Suppose that you have this setup for devtools test: ``` // @reactVersion <= 18.1 // @reactVersion >= 17.1 ``` With previous implementation, the accumulated condition will be `"<= 18.1" && ">= 17.1"`, which is just `">= 17.1"`, when evaluated. That's why we executed some tests for old versions of react on main (and failed). With these changes the resulting condition will be `"<= 18.1 >= 17.1"`, not using `&&`, because semver does not support this operator. All currently failing tests will be skipped now as expected. Also increased timeout value for shell server to start
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
