- Instead of reconnecting ports from devtools page and proxy content
script, now handling their disconnection properly
- `proxy.js` is now dynamically registered as a content script, which
loaded for each page. This will probably not work well for Firefox,
since we are still on manifest v2, I will try to fix this in the next
few PRs.
- Handling the case when devtools page port was reconnected and bridge
is still present. This could happen if user switches the tab and Chrome
decides to kill service worker, devtools page port gets disconnected,
and then user returns back to the tab. When port is reconnected, we
check if bridge message listener is present, connecting them if so.
- Added simple debounce when evaluating if page has react application
running. We start this check in `chrome.network.onNavigated` listener,
which is asynchronous. Also, this check itself is asynchronous, so
previously we could mount React DevTools multiple times if navigates
multiple times while `chrome.devtools.inspectedWindow.eval` (which is
also asynchronous) can be executed.

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
