## Summary
resolves #24522
To upgrade to Manifest V3, one of the biggest issue is that we are no
longer allowed to add a script element with code in textContent so that
it would run synchronously. It's necessary for us because we need to
inject a global hook for react reconciler to detect whether devtools
exist.
To do that, we'll leverage a new API
`chrome.scripting.registerContentScripts` in V3. Particularly, we rely
on the "world" option (added in Chrome v102
[commit](e5ad3451c1))
to run it in the "main world" on the page.
This PR also renames a few content script files so that it's easier to
tell them apart from other extension scripts and understand the purpose
of each of them.
Manifest V3 is not yet ready for Firefox, so we need to keep some code
for compatibility.
## How did you test this change?
`yarn build:chrome && yarn test:chrome`
`yarn build:edge && yarn test:edge`
`yarn build:firefox && yarn test:firefox`
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
