README.md

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.

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 command from the root of the repository:

./scripts/release/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
You can’t perform that action at this time.
