYesThe URL to open.
    
+
    
+
    This method will fail if the system doesn't know how to open the specified URL. If you're passing in a non-http(s) URL, it's best to check {@code canOpenURL} first.
    
+
    
+
    
+
    For web URLs, the protocol ("http://", "https://") must be set accordingly!
    
+
    
+
    
+
    canOpenURL()
    
+
    canOpenURL(url);
+
    
+
    Determine whether or not an installed app can handle a given URL.
    
+
    The method returns a Promise object. When it is determined whether or not the given URL can be handled, the promise is resolved and the first parameter is whether or not it can be opened.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    urlstringYesThe URL to open.
    
+
    
+
    For web URLs, the protocol ("http://", "https://") must be set accordingly!
    
+
    
+
    
+
    As of iOS 9, your app needs to provide the LSApplicationQueriesSchemes key inside Info.plist or canOpenURL will always return false.
    
+
    
+

    Linking
    
+
    Linking gives you a general interface to interact with both incoming and outgoing app links.
    
+
    Basic Usage
    
+
    Handling deep links
    
+
    If your app was launched from an external url registered to your app you can access and handle it from any component you want with
    
+
    componentDidMount() {
+  Linking.getInitialURL().then((url) => {
+    if (url) {
+      console.log('Initial url is: ' + url);
+    }
+  }).catch(err => console.error('An error occurred', err));
+}
+
    
+
    
+
    For instructions on how to add support for deep linking on Android, refer to Enabling Deep Links for App Content - Add Intent Filters for Your Deep Links.
    
+
    
+
    If you wish to receive the intent in an existing instance of MainActivity, you may set the launchMode of MainActivity to singleTask in AndroidManifest.xml. See <activity> documentation for more information.
    
+
    <activity
+  android:name=".MainActivity"
+  android:launchMode="singleTask">
+
    
+
    NOTE: On iOS, you'll need to link RCTLinking to your project by following the steps described here. If you also want to listen to incoming app links during your app's execution, you'll need to add the following lines to your *AppDelegate.m:
    
+
    // iOS 9.x or newer
+#import <React/RCTLinkingManager.h>
+
+- (BOOL)application:(UIApplication *)application
+   openURL:(NSURL *)url
+   options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
+{
+  return [RCTLinkingManager application:application openURL:url options:options];
+}
+
    
+
    If you're targeting iOS 8.x or older, you can use the following code instead:
    
+
    // iOS 8.x or older
+#import <React/RCTLinkingManager.h>
+
+- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
+  sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
+{
+  return [RCTLinkingManager application:application openURL:url
+                      sourceApplication:sourceApplication annotation:annotation];
+}
+
    
+
    If your app is using Universal Links, you'll need to add the following code as well:
    
+
    - (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity
+ restorationHandler:(void (^)(NSArray * _Nullable))restorationHandler
+{
+ return [RCTLinkingManager application:application
+                  continueUserActivity:userActivity
+                    restorationHandler:restorationHandler];
+}
+
    
+
    And then on your React component you'll be able to listen to the events on Linking as follows
    
+
    componentDidMount() {
+  Linking.addEventListener('url', this._handleOpenURL);
+},
+componentWillUnmount() {
+  Linking.removeEventListener('url', this._handleOpenURL);
+},
+_handleOpenURL(event) {
+  console.log(event.url);
+}
+
    
+
    Opening external links
    
+
    To start the corresponding activity for a link (web URL, email, contact etc.), call
    
+
    Linking.openURL(url).catch((err) => console.error('An error occurred', err));
+
    
+
    If you want to check if any installed app can handle a given URL beforehand you can call
    
+
    Linking.canOpenURL(url)
+  .then((supported) => {
+    if (!supported) {
+      console.log("Can't handle url: " + url);
+    } else {
+      return Linking.openURL(url);
+    }
+  })
+  .catch((err) => console.error('An error occurred', err));

+
    constructor();
+
    
+
    
+
    addEventListener()
    
+
    addEventListener(type, handler);
+
    
+
    Add a handler to Linking changes by listening to the url event type and providing the handler
    
+
    
+
    removeEventListener()
    
+
    removeEventListener(type, handler);
+
    
+
    Remove a handler by passing the url event type and the handler
    
+
    
+
    openURL()
    
+
    openURL(url);
+
    
+
    Try to open the given url with any of the installed apps.
    
+
    You can use other URLs, like a location (e.g. "geo:37.484847,-122.148386" on Android or "http://maps.apple.com/?ll=37.484847,-122.148386" on iOS), a contact, or any other URL that can be opened with the installed apps.
    
+
    The method returns a Promise object. If the user confirms the open dialog or the url automatically opens, the promise is resolved. If the user cancels the open dialog or there are no registered applications for the url, the promise is rejected.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    urlstringYesThe URL to open.
    
+
    
+
    This method will fail if the system doesn't know how to open the specified URL. If you're passing in a non-http(s) URL, it's best to check {@code canOpenURL} first.
    
+
    
+
    
+
    For web URLs, the protocol ("http://", "https://") must be set accordingly!
    
+
    
+
    
+
    canOpenURL()
    
+
    canOpenURL(url);
+
    
+
    Determine whether or not an installed app can handle a given URL.
    
+
    The method returns a Promise object. When it is determined whether or not the given URL can be handled, the promise is resolved and the first parameter is whether or not it can be opened.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    urlstringYesThe URL to open.
    
+
    
+
    For web URLs, the protocol ("http://", "https://") must be set accordingly!
    
+
    
+
    
+
    As of iOS 9, your app needs to provide the LSApplicationQueriesSchemes key inside Info.plist or canOpenURL will always return false.
    
+
    
+
    
+
    getInitialURL()
    
+
    getInitialURL();
+
    
+
    If the app launch was triggered by an app link, it will give the link url, otherwise it will give null

    ListView
    DEPRECATED - use one of the new list components, such as FlatList or SectionList for bounded memory use, fewer bugs, better performance, an easier to use API, and more features. Check out this blog post for more details.
    
+
    ListView - A core component designed for efficient display of vertically scrolling lists of changing data. The minimal API is to create a ListView.DataSource, populate it with a simple array of data blobs, and instantiate a ListView component with that data source and a renderRow callback which takes a blob from the data array and returns a renderable component.
    
+
    Minimal example:
    
+
    class MyComponent extends Component {
+  constructor() {
+    super();
+    const ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
+    this.state = {
+      dataSource: ds.cloneWithRows(['row 1', 'row 2']),
+    };
+  }
+
+  render() {
+    return (
+      <ListView
+        dataSource={this.state.dataSource}
+        renderRow={(rowData) => <Text>{rowData}</Text>}
+      />
+    );
+  }
+}
+
    
+
    ListView also supports more advanced features, including sections with sticky section headers, header and footer support, callbacks on reaching the end of the available data (onEndReached) and on the set of rows that are visible in the device viewport change (onChangeVisibleRows), and several performance optimizations.
    
+
    There are a few performance operations designed to make ListView scroll smoothly while dynamically loading potentially very large (or conceptually infinite) data sets:
    
+
      
+
    • Only re-render changed rows - the rowHasChanged function provided to the data source tells the ListView if it needs to re-render a row because the source data has changed - see ListViewDataSource for more details.
      • 
+
    • Rate-limited row rendering - By default, only one row is rendered per event-loop (customizable with the pageSize prop). This breaks up the work into smaller chunks to reduce the chance of dropping frames while rendering rows.

+
    TypeRequired
    ListViewDataSourceYes
    
+
    
+
    initialListSize
    
+
    How many rows to render on initial component mount. Use this to make it so that the first screen worth of data appears at one time instead of over the course of multiple frames.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberYes
    
+
    
+
    onEndReachedThreshold

    Threshold in pixels (virtual, not physical) for calling onEndReached.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberYes
    
+
    
+
    pageSize
    
+
    Number of rows to render per event loop. Note: if your 'rows' are actually cells, i.e. they don't span the full width of your view (as in the ListViewGridLayoutExample), you should set the pageSize to be a multiple of the number of cells per row, otherwise you're likely to see gaps at the edge of the ListView as new pages are loaded.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberYes
    
+
    
+
    renderRow
    
+
    (rowData, sectionID, rowID, highlightRow) => renderable
    
+
    Takes a data entry from the data source and its ids and should return a renderable component to be rendered as the row. By default the data is exactly what was put into the data source, but it's also possible to provide custom extractors. ListView can be notified when a row is being highlighted by calling highlightRow(sectionID, rowID). This sets a boolean value of adjacentRowHighlighted in renderSeparator, allowing you to control the separators above and below the highlighted row. The highlighted state of a row can be reset by calling highlightRow(null).

+
+
+
+
    TypeRequired
    functionYes
    
+
    
+
    renderScrollComponent
    
+
    (props) => renderable
    
+
    A function that returns the scrollable component in which the list rows are rendered. Defaults to returning a ScrollView with the given props.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionYes

+
+
+
+
+
+
    TypeRequired
    numberYes
    
+
    
+
    stickyHeaderIndices
    
+
    An array of child indices determining which children get docked to the top of the screen when scrolling. For example, passing stickyHeaderIndices={[0]} will cause the first child to be fixed to the top of the scroll view. This property is not supported in conjunction with horizontal={true}.
    
+
+
+
+
+
+
+
+
    TypeRequired
    array of numberYes
    
+
    
+
    enableEmptySections
    
+
    Flag indicating whether empty section headers should be rendered. In the future release empty section headers will be rendered by default, and the flag will be deprecated. If empty sections are not desired to be rendered their indices should be excluded from sectionID object.
    
+

+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    stickySectionHeadersEnabled
    
+
    Makes the sections headers sticky. The sticky behavior means that it will scroll with the content at the top of the section until it reaches the top of the screen, at which point it will stick to the top until it is pushed off the screen by the next section header. This property is not supported in conjunction with horizontal={true}. Only enabled by default on iOS because of typical platform standards.
    
+
+
+
+
+
+
+
+
    TypeRequired
    boolNo
    
+
    
+
    renderSectionHeader
    
+
    (sectionData, sectionID) => renderable

    renderSeparator
    
+
    (sectionID, rowID, adjacentRowHighlighted) => renderable
    
+
    If provided, a renderable component to be rendered as the separator below each row but not the last row if there is a section header below. Take a sectionID and rowID of the row above and whether its adjacent row is highlighted.

    functionNo
    
+
    
+
    onChangeVisibleRows
    
+
    (visibleRows, changedRows) => void
    
+
    Called when the set of visible rows changes. visibleRows maps { sectionID: { rowID: true }} for all the visible rows, and changedRows maps { sectionID: { rowID: true | false }} for the rows that have changed their visibility, with true indicating visible, and false indicating the view has moved out of view.

+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    removeClippedSubviews
    
+
    A performance optimization for improving scroll perf of large lists, used in conjunction with overflow: 'hidden' on the row containers. This is enabled by default.
    
+
+
+
+
+
+
+
+
    TypeRequired
    boolNo
    
+
    
+
    renderFooter
    
+
    () => renderable
    
+
    The header and footer are always rendered (if these props are provided) on every render pass. If they are expensive to re-render, wrap them in StaticContainer or other mechanism as appropriate. Footer is always at the bottom of the list, and header at the top, on every render pass. In a horizontal ListView, the header is rendered on the left and the footer on the right.

    Exports some data, e.g. for perf investigations or analytics.
    
+
    
+
    scrollTo()
    
+
    scrollTo(...args: Array)
+
    
+
    Scrolls to a given x, y offset, either immediately or with a smooth animation.
    
+
    See ScrollView#scrollTo.
    
+
    
+
    scrollToEnd()
    
+
    scrollToEnd(([options]: object));
+
    
+
    If this is a vertical ListView scrolls to the bottom. If this is a horizontal ListView scrolls to the right.
    
+
    Use scrollToEnd({animated: true}) for smooth animated scrolling, scrollToEnd({animated: false}) for immediate scrolling. If no options are passed, animated defaults to true.
    
+
    See ScrollView#scrollToEnd.
    
+
    
+
    flashScrollIndicators()
    
+
    flashScrollIndicators();
+
    
+
    Displays the scroll indicators momentarily.

    Makes the sections headers sticky. The sticky behavior means that it will scroll with the content at the top of the section until it reaches the top of the screen, at which point it will stick to the top until it is pushed off the screen by the next section header. This property is not supported in conjunction with horizontal={true}. Only enabled by default on iOS because of typical platform standards.

    ListViewDataSource
    Provides efficient data processing and access to the ListView component. A ListViewDataSource is created with functions for extracting data from the input blob, and comparing elements (with default implementations for convenience). The input blob can be as simple as an array of strings, or an object with rows nested inside section objects.
    
+
    To update the data in the datasource, use cloneWithRows (or cloneWithRowsAndSections if you care about sections). The data in the data source is immutable, so you can't modify it directly. The clone methods suck in the new data and compute a diff for each row so ListView knows whether to re-render it or not.
    
+
    In this example, a component receives data in chunks, handled by _onDataArrived, which concats the new data onto the old data and updates the data source. We use concat to create a new array - mutating this._data, e.g. with this._data.push(newRowData), would be an error. _rowHasChanged understands the shape of the row data and knows how to efficiently compare it.
    
+
    getInitialState: function() {
+  var ds = new ListView.DataSource({rowHasChanged: this._rowHasChanged});
+  return {ds};
+},
+_onDataArrived(newData) {
+  this._data = this._data.concat(newData);
+  this.setState({
+    ds: this.state.ds.cloneWithRows(this._data)
+  });
+}
+
    
+
    Methods
    
+
+
    
+
    Reference
    
+
    Methods
    
+
    constructor()
    
+
    constructor(params);
+
    
+
    You can provide custom extraction and hasChanged functions for section headers and rows. If absent, data will be extracted with the defaultGetRowData and defaultGetSectionHeaderData functions.
    
+
    The default extractor expects data of one of the following forms:
    
+
     { sectionID_1: { rowID_1: <rowData1>, ... }, ... }
+
    
+
    or
    
+
     { sectionID_1: [ <rowData1>, <rowData2>, ... ], ... }
+
    
+
    or
    
+
     [ [ <rowData1>, <rowData2>, ... ], ... ]
+
    
+
    The constructor takes in a params argument that can contain any of the following:
    
+
      
+
    • getRowData(dataBlob, sectionID, rowID);
      • 
+
    • getSectionHeaderData(dataBlob, sectionID);
      • 
+
    • rowHasChanged(prevRowData, nextRowData);
      • 
+
    • sectionHeaderHasChanged(prevSectionData, nextSectionData);
      • 
+
    
+
    
+
    cloneWithRows()
    
+
    cloneWithRows(dataBlob, rowIdentities);
+
    
+
    Clones this ListViewDataSource with the specified dataBlob and rowIdentities. The dataBlob is just an arbitrary blob of data. At construction an extractor to get the interesting information was defined (or the default was used).
    
+
    The rowIdentities is a 2D array of identifiers for rows. ie. [['a1', 'a2'], ['b1', 'b2', 'b3'], ...]. If not provided, it's assumed that the keys of the section data are the row identities.
    
+
    Note: This function does NOT clone the data in this data source. It simply passes the functions defined at construction to a new data source with the data specified. If you wish to maintain the existing data you must handle merging of old and new data separately and then pass that into this function as the dataBlob.
    
+
    
+
    cloneWithRowsAndSections()
    
+
    cloneWithRowsAndSections(dataBlob, sectionIdentities, rowIdentities);
+
    
+
    This performs the same function as the cloneWithRows function but here you also specify what your sectionIdentities are. If you don't care about sections you should safely be able to use cloneWithRows.
    
+
    sectionIdentities is an array of identifiers for sections. ie. ['s1', 's2', ...]. The identifiers should correspond to the keys or array indexes of the data you wish to include. If not provided, it's assumed that the keys of dataBlob are the section identities.
    
+
    Note: this returns a new object!
    
+
    const dataSource = ds.cloneWithRowsAndSections({
+  addresses: ['row 1', 'row 2'],
+  phone_numbers: ['data 1', 'data 2'],
+}, ['phone_numbers']);
+
    
+
    
+
    getRowCount()
    
+
    getRowCount();
+
    
+
    Returns the total number of rows in the data source.
    
+
    If you are specifying the rowIdentities or sectionIdentities, then getRowCount will return the number of rows in the filtered data source.
    
+
    
+
    getRowAndSectionCount()
    
+
    getRowAndSectionCount();
+
    
+
    Returns the total number of rows in the data source (see getRowCount for how this is calculated) plus the number of sections in the data.
    
+
    If you are specifying the rowIdentities or sectionIdentities, then getRowAndSectionCount will return the number of rows & sections in the filtered data source.
    
+
    
+
    rowShouldUpdate()
    
+
    rowShouldUpdate(sectionIndex, rowIndex);
+
    
+
    Returns if the row is dirtied and needs to be rerendered
    
+
    
+
    getRowData()
    
+
    getRowData(sectionIndex, rowIndex);
+
    
+
    Gets the data required to render the row.
    
+
    
+
    getRowIDForFlatIndex()
    
+
    getRowIDForFlatIndex(index);
+
    
+
    Gets the rowID at index provided if the dataSource arrays were flattened, or null of out of range indexes.
    
+
    
+
    getSectionIDForFlatIndex()
    
+
    getSectionIDForFlatIndex(index);
+
    
+
    Gets the sectionID at index provided if the dataSource arrays were flattened, or null for out of range indexes.
    
+
    
+
    getSectionLengths()
    
+
    getSectionLengths();
+
    
+
    Returns an array containing the number of rows in each section
    
+
    
+
    sectionHeaderShouldUpdate()
    
+
    sectionHeaderShouldUpdate(sectionIndex);
+
    
+
    Returns if the section header is dirtied and needs to be rerendered
    
+
    
+
    getSectionHeaderData()
    
+
    getSectionHeaderData(sectionIndex);
+
    
+
    Gets the data required to render the section header

    What to Expect from Maintainers
    So you have read through the contributor's guide and you're getting ready to send your first pull request. Perhaps you've found an issue in React Native and want to work with the maintainers to land a fix. Here's what you can expect to happen when you open an issue or send a pull request.
    
+
    
+
    The following is adapted from the excellent Open Source Guide from GitHub and reflects how the maintainers of React Native are encouraged to handle your contributions.
    
+
    
+
    Handling Issues
    
+
    We see dozens of new issues being created every day. In order to help maintainers focus on what is actionable, maintainers ask contributors to do a bit of work prior to opening a new issue:
    
+
      
+
    • New issues should follow the Issue Template.
      • 
+
    • Issues should provide clear, easy to follow steps alongside sample code to reproduce the issue. Ideally, provide a Snack.
      • 
+
    
+
    Issues that do not meet the above criteria can be closed immediately, with a link to the contributor's guide.
    
+
    New issue runbook
    
+
    You have gathered all the information required to open a new issue, and you are confident it meets the contributor guidelines. Once you post an issue, this is what our maintainers will consider when deciding how to move forward:
    
+
      
+
    • Is this issue a feature request?
      
+
      Some features may not be a good fit for the core React Native library. This is usually the case for *new modules that Facebook does not use in production. In this case, a maintainer will explain that this should be released to npm as a separate module, allowing users to easily pull in the module in their projects.
      
+
      Even if the feature does belong in the core library, adding it means maintaining it. A maintainer will encourage you to submit a pull request or otherwise post your request to Canny.
      
+
      An exception can be made for proposals and long-running discussions, though these should be rare. If you have been contributing to the project long enough, you will probably already have access to the React Native Core Contributors Facebook Group, where this sort of discussion is usually held.
      • 
+
    • Is this issue a request for help?
      
+
      Questions should absolutely be asked on Stack Overflow rather than GitHub. Maintainers should encourage contributors to ask on Stack Overflow, before closing the issue. Feel free to also answer some questions on Stack Overflow, you'll get rep!
      • 
+
    • Was the Issue Template used to fill out the issue? Did the author answer Yes to both questions at the top?
      
+
      If not, the maintainer will ask you to provide more information by filling out the issue template, then they will close the issue.
      • 
+
    • Is the issue a duplicate of an existing, open issue?
      
+
      A maintainer will add a comment, Duplicate of #123, which will mark the issue as a duplicate of issue #123. They will then close the issue.
      • 
+
    • Does the issue include a Snack or list of steps to reproduce the issue?
      
+
      Issues should be relatively easy to reproduce. Sometimes the issue affects a particular app but a minimal repro is not provided, perhaps a crash is seen in the logs and the author is not sure where its coming from, maybe the issue is sporadic.
      
+
      As it happens, if a maintainer cannot easily reproduce the issue, one cannot reasonably expect them to be able to work on a fix. The maintainer will let you know this is the case, and your issue will be closed.
      
+
      Exceptions can be made if multiple people appear to be affected by the issue, especially right after a new React Native release is cut.
      • 
+
    • Is the issue for an old release of React Native?
      
+
      If so, expect to be asked if the issue can be reproduced in the latest release candidate.
      • 
+
    • Can the issue be reliably reproduced?
      
+
      Transient issues or issues that only occur on a specific project but a minimum repro is not provided may be closed.
      • 
+
    • Does the issue need more information?
      
+
      Some issues need additional information in order to reproduce them. Maintainers should explain what additional information is needed, after adding the 'Needs more information' label.
      
+
      Issues with the 'Needs more information' label that have been open for more than a week without a response from the author can be closed.
      • 
+
    • Has the issue been resolved already in the comments?
      
+
      Sometimes another contributor has already provided a solution in the comments. Maintainers may close the issue in this case.
      • 
+
    
+
    
+
    Reopening a closed issue: Sometimes it's necessary to reopen an issue. For example, if an issue was closed waiting for the author, then the author replied and it turns out this is indeed a bug, maintainers can reopen the issue.
    
+
    
+
    Valid bug reports with good repro steps are some of the best issues! Maintainers should thank the author for finding the issue, then explain that React Native is a community project and ask them if they would be up for sending a fix.
    
+
    Triaging issues
    
+
    If a issue is still open after going through all of the checks above, it will move on to the triage stage. A maintainer will then do the following:
    
+
      
+
    1. Add relevant labels.
      2. 
+
    2. Leave a comment saying the issue has been triaged.
      3. 
+
    3. Tag the relevant people.
      4. 
+
    
+
    You can generally figure out who may be relevant for a given issue by looking at the CODEOWNERS file.
    
+
    Stale issues
    
+
    Issues in the "Needs more information" state may be closed after a week with no followup from the author. Issues that have had no activity in the last two months may be closed periodically. If your issue gets closed in this manner, it's nothing personal. If you strongly believe that the issue should remain open, just let us know why.
    
+
    Simply commenting that the issue still exists is not very compelling (it's rare for critical, release blocking issues to have no activity for two months!). In order to make a good case for reopening the issue, you may need to do a bit of work:
    
+
      
+
    • Can the issue be reproduced on the latest release candidate? Post a comment with the version you tested.
      • 
+
    • If so, is there any information missing from the bug report? Post a comment with all the information required by the issue template.
      • 
+
    • Is there a pull request that addressed this issue? Post a comment with the PR number so we can follow up.
      • 
+
    
+
    A couple of contributors making a good case may be all that is needed to reopen the issue.
    
+
    Handling pull requests
    
+
    The core team will be monitoring for pull requests. When we get one, we'll run some Facebook-specific integration tests on it first. From here, we'll need to get another person to sign off on the changes and then merge the pull request. For API changes we may need to fix internal uses, which could cause some delay. We'll do our best to provide updates and feedback throughout the process.
    
+
    How we prioritize pull requests
    
+
    We use the Contributors Chrome extension to help us understand who is sending a pull request. Pull requests opened by contributors that have a history of having their PRs merged are more likely to be looked at first. Aside from that, we try to go through pull requests on a chronological order.
    
+
    How we review pull requests
    
+
    Reviewing a PR can sometimes require more time from a maintainer than it took you to write the code. Maintainers need to consider all the ramifications of importing your patch into the codebase. Does it potentially introduce breaking changes? What are the performance considerations of adding a new dependency? Will the docs need to be updated as well? Does this belong in core, or would it be a better fit as a third party package?
    
+
    Once you open a pull request, this is how you can expect maintainers to review it:
    
+
      
+
    • Is the pull request missing information?
      
+
      A test plan is required! Add the labels 'Needs revision' and 'Needs response from author'. You can then follow up with a response like:
      
+
      
+
      Hey @author, thanks for sending the pull request. Can you please add all the info specified in the template? This is necessary for people to be able to understand and review your pull request.
      
+
      • 
+
    • Does the code style match the Style guide?
      
+
      If not, link to the style guide and add the label 'Needs revision'.
      • 
+
    • Does the pull request add a completely new feature we don't want to add to the core and maintain?
      
+
      Ask the author to release it a separate npm module and close the pull request.
      • 
+
    • Does the pull request do several unrelated things at the same time?
      
+
      Ask the author to split it.
      • 
+
    • Is the pull request old and need rebasing?
      
+
      Ask the author "Can you rebase please?" and add the label 'Needs response from author'.
      • 
+
    • Is a pull request waiting for a response from author?
      
+
      Pull requests like these usually have the label 'Needs response from author'. If there has been no reply in the last 30 days, close it with a response like the following:
      
+
      
+
      Thanks for making the pull request, but we are closing it due to inactivity. If you want to get your proposed changes merged, please rebase your branch with master and send a new pull request.
      
+
      • 
+
    • Is the pull request old and waiting for review?
      
+
      Review it or cc someone who might be able to review. Finding the right person to review a pull request can sometimes be tricky. A pull request may simultaneously touch iOS, Java, and JavaScript code. If a pull request has been waiting for review for a while, you can help out by looking at the blame history for the files you're touching. Is there anyone that appears to be knowledgeable in the part of the codebase the PR is touching?
      • 
+
    
+
    Closing pull requests
    
+
    Sometimes a maintainer may decide that a pull request will not be accepted. Maybe the pull request is out of scope for the project, or the idea is good but the implementation is poor. Whatever the reason, when closing a pull request maintainers should keep the conversation friendly:
    
+
      
+
    • Thank them for their contribution.
      • 
+
    • Explain why it doesn't fit into the scope of the project.
      • 
+
    • Link to relevant documentation, if you have it.
      • 
+
    • Close the request.
      • 
+
    
+
    Defusing situations
    
+
    Sometimes when a maintainer says no to a pull request or close an issue, a contributor may get upset and criticize your decision. Maintainers will take steps to defuse the situation.
    
+
    If a contributor becomes hostile or disrespectful, they will be referred to the Code of Conduct. Negative users will be blocked, and inappropriate comments will be deleted.
    
+
    Facebook GitHub Bot
    
+
    The Facebook GitHub Bot was used to allow members of the community to perform administrative actions such as labeling and closing issues. The bot is no longer necessary, as maintainers will be granted the necessary permissions to manage issues. If you are interested in maintaining the repo, please reach out to Héctor Ramos (@hramos) on GitHub.

    What to Expect from Maintainers
    So you have read through the contributor's guide and you're getting ready to send your first pull request. Perhaps you've found an issue in React Native and want to work with the maintainers to land a fix. Here's what you can expect to happen when you open an issue or send a pull request.
    
+
    
+
    The following is adapted from the excellent Open Source Guide from GitHub and reflects how the maintainers of React Native are encouraged to handle your contributions.
    
+
    
+
    Handling Issues
    
+
    We see dozens of new issues being created every day. In order to help maintainers focus on what is actionable, maintainers ask contributors to do a bit of work prior to opening a new issue:
    
+
      
+
    • New issues should follow the Issue Template.
      • 
+
    • Issues should provide clear, easy to follow steps alongside sample code to reproduce the issue. Ideally, provide a Snack.
      • 
+
    
+
    Issues that do not meet the above criteria can be closed immediately, with a link to the contributor's guide.
    
+
    New issue runbook
    
+
    You have gathered all the information required to open a new issue, and you are confident it meets the contributor guidelines. Once you post an issue, this is what our maintainers will consider when deciding how to move forward:
    
+
      
+
    • Is this issue a feature request?
      
+
      Some features may not be a good fit for the core React Native library. This is usually the case for *new modules that Facebook does not use in production. In this case, a maintainer will explain that this should be released to npm as a separate module, allowing users to easily pull in the module in their projects.
      
+
      Even if the feature does belong in the core library, adding it means maintaining it. A maintainer will encourage you to submit a pull request or otherwise post your request to Canny.
      
+
      An exception can be made for proposals and long-running discussions, though these should be rare. If you have been contributing to the project long enough, you will probably already have access to the React Native Core Contributors Facebook Group, where this sort of discussion is usually held.
      • 
+
    • Is this issue a request for help?
      
+
      Questions should absolutely be asked on Stack Overflow rather than GitHub. Maintainers should encourage contributors to ask on Stack Overflow, before closing the issue. Feel free to also answer some questions on Stack Overflow, you'll get rep!
      • 
+
    • Was the Issue Template used to fill out the issue? Did the author answer Yes to both questions at the top?
      
+
      If not, the maintainer will ask you to provide more information by filling out the issue template, then they will close the issue.
      • 
+
    • Is the issue a duplicate of an existing, open issue?
      
+
      A maintainer will add a comment, Duplicate of #123, which will mark the issue as a duplicate of issue #123. They will then close the issue.
      • 
+
    • Does the issue include a Snack or list of steps to reproduce the issue?
      
+
      Issues should be relatively easy to reproduce. Sometimes the issue affects a particular app but a minimal repro is not provided, perhaps a crash is seen in the logs and the author is not sure where its coming from, maybe the issue is sporadic.
      
+
      As it happens, if a maintainer cannot easily reproduce the issue, one cannot reasonably expect them to be able to work on a fix. The maintainer will let you know this is the case, and your issue will be closed.
      
+
      Exceptions can be made if multiple people appear to be affected by the issue, especially right after a new React Native release is cut.
      • 
+
    • Is the issue for an old release of React Native?
      
+
      If so, expect to be asked if the issue can be reproduced in the latest release candidate.
      • 
+
    • Can the issue be reliably reproduced?
      
+
      Transient issues or issues that only occur on a specific project but a minimum repro is not provided may be closed.
      • 
+
    • Does the issue need more information?
      
+
      Some issues need additional information in order to reproduce them. Maintainers should explain what additional information is needed, after adding the 'Needs more information' label.
      
+
      Issues with the 'Needs more information' label that have been open for more than a week without a response from the author can be closed.
      • 
+
    • Has the issue been resolved already in the comments?
      
+
      Sometimes another contributor has already provided a solution in the comments. Maintainers may close the issue in this case.
      • 
+
    
+
    
+
    Reopening a closed issue: Sometimes it's necessary to reopen an issue. For example, if an issue was closed waiting for the author, then the author replied and it turns out this is indeed a bug, maintainers can reopen the issue.
    
+
    
+
    Valid bug reports with good repro steps are some of the best issues! Maintainers should thank the author for finding the issue, then explain that React Native is a community project and ask them if they would be up for sending a fix.
    
+
    Triaging issues
    
+
    If a issue is still open after going through all of the checks above, it will move on to the triage stage. A maintainer will then do the following:
    
+
      
+
    1. Add relevant labels.
      2. 
+
    2. Leave a comment saying the issue has been triaged.
      3. 
+
    3. Tag the relevant people.
      4. 
+
    
+
    You can generally figure out who may be relevant for a given issue by looking at the CODEOWNERS file.
    
+
    Stale issues
    
+
    Issues in the "Needs more information" state may be closed after a week with no followup from the author. Issues that have had no activity in the last two months may be closed periodically. If your issue gets closed in this manner, it's nothing personal. If you strongly believe that the issue should remain open, just let us know why.
    
+
    Simply commenting that the issue still exists is not very compelling (it's rare for critical, release blocking issues to have no activity for two months!). In order to make a good case for reopening the issue, you may need to do a bit of work:
    
+
      
+
    • Can the issue be reproduced on the latest release candidate? Post a comment with the version you tested.
      • 
+
    • If so, is there any information missing from the bug report? Post a comment with all the information required by the issue template.
      • 
+
    • Is there a pull request that addressed this issue? Post a comment with the PR number so we can follow up.
      • 
+
    
+
    A couple of contributors making a good case may be all that is needed to reopen the issue.

    Props
    
+
    visible
    
+
    The visible prop determines whether your modal is visible.
    
+
+
+
+
+
+
+
+
    TypeRequired
    boolNo
    
+
    
+
    supportedOrientations
    
+
    The supportedOrientations prop allows the modal to be rotated to any of the specified orientations. On iOS, the modal is still restricted by what's specified in your app's Info.plist's UISupportedInterfaceOrientations field.

    Modal
    The Modal component is a simple way to present content above an enclosing view.
    
+
    
+
    Note: If you need more control over how to present modals over the rest of your app, then consider using a top-level Navigator.
    
+

    import React, {Component} from 'react';
+import {Modal, Text, TouchableHighlight, View, Alert} from 'react-native';
+
+class ModalExample extends Component {

+  };
+
+  setModalVisible(visible) {

    If you just read through this website, you should be able to build a pretty cool React Native app. But React Native isn't just a product made by one company - it's a community of thousands of developers. So if you're interested in React Native, here's some related stuff you might want to check out.
    
+
    Popular Libraries
    
+
    If you're using React Native, you probably already know about React. So I feel a bit silly mentioning this. But if you haven't, check out React - it's the best way to build a modern website.
    
+
    One common question is how to handle the "state" of your React Native application. The most popular library for this is Redux. Don't be afraid of how often Redux uses the word "reducer" - it's a pretty simple library, and there's also a nice series of videos explaining it.
    
+
    If you're looking for a library that does a specific thing, check out Awesome React Native, a curated list of components that also has demos, articles, and other stuff.
    
+
    Examples
    
+
    Try out apps from the Showcase to see what React Native is capable of! There are also some example apps on GitHub. You can run the apps on a simulator or device, and you can see the source code for these apps, which is neat.
    
+
    The folks who built the app for Facebook's F8 conference also open-sourced the code and wrote up a detailed series of tutorials. This is useful if you want a more in-depth example that's more realistic than most sample apps out there.
    
+
    Extending React Native
    
+
      
+
    • Fellow developers write and publish React Native modules to npm and open source them on GitHub.
      • 
+
    • Making modules helps grow the React Native ecosystem and community. We recommend writing modules for your use cases and sharing them on npm.
      • 
+
    • Read the guides on Native Modules (iOS, Android) and Native UI Components (iOS, Android) if you are interested in extending native functionality.
      • 
+
    • Looking for a pre-built component? Check JS.coach or Native Directory to find what the community has been creating.
      • 
+
    
+
    Development Tools
    
+
    Nuclide is the IDE that Facebook uses internally for JavaScript development. The killer feature of Nuclide is its debugging ability. It also has great inline Flow support. VS Code is another IDE that is popular with JavaScript developers.
    
+
    Ignite is a starter kit that uses Redux and a few different common UI libraries. It has a CLI to generate apps, components, and containers. If you like all of the individual tech choices, Ignite could be perfect for you.
    
+
    App Center is a service from Microsoft that makes it easy to deploy live updates to your React Native app. If you don't like going through the app store process to deploy little tweaks, and you also don't like setting up your own backend, give App Center a try.
    
+
    Expo is a development environment plus application that focuses on letting you build React Native apps in the Expo development environment, without ever touching Xcode or Android Studio. If you wish React Native was even more JavaScripty and webby, check out Expo.
    
+
    Yoga is a stand-alone layout engine that extends beyond React Native and allows product engineers to build layouts quickly for multiple platforms with a highly optimized open source layout engine designed with speed, size, and ease of use in mind.
    
+
    Bugsnag, Microsoft App Center, and Sentry all provide excellent crash and error monitoring services for React and React Native apps. These services allow you to proactively monitor crashes and issues occuring on your apps in real time so you can fix them quickly and improve user experience.
    
+
    The React Developer Tools are great for debugging React and React Native apps.

+Native UI Components · React Native

    Edit
    Native UI Components
    There are tons of native UI widgets out there ready to be used in the latest apps - some of them are part of the platform, others are available as third-party libraries, and still more might be in use in your very own portfolio. React Native has several of the most critical platform components already wrapped, like ScrollView and TextInput, but not all of them, and certainly not ones you might have written yourself for a previous app. Fortunately, it's quite easy to wrap up these existing components for seamless integration with your React Native application.
    
+
    Like the native module guide, this too is a more advanced guide that assumes you are somewhat familiar with Android SDK programming. This guide will show you how to build a native UI component, walking you through the implementation of a subset of the existing ImageView component available in the core React Native library.
    
+
    ImageView example
    
+
    For this example we are going to walk through the implementation requirements to allow the use of ImageViews in JavaScript.
    
+
    Native views are created and manipulated by extending ViewManager or more commonly SimpleViewManager . A SimpleViewManager is convenient in this case because it applies common properties such as background color, opacity, and Flexbox layout.
    
+
    These subclasses are essentially singletons - only one instance of each is created by the bridge. They vend native views to the NativeViewHierarchyManager, which delegates back to them to set and update the properties of the views as necessary. The ViewManagers are also typically the delegates for the views, sending events back to JavaScript via the bridge.
    
+
    Vending a view is simple:
    
+
      
+
    1. Create the ViewManager subclass.
      2. 
+
    2. Implement the createViewInstance method
      3. 
+
    3. Expose view property setters using @ReactProp (or @ReactPropGroup) annotation
      4. 
+
    4. Register the manager in createViewManagers of the applications package.
      5. 
+
    5. Implement the JavaScript module
      6. 
+
    
+
    1. Create the ViewManager subclass
    
+
    In this example we create view manager class ReactImageManager that extends SimpleViewManager of type ReactImageView. ReactImageView is the type of object managed by the manager, this will be the custom native view. Name returned by getName is used to reference the native view type from JavaScript.
    
+
    ...
+
+public class ReactImageManager extends SimpleViewManager<ReactImageView> {
+
+  public static final String REACT_CLASS = "RCTImageView";
+
+  @Override
+  public String getName() {
+    return REACT_CLASS;
+  }
+
    
+
    2. Implement method createViewInstance
    
+
    Views are created in the createViewInstance method, the view should initialize itself in its default state, any properties will be set via a follow up call to updateView.
    
+
      @Override
+  public ReactImageView createViewInstance(ThemedReactContext context) {
+    return new ReactImageView(context, Fresco.newDraweeControllerBuilder(), mCallerContext);
+  }
+
    
+
    3. Expose view property setters using @ReactProp (or @ReactPropGroup) annotation
    
+
    Properties that are to be reflected in JavaScript needs to be exposed as setter method annotated with @ReactProp (or @ReactPropGroup). Setter method should take view to be updated (of the current view type) as a first argument and property value as a second argument. Setter should be declared as a void method and should be public. Property type sent to JS is determined automatically based on the type of value argument of the setter. The following type of values are currently supported: boolean, int, float, double, String, Boolean, Integer, ReadableArray, ReadableMap.
    
+
    Annotation @ReactProp has one obligatory argument name of type String. Name assigned to the @ReactProp annotation linked to the setter method is used to reference the property on JS side.
    
+
    Except from name, @ReactProp annotation may take following optional arguments: defaultBoolean, defaultInt, defaultFloat. Those arguments should be of the corresponding primitive type (accordingly boolean, int, float) and the value provided will be passed to the setter method in case when the property that the setter is referencing has been removed from the component. Note that "default" values are only provided for primitive types, in case when setter is of some complex type, null will be provided as a default value in case when corresponding property gets removed.
    
+
    Setter declaration requirements for methods annotated with @ReactPropGroup are different than for @ReactProp, please refer to the @ReactPropGroup annotation class docs for more information about it.
    
+
    IMPORTANT! in ReactJS updating the property value will result in setter method call. Note that one of the ways we can update component is by removing properties that have been set before. In that case setter method will be called as well to notify view manager that property has changed. In that case "default" value will be provided (for primitive types "default" can value can be specified using defaultBoolean, defaultFloat, etc. arguments of @ReactProp annotation, for complex types setter will be called with value set to null).
    
+
      @ReactProp(name = "src")
+  public void setSrc(ReactImageView view, @Nullable ReadableArray sources) {
+    view.setSource(sources);
+  }
+
+  @ReactProp(name = "borderRadius", defaultFloat = 0f)
+  public void setBorderRadius(ReactImageView view, float borderRadius) {
+    view.setBorderRadius(borderRadius);
+  }
+
+  @ReactProp(name = ViewProps.RESIZE_MODE)
+  public void setResizeMode(ReactImageView view, @Nullable String resizeMode) {
+    view.setScaleType(ImageResizeMode.toScaleType(resizeMode));
+  }
+
    
+
    4. Register the ViewManager
    
+
    The final Java step is to register the ViewManager to the application, this happens in a similar way to Native Modules, via the applications package member function createViewManagers.
    
+
      @Override
+  public List<ViewManager> createViewManagers(
+                            ReactApplicationContext reactContext) {
+    return Arrays.<ViewManager>asList(
+      new ReactImageManager()
+    );
+  }
+
    
+
    5. Implement the JavaScript module
    
+
    The very final step is to create the JavaScript module that defines the interface layer between Java and JavaScript for the users of your new view. It is recommended for you to document the component interface in this module (e.g. using Flow, TypeScript, or plain old comments).
    
+
    // ImageView.js
+
+import {requireNativeComponent} from 'react-native';
+
+/**
+ * Composes `View`.
+ *
+ * - src: string
+ * - borderRadius: number
+ * - resizeMode: 'cover' | 'contain' | 'stretch'
+ */
+module.exports = requireNativeComponent('RCTImageView');
+
    
+
    The requireNativeComponent function takes the name of the native view. Note that if your component needs to do anything more sophisticated (e.g. custom event handling), you should wrap the native component in another React component. This is illustrated in the MyCustomView example below.
    
+
    Events
    
+
    So now we know how to expose native view components that we can control easily from JS, but how do we deal with events from the user, like pinch-zooms or panning? When a native event occurs the native code should issue an event to the JavaScript representation of the View, and the two views are linked with the value returned from the getId() method.
    
+
    class MyCustomView extends View {
+   ...
+   public void onReceiveNativeEvent() {
+      WritableMap event = Arguments.createMap();
+      event.putString("message", "MyMessage");
+      ReactContext reactContext = (ReactContext)getContext();
+      reactContext.getJSModule(RCTEventEmitter.class).receiveEvent(
+          getId(),
+          "topChange",
+          event);
+    }
+}
+
    
+
    To map the topChange event name to the onChange callback prop in JavaScript, register it by overriding the getExportedCustomBubblingEventTypeConstants method in your ViewManager:
    
+
    public class ReactImageManager extends SimpleViewManager<MyCustomView> {
+    ...
+    public Map getExportedCustomBubblingEventTypeConstants() {
+        return MapBuilder.builder()
+            .put(
+                "topChange",
+                MapBuilder.of(
+                    "phasedRegistrationNames",
+                    MapBuilder.of("bubbled", "onChange")))
+                    .build();
+    }
+}
+
    
+
    This callback is invoked with the raw event, which we typically process in the wrapper component to make a simpler API:
    
+
    // MyCustomView.js
+
+class MyCustomView extends React.Component {
+  constructor(props) {
+    super(props);
+    this._onChange = this._onChange.bind(this);
+  }
+  _onChange(event: Event) {
+    if (!this.props.onChangeMessage) {
+      return;
+    }
+    this.props.onChangeMessage(event.nativeEvent.message);
+  }
+  render() {
+    return <RCTMyCustomView {...this.props} onChange={this._onChange} />;
+  }
+}
+MyCustomView.propTypes = {
+  /**
+   * Callback that is called continuously when the user is dragging the map.
+   */
+  onChangeMessage: PropTypes.func,
+  ...
+};
+
+var RCTMyCustomView = requireNativeComponent(`RCTMyCustomView`);
+

    Native UI Components
    There are tons of native UI widgets out there ready to be used in the latest apps - some of them are part of the platform, others are available as third-party libraries, and still more might be in use in your very own portfolio. React Native has several of the most critical platform components already wrapped, like ScrollView and TextInput, but not all of them, and certainly not ones you might have written yourself for a previous app. Fortunately, it's quite easy to wrap up these existing components for seamless integration with your React Native application.
    
+
    Like the native module guide, this too is a more advanced guide that assumes you are somewhat familiar with Android SDK programming. This guide will show you how to build a native UI component, walking you through the implementation of a subset of the existing ImageView component available in the core React Native library.
    
+
    ImageView example
    
+
    For this example we are going to walk through the implementation requirements to allow the use of ImageViews in JavaScript.
    
+
    Native views are created and manipulated by extending ViewManager or more commonly SimpleViewManager . A SimpleViewManager is convenient in this case because it applies common properties such as background color, opacity, and Flexbox layout.
    
+
    These subclasses are essentially singletons - only one instance of each is created by the bridge. They vend native views to the NativeViewHierarchyManager, which delegates back to them to set and update the properties of the views as necessary. The ViewManagers are also typically the delegates for the views, sending events back to JavaScript via the bridge.
    
+
    Vending a view is simple:
    
+
      
+
    1. Create the ViewManager subclass.
      2. 
+
    2. Implement the createViewInstance method
      3. 
+
    3. Expose view property setters using @ReactProp (or @ReactPropGroup) annotation
      4. 
+
    4. Register the manager in createViewManagers of the applications package.
      5. 
+
    5. Implement the JavaScript module
      6. 
+
    
+
    1. Create the ViewManager subclass
    
+
    In this example we create view manager class ReactImageManager that extends SimpleViewManager of type ReactImageView. ReactImageView is the type of object managed by the manager, this will be the custom native view. Name returned by getName is used to reference the native view type from JavaScript.
    
+
    ...
+
+public class ReactImageManager extends SimpleViewManager<ReactImageView> {
+
+  public static final String REACT_CLASS = "RCTImageView";
+
+  @Override
+  public String getName() {
+    return REACT_CLASS;
+  }
+
    
+
    2. Implement method createViewInstance
    
+
    Views are created in the createViewInstance method, the view should initialize itself in its default state, any properties will be set via a follow up call to updateView.
    
+
      @Override
+  public ReactImageView createViewInstance(ThemedReactContext context) {
+    return new ReactImageView(context, Fresco.newDraweeControllerBuilder(), mCallerContext);
+  }
+
    
+
    3. Expose view property setters using @ReactProp (or @ReactPropGroup) annotation
    
+
    Properties that are to be reflected in JavaScript needs to be exposed as setter method annotated with @ReactProp (or @ReactPropGroup). Setter method should take view to be updated (of the current view type) as a first argument and property value as a second argument. Setter should be declared as a void method and should be public. Property type sent to JS is determined automatically based on the type of value argument of the setter. The following type of values are currently supported: boolean, int, float, double, String, Boolean, Integer, ReadableArray, ReadableMap.
    
+
    Annotation @ReactProp has one obligatory argument name of type String. Name assigned to the @ReactProp annotation linked to the setter method is used to reference the property on JS side.
    
+
    Except from name, @ReactProp annotation may take following optional arguments: defaultBoolean, defaultInt, defaultFloat. Those arguments should be of the corresponding primitive type (accordingly boolean, int, float) and the value provided will be passed to the setter method in case when the property that the setter is referencing has been removed from the component. Note that "default" values are only provided for primitive types, in case when setter is of some complex type, null will be provided as a default value in case when corresponding property gets removed.
    
+
    Setter declaration requirements for methods annotated with @ReactPropGroup are different than for @ReactProp, please refer to the @ReactPropGroup annotation class docs for more information about it.
    
+
    IMPORTANT! in ReactJS updating the property value will result in setter method call. Note that one of the ways we can update component is by removing properties that have been set before. In that case setter method will be called as well to notify view manager that property has changed. In that case "default" value will be provided (for primitive types "default" can value can be specified using defaultBoolean, defaultFloat, etc. arguments of @ReactProp annotation, for complex types setter will be called with value set to null).
    
