Builds on #37048 by replacing `any`-based Bridge and Wall boundaries with typed `mixed` values and explicit runtime validation. Invalid messages and post-shutdown operations now throw, while shutdown reliably flushes queued messages even if cleanup fails. Strengthens the DevTools Bridge and Wall contracts: - Models event dictionaries as event-to-payload maps, using `void` for events without payloads. - Types `send(event, payload?)` directly, eliminating runtime payload-arity handling. - Replaces broad `any` transport types with `mixed` and boundary validation. - Throws on invalid lifecycle usage instead of warning or silently returning. - Ensures shutdown flushes queued messages even when Wall cleanup fails. - Updates Wall implementations and adds Bridge lifecycle coverage.
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
