TanStack Start 1.0 is finally stable, a client-first alternative to server-first React frameworks.
On mobile, Expo will maintain React Native Web under the React Foundation. Tamagui v3 and One v2 are out. React Native 0.88 is at RC5, so it should land very soon!
Deno is joining Cloudflare. JPEG XL lands in Chrome and Firefox. TypeScript is getting ported to Rust, twice.
Your React app deserves the model that fits the job. TrustedRouter gives your backend hundreds of models through one OpenAI-compatible API. Keep your OpenAI SDK, add your key, and change the base URL.
Choose providers by price, speed, and privacy. Set a minimum privacy level and select confidential routes for sensitive requests. The router runs in attested confidential compute, with public evidence you can verify.
The full-stack framework is officially stable and production-ready, supporting both React and Solid. It has already been used on millions of apps during its beta/RC phase. As its π launch video puts it: "Feels like building a SPA. With the whole server behind you".
Client-first: SPA-style routing, state and caching, with server rendering, streaming and typed server functions.
Type-safe end-to-end: route params, search params, loader data and server function inputs are all typed, keeping changes consistent for both humans and agents. Type checking speed has been thoroughly optimized.
Agent-ready: packages ship TanStack Intent skills, so agents can learn Start's APIs and best practices.
RSC is opt-in: supported, but the team removed it from tanstack.com because it made the codebase harder to reason about.
Deploy anywhere with Vite and Nitro. Rsbuild is also supported.
π¬ React RFC - React work counters - Suggests improving the production observability of React by exposing metrics such as number of re-renders, setState calls or commits. I like the idea of giving metrics for agents to hill-climb and optimize against.
π MobX PR - MobX React plugin - An upcoming bundler plugin will help MobX and the React Compiler coexist. Wraps components in observer(), adds "use no memo" directives, turns async methods into MobX flows.
π Next.js - Upcoming security update - Planned for October 14: 2 critical and 1 high-severity vulnerabilities in upstream dependencies.
π Can we Make React Faster using the React Compiler? - Explains what the compiler outputs, how it works, and then prototypes various optimizations: component inlining, Million.js-style blocks, Solid-like list selection, automatic context and Zustand selectors...
π className Considered Harmful - How design systems drift when components accept className, and how popular design systems restrict it. Why not a DANGEROUS_className prop π€.
Put your coding agent to work on the unit tests you've been meaning to fix. Help it find missed edge cases, strengthen weak assertions, and remove redundant or outdated tests and assertions.
βWallaby for Coding Agents π€ gives your agent live feedback on how the code actually behaves. Use /wallaby improve to strengthen existing tests and /wallaby write to write new ones like an expert developer using Wallaby.
Works with your existing JavaScript, TypeScript, and Python tests in Codex, Claude Code, Cursor, GitHub Copilot, and more. Free for everyone during the beta.
π HTML PR - AsyncContext integration - Still TC39 stage 2, this exciting feature is actively worked on, in particular its integration with web platform APIs.
π£ Deno is joining Cloudflare - The Deno team is joining to work on the Workers and toward making the Durable Objects programming model self-hostable. The Deno runtime and Deno Deploy will be sunset.
π The best way to use icons in Web UIs - Using icons as CSS design tokens, inserted and tweaked with pseudo-elements, masks, and style queries.
π Iframes that finally fit their content - Chrome 154 ships frame-sizing: content-height. Iframes can now adjust their size without the postMessage + ResizeObserver dance.
π JPEG XL finally lands in Chrome 155 and Firefox 158. Safari already has partial support.
π Read Online Hi everyone, Seb and Jan here π, earlier than usual this time π€ͺ Wow, 300 issues already! Time flies, and thanks for reading along π It's a big week, with major releases from the Next.js and TanStack teams. We also put the spotlight on recent React Foundation activity. On mobile, Skia 3.0 is out! Shopify and Coinbase both recently announced moving away from React Native, a trend worth watching. Callstack officially launched an AI model specialized in React Native. There are other...
π Read Online Hi everyone, Seb and Jan here π! This week we have 2 major releases in the React ecosystem: Panda CSS v2 and Vinext v1. On the mobile side, RN is getting support for variable font and Android Activity Result. Lynx v4 is out. Lucent is a new way to write native modules. Iβm particularly excited about the TC39 meeting happening right now. Many proposals progressed, including my favorite one: Composites moved to stage 2! Let's dive in! πΈ Sponsor The React framework for MCP Apps MCP...
π Read Online Hi everyone, Seb and Jan here π! This week is rather quiet on the web side. Astro's React integration keeps ramping up. Redux is working on significant performance improvements for large apps. On mobile, we still have a steady flow of interesting releases. Reanimated enabled its new layout engine by default. Shopify presented Helix, its internal tool to move away from RN. Xcode project format is finally moving to JSON! We asked on π: do average devs still care about React?Thanks...
