Ruslan Lesiutin c21ce4a396 feat: display message if user ended up opening hook script (#31000)
In https://github.com/facebook/react/pull/30596 we've moved console
patching to the global hook. Generally speaking, the patching happens
even before React is loaded on the page.

If browser DevTools were opened after when `console.error` or
`console.warn` were called, the source script will be `hook.js`, because
of the patching.

This is because ignore listing is not applied retroactively by Chrome
DevTools.
If you had it open before console calls, Hook script would be correctly
filtered out from the stack:

I had hopes that the fix for
https://issues.chromium.org/issues/345248263 will also apply ignore
listing retroactively, but looks like we need to open a separate feature
request for the Chrome DevTools team.

With these changes, if user attempts to open `hook.js` script, they are
going to see this message:

This is the source code for the React DevTools browser extension.

Installation

The easiest way to install this extension is as a browser add-on:

Local development

You can also build and install this extension from source.

Prerequisite steps

DevTools depends on local versions of several NPM packages1 also in this workspace. You'll need to either build or download those packages first.

1 Note that at this time, an experimental build is required because DevTools depends on the createRoot API.

To install all necessary dependencies, run the following command from the root of the repository:

yarn install

Build from source

To build dependencies from source, run the following command from the root of the repository:

yarn build-for-devtools

Download from CI

To use the latest build from CI, run the following commands starting from the root of the repository:

cd scripts/release
yarn install
./download-experimental-build.js

Build steps

Once the above packages have been built or downloaded, you can build the extension by running:

cd packages/react-devtools-extensions/

yarn build:chrome # => packages/react-devtools-extensions/chrome/build
yarn run test:chrome # Test Chrome extension

yarn build:firefox # => packages/react-devtools-extensions/firefox/build
yarn run test:firefox # Test Firefox extension

yarn build:edge # => packages/react-devtools-extensions/edge/build
yarn run test:edge # Test Edge extension