+
      @ReactProp(name = "src")
+  public void setSrc(ReactImageView view, @Nullable ReadableArray sources) {
+    view.setSource(sources);
+  }
+
+  @ReactProp(name = "borderRadius", defaultFloat = 0f)
+  public void setBorderRadius(ReactImageView view, float borderRadius) {
+    view.setBorderRadius(borderRadius);
+  }
+
+  @ReactProp(name = ViewProps.RESIZE_MODE)
+  public void setResizeMode(ReactImageView view, @Nullable String resizeMode) {
+    view.setScaleType(ImageResizeMode.toScaleType(resizeMode));
+  }
+
    
+
    4. Register the ViewManager
    
+
    The final Java step is to register the ViewManager to the application, this happens in a similar way to Native Modules, via the applications package member function createViewManagers.
    
+
      @Override
+  public List<ViewManager> createViewManagers(
+                            ReactApplicationContext reactContext) {
+    return Arrays.<ViewManager>asList(
+      new ReactImageManager()
+    );
+  }
+
    
+
    5. Implement the JavaScript module
    
+
    The very final step is to create the JavaScript module that defines the interface layer between Java and JavaScript for the users of your new view. It is recommended for you to document the component interface in this module (e.g. using Flow, TypeScript, or plain old comments).
    
+
    // ImageView.js
+
+import {requireNativeComponent} from 'react-native';
+
+/**
+ * Composes `View`.
+ *
+ * - src: string
+ * - borderRadius: number
+ * - resizeMode: 'cover' | 'contain' | 'stretch'
+ */
+module.exports = requireNativeComponent('RCTImageView');
+
    
+
    The requireNativeComponent function takes the name of the native view. Note that if your component needs to do anything more sophisticated (e.g. custom event handling), you should wrap the native component in another React component. This is illustrated in the MyCustomView example below.
    
+

+   ...
+   public void onReceiveNativeEvent() {
+      WritableMap event = Arguments.createMap();
+      event.putString("message", "MyMessage");
+      ReactContext reactContext = (ReactContext)getContext();
+      reactContext.getJSModule(RCTEventEmitter.class).receiveEvent(
+          getId(),
+          "topChange",
+          event);
+    }
+}
+
    
+
    To map the topChange event name to the onChange callback prop in JavaScript, register it by overriding the getExportedCustomBubblingEventTypeConstants method in your ViewManager:
    
+
    public class ReactImageManager extends SimpleViewManager<MyCustomView> {
+    ...
+    public Map getExportedCustomBubblingEventTypeConstants() {
+        return MapBuilder.builder()
+            .put(
+                "topChange",
+                MapBuilder.of(
+                    "phasedRegistrationNames",
+                    MapBuilder.of("bubbled", "onChange")))
+                    .build();
+    }
+}
+
    
+
    This callback is invoked with the raw event, which we typically process in the wrapper component to make a simpler API:

+  _onChange(event: Event) {
+    if (!this.props.onChangeMessage) {
+      return;
+    }
+    this.props.onChangeMessage(event.nativeEvent.message);
+  }
+  render() {
+    return <RCTMyCustomView {...this.props} onChange={this._onChange} />;
+  }
+}
+MyCustomView.propTypes = {
+  /**
+   * Callback that is called continuously when the user is dragging the map.

    Native UI Components
    There are tons of native UI widgets out there ready to be used in the latest apps - some of them are part of the platform, others are available as third-party libraries, and still more might be in use in your very own portfolio. React Native has several of the most critical platform components already wrapped, like ScrollView and TextInput, but not all of them, and certainly not ones you might have written yourself for a previous app. Fortunately, it's quite easy to wrap up these existing components for seamless integration with your React Native application.
    
+
    Like the native module guide, this too is a more advanced guide that assumes you are somewhat familiar with iOS programming. This guide will show you how to build a native UI component, walking you through the implementation of a subset of the existing MapView component available in the core React Native library.
    
+
    iOS MapView example
    
+
    Let's say we want to add an interactive Map to our app - might as well use MKMapView, we just need to make it usable from JavaScript.
    
+
    Native views are created and manipulated by subclasses of RCTViewManager. These subclasses are similar in function to view controllers, but are essentially singletons - only one instance of each is created by the bridge. They expose native views to the RCTUIManager, which delegates back to them to set and update the properties of the views as necessary. The RCTViewManagers are also typically the delegates for the views, sending events back to JavaScript via the bridge.
    
+
    Exposing a view is simple:
    
+
      
+
    • Subclass RCTViewManager to create a manager for your component.
      • 
+
    • Add the RCT_EXPORT_MODULE() marker macro.
      • 
+
    • Implement the -(UIView *)view method.
      • 
+
    
+
    // RNTMapManager.m
+#import <MapKit/MapKit.h>
+
+#import <React/RCTViewManager.h>
+
+@interface RNTMapManager : RCTViewManager
+@end
+
+@implementation RNTMapManager
+
+RCT_EXPORT_MODULE(RNTMap)
+
+- (UIView *)view
+{
+  return [[MKMapView alloc] init];
+}
+
+@end
+
    
+
    Note: Do not attempt to set the frame or backgroundColor properties on the UIView instance that you expose through the -view method. React Native will overwrite the values set by your custom class in order to match your JavaScript component's layout props. If you need this granularity of control it might be better to wrap the UIView instance you want to style in another UIView and return the wrapper UIView instead. See Issue 2948 for more context.
    
+
    
+
    In the example above, we prefixed our class name with RNT. Prefixes are used to avoid name collisions with other frameworks. Apple frameworks use two-letter prefixes, and React Native uses RCT as a prefix. In order to avoid name collisions, we recommend using a three-letter prefix other than RCT in your own classes.
    
+
    
+
    Then you just need a little bit of JavaScript to make this a usable React component:
    
+
    // MapView.js
+
+import { requireNativeComponent } from 'react-native';
+
+// requireNativeComponent automatically resolves 'RNTMap' to 'RNTMapManager'
+module.exports = requireNativeComponent('RNTMap', null);
+
+// MyApp.js
+
+import MapView from './MapView.js';
+
+...
+
+render() {
+  return <MapView style={{ flex: 1 }} />;
+}
+
    
+
    Make sure to use RNTMap here. We want to require the manager here, which will expose the view of our manager for use in Javascript.
    
+
    Note: When rendering, don't forget to stretch the view, otherwise you'll be staring at a blank screen.
    
+
      render() {
+    return <MapView style={{flex: 1}} />;
+  }
+
    
+
    This is now a fully-functioning native map view component in JavaScript, complete with pinch-zoom and other native gesture support. We can't really control it from JavaScript yet, though :(
    
+
    Properties
    
+
    The first thing we can do to make this component more usable is to bridge over some native properties. Let's say we want to be able to disable zooming and specify the visible region. Disabling zoom is a simple boolean, so we add this one line:
    
+
    // RNTMapManager.m
+RCT_EXPORT_VIEW_PROPERTY(zoomEnabled, BOOL)
+
    
+
    Note that we explicitly specify the type as BOOL - React Native uses RCTConvert under the hood to convert all sorts of different data types when talking over the bridge, and bad values will show convenient "RedBox" errors to let you know there is an issue ASAP. When things are straightforward like this, the whole implementation is taken care of for you by this macro.
    
+
    Now to actually disable zooming, we set the property in JS:
    
+
    // MyApp.js
+<MapView zoomEnabled={false} style={{flex: 1}} />
+
    
+
    To document the properties (and which values they accept) of our MapView component we'll add a wrapper component and document the interface with React PropTypes:
    
+
    // MapView.js
+import PropTypes from 'prop-types';
+import React from 'react';
+import {requireNativeComponent} from 'react-native';
+
+class MapView extends React.Component {
+  render() {
+    return <RNTMap {...this.props} />;
+  }
+}
+
+MapView.propTypes = {
+  /**
+   * A Boolean value that determines whether the user may use pinch
+   * gestures to zoom in and out of the map.
+   */
+  zoomEnabled: PropTypes.bool,
+};
+
+var RNTMap = requireNativeComponent('RNTMap', MapView);
+
+module.exports = MapView;
+
    
+
    Now we have a nicely documented wrapper component that is easy to work with. Note that we changed requireNativeComponent's second argument from null to the new MapView wrapper component. This allows the infrastructure to verify that the propTypes match the native props in order to reduce the chances of mismatches between the Objective-C and JavaScript code.
    
+
    Next, let's add the more complex region prop. We start by adding the native code:
    
+
    // RNTMapManager.m
+RCT_CUSTOM_VIEW_PROPERTY(region, MKCoordinateRegion, MKMapView)
+{
+  [view setRegion:json ? [RCTConvert MKCoordinateRegion:json] : defaultView.region animated:YES];
+}
+
    
+
    Ok, this is more complicated than the simple BOOL case we had before. Now we have a MKCoordinateRegion type that needs a conversion function, and we have custom code so that the view will animate when we set the region from JS. Within the function body that we provide, json refers to the raw value that has been passed from JS. There is also a view variable which gives us access to the manager's view instance, and a defaultView that we use to reset the property back to the default value if JS sends us a null sentinel.
    
+
    You could write any conversion function you want for your view - here is the implementation for MKCoordinateRegion via a category on RCTConvert. It uses an already existing category of ReactNative RCTConvert+CoreLocation:
    
+
    // RNTMapManager.m
+
+#import "RCTConvert+Mapkit.m"
+
+// RCTConvert+Mapkit.h
+
+#import <MapKit/MapKit.h>
+#import <React/RCTConvert.h>
+#import <CoreLocation/CoreLocation.h>
+#import <React/RCTConvert+CoreLocation.h>
+
+@interface RCTConvert (Mapkit)
+
++ (MKCoordinateSpan)MKCoordinateSpan:(id)json;
++ (MKCoordinateRegion)MKCoordinateRegion:(id)json;
+
+@end
+
+@implementation RCTConvert(MapKit)
+
++ (MKCoordinateSpan)MKCoordinateSpan:(id)json
+{
+  json = [self NSDictionary:json];
+  return (MKCoordinateSpan){
+    [self CLLocationDegrees:json[@"latitudeDelta"]],
+    [self CLLocationDegrees:json[@"longitudeDelta"]]
+  };
+}
+
++ (MKCoordinateRegion)MKCoordinateRegion:(id)json
+{
+  return (MKCoordinateRegion){
+    [self CLLocationCoordinate2D:json],
+    [self MKCoordinateSpan:json]
+  };
+}
+
+@end
+
    
+
    These conversion functions are designed to safely process any JSON that the JS might throw at them by displaying "RedBox" errors and returning standard initialization values when missing keys or other developer errors are encountered.
    
+
    To finish up support for the region prop, we need to document it in propTypes (or we'll get an error that the native prop is undocumented), then we can set it just like any other prop:
    
+
    // MapView.js
+
+MapView.propTypes = {
+  /**
+   * A Boolean value that determines whether the user may use pinch
+   * gestures to zoom in and out of the map.
+   */
+  zoomEnabled: PropTypes.bool,
+
+  /**
+   * The region to be displayed by the map.
+   *
+   * The region is defined by the center coordinates and the span of
+   * coordinates to display.
+   */
+  region: PropTypes.shape({
+    /**
+     * Coordinates for the center of the map.
+     */
+    latitude: PropTypes.number.isRequired,
+    longitude: PropTypes.number.isRequired,
+
+    /**
+     * Distance between the minimum and the maximum latitude/longitude
+     * to be displayed.
+     */
+    latitudeDelta: PropTypes.number.isRequired,
+    longitudeDelta: PropTypes.number.isRequired,
+  }),
+};
+
+// MyApp.js
+
+render() {
+  var region = {
+    latitude: 37.48,
+    longitude: -122.16,
+    latitudeDelta: 0.1,
+    longitudeDelta: 0.1,
+  };
+  return (
+    <MapView
+      region={region}
+      zoomEnabled={false}
+      style={{ flex: 1 }}
+    />
+  );
+}
+
    
+
    Here you can see that the shape of the region is explicit in the JS documentation - ideally we could codegen some of this stuff, but that's not happening yet.
    
+
    Sometimes your native component will have some special properties that you don't want to be part of the API for the associated React component. For example, Switch has a custom onChange handler for the raw native event, and exposes an onValueChange handler property that is invoked with just the boolean value rather than the raw event. Since you don't want these native only properties to be part of the API, you don't want to put them in propTypes, but if you don't you'll get an error. The solution is simply to add them to the nativeOnly option, e.g.
    
+
    var RCTSwitch = requireNativeComponent('RCTSwitch', Switch, {
+  nativeOnly: {onChange: true},
+});
+
    
+
    Events
    
+
    So now we have a native map component that we can control easily from JS, but how do we deal with events from the user, like pinch-zooms or panning to change the visible region?
    
+
    Until now we've just returned a MKMapView instance from our manager's -(UIView *)view method. We can't add new properties to MKMapView so we have to create a new subclass from MKMapView which we use for our View. We can then add a onRegionChange callback on this subclass:
    
+
    // RNTMapView.h
+
+#import <MapKit/MapKit.h>
+
+#import <React/RCTComponent.h>
+
+@interface RNTMapView: MKMapView
+
+@property (nonatomic, copy) RCTBubblingEventBlock onRegionChange;
+
+@end
+
+// RNTMapView.m
+
+#import "RNTMapView.h"
+
+@implementation RNTMapView
+
+@end
+
    
+
    Note that all RCTBubblingEventBlock must be prefixed with on. Next, declare an event handler property on RNTMapManager, make it a delegate for all the views it exposes, and forward events to JS by calling the event handler block from the native view.
    
+
    // RNTMapManager.m
+
+#import <MapKit/MapKit.h>
+#import <React/RCTViewManager.h>
+
+#import "RNTMapView.h"
+#import "RCTConvert+Mapkit.m"
+
+@interface RNTMapManager : RCTViewManager <MKMapViewDelegate>
+@end
+
+@implementation RNTMapManager
+
+RCT_EXPORT_MODULE()
+
+RCT_EXPORT_VIEW_PROPERTY(zoomEnabled, BOOL)
+RCT_EXPORT_VIEW_PROPERTY(onRegionChange, RCTBubblingEventBlock)
+
+RCT_CUSTOM_VIEW_PROPERTY(region, MKCoordinateRegion, MKMapView)
+{
+    [view setRegion:json ? [RCTConvert MKCoordinateRegion:json] : defaultView.region animated:YES];
+}
+
+- (UIView *)view
+{
+  RNTMapView *map = [RNTMapView new];
+  map.delegate = self;
+  return map;
+}
+
+#pragma mark MKMapViewDelegate
+
+- (void)mapView:(RNTMapView *)mapView regionDidChangeAnimated:(BOOL)animated
+{
+  if (!mapView.onRegionChange) {
+    return;
+  }
+
+  MKCoordinateRegion region = mapView.region;
+  mapView.onRegionChange(@{
+    @"region": @{
+      @"latitude": @(region.center.latitude),
+      @"longitude": @(region.center.longitude),
+      @"latitudeDelta": @(region.span.latitudeDelta),
+      @"longitudeDelta": @(region.span.longitudeDelta),
+    }
+  });
+}
+@end
+
    
+
    In the delegate method -mapView:regionDidChangeAnimated: the event handler block is called on the corresponding view with the region data. Calling the onRegionChange event handler block results in calling the same callback prop in JavaScript. This callback is invoked with the raw event, which we typically process in the wrapper component to make a simpler API:
    
+
    // MapView.js
+
+class MapView extends React.Component {
+  _onRegionChange = (event) => {
+    if (!this.props.onRegionChange) {
+      return;
+    }
+
+    // process raw event...
+    this.props.onRegionChange(event.nativeEvent);
+  }
+  render() {
+    return (
+      <RNTMap
+        {...this.props}
+        onRegionChange={this._onRegionChange}
+      />
+    );
+  }
+}
+MapView.propTypes = {
+  /**
+   * Callback that is called continuously when the user is dragging the map.
+   */
+  onRegionChange: PropTypes.func,
+  ...
+};
+
+// MyApp.js
+
+class MyApp extends React.Component {
+  onRegionChange(event) {
+    // Do stuff with event.region.latitude, etc.
+  }
+
+  render() {
+    var region = {
+      latitude: 37.48,
+      longitude: -122.16,
+      latitudeDelta: 0.1,
+      longitudeDelta: 0.1,
+    };
+    return (
+      <MapView
+        region={region}
+        zoomEnabled={false}
+        onRegionChange={this.onRegionChange}
+      />
+    );
+  }  
+}
+
    
+
    Styles
    
+
    Since all our native react views are subclasses of UIView, most style attributes will work like you would expect out of the box. Some components will want a default style, however, for example UIDatePicker which is a fixed size. This default style is important for the layout algorithm to work as expected, but we also want to be able to override the default style when using the component. DatePickerIOS does this by wrapping the native component in an extra view, which has flexible styling, and using a fixed style (which is generated with constants passed in from native) on the inner native component:
    
+
    // DatePickerIOS.ios.js
+
+import { UIManager } from 'react-native';
+var RCTDatePickerIOSConsts = UIManager.RCTDatePicker.Constants;
+...
+  render: function() {
+    return (
+      <View style={this.props.style}>
+        <RCTDatePickerIOS
+          ref={DATEPICKER}
+          style={styles.rkDatePickerIOS}
+          ...
+        />
+      </View>
+    );
+  }
+});
+
+var styles = StyleSheet.create({
+  rkDatePickerIOS: {
+    height: RCTDatePickerIOSConsts.ComponentHeight,
+    width: RCTDatePickerIOSConsts.ComponentWidth,
+  },
+});
+
    
+
    The RCTDatePickerIOSConsts constants are exported from native by grabbing the actual frame of the native component like so:
    
+
    // RCTDatePickerManager.m
+
+- (NSDictionary *)constantsToExport
+{
+  UIDatePicker *dp = [[UIDatePicker alloc] init];
+  [dp layoutIfNeeded];
+
+  return @{
+    @"ComponentHeight": @(CGRectGetHeight(dp.frame)),
+    @"ComponentWidth": @(CGRectGetWidth(dp.frame)),
+    @"DatePickerModes": @{
+      @"time": @(UIDatePickerModeTime),
+      @"date": @(UIDatePickerModeDate),
+      @"datetime": @(UIDatePickerModeDateAndTime),
+    }
+  };
+}
+
    
+
    This guide covered many of the aspects of bridging over custom native components, but there is even more you might need to consider, such as custom hooks for inserting and laying out subviews. If you want to go even deeper, check out the source code of some of the implemented components.

    Native UI Components
    There are tons of native UI widgets out there ready to be used in the latest apps - some of them are part of the platform, others are available as third-party libraries, and still more might be in use in your very own portfolio. React Native has several of the most critical platform components already wrapped, like ScrollView and TextInput, but not all of them, and certainly not ones you might have written yourself for a previous app. Fortunately, it's quite easy to wrap up these existing components for seamless integration with your React Native application.
    
+
    Like the native module guide, this too is a more advanced guide that assumes you are somewhat familiar with iOS programming. This guide will show you how to build a native UI component, walking you through the implementation of a subset of the existing MapView component available in the core React Native library.
    
+
    iOS MapView example
    
+
    Let's say we want to add an interactive Map to our app - might as well use MKMapView, we just need to make it usable from JavaScript.
    
+
    Native views are created and manipulated by subclasses of RCTViewManager. These subclasses are similar in function to view controllers, but are essentially singletons - only one instance of each is created by the bridge. They expose native views to the RCTUIManager, which delegates back to them to set and update the properties of the views as necessary. The RCTViewManagers are also typically the delegates for the views, sending events back to JavaScript via the bridge.
    
+
    Exposing a view is simple:
    
+
      
+
    • Subclass RCTViewManager to create a manager for your component.
      • 
+
    • Add the RCT_EXPORT_MODULE() marker macro.
      • 
+
    • Implement the -(UIView *)view method.
      • 
+
    
+
    // RNTMapManager.m
+#import <MapKit/MapKit.h>
+
+#import <React/RCTViewManager.h>
+
+@interface RNTMapManager : RCTViewManager
+@end
+
+@implementation RNTMapManager
+
+RCT_EXPORT_MODULE(RNTMap)
+
+- (UIView *)view
+{
+  return [[MKMapView alloc] init];
+}
+
+@end
+
    
+
    Note: Do not attempt to set the frame or backgroundColor properties on the UIView instance that you expose through the -view method. React Native will overwrite the values set by your custom class in order to match your JavaScript component's layout props. If you need this granularity of control it might be better to wrap the UIView instance you want to style in another UIView and return the wrapper UIView instead. See Issue 2948 for more context.
    
+
    
+
    In the example above, we prefixed our class name with RNT. Prefixes are used to avoid name collisions with other frameworks. Apple frameworks use two-letter prefixes, and React Native uses RCT as a prefix. In order to avoid name collisions, we recommend using a three-letter prefix other than RCT in your own classes.
    
+
    
+
    Then you just need a little bit of JavaScript to make this a usable React component:
    
+
    // MapView.js
+
+import { requireNativeComponent } from 'react-native';
+
+// requireNativeComponent automatically resolves 'RNTMap' to 'RNTMapManager'
+module.exports = requireNativeComponent('RNTMap', null);
+
+// MyApp.js
+
+import MapView from './MapView.js';
+
+...
+
+render() {
+  return <MapView style={{ flex: 1 }} />;
+}
+
    
+
    Make sure to use RNTMap here. We want to require the manager here, which will expose the view of our manager for use in Javascript.
    
+
    Note: When rendering, don't forget to stretch the view, otherwise you'll be staring at a blank screen.
    
+
      render() {
+    return <MapView style={{flex: 1}} />;
+  }
+
    
+
    This is now a fully-functioning native map view component in JavaScript, complete with pinch-zoom and other native gesture support. We can't really control it from JavaScript yet, though :(
    
+
    Properties
    
+
    The first thing we can do to make this component more usable is to bridge over some native properties. Let's say we want to be able to disable zooming and specify the visible region. Disabling zoom is a simple boolean, so we add this one line:
    
+
    // RNTMapManager.m
+RCT_EXPORT_VIEW_PROPERTY(zoomEnabled, BOOL)
+
    
+
    Note that we explicitly specify the type as BOOL - React Native uses RCTConvert under the hood to convert all sorts of different data types when talking over the bridge, and bad values will show convenient "RedBox" errors to let you know there is an issue ASAP. When things are straightforward like this, the whole implementation is taken care of for you by this macro.
    
+
    Now to actually disable zooming, we set the property in JS:
    
+
    // MyApp.js
+<MapView zoomEnabled={false} style={{flex: 1}} />
+
    
+
    To document the properties (and which values they accept) of our MapView component we'll add a wrapper component and document the interface with React PropTypes:
    
+
    // MapView.js
+import PropTypes from 'prop-types';
+import React from 'react';
+import {requireNativeComponent} from 'react-native';
+
+class MapView extends React.Component {
+  render() {
+    return <RNTMap {...this.props} />;
+  }
+}
+
+MapView.propTypes = {
+  /**
+   * A Boolean value that determines whether the user may use pinch
+   * gestures to zoom in and out of the map.
+   */
+  zoomEnabled: PropTypes.bool,
+};
+
+var RNTMap = requireNativeComponent('RNTMap', MapView);
+
+module.exports = MapView;
+
    
+
    Now we have a nicely documented wrapper component that is easy to work with. Note that we changed requireNativeComponent's second argument from null to the new MapView wrapper component. This allows the infrastructure to verify that the propTypes match the native props in order to reduce the chances of mismatches between the Objective-C and JavaScript code.
    
+
    Next, let's add the more complex region prop. We start by adding the native code:
    
+
    // RNTMapManager.m
+RCT_CUSTOM_VIEW_PROPERTY(region, MKCoordinateRegion, MKMapView)
+{
+  [view setRegion:json ? [RCTConvert MKCoordinateRegion:json] : defaultView.region animated:YES];
+}
+
    
+
    Ok, this is more complicated than the simple BOOL case we had before. Now we have a MKCoordinateRegion type that needs a conversion function, and we have custom code so that the view will animate when we set the region from JS. Within the function body that we provide, json refers to the raw value that has been passed from JS. There is also a view variable which gives us access to the manager's view instance, and a defaultView that we use to reset the property back to the default value if JS sends us a null sentinel.
    
+
    You could write any conversion function you want for your view - here is the implementation for MKCoordinateRegion via a category on RCTConvert. It uses an already existing category of ReactNative RCTConvert+CoreLocation:
    
+
    // RNTMapManager.m
+
+#import "RCTConvert+Mapkit.m"
+
+// RCTConvert+Mapkit.h
+
+#import <MapKit/MapKit.h>
+#import <React/RCTConvert.h>
+#import <CoreLocation/CoreLocation.h>
+#import <React/RCTConvert+CoreLocation.h>
+
+@interface RCTConvert (Mapkit)
+
++ (MKCoordinateSpan)MKCoordinateSpan:(id)json;
++ (MKCoordinateRegion)MKCoordinateRegion:(id)json;
+
+@end
+
+@implementation RCTConvert(MapKit)
+
++ (MKCoordinateSpan)MKCoordinateSpan:(id)json
+{
+  json = [self NSDictionary:json];
+  return (MKCoordinateSpan){
+    [self CLLocationDegrees:json[@"latitudeDelta"]],
+    [self CLLocationDegrees:json[@"longitudeDelta"]]
+  };
+}
+
++ (MKCoordinateRegion)MKCoordinateRegion:(id)json
+{
+  return (MKCoordinateRegion){
+    [self CLLocationCoordinate2D:json],
+    [self MKCoordinateSpan:json]
+  };
+}
+
+@end
+
    
+
    These conversion functions are designed to safely process any JSON that the JS might throw at them by displaying "RedBox" errors and returning standard initialization values when missing keys or other developer errors are encountered.
    
+
    To finish up support for the region prop, we need to document it in propTypes (or we'll get an error that the native prop is undocumented), then we can set it just like any other prop:
    
+
    // MapView.js
+
+MapView.propTypes = {
+  /**
+   * A Boolean value that determines whether the user may use pinch
+   * gestures to zoom in and out of the map.
+   */
+  zoomEnabled: PropTypes.bool,
+
+  /**
+   * The region to be displayed by the map.
+   *
+   * The region is defined by the center coordinates and the span of
+   * coordinates to display.
+   */
+  region: PropTypes.shape({
+    /**
+     * Coordinates for the center of the map.
+     */
+    latitude: PropTypes.number.isRequired,
+    longitude: PropTypes.number.isRequired,
+
+    /**
+     * Distance between the minimum and the maximum latitude/longitude
+     * to be displayed.
+     */
+    latitudeDelta: PropTypes.number.isRequired,
+    longitudeDelta: PropTypes.number.isRequired,
+  }),
+};
+
+// MyApp.js
+
+render() {
+  var region = {
+    latitude: 37.48,
+    longitude: -122.16,
+    latitudeDelta: 0.1,
+    longitudeDelta: 0.1,
+  };
+  return (
+    <MapView
+      region={region}
+      zoomEnabled={false}
+      style={{ flex: 1 }}
+    />
+  );
+}
+
    
+
    Here you can see that the shape of the region is explicit in the JS documentation - ideally we could codegen some of this stuff, but that's not happening yet.
    
+
    Sometimes your native component will have some special properties that you don't want to be part of the API for the associated React component. For example, Switch has a custom onChange handler for the raw native event, and exposes an onValueChange handler property that is invoked with just the boolean value rather than the raw event. Since you don't want these native only properties to be part of the API, you don't want to put them in propTypes, but if you don't you'll get an error. The solution is simply to add them to the nativeOnly option, e.g.
    
+
    var RCTSwitch = requireNativeComponent('RCTSwitch', Switch, {
+  nativeOnly: {onChange: true},
+});
+
    
+
    Events
    
+
    So now we have a native map component that we can control easily from JS, but how do we deal with events from the user, like pinch-zooms or panning to change the visible region?
    
+
    Until now we've just returned a MKMapView instance from our manager's -(UIView *)view method. We can't add new properties to MKMapView so we have to create a new subclass from MKMapView which we use for our View. We can then add a onRegionChange callback on this subclass:
    
+
    // RNTMapView.h
+
+#import <MapKit/MapKit.h>
+
+#import <React/RCTComponent.h>
+
+@interface RNTMapView: MKMapView
+
+@property (nonatomic, copy) RCTBubblingEventBlock onRegionChange;
+
+@end
+
+// RNTMapView.m
+
+#import "RNTMapView.h"
+
+@implementation RNTMapView
+
+@end
+
    
+
    Note that all RCTBubblingEventBlock must be prefixed with on. Next, declare an event handler property on RNTMapManager, make it a delegate for all the views it exposes, and forward events to JS by calling the event handler block from the native view.
    
+
    // RNTMapManager.m
+
+#import <MapKit/MapKit.h>
+#import <React/RCTViewManager.h>
+
+#import "RNTMapView.h"
+#import "RCTConvert+Mapkit.m"
+
+@interface RNTMapManager : RCTViewManager <MKMapViewDelegate>
+@end
+
+@implementation RNTMapManager
+
+RCT_EXPORT_MODULE()
+
+RCT_EXPORT_VIEW_PROPERTY(zoomEnabled, BOOL)
+RCT_EXPORT_VIEW_PROPERTY(onRegionChange, RCTBubblingEventBlock)
+
+RCT_CUSTOM_VIEW_PROPERTY(region, MKCoordinateRegion, MKMapView)
+{
+    [view setRegion:json ? [RCTConvert MKCoordinateRegion:json] : defaultView.region animated:YES];
+}
+
+- (UIView *)view
+{
+  RNTMapView *map = [RNTMapView new];
+  map.delegate = self;
+  return map;
+}
+
+#pragma mark MKMapViewDelegate
+
+- (void)mapView:(RNTMapView *)mapView regionDidChangeAnimated:(BOOL)animated
+{
+  if (!mapView.onRegionChange) {
+    return;
+  }
+
+  MKCoordinateRegion region = mapView.region;
+  mapView.onRegionChange(@{
+    @"region": @{
+      @"latitude": @(region.center.latitude),
+      @"longitude": @(region.center.longitude),
+      @"latitudeDelta": @(region.span.latitudeDelta),
+      @"longitudeDelta": @(region.span.longitudeDelta),
+    }
+  });
+}
+@end
+
    
+
    In the delegate method -mapView:regionDidChangeAnimated: the event handler block is called on the corresponding view with the region data. Calling the onRegionChange event handler block results in calling the same callback prop in JavaScript. This callback is invoked with the raw event, which we typically process in the wrapper component to make a simpler API:
    
+
    // MapView.js
+
+class MapView extends React.Component {
+  _onRegionChange = (event) => {
+    if (!this.props.onRegionChange) {
+      return;
+    }
+
+    // process raw event...
+    this.props.onRegionChange(event.nativeEvent);
+  }
+  render() {
+    return (
+      <RNTMap
+        {...this.props}
+        onRegionChange={this._onRegionChange}
+      />
+    );
+  }
+}
+MapView.propTypes = {
+  /**
+   * Callback that is called continuously when the user is dragging the map.
+   */
+  onRegionChange: PropTypes.func,
+  ...
+};
+
+// MyApp.js
+
+class MyApp extends React.Component {
+  onRegionChange(event) {
+    // Do stuff with event.region.latitude, etc.
+  }
+
+  render() {
+    var region = {
+      latitude: 37.48,
+      longitude: -122.16,
+      latitudeDelta: 0.1,
+      longitudeDelta: 0.1,
+    };
+    return (
+      <MapView
+        region={region}
+        zoomEnabled={false}
+        onRegionChange={this.onRegionChange}
+      />
+    );
+  }  
+}
+
    
+

+  render: function() {
+    return (
+      <View style={this.props.style}>
+        <RCTDatePickerIOS
+          ref={DATEPICKER}
+          style={styles.rkDatePickerIOS}
+          ...
+        />
+      </View>
+    );
+  }
+});
+
+var styles = StyleSheet.create({
+  rkDatePickerIOS: {
+    height: RCTDatePickerIOSConsts.ComponentHeight,
+    width: RCTDatePickerIOSConsts.ComponentWidth,
+  },
+});
+
    
+
    The RCTDatePickerIOSConsts constants are exported from native by grabbing the actual frame of the native component like so:
    
+
    // RCTDatePickerManager.m
+
+- (NSDictionary *)constantsToExport
+{
+  UIDatePicker *dp = [[UIDatePicker alloc] init];
+  [dp layoutIfNeeded];
+
+  return @{
+    @"ComponentHeight": @(CGRectGetHeight(dp.frame)),
+    @"ComponentWidth": @(CGRectGetWidth(dp.frame)),
+    @"DatePickerModes": @{
+      @"time": @(UIDatePickerModeTime),
+      @"date": @(UIDatePickerModeDate),
+      @"datetime": @(UIDatePickerModeDateAndTime),
+    }
+  };
+}

    Native Modules
    Sometimes an app needs access to a platform API that React Native doesn't have a corresponding module for yet. Maybe you want to reuse some existing Java code without having to reimplement it in JavaScript, or write some high performance, multi-threaded code such as for image processing, a database, or any number of advanced extensions.
    
+
    We designed React Native such that it is possible for you to write real native code and have access to the full power of the platform. This is a more advanced feature and we don't expect it to be part of the usual development process, however it is essential that it exists. If React Native doesn't support a native feature that you need, you should be able to build it yourself.
    
+
    Native Module Setup
    
+
    Native modules are usually distributed as npm packages, apart from the typical javascript files and resources they will contain an Android library project. This project is, from NPM's perspective just like any other media asset, meaning there isn't anything special about it from this point of view. To get the basic scaffolding make sure to read Native Modules Setup guide first.
    
+
    Enable Gradle
    
+
    If you plan to make changes in Java code, we recommend enabling Gradle Daemon to speed up builds.
    
+
    The Toast Module
    
+
    This guide will use the Toast example. Let's say we would like to be able to create a toast message from JavaScript.
    
+
    We start by creating a native module. A native module is a Java class that usually extends the ReactContextBaseJavaModule class and implements the functionality required by the JavaScript. Our goal here is to be able to write ToastExample.show('Awesome', ToastExample.SHORT); from JavaScript to display a short toast on the screen.
    
+
    create a new Java Class named ToastModule.java inside android/app/src/main/java/com/your-app-name/ folder with the content below:
    
+
    // ToastModule.java
+
+package com.your-app-name;
+
+import android.widget.Toast;
+
+import com.facebook.react.bridge.NativeModule;
+import com.facebook.react.bridge.ReactApplicationContext;
+import com.facebook.react.bridge.ReactContext;
+import com.facebook.react.bridge.ReactContextBaseJavaModule;
+import com.facebook.react.bridge.ReactMethod;
+
+import java.util.Map;
+import java.util.HashMap;
+
+public class ToastModule extends ReactContextBaseJavaModule {
+
+  private static final String DURATION_SHORT_KEY = "SHORT";
+  private static final String DURATION_LONG_KEY = "LONG";
+
+  public ToastModule(ReactApplicationContext reactContext) {
+    super(reactContext);
+  }
+}
+
    
+
    ReactContextBaseJavaModule requires that a method called getName is implemented. The purpose of this method is to return the string name of the NativeModule which represents this class in JavaScript. So here we will call this ToastExample so that we can access it through React.NativeModules.ToastExample in JavaScript.
    
+
      @Override
+  public String getName() {
+    return "ToastExample";
+  }
+
    
+
    An optional method called getConstants returns the constant values exposed to JavaScript. Its implementation is not required but is very useful to key pre-defined values that need to be communicated from JavaScript to Java in sync.
    
+
      @Override
+  public Map<String, Object> getConstants() {
+    final Map<String, Object> constants = new HashMap<>();
+    constants.put(DURATION_SHORT_KEY, Toast.LENGTH_SHORT);
+    constants.put(DURATION_LONG_KEY, Toast.LENGTH_LONG);
+    return constants;
+  }
+
    
+
    To expose a method to JavaScript a Java method must be annotated using @ReactMethod. The return type of bridge methods is always void. React Native bridge is asynchronous, so the only way to pass a result to JavaScript is by using callbacks or emitting events (see below).
    
+
      @ReactMethod
+  public void show(String message, int duration) {
+    Toast.makeText(getReactApplicationContext(), message, duration).show();
+  }
+
    
+
    Argument Types
    
+
    The following argument types are supported for methods annotated with @ReactMethod and they directly map to their JavaScript equivalents
    
+
    Boolean -> Bool
+Integer -> Number
+Double -> Number
+Float -> Number
+String -> String
+Callback -> function
+ReadableMap -> Object
+ReadableArray -> Array
+
    
+
    Read more about ReadableMap and ReadableArray
    
+
    Register the Module
    
+
    The last step within Java is to register the Module; this happens in the createNativeModules of your apps package. If a module is not registered it will not be available from JavaScript.
    
+
    create a new Java Class named CustomToastPackage.java inside android/app/src/main/java/com/your-app-name/ folder with the content below:
    
+
    // CustomToastPackage.java
+
+package com.your-app-name;
+
+import com.facebook.react.ReactPackage;
+import com.facebook.react.bridge.NativeModule;
+import com.facebook.react.bridge.ReactApplicationContext;
+import com.facebook.react.uimanager.ViewManager;
+
+import java.util.ArrayList;
+import java.util.Collections;
+import java.util.List;
+
+public class CustomToastPackage implements ReactPackage {
+
+  @Override
+  public List<ViewManager> createViewManagers(ReactApplicationContext reactContext) {
+    return Collections.emptyList();
+  }
+
+  @Override
+  public List<NativeModule> createNativeModules(
+                              ReactApplicationContext reactContext) {
+    List<NativeModule> modules = new ArrayList<>();
+
+    modules.add(new ToastModule(reactContext));
+
+    return modules;
+  }
+
+}
+
    
+
    The package needs to be provided in the getPackages method of the MainApplication.java file. This file exists under the android folder in your react-native application directory. The path to this file is: android/app/src/main/java/com/your-app-name/MainApplication.java.
    
+
    // MainApplication.java
+
+...
+import com.your-app-name.CustomToastPackage; // <-- Add this line with your package name.
+...
+
+protected List<ReactPackage> getPackages() {
+    return Arrays.<ReactPackage>asList(
+            new MainReactPackage(),
+            new CustomToastPackage()); // <-- Add this line with your package name.
+}
+
    
+
    To make it simpler to access your new functionality from JavaScript, it is common to wrap the native module in a JavaScript module. This is not necessary but saves the consumers of your library the need to pull it off of NativeModules each time. This JavaScript file also becomes a good location for you to add any JavaScript side functionality.
    
+
    /**
+ * This exposes the native ToastExample module as a JS module. This has a
+ * function 'show' which takes the following parameters:
+ *
+ * 1. String message: A string with the text to toast
+ * 2. int duration: The duration of the toast. May be ToastExample.SHORT or
+ *    ToastExample.LONG
+ */
+import {NativeModules} from 'react-native';
+module.exports = NativeModules.ToastExample;
+
    
+
    Now, from your other JavaScript file you can call the method like this:
    
+
    import ToastExample from './ToastExample';
+
+ToastExample.show('Awesome', ToastExample.SHORT);
+
    
+
    Beyond Toasts
    
+
    Callbacks
    
+
    Native modules also support a special kind of argument - a callback. In most cases it is used to provide the function call result to JavaScript.
    
+
    import com.facebook.react.bridge.Callback;
+
+public class UIManagerModule extends ReactContextBaseJavaModule {
+
+...
+
+  @ReactMethod
+  public void measureLayout(
+      int tag,
+      int ancestorTag,
+      Callback errorCallback,
+      Callback successCallback) {
+    try {
+      measureLayout(tag, ancestorTag, mMeasureBuffer);
+      float relativeX = PixelUtil.toDIPFromPixel(mMeasureBuffer[0]);
+      float relativeY = PixelUtil.toDIPFromPixel(mMeasureBuffer[1]);
+      float width = PixelUtil.toDIPFromPixel(mMeasureBuffer[2]);
+      float height = PixelUtil.toDIPFromPixel(mMeasureBuffer[3]);
+      successCallback.invoke(relativeX, relativeY, width, height);
+    } catch (IllegalViewOperationException e) {
+      errorCallback.invoke(e.getMessage());
+    }
+  }
+
+...
+
    
+
    This method would be accessed in JavaScript using:
    
+
    UIManager.measureLayout(
+  100,
+  100,
+  (msg) => {
+    console.log(msg);
+  },
+  (x, y, width, height) => {
+    console.log(x + ':' + y + ':' + width + ':' + height);
+  },
+);
+
    
+
    A native module is supposed to invoke its callback only once. It can, however, store the callback and invoke it later.
    
+
    It is very important to highlight that the callback is not invoked immediately after the native function completes - remember that bridge communication is asynchronous, and this too is tied to the run loop.
    
+
    Promises
    
+
    Native modules can also fulfill a promise, which can simplify your code, especially when using ES2016's async/await syntax. When the last parameter of a bridged native method is a Promise, its corresponding JS method will return a JS Promise object.
    
+
    Refactoring the above code to use a promise instead of callbacks looks like this:
    
+
    import com.facebook.react.bridge.Promise;
+
+public class UIManagerModule extends ReactContextBaseJavaModule {
+
+...
+  private static final String E_LAYOUT_ERROR = "E_LAYOUT_ERROR";
+  @ReactMethod
+  public void measureLayout(
+      int tag,
+      int ancestorTag,
+      Promise promise) {
+    try {
+      measureLayout(tag, ancestorTag, mMeasureBuffer);
+
+      WritableMap map = Arguments.createMap();
+
+      map.putDouble("relativeX", PixelUtil.toDIPFromPixel(mMeasureBuffer[0]));
+      map.putDouble("relativeY", PixelUtil.toDIPFromPixel(mMeasureBuffer[1]));
+      map.putDouble("width", PixelUtil.toDIPFromPixel(mMeasureBuffer[2]));
+      map.putDouble("height", PixelUtil.toDIPFromPixel(mMeasureBuffer[3]));
+
+      promise.resolve(map);
+    } catch (IllegalViewOperationException e) {
+      promise.reject(E_LAYOUT_ERROR, e);
+    }
+  }
+
+...
+
    
+
    The JavaScript counterpart of this method returns a Promise. This means you can use the await keyword within an async function to call it and wait for its result:
    
+
    async function measureLayout() {
+  try {
+    var {relativeX, relativeY, width, height} = await UIManager.measureLayout(
+      100,
+      100,
+    );
+
+    console.log(relativeX + ':' + relativeY + ':' + width + ':' + height);
+  } catch (e) {
+    console.error(e);
+  }
+}
+
+measureLayout();
+
    
+
    Threading
    
+
    Native modules should not have any assumptions about what thread they are being called on, as the current assignment is subject to change in the future. If a blocking call is required, the heavy work should be dispatched to an internally managed worker thread, and any callbacks distributed from there.
    
+
    Sending Events to JavaScript
    
+
    Native modules can signal events to JavaScript without being invoked directly. The easiest way to do this is to use the RCTDeviceEventEmitter which can be obtained from the ReactContext as in the code snippet below.
    
+
    ...
+private void sendEvent(ReactContext reactContext,
+                       String eventName,
+                       @Nullable WritableMap params) {
+  reactContext
+      .getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
+      .emit(eventName, params);
+}
+...
+WritableMap params = Arguments.createMap();
+...
+sendEvent(reactContext, "keyboardWillShow", params);
+
    
+
    JavaScript modules can then register to receive events by addListenerOn using the Subscribable mixin.
    
+
    import { DeviceEventEmitter } from 'react-native';
+...
+
+var ScrollResponderMixin = {
+  mixins: [Subscribable.Mixin],
+
+
+  componentWillMount: function() {
+    ...
+    this.addListenerOn(DeviceEventEmitter,
+                       'keyboardWillShow',
+                       this.scrollResponderKeyboardWillShow);
+    ...
+  },
+  scrollResponderKeyboardWillShow:function(e: Event) {
+    this.keyboardWillOpenTo = e;
+    this.props.onKeyboardWillShow && this.props.onKeyboardWillShow(e);
+  },
+
    
+
    You can also directly use the DeviceEventEmitter module to listen for events.
    
+
    ...
+componentWillMount: function() {
+  DeviceEventEmitter.addListener('keyboardWillShow', function(e: Event) {
+    // handle event.
+  });
+}
+...
+
    
+
    Getting activity result from startActivityForResult
    
+
    You'll need to listen to onActivityResult if you want to get results from an activity you started with startActivityForResult. To do this, you must extend BaseActivityEventListener or implement ActivityEventListener. The former is preferred as it is more resilient to API changes. Then, you need to register the listener in the module's constructor,
    
+
    reactContext.addActivityEventListener(mActivityResultListener);
+
    
+
    Now you can listen to onActivityResult by implementing the following method:
    
+
    @Override
+public void onActivityResult(
+  final Activity activity,
+  final int requestCode,
+  final int resultCode,
+  final Intent intent) {
+  // Your logic here
+}
+
    
+
    We will implement a simple image picker to demonstrate this. The image picker will expose the method pickImage to JavaScript, which will return the path of the image when called.
    
+
    public class ImagePickerModule extends ReactContextBaseJavaModule {
+
+  private static final int IMAGE_PICKER_REQUEST = 467081;
+  private static final String E_ACTIVITY_DOES_NOT_EXIST = "E_ACTIVITY_DOES_NOT_EXIST";
+  private static final String E_PICKER_CANCELLED = "E_PICKER_CANCELLED";
+  private static final String E_FAILED_TO_SHOW_PICKER = "E_FAILED_TO_SHOW_PICKER";
+  private static final String E_NO_IMAGE_DATA_FOUND = "E_NO_IMAGE_DATA_FOUND";
+
+  private Promise mPickerPromise;
+
+  private final ActivityEventListener mActivityEventListener = new BaseActivityEventListener() {
+
+    @Override
+    public void onActivityResult(Activity activity, int requestCode, int resultCode, Intent intent) {
+      if (requestCode == IMAGE_PICKER_REQUEST) {
+        if (mPickerPromise != null) {
+          if (resultCode == Activity.RESULT_CANCELED) {
+            mPickerPromise.reject(E_PICKER_CANCELLED, "Image picker was cancelled");
+          } else if (resultCode == Activity.RESULT_OK) {
+            Uri uri = intent.getData();
+
+            if (uri == null) {
+              mPickerPromise.reject(E_NO_IMAGE_DATA_FOUND, "No image data found");
+            } else {
+              mPickerPromise.resolve(uri.toString());
+            }
+          }
+
+          mPickerPromise = null;
+        }
+      }
+    }
+  };
+
+  public ImagePickerModule(ReactApplicationContext reactContext) {
+    super(reactContext);
+
+    // Add the listener for `onActivityResult`
+    reactContext.addActivityEventListener(mActivityEventListener);
+  }
+
+  @Override
+  public String getName() {
+    return "ImagePickerModule";
+  }
+
+  @ReactMethod
+  public void pickImage(final Promise promise) {
+    Activity currentActivity = getCurrentActivity();
+
+    if (currentActivity == null) {
+      promise.reject(E_ACTIVITY_DOES_NOT_EXIST, "Activity doesn't exist");
+      return;
+    }
+
+    // Store the promise to resolve/reject when picker returns data
+    mPickerPromise = promise;
+
+    try {
+      final Intent galleryIntent = new Intent(Intent.ACTION_PICK);
+
+      galleryIntent.setType("image/*");
+
+      final Intent chooserIntent = Intent.createChooser(galleryIntent, "Pick an image");
+
+      currentActivity.startActivityForResult(chooserIntent, IMAGE_PICKER_REQUEST);
+    } catch (Exception e) {
+      mPickerPromise.reject(E_FAILED_TO_SHOW_PICKER, e);
+      mPickerPromise = null;
+    }
+  }
+}
+
    
+
    Listening to LifeCycle events
    
+
    Listening to the activity's LifeCycle events such as onResume, onPause etc. is very similar to how we implemented ActivityEventListener. The module must implement LifecycleEventListener. Then, you need to register a listener in the module's constructor,
    
+
    reactContext.addLifecycleEventListener(this);
+
    
+
    Now you can listen to the activity's LifeCycle events by implementing the following methods:
    
+
    @Override
+public void onHostResume() {
+    // Activity `onResume`
+}
+
+@Override
+public void onHostPause() {
+    // Activity `onPause`
+}
+
+@Override
+public void onHostDestroy() {
+    // Activity `onDestroy`
+}
+

    // CustomToastPackage.java

+package com.your-app-name;

    Beyond Toasts
    
+
    Callbacks
    
+
    Native modules also support a special kind of argument - a callback. In most cases it is used to provide the function call result to JavaScript.
    
