TanStack Start Reaches 1.0

After a year as a release candidate, TanStack Start 1.0 is officially stable. Tanner Linsley explains how it grew out of TanStack Router, and is candid about RSC, which felt like "this box we had to check to be taken seriously as a React framework", and which tanstack.com itself no longer uses. Plus:

• 📊 The same app in Start and Next.js 16.4, benchmarked – Start handled 2.9x-8.6x more dynamic requests and built ~1.7x faster with type-checking included.

• 🚚 Moving over? There are official guides for migrating from Next.js and from the RC. Sarthak Mishra moved his site over from Astro (and explains why) and Lovable offers older projects a migration option (here's how one went).

• 💬 Ryan Carniato called it "a React metaframework with an architecture I can get behind", while in the r/reactjs thread Tanner explained why '1.0' is listed as 1.169 on npm.

IN BRIEF:

• ⚠️ Last week, Next.js patched two critical RCEs, one rooted in React Server Components, and a public PoC is now out. Update Next.js to 16.4.1 or 15.5.28; for other RSC setups, update the react-server-dom-* packages to 19.3.1 (or 19.2.9/19.1.10/19.0.9).

• React DevTools for agents now has official docs, covering how it exposes profiling and component data to coding agents through Chrome DevTools MCP.

• 📱 Expo SDK 58 is out, using the new React Native 0.88, targeting iOS 27 and ready for the iPhone Duo on day one.

• React Native for Web has active maintainers again and is moving to the React Foundation's GitHub org.

• TypeScript 7.1 is now in beta, adding a programmatic API and more speed. Type-checking MUI's docs is 1.9x faster and uses half the memory.

Pixel: Build Graphical Applications in the Terminal — Like Ink, but with "pixel perfect" graphics. It's a React renderer that draws rounded corners, gradients and proper fonts in terminals that support the Kitty graphics protocol, and that can even embed Chromium WebViews to run web apps in a pane(!)

TanStack Hotkeys Beta: A Type-Safe Library for Keyboard Shortcuts — Hotkeys takes care of the fiddly, cross-platform edge cases of keyboard shortcuts, sequences, and user-recorded hotkeys. The beta adds scopes, so that, say, a dialog's Escape doesn't close the panel behind it. Try the demo on the homepage.

React Router 8.5 Hands View Transitions Over to React — Its own view transition APIs are deprecated in favor of React 19.3's <ViewTransition>. Migrating starts with wrapping an <Outlet> and removing the old props and state styling. There's also an unstable 'API-only' mode that serves static HTML but keeps a server for loaders and actions.

Fancy making a little music with React? Strudel Flow 2 is an open source React app built with React Flow and shadcn/ui. Connect instruments and effects to generate Strudel code, or load a community patch and start turning knobs.

The source code offers a neat extension point: define an instrument or effect in a small .node.ts file, then supply a React component for a custom interface. As the team says, "coding is a fun thing to do for its own sake." 🤘
