This Week In React #182: v18.3, useDeferredValue, 3D, Metro, Worklets, TC39, TypeScript, Effect, Rspack, GraphQL...

Hi everyone!

This week we have a nice Next.js release and many interesting community blog posts.

We can also feel that the React core team is working hard to polish the remaining details for React 19. Unexpectedly, a v18.3 is finally planned with extra warnings. React Native 0.74 is also around the corner.

This week I'd like to introduce you to ECMAScript News. It's my favorite newsletter to keep up to date with ES, TC39, JS tooling, and runtimes.

Next week we have React Connection and React Native Connection conferences in Paris. See you there for those that attend πŸ‘‹. You can still get a -20% discount with my partner code "TWIR".

Next.js 14.2

Next.js 14.2

Until we get React 19 and Next.js 15, this new minor version includes development, production, and caching improvements. The highlights are:

  • Turbopack (RC): 99.8% of tests passing for next dev --turbo
  • Build / Production Improvements: Reduced memory usage
  • Caching Improvements: Configurable client-side cache revalidation with staleTimes
  • Errors DX: Better hydration mismatch messages

I’m excited to see a great React hydration mismatch error dialog already implemented in Next.js! As I write this, Turbopack is 99.9% ready for development usage (6 integration tests missing). For build usage, it’s 75% ready so we’ll have to wait a bit more.