+
    import com.facebook.react.bridge.Callback;
+
+public class UIManagerModule extends ReactContextBaseJavaModule {
+
+...
+
+  @ReactMethod
+  public void measureLayout(
+      int tag,
+      int ancestorTag,
+      Callback errorCallback,
+      Callback successCallback) {
+    try {
+      measureLayout(tag, ancestorTag, mMeasureBuffer);
+      float relativeX = PixelUtil.toDIPFromPixel(mMeasureBuffer[0]);
+      float relativeY = PixelUtil.toDIPFromPixel(mMeasureBuffer[1]);
+      float width = PixelUtil.toDIPFromPixel(mMeasureBuffer[2]);
+      float height = PixelUtil.toDIPFromPixel(mMeasureBuffer[3]);
+      successCallback.invoke(relativeX, relativeY, width, height);
+    } catch (IllegalViewOperationException e) {
+      errorCallback.invoke(e.getMessage());
+    }
+  }
+
+...
+
    
+
    This method would be accessed in JavaScript using:
    
+
    UIManager.measureLayout(
+  100,
+  100,
+  (msg) => {
+    console.log(msg);
+  },
+  (x, y, width, height) => {
+    console.log(x + ':' + y + ':' + width + ':' + height);
+  },
+);
+
    
+
    A native module is supposed to invoke its callback only once. It can, however, store the callback and invoke it later.
    
+
    It is very important to highlight that the callback is not invoked immediately after the native function completes - remember that bridge communication is asynchronous, and this too is tied to the run loop.
    
+
    Promises
    
+
    Native modules can also fulfill a promise, which can simplify your code, especially when using ES2016's async/await syntax. When the last parameter of a bridged native method is a Promise, its corresponding JS method will return a JS Promise object.
    
+
    Refactoring the above code to use a promise instead of callbacks looks like this:
    
+
    import com.facebook.react.bridge.Promise;
+
+public class UIManagerModule extends ReactContextBaseJavaModule {
+
+...
+  private static final String E_LAYOUT_ERROR = "E_LAYOUT_ERROR";
+  @ReactMethod
+  public void measureLayout(
+      int tag,
+      int ancestorTag,
+      Promise promise) {
+    try {
+      measureLayout(tag, ancestorTag, mMeasureBuffer);
+
+      WritableMap map = Arguments.createMap();
+
+      map.putDouble("relativeX", PixelUtil.toDIPFromPixel(mMeasureBuffer[0]));
+      map.putDouble("relativeY", PixelUtil.toDIPFromPixel(mMeasureBuffer[1]));
+      map.putDouble("width", PixelUtil.toDIPFromPixel(mMeasureBuffer[2]));
+      map.putDouble("height", PixelUtil.toDIPFromPixel(mMeasureBuffer[3]));
+
+      promise.resolve(map);
+    } catch (IllegalViewOperationException e) {
+      promise.reject(E_LAYOUT_ERROR, e);
+    }
+  }
+
+...
+
    
+
    The JavaScript counterpart of this method returns a Promise. This means you can use the await keyword within an async function to call it and wait for its result:
    
+
    async function measureLayout() {
+  try {
+    var {relativeX, relativeY, width, height} = await UIManager.measureLayout(
+      100,
+      100,
+    );
+
+    console.log(relativeX + ':' + relativeY + ':' + width + ':' + height);
+  } catch (e) {
+    console.error(e);
+  }
+}
+
+measureLayout();
+
    
+
    Threading
    
+
    Native modules should not have any assumptions about what thread they are being called on, as the current assignment is subject to change in the future. If a blocking call is required, the heavy work should be dispatched to an internally managed worker thread, and any callbacks distributed from there.
    
+
    Sending Events to JavaScript
    
+
    Native modules can signal events to JavaScript without being invoked directly. The easiest way to do this is to use the RCTDeviceEventEmitter which can be obtained from the ReactContext as in the code snippet below.
    
+
    ...
+private void sendEvent(ReactContext reactContext,
+                       String eventName,
+                       @Nullable WritableMap params) {
+  reactContext
+      .getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
+      .emit(eventName, params);
+}
+...
+WritableMap params = Arguments.createMap();
+...
+sendEvent(reactContext, "keyboardWillShow", params);
+
    
+
    JavaScript modules can then register to receive events by addListenerOn using the Subscribable mixin.
    
+
    import { DeviceEventEmitter } from 'react-native';
+...
+
+var ScrollResponderMixin = {
+  mixins: [Subscribable.Mixin],
+
+
+  componentWillMount: function() {
+    ...
+    this.addListenerOn(DeviceEventEmitter,
+                       'keyboardWillShow',
+                       this.scrollResponderKeyboardWillShow);
+    ...
+  },
+  scrollResponderKeyboardWillShow:function(e: Event) {
+    this.keyboardWillOpenTo = e;
+    this.props.onKeyboardWillShow && this.props.onKeyboardWillShow(e);
+  },
+
    
+
    You can also directly use the DeviceEventEmitter module to listen for events.
    
+
    ...
+componentWillMount: function() {
+  DeviceEventEmitter.addListener('keyboardWillShow', function(e: Event) {
+    // handle event.
+  });
+}
+...
+
    
+
    Getting activity result from startActivityForResult
    
+
    You'll need to listen to onActivityResult if you want to get results from an activity you started with startActivityForResult. To do this, you must extend BaseActivityEventListener or implement ActivityEventListener. The former is preferred as it is more resilient to API changes. Then, you need to register the listener in the module's constructor,
    
+
    reactContext.addActivityEventListener(mActivityResultListener);
+
    
+
    Now you can listen to onActivityResult by implementing the following method:
    
+
    @Override
+public void onActivityResult(
+  final Activity activity,
+  final int requestCode,
+  final int resultCode,
+  final Intent intent) {
+  // Your logic here
+}
+
    
+
    We will implement a simple image picker to demonstrate this. The image picker will expose the method pickImage to JavaScript, which will return the path of the image when called.
    
+
    public class ImagePickerModule extends ReactContextBaseJavaModule {
+
+  private static final int IMAGE_PICKER_REQUEST = 467081;
+  private static final String E_ACTIVITY_DOES_NOT_EXIST = "E_ACTIVITY_DOES_NOT_EXIST";
+  private static final String E_PICKER_CANCELLED = "E_PICKER_CANCELLED";
+  private static final String E_FAILED_TO_SHOW_PICKER = "E_FAILED_TO_SHOW_PICKER";
+  private static final String E_NO_IMAGE_DATA_FOUND = "E_NO_IMAGE_DATA_FOUND";
+
+  private Promise mPickerPromise;
+
+  private final ActivityEventListener mActivityEventListener = new BaseActivityEventListener() {
+
+    @Override
+    public void onActivityResult(Activity activity, int requestCode, int resultCode, Intent intent) {
+      if (requestCode == IMAGE_PICKER_REQUEST) {
+        if (mPickerPromise != null) {
+          if (resultCode == Activity.RESULT_CANCELED) {
+            mPickerPromise.reject(E_PICKER_CANCELLED, "Image picker was cancelled");
+          } else if (resultCode == Activity.RESULT_OK) {
+            Uri uri = intent.getData();
+
+            if (uri == null) {
+              mPickerPromise.reject(E_NO_IMAGE_DATA_FOUND, "No image data found");
+            } else {
+              mPickerPromise.resolve(uri.toString());
+            }
+          }
+
+          mPickerPromise = null;
+        }
+      }
+    }
+  };
+
+  public ImagePickerModule(ReactApplicationContext reactContext) {
+    super(reactContext);
+
+    // Add the listener for `onActivityResult`
+    reactContext.addActivityEventListener(mActivityEventListener);
+  }
+
+  @Override
+  public String getName() {
+    return "ImagePickerModule";
+  }
+
+  @ReactMethod
+  public void pickImage(final Promise promise) {
+    Activity currentActivity = getCurrentActivity();
+
+    if (currentActivity == null) {
+      promise.reject(E_ACTIVITY_DOES_NOT_EXIST, "Activity doesn't exist");
+      return;
+    }
+
+    // Store the promise to resolve/reject when picker returns data
+    mPickerPromise = promise;
+
+    try {
+      final Intent galleryIntent = new Intent(Intent.ACTION_PICK);
+
+      galleryIntent.setType("image/*");
+
+      final Intent chooserIntent = Intent.createChooser(galleryIntent, "Pick an image");
+
+      currentActivity.startActivityForResult(chooserIntent, IMAGE_PICKER_REQUEST);
+    } catch (Exception e) {
+      mPickerPromise.reject(E_FAILED_TO_SHOW_PICKER, e);
+      mPickerPromise = null;
+    }
+  }
+}
+
    
+
    Listening to LifeCycle events
    
+
    Listening to the activity's LifeCycle events such as onResume, onPause etc. is very similar to how we implemented ActivityEventListener. The module must implement LifecycleEventListener. Then, you need to register a listener in the module's constructor,
    
+
    reactContext.addLifecycleEventListener(this);
+
    
+
    Now you can listen to the activity's LifeCycle events by implementing the following methods:
    
+
    @Override
+public void onHostResume() {
+    // Activity `onResume`
+}
+
+@Override
+public void onHostPause() {
+    // Activity `onPause`
+}
+
+@Override
+public void onHostDestroy() {
+    // Activity `onDestroy`
+}
+

    Native Modules
    Sometimes an app needs to access a platform API and React Native doesn't have a corresponding module yet. Maybe you want to reuse some existing Objective-C, Swift or C++ code without having to reimplement it in JavaScript, or write some high performance, multi-threaded code such as for image processing, a database, or any number of advanced extensions.
    
+
    We designed React Native such that it is possible for you to write real native code and have access to the full power of the platform. This is a more advanced feature and we don't expect it to be part of the usual development process, however it is essential that it exists. If React Native doesn't support a native feature that you need, you should be able to build it yourself.
    
+
    This is a more advanced guide that shows how to build a native module. It assumes the reader knows Objective-C or Swift and core libraries (Foundation, UIKit).
    
+
    Native Module Setup
    
+
    Native modules are usually distributed as npm packages, except that for them to be native modules they will contain an Xcode library project. To get the basic scaffolding make sure to read Native Modules Setup guide first.
    
+
    iOS Calendar Module Example
    
+
    This guide will use the iOS Calendar API example. Let's say we would like to be able to access the iOS calendar from JavaScript.
    
+
    A native module is just an Objective-C class that implements the RCTBridgeModule protocol. If you are wondering, RCT is an abbreviation of ReaCT.
    
+
    // CalendarManager.h
+#import <React/RCTBridgeModule.h>
+
+@interface CalendarManager : NSObject <RCTBridgeModule>
+@end
+
    
+
    In addition to implementing the RCTBridgeModule protocol, your class must also include the RCT_EXPORT_MODULE() macro. This takes an optional argument that specifies the name that the module will be accessible as in your JavaScript code (more on this later). If you do not specify a name, the JavaScript module name will match the Objective-C class name. If the Objective-C class name begins with RCT, the JavaScript module name will exclude the RCT prefix.
    
+
    // CalendarManager.m
+#import "CalendarManager.h"
+
+@implementation CalendarManager
+
+// To export a module named CalendarManager
+RCT_EXPORT_MODULE();
+
+// This would name the module AwesomeCalendarManager instead
+// RCT_EXPORT_MODULE(AwesomeCalendarManager);
+
+@end
+
    
+
    React Native will not expose any methods of CalendarManager to JavaScript unless explicitly told to. This is done using the RCT_EXPORT_METHOD() macro:
    
+
    #import "CalendarManager.h"
+#import <React/RCTLog.h>
+
+@implementation CalendarManager
+
+RCT_EXPORT_MODULE();
+
+RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location)
+{
+  RCTLogInfo(@"Pretending to create an event %@ at %@", name, location);
+}
+
+@end
+
    
+
    Now, from your JavaScript file you can call the method like this:
    
+
    import {NativeModules} from 'react-native';
+var CalendarManager = NativeModules.CalendarManager;
+CalendarManager.addEvent('Birthday Party', '4 Privet Drive, Surrey');
+
    
+
    
+
    NOTE: JavaScript method names
    
+
    The name of the method exported to JavaScript is the native method's name up to the first colon. React Native also defines a macro called RCT_REMAP_METHOD() to specify the JavaScript method's name. This is useful when multiple native methods are the same up to the first colon and would have conflicting JavaScript names.
    
+
    
+
    The CalendarManager module is instantiated on the Objective-C side using a [CalendarManager new] call. The return type of bridge methods is always void. React Native bridge is asynchronous, so the only way to pass a result to JavaScript is by using callbacks or emitting events (see below).
    
+
    Argument Types
    
+
    RCT_EXPORT_METHOD supports all standard JSON object types, such as:
    
+
      
+
    • string (NSString)
      • 
+
    • number (NSInteger, float, double, CGFloat, NSNumber)
      • 
+
    • boolean (BOOL, NSNumber)
      • 
+
    • array (NSArray) of any types from this list
      • 
+
    • object (NSDictionary) with string keys and values of any type from this list
      • 
+
    • function (RCTResponseSenderBlock)
      • 
+
    
+
    But it also works with any type that is supported by the RCTConvert class (see RCTConvert for details). The RCTConvert helper functions all accept a JSON value as input and map it to a native Objective-C type or class.
    
+
    In our CalendarManager example, we need to pass the event date to the native method. We can't send JavaScript Date objects over the bridge, so we need to convert the date to a string or number. We could write our native function like this:
    
+
    RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location date:(nonnull NSNumber *)secondsSinceUnixEpoch)
+{
+  NSDate *date = [RCTConvert NSDate:secondsSinceUnixEpoch];
+}
+
    
+
    or like this:
    
+
    RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location date:(NSString *)ISO8601DateString)
+{
+  NSDate *date = [RCTConvert NSDate:ISO8601DateString];
+}
+
    
+
    But by using the automatic type conversion feature, we can skip the manual conversion step completely, and just write:
    
+
    RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location date:(NSDate *)date)
+{
+  // Date is ready to use!
+}
+
    
+
    You would then call this from JavaScript by using either:
    
+
    CalendarManager.addEvent(
+  'Birthday Party',
+  '4 Privet Drive, Surrey',
+  date.getTime(),
+); // passing date as number of milliseconds since Unix epoch
+
    
+
    or
    
+
    CalendarManager.addEvent(
+  'Birthday Party',
+  '4 Privet Drive, Surrey',
+  date.toISOString(),
+); // passing date as ISO-8601 string
+
    
+
    And both values would get converted correctly to the native NSDate. A bad value, like an Array, would generate a helpful "RedBox" error message.
    
+
    As CalendarManager.addEvent method gets more and more complex, the number of arguments will grow. Some of them might be optional. In this case it's worth considering changing the API a little bit to accept a dictionary of event attributes, like this:
    
+
    #import <React/RCTConvert.h>
+
+RCT_EXPORT_METHOD(addEvent:(NSString *)name details:(NSDictionary *)details)
+{
+  NSString *location = [RCTConvert NSString:details[@"location"]];
+  NSDate *time = [RCTConvert NSDate:details[@"time"]];
+  ...
+}
+
    
+
    and call it from JavaScript:
    
+
    CalendarManager.addEvent('Birthday Party', {
+  location: '4 Privet Drive, Surrey',
+  time: date.getTime(),
+  description: '...',
+});
+
    
+
    
+
    NOTE: About array and map
    
+
    Objective-C doesn't provide any guarantees about the types of values in these structures. Your native module might expect an array of strings, but if JavaScript calls your method with an array containing numbers and strings, you'll get an NSArray containing a mix of NSNumber and NSString. For arrays, RCTConvert provides some typed collections you can use in your method declaration, such as NSStringArray, or UIColorArray. For maps, it is the developer's responsibility to check the value types individually by manually calling RCTConvert helper methods.
    
+
    
+
    Callbacks
    
+
    
+
    WARNING
    
+
    This section is more experimental than others because we don't have a solid set of best practices around callbacks yet.
    
+
    
+
    Native modules also supports a special kind of argument- a callback. In most cases it is used to provide the function call result to JavaScript.
    
+
    RCT_EXPORT_METHOD(findEvents:(RCTResponseSenderBlock)callback)
+{
+  NSArray *events = ...
+  callback(@[[NSNull null], events]);
+}
+
    
+
    RCTResponseSenderBlock accepts only one argument - an array of parameters to pass to the JavaScript callback. In this case we use Node's convention to make the first parameter an error object (usually null when there is no error) and the rest are the results of the function.
    
+
    CalendarManager.findEvents((error, events) => {
+  if (error) {
+    console.error(error);
+  } else {
+    this.setState({events: events});
+  }
+});
+
    
+
    A native module should invoke its callback exactly once. It's okay to store the callback and invoke it later. This pattern is often used to wrap iOS APIs that require delegates - see RCTAlertManager for an example. If the callback is never invoked, some memory is leaked. If both onSuccess and onFail callbacks are passed, you should only invoke one of them.
    
+
    If you want to pass error-like objects to JavaScript, use RCTMakeError from RCTUtils.h. Right now this just passes an Error-shaped dictionary to JavaScript, but we would like to automatically generate real JavaScript Error objects in the future.
    
+
    Promises
    
+
    Native modules can also fulfill a promise, which can simplify your code, especially when using ES2016's async/await syntax. When the last parameters of a bridged native method are an RCTPromiseResolveBlock and RCTPromiseRejectBlock, its corresponding JS method will return a JS Promise object.
    
+
    Refactoring the above code to use a promise instead of callbacks looks like this:
    
+
    RCT_REMAP_METHOD(findEvents,
+                 findEventsWithResolver:(RCTPromiseResolveBlock)resolve
+                 rejecter:(RCTPromiseRejectBlock)reject)
+{
+  NSArray *events = ...
+  if (events) {
+    resolve(events);
+  } else {
+    NSError *error = ...
+    reject(@"no_events", @"There were no events", error);
+  }
+}
+
    
+
    The JavaScript counterpart of this method returns a Promise. This means you can use the await keyword within an async function to call it and wait for its result:
    
+
    async function updateEvents() {
+  try {
+    var events = await CalendarManager.findEvents();
+
+    this.setState({events});
+  } catch (e) {
+    console.error(e);
+  }
+}
+
+updateEvents();
+
    
+
    Threading
    
+
    The native module should not have any assumptions about what thread it is being called on. React Native invokes native modules methods on a separate serial GCD queue, but this is an implementation detail and might change. The - (dispatch_queue_t)methodQueue method allows the native module to specify which queue its methods should be run on. For example, if it needs to use a main-thread-only iOS API, it should specify this via:
    
+
    - (dispatch_queue_t)methodQueue
+{
+  return dispatch_get_main_queue();
+}
+
    
+
    Similarly, if an operation may take a long time to complete, the native module should not block and can specify it's own queue to run operations on. For example, the RCTAsyncLocalStorage module creates its own queue so the React queue isn't blocked waiting on potentially slow disk access:
    
+
    - (dispatch_queue_t)methodQueue
+{
+  return dispatch_queue_create("com.facebook.React.AsyncLocalStorageQueue", DISPATCH_QUEUE_SERIAL);
+}
+
    
+
    The specified methodQueue will be shared by all of the methods in your module. If just one of your methods is long-running (or needs to be run on a different queue than the others for some reason), you can use dispatch_async inside the method to perform that particular method's code on another queue, without affecting the others:
    
+
    RCT_EXPORT_METHOD(doSomethingExpensive:(NSString *)param callback:(RCTResponseSenderBlock)callback)
+{
+  dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
+    // Call long-running code on background thread
+    ...
+    // You can invoke callback from any thread/queue
+    callback(@[...]);
+  });
+}
+
    
+
    
+
    NOTE: Sharing dispatch queues between modules
    
+
    The methodQueue method will be called once when the module is initialized, and then retained by the bridge, so there is no need to retain the queue yourself, unless you wish to make use of it within your module. However, if you wish to share the same queue between multiple modules then you will need to ensure that you retain and return the same queue instance for each of them; merely returning a queue of the same name for each won't work.
    
+
    
+
    Dependency Injection
    
+
    The bridge initializes any registered RCTBridgeModules automatically, however you may wish to instantiate your own module instances (so you may inject dependencies, for example).
    
+
    You can do this by creating a class that implements the RCTBridgeDelegate Protocol, initializing an RCTBridge with the delegate as an argument and initialising a RCTRootView with the initialized bridge.
    
+
    id<RCTBridgeDelegate> moduleInitialiser = [[classThatImplementsRCTBridgeDelegate alloc] init];
+
+RCTBridge *bridge = [[RCTBridge alloc] initWithDelegate:moduleInitialiser launchOptions:nil];
+
+RCTRootView *rootView = [[RCTRootView alloc]
+                        initWithBridge:bridge
+                            moduleName:kModuleName
+                     initialProperties:nil];
+
    
+
    Exporting Constants
    
+
    A native module can export constants that are immediately available to JavaScript at runtime. This is useful for communicating static data that would otherwise require a round-trip through the bridge.
    
+
    - (NSDictionary *)constantsToExport
+{
+  return @{ @"firstDayOfTheWeek": @"Monday" };
+}
+
    
+
    JavaScript can use this value right away, synchronously:
    
+
    console.log(CalendarManager.firstDayOfTheWeek);
+
    
+
    Note that the constants are exported only at initialization time, so if you change constantsToExport values at runtime it won't affect the JavaScript environment.
    
+
    Enum Constants
    
+
    Enums that are defined via NS_ENUM cannot be used as method arguments without first extending RCTConvert.
    
+
    In order to export the following NS_ENUM definition:
    
+
    typedef NS_ENUM(NSInteger, UIStatusBarAnimation) {
+    UIStatusBarAnimationNone,
+    UIStatusBarAnimationFade,
+    UIStatusBarAnimationSlide,
+};
+
    
+
    You must create a class extension of RCTConvert like so:
    
+
    @implementation RCTConvert (StatusBarAnimation)
+  RCT_ENUM_CONVERTER(UIStatusBarAnimation, (@{ @"statusBarAnimationNone" : @(UIStatusBarAnimationNone),
+                                               @"statusBarAnimationFade" : @(UIStatusBarAnimationFade),
+                                               @"statusBarAnimationSlide" : @(UIStatusBarAnimationSlide)}),
+                      UIStatusBarAnimationNone, integerValue)
+@end
+
    
+
    You can then define methods and export your enum constants like this:
    
+
    - (NSDictionary *)constantsToExport
+{
+  return @{ @"statusBarAnimationNone" : @(UIStatusBarAnimationNone),
+            @"statusBarAnimationFade" : @(UIStatusBarAnimationFade),
+            @"statusBarAnimationSlide" : @(UIStatusBarAnimationSlide) };
+};
+
+RCT_EXPORT_METHOD(updateStatusBarAnimation:(UIStatusBarAnimation)animation
+                                completion:(RCTResponseSenderBlock)callback)
+
    
+
    Your enum will then be automatically unwrapped using the selector provided (integerValue in the above example) before being passed to your exported method.
    
+
    Sending Events to JavaScript
    
+
    The native module can signal events to JavaScript without being invoked directly. The preferred way to do this is to subclass RCTEventEmitter, implement supportedEvents and call self sendEventWithName:
    
+
    // CalendarManager.h
+#import <React/RCTBridgeModule.h>
+#import <React/RCTEventEmitter.h>
+
+@interface CalendarManager : RCTEventEmitter <RCTBridgeModule>
+
+@end
+
    
+
    // CalendarManager.m
+#import "CalendarManager.h"
+
+@implementation CalendarManager
+
+RCT_EXPORT_MODULE();
+
+- (NSArray<NSString *> *)supportedEvents
+{
+  return @[@"EventReminder"];
+}
+
+- (void)calendarEventReminderReceived:(NSNotification *)notification
+{
+  NSString *eventName = notification.userInfo[@"name"];
+  [self sendEventWithName:@"EventReminder" body:@{@"name": eventName}];
+}
+
+@end
+
    
+
    JavaScript code can subscribe to these events by creating a new NativeEventEmitter instance around your module.
    
+
    import { NativeEventEmitter, NativeModules } from 'react-native';
+const { CalendarManager } = NativeModules;
+
+const calendarManagerEmitter = new NativeEventEmitter(CalendarManager);
+
+const subscription = calendarManagerEmitter.addListener(
+  'EventReminder',
+  (reminder) => console.log(reminder.name)
+);
+...
+// Don't forget to unsubscribe, typically in componentWillUnmount
+subscription.remove();
+
    
+
    For more examples of sending events to JavaScript, see RCTLocationObserver.
    
+
    Optimizing for zero listeners
    
+
    You will receive a warning if you expend resources unnecessarily by emitting an event while there are no listeners. To avoid this, and to optimize your module's workload (e.g. by unsubscribing from upstream notifications or pausing background tasks), you can override startObserving and stopObserving in your RCTEventEmitter subclass.
    
+
    @implementation CalendarManager
+{
+  bool hasListeners;
+}
+
+// Will be called when this module's first listener is added.
+-(void)startObserving {
+    hasListeners = YES;
+    // Set up any upstream listeners or background tasks as necessary
+}
+
+// Will be called when this module's last listener is removed, or on dealloc.
+-(void)stopObserving {
+    hasListeners = NO;
+    // Remove upstream listeners, stop unnecessary background tasks
+}
+
+- (void)calendarEventReminderReceived:(NSNotification *)notification
+{
+  NSString *eventName = notification.userInfo[@"name"];
+  if (hasListeners) { // Only send events if anyone is listening
+    [self sendEventWithName:@"EventReminder" body:@{@"name": eventName}];
+  }
+}
+
    
+
    Exporting Swift
    
+
    Swift doesn't have support for macros so exposing it to React Native requires a bit more setup but works relatively the same.
    
+
    Let's say we have the same CalendarManager but as a Swift class:
    
+
    // CalendarManager.swift
+
+@objc(CalendarManager)
+class CalendarManager: NSObject {
+
+  @objc(addEvent:location:date:)
+  func addEvent(name: String, location: String, date: NSNumber) -> Void {
+    // Date is ready to use!
+  }
+
+  @objc
+  func constantsToExport() -> [String: Any]! {
+    return ["someKey": "someValue"]
+  }
+
+}
+
    
+
    
+
    NOTE: It is important to use the @objc modifiers to ensure the class and functions are exported properly to the Objective-C runtime.
    
+
    
+
    Then create a private implementation file that will register the required information with the React Native bridge:
    
+
    // CalendarManagerBridge.m
+#import <React/RCTBridgeModule.h>
+
+@interface RCT_EXTERN_MODULE(CalendarManager, NSObject)
+
+RCT_EXTERN_METHOD(addEvent:(NSString *)name location:(NSString *)location date:(nonnull NSNumber *)date)
+
+@end
+
    
+
    For those of you new to Swift and Objective-C, whenever you mix the two languages in an iOS project, you will also need an additional bridging file, known as a bridging header, to expose the Objective-C files to Swift. Xcode will offer to create this header file for you if you add your Swift file to your app through the Xcode File>New File menu option. You will need to import RCTBridgeModule.h in this header file.
    
+
    // CalendarManager-Bridging-Header.h
+#import <React/RCTBridgeModule.h>
+
    
+
    You can also use RCT_EXTERN_REMAP_MODULE and _RCT_EXTERN_REMAP_METHOD to alter the JavaScript name of the module or methods you are exporting. For more information see RCTBridgeModule.
    
+
    
+
    Important when making third party modules: Static libraries with Swift are only supported in Xcode 9 and later. In order for the Xcode project to build when you use Swift in the iOS static library you include in the module, your main app project must contain Swift code and a bridging header itself. If your app project does not contain any Swift code, a workaround can be a single empty .swift file and an empty bridging header.

    Native Modules
    Sometimes an app needs to access a platform API and React Native doesn't have a corresponding module yet. Maybe you want to reuse some existing Objective-C, Swift or C++ code without having to reimplement it in JavaScript, or write some high performance, multi-threaded code such as for image processing, a database, or any number of advanced extensions.
    
+
    We designed React Native such that it is possible for you to write real native code and have access to the full power of the platform. This is a more advanced feature and we don't expect it to be part of the usual development process, however it is essential that it exists. If React Native doesn't support a native feature that you need, you should be able to build it yourself.
    
+
    This is a more advanced guide that shows how to build a native module. It assumes the reader knows Objective-C or Swift and core libraries (Foundation, UIKit).
    
+
    Native Module Setup
    
+
    Native modules are usually distributed as npm packages, except that for them to be native modules they will contain an Xcode library project. To get the basic scaffolding make sure to read Native Modules Setup guide first.
    
+
    iOS Calendar Module Example
    
+
    This guide will use the iOS Calendar API example. Let's say we would like to be able to access the iOS calendar from JavaScript.
    
+
    A native module is just an Objective-C class that implements the RCTBridgeModule protocol. If you are wondering, RCT is an abbreviation of ReaCT.
    
+
    // CalendarManager.h
+#import <React/RCTBridgeModule.h>
+
+@interface CalendarManager : NSObject <RCTBridgeModule>
+@end
+
    
+
    In addition to implementing the RCTBridgeModule protocol, your class must also include the RCT_EXPORT_MODULE() macro. This takes an optional argument that specifies the name that the module will be accessible as in your JavaScript code (more on this later). If you do not specify a name, the JavaScript module name will match the Objective-C class name. If the Objective-C class name begins with RCT, the JavaScript module name will exclude the RCT prefix.
    
+
    // CalendarManager.m
+#import "CalendarManager.h"
+
+@implementation CalendarManager
+
+// To export a module named CalendarManager
+RCT_EXPORT_MODULE();
+
+// This would name the module AwesomeCalendarManager instead
+// RCT_EXPORT_MODULE(AwesomeCalendarManager);
+
+@end
+
    
+
    React Native will not expose any methods of CalendarManager to JavaScript unless explicitly told to. This is done using the RCT_EXPORT_METHOD() macro:
    
+
    #import "CalendarManager.h"
+#import <React/RCTLog.h>
+
+@implementation CalendarManager
+
+RCT_EXPORT_MODULE();
+
+RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location)
+{
+  RCTLogInfo(@"Pretending to create an event %@ at %@", name, location);
+}
+
+@end
+
    
+
    Now, from your JavaScript file you can call the method like this:
    
+
    import {NativeModules} from 'react-native';
+var CalendarManager = NativeModules.CalendarManager;
+CalendarManager.addEvent('Birthday Party', '4 Privet Drive, Surrey');
+
    
+
    
+
    NOTE: JavaScript method names
    
+
    The name of the method exported to JavaScript is the native method's name up to the first colon. React Native also defines a macro called RCT_REMAP_METHOD() to specify the JavaScript method's name. This is useful when multiple native methods are the same up to the first colon and would have conflicting JavaScript names.
    
+
    
+
    The CalendarManager module is instantiated on the Objective-C side using a [CalendarManager new] call. The return type of bridge methods is always void. React Native bridge is asynchronous, so the only way to pass a result to JavaScript is by using callbacks or emitting events (see below).
    
+
    Argument Types
    
+
    RCT_EXPORT_METHOD supports all standard JSON object types, such as:
    
+
      
+
    • string (NSString)
      • 
+
    • number (NSInteger, float, double, CGFloat, NSNumber)
      • 
+
    • boolean (BOOL, NSNumber)
      • 
+
    • array (NSArray) of any types from this list
      • 
+
    • object (NSDictionary) with string keys and values of any type from this list
      • 
+
    • function (RCTResponseSenderBlock)
      • 
+
    
+
    But it also works with any type that is supported by the RCTConvert class (see RCTConvert for details). The RCTConvert helper functions all accept a JSON value as input and map it to a native Objective-C type or class.
    
+
    In our CalendarManager example, we need to pass the event date to the native method. We can't send JavaScript Date objects over the bridge, so we need to convert the date to a string or number. We could write our native function like this:
    
+
    RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location date:(nonnull NSNumber *)secondsSinceUnixEpoch)
+{
+  NSDate *date = [RCTConvert NSDate:secondsSinceUnixEpoch];
+}
+
    
+
    or like this:
    
+
    RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location date:(NSString *)ISO8601DateString)
+{
+  NSDate *date = [RCTConvert NSDate:ISO8601DateString];
+}
+
    
+
    But by using the automatic type conversion feature, we can skip the manual conversion step completely, and just write:
    
+
    RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location date:(NSDate *)date)
+{
+  // Date is ready to use!
+}
+
    
+
    You would then call this from JavaScript by using either:
    
+
    CalendarManager.addEvent(
+  'Birthday Party',
+  '4 Privet Drive, Surrey',
+  date.getTime(),
+); // passing date as number of milliseconds since Unix epoch
+
    
+
    or
    
+
    CalendarManager.addEvent(
+  'Birthday Party',
+  '4 Privet Drive, Surrey',
+  date.toISOString(),
+); // passing date as ISO-8601 string
+
    
+
    And both values would get converted correctly to the native NSDate. A bad value, like an Array, would generate a helpful "RedBox" error message.
    
+
    As CalendarManager.addEvent method gets more and more complex, the number of arguments will grow. Some of them might be optional. In this case it's worth considering changing the API a little bit to accept a dictionary of event attributes, like this:
    
+
    #import <React/RCTConvert.h>
+
+RCT_EXPORT_METHOD(addEvent:(NSString *)name details:(NSDictionary *)details)
+{
+  NSString *location = [RCTConvert NSString:details[@"location"]];
+  NSDate *time = [RCTConvert NSDate:details[@"time"]];
+  ...
+}
+
    
+
    and call it from JavaScript:
    
+
    CalendarManager.addEvent('Birthday Party', {
+  location: '4 Privet Drive, Surrey',
+  time: date.getTime(),
+  description: '...',
+});
+
    
+
    
+
    NOTE: About array and map
    
+
    Objective-C doesn't provide any guarantees about the types of values in these structures. Your native module might expect an array of strings, but if JavaScript calls your method with an array containing numbers and strings, you'll get an NSArray containing a mix of NSNumber and NSString. For arrays, RCTConvert provides some typed collections you can use in your method declaration, such as NSStringArray, or UIColorArray. For maps, it is the developer's responsibility to check the value types individually by manually calling RCTConvert helper methods.
    
+
    
+
    Callbacks
    
+
    
+
    WARNING
    
+
    This section is more experimental than others because we don't have a solid set of best practices around callbacks yet.
    
+
    
+
    Native modules also supports a special kind of argument- a callback. In most cases it is used to provide the function call result to JavaScript.
    
+
    RCT_EXPORT_METHOD(findEvents:(RCTResponseSenderBlock)callback)
+{
+  NSArray *events = ...
+  callback(@[[NSNull null], events]);
+}
+
    
+
    RCTResponseSenderBlock accepts only one argument - an array of parameters to pass to the JavaScript callback. In this case we use Node's convention to make the first parameter an error object (usually null when there is no error) and the rest are the results of the function.
    
+
    CalendarManager.findEvents((error, events) => {
+  if (error) {
+    console.error(error);
+  } else {
+    this.setState({events: events});
+  }
+});
+
    
+
    A native module should invoke its callback exactly once. It's okay to store the callback and invoke it later. This pattern is often used to wrap iOS APIs that require delegates - see RCTAlertManager for an example. If the callback is never invoked, some memory is leaked. If both onSuccess and onFail callbacks are passed, you should only invoke one of them.
    
+
    If you want to pass error-like objects to JavaScript, use RCTMakeError from RCTUtils.h. Right now this just passes an Error-shaped dictionary to JavaScript, but we would like to automatically generate real JavaScript Error objects in the future.
    
+
    Promises
    
+
    Native modules can also fulfill a promise, which can simplify your code, especially when using ES2016's async/await syntax. When the last parameters of a bridged native method are an RCTPromiseResolveBlock and RCTPromiseRejectBlock, its corresponding JS method will return a JS Promise object.
    
+
    Refactoring the above code to use a promise instead of callbacks looks like this:
    
+
    RCT_REMAP_METHOD(findEvents,
+                 findEventsWithResolver:(RCTPromiseResolveBlock)resolve
+                 rejecter:(RCTPromiseRejectBlock)reject)
+{
+  NSArray *events = ...
+  if (events) {
+    resolve(events);
+  } else {
+    NSError *error = ...
+    reject(@"no_events", @"There were no events", error);
+  }
+}
+
    
+
    The JavaScript counterpart of this method returns a Promise. This means you can use the await keyword within an async function to call it and wait for its result:
    
+
    async function updateEvents() {
+  try {
+    var events = await CalendarManager.findEvents();
+
+    this.setState({events});
+  } catch (e) {
+    console.error(e);
+  }
+}
+
+updateEvents();
+
    
+
    Threading
    
+
    The native module should not have any assumptions about what thread it is being called on. React Native invokes native modules methods on a separate serial GCD queue, but this is an implementation detail and might change. The - (dispatch_queue_t)methodQueue method allows the native module to specify which queue its methods should be run on. For example, if it needs to use a main-thread-only iOS API, it should specify this via:
    
+
    - (dispatch_queue_t)methodQueue
+{
+  return dispatch_get_main_queue();
+}
+
    
+
    Similarly, if an operation may take a long time to complete, the native module should not block and can specify it's own queue to run operations on. For example, the RCTAsyncLocalStorage module creates its own queue so the React queue isn't blocked waiting on potentially slow disk access:
    
+
    - (dispatch_queue_t)methodQueue
+{
+  return dispatch_queue_create("com.facebook.React.AsyncLocalStorageQueue", DISPATCH_QUEUE_SERIAL);
+}
+
    
+
    The specified methodQueue will be shared by all of the methods in your module. If just one of your methods is long-running (or needs to be run on a different queue than the others for some reason), you can use dispatch_async inside the method to perform that particular method's code on another queue, without affecting the others:
    
+
    RCT_EXPORT_METHOD(doSomethingExpensive:(NSString *)param callback:(RCTResponseSenderBlock)callback)
+{
+  dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
+    // Call long-running code on background thread
+    ...
+    // You can invoke callback from any thread/queue
+    callback(@[...]);
+  });
+}
+
    
+
    
+
    NOTE: Sharing dispatch queues between modules
    
+
    The methodQueue method will be called once when the module is initialized, and then retained by the bridge, so there is no need to retain the queue yourself, unless you wish to make use of it within your module. However, if you wish to share the same queue between multiple modules then you will need to ensure that you retain and return the same queue instance for each of them; merely returning a queue of the same name for each won't work.
    
+
    
+
    Dependency Injection
    
+
    The bridge initializes any registered RCTBridgeModules automatically, however you may wish to instantiate your own module instances (so you may inject dependencies, for example).
    
+
    You can do this by creating a class that implements the RCTBridgeDelegate Protocol, initializing an RCTBridge with the delegate as an argument and initialising a RCTRootView with the initialized bridge.
    
+
    id<RCTBridgeDelegate> moduleInitialiser = [[classThatImplementsRCTBridgeDelegate alloc] init];
+
+RCTBridge *bridge = [[RCTBridge alloc] initWithDelegate:moduleInitialiser launchOptions:nil];
+
+RCTRootView *rootView = [[RCTRootView alloc]
+                        initWithBridge:bridge
+                            moduleName:kModuleName
+                     initialProperties:nil];
+
    
+
    Exporting Constants
    
+
    A native module can export constants that are immediately available to JavaScript at runtime. This is useful for communicating static data that would otherwise require a round-trip through the bridge.
    
+
    - (NSDictionary *)constantsToExport
+{
+  return @{ @"firstDayOfTheWeek": @"Monday" };
+}
+
    
+
    JavaScript can use this value right away, synchronously:
    
+
    console.log(CalendarManager.firstDayOfTheWeek);
+
    
+
    Note that the constants are exported only at initialization time, so if you change constantsToExport values at runtime it won't affect the JavaScript environment.
    
+
    Enum Constants
    
+
    Enums that are defined via NS_ENUM cannot be used as method arguments without first extending RCTConvert.
    
+
    In order to export the following NS_ENUM definition:
    
+
    typedef NS_ENUM(NSInteger, UIStatusBarAnimation) {
+    UIStatusBarAnimationNone,
+    UIStatusBarAnimationFade,
+    UIStatusBarAnimationSlide,
+};
+
    
+
    You must create a class extension of RCTConvert like so:
    
+
    @implementation RCTConvert (StatusBarAnimation)
+  RCT_ENUM_CONVERTER(UIStatusBarAnimation, (@{ @"statusBarAnimationNone" : @(UIStatusBarAnimationNone),
+                                               @"statusBarAnimationFade" : @(UIStatusBarAnimationFade),
+                                               @"statusBarAnimationSlide" : @(UIStatusBarAnimationSlide)}),
+                      UIStatusBarAnimationNone, integerValue)
+@end
+
    
+
    You can then define methods and export your enum constants like this:
    
+
    - (NSDictionary *)constantsToExport
+{
+  return @{ @"statusBarAnimationNone" : @(UIStatusBarAnimationNone),
+            @"statusBarAnimationFade" : @(UIStatusBarAnimationFade),
+            @"statusBarAnimationSlide" : @(UIStatusBarAnimationSlide) };
+};
+
+RCT_EXPORT_METHOD(updateStatusBarAnimation:(UIStatusBarAnimation)animation
+                                completion:(RCTResponseSenderBlock)callback)
+
    
+
    Your enum will then be automatically unwrapped using the selector provided (integerValue in the above example) before being passed to your exported method.
    
+
    Sending Events to JavaScript
    
+
    The native module can signal events to JavaScript without being invoked directly. The preferred way to do this is to subclass RCTEventEmitter, implement supportedEvents and call self sendEventWithName:
    
+
    // CalendarManager.h
+#import <React/RCTBridgeModule.h>
+#import <React/RCTEventEmitter.h>
+
+@interface CalendarManager : RCTEventEmitter <RCTBridgeModule>
+
+@end
+
    
+
    // CalendarManager.m
+#import "CalendarManager.h"
+
+@implementation CalendarManager
+
+RCT_EXPORT_MODULE();
+
+- (NSArray<NSString *> *)supportedEvents
+{
+  return @[@"EventReminder"];
+}
+
+- (void)calendarEventReminderReceived:(NSNotification *)notification
+{
+  NSString *eventName = notification.userInfo[@"name"];
+  [self sendEventWithName:@"EventReminder" body:@{@"name": eventName}];
+}
+
+@end
+
    
+
    JavaScript code can subscribe to these events by creating a new NativeEventEmitter instance around your module.
    
+
    import { NativeEventEmitter, NativeModules } from 'react-native';
+const { CalendarManager } = NativeModules;
+
+const calendarManagerEmitter = new NativeEventEmitter(CalendarManager);
+
+const subscription = calendarManagerEmitter.addListener(
+  'EventReminder',
+  (reminder) => console.log(reminder.name)
+);
+...
+// Don't forget to unsubscribe, typically in componentWillUnmount
+subscription.remove();
+
    
+
    For more examples of sending events to JavaScript, see RCTLocationObserver.
    
+
    Optimizing for zero listeners
    
+
    You will receive a warning if you expend resources unnecessarily by emitting an event while there are no listeners. To avoid this, and to optimize your module's workload (e.g. by unsubscribing from upstream notifications or pausing background tasks), you can override startObserving and stopObserving in your RCTEventEmitter subclass.
    
+
    @implementation CalendarManager
+{
+  bool hasListeners;
+}
+
+// Will be called when this module's first listener is added.
+-(void)startObserving {
+    hasListeners = YES;
+    // Set up any upstream listeners or background tasks as necessary
+}
+
+// Will be called when this module's last listener is removed, or on dealloc.
+-(void)stopObserving {
+    hasListeners = NO;
+    // Remove upstream listeners, stop unnecessary background tasks
+}
+
+- (void)calendarEventReminderReceived:(NSNotification *)notification
+{
+  NSString *eventName = notification.userInfo[@"name"];
+  if (hasListeners) { // Only send events if anyone is listening
+    [self sendEventWithName:@"EventReminder" body:@{@"name": eventName}];
+  }
+}
+
    
+
    Exporting Swift
    
+
    Swift doesn't have support for macros so exposing it to React Native requires a bit more setup but works relatively the same.
    
+
    Let's say we have the same CalendarManager but as a Swift class:
    
+
    // CalendarManager.swift
+
+@objc(CalendarManager)
+class CalendarManager: NSObject {
+
+  @objc(addEvent:location:date:)
+  func addEvent(name: String, location: String, date: NSNumber) -> Void {
+    // Date is ready to use!
+  }
+
+  @objc
+  func constantsToExport() -> [String: Any]! {
+    return ["someKey": "someValue"]
+  }
+
+}
+
    
+
    
+
    NOTE: It is important to use the @objc modifiers to ensure the class and functions are exported properly to the Objective-C runtime.
    
+
    
+
    Then create a private implementation file that will register the required information with the React Native bridge:
    
+
    // CalendarManagerBridge.m
+#import <React/RCTBridgeModule.h>
+
+@interface RCT_EXTERN_MODULE(CalendarManager, NSObject)
+
+RCT_EXTERN_METHOD(addEvent:(NSString *)name location:(NSString *)location date:(nonnull NSNumber *)date)
+
+@end
+
    
+
    For those of you new to Swift and Objective-C, whenever you mix the two languages in an iOS project, you will also need an additional bridging file, known as a bridging header, to expose the Objective-C files to Swift. Xcode will offer to create this header file for you if you add your Swift file to your app through the Xcode File>New File menu option. You will need to import RCTBridgeModule.h in this header file.
    
+
    // CalendarManager-Bridging-Header.h
+#import <React/RCTBridgeModule.h>
+
    
+
    You can also use RCT_EXTERN_REMAP_MODULE and _RCT_EXTERN_REMAP_METHOD to alter the JavaScript name of the module or methods you are exporting. For more information see RCTBridgeModule.
    
+
    
+
    Important when making third party modules: Static libraries with Swift are only supported in Xcode 9 and later. In order for the Xcode project to build when you use Swift in the iOS static library you include in the module, your main app project must contain Swift code and a bridging header itself. If your app project does not contain any Swift code, a workaround can be a single empty .swift file and an empty bridging header.

    Native Modules Setup
    Native modules are usually distributed as npm packages, except that on top of the usual Javascript they will include some native code per platform. To understand more about npm packages you may find this guide useful.
    
+
    To get set up with the basic project structure for a native module we will use a third party tool react-native-create-library. You can go ahead further and dive deep into how that library works, for our needs we will just need:
    
+
    $ npm install -g react-native-create-library
+$ react-native-create-library MyLibrary
+
    
+
    Where MyLibrary is the name you would like for the new module. After doing this you will navigate into MyLibrary folder and install the npm package to be locally available for your computer by doing:
    
+
    $ npm install
+
    
+
    After this is done you can go to your main react app folder (which you created by doing react-native init MyApp)
    
+
      
+
    • add your newly created module as a dependency in your package.json
      • 
+
    • run npm install to bring it along from your local npm repository.
      • 
+
    
+
    After this, you will be able to continue to native-modules-ios or native-module-android to add in some code. Make sure to read the README.md within your MyLibrary Directory for platform-specific instructions on how to include the project.

+Navigating Between Screens · React Native

    Edit
    Navigating Between Screens
    Mobile apps are rarely made up of a single screen. Managing the presentation of, and transition between, multiple screens is typically handled by what is known as a navigator.
    
