# This Week In React #287: Fragment ref, React Compiler, StyleX, React Router, cnfast, Base UI, Remotion, React Aria

## Summary

Weekly roundup covering React and React Native ecosystem news. Key React highlights include the upcoming Fragment ref feature (FragmentInstance) slated for React v19.3, React Compiler updates including a Bun integration and Rust-based compiler progress, React Router 8.0 release (ESM-only, boring-by-design upgrade), StyleX 0.19, Base UI 1.6, and TanStack Table v9 memory improvements. On the React Native side, Reanimated 4.5 adds CSS pseudo-selector support, Expo SDK 56 stabilizes iOS widgets and Live Activities, and VisionCamera enables real-time video processing. The broader ecosystem sees Vite 8.1 with Bundled Dev Mode, Astro 7.0 with ~61% faster builds via Rolldown, TypeScript 7.0 RC (Go rewrite), and a GitHub Actions security tightening that prevents supply chain attacks like those that recently hit TanStack, Nx, and PostHog.

> - **React Router 8.0** — ESM-only, boring-by-design. No breaking changes for most users.
> - **Reanimated 4.5** — CSS pseudo-selector support in RN. Hover, focus, active, and more, now native.
