Say hello (again?) to React 19

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.

My React Tech Stack for 2025 — After a year of research, building React apps, and creating a full-stack course, Robin shares what he’s settled on as his broader stack going forward for React apps into the new year. There’s little that’s surprising here, but it’s good to see all these suggestions come together in one place.

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.