+
    This guide covers the various navigation components available in React Native. If you are just getting started with navigation, you will probably want to use React Navigation. React Navigation provides an easy to use navigation solution, with the ability to present common stack navigation and tabbed navigation patterns on both iOS and Android.
    
+
    If you'd like to achieve a native look and feel on both iOS and Android, or you're integrating React Native into an app that already manages navigation natively, the following library provides native navigation on both platforms: react-native-navigation.
    
+
    React Navigation
    
+
    The community solution to navigation is a standalone library that allows developers to set up the screens of an app with just a few lines of code.
    
+
    The first step is to install in your project:
    
+
    npm install --save react-navigation
+
    
+
    Then you can quickly create an app with a home screen and a profile screen:
    
+
    import {createStackNavigator, createAppContainer} from 'react-navigation';
+
+const MainNavigator = createStackNavigator({
+  Home: {screen: HomeScreen},
+  Profile: {screen: ProfileScreen},
+});
+
+const App = createAppContainer(MainNavigator);
+
+export default App;
+
    
+
    Each screen component can set navigation options such as the header title. It can use action creators on the navigation prop to link to other screens:
    
+
    class HomeScreen extends React.Component {
+  static navigationOptions = {
+    title: 'Welcome',
+  };
+  render() {
+    const {navigate} = this.props.navigation;
+    return (
+      <Button
+        title="Go to Jane's profile"
+        onPress={() => navigate('Profile', {name: 'Jane'})}
+      />
+    );
+  }
+}
+
    
+
    React Navigation routers make it easy to override navigation logic. Because routers can be nested inside each other, developers can override navigation logic for one area of the app without making widespread changes.
    
+
    The views in React Navigation use native components and the Animated library to deliver 60fps animations that are run on the native thread. Plus, the animations and gestures can be easily customized.
    
+
    For a complete intro to React Navigation, follow the React Navigation Getting Started Guide, or browse other docs such as the Intro to Navigators.

+NavigatorIOS · React Native
    0.58
    Edit
    NavigatorIOS
    NavigatorIOS is a wrapper around UINavigationController, enabling you to implement a navigation stack. It works exactly the same as it would on a native app using UINavigationController, providing the same animations and behavior from UIKit.
    
+
    As the name implies, it is only available on iOS. Take a look at React Navigation for a cross-platform solution in JavaScript, or check out either of these components for native solutions: native-navigation, react-native-navigation.
    
+
    To set up the navigator, provide the initialRoute prop with a route object. A route object is used to describe each scene that your app navigates to. initialRoute represents the first route in your navigator.
    
+
    import PropTypes from 'prop-types';
+import React, {Component} from 'react';
+import {NavigatorIOS, Text, TouchableHighlight, View} from 'react-native';
+
+export default class NavigatorIOSApp extends Component {
+  render() {
+    return (
+      <NavigatorIOS
+        initialRoute={{
+          component: MyScene,
+          title: 'My Initial Scene',
+        }}
+        style={{flex: 1}}
+      />
+    );
+  }
+}
+
+class MyScene extends Component {
+  static propTypes = {
+    title: PropTypes.string.isRequired,
+    navigator: PropTypes.object.isRequired,
+  };
+
+  _onForward = () => {
+    this.props.navigator.push({
+      title: 'Scene',
+    });
+  };
+
+  render() {
+    return (
+      <View>
+        <Text>Current Scene: {this.props.title}</Text>
+        <TouchableHighlight onPress={this._onForward}>
+          <Text>Tap me to load the next scene</Text>
+        </TouchableHighlight>
+      </View>
+    );
+  }
+}
+
    
+
    In this code, the navigator renders the component specified in initialRoute, which in this case is MyScene. This component will receive a route prop and a navigator prop representing the navigator. The navigator's navigation bar will render the title for the current scene, "My Initial Scene".
    
+
    You can optionally pass in a passProps property to your initialRoute. NavigatorIOS passes this in as props to the rendered component:
    
+
    initialRoute={{
+  component: MyScene,
+  title: 'My Initial Scene',
+  passProps: { myProp: 'foo' }
+}}
+
    
+
    You can then access the props passed in via {this.props.myProp}.
    
+
    Handling Navigation
    
+
    To trigger navigation functionality such as pushing or popping a view, you have access to a navigator object. The object is passed in as a prop to any component that is rendered by NavigatorIOS. You can then call the relevant methods to perform the navigation action you need:
    
+
    class MyView extends Component {
+  _handleBackPress() {
+    this.props.navigator.pop();
+  }
+
+  _handleNextPress(nextRoute) {
+    this.props.navigator.push(nextRoute);
+  }
+
+  render() {
+    const nextRoute = {
+      component: MyView,
+      title: 'Bar That',
+      passProps: {myProp: 'bar'},
+    };
+    return (
+      <TouchableHighlight onPress={() => this._handleNextPress(nextRoute)}>
+        <Text style={{marginTop: 200, alignSelf: 'center'}}>
+          See you on the other nav {this.props.myProp}!
+        </Text>
+      </TouchableHighlight>
+    );
+  }
+}
+
    
+
    You can also trigger navigator functionality from the NavigatorIOS component:
    
+
    class NavvyIOS extends Component {
+  _handleNavigationRequest() {
+    this.refs.nav.push({
+      component: MyView,
+      title: 'Genius',
+      passProps: {myProp: 'genius'},
+    });
+  }
+
+  render() {
+    return (
+      <NavigatorIOS
+        ref="nav"
+        initialRoute={{
+          component: MyView,
+          title: 'Foo This',
+          passProps: {myProp: 'foo'},
+          rightButtonTitle: 'Add',
+          onRightButtonPress: () => this._handleNavigationRequest(),
+        }}
+        style={{flex: 1}}
+      />
+    );
+  }
+}
+
    
+
    The code above adds a _handleNavigationRequest private method that is invoked from the NavigatorIOS component when the right navigation bar item is pressed. To get access to the navigator functionality, a reference to it is saved in the ref prop and later referenced to push a new scene into the navigation stack.
    
+
    Navigation Bar Configuration
    
+
    Props passed to NavigatorIOS will set the default configuration for the navigation bar. Props passed as properties to a route object will set the configuration for that route's navigation bar, overriding any props passed to the NavigatorIOS component.
    
+
    _handleNavigationRequest() {
+  this.refs.nav.push({
+    //...
+    passProps: { myProp: 'genius' },
+    barTintColor: '#996699',
+  });
+}
+
+render() {
+  return (
+    <NavigatorIOS
+      //...
+      style={{flex: 1}}
+      barTintColor='#ffffcc'
+    />
+  );
+}
+
    
+
    In the example above the navigation bar color is changed when the new route is pushed.

    TypeRequired
    object: {component: function,title: string,titleImage: Image.propTypes.source,passProps: object,backButtonIcon: Image.propTypes.source,backButtonTitle: string,leftButtonIcon: Image.propTypes.source,leftButtonTitle: string,leftButtonSystemIcon: Object.keys(SystemIcons),onLeftButtonPress: function,rightButtonIcon: Image.propTypes.source,rightButtonTitle: string,rightButtonSystemIcon: Object.keys(SystemIcons),onRightButtonPress: function,wrapperStyle: View.style,navigationBarHidden: bool,shadowHidden: bool,tintColor: string,barTintColor: string,barStyle: enum('default', 'black'),titleTextColor: string,translucent: bool}Yes
    
+
    
+
    barStyle
    
+
    The style of the navigation bar. Supported values are 'default', 'black'. Use 'black' instead of setting barTintColor to black. This produces a navigation bar with the native iOS style with higher translucency.
    
+
+
+
+
+
+
+
+
    TypeRequired
    enum('default', 'black')No

    TypeRequired
    stringNo
    
+
    
+
    interactivePopGestureEnabled
    
+
    Boolean value that indicates whether the interactive pop gesture is enabled. This is useful for enabling/disabling the back swipe navigation gesture.
    
+
    If this prop is not provided, the default behavior is for the back swipe gesture to be enabled when the navigation bar is shown and disabled when the navigation bar is hidden. Once you've provided the interactivePopGestureEnabled prop, you can never restore the default behavior.
    
+
+
+
+
+
+
+
+
    TypeRequired
    boolNo
    
+
    
+
    itemWrapperStyle
    
+
    The default wrapper style for components in the navigator. A common use case is to set the backgroundColor for every scene.
    
+
+
+
+
+
+
+
+
    TypeRequired
    View.styleNo
    
+
    
+
    navigationBarHidden
    
+
    Boolean value that indicates whether the navigation bar is hidden by default.
    
+
+
+
+
+
+
+
+
    TypeRequired
    boolNo
    
+
    
+
    shadowHidden
    
+
    Boolean value that indicates whether to hide the 1px hairline shadow by default.

+
+
+
+
+
+
    TypeRequired
    stringNo
    
+
    
+
    titleTextColor
    
+
    The default text color of the navigation bar title.
    
+
+
+
+
+
+
+
+
    TypeRequired
    stringNo
    
+
    
+
    translucent
    
+
    Boolean value that indicates whether the navigation bar is translucent by default. When true any screens loaded within the navigator will sit below the status bar and underneath the navigation bar. To have screens render below the navigation bar set to false.
    
+
+
+
+
+
+
+
+
    TypeRequired
    boolNo
    
+

    NavigatorIOS
    NavigatorIOS is a wrapper around UINavigationController, enabling you to implement a navigation stack. It works exactly the same as it would on a native app using UINavigationController, providing the same animations and behavior from UIKit.
    
+
    As the name implies, it is only available on iOS. Take a look at React Navigation for a cross-platform solution in JavaScript, or check out either of these components for native solutions: native-navigation, react-native-navigation.
    
+
    To set up the navigator, provide the initialRoute prop with a route object. A route object is used to describe each scene that your app navigates to. initialRoute represents the first route in your navigator.
    
+
    import PropTypes from 'prop-types';
+import React, {Component} from 'react';
+import {NavigatorIOS, Text, TouchableHighlight, View} from 'react-native';
+
+export default class NavigatorIOSApp extends Component {
+  render() {
+    return (
+      <NavigatorIOS
+        initialRoute={{
+          component: MyScene,
+          title: 'My Initial Scene',
+        }}
+        style={{flex: 1}}
+      />
+    );
+  }
+}
+
+class MyScene extends Component {
+  static propTypes = {
+    title: PropTypes.string.isRequired,
+    navigator: PropTypes.object.isRequired,
+  };
+
+  _onForward = () => {
+    this.props.navigator.push({
+      title: 'Scene',
+    });
+  };
+
+  render() {
+    return (
+      <View>
+        <Text>Current Scene: {this.props.title}</Text>
+        <TouchableHighlight onPress={this._onForward}>
+          <Text>Tap me to load the next scene</Text>
+        </TouchableHighlight>
+      </View>
+    );
+  }
+}
+
    
+
    In this code, the navigator renders the component specified in initialRoute, which in this case is MyScene. This component will receive a route prop and a navigator prop representing the navigator. The navigator's navigation bar will render the title for the current scene, "My Initial Scene".
    
+
    You can optionally pass in a passProps property to your initialRoute. NavigatorIOS passes this in as props to the rendered component:
    
+
    initialRoute={{
+  component: MyScene,
+  title: 'My Initial Scene',
+  passProps: { myProp: 'foo' }
+}}
+
    
+
    You can then access the props passed in via {this.props.myProp}.
    
+
    Handling Navigation
    
+
    To trigger navigation functionality such as pushing or popping a view, you have access to a navigator object. The object is passed in as a prop to any component that is rendered by NavigatorIOS. You can then call the relevant methods to perform the navigation action you need:
    
+
    class MyView extends Component {
+  _handleBackPress() {
+    this.props.navigator.pop();
+  }
+
+  _handleNextPress(nextRoute) {
+    this.props.navigator.push(nextRoute);
+  }
+
+  render() {
+    const nextRoute = {
+      component: MyView,
+      title: 'Bar That',
+      passProps: {myProp: 'bar'},
+    };
+    return (
+      <TouchableHighlight onPress={() => this._handleNextPress(nextRoute)}>
+        <Text style={{marginTop: 200, alignSelf: 'center'}}>
+          See you on the other nav {this.props.myProp}!
+        </Text>
+      </TouchableHighlight>
+    );
+  }
+}
+
    
+
    You can also trigger navigator functionality from the NavigatorIOS component:
    
+
    class NavvyIOS extends Component {
+  _handleNavigationRequest() {
+    this.refs.nav.push({
+      component: MyView,
+      title: 'Genius',
+      passProps: {myProp: 'genius'},
+    });
+  }
+
+  render() {
+    return (
+      <NavigatorIOS
+        ref="nav"
+        initialRoute={{
+          component: MyView,
+          title: 'Foo This',
+          passProps: {myProp: 'foo'},
+          rightButtonTitle: 'Add',
+          onRightButtonPress: () => this._handleNavigationRequest(),
+        }}
+        style={{flex: 1}}
+      />
+    );
+  }
+}
+
    
+
    The code above adds a _handleNavigationRequest private method that is invoked from the NavigatorIOS component when the right navigation bar item is pressed. To get access to the navigator functionality, a reference to it is saved in the ref prop and later referenced to push a new scene into the navigation stack.
    
+
    Navigation Bar Configuration
    
+
    Props passed to NavigatorIOS will set the default configuration for the navigation bar. Props passed as properties to a route object will set the configuration for that route's navigation bar, overriding any props passed to the NavigatorIOS component.
    
+
    _handleNavigationRequest() {
+  this.refs.nav.push({
+    //...
+    passProps: { myProp: 'genius' },
+    barTintColor: '#996699',
+  });
+}
+
+render() {
+  return (
+    <NavigatorIOS
+      //...
+      style={{flex: 1}}
+      barTintColor='#ffffcc'
+    />
+  );
+}
+
    
+
    In the example above the navigation bar color is changed when the new route is pushed.

    initialRoute
    
+
    NavigatorIOS uses route objects to identify child views, their props, and navigation bar configuration. Navigation operations such as push operations expect routes to look like this the initialRoute.

    Edit
    Networking
    Many mobile apps need to load resources from a remote URL. You may want to make a POST request to a REST API, or you may simply need to fetch a chunk of static content from another server.
    
+
    Using Fetch
    
+
    React Native provides the Fetch API for your networking needs. Fetch will seem familiar if you have used XMLHttpRequest or other networking APIs before. You may refer to MDN's guide on Using Fetch for additional information.
    
+
    Making requests
    
+
    In order to fetch content from an arbitrary URL, just pass the URL to fetch:
    
+
    fetch('https://mywebsite.com/mydata.json');
+
    
+
    Fetch also takes an optional second argument that allows you to customize the HTTP request. You may want to specify additional headers, or make a POST request:
    
+
    fetch('https://mywebsite.com/endpoint/', {
+  method: 'POST',
+  headers: {
+    Accept: 'application/json',
+    'Content-Type': 'application/json',
+  },
+  body: JSON.stringify({
+    firstParam: 'yourValue',
+    secondParam: 'yourOtherValue',
+  }),
+});
+
    
+
    Take a look at the Fetch Request docs for a full list of properties.
    
+
    Handling the response
    
+
    The above examples show how you can make a request. In many cases, you will want to do something with the response.
    
+
    Networking is an inherently asynchronous operation. Fetch methods will return a Promise that makes it straightforward to write code that works in an asynchronous manner:
    
+
    function getMoviesFromApiAsync() {
+  return fetch('https://facebook.github.io/react-native/movies.json')
+    .then((response) => response.json())
+    .then((responseJson) => {
+      return responseJson.movies;
+    })
+    .catch((error) => {
+      console.error(error);
+    });
+}
+
    
+
    You can also use the proposed ES2017 async/await syntax in a React Native app:
    
+
    async function getMoviesFromApi() {
+  try {
+    let response = await fetch(
+      'https://facebook.github.io/react-native/movies.json',
+    );
+    let responseJson = await response.json();
+    return responseJson.movies;
+  } catch (error) {
+    console.error(error);
+  }
+}
+
    
+
    Don't forget to catch any errors that may be thrown by fetch, otherwise they will be dropped silently.
    
+
    
+
    By default, iOS will block any request that's not encrypted using SSL. If you need to fetch from a cleartext URL (one that begins with http) you will first need to add an App Transport Security exception. If you know ahead of time what domains you will need access to, it is more secure to add exceptions just for those domains; if the domains are not known until runtime you can disable ATS completely. Note however that from January 2017, Apple's App Store review will require reasonable justification for disabling ATS. See Apple's documentation for more information.
    
+
    
+
    Using Other Networking Libraries
    
+
    The XMLHttpRequest API is built in to React Native. This means that you can use third party libraries such as frisbee or axios that depend on it, or you can use the XMLHttpRequest API directly if you prefer.
    
+
    var request = new XMLHttpRequest();
+request.onreadystatechange = (e) => {
+  if (request.readyState !== 4) {
+    return;
+  }
+
+  if (request.status === 200) {
+    console.log('success', request.responseText);
+  } else {
+    console.warn('error');
+  }
+};
+
+request.open('GET', 'https://mywebsite.com/endpoint/');
+request.send();
+
    
+
    
+
    The security model for XMLHttpRequest is different than on web as there is no concept of CORS in native apps.
    
+
    
+
    WebSocket Support
    
+
    React Native also supports WebSockets, a protocol which provides full-duplex communication channels over a single TCP connection.
    
+
    var ws = new WebSocket('ws://host.com/path');
+
+ws.onopen = () => {
+  // connection opened
+  ws.send('something'); // send a message
+};
+
+ws.onmessage = (e) => {
+  // a message was received
+  console.log(e.data);
+};
+
+ws.onerror = (e) => {
+  // an error occurred
+  console.log(e.message);
+};
+
+ws.onclose = (e) => {
+  // connection closed
+  console.log(e.code, e.reason);
+};
+
    
+
    Known Issues with fetch and cookie based authentication
    
+
    The following options are currently not working with fetch
    
+
      
+
    • redirect:manual
      • 
+
    • credentials:omit
      •

    Out-of-Tree Platforms
    React Native is not just for Android and iOS - there are community-supported projects that bring it to other platforms, such as:
    
+
+
    Creating your own React Native platform
    
+
    Right now the process of creating a React Native platform from scratch is not very well documented - one of the goals of the upcoming re-architecture (Fabric) is to make maintaining a platform easier.
    
+
    Bundling
    
+
    As of React Native 0.57 you can now register your React Native platform with React Native's JavaScript bundler, Metro. This means you can pass --platform example to react-native bundle, and it will look for JavaScript files with the .example.js suffix.
    
+
    To register your platform with RNPM, your module's name must match one of these patterns:
    
+
      
+
    • react-native-example - It will search all top-level modules that start with react-native-
      • 
+
    • @org/react-native-example - It will search for modules that start with react-native- under any scope
      • 
+
    • @react-native-example/module - It will search in all modules under scopes with names starting with @react-native-
      • 
+
    
+
    You must also have an entry in your package.json like this:
    
+
    {
+  "rnpm": {
+    "haste": {
+      "providesModuleNodeModules": ["react-native-example"],
+      "platforms": ["example"]
+    }
+  }
+}
+
    
+
    "providesModuleNodeModules" is an array of modules that will get added to the Haste module search path, and "platforms" is an array of platform suffixes that will be added as valid platforms.

+PanResponder · React Native
    0.58
    Edit
    PanResponder
    PanResponder reconciles several touches into a single gesture. It makes single-touch gestures resilient to extra touches, and can be used to recognize simple multi-touch gestures.
    
+
    By default, PanResponder holds an InteractionManager handle to block long-running JS events from interrupting active gestures.
    
+
    It provides a predictable wrapper of the responder handlers provided by the gesture responder system. For each handler, it provides a new gestureState object alongside the native event object:
    
+
    onPanResponderMove: (event, gestureState) => {}
+
    
+
    A native event is a synthetic touch event with the following form:
    
+
      
+
    • nativeEvent
+
        
+
      • changedTouches - Array of all touch events that have changed since the last event
        • 
+
      • identifier - The ID of the touch
        • 
+
      • locationX - The X position of the touch, relative to the element
        • 
+
      • locationY - The Y position of the touch, relative to the element
        • 
+
      • pageX - The X position of the touch, relative to the root element
        • 
+
      • pageY - The Y position of the touch, relative to the root element
        • 
+
      • target - The node id of the element receiving the touch event
        • 
+
      • timestamp - A time identifier for the touch, useful for velocity calculation
        • 
+
      • touches - Array of all current touches on the screen
        • 
+
      • 
+
    
+
    A gestureState object has the following:
    
+
      
+
    • stateID - ID of the gestureState- persisted as long as there at least one touch on screen
      • 
+
    • moveX - the latest screen coordinates of the recently-moved touch
      • 
+
    • moveY - the latest screen coordinates of the recently-moved touch
      • 
+
    • x0 - the screen coordinates of the responder grant
      • 
+
    • y0 - the screen coordinates of the responder grant
      • 
+
    • dx - accumulated distance of the gesture since the touch started
      • 
+
    • dy - accumulated distance of the gesture since the touch started
      • 
+
    • vx - current velocity of the gesture
      • 
+
    • vy - current velocity of the gesture
      • 
+
    • numberActiveTouches - Number of touches currently on screen
      • 
+
    
+
    Basic Usage
    
+
    class ExampleComponent extends Component {
+  constructor(props) {
+    super(props);
+    this._panResponder = PanResponder.create({
+      // Ask to be the responder:
+      onStartShouldSetPanResponder: (evt, gestureState) => true,
+      onStartShouldSetPanResponderCapture: (evt, gestureState) => true,
+      onMoveShouldSetPanResponder: (evt, gestureState) => true,
+      onMoveShouldSetPanResponderCapture: (evt, gestureState) => true,
+
+      onPanResponderGrant: (evt, gestureState) => {
+        // The gesture has started. Show visual feedback so the user knows
+        // what is happening!
+        // gestureState.d{x,y} will be set to zero now
+      },
+      onPanResponderMove: (evt, gestureState) => {
+        // The most recent move distance is gestureState.move{X,Y}
+        // The accumulated gesture distance since becoming responder is
+        // gestureState.d{x,y}
+      },
+      onPanResponderTerminationRequest: (evt, gestureState) => true,
+      onPanResponderRelease: (evt, gestureState) => {
+        // The user has released all touches while this view is the
+        // responder. This typically means a gesture has succeeded
+      },
+      onPanResponderTerminate: (evt, gestureState) => {
+        // Another component has become the responder, so this gesture
+        // should be cancelled
+      },
+      onShouldBlockNativeResponder: (evt, gestureState) => {
+        // Returns whether this component should block native components from becoming the JS
+        // responder. Returns true by default. Is currently only supported on android.
+        return true;
+      },
+    });
+  }
+
+  render() {
+    return <View {...this._panResponder.panHandlers} />;
+  }
+}
+
    
+
    Working Example
    
+
    To see it in action, try the PanResponder example in RNTester
    
+
    Methods
    
+
+
    
+
    Reference
    
+
    Methods
    
+
    create()
    
+
    static create(config)
+
    
+
    @param {object} config Enhanced versions of all of the responder callbacks that provide not only the typical ResponderSyntheticEvent, but also the PanResponder gesture state. Simply replace the word Responder with PanResponder in each of the typical onResponder* callbacks. For example, the config object would look like:
    
+
      
+
    • onMoveShouldSetPanResponder: (e, gestureState) => {...}

    Be careful with onStartShould* callbacks. They only reflect updated gestureState for start/end events that bubble/capture to the Node. Once the node is the responder, you can rely on every start/end event being processed by the gesture and gestureState being updated accordingly. (numberActiveTouches) may not be totally accurate unless you are the responder.

+PanResponder · React Native
    0.58
    Edit
    PanResponder
    PanResponder reconciles several touches into a single gesture. It makes single-touch gestures resilient to extra touches, and can be used to recognize simple multi-touch gestures.
    
+
    By default, PanResponder holds an InteractionManager handle to block long-running JS events from interrupting active gestures.
    
+
    It provides a predictable wrapper of the responder handlers provided by the gesture responder system. For each handler, it provides a new gestureState object alongside the native event object:
    
+
    onPanResponderMove: (event, gestureState) => {}
+
    
+
    A native event is a synthetic touch event with the following form:
    
+
      
+
    • nativeEvent
+
        
+
      • changedTouches - Array of all touch events that have changed since the last event
        • 
+
      • identifier - The ID of the touch
        • 
+
      • locationX - The X position of the touch, relative to the element
        • 
+
      • locationY - The Y position of the touch, relative to the element
        • 
+
      • pageX - The X position of the touch, relative to the root element
        • 
+
      • pageY - The Y position of the touch, relative to the root element
        • 
+
      • target - The node id of the element receiving the touch event
        • 
+
      • timestamp - A time identifier for the touch, useful for velocity calculation
        • 
+
      • touches - Array of all current touches on the screen
        • 
+
      • 
+
    
+
    A gestureState object has the following:
    
+
      
+
    • stateID - ID of the gestureState- persisted as long as there at least one touch on screen
      • 
+
    • moveX - the latest screen coordinates of the recently-moved touch
      • 
+
    • moveY - the latest screen coordinates of the recently-moved touch
      • 
+
    • x0 - the screen coordinates of the responder grant
      • 
+
    • y0 - the screen coordinates of the responder grant
      • 
+
    • dx - accumulated distance of the gesture since the touch started
      • 
+
    • dy - accumulated distance of the gesture since the touch started
      • 
+
    • vx - current velocity of the gesture
      • 
+
    • vy - current velocity of the gesture
      • 
+
    • numberActiveTouches - Number of touches currently on screen
      • 
+
    
+
    Basic Usage
    
+
    class ExampleComponent extends Component {
+  constructor(props) {
+    super(props);
+    this._panResponder = PanResponder.create({
+      // Ask to be the responder:
+      onStartShouldSetPanResponder: (evt, gestureState) => true,
+      onStartShouldSetPanResponderCapture: (evt, gestureState) => true,
+      onMoveShouldSetPanResponder: (evt, gestureState) => true,
+      onMoveShouldSetPanResponderCapture: (evt, gestureState) => true,
+
+      onPanResponderGrant: (evt, gestureState) => {
+        // The gesture has started. Show visual feedback so the user knows
+        // what is happening!
+        // gestureState.d{x,y} will be set to zero now
+      },
+      onPanResponderMove: (evt, gestureState) => {
+        // The most recent move distance is gestureState.move{X,Y}
+        // The accumulated gesture distance since becoming responder is
+        // gestureState.d{x,y}
+      },
+      onPanResponderTerminationRequest: (evt, gestureState) => true,
+      onPanResponderRelease: (evt, gestureState) => {
+        // The user has released all touches while this view is the
+        // responder. This typically means a gesture has succeeded
+      },
+      onPanResponderTerminate: (evt, gestureState) => {
+        // Another component has become the responder, so this gesture
+        // should be cancelled
+      },
+      onShouldBlockNativeResponder: (evt, gestureState) => {
+        // Returns whether this component should block native components from becoming the JS
+        // responder. Returns true by default. Is currently only supported on android.
+        return true;
+      },
+    });
+  }
+
+  render() {
+    return <View {...this._panResponder.panHandlers} />;
+  }
+}
+
    
+
    Working Example
    
+
    To see it in action, try the PanResponder example in RNTester

    Reference
    
+
    Methods
    
+
    create()
    
+
    static create(config)
+
    
+
    @param {object} config Enhanced versions of all of the responder callbacks that provide not only the typical ResponderSyntheticEvent, but also the PanResponder gesture state. Simply replace the word Responder with PanResponder in each of the typical onResponder* callbacks. For example, the config object would look like:
    
+
      
+
    • onMoveShouldSetPanResponder: (e, gestureState) => {...}
      • 
+
    • onMoveShouldSetPanResponderCapture: (e, gestureState) => {...}
      • 
+
    • onStartShouldSetPanResponder: (e, gestureState) => {...}
      • 
+
    • onStartShouldSetPanResponderCapture: (e, gestureState) => {...}
      • 
+
    • onPanResponderReject: (e, gestureState) => {...}
      • 
+
    • onPanResponderGrant: (e, gestureState) => {...}
      • 
+
    • onPanResponderStart: (e, gestureState) => {...}
      • 
+
    • onPanResponderEnd: (e, gestureState) => {...}
      • 
+
    • onPanResponderRelease: (e, gestureState) => {...}
      • 
+
    • onPanResponderMove: (e, gestureState) => {...}
      • 
+
    • onPanResponderTerminate: (e, gestureState) => {...}
      • 
+
    • onPanResponderTerminationRequest: (e, gestureState) => {...}
      • 
+
    • onShouldBlockNativeResponder: (e, gestureState) => {...}
      • 
+
    
+
    In general, for events that have capture equivalents, we update the gestureState once in the capture phase and can use it in the bubble phase as well.
    
+
    Be careful with onStartShould* callbacks. They only reflect updated gestureState for start/end events that bubble/capture to the Node. Once the node is the responder, you can rely on every start/end event being processed by the gesture and gestureState being updated accordingly. (numberActiveTouches) may not be totally accurate unless you are the responder.

+Performance · React Native
    0.58
    Edit
    Performance
    A compelling reason for using React Native instead of WebView-based tools is to achieve 60 frames per second and a native look and feel to your apps. Where possible, we would like for React Native to do the right thing and help you to focus on your app instead of performance optimization, but there are areas where we're not quite there yet, and others where React Native (similar to writing native code directly) cannot possibly determine the best way to optimize for you and so manual intervention will be necessary. We try our best to deliver buttery-smooth UI performance by default, but sometimes that just isn't possible.
    
+
    This guide is intended to teach you some basics to help you to troubleshoot performance issues, as well as discuss common sources of problems and their suggested solutions.
    
+
    What you need to know about frames
    
+
    Your grandparents' generation called movies "moving pictures" for a reason: realistic motion in video is an illusion created by quickly changing static images at a consistent speed. We refer to each of these images as frames. The number of frames that is displayed each second has a direct impact on how smooth and ultimately life-like a video (or user interface) seems to be. iOS devices display 60 frames per second, which gives you and the UI system about 16.67ms to do all of the work needed to generate the static image (frame) that the user will see on the screen for that interval. If you are unable to do the work necessary to generate that frame within the allotted 16.67ms, then you will "drop a frame" and the UI will appear unresponsive.
    
+
    Now to confuse the matter a little bit, open up the developer menu in your app and toggle Show Perf Monitor. You will notice that there are two different frame rates.
    
+
    
+
    JS frame rate (JavaScript thread)
    
+
    For most React Native applications, your business logic will run on the JavaScript thread. This is where your React application lives, API calls are made, touch events are processed, etc... Updates to native-backed views are batched and sent over to the native side at the end of each iteration of the event loop, before the frame deadline (if all goes well). If the JavaScript thread is unresponsive for a frame, it will be considered a dropped frame. For example, if you were to call this.setState on the root component of a complex application and it resulted in re-rendering computationally expensive component subtrees, it's conceivable that this might take 200ms and result in 12 frames being dropped. Any animations controlled by JavaScript would appear to freeze during that time. If anything takes longer than 100ms, the user will feel it.
    
+
    This often happens during Navigator transitions: when you push a new route, the JavaScript thread needs to render all of the components necessary for the scene in order to send over the proper commands to the native side to create the backing views. It's common for the work being done here to take a few frames and cause jank because the transition is controlled by the JavaScript thread. Sometimes components will do additional work on componentDidMount, which might result in a second stutter in the transition.
    
+
    Another example is responding to touches: if you are doing work across multiple frames on the JavaScript thread, you might notice a delay in responding to TouchableOpacity, for example. This is because the JavaScript thread is busy and cannot process the raw touch events sent over from the main thread. As a result, TouchableOpacity cannot react to the touch events and command the native view to adjust its opacity.
    
+
    UI frame rate (main thread)
    
+
    Many people have noticed that performance of NavigatorIOS is better out of the box than Navigator. The reason for this is that the animations for the transitions are done entirely on the main thread, and so they are not interrupted by frame drops on the JavaScript thread.
    
+
    Similarly, you can happily scroll up and down through a ScrollView when the JavaScript thread is locked up because the ScrollView lives on the main thread. The scroll events are dispatched to the JS thread, but their receipt is not necessary for the scroll to occur.
    
+
    Common sources of performance problems
    
+
    Running in development mode (dev=true)
    
+
    JavaScript thread performance suffers greatly when running in dev mode. This is unavoidable: a lot more work needs to be done at runtime to provide you with good warnings and error messages, such as validating propTypes and various other assertions. Always make sure to test performance in release builds.
    
+
    Using console.log statements
    
+
    When running a bundled app, these statements can cause a big bottleneck in the JavaScript thread. This includes calls from debugging libraries such as redux-logger, so make sure to remove them before bundling. You can also use this babel plugin that removes all the console.* calls. You need to install it first with npm i babel-plugin-transform-remove-console --save-dev, and then edit the .babelrc file under your project directory like this:
    
+
    {
+  "env": {
+    "production": {
+      "plugins": ["transform-remove-console"]
+    }
+  }
+}
+
    
+
    This will automatically remove all console.* calls in the release (production) versions of your project.
    
+
    ListView initial rendering is too slow or scroll performance is bad for large lists
    
+
    Use the new FlatList or SectionList component instead. Besides simplifying the API, the new list components also have significant performance enhancements, the main one being nearly constant memory usage for any number of rows.
    
+
    If your FlatList is rendering slow, be sure that you've implemented getItemLayout to optimize rendering speed by skipping measurement of the rendered items.
    
+
    JS FPS plunges when re-rendering a view that hardly changes
    
+
    If you are using a ListView, you must provide a rowHasChanged function that can reduce a lot of work by quickly determining whether or not a row needs to be re-rendered. If you are using immutable data structures, this would be as simple as a reference equality check.
    
+
    Similarly, you can implement shouldComponentUpdate and indicate the exact conditions under which you would like the component to re-render. If you write pure components (where the return value of the render function is entirely dependent on props and state), you can leverage PureComponent to do this for you. Once again, immutable data structures are useful to keep this fast -- if you have to do a deep comparison of a large list of objects, it may be that re-rendering your entire component would be quicker, and it would certainly require less code.
    
+
    Dropping JS thread FPS because of doing a lot of work on the JavaScript thread at the same time
    
+
    "Slow Navigator transitions" is the most common manifestation of this, but there are other times this can happen. Using InteractionManager can be a good approach, but if the user experience cost is too high to delay work during an animation, then you might want to consider LayoutAnimation.
    
+
    The Animated API currently calculates each keyframe on-demand on the JavaScript thread unless you set useNativeDriver: true, while LayoutAnimation leverages Core Animation and is unaffected by JS thread and main thread frame drops.
    
+
    One case where I have used this is for animating in a modal (sliding down from top and fading in a translucent overlay) while initializing and perhaps receiving responses for several network requests, rendering the contents of the modal, and updating the view where the modal was opened from. See the Animations guide for more information about how to use LayoutAnimation.
    
+
    Caveats:
    
+
      
+
    • LayoutAnimation only works for fire-and-forget animations ("static" animations) -- if it must be interruptible, you will need to use Animated.
      • 
+
    
+
    Moving a view on the screen (scrolling, translating, rotating) drops UI thread FPS
    
+
    This is especially true when you have text with a transparent background positioned on top of an image, or any other situation where alpha compositing would be required to re-draw the view on each frame. You will find that enabling shouldRasterizeIOS or renderToHardwareTextureAndroid can help with this significantly.
    
+
    Be careful not to overuse this or your memory usage could go through the roof. Profile your performance and memory usage when using these props. If you don't plan to move a view anymore, turn this property off.
    
+
    Animating the size of an image drops UI thread FPS
    
+
    On iOS, each time you adjust the width or height of an Image component it is re-cropped and scaled from the original image. This can be very expensive, especially for large images. Instead, use the transform: [{scale}] style property to animate the size. An example of when you might do this is when you tap an image and zoom it in to full screen.
    
+
    My TouchableX view isn't very responsive
    
+
    Sometimes, if we do an action in the same frame that we are adjusting the opacity or highlight of a component that is responding to a touch, we won't see that effect until after the onPress function has returned. If onPress does a setState that results in a lot of work and a few frames dropped, this may occur. A solution to this is to wrap any action inside of your onPress handler in requestAnimationFrame:
    
+
    handleOnPress() {
+  // Always use TimerMixin with requestAnimationFrame, setTimeout and
+  // setInterval
+  this.requestAnimationFrame(() => {
+    this.doExpensiveAction();
+  });
+}
+
    
+
    Slow navigator transitions
    
+
    As mentioned above, Navigator animations are controlled by the JavaScript thread. Imagine the "push from right" scene transition: each frame, the new scene is moved from the right to left, starting offscreen (let's say at an x-offset of 320) and ultimately settling when the scene sits at an x-offset of
    
+
      
+
    1. Each frame during this transition, the JavaScript thread needs to send a new x-offset to the main thread. If the JavaScript thread is locked up, it cannot do this and so no update occurs on that frame and the animation stutters.
      2. 
+
    
+
    One solution to this is to allow for JavaScript-based animations to be offloaded to the main thread. If we were to do the same thing as in the above example with this approach, we might calculate a list of all x-offsets for the new scene when we are starting the transition and send them to the main thread to execute in an optimized way. Now that the JavaScript thread is freed of this responsibility, it's not a big deal if it drops a few frames while rendering the scene -- you probably won't even notice because you will be too distracted by the pretty transition.
    
+
    Solving this is one of the main goals behind the new React Navigation library. The views in React Navigation use native components and the Animated library to deliver 60 FPS animations that are run on the native thread.
    
+
    Profiling
    
+
    Use the built-in profiler to get detailed information about work done in the JavaScript thread and main thread side-by-side. Access it by selecting Perf Monitor from the Debug menu.
    
+
    For iOS, Instruments is an invaluable tool, and on Android you should learn to use systrace.
    
+
    But first, make sure that Development Mode is OFF! You should see __DEV__ === false, development-level warning are OFF, performance optimizations are ON in your application logs.
    
+
    Another way to profile JavaScript is to use the Chrome profiler while debugging. This won't give you accurate results as the code is running in Chrome but will give you a general idea of where bottlenecks might be. Run the profiler under Chrome's Performance tab. A flame graph will appear under User Timing. To view more details in tabular format, click at the Bottom Up tab below and then select DedicatedWorker Thread at the top left menu.
    
+
    Profiling Android UI Performance with systrace
    
+
    Android supports 10k+ different phones and is generalized to support software rendering: the framework architecture and need to generalize across many hardware targets unfortunately means you get less for free relative to iOS. But sometimes, there are things you can improve -- and many times it's not native code's fault at all!
    
+
    The first step for debugging this jank is to answer the fundamental question of where your time is being spent during each 16ms frame. For that, we'll be using a standard Android profiling tool called systrace.
    
+
    systrace is a standard Android marker-based profiling tool (and is installed when you install the Android platform-tools package). Profiled code blocks are surrounded by start/end markers which are then visualized in a colorful chart format. Both the Android SDK and React Native framework provide standard markers that you can visualize.
    
+
    1. Collecting a trace
    
+
    First, connect a device that exhibits the stuttering you want to investigate to your computer via USB and get it to the point right before the navigation/animation you want to profile. Run systrace as follows:
    
+
    $ <path_to_android_sdk>/platform-tools/systrace/systrace.py --time=10 -o trace.html sched gfx view -a <your_package_name>
+
    
+
    A quick breakdown of this command:
    
+
      
+
    • time is the length of time the trace will be collected in seconds
      • 
+
    • sched, gfx, and view are the android SDK tags (collections of markers) we care about: sched gives you information about what's running on each core of your phone, gfx gives you graphics info such as frame boundaries, and view gives you information about measure, layout, and draw passes
      • 
+
    • -a <your_package_name> enables app-specific markers, specifically the ones built into the React Native framework. your_package_name can be found in the AndroidManifest.xml of your app and looks like com.example.app
      • 
+
    
+
    Once the trace starts collecting, perform the animation or interaction you care about. At the end of the trace, systrace will give you a link to the trace which you can open in your browser.
    
+
    2. Reading the trace
    
+
    After opening the trace in your browser (preferably Chrome), you should see something like this:
    
+
    Example
    
+
    
+
    HINT: Use the WASD keys to strafe and zoom
    
+
    
+
    If your trace .html file isn't opening correctly, check your browser console for the following:
    
+
    ObjectObserveError
    
+
    Since Object.observe was deprecated in recent browsers, you may have to open the file from the Google Chrome Tracing tool. You can do so by:
    
+
      
+
    • Opening tab in chrome chrome://tracing
      • 
+
    • Selecting load
      • 
+
    • Selecting the html file generated from the previous command.
      • 
+
    
+
    
+
    Enable VSync highlighting
    
+
    Check this checkbox at the top right of the screen to highlight the 16ms frame boundaries:
    
+
    Enable VSync Highlighting
    
+
    You should see zebra stripes as in the screenshot above. If you don't, try profiling on a different device: Samsung has been known to have issues displaying vsyncs while the Nexus series is generally pretty reliable.
    
+
    
+
    3. Find your process
    
+
    Scroll until you see (part of) the name of your package. In this case, I was profiling com.facebook.adsmanager, which shows up as book.adsmanager because of silly thread name limits in the kernel.
    
+
    On the left side, you'll see a set of threads which correspond to the timeline rows on the right. There are a few threads we care about for our purposes: the UI thread (which has your package name or the name UI Thread), mqt_js, and mqt_native_modules. If you're running on Android 5+, we also care about the Render Thread.
    
+
      
+
    • UI Thread. This is where standard android measure/layout/draw happens. The thread name on the right will be your package name (in my case book.adsmanager) or UI Thread. The events that you see on this thread should look something like this and have to do with Choreographer, traversals, and DispatchUI:
      
+
      UI Thread Example
      • 
+
    • JS Thread. This is where JavaScript is executed. The thread name will be either mqt_js or <...> depending on how cooperative the kernel on your device is being. To identify it if it doesn't have a name, look for things like JSCall, Bridge.executeJSCall, etc:
      
+
      JS Thread Example
      • 
+
    • Native Modules Thread. This is where native module calls (e.g. the UIManager) are executed. The thread name will be either mqt_native_modules or <...>. To identify it in the latter case, look for things like NativeCall, callJavaModuleMethod, and onBatchComplete:
      
+
      Native Modules Thread Example
      • 
+
    • Bonus: Render Thread. If you're using Android L (5.0) and up, you will also have a render thread in your application. This thread generates the actual OpenGL commands used to draw your UI. The thread name will be either RenderThread or <...>. To identify it in the latter case, look for things like DrawFrame and queueBuffer:
      
+
      Render Thread Example
      • 
+
    
+
    Identifying a culprit
    
+
    A smooth animation should look something like the following:
    
+
    Smooth Animation
    
+
    Each change in color is a frame -- remember that in order to display a frame, all our UI work needs to be done by the end of that 16ms period. Notice that no thread is working close to the frame boundary. An application rendering like this is rendering at 60 FPS.
    
+
    If you noticed chop, however, you might see something like this:
    
+
    Choppy Animation from JS
    
+
    Notice that the JS thread is executing basically all the time, and across frame boundaries! This app is not rendering at 60 FPS. In this case, the problem lies in JS.
    
+
    You might also see something like this:
    
+
    Choppy Animation from UI
    
+
    In this case, the UI and render threads are the ones that have work crossing frame boundaries. The UI that we're trying to render on each frame is requiring too much work to be done. In this case, the problem lies in the native views being rendered.
    
+
    At this point, you'll have some very helpful information to inform your next steps.
    
+
    Resolving JavaScript issues
    
+
    If you identified a JS problem, look for clues in the specific JS that you're executing. In the scenario above, we see RCTEventEmitter being called multiple times per frame. Here's a zoom-in of the JS thread from the trace above:
    
+
    Too much JS
    
+
    This doesn't seem right. Why is it being called so often? Are they actually different events? The answers to these questions will probably depend on your product code. And many times, you'll want to look into shouldComponentUpdate.
    
+
    Resolving native UI Issues
    
+
    If you identified a native UI problem, there are usually two scenarios:
    
+
      
+
    1. the UI you're trying to draw each frame involves too much work on the GPU, or
      2. 
+
    2. You're constructing new UI during the animation/interaction (e.g. loading in new content during a scroll).
      3. 
+
    
+
    Too much GPU work
    
+
    In the first scenario, you'll see a trace that has the UI thread and/or Render Thread looking like this:
    
+
    Overloaded GPU
    
+
    Notice the long amount of time spent in DrawFrame that crosses frame boundaries. This is time spent waiting for the GPU to drain its command buffer from the previous frame.
    
+
    To mitigate this, you should:
    
+
      
+
    • investigate using renderToHardwareTextureAndroid for complex, static content that is being animated/transformed (e.g. the Navigator slide/alpha animations)
      • 
+
    • make sure that you are not using needsOffscreenAlphaCompositing, which is disabled by default, as it greatly increases the per-frame load on the GPU in most cases.
      • 
+
    
+
    If these don't help and you want to dig deeper into what the GPU is actually doing, you can check out Tracer for OpenGL ES.
    
+
    Creating new views on the UI thread
    
+
    In the second scenario, you'll see something more like this:
    
+
    Creating Views
    
+
    Notice that first the JS thread thinks for a bit, then you see some work done on the native modules thread, followed by an expensive traversal on the UI thread.
    
+
    There isn't an easy way to mitigate this unless you're able to postpone creating new UI until after the interaction, or you are able to simplify the UI you're creating. The react native team is working on an infrastructure level solution for this that will allow new UI to be created and configured off the main thread, allowing the interaction to continue smoothly.

    RAM bundles + inline requires
    
+
    If you have a large app you may want to consider the Random Access Modules (RAM) bundle format, and using inline requires. This is useful for apps that have a large number of screens which may not ever be opened during a typical usage of the app. Generally it is useful to apps that have large amounts of code that are not needed for a while after startup. For instance the app includes complicated profile screens or lesser used features, but most sessions only involve visiting the main screen of the app for updates. We can optimize the loading of the bundle by using the RAM format and requiring those features and screens inline (when they are actually used).
    
+
    Loading JavaScript
    
+
    Before react-native can execute JS code, that code must be loaded into memory and parsed. With a standard bundle if you load a 50mb bundle, all 50mb must be loaded and parsed before any of it can be executed. The optimization behind RAM bundles is that you can load only the portion of the 50mb that you actually need at startup, and progressively load more of the bundle as those sections are needed.
    
+
    Inline Requires
    
+
    Inline requires delay the requiring of a module or file until that file is actually needed. A basic example would look like this:
    
+
    VeryExpensive.js
    
+
    import React, { Component } from 'react';
+import { Text } from 'react-native';
+// ... import some very expensive modules
+
+// You may want to log at the file level to verify when this is happening
+console.log('VeryExpensive component loaded');
+
+export default class VeryExpensive extends Component {
+  // lots and lots of code
+  render() {
+    return <Text>Very Expensive Component</Text>;
+  }
+}
+
    
+
    Optimized.js
    
+
    import React, { Component } from 'react';
+import { TouchableOpacity, View, Text } from 'react-native';
+
+let VeryExpensive = null;
+
+export default class Optimized extends Component {
+  state = { needsExpensive: false };
+
+  didPress = () => {
+    if (VeryExpensive == null) {
+      VeryExpensive = require('./VeryExpensive').default;
+    }
+
+    this.setState(() => ({
+      needsExpensive: true,
+    }));
+  };
+
+  render() {
+    return (
+      <View style={{ marginTop: 20 }}>
+        <TouchableOpacity onPress={this.didPress}>
+          <Text>Load</Text>
+        </TouchableOpacity>
+        {this.state.needsExpensive ? <VeryExpensive /> : null}
+      </View>
+    );
+  }
+}
+
    
+
    Even without the RAM format, inline requires can lead to startup time improvements, because the code within VeryExpensive.js will only execute once it is required for the first time.
    
