[DevTools] fix: dedupe file fetch requests and define a timeout (#34566)
If there is a large owner stack, we could potentially spam multiple
fetch requests for the same source map. This adds a simple deduplication
logic, based on URL.

Also, this adds a timeout of 60 seconds to all fetch requests initiated
by fileFetcher content script.

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
