In RSC and other stacks now we use a lot of `ReactFunctionLocation` type to represent the location of a function. I.e. the location of the beginning of the function (the enclosing line/col) that is represented by the "Source" of the function. This is also what the parent Component Stacks represents. As opposed to `ReactCallSite` which is what normal stack traces and owner stacks represent. I.e. the line/column number of the callsite into the next function. We can start sharing more code by using the `ReactFunctionLocation` type to represent the component source location and it also helps clarify which ones are function locations and which ones are callsites as we start adding more stack traces (e.g. for async debug info and owner stack traces).
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