+
    Enable the RAM format
    
+
    On iOS using the RAM format will create a single indexed file that react native will load one module at a time. On Android, by default it will create a set of files for each module. You can force Android to create a single file, like iOS, but using multiple files can be more performant and requires less memory.
    
+
    Enable the RAM format in Xcode by editing the build phase "Bundle React Native code and images". Before ../node_modules/react-native/scripts/react-native-xcode.sh add export BUNDLE_COMMAND="ram-bundle":
    
+
    export BUNDLE_COMMAND="ram-bundle"
+export NODE_BINARY=node
+../node_modules/react-native/scripts/react-native-xcode.sh
+
    
+
    On Android enable the RAM format by editing your android/app/build.gradle file. Before the line apply from: "../../node_modules/react-native/react.gradle" add or amend the project.ext.react block:
    
+
    project.ext.react = [
+  bundleCommand: "ram-bundle",
+]
+
    
+
    Use the following lines on Android if you want to use a single indexed file:
    
+
    project.ext.react = [
+  bundleCommand: "ram-bundle",
+  extraPackagerArgs: ["--indexed-ram-bundle"]
+]
+
    
+
    Configure Preloading and Inline Requires
    
+
    Now that we have a RAM bundle, there is overhead for calling require. require now needs to send a message over the bridge when it encounters a module it has not loaded yet. This will impact startup the most, because that is where the largest number of require calls are likely to take place while the app loads the initial module. Luckily we can configure a portion of the modules to be preloaded. In order to do this, you will need to implement some form of inline require.
    
+
    Adding a packager config file
    
+
    Create a folder in your project called packager, and create a single file named config.js. Add the following:
    
+
    const config = {
+  transformer: {
+    getTransformOptions: () => {
+      return {
+        transform: { inlineRequires: true },
+      };
+    },
+  },
+};
+
+module.exports = config;
+
    
+
    In Xcode, in the build phase, include export BUNDLE_CONFIG="packager/config.js".
    
+
    export BUNDLE_COMMAND="ram-bundle"
+export BUNDLE_CONFIG="packager/config.js"
+export NODE_BINARY=node
+../node_modules/react-native/scripts/react-native-xcode.sh
+
    
+
    Edit your android/app/build.gradle file to include bundleConfig: "packager/config.js",.
    
+
    project.ext.react = [
+  bundleCommand: "ram-bundle",
+  bundleConfig: "packager/config.js"
+]
+
    
+
    Finally, you can update "start" under "scripts" on your package.json to use the config:
    
+
    "start": "node node_modules/react-native/local-cli/cli.js start --config ../../../../packager/config.js",
    
+
    Start your package server with npm start. Note that when the dev packager is automatically launched via xcode and react-native run-android, etc, it does not use npm start, so it won't use the config.
    
+
    Investigating the Loaded Modules
    
+
    In your root file (index.(ios|android).js) you can add the following after the initial imports:
    
+
    const modules = require.getModules();
+const moduleIds = Object.keys(modules);
+const loadedModuleNames = moduleIds
+  .filter(moduleId => modules[moduleId].isInitialized)
+  .map(moduleId => modules[moduleId].verboseName);
+const waitingModuleNames = moduleIds
+  .filter(moduleId => !modules[moduleId].isInitialized)
+  .map(moduleId => modules[moduleId].verboseName);
+
+// make sure that the modules you expect to be waiting are actually waiting
+console.log(
+  'loaded:',
+  loadedModuleNames.length,
+  'waiting:',
+  waitingModuleNames.length
+);
+
+// grab this text blob, and put it in a file named packager/modulePaths.js
+console.log(`module.exports = ${JSON.stringify(loadedModuleNames.sort())};`);
+
    
+
    When you run your app, you can look in the console and see how many modules have been loaded, and how many are waiting. You may want to read the moduleNames and see if there are any surprises. Note that inline requires are invoked the first time the imports are referenced. You may need to investigate and refactor to ensure only the modules you want are loaded on startup. Note that you can change the Systrace object on require to help debug problematic requires.
    
+
    require.Systrace.beginEvent = (message) => {
+  if(message.includes(problematicModule)) {
+    throw new Error();
+  }
+}
+
    
+
    Every app is different, but it may make sense to only load the modules you need for the very first screen. When you are satisified, put the output of the loadedModuleNames into a file named packager/modulePaths.js.
    
+
    Updating the config.js
    
+
    Returning to packager/config.js we should update it to use our newly generated modulePaths.js file.
    
+
    const modulePaths = require('./modulePaths');
+const resolve = require('path').resolve;
+const fs = require('fs');
+
+// Update the following line if the root folder of your app is somewhere else.
+const ROOT_FOLDER = resolve(__dirname, '..');
+
+const config = {
+  transformer: {
+    getTransformOptions: () => {
+      const moduleMap = {};
+      modulePaths.forEach(path => {
+        if (fs.existsSync(path)) {
+          moduleMap[resolve(path)] = true;
+        }
+      });
+      return {
+        preloadedModules: moduleMap,
+        transform: { inlineRequires: { blacklist: moduleMap } },
+      };
+    },
+  },
+  projectRoot:ROOT_FOLDER,
+};
+
+module.exports = config;
+
    
+
    The preloadedModules entry in the config indicates which modules should be marked as preloaded when building a RAM bundle. When the bundle is loaded, those modules are immediately loaded, before any requires have even executed. The blacklist entry indicates that those modules should not be required inline. Because they are preloaded, there is no performance benefit from using an inline require. In fact the javascript spends extra time resolving the inline require every time the imports are referenced.
    
+
    Test and Measure Improvements
    
+
    You should now be ready to build your app using the RAM format and inline requires. Make sure you measure the before and after startup times.

    Performance
    A compelling reason for using React Native instead of WebView-based tools is to achieve 60 frames per second and a native look and feel to your apps. Where possible, we would like for React Native to do the right thing and help you to focus on your app instead of performance optimization, but there are areas where we're not quite there yet, and others where React Native (similar to writing native code directly) cannot possibly determine the best way to optimize for you and so manual intervention will be necessary. We try our best to deliver buttery-smooth UI performance by default, but sometimes that just isn't possible.
    
+
    This guide is intended to teach you some basics to help you to troubleshoot performance issues, as well as discuss common sources of problems and their suggested solutions.
    
+
    What you need to know about frames
    
+
    Your grandparents' generation called movies "moving pictures" for a reason: realistic motion in video is an illusion created by quickly changing static images at a consistent speed. We refer to each of these images as frames. The number of frames that is displayed each second has a direct impact on how smooth and ultimately life-like a video (or user interface) seems to be. iOS devices display 60 frames per second, which gives you and the UI system about 16.67ms to do all of the work needed to generate the static image (frame) that the user will see on the screen for that interval. If you are unable to do the work necessary to generate that frame within the allotted 16.67ms, then you will "drop a frame" and the UI will appear unresponsive.
    
+
    Now to confuse the matter a little bit, open up the developer menu in your app and toggle Show Perf Monitor. You will notice that there are two different frame rates.
    
+
    
+
    JS frame rate (JavaScript thread)
    
+
    For most React Native applications, your business logic will run on the JavaScript thread. This is where your React application lives, API calls are made, touch events are processed, etc... Updates to native-backed views are batched and sent over to the native side at the end of each iteration of the event loop, before the frame deadline (if all goes well). If the JavaScript thread is unresponsive for a frame, it will be considered a dropped frame. For example, if you were to call this.setState on the root component of a complex application and it resulted in re-rendering computationally expensive component subtrees, it's conceivable that this might take 200ms and result in 12 frames being dropped. Any animations controlled by JavaScript would appear to freeze during that time. If anything takes longer than 100ms, the user will feel it.
    
+
    This often happens during Navigator transitions: when you push a new route, the JavaScript thread needs to render all of the components necessary for the scene in order to send over the proper commands to the native side to create the backing views. It's common for the work being done here to take a few frames and cause jank because the transition is controlled by the JavaScript thread. Sometimes components will do additional work on componentDidMount, which might result in a second stutter in the transition.
    
+
    Another example is responding to touches: if you are doing work across multiple frames on the JavaScript thread, you might notice a delay in responding to TouchableOpacity, for example. This is because the JavaScript thread is busy and cannot process the raw touch events sent over from the main thread. As a result, TouchableOpacity cannot react to the touch events and command the native view to adjust its opacity.
    
+
    UI frame rate (main thread)
    
+
    Many people have noticed that performance of NavigatorIOS is better out of the box than Navigator. The reason for this is that the animations for the transitions are done entirely on the main thread, and so they are not interrupted by frame drops on the JavaScript thread.
    
+
    Similarly, you can happily scroll up and down through a ScrollView when the JavaScript thread is locked up because the ScrollView lives on the main thread. The scroll events are dispatched to the JS thread, but their receipt is not necessary for the scroll to occur.
    
+
    Common sources of performance problems
    
+
    Running in development mode (dev=true)
    
+
    JavaScript thread performance suffers greatly when running in dev mode. This is unavoidable: a lot more work needs to be done at runtime to provide you with good warnings and error messages, such as validating propTypes and various other assertions. Always make sure to test performance in release builds.
    
+
    Using console.log statements
    
+
    When running a bundled app, these statements can cause a big bottleneck in the JavaScript thread. This includes calls from debugging libraries such as redux-logger, so make sure to remove them before bundling. You can also use this babel plugin that removes all the console.* calls. You need to install it first with npm i babel-plugin-transform-remove-console --save-dev, and then edit the .babelrc file under your project directory like this:
    
+
    {
+  "env": {
+    "production": {
+      "plugins": ["transform-remove-console"]
+    }
+  }
+}
+
    
+
    This will automatically remove all console.* calls in the release (production) versions of your project.
    
+
    ListView initial rendering is too slow or scroll performance is bad for large lists
    
+
    Use the new FlatList or SectionList component instead. Besides simplifying the API, the new list components also have significant performance enhancements, the main one being nearly constant memory usage for any number of rows.
    
+
    If your FlatList is rendering slow, be sure that you've implemented getItemLayout to optimize rendering speed by skipping measurement of the rendered items.
    
+
    JS FPS plunges when re-rendering a view that hardly changes
    
+
    If you are using a ListView, you must provide a rowHasChanged function that can reduce a lot of work by quickly determining whether or not a row needs to be re-rendered. If you are using immutable data structures, this would be as simple as a reference equality check.
    
+
    Similarly, you can implement shouldComponentUpdate and indicate the exact conditions under which you would like the component to re-render. If you write pure components (where the return value of the render function is entirely dependent on props and state), you can leverage PureComponent to do this for you. Once again, immutable data structures are useful to keep this fast -- if you have to do a deep comparison of a large list of objects, it may be that re-rendering your entire component would be quicker, and it would certainly require less code.
    
+
    Dropping JS thread FPS because of doing a lot of work on the JavaScript thread at the same time
    
+
    "Slow Navigator transitions" is the most common manifestation of this, but there are other times this can happen. Using InteractionManager can be a good approach, but if the user experience cost is too high to delay work during an animation, then you might want to consider LayoutAnimation.
    
+
    The Animated API currently calculates each keyframe on-demand on the JavaScript thread unless you set useNativeDriver: true, while LayoutAnimation leverages Core Animation and is unaffected by JS thread and main thread frame drops.
    
+
    One case where I have used this is for animating in a modal (sliding down from top and fading in a translucent overlay) while initializing and perhaps receiving responses for several network requests, rendering the contents of the modal, and updating the view where the modal was opened from. See the Animations guide for more information about how to use LayoutAnimation.
    
+
    Caveats:
    
+
      
+
    • LayoutAnimation only works for fire-and-forget animations ("static" animations) -- if it must be interruptible, you will need to use Animated.
      • 
+
    
+
    Moving a view on the screen (scrolling, translating, rotating) drops UI thread FPS
    
+
    This is especially true when you have text with a transparent background positioned on top of an image, or any other situation where alpha compositing would be required to re-draw the view on each frame. You will find that enabling shouldRasterizeIOS or renderToHardwareTextureAndroid can help with this significantly.
    
+
    Be careful not to overuse this or your memory usage could go through the roof. Profile your performance and memory usage when using these props. If you don't plan to move a view anymore, turn this property off.
    
+
    Animating the size of an image drops UI thread FPS
    
+
    On iOS, each time you adjust the width or height of an Image component it is re-cropped and scaled from the original image. This can be very expensive, especially for large images. Instead, use the transform: [{scale}] style property to animate the size. An example of when you might do this is when you tap an image and zoom it in to full screen.
    
+
    My TouchableX view isn't very responsive
    
+
    Sometimes, if we do an action in the same frame that we are adjusting the opacity or highlight of a component that is responding to a touch, we won't see that effect until after the onPress function has returned. If onPress does a setState that results in a lot of work and a few frames dropped, this may occur. A solution to this is to wrap any action inside of your onPress handler in requestAnimationFrame:
    
+
    handleOnPress() {
+  // Always use TimerMixin with requestAnimationFrame, setTimeout and
+  // setInterval
+  this.requestAnimationFrame(() => {
+    this.doExpensiveAction();
+  });
+}
+
    
+
    Slow navigator transitions
    
+
    As mentioned above, Navigator animations are controlled by the JavaScript thread. Imagine the "push from right" scene transition: each frame, the new scene is moved from the right to left, starting offscreen (let's say at an x-offset of 320) and ultimately settling when the scene sits at an x-offset of
    
+
      
+
    1. Each frame during this transition, the JavaScript thread needs to send a new x-offset to the main thread. If the JavaScript thread is locked up, it cannot do this and so no update occurs on that frame and the animation stutters.
      2. 
+
    
+
    One solution to this is to allow for JavaScript-based animations to be offloaded to the main thread. If we were to do the same thing as in the above example with this approach, we might calculate a list of all x-offsets for the new scene when we are starting the transition and send them to the main thread to execute in an optimized way. Now that the JavaScript thread is freed of this responsibility, it's not a big deal if it drops a few frames while rendering the scene -- you probably won't even notice because you will be too distracted by the pretty transition.
    
+
    Solving this is one of the main goals behind the new React Navigation library. The views in React Navigation use native components and the Animated library to deliver 60 FPS animations that are run on the native thread.
    
+
    Profiling
    
+
    Use the built-in profiler to get detailed information about work done in the JavaScript thread and main thread side-by-side. Access it by selecting Perf Monitor from the Debug menu.
    
+
    For iOS, Instruments is an invaluable tool, and on Android you should learn to use systrace.
    
+
    But first, make sure that Development Mode is OFF! You should see __DEV__ === false, development-level warning are OFF, performance optimizations are ON in your application logs.
    
+
    Another way to profile JavaScript is to use the Chrome profiler while debugging. This won't give you accurate results as the code is running in Chrome but will give you a general idea of where bottlenecks might be. Run the profiler under Chrome's Performance tab. A flame graph will appear under User Timing. To view more details in tabular format, click at the Bottom Up tab below and then select DedicatedWorker Thread at the top left menu.
    
+
    Profiling Android UI Performance with systrace
    
+
    Android supports 10k+ different phones and is generalized to support software rendering: the framework architecture and need to generalize across many hardware targets unfortunately means you get less for free relative to iOS. But sometimes, there are things you can improve -- and many times it's not native code's fault at all!
    
+
    The first step for debugging this jank is to answer the fundamental question of where your time is being spent during each 16ms frame. For that, we'll be using a standard Android profiling tool called systrace.
    
+
    systrace is a standard Android marker-based profiling tool (and is installed when you install the Android platform-tools package). Profiled code blocks are surrounded by start/end markers which are then visualized in a colorful chart format. Both the Android SDK and React Native framework provide standard markers that you can visualize.
    
+
    1. Collecting a trace
    
+
    First, connect a device that exhibits the stuttering you want to investigate to your computer via USB and get it to the point right before the navigation/animation you want to profile. Run systrace as follows:
    
+
    $ <path_to_android_sdk>/platform-tools/systrace/systrace.py --time=10 -o trace.html sched gfx view -a <your_package_name>
+
    
+
    A quick breakdown of this command:
    
+
      
+
    • time is the length of time the trace will be collected in seconds
      • 
+
    • sched, gfx, and view are the android SDK tags (collections of markers) we care about: sched gives you information about what's running on each core of your phone, gfx gives you graphics info such as frame boundaries, and view gives you information about measure, layout, and draw passes
      • 
+
    • -a <your_package_name> enables app-specific markers, specifically the ones built into the React Native framework. your_package_name can be found in the AndroidManifest.xml of your app and looks like com.example.app
      • 
+
    
+
    Once the trace starts collecting, perform the animation or interaction you care about. At the end of the trace, systrace will give you a link to the trace which you can open in your browser.
    
+
    2. Reading the trace
    
+
    After opening the trace in your browser (preferably Chrome), you should see something like this:
    
+
    Example
    
+
    
+
    HINT: Use the WASD keys to strafe and zoom
    
+
    
+
    If your trace .html file isn't opening correctly, check your browser console for the following:
    
+
    ObjectObserveError
    
+
    Since Object.observe was deprecated in recent browsers, you may have to open the file from the Google Chrome Tracing tool. You can do so by:
    
+
      
+
    • Opening tab in chrome chrome://tracing
      • 
+
    • Selecting load

    You should see zebra stripes as in the screenshot above. If you don't, try profiling on a different device: Samsung has been known to have issues displaying vsyncs while the Nexus series is generally pretty reliable.
    
+
    
+
    3. Find your process
    
+
    Scroll until you see (part of) the name of your package. In this case, I was profiling com.facebook.adsmanager, which shows up as book.adsmanager because of silly thread name limits in the kernel.
    
+
    On the left side, you'll see a set of threads which correspond to the timeline rows on the right. There are a few threads we care about for our purposes: the UI thread (which has your package name or the name UI Thread), mqt_js, and mqt_native_modules. If you're running on Android 5+, we also care about the Render Thread.
    
+
      
+
    • UI Thread. This is where standard android measure/layout/draw happens. The thread name on the right will be your package name (in my case book.adsmanager) or UI Thread. The events that you see on this thread should look something like this and have to do with Choreographer, traversals, and DispatchUI:
      
+
      UI Thread Example
      • 
+
    • JS Thread. This is where JavaScript is executed. The thread name will be either mqt_js or <...> depending on how cooperative the kernel on your device is being. To identify it if it doesn't have a name, look for things like JSCall, Bridge.executeJSCall, etc:
      
+
      JS Thread Example
      • 
+
    • Native Modules Thread. This is where native module calls (e.g. the UIManager) are executed. The thread name will be either mqt_native_modules or <...>. To identify it in the latter case, look for things like NativeCall, callJavaModuleMethod, and onBatchComplete:
      
+
      Native Modules Thread Example
      • 
+
    • Bonus: Render Thread. If you're using Android L (5.0) and up, you will also have a render thread in your application. This thread generates the actual OpenGL commands used to draw your UI. The thread name will be either RenderThread or <...>. To identify it in the latter case, look for things like DrawFrame and queueBuffer:
      
+
      Render Thread Example
      • 
+
    
+
    Identifying a culprit
    
+
    A smooth animation should look something like the following:
    
+
    Smooth Animation
    
+
    Each change in color is a frame -- remember that in order to display a frame, all our UI work needs to be done by the end of that 16ms period. Notice that no thread is working close to the frame boundary. An application rendering like this is rendering at 60 FPS.
    
+
    If you noticed chop, however, you might see something like this:
    
+
    Choppy Animation from JS
    
+
    Notice that the JS thread is executing basically all the time, and across frame boundaries! This app is not rendering at 60 FPS. In this case, the problem lies in JS.
    
+
    You might also see something like this:
    
+
    Choppy Animation from UI
    
+
    In this case, the UI and render threads are the ones that have work crossing frame boundaries. The UI that we're trying to render on each frame is requiring too much work to be done. In this case, the problem lies in the native views being rendered.
    
+
    At this point, you'll have some very helpful information to inform your next steps.
    
+
    Resolving JavaScript issues
    
+
    If you identified a JS problem, look for clues in the specific JS that you're executing. In the scenario above, we see RCTEventEmitter being called multiple times per frame. Here's a zoom-in of the JS thread from the trace above:
    
+
    Too much JS
    
+
    This doesn't seem right. Why is it being called so often? Are they actually different events? The answers to these questions will probably depend on your product code. And many times, you'll want to look into shouldComponentUpdate.
    
+
    Resolving native UI Issues
    
+
    If you identified a native UI problem, there are usually two scenarios:
    
+
      
+
    1. the UI you're trying to draw each frame involves too much work on the GPU, or
      2. 
+
    2. You're constructing new UI during the animation/interaction (e.g. loading in new content during a scroll).
      3. 
+
    
+
    Too much GPU work
    
+
    In the first scenario, you'll see a trace that has the UI thread and/or Render Thread looking like this:
    
+
    Overloaded GPU
    
+
    Notice the long amount of time spent in DrawFrame that crosses frame boundaries. This is time spent waiting for the GPU to drain its command buffer from the previous frame.
    
+
    To mitigate this, you should:
    
+
      
+
    • investigate using renderToHardwareTextureAndroid for complex, static content that is being animated/transformed (e.g. the Navigator slide/alpha animations)
      • 
+
    • make sure that you are not using needsOffscreenAlphaCompositing, which is disabled by default, as it greatly increases the per-frame load on the GPU in most cases.
      • 
+
    
+
    If these don't help and you want to dig deeper into what the GPU is actually doing, you can check out Tracer for OpenGL ES.
    
+
    Creating new views on the UI thread
    
+
    In the second scenario, you'll see something more like this:
    
+
    Creating Views
    
+
    Notice that first the JS thread thinks for a bit, then you see some work done on the native modules thread, followed by an expensive traversal on the UI thread.
    
+
    There isn't an easy way to mitigate this unless you're able to postpone creating new UI until after the interaction, or you are able to simplify the UI you're creating. The react native team is working on an infrastructure level solution for this that will allow new UI to be created and configured off the main thread, allowing the interaction to continue smoothly.
    
+
    RAM bundles + inline requires
    
+
    If you have a large app you may want to consider the Random Access Modules (RAM) bundle format, and using inline requires. This is useful for apps that have a large number of screens which may not ever be opened during a typical usage of the app. Generally it is useful to apps that have large amounts of code that are not needed for a while after startup. For instance the app includes complicated profile screens or lesser used features, but most sessions only involve visiting the main screen of the app for updates. We can optimize the loading of the bundle by using the RAM format and requiring those features and screens inline (when they are actually used).
    
+
    Loading JavaScript
    
+
    Before react-native can execute JS code, that code must be loaded into memory and parsed. With a standard bundle if you load a 50mb bundle, all 50mb must be loaded and parsed before any of it can be executed. The optimization behind RAM bundles is that you can load only the portion of the 50mb that you actually need at startup, and progressively load more of the bundle as those sections are needed.
    
+
    Inline Requires
    
+
    Inline requires delay the requiring of a module or file until that file is actually needed. A basic example would look like this:
    
+
    VeryExpensive.js
    
+
    import React, { Component } from 'react';
+import { Text } from 'react-native';
+// ... import some very expensive modules
+
+// You may want to log at the file level to verify when this is happening
+console.log('VeryExpensive component loaded');
+
+export default class VeryExpensive extends Component {
+  // lots and lots of code
+  render() {
+    return <Text>Very Expensive Component</Text>;
+  }
+}
+
    
+
    Optimized.js
    
+
    import React, { Component } from 'react';
+import { TouchableOpacity, View, Text } from 'react-native';
+
+let VeryExpensive = null;
+
+export default class Optimized extends Component {
+  state = { needsExpensive: false };
+
+  didPress = () => {
+    if (VeryExpensive == null) {
+      VeryExpensive = require('./VeryExpensive').default;
+    }
+
+    this.setState(() => ({
+      needsExpensive: true,
+    }));
+  };
+
+  render() {
+    return (
+      <View style={{ marginTop: 20 }}>
+        <TouchableOpacity onPress={this.didPress}>
+          <Text>Load</Text>
+        </TouchableOpacity>
+        {this.state.needsExpensive ? <VeryExpensive /> : null}
+      </View>
+    );
+  }
+}
+
    
+
    Even without the RAM format, inline requires can lead to startup time improvements, because the code within VeryExpensive.js will only execute once it is required for the first time.
    
+
    Enable the RAM format
    
+
    On iOS using the RAM format will create a single indexed file that react native will load one module at a time. On Android, by default it will create a set of files for each module. You can force Android to create a single file, like iOS, but using multiple files can be more performant and requires less memory.
    
+
    Enable the RAM format in Xcode by editing the build phase "Bundle React Native code and images". Before ../node_modules/react-native/scripts/react-native-xcode.sh add export BUNDLE_COMMAND="ram-bundle":
    
+
    export BUNDLE_COMMAND="ram-bundle"
+export NODE_BINARY=node
+../node_modules/react-native/scripts/react-native-xcode.sh
+
    
+
    On Android enable the RAM format by editing your android/app/build.gradle file. Before the line apply from: "../../node_modules/react-native/react.gradle" add or amend the project.ext.react block:
    
+
    project.ext.react = [
+  bundleCommand: "ram-bundle",
+]
+
    
+
    Use the following lines on Android if you want to use a single indexed file:
    
+
    project.ext.react = [
+  bundleCommand: "ram-bundle",
+  extraPackagerArgs: ["--indexed-ram-bundle"]
+]
+
    
+
    Configure Preloading and Inline Requires
    
+
    Now that we have a RAM bundle, there is overhead for calling require. require now needs to send a message over the bridge when it encounters a module it has not loaded yet. This will impact startup the most, because that is where the largest number of require calls are likely to take place while the app loads the initial module. Luckily we can configure a portion of the modules to be preloaded. In order to do this, you will need to implement some form of inline require.
    
+
    Adding a packager config file
    
+
    Create a folder in your project called packager, and create a single file named config.js. Add the following:
    
+
    const config = {
+  transformer: {
+    getTransformOptions: () => {
+      return {
+        transform: { inlineRequires: true },
+      };
+    },
+  },
+};
+
+module.exports = config;
+
    
+
    In Xcode, in the build phase, include export BUNDLE_CONFIG="packager/config.js".
    
+
    export BUNDLE_COMMAND="ram-bundle"
+export BUNDLE_CONFIG="packager/config.js"
+export NODE_BINARY=node
+../node_modules/react-native/scripts/react-native-xcode.sh
+
    
+
    Edit your android/app/build.gradle file to include bundleConfig: "packager/config.js",.
    
+
    project.ext.react = [
+  bundleCommand: "ram-bundle",
+  bundleConfig: "packager/config.js"
+]
+
    
+
    Finally, you can update "start" under "scripts" on your package.json to use the config:
    
+
    "start": "node node_modules/react-native/local-cli/cli.js start --config ../../../../packager/config.js",
    
+
    Start your package server with npm start. Note that when the dev packager is automatically launched via xcode and react-native run-android, etc, it does not use npm start, so it won't use the config.
    
+
    Investigating the Loaded Modules
    
+
    In your root file (index.(ios|android).js) you can add the following after the initial imports:
    
+
    const modules = require.getModules();
+const moduleIds = Object.keys(modules);
+const loadedModuleNames = moduleIds
+  .filter(moduleId => modules[moduleId].isInitialized)
+  .map(moduleId => modules[moduleId].verboseName);
+const waitingModuleNames = moduleIds
+  .filter(moduleId => !modules[moduleId].isInitialized)
+  .map(moduleId => modules[moduleId].verboseName);
+
+// make sure that the modules you expect to be waiting are actually waiting
+console.log(
+  'loaded:',
+  loadedModuleNames.length,
+  'waiting:',
+  waitingModuleNames.length
+);
+
+// grab this text blob, and put it in a file named packager/modulePaths.js
+console.log(`module.exports = ${JSON.stringify(loadedModuleNames.sort())};`);
+
    
+
    When you run your app, you can look in the console and see how many modules have been loaded, and how many are waiting. You may want to read the moduleNames and see if there are any surprises. Note that inline requires are invoked the first time the imports are referenced. You may need to investigate and refactor to ensure only the modules you want are loaded on startup. Note that you can change the Systrace object on require to help debug problematic requires.
    
+
    require.Systrace.beginEvent = (message) => {
+  if(message.includes(problematicModule)) {
+    throw new Error();
+  }
+}
+
    
+
    Every app is different, but it may make sense to only load the modules you need for the very first screen. When you are satisified, put the output of the loadedModuleNames into a file named packager/modulePaths.js.
    
+
    Updating the config.js
    
+
    Returning to packager/config.js we should update it to use our newly generated modulePaths.js file.
    
+
    const modulePaths = require('./modulePaths');
+const resolve = require('path').resolve;
+const fs = require('fs');
+
+// Update the following line if the root folder of your app is somewhere else.
+const ROOT_FOLDER = resolve(__dirname, '..');
+
+const config = {
+  transformer: {
+    getTransformOptions: () => {
+      const moduleMap = {};
+      modulePaths.forEach(path => {
+        if (fs.existsSync(path)) {
+          moduleMap[resolve(path)] = true;
+        }
+      });
+      return {
+        preloadedModules: moduleMap,
+        transform: { inlineRequires: { blacklist: moduleMap } },
+      };
+    },
+  },
+  projectRoot:ROOT_FOLDER,
+};
+
+module.exports = config;
+
    
+
    The preloadedModules entry in the config indicates which modules should be marked as preloaded when building a RAM bundle. When the bundle is loaded, those modules are immediately loaded, before any requires have even executed. The blacklist entry indicates that those modules should not be required inline. Because they are preloaded, there is no performance benefit from using an inline require. In fact the javascript spends extra time resolving the inline require every time the imports are referenced.
    
+
    Test and Measure Improvements
    
+
    You should now be ready to build your app using the RAM format and inline requires. Make sure you measure the before and after startup times.

    PermissionsAndroid
    
+
    PermissionsAndroid provides access to Android M's new permissions model. The so-called "normal" permissions are granted by default when the application is installed as long as they appear in AndroidManifest.xml. However, "dangerous" permissions require a dialog prompt. You should use this module for those permissions.
    
+
    On devices before SDK version 23, the permissions are automatically granted if they appear in the manifest, so check should always result to true and request should always resolve to PermissionsAndroid.RESULTS.GRANTED.
    
+
    If a user has previously turned off a permission that you prompt for, the OS will advise your app to show a rationale for needing the permission. The optional rationale argument will show a dialog prompt only if necessary - otherwise the normal permission prompt will appear.
    
+
    Example
    
+
    import {PermissionsAndroid} from 'react-native';
+
+async function requestCameraPermission() {
+  try {

+      PermissionsAndroid.PERMISSIONS.CAMERA,
+      {

+        message:
+          'Cool Photo App needs access to your camera ' +
+          'so you can take awesome pictures.',

+        buttonNegative: 'Cancel',
+        buttonPositive: 'OK',

    PixelRatio
    PixelRatio class gives access to the device pixel density.
    
+
    Fetching a correctly sized image
    
+
    You should get a higher resolution image if you are on a high pixel density device. A good rule of thumb is to multiply the size of the image you display by the pixel ratio.
    
+
    var image = getImage({
+  width: PixelRatio.getPixelSizeForLayoutSize(200),
+  height: PixelRatio.getPixelSizeForLayoutSize(100),
+});
+<Image source={image} style={{width: 200, height: 100}} />;
+
    
+
    Pixel grid snapping
    
+
    In iOS, you can specify positions and dimensions for elements with arbitrary precision, for example 29.674825. But, ultimately the physical display only have a fixed number of pixels, for example 640×960 for iPhone 4 or 750×1334 for iPhone 6. iOS tries to be as faithful as possible to the user value by spreading one original pixel into multiple ones to trick the eye. The downside of this technique is that it makes the resulting element look blurry.
    
+
    In practice, we found out that developers do not want this feature and they have to work around it by doing manual rounding in order to avoid having blurry elements. In React Native, we are rounding all the pixels automatically.
    
+
    We have to be careful when to do this rounding. You never want to work with rounded and unrounded values at the same time as you're going to accumulate rounding errors. Having even one rounding error is deadly because a one pixel border may vanish or be twice as big.
    
+
    In React Native, everything in JavaScript and within the layout engine works with arbitrary precision numbers. It's only when we set the position and dimensions of the native element on the main thread that we round. Also, rounding is done relative to the root rather than the parent, again to avoid accumulating rounding errors.

    Methods

    static get()

    Returns the device pixel density. Some examples:
    
+
+
    
+
    getFontScale()
    
+
    static getFontScale()
+
    
+
    Returns the scaling factor for font sizes. This is the ratio that is used to calculate the absolute font size, so any elements that heavily depend on that should use this to do calculations.
    
+
    If a font scale is not set, this returns the device pixel ratio.
    
+
    Currently this is only implemented on Android and reflects the user preference set in Settings > Display > Font size, on iOS it will always return the default pixel ratio. @platform android

+
    getPixelSizeForLayoutSize()
    
+
    static getPixelSizeForLayoutSize(layoutSize)
+

    Converts a layout size (dp) to pixel size (px).
    
+
    Guaranteed to return an integer number.
    
+
    
+
    roundToNearestPixel()
    
+
    static roundToNearestPixel(layoutSize)
+
    
+
    Rounds a layout size (dp) to the nearest layout size that corresponds to an integer number of pixels. For example, on a device with a PixelRatio of 3, PixelRatio.roundToNearestPixel(8.4) = 8.33, which corresponds to exactly (8.33 * 3) = 25 pixels.

    If a font scale is not set, this returns the device pixel ratio.
    
+
    Currently this is only implemented on Android and reflects the user preference set in Settings > Display > Font size, on iOS it will always return the default pixel ratio. @platform android

    Guaranteed to return an integer number.
    
+
    
+
    roundToNearestPixel()
    
+
    static roundToNearestPixel(layoutSize)
+
    
+
    Rounds a layout size (dp) to the nearest layout size that corresponds to an integer number of pixels. For example, on a device with a PixelRatio of 3, PixelRatio.roundToNearestPixel(8.4) = 8.33, which corresponds to exactly (8.33 * 3) = 25 pixels.

    Platform Specific Code
    When building a cross-platform app, you'll want to re-use as much code as possible. Scenarios may arise where it makes sense for the code to be different, for example you may want to implement separate visual components for iOS and Android.
    
+
    React Native provides two ways to easily organize your code and separate it by platform:
    
+
+
    Certain components may have properties that work on one platform only. All of these props are annotated with @platform and have a small badge next to them on the website.
    
+
    Platform module
    
+
    React Native provides a module that detects the platform in which the app is running. You can use the detection logic to implement platform-specific code. Use this option when only small parts of a component are platform-specific.
    
+
    import {Platform, StyleSheet} from 'react-native';
+
+const styles = StyleSheet.create({
+  height: Platform.OS === 'ios' ? 200 : 100,
+});
+
    
+
    Platform.OS will be ios when running on iOS and android when running on Android.
    
+
    There is also a Platform.select method available, that given an object containing Platform.OS as keys, returns the value for the platform you are currently running on.
    
+
    import {Platform, StyleSheet} from 'react-native';
+
+const styles = StyleSheet.create({
+  container: {
+    flex: 1,
+    ...Platform.select({
+      ios: {
+        backgroundColor: 'red',
+      },
+      android: {
+        backgroundColor: 'blue',
+      },
+    }),
+  },
+});
+
    
+
    This will result in a container having flex: 1 on both platforms, a red background color on iOS, and a blue background color on Android.
    
+
    Since it accepts any value, you can also use it to return platform specific component, like below:
    
+
    const Component = Platform.select({
+  ios: () => require('ComponentIOS'),
+  android: () => require('ComponentAndroid'),
+})();
+
+<Component />;
+
    
+
    Detecting the Android version
    
+
    On Android, the Platform module can also be used to detect the version of the Android Platform in which the app is running:
    
+
    import {Platform} from 'react-native';
+
+if (Platform.Version === 25) {
+  console.log('Running on Nougat!');
+}
+
    
+
    Detecting the iOS version
    
+
    On iOS, the Version is a result of -[UIDevice systemVersion], which is a string with the current version of the operating system. An example of the system version is "10.3". For example, to detect the major version number on iOS:
    
+
    import {Platform} from 'react-native';
+
+const majorVersionIOS = parseInt(Platform.Version, 10);
+if (majorVersionIOS <= 9) {
+  console.log('Work around a change in behavior');
+}
+
    
+
    Platform-specific extensions
    
+
    When your platform-specific code is more complex, you should consider splitting the code out into separate files. React Native will detect when a file has a .ios. or .android. extension and load the relevant platform file when required from other components.
    
+
    For example, say you have the following files in your project:
    
+
    BigButton.ios.js
+BigButton.android.js
+
    
+
    You can then require the component as follows:
    
+
    import BigButton from './BigButton';
+
    
+
    React Native will automatically pick up the right file based on the running platform.
    
+
    Native-specific extensions (i.e. sharing code with NodeJS and Web)
    
+
    You can also use the .native.js extension when a module needs to be shared between NodeJS/Web and React Native but it has no Android/iOS differences. This is specially useful for projects that has common code shared among React Native and ReactJS.
    
+
    For example, say you have the following files in your project:
    
+
    Container.js # picked up by Webpack, Rollup or any other Web bundler
+Container.native.js # picked up by the React Native bundler for both Android and iOS (Metro)
+
    
+
    You can still require it without the .native extension, as follows:
    
+
    import Container from './Container';
+
    
+
    Pro tip: Configure your Web bundler to ignore .native.js extensions in order to avoid having unused code in your production bundle, thus reducing the final bundle size.

    Props
    Most components can be customized when they are created, with different parameters. These creation parameters are called props.
    
+
    For example, one basic React Native component is the Image. When you create an image, you can use a prop named source to control what image it shows.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Image } from 'react-native';
+
+export default class Bananas extends Component {
+  render() {
+    let pic = {
+      uri: 'https://upload.wikimedia.org/wikipedia/commons/d/de/Bananavarieties.jpg'
+    };
+    return (
+      <Image source={pic} style={{width: 193, height: 110}}/>
+    );
+  }

+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => Bananas);
+
    
+
+
    Notice the braces surrounding {pic} - these embed the variable pic into JSX. You can put any JavaScript expression inside braces in JSX.
    
+
    Your own components can also use props. This lets you make a single component that is used in many different places in your app, with slightly different properties in each place. Just refer to this.props in your render function. Here's an example:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Text, View } from 'react-native';
+
+class Greeting extends Component {
+  render() {
+    return (
+      <View style={{alignItems: 'center'}}>
+        <Text>Hello {this.props.name}!</Text>
+      </View>
+    );
+  }
+}
+
+export default class LotsOfGreetings extends Component {
+  render() {
+    return (
+      <View style={{alignItems: 'center'}}>
+        <Greeting name='Rexxar' />
+        <Greeting name='Jaina' />
+        <Greeting name='Valeera' />
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => LotsOfGreetings);
+
    
+
+
    Using name as a prop lets us customize the Greeting component, so we can reuse that component for each of our greetings. This example also uses the Greeting component in JSX, just like the built-in components. The power to do this is what makes React so cool - if you find yourself wishing that you had a different set of UI primitives to work with, you just invent new ones.
    
+
    The other new thing going on here is the View component. A View is useful as a container for other components, to help control style and layout.
    
+
    With props and the basic Text, Image, and View components, you can build a wide variety of static screens. To learn how to make your app change over time, you need to learn about State.

    Props
    Most components can be customized when they are created, with different parameters. These creation parameters are called props.
    
+
    For example, one basic React Native component is the Image. When you create an image, you can use a prop named source to control what image it shows.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Image } from 'react-native';
+
+export default class Bananas extends Component {
+  render() {
+    let pic = {
+      uri: 'https://upload.wikimedia.org/wikipedia/commons/d/de/Bananavarieties.jpg'
+    };
+    return (
+      <Image source={pic} style={{width: 193, height: 110}}/>
+    );
+  }
+}
+
+// skip this line if using Create React Native App

+
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription

    handlerfunctionYesListener.
    
+
    Valid events are:
    
+
      
+
    • notification : Fired when a remote notification is received. The handler will be invoked with an instance of PushNotificationIOS.
      • 
+
    • localNotification : Fired when a local notification is received. The handler will be invoked with an instance of PushNotificationIOS.
      • 
+
    • register: Fired when the user registers for remote notifications. The handler will be invoked with a hex string representing the deviceToken.
      • 
+
    • registrationError: Fired when the user fails to register for remote notifications. Typically occurs when APNS is having issues, or the device is a simulator. The handler will be invoked with {message: string, code: number, details: any}.
      • 
+
    
+
    
+
    removeEventListener()
    
+
    PushNotificationIOS.removeEventListener(type, handler);
+
    
+
    Removes the event listener. Do this in componentWillUnmount to prevent memory leaks
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    typestringYesEvent type.
    handlerfunctionYesListener.
    
+
    
+
    requestPermissions()
    
+
    PushNotificationIOS.requestPermissions([permissions]);
+
    
+
    Requests notification permissions from iOS, prompting the user's dialog box. By default, it will request all notification permissions, but a subset of these can be requested by passing a map of requested permissions. The following permissions are supported:
    
+
      
+
    • alert
      • 
+
    • badge
      • 
+
    • sound
      • 
+
    
+
    If a map is provided to the method, only the permissions with truthy values will be requested.
    
+
    This method returns a promise that will resolve when the user accepts, rejects, or if the permissions were previously rejected. The promise resolves to the current state of the permission.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    permissionsarrayNoalert, badge, or sound
    
+
    
+
    abandonPermissions()
    
+
    PushNotificationIOS.abandonPermissions();
+
    
+
    Unregister for all remote notifications received via Apple Push Notification service.
    
+
    You should call this method in rare circumstances only, such as when a new version of the app removes support for all types of remote notifications. Users can temporarily prevent apps from receiving remote notifications through the Notifications section of the Settings app. Apps unregistered through this method can always re-register.
    
+
    
+
    checkPermissions()
    
+
    PushNotificationIOS.checkPermissions(callback);
+
    
+
    See what push permissions are currently enabled.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    callbackfunctionYesSee below.
    
+
    callback will be invoked with a permissions object:
    
+
      
+
    • alert :boolean
      • 
+
    • badge :boolean
      • 
+
    • sound :boolean
      • 
+
    
+
    
+
    getInitialNotification()
    
+
    PushNotificationIOS.getInitialNotification();
+
    
+
    This method returns a promise. If the app was launched by a push notification, this promise resolves to an object of type PushNotificationIOS. Otherwise, it resolves to null.
    
+
    
+
    constructor()
    
+
    constructor(nativeNotif);
+
    
+
    You will never need to instantiate PushNotificationIOS yourself. Listening to the notification event and invoking getInitialNotification is sufficient.
    
+
    
+
    finish()
    
+
    finish(fetchResult);
+
    
+
    This method is available for remote notifications that have been received via: application:didReceiveRemoteNotification:fetchCompletionHandler: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/#//apple_ref/occ/intfm/UIApplicationDelegate/application:didReceiveRemoteNotification:fetchCompletionHandler:
    
+
    Call this to execute when the remote notification handling is complete. When calling this block, pass in the fetch result value that best describes the results of your operation. You must call this handler and should do so as soon as possible. For a list of possible values, see PushNotificationIOS.FetchResult.
    
+
    If you do not call this method your background remote notifications could be throttled, to read more about it see the above documentation link.
    
+
    
+
    getMessage()
    
+
    getMessage();
+
    
+
    An alias for getAlert to get the notification's main message string
    
+
    
+
    getSound()
    
+
    getSound();
+
    
+
    Gets the sound string from the aps object
    
+
    
+
    getCategory()
    
+
    getCategory();
+
    
+
    Gets the category string from the aps object
    
+
    
+
    getAlert()
    
+
    getAlert();
+
    
+
    Gets the notification's main message from the aps object
    
+
    
+
    getContentAvailable()
    
+
    getContentAvailable();
+
    
+
    Gets the content-available number from the aps object
    
+
    
+
    getBadgeCount()
    
+
    getBadgeCount();
+
    
+
    Gets the badge count number from the aps object
    
+
    
+
    getData()
    
+
    getData();
+

      • 
+
    • localNotification : Fired when a local notification is received. The handler will be invoked with an instance of PushNotificationIOS.
      • 
+
    • register: Fired when the user registers for remote notifications. The handler will be invoked with a hex string representing the deviceToken.
      • 
+
    • registrationError: Fired when the user fails to register for remote notifications. Typically occurs when APNS is having issues, or the device is a simulator. The handler will be invoked with {message: string, code: number, details: any}.

+
    
+
    requestPermissions()
    
+
    PushNotificationIOS.requestPermissions([permissions]);
+
    
+
    Requests notification permissions from iOS, prompting the user's dialog box. By default, it will request all notification permissions, but a subset of these can be requested by passing a map of requested permissions. The following permissions are supported:
    
+
      
+
    • alert
      • 
+
    • badge
      • 
+
    • sound
      • 
+
    
+
    If a map is provided to the method, only the permissions with truthy values will be requested.
    
+
    This method returns a promise that will resolve when the user accepts, rejects, or if the permissions were previously rejected. The promise resolves to the current state of the permission.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    permissionsarrayNoalert, badge, or sound
    
+
    
+
    abandonPermissions()
    
+
    PushNotificationIOS.abandonPermissions();
+
    
+
    Unregister for all remote notifications received via Apple Push Notification service.
    
+
    You should call this method in rare circumstances only, such as when a new version of the app removes support for all types of remote notifications. Users can temporarily prevent apps from receiving remote notifications through the Notifications section of the Settings app. Apps unregistered through this method can always re-register.
    
+
    
+
    checkPermissions()
    
+
    PushNotificationIOS.checkPermissions(callback);
+
    
+
    See what push permissions are currently enabled.
    
+
    Parameters:
    
+
+
+
+
+
+
+
+
    NameTypeRequiredDescription
    callbackfunctionYesSee below.
    
+
    callback will be invoked with a permissions object:
    
+
      
+
    • alert :boolean
      • 
+
    • badge :boolean
      • 
+
    • sound :boolean
      • 
+
    
+
    
+
    getInitialNotification()
    
+
    PushNotificationIOS.getInitialNotification();
+
    
+
    This method returns a promise. If the app was launched by a push notification, this promise resolves to an object of type PushNotificationIOS. Otherwise, it resolves to null.
    
+
    
+
    constructor()
    
+
    constructor(nativeNotif);
+
    
+
    You will never need to instantiate PushNotificationIOS yourself. Listening to the notification event and invoking getInitialNotification is sufficient.
    
+
    
+
    finish()
    
+
    finish(fetchResult);
+
    
+
    This method is available for remote notifications that have been received via: application:didReceiveRemoteNotification:fetchCompletionHandler: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/#//apple_ref/occ/intfm/UIApplicationDelegate/application:didReceiveRemoteNotification:fetchCompletionHandler:
    
+
    Call this to execute when the remote notification handling is complete. When calling this block, pass in the fetch result value that best describes the results of your operation. You must call this handler and should do so as soon as possible. For a list of possible values, see PushNotificationIOS.FetchResult.
    
+
    If you do not call this method your background remote notifications could be throttled, to read more about it see the above documentation link.
    
+
    
+
    getMessage()
    
+
    getMessage();
+
    
+
    An alias for getAlert to get the notification's main message string

    RefreshControl
    This component is used inside a ScrollView or ListView to add pull to refresh functionality. When the ScrollView is at scrollY: 0, swiping down triggers an onRefresh event.
    
+
    Usage example
    
+
    import { ScrollView, RefreshControl } from 'react-native';
+
+class RefreshableList extends Component {
+  constructor(props) {
+    super(props);
+    this.state = {
+      refreshing: false,
+    };
+  }
+
+  _onRefresh = () => {
+    this.setState({refreshing: true});
+    fetchData().then(() => {
+      this.setState({refreshing: false});
+    });
+  }
+
+  render() {
+    return (
+      <ScrollView
+        refreshControl={
+          <RefreshControl
+            refreshing={this.state.refreshing}
+            onRefresh={this._onRefresh}
+          />
+        }
+        ...
+      />
+    );
+  }
+  ...
+}
+
    
+
    Note: refreshing is a controlled prop, this is why it needs to be set to true in the onRefresh function otherwise the refresh indicator will stop immediately.

