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.

▶️ 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.

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.

Amazon's React Native-Based Vega OS Hits 2.0 — Vega, the React Native-based OS behind newer Fire TV devices, is out of beta. SDK 2.0 takes apps from RN 0.72 to 0.83, bringing the React Compiler and Hermes v1 into play. The release notes go into more detail than the post.

Skullet: Skeleton Loading States Measured from Your Components — Hand it sample data and it renders your real component invisibly, measures everything, and draws a matching skeleton to reduce layout shifts when data arrives. The docs have a neat How it Works section explaining the technique.

Parcel 3 Alpha: A Rust Rewrite with React Compiler, Tailwind and RSC — Parcel's core is now a Rust binary with no Node dependency, and the team reports cold builds up to 100x faster than v2. React Compiler (opt-in), Tailwind and MDX are built in, with RSC support in beta.

react-resizable-panels Gets a VS Code-Style Workspace Component — Brian Vaughn's popular panel library now does dockable tabs you can drag to split or merge panes, and moved tabs keep their state rather than remounting. There's a live demo here.

James Long has been reviving Prepack, Facebook's abandoned JavaScript partial evaluator. There's a React demo where a pretend site is server rendered three ways, by React, by Prepack's output (which essentially 'compiles' React away), and a hybrid, with the render times to compare.
Node.js 27 Alpha has landed, the first version using Node's new release process (where a release will spend six months in 'alpha' before going Current), while Node 26 is now the new LTS line.
Chrome 157 rolled out this week with HTML-in-Canvas now stable. It provides a way to draw real DOM elements into 2D, WebGL and WebGPU canvases. The demos are striking.
Vercel has released Geist Serif, a new serif font that shares metrics with Geist Sans so the two can mix cleanly. It's not on Google Fonts yet, but the geist npm package includes it.
