This week brings a collection of smaller, yet still noteworthy, React releases and articles.
On the React Native side, v0.85 just dropped with a new Shared Animation backend. Speaking of animations, we have a little sneak peek of exciting things coming, such as and Skia Graphite.
With the recent surge in npm supply chain attacks, itβs worth reviewing the npm Security Best Practices guide to secure your setup.
Let's dive in!
As always, thanks for supporting us on your favorite platform:
Notion, Dropbox and LaunchDarkly have found a new testing paradigm - and they can't imagine working without it. Built by ex-Palantir engineers, Meticulous autonomously creates a continuously evolving suite of E2E UI tests that delivers near-exhaustive coverage with zero developer effort - impossible to deliver by any other means.
Instead of manually creating skeleton screens for loading states, this innovative library snapshots your real UI at various breakpoints and captures skeleton "bones" - positioned, sized rectangles that mirror the layout exactly. It supports React, React Native, and other frameworks.

π Under the hood of MDN's new frontend - MDN launched a new frontend, replacing their old and difficult-to-maintain React CRA app for a new stack. They implemented their own Server Components system on top of Lit and Custom Elements, using Declarative Shadow DOM as a progressive enhancement.
π Moving Railway's Frontend Off Next.js - Feedback on migrating a Page Router app with 200+ routes to TanStack Start in 2 PRs with zero downtime. Their app now builds faster, has a more explicit model, and layout composition is easier.
π¦ Ink 7.0 - React renderer for CLIs - Unsurprisingly, this package has become quite popular with the rise of AI and terminal apps. This major version upgrades to Node 22, React 19.2, and adds many new hooks, features, and props.
15x faster TypeScript and JavaScript debugging than with breakpoints and console.log, while upgrading your AI agent into an expert debugger with real-time context.
Wallaby.js runs your tests as you type, feeding your AI assistant live runtime values, code coverage, error details, and execution paths β all right next to your code. With Wallaby v3βs new engine π, tests start instantly with cached results, prioritize active files, and stream updates in real time.
Built for testing, Wallaby includes a Time Travel Debugger, the ability to run only opened files, full-context AI integration, smart test runs, and more.
React Native 0.85 notably ships with a new Shared Animation Backend built in collaboration with Software Mansion, alongside a few other improvements and breaking changes:
Shared Animation Backend: This new internal engine will soon be enabled in React Native 0.85.1 and power both Animated and Reanimated. It enables performance benefits for Reanimated, and the core Animated API will finally animate layout props through the native driver!
DevTools Improvements: Multiple simultaneous CDP connections allow you to debug with DevTools, VS Code, and AI agents simultaneously without sessions dropping.
Metro TLS Support: HTTPS and WSS during development for testing secure APIs.
Breaking Changes: Jest preset moved to @react-native/jest-preset, dropped EOL Node versions, and removed StyleSheet.absoluteFillObject.
π¦ RN Windows 0.82 - Fabric-only, XAML UI Hosting - Community modules can now embed native XAML controls directly in Fabric. New accessibility override API gives third-party modules fine-grained control over screen reader behavior.
π JSIR - A High-Level IR for JavaScript (RFC) - Google's new JavaScript IR (Intermediate Representation) proposal for static analysis. Already used internally for code analysis and deobfuscation, notably decompiling Hermes bytecode.