+Removing Default Permissions · React Native
    0.58
    Edit
    Removing Default Permissions
    By default, some permissions are added to your Android APK.
    
+
    The default permissions that get added are:
    
+
      
+
    • android.permission.INTERNET - Required for debug mode.
      • 
+
    • android.permission.SYSTEM_ALERT_WINDOW - Required for debug mode.
      • 
+
    • android.permission.READ_PHONE_STATE - Not required for debug or production.
      • 
+
    • android.permission.WRITE_EXTERNAL_STORAGE - Not required for debug or production.
      • 
+
    • android.permission.READ_EXTERNAL_STORAGE - Not required for debug or production.
      • 
+
    
+
      
+
    1. Let's start by removing READ_PHONE_STATE, WRITE_EXTERNAL_STORAGE, and READ_EXTERNAL_STORAGE from both production and debug APKs, as it is not required in either. These storage permissions are still not needed if AsyncStorage module is in use, so it is safe to remove from both production and debug.
      2. 
+
    2. Open your android/app/src/main/AndroidManifest.xml file.
      3. 
+
    3. Even though these three permissions are not listed in the manifest they get added in. We add the three permissions with tools:node="remove" attribute, to make sure it gets removed during build. Note that the package identifier will be different, for below it is "com.myapp" because the project was created with react-native init myapp.
      
+
      <manifest xmlns:android="http://schemas.android.com/apk/res/android"
+    package="com.myappid"
++   xmlns:tools="http://schemas.android.com/tools"
+    >
+
+    <uses-permission android:name="android.permission.INTERNET" />
+    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
++   <uses-permission tools:node="remove" android:name="android.permission.READ_PHONE_STATE" />
++   <uses-permission tools:node="remove" android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
++   <uses-permission tools:node="remove" android:name="android.permission.READ_EXTERNAL_STORAGE" />
+
+    <application
+      android:name=".MainApplication"
+      android:label="@string/app_name"
+      android:icon="@mipmap/ic_launcher"

+      </activity>
+      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
+    </application>
+
+</manifest>
+
      4. 
+
    4. Now let's remove SYSTEM_ALERT_WINDOW from the production APK only.
      5. 
+
    5. Go to the android/app/src/ directory. Create a new directory inside this directory, called release. (path: android/app/src/release/)
      6. 
+
    6. Inside this android/app/src/release/ directory create a AndroidManifest.xml file. (path: android/app/src/release/AndroidManifest.xml)
      7. 
+
    7. Inside this file paste the following contents. Note, make sure to update your package identifier from "com.myapp" to what yours is.
      
+
      <manifest xmlns:android="http://schemas.android.com/apk/res/android"
+    package="com.myapp"
+    xmlns:tools="http://schemas.android.com/tools">
+
+    <uses-permission tools:node="remove" android:name="android.permission.SYSTEM_ALERT_WINDOW" />
+
+</manifest>
+
      8. 
+
    
+
    That's it. We did not remove the INTERNET permission as pretty much all apps use it. Now whenever you create a production APK all these 4 permissions will be removed. When you create a debug APK (react-native run-android) it will install the APK with only the three permissions removed, and SYSTEM_ALERT_WINDOW will remain.

    Edit
    Removing Default Permissions
    By default, some permissions are added to your Android APK.
    
+
    The default permissions that get added are:
    
+
      
+
    • android.permission.INTERNET - Required for debug mode.
      • 
+
    • android.permission.SYSTEM_ALERT_WINDOW - Required for debug mode.
      • 
+
    • android.permission.READ_PHONE_STATE - Not required for debug or production.
      • 
+
    • android.permission.WRITE_EXTERNAL_STORAGE - Not required for debug or production.
      • 
+
    • android.permission.READ_EXTERNAL_STORAGE - Not required for debug or production.
      • 
+
    
+
      
+
    1. Let's start by removing READ_PHONE_STATE, WRITE_EXTERNAL_STORAGE, and READ_EXTERNAL_STORAGE from both production and debug APKs, as it is not required in either. These storage permissions are still not needed if AsyncStorage module is in use, so it is safe to remove from both production and debug.
      2. 
+
    2. Open your android/app/src/main/AndroidManifest.xml file.
      3. 
+
    3. Even though these three permissions are not listed in the manifest they get added in. We add the three permissions with tools:node="remove" attribute, to make sure it gets removed during build. Note that the package identifier will be different, for below it is "com.myapp" because the project was created with react-native init myapp.
      
+
      <manifest xmlns:android="http://schemas.android.com/apk/res/android"
+    package="com.myappid"
++   xmlns:tools="http://schemas.android.com/tools"
+    >
+
+    <uses-permission android:name="android.permission.INTERNET" />
+    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
++   <uses-permission tools:node="remove" android:name="android.permission.READ_PHONE_STATE" />
++   <uses-permission tools:node="remove" android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
++   <uses-permission tools:node="remove" android:name="android.permission.READ_EXTERNAL_STORAGE" />
+
+    <application
+      android:name=".MainApplication"
+      android:label="@string/app_name"
+      android:icon="@mipmap/ic_launcher"
+      android:allowBackup="false"
+      android:theme="@style/AppTheme">
+      <activity
+        android:name=".MainActivity"
+        android:label="@string/app_name"
+        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
+        android:windowSoftInputMode="adjustResize">
+        <intent-filter>
+            <action android:name="android.intent.action.MAIN" />
+            <category android:name="android.intent.category.LAUNCHER" />
+        </intent-filter>
+      </activity>
+      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
+    </application>
+
+</manifest>
+
      4. 
+
    4. Now let's remove SYSTEM_ALERT_WINDOW from the production APK only.
      5. 
+
    5. Go to the android/app/src/ directory. Create a new directory inside this directory, called release. (path: android/app/src/release/)
      6. 
+
    6. Inside this android/app/src/release/ directory create a AndroidManifest.xml file. (path: android/app/src/release/AndroidManifest.xml)
      7. 
+
    7. Inside this file paste the following contents. Note, make sure to update your package identifier from "com.myapp" to what yours is.
      
+
      <manifest xmlns:android="http://schemas.android.com/apk/res/android"
+    package="com.myapp"
+    xmlns:tools="http://schemas.android.com/tools">
+
+    <uses-permission tools:node="remove" android:name="android.permission.SYSTEM_ALERT_WINDOW" />
+
+</manifest>
+
      8. 
+
    
+
    That's it. We did not remove the INTERNET permission as pretty much all apps use it. Now whenever you create a production APK all these 4 permissions will be removed. When you create a debug APK (react-native run-android) it will install the APK with only the three permissions removed, and SYSTEM_ALERT_WINDOW will remain.

    Running On Device
    
+
    It's always a good idea to test your app on an actual device before releasing it to your users. This document will guide you through the necessary steps to run your React Native app on a device and to get it ready for production.
    
+
    If you used Expo CLI or Create React Native App to set up your project, you can preview your app on a device by scanning the QR code with the Expo app. In order to build and run your app on a device, you will need to eject and install the native code dependencies from the Getting Started guide.
    
+
    
+  
      
+    
+    
+  
    
+
    
+
    
+
    Running your app on iOS devices
    
+
    
+
    Running your app on Android devices
    
+
    
+
    
+Development OS:
+macOS
+Linux
+Windows
+
    
+
    
+
    A Mac is required in order to build your app for iOS devices. Alternatively, you can refer to the Quick Start instructions to learn how to build your app using Expo CLI, which will allow you to run your app using the Expo client app.
    
+
    
+
    1. Plug in your device via USB
    
+
    Connect your iOS device to your Mac using a USB to Lightning cable. Navigate to the ios folder in your project, then open the .xcodeproj file, or if you are using CocoaPods open .xcworkspace, within it using Xcode.
    
+
    If this is your first time running an app on your iOS device, you may need to register your device for development. Open the Product menu from Xcode's menubar, then go to Destination. Look for and select your device from the list. Xcode will then register your device for development.
    
+
    2. Configure code signing
    
+
    Register for an Apple developer account if you don't have one yet.
    
+
    Select your project in the Xcode Project Navigator, then select your main target (it should share the same name as your project). Look for the "General" tab. Go to "Signing" and make sure your Apple developer account or team is selected under the Team dropdown. Do the same for the tests target (it ends with Tests, and is below your main target).
    
+
    
+
    Repeat this step for the Tests target in your project.
    
+
    3. Build and Run your app
    
+
    If everything is set up correctly, your device will be listed as the build target in the Xcode toolbar, and it will also appear in the Devices pane (⇧⌘2). You can now press the Build and run button (⌘R) or select Run from the Product menu. Your app will launch on your device shortly.
    
+
    
+
    
+
    If you run into any issues, please take a look at Apple's Launching Your App on a Device docs.
    
+
    
+
    
+
    1. Enable Debugging over USB
    
+
    Most Android devices can only install and run apps downloaded from Google Play, by default. You will need to enable USB Debugging on your device in order to install your app during development.
    
+
    To enable USB debugging on your device, you will first need to enable the "Developer options" menu by going to Settings → About phone and then tapping the Build number row at the bottom seven times. You can then go back to Settings → Developer options to enable "USB debugging".
    
+
    2. Plug in your device via USB
    
+
    Let's now set up an Android device to run our React Native projects. Go ahead and plug in your device via USB to your development machine.
    
+
    
+
    Next, check the manufacturer code by using lsusb (on mac, you must first install lsusb). lsusb should output something like this:
    
+
    $ lsusb
+Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 001 Device 003: ID 22b8:2e76 Motorola PCS
+Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
+Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+
    
+
    These lines represent the USB devices currently connected to your machine.
    
+
    You want the line that represents your phone. If you're in doubt, try unplugging your phone and running the command again:
    
+
    $ lsusb
+Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
+Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+
    
+
    You'll see that after removing the phone, the line which has the phone model ("Motorola PCS" in this case) disappeared from the list. This is the line that we care about.
    
+
    Bus 001 Device 003: ID 22b8:2e76 Motorola PCS
    
+
    From the above line, you want to grab the first four digits from the device ID:
    
+
    22b8:2e76
    
+
    In this case, it's 22b8. That's the identifier for Motorola.
    
+
    You'll need to input this into your udev rules in order to get up and running:
    
+
    echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", MODE="0666", GROUP="plugdev"' | sudo tee /etc/udev/rules.d/51-android-usb.rules
+
    
+
    Make sure that you replace 22b8 with the identifier you get in the above command.
    
+
    
+
    Now check that your device is properly connecting to ADB, the Android Debug Bridge, by running adb devices.
    
+
    $ adb devices
+List of devices attached
+emulator-5554 offline   # Google emulator
+14ed2fcc device         # Physical device
+
    
+
    Seeing device in the right column means the device is connected. You must have only one device connected at a time.
    
+
    3. Run your app
    
+
    Type the following in your command prompt to install and launch your app on the device:
    
+
    $ react-native run-android
+
    
+
    
+
    If you get a "bridge configuration isn't available" error, see Using adb reverse.
    
+
    
+
    
+
    Hint
    
+
    You can also use the React Native CLI to generate and run a Release build (e.g. react-native run-android --variant=release).
    
+
    
+
    
+
    
+
    Connecting to the development server
    
+
    You can also iterate quickly on a device using the development server. You only have to be on the same Wi-Fi network as your computer. Shake your device to open the Developer menu, then enable Live Reload. Your app will reload whenever your JavaScript code has changed.
    
+
    
+
    Troubleshooting
    
+
    
+
    If you have any issues, ensure that your Mac and device are on the same network and can reach each other. Many open wireless networks with captive portals are configured to prevent devices from reaching other devices on the network. You may use your device's Personal Hotspot feature in this case.
    
+
    
+
    When trying to connect to the development server you might get a red screen with an error saying:
    
+
    
+
    Connection to http://localhost:8081/debugger-proxy?role=client timed out. Are you running node proxy? If you are running on the device, check if you have the right IP address in RCTWebSocketExecutor.m.
    
+
    
+
    To solve this issue check the following points.
    
+
    1. Wi-Fi network.
    
+
    Make sure your laptop and your phone are on the same Wi-Fi network.
    
+
    2. IP address
    
+
    Make sure that the build script detected the IP address of your machine correctly (e.g. 10.0.1.123).
    
+
    
+
    Open the Report navigator tab, select the last Build and search for xip.io. The IP address which gets embedded in the app should match your machines IP address plus the domain .xip.io (e.g. 10.0.1.123.xip.io)
    
+
    3. Network/router configuration
    
+
    React Native uses the wildcard DNS service xip.io to address your device, as Apple ATS prohibits URLs with IP addresses instead of domain names, and developers' networks are often not set up to resolve local hostnames. Some routers have security features to prevent DNS Servers from resolving to anything in the local IP range.
    
+
    Now check if you are able to resolve the xip.io address, by running nslookup.
    
+
    $ nslookup 10.0.1.123.xip.io
+
    
+
    If it doesn't resolve your local IP address either the xip.io service is down or more likely your router prevents it.
    
+
    To still use xip.io behind your router:
    
+
      
+
    • configure your phone to use Google DNS (8.8.8.8)
      • 
+
    • disable the appropriate security feature in your router
      • 
+
    
+
    
+
    Connecting to the development server
    
+
    You can also iterate quickly on a device by connecting to the development server running on your development machine. There are several ways of accomplishing this, depending on whether you have access to a USB cable or a Wi-Fi network.
    
+
    Method 1: Using adb reverse (recommended)
    
+
    
+
    You can use this method if your device is running Android 5.0 (Lollipop) or newer, it has USB debugging enabled, and it is connected via USB to your development machine.
    
+
    
+
    Run the following in a command prompt:
    
+
    $ adb -s <device name> reverse tcp:8081 tcp:8081
+
    
+
    To find the device name, run the following adb command:
    
+
    $ adb devices
+
    
+
    You can now enable Live reloading from the Developer menu. Your app will reload whenever your JavaScript code has changed.
    
+
    Method 2: Connect via Wi-Fi
    
+
    You can also connect to the development server over Wi-Fi. You'll first need to install the app on your device using a USB cable, but once that has been done you can debug wirelessly by following these instructions. You'll need your development machine's current IP address before proceeding.
    
+
    
+
    You can find the IP address in System Preferences → Network.
    
+
    
+
    Open the command prompt and type ipconfig to find your machine's IP address (more info).
    
+
    
+
    Open a terminal and type /sbin/ifconfig to find your machine's IP address.
    
+
    
+
      
+
    1. Make sure your laptop and your phone are on the same Wi-Fi network.
      2. 
+
    2. Open your React Native app on your device.
      3. 
+
    3. You'll see a red screen with an error. This is OK. The following steps will fix that.
      4. 
+
    4. Open the in-app Developer menu.
      5. 
+
    5. Go to Dev Settings → Debug server host & port for device.
      6. 
+
    6. Type in your machine's IP address and the port of the local dev server (e.g. 10.0.1.1:8081).
      7. 
+
    7. Go back to the Developer menu and select Reload JS.
      8. 
+
    
+
    You can now enable Live reloading from the Developer menu. Your app will reload whenever your JavaScript code has changed.
    
+
    
+
    Building your app for production
    
+
    You have built a great app using React Native, and you are now itching to release it in the App Store. The process is the same as any other native iOS app, with some additional considerations to take into account.
    
+
    1. Enable App Transport Security
    
+
    App Transport Security is a security feature introduced in iOS 9 that rejects all HTTP requests that are not sent over HTTPS. This can result in HTTP traffic being blocked, including the developer React Native server. ATS is disabled for localhost by default in React Native projects in order to make development easier.
    
+
    You should re-enable ATS prior to building your app for production by removing the localhost entry from the NSExceptionDomains dictionary in your Info.plist file in the ios/ folder. You can also re-enable ATS from within Xcode by opening your target properties under the Info pane and editing the App Transport Security Settings entry.
    
+
    
+
    If your application needs to access HTTP resources on production, see this post to learn how to configure ATS on your project.
    
+
    
+
    2. Configure release scheme
    
+
    Building an app for distribution in the App Store requires using the Release scheme in Xcode. Apps built for Release will automatically disable the in-app Developer menu, which will prevent your users from inadvertently accessing the menu in production. It will also bundle the JavaScript locally, so you can put the app on a device and test whilst not connected to the computer.
    
+
    To configure your app to be built using the Release scheme, go to Product → Scheme → Edit Scheme. Select the Run tab in the sidebar, then set the Build Configuration dropdown to Release.
    
+
    
+
    Pro Tips
    
+
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
+
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
+  UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
+  launchScreenView.frame = self.window.bounds;
+  rootView.loadingView = launchScreenView;
+
    
+
    The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
+
     if [ "${CONFIGURATION}" == "Debug" ]; then
+  export SKIP_BUNDLING=true
+ fi
+
    
+
    3. Build app for release
    
+
    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.
    
+
    
+
    You can also use the React Native CLI to perform this operation using the option --configuration with the value Release (e.g. react-native run-ios --configuration Release).
    
+
    
+
    
+
    Building your app for production
    
+
    You have built a great app using React Native, and you are now itching to release it in the Play Store. The process is the same as any other native Android app, with some additional considerations to take into account. Follow the guide for generating a signed APK to learn more.

Go to "Signing" and make sure your Apple developer account or team is selected under the Team dropdown. Do the same for the tests target (it ends with Tests, and is below your main target).
    
+
    
+
    Repeat this step for the Tests target in your project.
    
+
    3. Build and Run your app
    
+
    If everything is set up correctly, your device will be listed as the build target in the Xcode toolbar, and it will also appear in the Devices pane (⇧⌘2). You can now press the Build and run button (⌘R) or select Run from the Product menu. Your app will launch on your device shortly.
    
+
    
+
    
+
    If you run into any issues, please take a look at Apple's Launching Your App on a Device docs.
    
+
    
+
    
+
    1. Enable Debugging over USB
    
+
    Most Android devices can only install and run apps downloaded from Google Play, by default. You will need to enable USB Debugging on your device in order to install your app during development.
    
+
    To enable USB debugging on your device, you will first need to enable the "Developer options" menu by going to Settings → About phone and then tapping the Build number row at the bottom seven times. You can then go back to Settings → Developer options to enable "USB debugging".
    
+
    2. Plug in your device via USB
    
+
    Let's now set up an Android device to run our React Native projects. Go ahead and plug in your device via USB to your development machine.
    
+
    
+
    Next, check the manufacturer code by using lsusb (on mac, you must first install lsusb). lsusb should output something like this:
    
+
    $ lsusb
+Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 001 Device 003: ID 22b8:2e76 Motorola PCS
+Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
+Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+
    
+
    These lines represent the USB devices currently connected to your machine.
    
+
    You want the line that represents your phone. If you're in doubt, try unplugging your phone and running the command again:
    
+
    $ lsusb
+Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
+Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
+Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+
    
+
    You'll see that after removing the phone, the line which has the phone model ("Motorola PCS" in this case) disappeared from the list. This is the line that we care about.
    
+
    Bus 001 Device 003: ID 22b8:2e76 Motorola PCS
    
+
    From the above line, you want to grab the first four digits from the device ID:
    
+
    22b8:2e76
    
+
    In this case, it's 22b8. That's the identifier for Motorola.
    
+
    You'll need to input this into your udev rules in order to get up and running:
    
+
    echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", MODE="0666", GROUP="plugdev"' | sudo tee /etc/udev/rules.d/51-android-usb.rules
+
    
+
    Make sure that you replace 22b8 with the identifier you get in the above command.
    
+
    
+
    Now check that your device is properly connecting to ADB, the Android Debug Bridge, by running adb devices.
    
+
    $ adb devices
+List of devices attached
+emulator-5554 offline   # Google emulator
+14ed2fcc device         # Physical device
+
    
+
    Seeing device in the right column means the device is connected. You must have only one device connected at a time.
    
+
    3. Run your app
    
+
    Type the following in your command prompt to install and launch your app on the device:
    
+
    $ react-native run-android
+
    
+
    
+
    If you get a "bridge configuration isn't available" error, see Using adb reverse.
    
+
    
+
    
+
    Hint
    
+
    You can also use the React Native CLI to generate and run a Release build (e.g. react-native run-android --variant=release).
    
+
    
+
    
+
    
+
    Connecting to the development server
    
+
    You can also iterate quickly on a device using the development server. You only have to be on the same Wi-Fi network as your computer. Shake your device to open the Developer menu, then enable Live Reload. Your app will reload whenever your JavaScript code has changed.
    
+
    
+
    Troubleshooting
    
+
    
+
    If you have any issues, ensure that your Mac and device are on the same network and can reach each other. Many open wireless networks with captive portals are configured to prevent devices from reaching other devices on the network. You may use your device's Personal Hotspot feature in this case.
    
+
    
+
    When trying to connect to the development server you might get a red screen with an error saying:
    
+
    
+
    Connection to http://localhost:8081/debugger-proxy?role=client timed out. Are you running node proxy? If you are running on the device, check if you have the right IP address in RCTWebSocketExecutor.m.
    
+
    
+
    To solve this issue check the following points.
    
+
    1. Wi-Fi network.
    
+
    Make sure your laptop and your phone are on the same Wi-Fi network.
    
+
    2. IP address
    
+
    Make sure that the build script detected the IP address of your machine correctly (e.g. 10.0.1.123).
    
+
    
+
    Open the Report navigator tab, select the last Build and search for xip.io. The IP address which gets embedded in the app should match your machines IP address plus the domain .xip.io (e.g. 10.0.1.123.xip.io)
    
+
    3. Network/router configuration
    
+
    React Native uses the wildcard DNS service xip.io to address your device, as Apple ATS prohibits URLs with IP addresses instead of domain names, and developers' networks are often not set up to resolve local hostnames. Some routers have security features to prevent DNS Servers from resolving to anything in the local IP range.
    
+
    Now check if you are able to resolve the xip.io address, by running nslookup.
    
+
    $ nslookup 10.0.1.123.xip.io
+
    
+
    If it doesn't resolve your local IP address either the xip.io service is down or more likely your router prevents it.
    
+
    To still use xip.io behind your router:
    
+
      
+
    • configure your phone to use Google DNS (8.8.8.8)
      • 
+
    • disable the appropriate security feature in your router
      • 
+
    
+
    
+
    Connecting to the development server
    
+
    You can also iterate quickly on a device by connecting to the development server running on your development machine. There are several ways of accomplishing this, depending on whether you have access to a USB cable or a Wi-Fi network.
    
+
    Method 1: Using adb reverse (recommended)
    
+
    
+
    You can use this method if your device is running Android 5.0 (Lollipop) or newer, it has USB debugging enabled, and it is connected via USB to your development machine.
    
+
    
+
    Run the following in a command prompt:
    
+
    $ adb -s <device name> reverse tcp:8081 tcp:8081
+
    
+
    To find the device name, run the following adb command:
    
+
    $ adb devices
+
    
+
    You can now enable Live reloading from the Developer menu. Your app will reload whenever your JavaScript code has changed.
    
+
    Method 2: Connect via Wi-Fi
    
+
    You can also connect to the development server over Wi-Fi. You'll first need to install the app on your device using a USB cable, but once that has been done you can debug wirelessly by following these instructions. You'll need your development machine's current IP address before proceeding.
    
+
    
+
    You can find the IP address in System Preferences → Network.
    
+
    
+
    Open the command prompt and type ipconfig to find your machine's IP address (more info).
    
+
    
+
    Open a terminal and type /sbin/ifconfig to find your machine's IP address.
    
+
    
+
      
+
    1. Make sure your laptop and your phone are on the same Wi-Fi network.
      2. 
+
    2. Open your React Native app on your device.
      3. 
+
    3. You'll see a red screen with an error. This is OK. The following steps will fix that.
      4. 
+
    4. Open the in-app Developer menu.
      5. 
+
    5. Go to Dev Settings → Debug server host & port for device.
      6. 
+
    6. Type in your machine's IP address and the port of the local dev server (e.g. 10.0.1.1:8081).
      7. 
+
    7. Go back to the Developer menu and select Reload JS.
      8. 
+
    
+
    You can now enable Live reloading from the Developer menu. Your app will reload whenever your JavaScript code has changed.
    
+
    
+
    Building your app for production
    
+
    You have built a great app using React Native, and you are now itching to release it in the App Store. The process is the same as any other native iOS app, with some additional considerations to take into account.
    
+
    1. Enable App Transport Security
    
+
    App Transport Security is a security feature introduced in iOS 9 that rejects all HTTP requests that are not sent over HTTPS. This can result in HTTP traffic being blocked, including the developer React Native server. ATS is disabled for localhost by default in React Native projects in order to make development easier.
    
+
    You should re-enable ATS prior to building your app for production by removing the localhost entry from the NSExceptionDomains dictionary in your Info.plist file in the ios/ folder. You can also re-enable ATS from within Xcode by opening your target properties under the Info pane and editing the App Transport Security Settings entry.
    
+
    
+
    If your application needs to access HTTP resources on production, see this post to learn how to configure ATS on your project.
    
+
    
+
    2. Configure release scheme
    
+
    Building an app for distribution in the App Store requires using the Release scheme in Xcode. Apps built for Release will automatically disable the in-app Developer menu, which will prevent your users from inadvertently accessing the menu in production. It will also bundle the JavaScript locally, so you can put the app on a device and test whilst not connected to the computer.
    
+
    To configure your app to be built using the Release scheme, go to Product → Scheme → Edit Scheme. Select the Run tab in the sidebar, then set the Build Configuration dropdown to Release.
    
+
    
+
    Pro Tips
    
+
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
+
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
+  UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
+  launchScreenView.frame = self.window.bounds;
+  rootView.loadingView = launchScreenView;
+
    
+
    The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
+
     if [ "${CONFIGURATION}" == "Debug" ]; then
+  export SKIP_BUNDLING=true
+ fi
+
    
+
    3. Build app for release
    
+
    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.
    
+
    
+
    You can also use the React Native CLI to perform this operation using the option --configuration with the value Release (e.g. react-native run-ios --configuration Release).
    
+
    
+
    
+
    Building your app for production
    
+
    You have built a great app using React Native, and you are now itching to release it in the Play Store. The process is the same as any other native Android app, with some additional considerations to take into account. Follow the guide for generating a signed APK to learn more.

    Once you have your React Native project initialized, you can run react-native run-ios inside the newly created project directory. If everything is set up correctly, you should see your new app running in the iOS Simulator shortly.
    
+
    Specifying a device
    
+
    You can specify the device the simulator should run with the --simulator flag, followed by the device name as a string. The default is "iPhone X". If you wish to run your app on an iPhone 4s, just run react-native run-ios --simulator="iPhone 4s".

    SafeAreaView
    The purpose of SafeAreaView is to render content within the safe area boundaries of a device. It is currently only applicable to iOS devices with iOS version 11 or later.
    
+
    SafeAreaView renders nested content and automatically applies paddings to reflect the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor views. Moreover, and most importantly, Safe Area's paddings reflect the physical limitation of the screen, such as rounded corners or camera notches (i.e. the sensor housing area on iPhone X).
    
+
    Usage Example
    
+
    Simply wrap your top level view with a SafeAreaView with a flex: 1 style applied to it. You may also want to use a background color that matches your application's design.
    
+
    <SafeAreaView style={{flex: 1, backgroundColor: '#fff'}}>
+  <View style={{flex: 1}}>
+    <Text>Hello World!</Text>

+ScrollView · React Native
    0.58
    Edit
    ScrollView
    Component that wraps platform ScrollView while providing integration with touch locking "responder" system.
    
+
    Keep in mind that ScrollViews must have a bounded height in order to work, since they contain unbounded-height children into a bounded container (via a scroll interaction). In order to bound the height of a ScrollView, either set the height of the view directly (discouraged) or make sure all parent views have bounded height. Forgetting to transfer {flex: 1} down the view stack can lead to errors here, which the element inspector makes easy to debug.
    
+
    Doesn't yet support other contained responders from blocking this scroll view from becoming the responder.
    
+
    <ScrollView> vs <FlatList> - which one to use?
    
+
    ScrollView simply renders all its react child components at once. That makes it very easy to understand and use.
    
+
    On the other hand, this has a performance downside. Imagine you have a very long list of items you want to display, maybe several screens worth of content. Creating JS components and native views for everything all at once, much of which may not even be shown, will contribute to slow rendering and increased memory usage.
    
+
    This is where FlatList comes into play. FlatList renders items lazily, just when they are about to appear, and removes items that scroll way off screen to save memory and processing time.
    
+
    FlatList is also handy if you want to render separators between your items, multiple columns, infinite scroll loading, or any number of other features it supports out of the box.

    scrollEventThrottle

    This controls how often the scroll event will be fired while scrolling (as a time interval in ms). A lower number yields better accuracy for code that is tracking the scroll position, but can lead to scroll performance problems due to the volume of information being send over the bridge. You will not notice a difference between values set between 1-16 as the JS run loop is synced to the screen refresh rate. If you do not need precise scroll position tracking, set this value higher to limit the information being sent across the bridge. The default value is zero, which results in the scroll event being sent only once each time the view is scrolled.

    scrollTo()

    scrollTo(([y]: number), object, ([x]: number), ([animated]: boolean));
+
    
+
    Scrolls to a given x, y offset, either immediately or with a smooth animation.
    
+
    Example:
    
+
    scrollTo({x: 0, y: 0, animated: true})
    
+
    Note: The weird function signature is due to the fact that, for historical reasons, the function also accepts separate arguments as an alternative to the options object. This is deprecated due to ambiguity (y before x), and SHOULD NOT BE USED.
    
+
    
+
    scrollToEnd()
    
+
    scrollToEnd(([options]: object));
+
    
+
    If this is a vertical ScrollView scrolls to the bottom. If this is a horizontal ScrollView scrolls to the right.
    
+
    Use scrollToEnd({animated: true}) for smooth animated scrolling, scrollToEnd({animated: false}) for immediate scrolling. If no options are passed, animated defaults to true.
    
+
    
+
    scrollWithoutAnimationTo()

    ScrollView
    Component that wraps platform ScrollView while providing integration with touch locking "responder" system.
    
+
    Keep in mind that ScrollViews must have a bounded height in order to work, since they contain unbounded-height children into a bounded container (via a scroll interaction). In order to bound the height of a ScrollView, either set the height of the view directly (discouraged) or make sure all parent views have bounded height. Forgetting to transfer {flex: 1} down the view stack can lead to errors here, which the element inspector makes easy to debug.
    
+
    Doesn't yet support other contained responders from blocking this scroll view from becoming the responder.
    
+
    <ScrollView> vs <FlatList> - which one to use?
    
+
    ScrollView simply renders all its react child components at once. That makes it very easy to understand and use.
    
+
    On the other hand, this has a performance downside. Imagine you have a very long list of items you want to display, maybe several screens worth of content. Creating JS components and native views for everything all at once, much of which may not even be shown, will contribute to slow rendering and increased memory usage.
    
+
    This is where FlatList comes into play. FlatList renders items lazily, just when they are about to appear, and removes items that scroll way off screen to save memory and processing time.
    
+
    FlatList is also handy if you want to render separators between your items, multiple columns, infinite scroll loading, or any number of other features it supports out of the box.

    endFillColor
    
+
    Sometimes a scrollview takes up more space than its content fills. When this is the case, this prop will fill the rest of the scrollview with a color to avoid setting a background and creating unnecessary overdraw. This is an advanced optimization that is not needed in the general case.

    scrollEventThrottle
    
+
    This controls how often the scroll event will be fired while scrolling (as a time interval in ms). A lower number yields better accuracy for code that is tracking the scroll position, but can lead to scroll performance problems due to the volume of information being send over the bridge. You will not notice a difference between values set between 1-16 as the JS run loop is synced to the screen refresh rate. If you do not need precise scroll position tracking, set this value higher to limit the information being sent across the bridge. The default value is zero, which results in the scroll event being sent only once each time the view is scrolled.

    Methods
    
+
    scrollTo()
    
+
    scrollTo(([y]: number), object, ([x]: number), ([animated]: boolean));
+
    
+
    Scrolls to a given x, y offset, either immediately or with a smooth animation.
    
+
    Example:
    
+
    scrollTo({x: 0, y: 0, animated: true})
    
+
    Note: The weird function signature is due to the fact that, for historical reasons, the function also accepts separate arguments as an alternative to the options object. This is deprecated due to ambiguity (y before x), and SHOULD NOT BE USED.
    
+
    
+
    scrollToEnd()
    
+
    scrollToEnd(([options]: object));
+
    
+
    If this is a vertical ScrollView scrolls to the bottom. If this is a horizontal ScrollView scrolls to the right.
    
+
    Use scrollToEnd({animated: true}) for smooth animated scrolling, scrollToEnd({animated: false}) for immediate scrolling. If no options are passed, animated defaults to true.
    
+
    
+
    scrollWithoutAnimationTo()

    SectionList
    A performant interface for rendering sectioned lists, supporting the most handy features:
    
+
      
+
    • Fully cross-platform.
      • 
+
    • Configurable viewability callbacks.
      • 
+
    • List header support.
      • 
+
    • List footer support.
      • 
+
    • Item separator support.
      • 
+
    • Section header support.
      • 
+
    • Section separator support.
      • 
+
    • Heterogeneous data and item rendering support.
      • 
+
    • Pull to Refresh.
      • 
+
    • Scroll loading.
      • 
+
    
+
    If you don't need section support and want a simpler interface, use <FlatList>.
    
+
    Simple Examples:
    
+
    // Example 1 (Homogeneous Rendering)
+<SectionList
+  renderItem={({item, index, section}) => <Text key={index}>{item}</Text>}
+  renderSectionHeader={({section: {title}}) => (
+    <Text style={{fontWeight: 'bold'}}>{title}</Text>
+  )}
+  sections={[
+    {title: 'Title1', data: ['item1', 'item2']},
+    {title: 'Title2', data: ['item3', 'item4']},
+    {title: 'Title3', data: ['item5', 'item6']},
+  ]}
+  keyExtractor={(item, index) => item + index}
+/>
+
    
+
    // Example 2 (Heterogeneous Rendering / No Section Headers)
+const overrideRenderItem = ({ item, index, section: { title, data } }) => <Text key={index}>Override{item}</Text>
+
+<SectionList
+  renderItem={({ item, index, section }) => <Text key={index}>{item}</Text>}
+  sections={[
+    { title: 'Title1', data: ['item1', 'item2'], renderItem: overrideRenderItem },
+    { title: 'Title2', data: ['item3', 'item4'] },
+    { title: 'Title3', data: ['item5', 'item6'] },
+  ]}
+/>
+
    
+
    This is a convenience wrapper around <VirtualizedList>, and thus inherits its props (as well as those of <ScrollView> that aren't explicitly listed here, along with the following caveats:
    
+
      
+
    • Internal state is not preserved when content scrolls out of the render window. Make sure all your data is captured in the item data or external stores like Flux, Redux, or Relay.
      • 
+
    • This is a PureComponent which means that it will not re-render if props remain shallow- equal. Make sure that everything your renderItem function depends on is passed as a prop (e.g. extraData) that is not === after updates, otherwise your UI may not update on changes. This includes the data prop and parent component state.
      • 
+
    • In order to constrain memory and enable smooth scrolling, content is rendered asynchronously offscreen. This means it's possible to scroll faster than the fill rate and momentarily see blank content. This is a tradeoff that can be adjusted to suit the needs of each application, and we are working on improving it behind the scenes.
      • 
+
    • By default, the list looks for a key prop on each item and uses that for the React key. Alternatively, you can provide a custom keyExtractor prop.

    keyExtractor
    
+
    Used to extract a unique key for a given item at the specified index. Key is used for caching and as the react key to track item re-ordering. The default extractor checks item.key, then falls back to using the index, like react does. Note that this sets keys for each item, but each overall section still needs its own key.

+
+
+
+
+
+
    TypeRequired
    functionYes
    
+
    The render function will be passed an object with the following keys:

      • 
+
    • 'index' (number) - Item's index within the section.
      • 
+
    • 'section' (object) - The full section object as specified in sections.
      • 
+
    • 'separators' (object) - An object with the following keys:
+
        
+
      • 'highlight' (function) - () => void
        • 
+
      • 'unhighlight' (function) - () => void
        • 
+
      • 'updateProps' (function) - (select, newProps) => void
+
          
+
        • 'select' (enum) - possible values are 'leading', 'trailing'
          •

    SectionList
    A performant interface for rendering sectioned lists, supporting the most handy features:
    
+
      
+
    • Fully cross-platform.
      • 
+
    • Configurable viewability callbacks.
      • 
+
    • List header support.
      • 
+
    • List footer support.
      • 
+
    • Item separator support.
      • 
+
    • Section header support.
      • 
+
    • Section separator support.
      • 
+
    • Heterogeneous data and item rendering support.
      • 
+
    • Pull to Refresh.
      • 
+
    • Scroll loading.
      • 
+
    
+
    If you don't need section support and want a simpler interface, use <FlatList>.
    
+
    Simple Examples:
    
+
    // Example 1 (Homogeneous Rendering)
+<SectionList
+  renderItem={({item, index, section}) => <Text key={index}>{item}</Text>}
+  renderSectionHeader={({section: {title}}) => (
+    <Text style={{fontWeight: 'bold'}}>{title}</Text>
+  )}
+  sections={[
+    {title: 'Title1', data: ['item1', 'item2']},
+    {title: 'Title2', data: ['item3', 'item4']},
+    {title: 'Title3', data: ['item5', 'item6']},
+  ]}
+  keyExtractor={(item, index) => item + index}
+/>
+
    
+
    // Example 2 (Heterogeneous Rendering / No Section Headers)
+const overrideRenderItem = ({ item, index, section: { title, data } }) => <Text key={index}>Override{item}</Text>
+
+<SectionList
+  renderItem={({ item, index, section }) => <Text key={index}>{item}</Text>}
+  sections={[
+    { title: 'Title1', data: ['item1', 'item2'], renderItem: overrideRenderItem },
+    { title: 'Title2', data: ['item3', 'item4'] },
+    { title: 'Title3', data: ['item5', 'item6'] },
+  ]}
+/>
+
    
+
    This is a convenience wrapper around <VirtualizedList>, and thus inherits its props (as well as those of <ScrollView> that aren't explicitly listed here, along with the following caveats:
    
+
      
+
    • Internal state is not preserved when content scrolls out of the render window. Make sure all your data is captured in the item data or external stores like Flux, Redux, or Relay.
      • 
+
    • This is a PureComponent which means that it will not re-render if props remain shallow- equal. Make sure that everything your renderItem function depends on is passed as a prop (e.g. extraData) that is not === after updates, otherwise your UI may not update on changes. This includes the data prop and parent component state.
      • 
+
    • In order to constrain memory and enable smooth scrolling, content is rendered asynchronously offscreen. This means it's possible to scroll faster than the fill rate and momentarily see blank content. This is a tradeoff that can be adjusted to suit the needs of each application, and we are working on improving it behind the scenes.
      • 
+
    • By default, the list looks for a key prop on each item and uses that for the React key. Alternatively, you can provide a custom keyExtractor prop.

    sections
    
+
    The actual data to render, akin to the data prop in FlatList.
    
+
+
+
+
+
+
+
+
    TypeRequired
    array of SectionsYes
    
+
    
+
    initialNumToRender
    
+
    How many items to render in the initial batch. This should be enough to fill the screen but not much more. Note these items will never be unmounted as part of the windowed rendering in order to improve perceived performance of scroll-to-top actions.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberYes
    
+
    
+
    keyExtractor
    
+
    Used to extract a unique key for a given item at the specified index. Key is used for caching and as the react key to track item re-ordering. The default extractor checks item.key, then falls back to using the index, like react does. Note that this sets keys for each item, but each overall section still needs its own key.
    
+
+
+
+
+
+
+
+
    TypeRequired
    (item: Item, index: number) => stringYes
    
+
    
+
    renderItem
    
+
    Default renderer for every item in every section. Can be over-ridden on a per-section basis. Should return a React element.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionYes
    
+
    The render function will be passed an object with the following keys:
    
+
      
+
    • 'item' (object) - the item object as specified in this section's data key
      • 
+
    • 'index' (number) - Item's index within the section.
      • 
+
    • 'section' (object) - The full section object as specified in sections.
      • 
+
    • 'separators' (object) - An object with the following keys:
+
        
+
      • 'highlight' (function) - () => void
        • 
+
      • 'unhighlight' (function) - () => void
        • 
+
      • 'updateProps' (function) - (select, newProps) => void
+
          
+
        • 'select' (enum) - possible values are 'leading', 'trailing'
          •

+
    extraData

+
    Rendered in between each item, but not at the top or bottom. By default, highlighted, section, and [leading/trailing][Item/Separator] props are provided. renderItem provides separators.highlight/unhighlight which will update the highlighted prop, but you can also add custom props with separators.updateProps.

    Programmatically changing selected index
    
+
    The selected index can be changed on the fly by assigning the selectedIndex prop to a state variable, then changing that variable. Note that the state variable would need to be updated as the user selects a value and changes the index, as shown in the example below.

    SegmentedControlIOS
    Use SegmentedControlIOS to render a UISegmentedControl iOS.
    
+
    Programmatically changing selected index
    
+
    The selected index can be changed on the fly by assigning the selectedIndex prop to a state variable, then changing that variable. Note that the state variable would need to be updated as the user selects a value and changes the index, as shown in the example below.
    
+
    Example
    
+
    <SegmentedControlIOS
+  values={['One', 'Two']}
+  selectedIndex={this.state.selectedIndex}
+  onChange={(event) => {
+    this.setState({selectedIndex: event.nativeEvent.selectedSegmentIndex});
+  }}

+Generating Signed APK · React Native
    0.58
    Edit
    Generating Signed APK
    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.
    
+
    Generating a signing key
    
+
    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.
    
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    
+
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
+
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.
    
+
    On Mac, if you're not sure where your jdk bin folder is, then perform the following command to find it:
    
+
    $ /usr/libexec/java_home
+
    
+
    It will output the directory of the jdk, which will look something like this:
    
+
    /Library/Java/JavaVirtualMachines/jdkX.X.X_XXX.jdk/Contents/Home
+
    
+
    Navigate to that directory by using the command $ cd /your/jdk/path and use the keytool command with sudo permission as shown below.
    
+
    $ sudo keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    
+
    Note: Remember to keep your keystore file private and never commit it to version control.
    
+
    Setting up gradle variables
    
+
      
+
    1. Place the my-release-key.keystore file under the android/app directory in your project folder.
      2. 
+
    2. Edit the file ~/.gradle/gradle.properties or android/gradle.properties, and add the following (replace ***** with the correct keystore password, alias and key password),
      3. 
+
    
+
    MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
+MYAPP_RELEASE_KEY_ALIAS=my-key-alias
+MYAPP_RELEASE_STORE_PASSWORD=*****
+MYAPP_RELEASE_KEY_PASSWORD=*****
+
    
+
    These are going to be global gradle variables, which we can later use in our gradle config to sign our app.
    
+
    
+
    Note about saving the keystore:
    
+
    
+
    
+
    Once you publish the app on the Play Store, you will need to republish your app under a different package name (losing all downloads and ratings) if you want to change the signing key at any point. So backup your keystore and don't forget the passwords.
    
+
    
+
    Note about security: If you are not keen on storing your passwords in plaintext, and you are running OSX, you can also store your credentials in the Keychain Access app. Then you can skip the two last rows in ~/.gradle/gradle.properties.
    
+
    Adding signing config to your app's gradle config
    
+
    Edit the file android/app/build.gradle in your project folder, and add the signing config,
    
+
    ...
+android {
+    ...
+    defaultConfig { ... }
+    signingConfigs {
+        release {
+            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
+                storeFile file(MYAPP_RELEASE_STORE_FILE)
+                storePassword MYAPP_RELEASE_STORE_PASSWORD
+                keyAlias MYAPP_RELEASE_KEY_ALIAS
+                keyPassword MYAPP_RELEASE_KEY_PASSWORD
+            }
+        }
+    }
+    buildTypes {
+        release {
+            ...
+            signingConfig signingConfigs.release
+        }
+    }
+}
+...
+
    
+
    Generating the release APK
    
+
    Simply run the following in a terminal:
    
+
    $ cd android
+$ ./gradlew assembleRelease
+
    
+
    Gradle's assembleRelease will bundle all the JavaScript needed to run your app into the APK. If you need to change the way the JavaScript bundle and/or drawable resources are bundled (e.g. if you changed the default file/folder names or the general structure of the project), have a look at android/app/build.gradle to see how you can update it to reflect these changes.
    
+
    
+
    Note: Make sure gradle.properties does not include org.gradle.configureondemand=true as that will make the release build skip bundling JS and assets into the APK.
    
+
    
+
    The generated APK can be found under android/app/build/outputs/apk/release/app-release.apk, and is ready to be distributed.
    
+
    Testing the release build of your app
    
+
    Before uploading the release build to the Play Store, make sure you test it thoroughly. First uninstall any previous version of the app you already have installed. Install it on the device using:
    
+
    $ react-native run-android --variant=release
+
    
+
    Note that --variant=release is only available if you've set up signing as described above.
    
+
    You can kill any running packager instances, since all your framework and JavaScript code is bundled in the APK's assets.
    
+
    Split APKs by ABI to reduce file size
    
+
    By default, the generated APK has the native code for both x86 and ARMv7a CPU architectures. This makes it easier to share APKs that run on almost all Android devices. However, this has the downside that there will be some unused native code on any device, leading to unnecessarily bigger APKs.
    
+
    You can create an APK for each CPU by changing the following line in android/app/build.gradle:
    
+
    - ndk {
+-   abiFilters "armeabi-v7a", "x86"
+- }
+- def enableSeparateBuildPerCPUArchitecture = false
++ def enableSeparateBuildPerCPUArchitecture = true
+
    
+
    Upload both these files to markets which support device targetting, such as Google Play and Amazon AppStore, and the users will automatically get the appropriate APK. If you want to upload to other markets, such as APKFiles, which do not support multiple APKs for a single app, change the following line as well to create the default universal APK with binaries for both CPUs.
    
+
    - universalApk false  // If true, also generate a universal APK
++ universalApk true  // If true, also generate a universal APK
+
    
+
    Enabling Proguard to reduce the size of the APK (optional)
    
+
    Proguard is a tool that can slightly reduce the size of the APK. It does this by stripping parts of the React Native Java bytecode (and its dependencies) that your app is not using.
    
+
    IMPORTANT: Make sure to thoroughly test your app if you've enabled Proguard. Proguard often requires configuration specific to each native library you're using. See app/proguard-rules.pro.
    
+
    To enable Proguard, edit android/app/build.gradle:
    
+
    /**
+ * Run Proguard to shrink the Java bytecode in release builds.
+ */
+def enableProguardInReleaseBuilds = true
+

+Generating Signed APK · React Native

    Edit
    Generating Signed APK
    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.
    
+
    Generating a signing key
    
+
    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.
    
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    
+
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
+
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.
    
+
    On Mac, if you're not sure where your jdk bin folder is, then perform the following command to find it:
    
+
    $ /usr/libexec/java_home
+
    
+
    It will output the directory of the jdk, which will look something like this:
    
+
    /Library/Java/JavaVirtualMachines/jdkX.X.X_XXX.jdk/Contents/Home
+
    
+
    Navigate to that directory by using the command $ cd /your/jdk/path and use the keytool command with sudo permission as shown below.
    
+
    $ sudo keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    
+
    Note: Remember to keep your keystore file private and never commit it to version control.
    
