* Lower minimum Node.js version to 20.19.4 (#52678) Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/52678 From partner feedback, there's still appetite to support Node 20.x for the next <1y of life. Lower min version to `20.19.4` (Jul 2025) and widen test matrix in CI. Changelog: [General][Breaking] - Our new minimum Node version is Node.js 20 (Overrides #51840) Reviewed By: cortinico Differential Revision: D78494491 fbshipit-source-id: c8d9dc6250cb11f8a12ca7e761b65f4a8dae9265 * Bump Metro to ^0.83.1, lower minimum Node.js version to 20.19 Summary: Metro release notes: https://github.com/facebook/metro/releases/tag/v0.83.1 The only public-facing change is a lowering of the minimum Node.js version from 22.14 to 20.19. This will need picking to RN `0.81-stable` Changelog: [General][Changed] Metro to ^0.83.1 Reviewed By: huntie Differential Revision: D78895160 fbshipit-source-id: b9ccffe972249b73897f51c14873861e57a97161 * Do not setup-node twice in test_js (#52737) Summary: I've noticed that test_js (20) and test_js (24) are actually running on Node 22. That's because the `yarn-install` action is invoking setup-node again with the default value (22). This changes it. Also I'm cleaning up the workflows so that every `yarn-install` invocation is happening just after the `setup-node` invocation. ## Changelog: [INTERNAL] - Pull Request resolved: https://github.com/facebook/react-native/pull/52737 Test Plan: CI which will most likely be red for test_js (20) so will need a follow-up Reviewed By: cipolleschi Differential Revision: D78664671 Pulled By: cortinico fbshipit-source-id: c73390930d1511d1bf0f2d4ea92e83f50b10247f --------- Co-authored-by: Alex Hunt <huntie@meta.com> Co-authored-by: Rob Hogan <robhogan@meta.com> Co-authored-by: Nicola Corti <ncor@meta.com>

Contributing
Source repo
Source code for this package lives in the facebook/react-native-devtools-frontend repo. See below for how we build and check in changes.
Updating the frontend assets
The compiled assets for the debugger frontend are periodically checked into this package under the dist/ folder. To update these, run node scripts/debugger-frontend/sync-and-build from the root of your react-native checkout.
# For main
node scripts/debugger-frontend/sync-and-build --branch main
# For stable branches (e.g. '0.73-stable')
node scripts/debugger-frontend/sync-and-build --branch 0.73-stable
By default, this will clone and build from facebook/react-native-devtools-frontend.
