Been working on a new microsite to teach Next.js patterns, and I just published a new one: "Sharing data with Client Components" See how to use promises to keep your page unblocked so it can be rendered (or prerendered) as early as possible. Enjoy! next-16-recipes.vercel.app/sharing-data...

Researchers have found two new vulnerabilities in React Server Components while attempting to exploit the patches last week. These are new issues, separate from the critical CVE last week. The patch for React2Shell remains effective for the Remote Code Execution exploit.

✨ Welcoming @aurorascharff.no to React Summit! Software developer, Microsoft MVP, and React Certification Content Owner at http://certificates.dev - Aurora is shaping how developers learn modern React and Next.js. Expect clarity, depth, and practical insights. See you in

My talk at @nextjs.org Conf 2025 is now available! I cover composing client and server components, structuring component-level architecture, and using the new Next.js 16 “use cache” directive to handle static and dynamic content efficiently. www.youtube.com/watch?v=iRGc...

⚛️ @aurorascharff.no, a senior dev consultant and React certification lead, discusses how the “Async React” era signals a fundamental shift in how development teams build software: blog.logrocket.com/the-next-era...

There is critical vulnerability in React Server Components disclosed as CVE-2025-55182 that impacts React 19 and frameworks that use it. A fix has been published in React versions 19.0.1, 19.1.2, and 19.2.1. We recommend upgrading immediately. react.dev/blog/2025/12...

I cover Async @react.dev primitives like useTransition, useOptimistic, Suspense, and use() and how they simplify async coordination. React and its ecosystem are evolving for reliable async and a declarative DX. Loved writing this for @logrocket.bsky.social.

Welcome to Bluesky, @orcdev.bsky.social ! 👋 For the Horde! ⚔️

Going back through @ricky.fm's Async React as I prep an internal talk, and this part is insanely good, felt like it deserved a reshare🔥 youtu.be/p9OcztRyDl0?...

React Free Weekend is LIVE!

Updated my blog post on dynamically generating PWA icons for different environments in Next.js! Now uses Serwist instead of next-pwa, making it easier to work with Next.js 16's defaults. aurorascharff.no/posts/dynami...

Following up on my demo of cacheComponents + next-intl, I wrote a blog post reflecting on the problem's background and better explaining the solution! aurorascharff.no/posts/implem...

Created a simple demo on how to use cacheComponents with next-intl ⭐️ next-intl-cache-components.vercel.app/en As mentioned in this discussion on X, it is a workaround and might get easier in the future! x.com/aurorascharf...

Next.js 16 • Cache Components • Turbopack enabled by default • Turbopack file system caching (beta) • Optimized navigations and prefetching • Improved caching APIs • Build Adapters API (alpha) • React 19.2 nextjs.org/blog/next-16

this looks like it'll be a banger release nextjs.org/blog/next-16...

On my way to Next.js Conf ✨ Next.js keeps evolving with new ways to structure and optimize apps. I’ll share practical patterns for composition, caching, and architecture to make apps more efficient and maintainable. Looking forward to meeting everyone! Watch online for free → nextjs.org/conf

Here's the code for my Async React demo: github.com/rickhanlonii...

Lovely view here early morning at the Westin in Henderson, Nevada. So excited for the next couple of days of #ReactConf 🤩

Async operations don’t have to mean flickering UIs and messy state management. @aurorascharff.no (Crayon Consulting) shows how concurrent rendering + Actions fix these pain points in React 19, and what’s next with View Transitions. ▶️ youtu.be/I3AsmAWWGEs

Really excellent React / Next.js Server Components workshop this morning from @aurorascharff.no - learned a ton that I'll be applying to SimpleRSS! 🙂 She managed to squeeze a ton in even with the building briefly catching fire and being evacuated (for real). #ReactAlicante

React 19.2 is now available! This release includes Activity, useEffectEvent, React Performance Tracks, partial pre-rendering, and more: react.dev/blog/2025/10...

React Cheatsheet - Part 2 📜 Speed up your UI with `useDeferredValue` and `useOptimistic` ⚡ Defer expensive renders to keep your app responsive and show instant updates while async tasks complete. Smooth, seamless, and user-friendly! 👩‍💻

We're excited to announce React Conf speakers from some of your favorite React frameworks and build tools like @expo.dev @nextjs.org Parcel @reactrouter.com @redwoodjs.com Rock @tanstack.com

I will be speaking alongside @p4p8.bsky.social at React Conf in under two weeks! Can’t wait to showcase some of the awesome stuff @redwoodjs.com has to offer.

The real innovation in UI libraries will be scheduling. The goal for my react conf talk next month is to explain why you should use all these async Fiber features because scheduling updates is the biggest performance problem in your app - no matter what library you use.

Exciting update! I’m so proud to announce after months of hard work that the React Senior Developer Exam - the final step in the React certification path I’ve been working on with @certificates.dev is officially live! 📷 certificates.dev/react More info & discount code 🧵👇

Ready to Go Senior with React?🚀 Take a sneak peek at the React Senior Certification Self-Study Training - made for developers building ambitious apps and ready to get their skills officially recognized. Each chapter includes: 🔹 Lessons 🔹 Pop Quiz 🔹 1–2 Hands-on Coding Challenges

The React Senior Certification is launching tomorrow! Here’s a sneak peak into the first training chapters.

We are at #ndccph for a React Router v7 talk by the RSC Queen 👸 @aurorascharff.no. How to migrate from v6 to v7 and why you should migrate.

Every day I hear questions about how you should structure your app or what stage management library to use. I rarely hear about how you should transition part of the UI to the next, or when spinners make sense vs skeletons. Actually I’ve never heard that.

I think at this point Aurora understands transitions and optimistic better than I do, watch this talk

I gave a talk on modern React patterns, including concurrent features, Actions, and the new <ViewTransition> component, at @reactuniverseconf.com last week. Watch the talk here! www.youtube.com/watch?v=I3As...

The new talk ViewTransition in React of the RSC Queen 👸 @aurorascharff.no is about to start. Live coding while explaining things the entire talk, no slides. 🤯 @reactuniverseconf.com

Let's talk about why batched transitions are usually better. Here is a cart where changing the quantity updates the total. The item subtotal and cart total update async. Take a second to think of what should happen if you increase the quantity:

📢 Don’t miss out! @aurorascharff.no invites you to her talk: "Building Interactive Async UI with React 19 and Ariakit." Join us at React Advanced London — happening Nov 28 & Dec 1 at the former Brewery and online.

Me and @devlinduldulao.bsky.social are on our way to @reactuniverseconf.com 🤩 Looking forward to presenting a fresh talk on Thursday!

React Cheatsheet📜 Unlock Concurrent Features in React to build faster & responsive apps! 🔹useTransition marks lower-priority updates to keep the interface snappy, & synchronize async operations to the UI 🔹Suspense provides clean, declarative loading states for async data & lazy-loaded components

Wrote a blog post on @certificates.dev about React’s `Children` utilities and `cloneElement` API. It turns out that the docs themselves contain a lot of interesting information about common component patterns!

I heard some complaints about React batching transitions (mostly on twitter), so I jumped over to the bad place and explained why batching transitions by default is good actually: x.com/rickhanlonii...

My talk at WeAreDevs World Congress on building interactive, asynchronous UI with React 19 and @ariakit.org is now available! Watch it here: www.wearedevelopers.com/en/videos/15...