+
    Setting up gradle variables
    
+
      
+
    1. Place the my-release-key.keystore file under the android/app directory in your project folder.
      2. 
+
    2. Edit the file ~/.gradle/gradle.properties or android/gradle.properties, and add the following (replace ***** with the correct keystore password, alias and key password),
      3. 
+
    
+
    MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
+MYAPP_RELEASE_KEY_ALIAS=my-key-alias
+MYAPP_RELEASE_STORE_PASSWORD=*****
+MYAPP_RELEASE_KEY_PASSWORD=*****
+
    
+
    These are going to be global gradle variables, which we can later use in our gradle config to sign our app.
    
+
    
+
    Note about saving the keystore:
    
+
    
+
    
+
    Once you publish the app on the Play Store, you will need to republish your app under a different package name (losing all downloads and ratings) if you want to change the signing key at any point. So backup your keystore and don't forget the passwords.
    
+
    
+
    Note about security: If you are not keen on storing your passwords in plaintext, and you are running OSX, you can also store your credentials in the Keychain Access app. Then you can skip the two last rows in ~/.gradle/gradle.properties.
    
+
    Adding signing config to your app's gradle config
    
+
    Edit the file android/app/build.gradle in your project folder, and add the signing config,
    
+
    ...
+android {
+    ...
+    defaultConfig { ... }
+    signingConfigs {
+        release {
+            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
+                storeFile file(MYAPP_RELEASE_STORE_FILE)
+                storePassword MYAPP_RELEASE_STORE_PASSWORD
+                keyAlias MYAPP_RELEASE_KEY_ALIAS
+                keyPassword MYAPP_RELEASE_KEY_PASSWORD
+            }
+        }
+    }
+    buildTypes {
+        release {
+            ...
+            signingConfig signingConfigs.release
+        }
+    }
+}
+...
+
    
+
    Generating the release APK

    $ cd android
+$ ./gradlew assembleRelease

+State · React Native
    0.58
    Edit
    State
    There are two types of data that control a component: props and state. props are set by the parent and they are fixed throughout the lifetime of a component. For data that is going to change, we have to use state.
    
+
    In general, you should initialize state in the constructor, and then call setState when you want to change it.
    
+
    For example, let's say we want to make text that blinks all the time. The text itself gets set once when the blinking component gets created, so the text itself is a prop. The "whether the text is currently on or off" changes over time, so that should be kept in state.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Text, View } from 'react-native';
+
+class Blink extends Component {
+  constructor(props) {
+    super(props);
+    this.state = { isShowingText: true };
+

    In a real application, you probably won't be setting state with a timer. You might set state when you have new data from the server, or from user input. You can also use a state container like Redux or Mobx to control your data flow. In that case you would use Redux or Mobx to modify your state rather than calling setState directly.
    
+
    When setState is called, BlinkApp will re-render its Component. By calling setState within the Timer, the component will re-render every time the Timer ticks.
    
+
    State works the same way as it does in React, so for more details on handling state, you can look at the React.Component API. At this point, you might be annoyed that most of our examples so far use boring default black text. To make things more beautiful, you will have to learn about Style.

+State · React Native
    0.58
    Edit
    State
    There are two types of data that control a component: props and state. props are set by the parent and they are fixed throughout the lifetime of a component. For data that is going to change, we have to use state.
    
+
    In general, you should initialize state in the constructor, and then call setState when you want to change it.
    
+
    For example, let's say we want to make text that blinks all the time. The text itself gets set once when the blinking component gets created, so the text itself is a prop. The "whether the text is currently on or off" changes over time, so that should be kept in state.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Text, View } from 'react-native';
+
+class Blink extends Component {
+  constructor(props) {
+    super(props);
+    this.state = { isShowingText: true };
+
+    // Toggle the state every second
+    setInterval(() => (
+      this.setState(previousState => (
+        { isShowingText: !previousState.isShowingText }
+      ))
+    ), 1000);
+  }
+
+  render() {
+    if (!this.state.isShowingText) {
+      return null;
+    }
+
+    return (
+      <Text>{this.props.text}</Text>
+    );
+  }
+}
+
+export default class BlinkApp extends Component {
+  render() {
+    return (
+      <View>
+        <Blink text='I love to blink' />
+        <Blink text='Yes blinking is so great' />
+        <Blink text='Why did they ever take this out of HTML' />
+        <Blink text='Look at me look at me look at me' />
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => BlinkApp);
+

    StatusBar
    Component to control the app status bar.
    
+
    Usage with Navigator
    
+
    It is possible to have multiple StatusBar components mounted at the same time. The props will be merged in the order the StatusBar components were mounted.
    
+
    <View>
+  <StatusBar backgroundColor="blue" barStyle="light-content" />

+</View>
+
    
+
    Imperative API
    
+
    For cases where using a component is not ideal, there is also an imperative API exposed as static functions on the component. It is however not recommended to use the static API and the component for the same prop because any value set by the static API will get overriden by the one set by the component in the next render.

    Style
    With React Native, you don't use a special language or syntax for defining styles. You just style your application using JavaScript. All of the core components accept a prop named style. The style names and values usually match how CSS works on the web, except names are written using camel casing, e.g backgroundColor rather than background-color.
    
+
    The style prop can be a plain old JavaScript object. That's the simplest and what we usually use for example code. You can also pass an array of styles - the last style in the array has precedence, so you can use this to inherit styles.
    
+
    As a component grows in complexity, it is often cleaner to use StyleSheet.create to define several styles in one place. Here's an example:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, StyleSheet, Text, View } from 'react-native';
+
+const styles = StyleSheet.create({
+  bigBlue: {
+    color: 'blue',
+    fontWeight: 'bold',
+    fontSize: 30,
+  },
+  red: {
+    color: 'red',
+  },
+});
+
+export default class LotsOfStyles extends Component {
+  render() {
+    return (
+      <View>
+        <Text style={styles.red}>just red</Text>
+        <Text style={styles.bigBlue}>just bigBlue</Text>
+        <Text style={[styles.bigBlue, styles.red]}>bigBlue, then red</Text>
+        <Text style={[styles.red, styles.bigBlue]}>red, then bigBlue</Text>
+      </View>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => LotsOfStyles);
+
    
+
+
    One common pattern is to make your component accept a style prop which in turn is used to style subcomponents. You can use this to make styles "cascade" the way they do in CSS.
    
+
    There are a lot more ways to customize text style. Check out the Text component reference for a complete list.
    
+
    Now you can make your text beautiful. The next step in becoming a style master is to learn how to control component size.

    One common pattern is to make your component accept a style prop which in turn is used to style subcomponents. You can use this to make styles "cascade" the way they do in CSS.
    
+
    There are a lot more ways to customize text style. Check out the Text component reference for a complete list.
    
+
    Now you can make your text beautiful. The next step in becoming a style master is to learn how to control component size.

    StyleSheet
    A StyleSheet is an abstraction similar to CSS StyleSheets
    
+
    Create a new StyleSheet:
    
+
    const styles = StyleSheet.create({
+  container: {
+    borderRadius: 4,
+    borderWidth: 0.5,
+    borderColor: '#d6d7da',
+  },
+  title: {
+    fontSize: 19,
+    fontWeight: 'bold',
+  },
+  activeTitle: {
+    color: 'red',
+  },
+});
+
    
+
    Use a StyleSheet:
    
+
    <View style={styles.container}>
+  <Text style={[styles.title, this.props.isActive && styles.activeTitle]} />
+</View>
+
    
+
    Code quality:
    
+
      
+
    • By moving styles away from the render function, you're making the code easier to understand.
      • 
+
    • Naming the styles is a good way to add meaning to the low level components in the render function.

    WARNING: EXPERIMENTAL. Breaking changes will probably happen a lot and will not be reliably announced. The whole thing might be deleted, who knows? Use at your own risk.
    
+
    Sets a function to use to pre-process a style property value. This is used internally to process color and transform values. You should not use this unless you really know what you are doing and have exhausted other options.
    
+
    
+
    create()
    
+
    static create(obj)
+
    
+
    Creates a StyleSheet style reference from the given object.
    
+
    
+
    flatten
    
+
    static flatten(style)
+
    
+
    Flattens an array of style objects, into one aggregated style object. Alternatively, this method can be used to lookup IDs, returned by StyleSheet.register.
    
+
    
+
    NOTE: Exercise caution as abusing this can tax you in terms of optimizations. IDs enable optimizations through the bridge and memory in general. Refering to style objects directly will deprive you of these optimizations.
    
+
    
+
    Example:
    
+
    var styles = StyleSheet.create({
+  listItem: {
+    flex: 1,
+    fontSize: 16,
+    color: 'white',
+  },
+  selectedListItem: {
+    color: 'green',
+  },
+});
+
+StyleSheet.flatten([styles.listItem, styles.selectedListItem]);
+// returns { flex: 1, fontSize: 16, color: 'green' }
+
    
+
    Alternative use:
    
+
    var styles = StyleSheet.create({
+  listItem: {
+    flex: 1,
+    fontSize: 16,
+    color: 'white',
+  },
+  selectedListItem: {
+    color: 'green',
+  },
+});
+
+StyleSheet.flatten(styles.listItem);
+// returns { flex: 1, fontSize: 16, color: 'white' }
+// Simply styles.listItem would return its ID (number)
+
    
+
    This method internally uses StyleSheetRegistry.getStyleByID(style) to resolve style objects represented by IDs. Thus, an array of style objects (instances of StyleSheet.create()), are individually resolved to, their respective objects, merged as one and then returned. This also explains the alternative use.
    
+
    Properties
    
+
    hairlineWidth
    
+
    var styles = StyleSheet.create({
+  separator: {
+    borderBottomColor: '#bbb',
+    borderBottomWidth: StyleSheet.hairlineWidth,
+  },
+});
+
    
+
    This constant will always be a round number of pixels (so a line defined by it can look crisp) and will try to match the standard width of a thin line on the underlying platform. However, you should not rely on it being a constant size, because on different platforms and screen densities its value may be calculated differently.
    
+
    A line with hairline width may not be visible if your simulator is downscaled.
    
+
    
+
    absoluteFill
    
+
    A very common pattern is to create overlays with position absolute and zero positioning (position: 'absolute', left: 0, right: 0, top: 0, bottom: 0), so absoluteFill can be used for convenience and to reduce duplication of these repeated styles. If you want, absoluteFill can be used to create a customized entry in a StyleSheet, e.g.:
    
+
    const styles = StyleSheet.create({
+  wrapper: {
+    ...StyleSheet.absoluteFill,
+    top: 10,
+    backgroundColor: 'transparent',
+  },

    Measures multiple methods of a class. For example, the following will return the parse and stringify methods of the JSON class: Systrace.measureMethods(JSON, 'JSON', ['parse', 'stringify']);
    
+
    @param object @param objectName @param methodNames Map from method names to method display names.
    
+
    
+
    measure()
    
+
    static measure(objName, fnName, func)
+
    
+
    Returns a profiled version of the input function. For example, you can: JSON.parse = Systrace.measure('JSON', 'parse', JSON.parse);
    
+
    @param objName @param fnName @param {function} func @return {function} replacement function

    Testing your Changes
    This document is about testing your changes to React Native as a contributor. If you're interested in testing a React Native app, check out the React Native Tutorial on the Jest website.
    
+
    The React Native repo has several tests you can run to verify you haven't caused a regression with your PR. These tests are run using Circle, a continuous integration system. Circle will automatically annotate pull requests with the test results.
    
+
    Whenever you are fixing a bug or adding new functionality to React Native, you should add a test that covers it. Depending on the change you're making, there are different types of tests that may be appropriate.
    
+
+
    JavaScript
    
+
    Jest
    
+
    Jest tests are JavaScript-only tests run on the command line with node. You can run the existing React Native jest tests with:
    
+
    $ cd react-native
+$ npm test
+
    
+
    It's a good idea to add a Jest test when you are working on a change that only modifies JavaScript code.
    
+
    The tests themselves live in the __tests__ directories of the files they test. See TouchableHighlight-test.js for a basic example.
    
+
    Flow
    
+
    You should also make sure your code passes Flow tests. These can be run using:
    
+
    $ cd react-native
+$ npm run flow
+
    
+
    Android
    
+
    Unit Tests
    
+
    The Android unit tests do not run in an emulator. They just use a normal Java installation. The default macOS Java install is insufficient, you may need to install Java 8 (JDK8). You can type javac -version in a terminal to see what version you have:
    
+
    $ javac -version
+javac 1.8.0_111
+
    
+
    The version string 1.8.x_xxx corresponds to JDK 8.
    
+
    You also need to install the Buck build tool. Note that brew may not install the version needed to run the tests. For best results, use the same version as the GitHub builds, which can be found in the .circleci folder in the root of the repo.
    
+
    To run the Android unit tests:
    
+
    $ cd react-native
+$ ./scripts/run-android-local-unit-tests.sh
+
    
+
    It's a good idea to add an Android unit test whenever you are working on code that can be tested by Java code alone. The Android unit tests live under ReactAndroid/src/tests, so you can browse through that directory for good examples of tests.
    
+
    Integration Tests
    
+
    To run the integration tests, you need to install the Android NDK. See Prerequisites.
    
+
    You also need to install the Buck build tool.
    
+
    We recommend running the Android integration tests in an emulator, although you can also use a real Android device. It's a good idea to keep the emulator running with a visible window. That way if your tests stall, you can look at the emulator to debug.
    
+
    Some devices and some emulator configurations may not work with the tests. We do maintain an emulator configuration that works, as the standard for testing. To run this emulator config:
    
+
    $ cd react-native
+$ ./scripts/run-android-emulator.sh
+
    
+
    Once you have an emulator running, to run the integration tests:
    
+
    $ cd react-native
+$ ./scripts/run-android-local-integration-tests.sh
+
    
+
    The integration tests should only take a few minutes to run on a modern developer machine.
    
+
    It's a good idea to add an Android integration test whenever you are working on code that needs both JavaScript and Java to be tested in conjunction. The Android integration tests live under ReactAndroid/src/androidTest, so you can browse through that directory for good examples of tests.
    
+
    iOS
    
+
    Integration Tests
    
+
    React Native provides facilities to make it easier to test integrated components that require both native and JS components to communicate across the bridge. The two main components are RCTTestRunner and RCTTestModule. RCTTestRunner sets up the ReactNative environment and provides facilities to run the tests as XCTestCases in Xcode (runTest:module is the simplest method). RCTTestModule is exported to JS as NativeModules.TestModule.
    
+
    The tests themselves are written in JS, and must call TestModule.markTestCompleted() when they are done, otherwise the test will timeout and fail. Test failures are primarily indicated by throwing a JS exception. It is also possible to test error conditions with runTest:module:initialProps:expectErrorRegex: or runTest:module:initialProps:expectErrorBlock: which will expect an error to be thrown and verify the error matches the provided criteria.
    
+
    See the following for example usage and integration points:
    
+
+
    You can run integration tests locally with cmd+U in the IntegrationTest and RNTester apps in Xcode, or by running the following in the command line on macOS:
    
+
    $ cd react-native
+$ ./scripts/objc-test-ios.sh
+
    
+
    
+
    Your Xcode install will come with a variety of Simulators running the latest OS. You may need to manually create a new Simulator to match what the XCODE_DESTINATION param in the test script.
    
+
    
+
    Screenshot/Snapshot Tests
    
+
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
+
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.
    
+
    Automated End-to-End Tests
    
+
    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.
    
+
    You can run Detox end-to-end tests locally by installing the Detox CLI on macOS, then running the following in the command line:
    
+
    $ cd react-native
+$ npm run build-ios-e2e
+$ npm run test-ios-e2e
+
    
+
    If you work on a component or API that isn't convered by a Detox test, please consider adding one. Detox tests are stored under RNTester/e2e/__tests__.
    
+
    Apple TV
    
+
    The same tests discussed above for iOS will also run on tvOS. In the RNTester Xcode project, select the RNTester-tvOS target, and you can follow the same steps above to run the tests in Xcode.
    
+
    You can run Apple TV unit and integration tests locally by running the following in the command line on macOS:
    
+
    $ cd react-native
+$ ./scripts/objc-test-tvos.sh (make sure the line `TEST="test"` is uncommented)
+
    
+
    Manual end-to-end tests
    
+
    Finally, make sure manual end-to-end tests run successfully by executing the following script:
    
+
    $ cd react-native
+$ ./scripts/test-manual-e2e.sh
+
    
+
    Updating the Documentation
    
+
    If you are adding new functionality or introducing a change in behavior, we will ask you to update the documentation to reflect your changes. The docs are hosted as part of the React Native website. The website itself is hosted on GitHub Pages and is automatically generated from the Markdown sources.
    
+
    To update the documentation, you will need to clone the facebook/react-native-website repository, make your changes in the docs/ directory, and then send a pull request. For lightweight changes to a single file, you may also click on "Edit" at the top of any doc right here on the website.

    Jest tests are JavaScript-only tests run on the command line with node. You can run the existing React Native jest tests with:
    
+
    $ cd react-native
+$ npm test
+
    
+
    It's a good idea to add a Jest test when you are working on a change that only modifies JavaScript code.
    
+
    The tests themselves live in the __tests__ directories of the files they test. See TouchableHighlight-test.js for a basic example.
    
+
    Flow
    
+
    You should also make sure your code passes Flow tests. These can be run using:
    
+
    $ cd react-native
+$ npm run flow
+
    
+
    Android
    
+
    Unit Tests
    
+
    The Android unit tests do not run in an emulator. They just use a normal Java installation. The default macOS Java install is insufficient, you may need to install Java 8 (JDK8). You can type javac -version in a terminal to see what version you have:
    
+
    $ javac -version
+javac 1.8.0_111
+
    
+
    The version string 1.8.x_xxx corresponds to JDK 8.
    
+
    You also need to install the Buck build tool. Note that brew may not install the version needed to run the tests. For best results, use the same version as the GitHub builds, which can be found in the .circleci folder in the root of the repo.
    
+
    To run the Android unit tests:
    
+
    $ cd react-native
+$ ./scripts/run-android-local-unit-tests.sh
+
    
+
    It's a good idea to add an Android unit test whenever you are working on code that can be tested by Java code alone. The Android unit tests live under ReactAndroid/src/tests, so you can browse through that directory for good examples of tests.
    
+
    Integration Tests
    
+
    To run the integration tests, you need to install the Android NDK. See Prerequisites.
    
+
    You also need to install the Buck build tool.
    
+
    We recommend running the Android integration tests in an emulator, although you can also use a real Android device. It's a good idea to keep the emulator running with a visible window. That way if your tests stall, you can look at the emulator to debug.
    
+
    Some devices and some emulator configurations may not work with the tests. We do maintain an emulator configuration that works, as the standard for testing. To run this emulator config:
    
+
    $ cd react-native
+$ ./scripts/run-android-emulator.sh
+
    
+
    Once you have an emulator running, to run the integration tests:
    
+
    $ cd react-native
+$ ./scripts/run-android-local-integration-tests.sh
+
    
+
    The integration tests should only take a few minutes to run on a modern developer machine.
    
+
    It's a good idea to add an Android integration test whenever you are working on code that needs both JavaScript and Java to be tested in conjunction. The Android integration tests live under ReactAndroid/src/androidTest, so you can browse through that directory for good examples of tests.
    
+
    iOS
    
+
    Integration Tests
    
+
    React Native provides facilities to make it easier to test integrated components that require both native and JS components to communicate across the bridge. The two main components are RCTTestRunner and RCTTestModule. RCTTestRunner sets up the ReactNative environment and provides facilities to run the tests as XCTestCases in Xcode (runTest:module is the simplest method). RCTTestModule is exported to JS as NativeModules.TestModule.
    
+
    The tests themselves are written in JS, and must call TestModule.markTestCompleted() when they are done, otherwise the test will timeout and fail. Test failures are primarily indicated by throwing a JS exception. It is also possible to test error conditions with runTest:module:initialProps:expectErrorRegex: or runTest:module:initialProps:expectErrorBlock: which will expect an error to be thrown and verify the error matches the provided criteria.
    
+
    See the following for example usage and integration points:
    
+
+
    You can run integration tests locally with cmd+U in the IntegrationTest and RNTester apps in Xcode, or by running the following in the command line on macOS:
    
+
    $ cd react-native
+$ ./scripts/objc-test-ios.sh
+
    
+
    
+
    Your Xcode install will come with a variety of Simulators running the latest OS. You may need to manually create a new Simulator to match what the XCODE_DESTINATION param in the test script.
    
+
    
+
    Screenshot/Snapshot Tests
    
+
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
+
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.
    
+
    Automated End-to-End Tests
    
+
    End-to-end tests written in Detox confirm that React Native components and APIs function correctly in the context of a running app. They run the RNTester app in the simulator and simulate a user interacting with the app.
    
+
    You can run Detox end-to-end tests locally by installing the Detox CLI on macOS, then running the following in the command line:
    
+
    $ cd react-native
+$ npm run build-ios-e2e
+$ npm run test-ios-e2e
+
    
+
    If you work on a component or API that isn't convered by a Detox test, please consider adding one. Detox tests are stored under RNTester/e2e/__tests__.
    
+
    Apple TV
    
+
    The same tests discussed above for iOS will also run on tvOS. In the RNTester Xcode project, select the RNTester-tvOS target, and you can follow the same steps above to run the tests in Xcode.
    
+
    You can run Apple TV unit and integration tests locally by running the following in the command line on macOS:
    
+
    $ cd react-native
+$ ./scripts/objc-test-tvos.sh (make sure the line `TEST="test"` is uncommented)
+
    
+
    Manual end-to-end tests
    
+
    Finally, make sure manual end-to-end tests run successfully by executing the following script:
    
+
    $ cd react-native
+$ ./scripts/test-manual-e2e.sh
+
    
+
    Updating the Documentation
    
+
    If you are adding new functionality or introducing a change in behavior, we will ask you to update the documentation to reflect your changes. The docs are hosted as part of the React Native website. The website itself is hosted on GitHub Pages and is automatically generated from the Markdown sources.
    
+
    To update the documentation, you will need to clone the facebook/react-native-website repository, make your changes in the docs/ directory, and then send a pull request. For lightweight changes to a single file, you may also click on "Edit" at the top of any doc right here on the website.

+Text · React Native

    Edit
    Text
    A React component for displaying text.
    
+
    Text supports nesting, styling, and touch handling.
    
+
    In the following example, the nested title and body text will inherit the fontFamily from styles.baseText, but the title provides its own additional styles. The title and body will stack on top of each other on account of the literal newlines:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Text, StyleSheet } from 'react-native';
+
+export default class TextInANest extends Component {
+  constructor(props) {
+    super(props);
+    this.state = {
+      titleText: "Bird's Nest",
+      bodyText: 'This is not really a bird nest.'
+    };
+  }
+
+  render() {
+    return (
+      <Text style={styles.baseText}>
+        <Text style={styles.titleText} onPress={this.onPressTitle}>
+          {this.state.titleText}{'\n'}{'\n'}
+        </Text>
+        <Text numberOfLines={5}>
+          {this.state.bodyText}
+        </Text>
+      </Text>
+    );
+  }
+}
+
+const styles = StyleSheet.create({
+  baseText: {
+    fontFamily: 'Cochin',
+  },
+  titleText: {
+    fontSize: 20,
+    fontWeight: 'bold',
+  },
+});
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('TextInANest', () => TextInANest);
+
    
+
+
    Nested text
    
+
    Both iOS and Android allow you to display formatted text by annotating ranges of a string with specific formatting like bold or colored text (NSAttributedString on iOS, SpannableString on Android). In practice, this is very tedious. For React Native, we decided to use web paradigm for this where you can nest text to achieve the same effect.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Text } from 'react-native';
+
+export default class BoldAndBeautiful extends Component {
+  render() {
+    return (
+      <Text style={{fontWeight: 'bold'}}>
+        I am bold
+        <Text style={{color: 'red'}}>
+          and red
+        </Text>
+      </Text>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => BoldAndBeautiful);
+
    
+
+
    Behind the scenes, React Native converts this to a flat NSAttributedString or SpannableString that contains the following information:
    
+
    "I am bold and red"
+0-9: bold
+9-17: bold, red
+
    
+
    Containers
    
+
    The <Text> element is special relative to layout: everything inside is no longer using the flexbox layout but using text layout. This means that elements inside of a <Text> are no longer rectangles, but wrap when they see the end of the line.
    
+
    <Text>
+  <Text>First part and </Text>
+  <Text>second part</Text>
+</Text>
+// Text container: the text will be inline if the space allowed it
+// |First part and second part|
+
+// otherwise, the text will flow as if it was one
+// |First part |
+// |and second |
+// |part       |
+
+<View>
+  <Text>First part and </Text>
+  <Text>second part</Text>
+</View>
+// View container: each text is its own block
+// |First part and|
+// |second part   |
+
+// the will will flow in its own block
+// |First part |
+// |and        |
+// |second part|
+
    
+
    Limited Style Inheritance
    
+
    On the web, the usual way to set a font family and size for the entire document is to take advantage of inherited CSS properties like so:
    
+
    html {
+  font-family: 'lucida grande', tahoma, verdana, arial, sans-serif;
+  font-size: 11px;
+  color: #141823;
+}
+
    
+
    All elements in the document will inherit this font unless they or one of their parents specifies a new rule.
    
+
    In React Native, we are more strict about it: you must wrap all the text nodes inside of a <Text> component. You cannot have a text node directly under a <View>.
    
+
    // BAD: will raise exception, can't have a text node as child of a <View>
+<View>
+  Some text
+</View>
+
+// GOOD
+<View>
+  <Text>
+    Some text
+  </Text>
+</View>
+
    
+
    You also lose the ability to set up a default font for an entire subtree. The recommended way to use consistent fonts and sizes across your application is to create a component MyAppText that includes them and use this component across your app. You can also use this component to make more specific components like MyAppHeaderText for other kinds of text.
    
+
    <View>
+  <MyAppText>
+    Text styled with the default font for the entire application
+  </MyAppText>
+  <MyAppHeaderText>Text styled as a header</MyAppHeaderText>
+</View>
+
    
+
    Assuming that MyAppText is a component that simply renders out its children into a Text component with styling, then MyAppHeaderText can be defined as follows:
    
+
    class MyAppHeaderText extends Component {
+  render() {
+    return (
+      <MyAppText>
+        <Text style={{fontSize: 20}}>{this.props.children}</Text>
+      </MyAppText>
+    );
+  }
+}
+
    
+
    Composing MyAppText in this way ensures that we get the styles from a top-level component, but leaves us the ability to add / override them in specific use cases.
    
+
    React Native still has the concept of style inheritance, but limited to text subtrees. In this case, the second part will be both bold and red.
    
+
    <Text style={{fontWeight: 'bold'}}>
+  I am bold
+  <Text style={{color: 'red'}}>and red</Text>
+</Text>
+
    
+
    We believe that this more constrained way to style text will yield better apps:

    Text
    A React component for displaying text.
    
+
    Text supports nesting, styling, and touch handling.
    
+
    In the following example, the nested title and body text will inherit the fontFamily from styles.baseText, but the title provides its own additional styles. The title and body will stack on top of each other on account of the literal newlines:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Text, StyleSheet } from 'react-native';
+
+export default class TextInANest extends Component {
+  constructor(props) {
+    super(props);
+    this.state = {
+      titleText: "Bird's Nest",
+      bodyText: 'This is not really a bird nest.'
+    };
+  }
+
+  render() {
+    return (
+      <Text style={styles.baseText}>
+        <Text style={styles.titleText} onPress={this.onPressTitle}>
+          {this.state.titleText}{'\n'}{'\n'}
+        </Text>
+        <Text numberOfLines={5}>
+          {this.state.bodyText}
+        </Text>
+      </Text>
+    );
+  }
+}
+
+const styles = StyleSheet.create({
+  baseText: {
+    fontFamily: 'Cochin',
+  },
+  titleText: {
+    fontSize: 20,
+    fontWeight: 'bold',
+  },
+});
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('TextInANest', () => TextInANest);
+
    
+
+
    Nested text
    
+
    Both iOS and Android allow you to display formatted text by annotating ranges of a string with specific formatting like bold or colored text (NSAttributedString on iOS, SpannableString on Android). In practice, this is very tedious. For React Native, we decided to use web paradigm for this where you can nest text to achieve the same effect.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, Text } from 'react-native';
+
+export default class BoldAndBeautiful extends Component {
+  render() {
+    return (
+      <Text style={{fontWeight: 'bold'}}>
+        I am bold
+        <Text style={{color: 'red'}}>
+          and red
+        </Text>
+      </Text>
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => BoldAndBeautiful);
+
    
+
+
    Behind the scenes, React Native converts this to a flat NSAttributedString or SpannableString that contains the following information:
    
+
    "I am bold and red"
+0-9: bold
+9-17: bold, red
+
    
+
    Containers
    
+
    The <Text> element is special relative to layout: everything inside is no longer using the flexbox layout but using text layout. This means that elements inside of a <Text> are no longer rectangles, but wrap when they see the end of the line.
    
+
    <Text>
+  <Text>First part and </Text>
+  <Text>second part</Text>
+</Text>
+// Text container: the text will be inline if the space allowed it
+// |First part and second part|
+
+// otherwise, the text will flow as if it was one
+// |First part |
+// |and second |
+// |part       |
+
+<View>
+  <Text>First part and </Text>
+  <Text>second part</Text>
+</View>
+// View container: each text is its own block
+// |First part and|
+// |second part   |
+
+// the will will flow in its own block
+// |First part |
+// |and        |
+// |second part|
+
    
+
    Limited Style Inheritance
    
+
    On the web, the usual way to set a font family and size for the entire document is to take advantage of inherited CSS properties like so:
    
+
    html {
+  font-family: 'lucida grande', tahoma, verdana, arial, sans-serif;
+  font-size: 11px;
+  color: #141823;
+}
+
    
+
    All elements in the document will inherit this font unless they or one of their parents specifies a new rule.
    
+
    In React Native, we are more strict about it: you must wrap all the text nodes inside of a <Text> component. You cannot have a text node directly under a <View>.
    
+
    // BAD: will raise exception, can't have a text node as child of a <View>
+<View>
+  Some text
+</View>
+
+// GOOD
+<View>
+  <Text>
+    Some text
+  </Text>
+</View>
+
    
+
    You also lose the ability to set up a default font for an entire subtree. The recommended way to use consistent fonts and sizes across your application is to create a component MyAppText that includes them and use this component across your app. You can also use this component to make more specific components like MyAppHeaderText for other kinds of text.
    
+
    <View>
+  <MyAppText>
+    Text styled with the default font for the entire application
+  </MyAppText>
+  <MyAppHeaderText>Text styled as a header</MyAppHeaderText>
+</View>
+
    
+
    Assuming that MyAppText is a component that simply renders out its children into a Text component with styling, then MyAppHeaderText can be defined as follows:
    
+
    class MyAppHeaderText extends Component {
+  render() {
+    return (
+      <MyAppText>
+        <Text style={{fontSize: 20}}>{this.props.children}</Text>
+      </MyAppText>
+    );
+  }
+}
+
    
+
    Composing MyAppText in this way ensures that we get the styles from a top-level component, but leaves us the ability to add / override them in specific use cases.
    
+
    React Native still has the concept of style inheritance, but limited to text subtrees. In this case, the second part will be both bold and red.
    
+
    <Text style={{fontWeight: 'bold'}}>
+  I am bold
+  <Text style={{color: 'red'}}>and red</Text>
+</Text>
+
    
+
    We believe that this more constrained way to style text will yield better apps:
    
+
      
+

    TextInput
    A foundational component for inputting text into the app via a keyboard. Props provide configurability for several features, such as auto-correction, auto-capitalization, placeholder text, and different keyboard types, such as a numeric keypad.
    
+
    The simplest use case is to plop down a TextInput and subscribe to the onChangeText events to read the user input. There are also other events, such as onSubmitEditing and onFocus that can be subscribed to. A simple example:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, TextInput } from 'react-native';
+
+export default class UselessTextInput extends Component {
+  constructor(props) {
+    super(props);
+    this.state = { text: 'Useless Placeholder' };
+  }
+
+  render() {
+    return (
+      <TextInput
+        style={{height: 40, borderColor: 'gray', borderWidth: 1}}
+        onChangeText={(text) => this.setState({text})}
+        value={this.state.text}
+      />
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);
+
    
+
+
    Two methods exposed via the native element are .focus() and .blur() that will focus or blur the TextInput programmatically.
    
+
    Note that some props are only available with multiline={true/false}. Additionally, border styles that apply to only one side of the element (e.g., borderBottomColor, borderLeftWidth, etc.) will not be applied if multiline=false. To achieve the same effect, you can wrap your TextInput in a View:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View, TextInput } from 'react-native';
+
+class UselessTextInput extends Component {
+  render() {
+    return (
+      <TextInput
+        {...this.props} // Inherit any props passed to it; e.g., multiline, numberOfLines below
+        editable = {true}
+        maxLength = {40}
+      />
+    );
+  }
+}
+
+export default class UselessTextInputMultiline extends Component {
+  constructor(props) {
+    super(props);
+    this.state = {
+      text: 'Useless Multiline Placeholder',
+    };
+  }
+
+  // If you type something in the text box that is a color, the background will change to that
+  // color.
+  render() {
+    return (
+     <View style={{
+       backgroundColor: this.state.text,
+       borderBottomColor: '#000000',
+       borderBottomWidth: 1 }}
+     >
+       <UselessTextInput
+         multiline = {true}
+         numberOfLines = {4}
+         onChangeText={(text) => this.setState({text})}
+         value={this.state.text}
+       />
+     </View>
+    );
+  }
+}
+
+// skip these lines if using Create React Native App
+AppRegistry.registerComponent(
+ 'AwesomeProject',
+ () => UselessTextInputMultiline
+);
+
    
+
+
    TextInput has by default a border at the bottom of its view. This border has its padding set by the background image provided by the system, and it cannot be changed. Solutions to avoid this is to either not set height explicitly, case in which the system will take care of displaying the border in the correct position, or to not display the border by setting underlineColorAndroid to transparent.
    
+
    Note that on Android performing text selection in input can change app's activity windowSoftInputMode param to adjustResize. This may cause issues with components that have position: 'absolute' while keyboard is active. To avoid this behavior either specify windowSoftInputMode in AndroidManifest.xml ( https://developer.android.com/guide/topics/manifest/activity-element.html ) or control this param programmatically with native code.

    autoCapitalize
    
+
    Can tell TextInput to automatically capitalize certain characters. This property is not supported by some keyboard types such as name-phone-pad.
    
+
      
+
    • characters: all characters.
      • 
+
    • words: first letter of each word.
      •

+
    autoComplete
    
+
    Specifies autocomplete hints for the system, so it can provide autofill. On Android, the system will aways attempt to offer autofill by using heuristics to identify the type of content. To disable autocomplete, set autoComplete to off.
    
+
    Possible values for autoComplete are:
    
+
      
+
    • off

In addition to simply setting the same value, either set editable={false}, or set/update maxLength to prevent unwanted edits without flicker.

    TextInput
    A foundational component for inputting text into the app via a keyboard. Props provide configurability for several features, such as auto-correction, auto-capitalization, placeholder text, and different keyboard types, such as a numeric keypad.
    
+
    The simplest use case is to plop down a TextInput and subscribe to the onChangeText events to read the user input. There are also other events, such as onSubmitEditing and onFocus that can be subscribed to. A simple example:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, TextInput } from 'react-native';
+
+export default class UselessTextInput extends Component {
+  constructor(props) {
+    super(props);
+    this.state = { text: 'Useless Placeholder' };
+  }
+
+  render() {
+    return (
+      <TextInput
+        style={{height: 40, borderColor: 'gray', borderWidth: 1}}
+        onChangeText={(text) => this.setState({text})}
+        value={this.state.text}
+      />
+    );
+  }
+}
+
+// skip this line if using Create React Native App
+AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);
+
    
+
+
    Two methods exposed via the native element are .focus() and .blur() that will focus or blur the TextInput programmatically.
    
+
    Note that some props are only available with multiline={true/false}. Additionally, border styles that apply to only one side of the element (e.g., borderBottomColor, borderLeftWidth, etc.) will not be applied if multiline=false. To achieve the same effect, you can wrap your TextInput in a View:
    
+
    import React, { Component } from 'react';
+import { AppRegistry, View, TextInput } from 'react-native';
+
+class UselessTextInput extends Component {
+  render() {
+    return (
+      <TextInput
+        {...this.props} // Inherit any props passed to it; e.g., multiline, numberOfLines below
+        editable = {true}
+        maxLength = {40}
+      />
+    );
+  }
+}
+
+export default class UselessTextInputMultiline extends Component {
+  constructor(props) {
+    super(props);
+    this.state = {
+      text: 'Useless Multiline Placeholder',
+    };
+  }
+
+  // If you type something in the text box that is a color, the background will change to that
+  // color.
+  render() {
+    return (
+     <View style={{
+       backgroundColor: this.state.text,
+       borderBottomColor: '#000000',
+       borderBottomWidth: 1 }}
+     >
+       <UselessTextInput
+         multiline = {true}
+         numberOfLines = {4}
+         onChangeText={(text) => this.setState({text})}
+         value={this.state.text}
+       />
+     </View>
+    );
+  }
+}
+
+// skip these lines if using Create React Native App
+AppRegistry.registerComponent(
+ 'AwesomeProject',
+ () => UselessTextInputMultiline
+);
+
    
+
+
    TextInput has by default a border at the bottom of its view. This border has its padding set by the background image provided by the system, and it cannot be changed. Solutions to avoid this is to either not set height explicitly, case in which the system will take care of displaying the border in the correct position, or to not display the border by setting underlineColorAndroid to transparent.
    
+
    Note that on Android performing text selection in input can change app's activity windowSoftInputMode param to adjustResize. This may cause issues with components that have position: 'absolute' while keyboard is active. To avoid this behavior either specify windowSoftInputMode in AndroidManifest.xml ( https://developer.android.com/guide/topics/manifest/activity-element.html ) or control this param programmatically with native code.

+
      
+
    • characters: all characters.
      • 
+
    • words: first letter of each word.

    value

    The value to show for the text input. TextInput is a controlled component, which means the native value will be forced to match this value prop if provided. For most uses, this works great, but in some cases this may cause flickering - one common cause is preventing edits by keeping value the same. In addition to simply setting the same value, either set editable={false}, or set/update maxLength to prevent unwanted edits without flicker.

    requestAnimationFrame(fn) is not the same as setTimeout(fn, 0) - the former will fire after all the frame has flushed, whereas the latter will fire as quickly as possible (over 1000x per second on a iPhone 5S).
    
+
    setImmediate is executed at the end of the current JavaScript execution block, right before sending the batched response back to native. Note that if you call setImmediate within a setImmediate callback, it will be executed right away, it won't yield back to native in between.
    
+
    The Promise implementation uses setImmediate as its asynchronicity primitive.
    
+
    InteractionManager
    
+
    One reason why well-built native apps feel so smooth is by avoiding expensive operations during interactions and animations. In React Native, we currently have a limitation that there is only a single JS execution thread, but you can use InteractionManager to make sure long-running work is scheduled to start after any interactions/animations have completed.
    
+
    Applications can schedule tasks to run after interactions with the following:
    
+
    InteractionManager.runAfterInteractions(() => {
+  // ...long-running synchronous task...
+});
+
    
+
    Compare this to other scheduling alternatives:
    
+
      
+
    • requestAnimationFrame(): for code that animates a view over time.
      • 
+
    • setImmediate/setTimeout/setInterval(): run code later, note this may delay animations.
      • 
+
    • runAfterInteractions(): run code later, without delaying active animations.
      • 
+
    
+
    The touch handling system considers one or more active touches to be an 'interaction' and will delay runAfterInteractions() callbacks until all touches have ended or been cancelled.
    
+
    InteractionManager also allows applications to register animations by creating an interaction 'handle' on animation start, and clearing it upon completion:
    
+
    var handle = InteractionManager.createInteractionHandle();
+// run animation... (`runAfterInteractions` tasks are queued)
+// later, on animation completion:
+InteractionManager.clearInteractionHandle(handle);
+// queued tasks run if all handles were cleared
+
    
+
    TimerMixin
    
+
    We found out that the primary cause of fatals in apps created with React Native was due to timers firing after a component was unmounted. To solve this recurring issue, we introduced TimerMixin. If you include TimerMixin, then you can replace your calls to setTimeout(fn, 500) with this.setTimeout(fn, 500) (just prepend this.) and everything will be properly cleaned up for you when the component unmounts.
    
+
    This library does not ship with React Native - in order to use it on your project, you will need to install it with npm i react-timer-mixin --save from your project directory.
    
+
    import TimerMixin from 'react-timer-mixin';
+
+var Component = createReactClass({
+  mixins: [TimerMixin],
+  componentDidMount: function() {
+    this.setTimeout(() => {
+      console.log('I do not leak!');
+    }, 500);
+  },
+});
+
    
+
    This will eliminate a lot of hard work tracking down bugs, such as crashes caused by timeouts firing after a component has been unmounted.
    
+
    Keep in mind that if you use ES6 classes for your React components there is no built-in API for mixins. To use TimerMixin with ES6 classes, we recommend react-mixin.

    ToastAndroid
    This exposes the native ToastAndroid module as a JS module. This has a function 'show' which takes the following parameters:
    
+
      
+
    1. String message: A string with the text to toast
      2. 
+
    2. int duration: The duration of the toast. May be ToastAndroid.SHORT or ToastAndroid.LONG
      3. 
+
    
+
    There is also a function showWithGravity to specify the layout gravity. May be ToastAndroid.TOP, ToastAndroid.BOTTOM, ToastAndroid.CENTER.
    
+
    The 'showWithGravityAndOffset' function adds on the ability to specify offset These offset values will translate to pixels.
    
+
    Basic usage:
    
+
    import {ToastAndroid} from 'react-native';
+
+ToastAndroid.show('A pikachu appeared nearby !', ToastAndroid.SHORT);
+ToastAndroid.showWithGravity(
+  'All Your Base Are Belong To Us',
+  ToastAndroid.SHORT,
+  ToastAndroid.CENTER,
+);
+ToastAndroid.showWithGravityAndOffset(
+  'A wild toast appeared!',
+  ToastAndroid.LONG,
+  ToastAndroid.BOTTOM,
+  25,
+  50,
+);
+
    
+
    Advanced usage:
    
+
    The ToastAndroid API is imperative and this might present itself as an issue, but there is actually a way(hack) to expose a declarative component from it. See an example below:
    
+
    import React, {Component} from 'react';

    ToolbarAndroid
    React component that wraps the Android-only Toolbar widget. A Toolbar can display a logo, navigation icon (e.g. hamburger menu), a title & subtitle and a list of actions. The title and subtitle are expanded so the logo and navigation icons are displayed on the left, title and subtitle in the middle and the actions on the right.
    
+
    If the toolbar has an only child, it will be displayed between the title and actions.
    
+
    Although the Toolbar supports remote images for the logo, navigation and action icons, this should only be used in DEV mode where require('./some_icon.png') translates into a packager URL. In release mode you should always use a drawable resource for these icons. Using require('./some_icon.png') will do this automatically for you, so as long as you don't explicitly use e.g. {uri: 'http://...'}, you will be good.
    
+
    Example:
    
+
    render: function() {
+  return (
+    <ToolbarAndroid
+      logo={require('./app_logo.png')}
+      title="AwesomeApp"
+      actions={[{title: 'Settings', icon: require('./icon_settings.png'), show: 'always'}]}
+      onActionSelected={this.onActionSelected} />
+  )
+},
+onActionSelected: function(position) {
+  if (position === 0) { // index of 'Settings'
+    showSettings();
+  }
+}

+
    overflowIcon
    
+
    Sets the overflow icon.
    
+
+
+
+
+
+
+
+
    TypeRequired
    optionalImageSourceNo
    
+
    
+
    actions
    
+
    Sets possible actions on the toolbar as part of the action menu. These are displayed as icons or text on the right side of the widget. If they don't fit they are placed in an 'overflow' menu.
    
+
    This property takes an array of objects, where each object has the following keys:
    
+
      
+
    • title: required, the title of this action
      • 
+
    • icon: the icon for this action, e.g. require('./some_icon.png')
      • 
+
    • show: when to show this action as an icon or hide it in the overflow menu: always, ifRoom or never
      • 
+
    • showWithText: boolean, whether to show text alongside the icon or not
      • 
+
    
+
+
+
+
+
+
+
+
    TypeRequired
    array of object: {title: string,icon: optionalImageSource,show: enum('always', 'ifRoom', 'never'),showWithText: bool}No
    
+
    
+
    contentInsetStart
    
+
    Sets the content inset for the toolbar starting edge.
    
+
    The content inset affects the valid area for Toolbar content other than the navigation button and menu. Insets define the minimum margin for these components and can be used to effectively align Toolbar content along well-known gridlines.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberNo
    
+
    
+
    logo
    
+
    Sets the toolbar logo.
    
+
+
+
+
+
+
+
+
    TypeRequired
    optionalImageSourceNo
    
+
    
+
    navIcon
    
+
    Sets the navigation icon.
    
+
+
+
+
+
+
+
+
    TypeRequired
    optionalImageSourceNo
    
+
    
+
    onActionSelected
    
+
    Callback that is called when an action is selected. The only argument that is passed to the callback is the position of the action in the actions array.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onIconClicked
    
+
    Callback called when the icon is selected.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    contentInsetEnd
    
+
    Sets the content inset for the toolbar ending edge.
    
+
    The content inset affects the valid area for Toolbar content other than the navigation button and menu. Insets define the minimum margin for these components and can be used to effectively align Toolbar content along well-known gridlines.
    
+
+
+
+
+
+
+
+
    TypeRequired
    numberNo
    
+
    
+
    rtl
    
+
    Used to set the toolbar direction to RTL. In addition to this property you need to add
    
+
    android:supportsRtl="true"
    
+
    to your application AndroidManifest.xml and then call setLayoutDirection(LayoutDirection.RTL) in your MainActivity onCreate method.

    TouchableHighlight
    A wrapper for making views respond properly to touches. On press down, the opacity of the wrapped view is decreased, which allows the underlay color to show through, darkening or tinting the view.
    
+
    The underlay comes from wrapping the child in a new View, which can affect layout, and sometimes cause unwanted visual artifacts if not used correctly, for example if the backgroundColor of the wrapped view isn't explicitly set to an opaque color.
    
+
    TouchableHighlight must have one child (not zero or more than one). If you wish to have several child components, wrap them in a View.
    
+
    Example:
    
+
    renderButton: function() {
+  return (
+    <TouchableHighlight onPress={this._onPressButton}>
+      <Image
+        style={styles.button}

    TouchableNativeFeedback
    A wrapper for making views respond properly to touches (Android only). On Android this component uses native state drawable to display touch feedback.
    
+
    At the moment it only supports having a single View instance as a child node, as it's implemented by replacing that View with another instance of RCTView node with some additional properties set.
    
+
    Background drawable of native feedback touchable can be customized with background property.
    
+
    Example:
    
+
    renderButton: function() {
+  return (
+    <TouchableNativeFeedback
+        onPress={this._onPressButton}
+        background={TouchableNativeFeedback.SelectableBackground()}>

    background

    Determines the type of background drawable that's going to be used to display feedback. It takes an object with type property and extra data depending on the type. It's recommended to use one of the static methods to generate that dictionary.

    Set to true to add the ripple effect to the foreground of the view, instead of the background. This is useful if one of your child views has a background of its own, or you're e.g. displaying images, and you don't want the ripple to be covered by them.

    Check TouchableNativeFeedback.canUseNativeForeground() first, as this is only available on Android 6.0 and above. If you try to use this on older versions you will get a warning and fallback to background.

    TouchableOpacity
    A wrapper for making views respond properly to touches. On press down, the opacity of the wrapped view is decreased, dimming it.
    
+
    Opacity is controlled by wrapping the children in an Animated.View, which is added to the view hierarchy. Be aware that this can affect layout.
    
