REACT DEVTOOLS GOES AUTOMATED, NATIVE DROPS LEGACY CRUFT

By RepoJournal · Filed · About Meta

React's DevTools CDT integration now runs full end-to-end tests in CI, while React Native nukes three deprecated APIs in the same sweep.

The React team shipped automated E2E coverage for react-devtools-cdt-mcp [1], adding a GitHub Actions workflow that boots a fixture app and validates third-party tool discovery, profiling, and DOM inspection through the actual Chrome DevTools CLI [2]. This moves DevTools testing from manual verification to continuous validation, catching integration breaks before they ship. Meanwhile, React landed experimental support for parentEnter and parentExit props on nested ViewTransition components [3], letting you animate individual list items when a parent boundary enters or exits without manually coordinating sibling animations. On the Native side, React Native is cleaning house: DrawerLayoutAndroid is now formally deprecated [4] in favor of the cross-platform react-native-drawer-layout, ScrollView's keyboardShouldPersistTaps no longer accepts booleans [5], and the legacy FANTOM_ENABLE_CPP_DEBUGGING environment variable is gone [6]. The animation backend also switched to run from Fabric's frame callback instead of a custom choreographer [7], reducing coupling and simplifying invalidation logic.
