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 My books are already outdated, but they look good here.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. 😆 😎

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!

Exciting! On top of this, I will introduce HeyApi @mrlubos and how it feels after using it one year. What not to do in TanStack Query if you are using @tan_stack Router or Start? And how I use coding models with TanStack Query. You must see this presentation. It will change you.

Everyone, don't forget to take a break after working so hard last year and getting ready for grinding in this 2026. 🤿 with @aurorascharff at #Palawan

@TomasJansson @shadcn @radix_ui @base_ui More support in BaseUI than RadixUI, but the most essential thing in our existing application is that the infamous bug where the "carousel component's click does not work in production" is fixed now. I had to create my own carousel before, but I am using the real one in prod now.

@DevlinDuldulao @shadcn @radix_ui @base_ui What is the advantage of @base_ui vs @radix_ui ?

A new machine plus a successful migration of our existing app's @shadcn components from @radix_ui to @base_ui means time to add this sticker 😌.
