Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/36623 Changelog: [General][Changed] - The default `metro.config.js` in apps now extends `react-native/metro-config`, and should be updated in existing apps. ~~`react-native/rn-get-polyfills.js` is removed and should be updated to `react-native/js-polyfills` in existing apps (this is part of the new default config).~~ #publish-packages-to-npm ## Context ### React Native Metro config → React Native repo (https://github.com/facebook/react-native/pull/36502) We (the React Native team) are aiming to relocate the default Metro config for React Native out of `react-native-community/cli-plugin-metro` and **into the React Native repo + app template** as a new `react-native/metro-config` package. This is the first (and minimum viable) phase we can ship to separate the release process of Metro from RN CLI in order to reduce coupling and iterate faster for our users. **See full motivation, design, and test plan (which previewed the CLI bump) here: https://github.com/facebook/react-native/pull/36502** ## Changes NOTE: This PR is pending the inclusion of a bump to `react-native-community/cli`, and will be sequenced after https://github.com/react-native-community/cli/pull/1875 is merged. - Upgrade `react-native-community/cli` to `11.0.0`, upgrade all `metro` packages to `0.76.0` (version distributed in this CLI release). - Update the `metro.config.js` file in `packages/react-native/template/`. - Now merges defaults from `react-native/metro-config`, and can be used with CLI >= 11.0.0. - Update the `metro.config.js` files for `packages/react-native/` and `packages/rn-tester/` (these are integration test locations). - Now merges defaults from `react-native/metro-config`, and can be used with CLI >= 11.0.0. Changes to `react-native/metro-config` — `0.72.1` (prepared but not depended on yet): - Export `mergeConfig` util (removing direct `metro-config` dependency in consuming projects). - Explicitly depend on `metro-react-native-babel-transformer` and `metro-runtime` (transitively included today).

React Native

React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 12.4 and Android 5.0 (API 21) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repo, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in this discussion repo.
