Thanks, @voxxed_thess, for taking this photo. My books are already outdated, but they look good here. And I look like a local rapper from Manila. 😆 😎

This is a big one. Making Next.js deploy well on every major cloud has been a real focus, and the team has been working closely with partners to get it right.

Our React Senior Bootcamp kicks off next week! 🚀 3 days with @aurorascharff: covering SSR, server components, Suspense, state patterns, forms, testing, security & more. Already have a bundle? Don’t forget to reserve your spot! New? Upgrade or join today for live prep toward the Senior Exam! 🔗 certificates.dev/react

Wrote up the full walkthrough with code examples ↓ aurorascharff.no/posts/error-ha…

𝚛𝚎𝚊𝚌𝚝-𝚎𝚛𝚛𝚘𝚛-𝚋𝚘𝚞𝚗𝚍𝚊𝚛𝚢 is great for declarative error handling, but it breaks with Server Components: it swallows 𝚗𝚘𝚝𝙵𝚘𝚞𝚗𝚍() and 𝚛𝚎𝚍𝚒𝚛𝚎𝚌𝚝(), and 𝚛𝚎𝚜𝚎𝚝() can't re-fetch server data. Next.js 16.2 𝚌𝚊𝚝𝚌𝚑𝙴𝚛𝚛𝚘𝚛: framework-aware, 𝚛𝚎𝚝𝚛𝚢() re-fetches RSC data, and internal errors propagate correctly. Blog post + demo in the thread ↓

View Transitions just got simpler with Next.js 16.2. <𝙻𝚒𝚗𝚔> now has a 𝚝𝚛𝚊𝚗𝚜𝚒𝚝𝚒𝚘𝚗𝚃𝚢𝚙𝚎𝚜 prop. Tag your navigation with a type, and <𝚅𝚒𝚎𝚠𝚃𝚛𝚊𝚗𝚜𝚒𝚝𝚒𝚘𝚗> picks the right animation.

Lots of good stuff in here! 🖤

Next.js 16.2 • Up to ~60% faster rendering • Up to ~400% faster 𝚗𝚎𝚡𝚝 𝚍𝚎𝚟 startup • Server Function 𝚍𝚎𝚟 logging • Redesigned error page • Better hydration errors • 𝙴𝚛𝚛𝚘𝚛.𝚌𝚊𝚞𝚜𝚎 display in error overlay nextjs.org/blog/next-16-2

I wanted my editor to match the Vercel docs code blocks. Found a great theme by @natemcgrady based on the Vercel ray.so theme, forked it, tweaked it to get closer to the docs, and added a light variant. Going to use it for all my demos, videos, and presentations. Available for VS Code and Cursor.

A Next.js feature I think more devs should know about: 𝚝𝚢𝚙𝚎𝚍𝚁𝚘𝚞𝚝𝚎𝚜: 𝚝𝚛𝚞𝚎 PageProps auto-types your params and searchParams. Route<T> catches broken links at build time.

I'm excited to share that I'm joining @vercel as a DX Engineer! For the past few years, I've been writing blog posts, giving talks, and building demo apps around React and Next.js, all on my own time, because I genuinely love it. The deep dives into patterns, the experiments with new APIs, the content that helps other developers get unstuck: that's been the most rewarding part of my career so far. Now I get to do it as part of the team that builds the framework. Can't wait to start this journey, teach what I learn along the way, and help make Next.js and Vercel products as good as possible for everyone. My inbox is always open.

The Async React design layer in practice. Components handle async coordination and UI internally: • Pending states via useTransition • Optimistic updates and rollback via useOptimistic Consumers just pass an action. Two examples with live demos ↓ aurorascharff.no/posts/building…

@aurorascharff @ReactVienna @TkDodo @farisaziz12 @glnnrys I should have ordered pizza here. @nosthrillz

It was great to hang out with these people after @ReactVienna last week! Thanks for the tour @TkDodo @farisaziz12 @glnnrys @devlinduldulao

The 👸 RSC Queen @aurorascharff is back with her live coding demo here at @ReactVienna 🙌🏽.

We are here @ReactVienna with @aurorascharff, @glnnrys, @hola_soy_milk, @TkDodo, @farisaziz12, and @nikgraf. Thanks for inviting us, and thank you @myadverity and @KetryxHQ for making this happen.

The State of React 2025 survey is out ☺️ I had the chance to write the conclusion, sharing some reflections on the past year in React and where things might be heading next. 2025.stateofreact.com/en-US

Though the hard part isn't writing tests anymore. It's defining what you actually want tested.

In an ai-driven development workflow, Tests are your specifications. The better your specs (tests), the better the AI can work for you without introducing regressions.

If you haven’t yet, check out the new useOptimistic docs. There’s a ton of great use cases, with interactive sandboxes to try things out! react.dev/reference/reac…

@ReactMiamiConf I will do a mini version of the enterprise app I built for a customer and the process of using HeyApi codegen and good prompting for copilots. This development pattern is so good that I would never go back in the old way of writing React with TanStack Query.

Bienvenido @devlinduldulao!! Devlin's here to give a deep dive on TanStack Query including core patterns such as queries, mutations, cache tuning, and advanced features!