+
    Example:
    
+
    renderButton: function() {
+  return (
+    <TouchableOpacity onPress={this._onPressButton}>
+      <Image
+        style={styles.button}

    Troubleshooting
    These are some common issues you may run into while setting up React Native. If you encounter something that is not listed here, try searching for the issue in GitHub.
    
+
    Port already in use
    
+
    The React Native packager runs on port 8081. If another process is already using that port, you can either terminate that process, or change the port that the packager uses.
    
+
    Terminating a process on port 8081
    
+
    Run the following command to find the id for the process that is listening on port 8081:
    
+
    $ sudo lsof -i :8081
+
    
+
    Then run the following to terminate the process:
    
+
    $ kill -9 <PID>
+
    
+
    On Windows you can find the process using port 8081 using Resource Monitor and stop it using Task Manager.
    
+
    Using a port other than 8081
    
+
    You can configure the packager to use a port other than 8081 by using the port parameter:
    
+
    $ react-native start --port=8088
+
    
+
    You will also need to update your applications to load the JavaScript bundle from the new port. If running on device from Xcode, you can do this by updating occurrences of 8081 to your chosen port in the node_modules/react-native/React/React.xcodeproj/project.pbxproj file.
    
+
    NPM locking error
    
+
    If you encounter an error such as npm WARN locking Error: EACCES while using the React Native CLI, try running the following:
    
+
    sudo chown -R $USER ~/.npm
+sudo chown -R $USER /usr/local/lib/node_modules
+
    
+
    Missing libraries for React
    
+
    If you added React Native manually to your project, make sure you have included all the relevant dependencies that you are using, like RCTText.xcodeproj, RCTImage.xcodeproj. Next, the binaries built by these dependencies have to be linked to your app binary. Use the Linked Frameworks and Binaries section in the Xcode project settings. More detailed steps are here: Linking Libraries.
    
+
    If you are using CocoaPods, verify that you have added React along with the subspecs to the Podfile. For example, if you were using the <Text />, <Image /> and fetch() APIs, you would need to add these in your Podfile:
    
+
    pod 'React', :path => '../node_modules/react-native', :subspecs => [
+  'RCTText',
+  'RCTImage',
+  'RCTNetwork',
+  'RCTWebSocket',
+]
+
    
+
    Next, make sure you have run pod install and that a Pods/ directory has been created in your project with React installed. CocoaPods will instruct you to use the generated .xcworkspace file henceforth to be able to use these installed dependencies.
    
+
    React Native does not compile when being used as a CocoaPod
    
+
    There is a CocoaPods plugin called cocoapods-fix-react-native which handles any potential post-fixing of the source code due to differences when using a dependency manager.
    
+
    Argument list too long: recursive header expansion failed
    
+
    In the project's build settings, User Search Header Paths and Header Search Paths are two configs that specify where Xcode should look for #import header files specified in the code. For Pods, CocoaPods uses a default array of specific folders to look in. Verify that this particular config is not overwritten, and that none of the folders configured are too large. If one of the folders is a large folder, Xcode will attempt to recursively search the entire directory and throw above error at some point.
    
+
    To revert the User Search Header Paths and Header Search Paths build settings to their defaults set by CocoaPods - select the entry in the Build Settings panel, and hit delete. It will remove the custom override and return to the CocoaPod defaults.
    
+
    No transports available
    
+
    React Native implements a polyfill for WebSockets. These polyfills are initialized as part of the react-native module that you include in your application through import React from 'react'. If you load another module that requires WebSockets, such as Firebase, be sure to load/require it after react-native:
    
+
    import React from 'react';
+import Firebase from 'firebase';
+
    
+
    Shell Command Unresponsive Exception
    
+
    If you encounter a ShellCommandUnresponsiveException exception such as:
    
+
    Execution failed for task ':app:installDebug'.
+  com.android.builder.testing.api.DeviceException: com.android.ddmlib.ShellCommandUnresponsiveException
+
    
+
    Try downgrading your Gradle version to 1.2.3 in android/build.gradle.
    
+
    react-native init hangs
    
+
    If you run into issues where running react-native init hangs in your system, try running it again in verbose mode and refering to #2797 for common causes:
    
+
    react-native init --verbose
+
    
+
    Unable to start react-native package manager (on Linux)
    
+
    Case 1: Error "code":"ENOSPC","errno":"ENOSPC"
    
+
    Issue caused by the number of directories inotify (used by watchman on Linux) can monitor. To solve it, just run this command in your terminal window
    
+
    echo fs.inotify.max_user_watches=582222 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

    Learn the Basics
    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.
    
+
    Let's do this thing.
    
+
    Hello World
    
+
    In accordance with the ancient traditions of our people, we must first build an app that does nothing except say "Hello, world!". Here it is:
    
+
    import React, { Component } from 'react';
+import { Text, View } from 'react-native';
+
+export default class HelloWorldApp extends Component {
+  render() {
+    return (
+      <View style={{ flex: 1, justifyContent: "center", alignItems: "center" }}>
+        <Text>Hello, world!</Text>
+      </View>
+    );
+  }
+}
+
    
+
+
    If you are feeling curious, you can play around with sample code directly in the web simulators. You can also paste it into your App.js file to create a real app on your local machine.
    
+
    What's going on here?
    
+
    Some of the things in here might not look like JavaScript to you. Don't panic. This is the future.
    
+
    First of all, ES2015 (also known as ES6) is a set of improvements to JavaScript that is now part of the official standard, but not yet supported by all browsers, so often it isn't used yet in web development. React Native ships with ES2015 support, so you can use this stuff without worrying about compatibility. import, from, class, and extends in the example above are all ES2015 features. If you aren't familiar with ES2015, you can probably pick it up just by reading through sample code like this tutorial has. If you want, this page has a good overview of ES2015 features.
    
+
    The other unusual thing in this code example is <View><Text>Hello world!</Text></View>. This is JSX - a syntax for embedding XML within JavaScript. Many frameworks use a special templating language which lets you embed code inside markup language. In React, this is reversed. JSX lets you write your markup language inside code. It looks like HTML on the web, except instead of web things like <div> or <span>, you use React components. In this case, <Text> is a built-in component that just displays some text and View is like the <div> or <span>.
    
+
    Components
    
+
    So this code is defining HelloWorldApp, a new Component. When you're building a React Native app, you'll be making new components a lot. Anything you see on the screen is some sort of component. A component can be pretty simple - the only thing that's required is a render function which returns some JSX to render.
    
+
    This app doesn't do very much
    
+
    Good point. To make components do more interesting things, you need to learn about Props.

+Understanding the CLI · React Native
    0.58
    Edit
    Understanding the CLI
    Though you may have installed the react-native-cli via npm as a separate module, it is a shell for accessing the CLI embedded in the React Native of each project. Your commands and their effects are dependent on the version of the module of react-native in context of the project. This guide will give a brief overview of the CLI in the module.
    
+
    The local CLI
    
+
    React Native has a local-cli folder with a file named cli.js. Here, the commands are read from commands.js and added as possible CLI commands. E.G. the react-native link command, exists in the react-native/local-cli/link folder, and is required in commands.js, which will register it as a documented command to be exposed to the CLI.
    
+
    Command definitions
    
+
    At the end of each command entry is an export. The export is an object with a function to perform, description of the command, and the command name. The object structure for the link command looks like so:
    
+
    module.exports = {
+  func: link,
+  description: 'links all native dependencies',
+  name: 'link [packageName]',
+};
+
    
+
    Parameters
    
+
    The command name identifies the parameters that a command would expect. When the command parameter is surrounded by greater-than, less-than symbols < >, this indicates that the parameter is expected. When a parameter is surrounded by brackets [ ], this indicates that the parameter is optional.
    
+
    Getting a list of all CLI commands
    
+
    Running react-native --help from inside a React Native project will list all of your current commands. Here is an example from version 0.56:
    
+
      Usage: react-native [options] [command]
+
+  Options:
+
+    -V, --version                      output the version number
+    -h, --help                         output usage information
+
+  Commands:
+
+    start [options]                    starts the webserver
+    run-ios [options]                  builds your app and starts it on iOS simulator
+    run-android [options]              builds your app and starts it on a connected Android emulator or device
+    new-library [options]              generates a native library bridge
+    bundle [options]                   builds the javascript bundle for offline use
+    unbundle [options]                 builds javascript as "unbundle" for offline use
+    eject [options]                    Re-create the iOS and Android folders and native code
+    link [options] [packageName]       links all native dependencies (updates native build files)
+    unlink [options] <packageName>     unlink native dependency
+    install [options] <packageName>    install and link native dependencies
+    uninstall [options] <packageName>  uninstall and unlink native dependencies
+    upgrade [options]                  upgrade your app's template files to the latest version; run this after updating the react-native version in your package.json and running npm install
+    log-android [options]              starts adb logcat
+    log-ios [options]                  starts iOS device syslog tail
+    dependencies [options]             lists dependencies
+    info [options]                     Get relevant version info about OS, toolchain and libraries
+
    
+
    CLI Configs
    
+
    When using react-native start, its platform derivatives, and react-native bundle you can use a file to define the CLI options used by React Native by default. If you create a file rn-cli.config.js in the root of your project, it will be evaluated and options for the commands will come from there.
    
+
    You can see the options for the CLI config on the metro website. Here's a common rn-cli.config.js used for supporting TypeScript in React Native projects:
    
+
    module.exports = {
+  getTransformModulePath() {
+    return require.resolve('react-native-typescript-transformer');
+  },
+  getSourceExts() {
+    return ['ts', 'tsx'];
+  },
+};

    Upgrading to new React Native versions
    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you.
    
+
    Expo projects
    
+
    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.
    
+
    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.
    
+
    React Native projects
    
+
    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.
    
+
    Upgrade based on Git
    
+
    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.
    
+
    1. Make sure your project uses Git
    
+
    
+
    This step applies only to projects that don't use Git. Skip it if yours use it.
    
+
    
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
+
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
+
    Run the following command to start the process of upgrading to the latest version:
    
+
    react-native upgrade
+
    
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
+
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
+
    4. Resolve the conflicts
    
+
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
+
    13B07F951A680F5B00A75B9A /* Release */ = {
+  isa = XCBuildConfiguration;
+  buildSettings = {
+    ASSETCATALOG_COMPILER_APPICON_NAME = AppIcon;
+<<<<<<< ours
+    CODE_SIGN_IDENTITY = "iPhone Developer";
+    FRAMEWORK_SEARCH_PATHS = (
+      "$(inherited)",
+      "$(PROJECT_DIR)/HockeySDK.embeddedframework",
+      "$(PROJECT_DIR)/HockeySDK-iOS/HockeySDK.embeddedframework",
+    );
+=======
+    CURRENT_PROJECT_VERSION = 1;
+>>>>>>> theirs
+    HEADER_SEARCH_PATHS = (
+      "$(inherited)",
+      /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include,
+      "$(SRCROOT)/../node_modules/react-native/React/**",
+      "$(SRCROOT)/../node_modules/react-native-code-push/ios/CodePush/**",
+    );
+
    
+
    You can think of "ours" as "your team" and "theirs" as "the React Native dev team".
    
+
    Alternative
    
+
    Use this only in case the above didn't work.
    
+
    1. Upgrade the react-native dependency
    
+
    Note the latest version of the react-native npm package from here (or use npm info react-native to check).
    
+
    Now install that version of react-native in your project with npm install --save:
    
+
    $ npm install --save react-native@X.Y
+# where X.Y is the semantic version you are upgrading to
+npm WARN peerDependencies The peer dependency react@~R included from react-native...
+
    
+
    If you saw a warning about the peerDependency, also upgrade react by running:
    
+
    $ npm install --save react@R
+# where R is the new version of react from the peerDependency warning you saw
+
    
+
    2. Upgrade your project templates
    
+
    The new npm package may contain updates to the files that are normally generated when you run react-native init, like the iOS and the Android sub-projects.
    
+
    You may consult rn-diff-purge to see if there were changes in the project template files. In case there weren't any, simply rebuild the project and continue developing. In case of minor changes, you may update your project manually and rebuild.
    
+
    If there were major changes, run this in a terminal to get these:
    
+
    $ react-native upgrade
+
    
+
    This will check your files against the latest template and perform the following:
    
+
      
+
    • If there is a new file in the template, it is simply created.
      • 
+
    • If a file in the template is identical to your file, it is skipped.
      • 
+
    • If a file is different in your project than the template, you will be prompted; you have options to keep your file or overwrite it with the template version.
      • 
+
    
+
    Manual Upgrades
    
+
    Some upgrades require manual steps, e.g. 0.28 to 0.29, or 0.56 to 0.57. Be sure to check the release notes when upgrading so that you can identify any manual changes your particular project may require.

+Using List Views · React Native
    0.58
    Edit
    Using List Views
    React Native provides a suite of components for presenting lists of data. Generally, you'll want to use either FlatList or SectionList.
    
+
    The FlatList component displays a scrolling list of changing, but similarly structured, data. FlatList works well for long lists of data, where the number of items might change over time. Unlike the more generic ScrollView, the FlatList only renders elements that are currently showing on the screen, not all the elements at once.
    
+
    The FlatList component requires two props: data and renderItem. data is the source of information for the list. renderItem takes one item from the source and returns a formatted component to render.
    
+
    This example creates a simple FlatList of hardcoded data. Each item in the data props is rendered as a Text component. The FlatListBasics component then renders the FlatList and all Text components.
    
+
    If you want to render a set of data broken into logical sections, maybe with section headers, similar to UITableViews on iOS, then a SectionList is the way to go.
    
+
    One of the most common uses for a list view is displaying data that you fetch from a server. To do that, you will need to learn about networking in React Native.

    Using a ScrollView
    The ScrollView is a generic scrolling container that can host multiple components and views. The scrollable items need not be homogeneous, and you can scroll both vertically and horizontally (by setting the horizontal property).
    
+
    This example creates a vertical ScrollView with both images and text mixed together.
    
+
    import React, { Component } from 'react';
+import { AppRegistry, ScrollView, Image, Text } from 'react-native';
+
+export default class IScrolledDownAndWhatHappenedNextShockedMe extends Component {
+  render() {
+      return (
+        <ScrollView>
+          <Text style={{fontSize:96}}>Scroll me plz</Text>

+
    ScrollViews can be configured to allow paging through views using swiping gestures by using the pagingEnabled props. Swiping horizontally between views can also be implemented on Android using the ViewPagerAndroid component.
    
+
    A ScrollView with a single item can be used to allow the user to zoom content. Set up the maximumZoomScale and minimumZoomScale props and your user will be able to use pinch and expand gestures to zoom in and out.
    
+
    The ScrollView works best to present a small amount of things of a limited size. All the elements and views of a ScrollView are rendered, even if they are not currently shown on the screen. If you have a long list of more items than can fit on the screen, you should use a FlatList instead. So let's learn about list views next.

+Vibration · React Native
    0.58
    Edit
    Vibration
    The Vibration API is exposed at Vibration.vibrate(). The vibration is asynchronous so this method will return immediately.
    
+
    There will be no effect on devices that do not support Vibration, eg. the simulator.
    
+
    Note for Android: add <uses-permission android:name="android.permission.VIBRATE"/> to AndroidManifest.xml
    
+
    The vibration duration in iOS is not configurable, so there are some differences with Android. In Android, if pattern is a number, it specifies the vibration duration in ms. If pattern is an array, those odd indices are the vibration duration, while the even ones are the separation time.
    
+
    In iOS, invoking vibrate(duration) will just ignore the duration and vibrate for a fixed time. While the pattern array is used to define the duration between each vibration. See below example for more.
    
+
    Repeatable vibration is also supported, the vibration will repeat with defined pattern until cancel() is called.
    
+
    Example:
    
+
    const DURATION = 10000;
+const PATTERN = [1000, 2000, 3000];
+
+Vibration.vibrate(DURATION);
+// Android: vibrate for 10s
+// iOS: duration is not configurable, vibrate for fixed time (about 500ms)
+
+Vibration.vibrate(PATTERN);
+// Android: wait 1s -> vibrate 2s -> wait 3s
+// iOS: wait 1s -> vibrate -> wait 2s -> vibrate -> wait 3s -> vibrate
+
+Vibration.vibrate(PATTERN, true);
+// Android: wait 1s -> vibrate 2s -> wait 3s -> wait 1s -> vibrate 2s -> wait 3s -> ...

+View · React Native
    0.58
    Edit
    View
    The most fundamental component for building a UI, View is a container that supports layout with flexbox, style, some touch handling, and accessibility controls. View maps directly to the native view equivalent on whatever platform React Native is running on, whether that is a UIView, <div>, android.view, etc.
    
+
    View is designed to be nested inside other views and can have 0 to many children of any type.
    
+
    This example creates a View that wraps two colored boxes and a text component in a row with padding.
    
+
    class ViewColoredBoxesWithText extends Component {
+  render() {
+    return (
+      <View
+        style={{
+          flexDirection: 'row',
+          height: 100,
+          padding: 20,
+        }}>
+        <View style={{backgroundColor: 'blue', flex: 0.3}} />
+        <View style={{backgroundColor: 'red', flex: 0.5}} />
+        <Text>Hello World!</Text>
+      </View>
+    );
+  }
+}
+
    
+
    
+
    Views are designed to be used with StyleSheet for clarity and performance, although inline styles are also supported.
    
+
    
+
    Synthetic Touch Events
    
+
    For View responder props (e.g., onResponderMove), the synthetic touch event passed to them are of the following form:
    
+
      
+
    • nativeEvent
+
        
+
      • changedTouches - Array of all touch events that have changed since the last event.
        • 
+
      • identifier - The ID of the touch.
        • 
+
      • locationX - The X position of the touch, relative to the element.
        • 
+
      • locationY - The Y position of the touch, relative to the element.
        • 
+
      • pageX - The X position of the touch, relative to the root element.
        • 
+
      • pageY - The Y position of the touch, relative to the root element.
        • 
+
      • target - The node id of the element receiving the touch event.
        • 
+
      • timestamp - A time identifier for the touch, useful for velocity calculation.
        • 
+
      • touches - Array of all current touches on the screen.
        • 
+
      • 
+
    
+
    Props
    
+
+
    
+
    Reference
    
+
    Props
    
+
    onStartShouldSetResponder
    
+
    Does this view want to become responder on the start of a touch?
    
+
    View.props.onStartShouldSetResponder: (event) => [true | false], where event is a synthetic touch event as described above.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    accessibilityHint
    
+
    An accessibility hint helps users understand what will happen when they perform an action on the accessibility element when that result is not obvious from the accessibility label.
    
+
+
+
+
+
+
+
+
    TypeRequired
    stringNo
    
+
    
+
    accessibilityLabel
    
+
    Overrides the text that's read by the screen reader when the user interacts with the element. By default, the label is constructed by traversing all the children and accumulating all the Text nodes separated by space.
    
+
+
+
+
+
+
+
+
    TypeRequired
    nodeNo
    
+
    
+
    hitSlop
    
+
    This defines how far a touch event can start away from the view. Typical interface guidelines recommend touch targets that are at least 30 - 40 points/density-independent pixels.
    
+
    For example, if a touchable view has a height of 20 the touchable height can be extended to 40 with hitSlop={{top: 10, bottom: 10, left: 0, right: 0}}
    
+
    
+
    The touch area never extends past the parent view bounds and the Z-index of sibling views always takes precedence if a touch hits two overlapping views.
    
+
    
+
+
+
+
+
+
+
+
    TypeRequired
    object: {top: number, left: number, bottom: number, right: number}No
    
+
    
+
    nativeID
    
+
    Used to locate this view from native classes.
    
+
    
+
    This disables the 'layout-only view removal' optimization for this view!
    
+
    
+
+
+
+
+
+
+
+
    TypeRequired
    stringNo
    
+
    
+
    onAccessibilityTap
    
+
    When accessible is true, the system will try to invoke this function when the user performs accessibility tap gesture.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onLayout
    
+
    Invoked on mount and layout changes with:
    
+
    {nativeEvent: { layout: {x, y, width, height}}}
    
+
    This event is fired immediately once the layout has been calculated, but the new layout may not yet be reflected on the screen at the time the event is received, especially if a layout animation is in progress.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onMagicTap
    
+
    When accessible is true, the system will invoke this function when the user performs the magic tap gesture.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onMoveShouldSetResponder
    
+
    Does this view want to "claim" touch responsiveness? This is called for every touch move on the View when it is not the responder.
    
+
    View.props.onMoveShouldSetResponder: (event) => [true | false], where event is a synthetic touch event as described above.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onMoveShouldSetResponderCapture
    
+
    If a parent View wants to prevent a child View from becoming responder on a move, it should have this handler which returns true.
    
+
    View.props.onMoveShouldSetResponderCapture: (event) => [true | false], where event is a synthetic touch event as described above.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onResponderGrant
    
+
    The View is now responding for touch events. This is the time to highlight and show the user what is happening.
    
+
    View.props.onResponderGrant: (event) => {}, where event is a synthetic touch event as described above.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+

+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onResponderReject
    
+
    Another responder is already active and will not release it to that View asking to be the responder.
    
+
    View.props.onResponderReject: (event) => {}, where event is a synthetic touch event as described above.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onResponderRelease
    
+
    Fired at the end of the touch.
    
+
    View.props.onResponderRelease: (event) => {}, where event is a synthetic touch event as described above.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onResponderTerminate
    
+
    The responder has been taken from the View. Might be taken by other views after a call to onResponderTerminationRequest, or might be taken by the OS without asking (e.g., happens with control center/ notification center on iOS)
    
+
    View.props.onResponderTerminate: (event) => {}, where event is a synthetic touch event as described above.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onResponderTerminationRequest
    
+
    Some other View wants to become responder and is asking this View to release its responder. Returning true allows its release.
    
+
    View.props.onResponderTerminationRequest: (event) => {}, where event is a synthetic touch event as described above.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    accessible
    
+
    When true, indicates that the view is an accessibility element. By default, all the touchable elements are accessible.
    
+
+
+
+
+
+
+
+
    TypeRequired
    boolNo
    
+
    
+
    onStartShouldSetResponderCapture
    
+
    If a parent View wants to prevent a child View from becoming responder on a touch start, it should have this handler which returns true.
    
+
    View.props.onStartShouldSetResponderCapture: (event) => [true | false], where event is a synthetic touch event as described above.
    
+
+
+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    pointerEvents
    
+
    Controls whether the View can be the target of touch events.
    
+
      
+
    • 'auto': The View can be the target of touch events.
      • 
+
    • 'none': The View is never the target of touch events.
      • 
+
    • 'box-none': The View is never the target of touch events but it's subviews can be. It behaves like if the view had the following classes in CSS:
      • 
+
    
+
    .box-none {
+     pointer-events: none;
+}
+.box-none * {
+     pointer-events: all;
+}
+
    
+
      
+
    • 'box-only': The view can be the target of touch events but it's subviews cannot be. It behaves like if the view had the following classes in CSS:
      • 
+
    
+
    .box-only {
+     pointer-events: all;
+}
+.box-only * {
+     pointer-events: none;
+}
+
    
+
    
+
    Since pointerEvents does not affect layout/appearance, and we are already deviating from the spec by adding additional modes, we opt to not include pointerEvents on style. On some platforms, we would need to implement it as a className anyways. Using style or not is an implementation detail of the platform.
    
+
    
+
+
+
+
+
+
+
+
    TypeRequired
    enum('box-none', 'none', 'box-only', 'auto')No
    
+
    
+
    removeClippedSubviews
    
+
    This is a special performance property exposed by RCTView and is useful for scrolling content when there are many subviews, most of which are offscreen. For this property to be effective, it must be applied to a view that contains many subviews that extend outside its bound. The subviews must also have overflow: hidden, as should the containing view (or one of its superviews).

    Indicates to accessibility services whether the user should be notified when this view changes. Works for Android API >= 19 only. Possible values:
    
+
      
+
    • 'none' - Accessibility services should not announce changes to this view.
      • 
+
    • 'polite'- Accessibility services should announce changes to this view.
      •

    importantForAccessibility
    
+
    Controls how view is important for accessibility which is if it fires accessibility events and if it is reported to accessibility services that query the screen. Works for Android only.
    
+
    Possible values:
    
+
      
+
    • 'auto' - The system determines whether the view is important for accessibility - default (recommended).
      • 
+
    • 'yes' - The view is important for accessibility.
      • 
+
    • 'no' - The view is not important for accessibility.
      • 
+
    • 'no-hide-descendants' - The view is not important for accessibility, nor are any of its descendant views.

    needsOffscreenAlphaCompositing
    
+
    Whether this View needs to rendered offscreen and composited with an alpha in order to preserve 100% correct colors and blending behavior. The default (false) falls back to drawing the component and its children with an alpha applied to the paint used to draw each element instead of rendering the full component offscreen and compositing it back with an alpha value. This default may be noticeable and undesired in the case where the View you are setting an opacity on has multiple overlapping elements (e.g. multiple overlapping Views, or text and a background).
    
+
    Rendering offscreen to preserve correct alpha behavior is extremely expensive and hard to debug for non-native developers, which is why it is not turned on by default. If you do need to enable this property for an animation, consider combining it with renderToHardwareTextureAndroid if the view contents are static (i.e. it doesn't need to be redrawn each frame). If that property is enabled, this View will be rendered off-screen once, saved in a hardware texture, and then composited onto the screen with an alpha each frame without having to switch rendering targets on the GPU.

    renderToHardwareTextureAndroid
    
+
    Whether this View should render itself (and all of its children) into a single hardware texture on the GPU.
    
+
    On Android, this is useful for animations and interactions that only modify opacity, rotation, translation, and/or scale: in those cases, the view doesn't have to be redrawn and display lists don't need to be re-executed. The texture can just be re-used and re-composited with different parameters. The downside is that this can use up limited video memory, so this prop should be set back to false at the end of the interaction/animation.

    accessibilityRole
    
+
    > Note: AccessibilityRole and AccessibilityStates are meant to be a cross-platform solution to replace accessibilityTraits and accessibilityComponentType, which will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    Tells the screen reader to treat the currently focused on element as having a specific role.
    
+
    Possible values for AccessibilityRole is one of:
    
+
      
+
    • 'none' - The element has no role.
      • 
+
    • 'button' - The element should be treated as a button.
      • 
+
    • 'link' - The element should be treated as a link.
      • 
+
    • 'header' - The element is a header that divides content into sections.
      • 
+
    • 'search' - The element should be treated as a search field.
      • 
+
    • 'image' - The element should be treated as an image.
      • 
+
    • 'key' - The element should be treated like a keyboard key.
      • 
+
    • 'text' - The element should be treated as text.
      • 
+
    • 'summary' - The element provides app summary information.
      •

    • 'imagebutton' - The element has the role of both an image and also a button.
      • 
+
    • 'adjustable' - The element allows adjustment over a range of values.
      • 
+
    
+
    On iOS, these roles map to corresponding Accessibility Traits. Image button has the same functionality as if the trait was set to both 'image' and 'button'. See the Accessibility guide for more information.
    
+
    On Android, these roles have similar functionality on TalkBack as adding Accessibility Traits does on Voiceover in iOS

    On iOS, this is useful for animations and interactions that do not modify this component's dimensions nor its children; for example, when translating the position of a static view, rasterization allows the renderer to reuse a cached bitmap of a static view and quickly composite it during each frame.

    Rasterization incurs an off-screen drawing pass and the bitmap consumes memory. Test and measure when using this property.

    0.58
    Edit
    View
    The most fundamental component for building a UI, View is a container that supports layout with flexbox, style, some touch handling, and accessibility controls. View maps directly to the native view equivalent on whatever platform React Native is running on, whether that is a UIView, <div>, android.view, etc.
    
+
    View is designed to be nested inside other views and can have 0 to many children of any type.
    
+
    This example creates a View that wraps two colored boxes and a text component in a row with padding.
    
+
    class ViewColoredBoxesWithText extends Component {
+  render() {
+    return (
+      <View
+        style={{
+          flexDirection: 'row',
+          height: 100,
+          padding: 20,
+        }}>
+        <View style={{backgroundColor: 'blue', flex: 0.3}} />
+        <View style={{backgroundColor: 'red', flex: 0.5}} />
+        <Text>Hello World!</Text>
+      </View>
+    );
+  }
+}
+
    
+
    
+
    Views are designed to be used with StyleSheet for clarity and performance, although inline styles are also supported.
    
+
    
+
    Synthetic Touch Events
    
+
    For View responder props (e.g., onResponderMove), the synthetic touch event passed to them are of the following form:
    
+
      
+
    • nativeEvent
+
        
+
      • changedTouches - Array of all touch events that have changed since the last event.
        • 
+
      • identifier - The ID of the touch.
        • 
+
      • locationX - The X position of the touch, relative to the element.
        • 
+
      • locationY - The Y position of the touch, relative to the element.
        • 
+
      • pageX - The X position of the touch, relative to the root element.
        • 
+
      • pageY - The Y position of the touch, relative to the root element.
        • 
+
      • target - The node id of the element receiving the touch event.
        • 
+
      • timestamp - A time identifier for the touch, useful for velocity calculation.
        • 
+
      • touches - Array of all current touches on the screen.

    onStartShouldSetResponder
    
+
    Does this view want to become responder on the start of a touch?
    
+
    View.props.onStartShouldSetResponder: (event) => [true | false], where event is a synthetic touch event as described above.

    accessibilityHint
    
+
    An accessibility hint helps users understand what will happen when they perform an action on the accessibility element when that result is not obvious from the accessibility label.
    
+
+
+
+
+
+
+
+
    TypeRequired
    stringNo
    
+
    
+
    accessibilityLabel
    
+
    Overrides the text that's read by the screen reader when the user interacts with the element. By default, the label is constructed by traversing all the children and accumulating all the Text nodes separated by space.
    
+
+
+
+
+
+
+
+
    TypeRequired
    nodeNo
    
+
    
+
    hitSlop
    
+
    This defines how far a touch event can start away from the view. Typical interface guidelines recommend touch targets that are at least 30 - 40 points/density-independent pixels.
    
+
    For example, if a touchable view has a height of 20 the touchable height can be extended to 40 with hitSlop={{top: 10, bottom: 10, left: 0, right: 0}}
    
+
    
+
    The touch area never extends past the parent view bounds and the Z-index of sibling views always takes precedence if a touch hits two overlapping views.

    Controls whether the View can be the target of touch events.

+
    • 'auto': The View can be the target of touch events.
      • 
+
    • 'none': The View is never the target of touch events.
      • 
+
    • 'box-none': The View is never the target of touch events but it's subviews can be. It behaves like if the view had the following classes in CSS:
      • 
+
    
+
    .box-none {
+     pointer-events: none;
+}
+.box-none * {
+     pointer-events: all;

    • 'box-only': The view can be the target of touch events but it's subviews cannot be. It behaves like if the view had the following classes in CSS:
      • 
+
    
+
    .box-only {
+     pointer-events: all;
+}
+.box-only * {
+     pointer-events: none;
+}
+
    
+
    
+
    Since pointerEvents does not affect layout/appearance, and we are already deviating from the spec by adding additional modes, we opt to not include pointerEvents on style. On some platforms, we would need to implement it as a className anyways. Using style or not is an implementation detail of the platform.

    This is a special performance property exposed by RCTView and is useful for scrolling content when there are many subviews, most of which are offscreen. For this property to be effective, it must be applied to a view that contains many subviews that extend outside its bound. The subviews must also have overflow: hidden, as should the containing view (or one of its superviews).

    needsOffscreenAlphaCompositing
    
+
    Whether this View needs to rendered offscreen and composited with an alpha in order to preserve 100% correct colors and blending behavior. The default (false) falls back to drawing the component and its children with an alpha applied to the paint used to draw each element instead of rendering the full component offscreen and compositing it back with an alpha value. This default may be noticeable and undesired in the case where the View you are setting an opacity on has multiple overlapping elements (e.g. multiple overlapping Views, or text and a background).
    
+
    Rendering offscreen to preserve correct alpha behavior is extremely expensive and hard to debug for non-native developers, which is why it is not turned on by default. If you do need to enable this property for an animation, consider combining it with renderToHardwareTextureAndroid if the view contents are static (i.e. it doesn't need to be redrawn each frame). If that property is enabled, this View will be rendered off-screen once, saved in a hardware texture, and then composited onto the screen with an alpha each frame without having to switch rendering targets on the GPU.

    renderToHardwareTextureAndroid
    
+
    Whether this View should render itself (and all of its children) into a single hardware texture on the GPU.
    
+
    On Android, this is useful for animations and interactions that only modify opacity, rotation, translation, and/or scale: in those cases, the view doesn't have to be redrawn and display lists don't need to be re-executed. The texture can just be re-used and re-composited with different parameters. The downside is that this can use up limited video memory, so this prop should be set back to false at the end of the interaction/animation.

    accessibilityRole
    
+
    > Note: AccessibilityRole and AccessibilityStates are meant to be a cross-platform solution to replace accessibilityTraits and accessibilityComponentType, which will soon be deprecated. When possible, use accessibilityRole and accessibilityStates instead of accessibilityTraits and accessibilityComponentType.
    
+
    Tells the screen reader to treat the currently focused on element as having a specific role.
    
+
    Possible values for AccessibilityRole is one of:
    
+
      
+
    • 'none' - The element has no role.
      • 
+
    • 'button' - The element should be treated as a button.
      • 
+
    • 'link' - The element should be treated as a link.
      • 
+
    • 'header' - The element is a header that divides content into sections.
      • 
+
    • 'search' - The element should be treated as a search field.
      • 
+
    • 'image' - The element should be treated as an image.
      • 
+
    • 'key' - The element should be treated like a keyboard key.
      • 
+
    • 'text' - The element should be treated as text.
      • 
+
    • 'summary' - The element provides app summary information.
      • 
+
    • 'imagebutton' - The element has the role of both an image and also a button.
      • 
+
    • 'adjustable' - The element allows adjustment over a range of values.
      • 
+
    
+
    On iOS, these roles map to corresponding Accessibility Traits. Image button has the same functionality as if the trait was set to both 'image' and 'button'. See the Accessibility guide for more information.
    
+
    On Android, these roles have similar functionality on TalkBack as adding Accessibility Traits does on Voiceover in iOS

    Tells the screen reader to treat the currently focused on element as being in a specific state.
    
+
    You can provide one state, no state, or both states. The states must be passed in through an array. Ex: ['selected'] or ['selected', 'disabled']
    
+
    Possible values for AccessibilityStates are:

    On iOS, this is useful for animations and interactions that do not modify this component's dimensions nor its children; for example, when translating the position of a static view, rasterization allows the renderer to reuse a cached bitmap of a static view and quickly composite it during each frame.
    
+
    Rasterization incurs an off-screen drawing pass and the bitmap consumes memory. Test and measure when using this property.

    VirtualizedList
    Base implementation for the more convenient <FlatList> and <SectionList> components, which are also better documented. In general, this should only really be used if you need more flexibility than FlatList provides, e.g. for use with immutable data instead of plain arrays.
    
+
    Virtualization massively improves memory consumption and performance of large lists by maintaining a finite render window of active items and replacing all items outside of the render window with appropriately sized blank space. The window adapts to scrolling behavior, and items are rendered incrementally with low-pri (after any running interactions) if they are far from the visible area, or with hi-pri otherwise to minimize the potential of seeing blank space.
    
+
    Some caveats:
    
+
      
+
    • Internal state is not preserved when content scrolls out of the render window. Make sure all your data is captured in the item data or external stores like Flux, Redux, or Relay.
      • 
+
    • This is a PureComponent which means that it will not re-render if props remain shallow- equal. Make sure that everything your renderItem function depends on is passed as a prop (e.g. extraData) that is not === after updates, otherwise your UI may not update on changes. This includes the data prop and parent component state.
      • 
+
    • In order to constrain memory and enable smooth scrolling, content is rendered asynchronously offscreen. This means it's possible to scroll faster than the fill rate and momentarily see blank content. This is a tradeoff that can be adjusted to suit the needs of each application, and we are working on improving it behind the scenes.

    • By default, the list looks for a key prop on each item and uses that for the React key. Alternatively, you can provide a custom keyExtractor prop.

+
    TypeRequired
    booleanNo
    
+
    
+
    extraData
    
+
    A marker property for telling the list to re-render (since it implements PureComponent). If any of your renderItem, Header, Footer, etc. functions depend on anything outside of the data prop, stick it here and treat it immutably.

    (item: object, index: number) => string;
+
    
+
    Used to extract a unique key for a given item at the specified index. Key is used for caching and as the react key to track item re-ordering. The default extractor checks item.key, then falls back to using the index, like React does.

    TypeRequired
    functionNo
    
+
    
+
    maxToRenderPerBatch

    The maximum number of items to render in each incremental render batch. The more rendered at once, the better the fill rate, but responsiveness may suffer because rendering content may interfere with responding to button taps or other interactions.
    
+

+
+
+
+
+
+
    TypeRequired
    functionNo
    
+
    
+
    onEndReachedThreshold
    
+
    How far from the end (in units of visible length of the list) the bottom edge of the list must be from the end of the content to trigger the onEndReached callback. Thus a value of 0.5 will trigger onEndReached when the end of the content is within half the visible length of the list.

    TypeRequired
    numberNo
    
+
    
+
    windowSize
    
+
    Determines the maximum number of items rendered outside of the visible area, in units of visible lengths. So if your list fills the screen, then windowSize={21} (the default) will render the visible screen area plus up to 10 screens above and 10 below the viewport. Reducing this number will reduce memory consumption and may improve performance, but will increase the chance that fast scrolling may reveal momentary blank areas of unrendered content.

    Edit
    VirtualizedList
    Base implementation for the more convenient <FlatList> and <SectionList> components, which are also better documented. In general, this should only really be used if you need more flexibility than FlatList provides, e.g. for use with immutable data instead of plain arrays.
    
+
    Virtualization massively improves memory consumption and performance of large lists by maintaining a finite render window of active items and replacing all items outside of the render window with appropriately sized blank space. The window adapts to scrolling behavior, and items are rendered incrementally with low-pri (after any running interactions) if they are far from the visible area, or with hi-pri otherwise to minimize the potential of seeing blank space.
    
+
    Some caveats:
    
+
      
+
    • Internal state is not preserved when content scrolls out of the render window. Make sure all your data is captured in the item data or external stores like Flux, Redux, or Relay.
      • 
+
    • This is a PureComponent which means that it will not re-render if props remain shallow- equal. Make sure that everything your renderItem function depends on is passed as a prop (e.g. extraData) that is not === after updates, otherwise your UI may not update on changes. This includes the data prop and parent component state.
      • 
+
    • In order to constrain memory and enable smooth scrolling, content is rendered asynchronously offscreen. This means it's possible to scroll faster than the fill rate and momentarily see blank content. This is a tradeoff that can be adjusted to suit the needs of each application, and we are working on improving it behind the scenes.
      • 
+
    • By default, the list looks for a key prop on each item and uses that for the React key. Alternatively, you can provide a custom keyExtractor prop.

    onEndReachedThreshold
    
+
    How far from the end (in units of visible length of the list) the bottom edge of the list must be from the end of the content to trigger the onEndReached callback. Thus a value of 0.5 will trigger onEndReached when the end of the content is within half the visible length of the list.

    Amount of time between low-pri item render batches, e.g. for rendering items quite a ways off screen. Similar fill rate/responsiveness tradeoff as maxToRenderPerBatch.

+
    windowSize
    
+
    Determines the maximum number of items rendered outside of the visible area, in units of visible lengths. So if your list fills the screen, then windowSize={21} (the default) will render the visible screen area plus up to 10 screens above and 10 below the viewport. Reducing this number will reduce memory consumption and may improve performance, but will increase the chance that fast scrolling may reveal momentary blank areas of unrendered content.

    WebView
    
+
    Warning Please use the react-native-community/react-native-webview fork of this component instead. To reduce the surface area of React Native, <WebView/> is going to be removed from the React Native core. For more information, please read The Slimmening proposal.
    
+
    
+
    WebView renders web content in a native view.
    
+
    import React, {Component} from 'react';
+import {WebView} from 'react-native';
+
+class MyWeb extends Component {
+  render() {
+    return (
+      <WebView
+        source={{uri: 'https://github.com/facebook/react-native'}}
+        style={{marginTop: 20}}
+      />
+    );
+  }
+}
+
    
+
    Minimal example with inline HTML:
    
+
    import React, {Component} from 'react';
+import {WebView} from 'react-native';
+
+class MyInlineWeb extends Component {
+  render() {
+    return (
+      <WebView
+        originWhitelist={['*']}
+        source={{html: '<h1>Hello world</h1>'}}
+      />
+    );
+  }
+}
+
    
+
    You can use this component to navigate back and forth in the web view's history and configure various properties for the web content.
    
+
    On iOS, the useWebKit prop can be used to opt into a WKWebView-backed implementation.
    
+
    
+
    Security Warning: Currently, onMessage and postMessage do not allow specifying an origin. This can lead to cross-site scripting attacks if an unexpected document is loaded within a WebView instance. Please refer to the MDN documentation for Window.postMessage() for more details on the security implications of this.

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-
    
-
     if [ "${CONFIGURATION}" == "Debug" ]; then
-  export SKIP_BUNDLING=true

    Pro Tips
    
 
    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
   launchScreenView.frame = self.window.bounds;

    3. Build app for release
    
 
    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.
    
 
    
 
    You can also use the React Native CLI to perform this operation using the option --configuration with the value Release (e.g. react-native run-ios --configuration Release).

    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];
   launchScreenView.frame = self.window.bounds;
   rootView.loadingView = launchScreenView;

    3. Build app for release
    
 
    You can now build your app for release by tapping ⌘B or selecting Product → Build from the menu bar. Once built for release, you'll be able to distribute the app to beta testers and submit the app to the App Store.
    
 
    
 
    You can also use the React Native CLI to perform this operation using the option --configuration with the value Release (e.g. react-native run-ios --configuration Release).

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests.

    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    Upgrading to new React Native versions

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you. The instructions are a bit different depending on whether you used create-react-native-app or react-native init to create your project.

    Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Upgrading requires a small amount of effort, but we try to make it easy for you.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    See the Upgrading Expo SDK Walkthrough for up-to-date information about upgrading your project.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Screenshot/Snapshot Tests
    
 
    A common type of integration test is the snapshot test. These tests render a component, and verify snapshots of the screen against reference images using TestModule.verifySnapshot(), using the FBSnapshotTestCase library behind the scenes. Reference images are recorded by setting recordMode = YES on the RCTTestRunner, then running the tests. Snapshots will differ slightly between 32 and 64 bit, and various OS versions, so it's recommended that you enforce tests are run with the correct configuration. It's also highly recommended that all network data be mocked out, along with other potentially troublesome dependencies. See SimpleSnapshotTest for a basic example.
    
 
    If you make a change that affects a snapshot test in a PR, such as adding a new example case to one of the examples that is snapshotted, you'll need to re-record the snapshot reference image. To do this, simply change to _runner.recordMode = YES; in RNTester/RNTesterSnapshotTests.m, re-run the failing tests, then flip record back to NO and submit/update your PR and wait to see if the Circle build passes.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    Expo projects

    Upgrading your Expo project to a new version of React Native requires updating the react-native, react, and expo package versions in your package.json file. Please refer to this list to find out what versions are supported. You will also need to set the correct sdkVersion in your app.json file.

    React Native projects

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif
-
    
-
    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.
    
-
    
-
    Note: The static bundle is built every time you target a physical device, even in Debug. If you want to save time, turn off bundle generation in Debug by adding the following to your shell script in the Xcode Build Phase Bundle React Native code and images:
    
-
    
-
     if [ "${CONFIGURATION}" == "Debug" ]; then
-  export SKIP_BUNDLING=true
- fi

    As your App Bundle grows in size, you may start to see a white screen flash between your splash screen and the display of your root application view. If this is the case, you can add the following code to AppDelegate.m in order to keep your splash screen displayed during the transition.
    
 
      // Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
   UIView* launchScreenView = [[[NSBundle mainBundle] loadNibNamed:@"LaunchScreen" owner:self options:nil] objectAtIndex:0];

    3. Configure app to use static bundle
    
-
    During the development process, React Native has loaded your JavaScript code dynamically at runtime. For a production build, you want to pre-package the JavaScript bundle and distribute it inside your application. Doing this requires a code change in your code so that it knows to load the static bundle.
    
-
    In AppDelegate.m, change jsCodeLocation to point to the static bundle if you're not in debug mode.
    
-
    #ifdef DEBUG
-  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
-#else
-  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
-#endif

    This will now reference the main.jsbundle resource file that is created during the Bundle React Native code and images Build Phase in Xcode.

    Generating Signed APK

    Android requires that all apps be digitally signed with a certificate before they can be installed, so to distribute your Android application via Google Play store, you'll need to generate a signed release APK. The Signing Your Applications page on Android Developers documentation describes the topic in detail. This guide covers the process in brief, as well as lists the steps required to package the JavaScript bundle.

    Generating a signing key

    You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

    -
    $ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
+
    $ keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
 
    
 
    This command prompts you for passwords for the keystore and key and for the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore.
    
 
    The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

    Learn the Basics

    React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components, state, and props. If you already know React, you still need to learn some React-Native-specific stuff, like the native components. This tutorial is aimed at all audiences, whether you have React experience or not.

    +

    Because typical React Native projects are essentially made up of an Android project, an iOS project, and a JavaScript project, upgrading can be rather tricky. Here's what you need to do to upgrade from an older version of React Native.

    Upgrade based on Git

    -

    The module react-native-git-upgrade provides a one-step operation to upgrade the source files with a minimum of conflicts. Under the hood, it consists in 2 phases:

    -
      -
    • First, it computes a Git patch between both old and new template files,
      • -
    • Then, the patch is applied on the user's sources.
      • -
    +

    The React Native CLI comes with upgrade command that provides a one-step operation to upgrade the source files with a minimum of conflicts, thanks to the rn-diff-purge project.

    +

    1. Make sure your project uses Git

    -

    IMPORTANT: You don't have to install the new version of the react-native package, it will be installed automatically.

    +

    This step applies only to projects that don't use Git. Skip it if yours use it.

    -

    1. Install Git

    -

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native-git-upgrade. Git will also need to be available in the PATH.

    -

    2. Install the react-native-git-upgrade module

    -

    The react-native-git-upgrade module provides a CLI and must be installed globally:

    -
    $ npm install -g react-native-git-upgrade
+
    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"
 
    
-
    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {

    While your project does not have to be handled by the Git versioning system -- you can use Mercurial, SVN, or nothing -- you will still need to install Git on your system in order to use react-native upgrade. Git will also need to be available in the PATH. If your project doesn't use Git, initialize it and commit:
    
+
    git init
+git add .
+git commit -m "upgrade RN"

    3. Run the command
    
+
    After the upgrade is done and conflicts resolved, you can remove the .git directory.
    
+
    2. Run the upgrade command
    
 
    Run the following command to start the process of upgrading to the latest version:
    
-
    $ react-native-git-upgrade
+
    react-native upgrade
 
    
-
    
-
    You may specify a React Native version by passing an argument: react-native-git-upgrade X.Y.Z
    
-
    
-
    Upon completion, run the following command to find your corresponding git patch file.
    
-
    $ ls $TMPDIR/react-native-git-upgrade
+
    You may specify a React Native version by passing an argument, e.g. to upgrade to 0.59.0-rc.0 run:
    
+
    react-native upgrade 0.59.0-rc.0
 
    
-
    To apply the git patch, run git apply <path to patch> inside your project folder.
    
-
    The templates are upgraded in a optimized way. You still may encounter conflicts but only where the Git 3-way merge have failed, depending on the version and how you modified your sources.
    
+
    The project is upgraded using git apply with 3-way merge. That's why it may happen you'll need to resolve some conflicts.
    
 
    4. Resolve the conflicts
    
 
    Conflicted files include delimiters which make very clear where the changes come from. For example:
    
 
    13B07F951A680F5B00A75B9A /* Release */ = {
