This week, TanStack Start is once again in the spotlight. The React Compiler in Rust is on its way. React Router and Remix shipped important security patches β update immediately. There's also a fresh batch of releases from TanStack Form, XState Store, shadcn, React Aria, and more.
On the React Native side, this week was dominated by App.js Conf 2026 in KrakΓ³w. Gesture Handler 3.0, Swift Package Manager support for React Native, and Legend List 3.0 were among the highlights, alongside Expo announcements like EAS Observe.

π Deprecating a React component using TypeScript Overload - How to ship a breaking component redesign without renaming it with the usage of TS overload, mark the old API as @deprecated, and let consumers opt into the new version by adding a new prop.
π¦ TypeGPU React - React bindings for TypeGPU - Hooks like useFrame, useUniform, and useRoot to write GPU shaders directly in TypeScript and integrate WebGPU into React components.
Claude writes your code. Claude reviews your code. Claude fixes the review comments. And somehow, you're the one getting paged at 2am when it breaks in prod.
Last week, the community gathered at the App.js Conf happening in KrakΓ³w. We're highlighting three announcements here, since many of the others shipped over the past month and were demoed again on stage. Make sure to catch the rest of the talks through the live stream recordings (Day 1, Day 2).
Major release rebuilt for the New Architecture, dropping Old Architecture support, introducing a new hook-based API which is React Compiler friendly, a new Touchable component with built-in animations and deeper Reanimated integration.
Swift Package Manager support for React Native
Meta + Expo previewed npx react-native spm, which scaffolds SPM config to replace CocoaPods: generates a committable Xcode project, runs codegen, caches XCFrameworks globally. CocoaPods trunk goes read-only Dec 2. Both Cocoapods and SPM work in parallel during the transition.
New Expo production performance monitoring service that tracks real-world startup times, render performance, and bundle load times across devices, with release comparison and per-session investigation. Currently in Private Preview, free up to 10K MAU for at least three months.
