This week we have an interesting React challenger, keeping its mental model but compiled ahead of time. Also various major announcements from the TanStack side.
On the mobile side, we have interesting RN 0.87 PRs to look at, discussions around workers / worklets, a WebGPU/Skia integration, and React Navigation 8 / Screens 5 progress.
Last week, many proposals progressed during a TC39 meeting. npm is going to scan for malware at publish time. Core Web Vitals will now measure SPA soft navigation.
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.
Dominic Gannaway β former React/Svelte team member, creator of Inferno β unveiled his new project, Octane, as a successor to Inferno.
It keeps Reactβs programming model, but compiles Hooks, Suspense, and Actions ahead of time. It improves performance, removing the Virtual DOM and using native browser events. You donβt need to respect the rules of hooks or to maintain dependency arrays manually. You can use it with JSX/TSX, but it also supports TSRX to improve your developer experience.
This looks like a quite serious React challenger using the same mental model, already receiving contributions from maintainers of popular project. It comes from day 1 with integrations for libraries such as TanStack, React Three Fiber, Lynx, StyleX, NativeScript, and more.
π Next.js docs preview - Offline support - With experimental.useOffline enabled, Next.js will no longer throw when the network is down, keeping requests pending with a retry.
ποΈ React Advanced London - π¬π§ London - 23 & 26 Oct. First speakers announced: TanStack Maintainer, Engineer at Vercel, Apollo TypeScript Client maintainer & more. All in a historic ex-brewery. Get 10% off with code "TWIR".
π TanStack - We Stopped Using RSC onTanStack.com - Tanner explains why the TanStack website adopted RSC in the first place, keeping heavy dependencies like the Shiki syntax highlighter on the server. But the maths change if the heavy libraries become smaller: itβs better to use SSR, ship a small lib once and render multiple times on the client than to render each blog post on the server and ship an RSC/Flight payload. To achieve better performance with SSR, TanStack had to introduce 2 new deliberately small projects: TanStack Markdown and TanStack Highlight, available in alpha. In TanStack Start, you can freely decide to use SSR or RSC when it makes sense.
π Making Referential Stability a Type - A really cool idea to tag memoized values directly in the type system with Stable. With stableref/react, you can enforce APIs to use memoized values and get compilation errors if props or dependency array elements are not memoized.
π How to Think in Remix UI Instead of React - A pragmatic intro to Remix v3 from a React perspective. Components run once, return a render closure, and you re-render with this.update(). This gives you more control than React hooks, but requires more boilerplate.
π The Absolute State of Management - Alex Russel argues React's state management libs don't manage state; they only propagate it with pub/sub. Real state management needs time and ordering: CRDTs, sync engines, vector clocks.
Hardcoded forms create a costly cycle: every new field, workflow, validation rule or customer-specific variation becomes another development task, code review and deployment.
SurveyJS breaks that cycle. Developers embed a JSON-powered form builder and reusable form runtime into their React application once. Business teams can then create and update forms through configuration rather than application code.
Ship new forms faster
Reduce repetitive frontend work
Launch form changes without waiting for a release cycle
Keep full control over your backend, data, security, and branding
Your developers own the platform. Your business teams manage the forms. π
π¬ React Native RFC - CSS calc() in React Native - A proposal to add a C++ implementation, so host platforms do not need to be aware of its existence. Aligns more closely with the web, avoiding onLayout and useless render passes.
π From Expo Router to Detour: Deferred deep linking the right way - Standard deep links break at the store boundary, causing an Installation Gap when the app is not installed yet. The solution is to use deferred deep linking to capture user intent and replay it on the appβs first launch.
π¦ RN Workers 1.0 Alpha - Separate Hermes runtimes created on a dedicated thread to enable real multithreading. Each worker has its own bundle. Communication between them is using messages via a structured-clone codec. This discussion explain differences with Worklets. Hermes also supports WebWorkers out of the box (unstable) that will be in a public release soon.
π¦ React Native WebGPU 0.7 - importDevice() - This lets you import the RN Skia Graphite WebGPU device. Itβs the foundation for zero-copy interop between the two worlds, letting you use WebGPU textures in Skia efficiently.
ποΈ RNR 368 - RNR Explains: Fabric - A look into how the Fabric renderer works. How it speeds up mobile apps and unlocks concurrent React features.
π£ Core Web Vitals - Measuring soft navigations - Measuring SPA soft navigations (page transitions with history.pushState) will be enabled by default in Chrome 151, and integrated into DevTools, the web-vitals package, Lighthouse, PageSpeed Insights, and Real User Monitoring tools.
π Your SPA Is Leaking Memory. Soak Test It - A practical Playwright recipe to catch SPA memory leaks. Loop a user flow, read Chrome's node/listener counts before and after, assert.
π Read Online Hi everyone, Seb and Jan here! Back after a little break to cover news from the last two weeks. A lot is going on, apparently not everyone is on holiday because we still have many interesting releases, including many RCs from upcoming major versions. The native React Compiler rollout continues. React v19.3 seems around the corner. Plenty of TanStack Router/Start and Next.js content. React Native 0.87 is now out, paving the way for v1.0. ποΈ Weβll be taking another break next...
π Read Online Hi everyone, Kasia and Kuba from Software Mansion here. This week, Next.js 16.3 officially shipped, bringing Instant Navigations to the App Router and cutting dev server RAM usage by up to 90%. On the React Native side, a new, faster PlainText component and a deep dive into Vision Camera v5. Across the broader dev ecosystem, GitHub stacked PRs finally entered public preview with native base retargeting and a gh-stack CLI. Let's dive in! ποΈFYI: weβre taking a break next week; see...
π Read Online Hi everyone, Seb and Jan here π! This week we have React and Next.js security patches. React Aria becomes first-class in shadcn. A benchmark grades coding agents at real React tasks. The rise of TSRX and its upcoming framework. On the mobile side, Swift Package Manager support is finally coming. A TC39 meeting is in progress; we'll share the proposal updates next week. Oxlint type-aware linting is ready for prime-time. Meanwhile, Yuku explains how it outperforms Oxc at parsing...
