Next.js 16.3 is now in preview and will be stabilized in the coming weeks. This sneak peek focuses on a new opt-in feature called Instant Navigations, improving on top of Cache Components. This addresses the loudest criticism of the App Router: server-driven navigations feel like clicking a website, not an app.
With this new feature, you will have to make a very explicit choice whenever you await some data on the server, nicely presented in an Instant Insights dev panel to surface slow navigations:
Stream with
Cache with βuse cacheβ
Block with export const instant = false;
Thereβs more:
Playwright instant() test helper - Assert what must be instantly visible after a link click.
Partial Prefetching - Instead of prefetching a page per link in the viewport, Next.js will now prefetch a reusable shell per route. You can still prefetch links more aggressively (opt-in).
π Next.js 16.3: AI Improvements - Bundled docs, first-party skills, Agent Browser with React introspection, actionable errors, improved MCP server, and docs as Markdown.
π Turbopack: What's New in Next.js 16.3 - Reducing dev server memory by up to 90%, up to 5.5x faster rebuilds with persistent cache, experimental React Compiler in Rust, import.meta.glob API, faster HMR and dev startup.

π React Docs - use() API Reference - This React API docs page has been entirely rewritten, also explaining important concepts such as how Promises must be cached on the client.
π ESLint Plugin React - ESLint v10 compatibility progress - React users of this ESLint plugin have been stuck on ESLint v9 for a while. Thankfully, v10 support has just been merged into the Import plugin, which should also unlock the React plugin compatibility.
π Vercel and Shopify are rebuilding Hydrogen - Vercel is helping Shopify improve its proprietary Hydrogen e-commerce framework. Initially based on React/Remix, the new version should be more portable, supporting Svelte, Nuxt, Next.js, and various server runtimes.
π Rolldown Pulls Rust React Compiler Integration After Binary Size Increase - Nicely summarize the tradeoffs of integrating Rust extensions in frontend tools, and whether itβs a good idea for a framework-agnostic tool to have a first-class integration with React. Oxc blocked the integration until itβs slimmed down (in progress), while Rspack chose to ship the Compiler now and optimize incrementally.
π React Compiler Is A Retrofit - Argues that, unlike Solid/Svelte, the React Compiler optimizes a runtime model that was not initially designed around a compiler. It can increase bundle size and make the memoization contract of your APIs less explicit. It is safer to use it as a linter rather than a compiler.
π Different hydration and rendering strategies - Explains how much JS runs between "looks ready" and "actually works", across every rendering strategy, including non-React ones.
π React Testing Questions That Trip Up Engineers - Covering the role of act(), testing implementation details, overmocking, and challenges like testing IntersectionObserver or drag-and-drop.
π¦ Astryx - Metaβs open-source design system, built on React and StyleX - Meta released an OSS beta version of their design system, built over 8 years and powering 13000+ internal apps, using StyleX atomic CSS-in-JS library. Itβs not a headless lib, but highly themable with design tokens and the ability to eject the components to customize them entirely.
π¦ shadcn/ui - Chat interface components, @shadcn/react - This Chat UI update also takes the opportunity to introduce a new package for unstyled, headless React components. For now, thereβs only a single primitive, but more could come later?
π¦ Storybook for TanStack React - A dedicated Storybook framework for TanStack-powered React apps. This provides first-class, type-safe support for TanStack Router, Start, and Query.
Your company needs a new CRM? Point them to a popular open-source CRM written in React, built with battle-tested libraries (Tailwind CSS, react-router, TanStack Query, react-hook-form) and powered by Supabase.
Best of all: for every customization they'll need, you can delegate the work to Atomic CRM's agentic harness, an AI specially trained to build robust, maintainable and usable CRMs.
By the way, Atomic CRM ships with free SSO and you can host it anywhere, so your data stays yours. Check out the demos!β
It feels like Expo SDK 56 just got released, and weβre already on SDK 57, even skipping the beta phase!?
Since RN 0.86 got released with no breaking changes, the Expo team decided to cut the new release sooner than usual. Itβs a test of a new release cadence that will follow RN releases more closely. React Nativeβs move towards stability should make it easier to offer the latest changes almost immediately. Why not do it as a part of the SDK 56 update, then? There are still many changes, and itβs better to make the upgrade intentional to avoid unexpected errors.
RN 0.86 features are now available in Expo: first-class edge-to-edge support on Android, light/dark mode emulation in React Native DevTools, and rendering, layout, and animation fixes. Expo 57 also comes with a list of various Expo-related improvements.

π Read Online Hi everyone, Seb and Jan here π! This week we have React and Next.js security patches. React Aria becomes first-class in shadcn. A benchmark grades coding agents at real React tasks. The rise of TSRX and its upcoming framework. On the mobile side, Swift Package Manager support is finally coming. A TC39 meeting is in progress; we'll share the proposal updates next week. Oxlint type-aware linting is ready for prime-time. Meanwhile, Yuku explains how it outperforms Oxc at parsing...
π Read Online Hi everyone, Konrad and Szymon from Software Mansion here. This week, the React team documented its reorganization into working groups. The docs got a new section on what actually activates a Suspense boundary. A few thoughtful posts weighed React against lighter alternatives like HTMX and SolidJS. On the React Native side, two RFCs caught our eye: media queries in StyleSheet and ViewTransition support, plus a Nitro Modules rewrite of Rive that's up to 94x faster. Also worth...
π Read Online Hi everyone, Seb and Jan here π! Things are relatively calm on the React side this week, but it's still worth highlighting Base UI becoming the default headless lib in shadcn, and Vinext getting close to production-ready. On the mobile side, React Native 0.87 went full Marie Kondo. We also have a nice preview of React Navigation 8 and the relentless stream of AI tooling updates. TypeScript 7.0 is out, and it's 10x faster. Ecma has officially approved ES2026, and HTTP is finally...
