React v19 Released (For Real This Time) — An early Christmas present! First teased in the React Labs February 2024 post, React 19 has been cooking for long enough (and in beta for 8 months) there’s already a wealth of content out there, like the React 19 upgrade guide, an explanation of the compiler, cheat sheets, and a roundup of what’s new in React 19. It’s here, and it’s time to re-explore Actions, the new hooks, use, Server Components, and more.

Next.js 15.1: Now Officially Supporting React 19 — As (almost) the de facto React framework, it’s no surprise a Next.js release quickly followed the React 19 announcement. As well as React 19 support, there are improvements for debugging errors (shown in this post), after() is now stable, and forbidden() and unauthorized() are two new experimental ways to trigger 403 and 401 errors.

Ref Callbacks, React 19 and the Compiler — Two years since his first article on callback refs, it turns out, in hindsight, some of the things included in that piece “were not 100% correct”. It’s time to revisit the subject.
