Discord Dropping Electron and React Native for a Rust Rewrite — Discord, one of React Native's best-known users, is moving away, with its CTO 𝕏 showing off a Rust desktop client built on GPUI using 290MB of RAM, with mobile keeping native UI over Rust code shared with the desktop client.

Tom Warren (The Verge)

▶️ Just prior to this reveal, Software Mansion interviewed Discord's Chas Jhin about how React Native development works at Discord's scale, in the ominously titled 'Maybe React Native Is Impossible'.

A Roadmap for Redux Toolkit v2.x and 3.0 — Mark Erikson has laid out the roadmap for Redux (complete with a neat history lesson) with RTK 3.0 expected in six to eight months, going ESM-only with 'React 19-scale' breaking changes. But a run of 2.x releases will ship the groundwork first, starting with 2.14 this week.

Mark Erikson

IN BRIEF:

⚠️ Update to Next.js 16.4.5 or 15.5.29, as appropriate: the November security release fixes seven advisories. Most are Cache Components bugs, so the post is worth reading.
🤖 TanStack Query maintainer Dominik Dorfmeister says work on Query v6 can start once 'slop PRs' stop coming in and taking up his time, leading to a thread on the effects of AI-made contributions on maintainers.
Vercel is folding Next.js's Data Cache into Runtime Cache with bigger allocations but… new per-read and per-write pricing. Hobby teams migrate on November 29, but check the dates and prices for your use case.
Vercel builds also now block known-malicious npm package versions before and during install, on all plans and with no configuration needed.

Next.js is Prototyping Go(lang) Route Handlers — A merged experimental PR lets an App Router route be a route.go file exporting GET and friends, compiled by Turbopack and run in supervised Go-powered workers. Tim says Rust could follow along the same path.

TanStack's smaller React for the browser

Putting MUI, Mantine, Ant Design
and React Spectrum Under Load

Den Odell wanted to see how popular design systems cope when you give them real work, so he timed ten of them, including MUI, Mantine, Ant Design and React Spectrum, and profiled the slowest cases. "Performance belongs on the design system team's priority list, next to accessibility," he says. Some highlights:

📊 With the CPU slowed 4x, opening a 249-country dropdown took 84ms in Mantine and 134ms in Ant Design, but over 200ms in MUI and React Spectrum, both of which froze the UI past his 100ms budget.
🔍 React Spectrum's problem was React Aria measuring options one at a time and forcing layout for each. Den filed an issue and a fix is in review.
⚖️ Framework alone didn't decide the results as non-React Ionic was by far the slowest to open (1,266ms) yet was quick at checking 100 checkboxes, while MUI handled them in 70ms compared to Ant Design's 421ms.
🧪 Want to try this on your own components? Den's Playwright tests are available on GitHub.

💬 Does Redact pay off? On r/reactjs, commenters pondered who needs it and how it differs from Preact, while one tester found re-renders cost about twice the CPU across two production sites.

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.

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>.
