React Compiler in Rust rollout

The integration has finally started to land in mainstream libs, starting with Oxlint, but may others are following:

• 📦 Oxlint 1.70 - Add a react/react-compiler rule - This experimental rule leverages the Rust port of the React Compiler and surfaces the same diagnostics as eslint-plugin-react-compiler. Early adopters (React Spectrum, Sanity) have already reported significant (x5-6) performance improvements.
• 👀 Rolldown PR - Expose React Compiler options - PR already merged, so Vite and Rolldown users will soon be able to use the transform.reactCompiler option.
• 👀 SWC PR - Add React Compiler - The PR has been merged and released in Rust crate v68.1, exposing a new jsc.transform.reactCompiler configuration option.
• 👀 Rspack PR - Bump SWC to support the React Compiler - In the next v2.1 release (the beta drops tomorrow), builtin:swc-loader will support the React Compiler in Rust. The Rspack team reported that the Rust version is 7-13x faster than the Babel one (tweet).
• 👀 Next.js PR - Add experimental Turbopack React Compiler support - This adds a new experimental.turbopackRustReactCompiler option. Available in Next.js v16.3.0-canary.52, and likely to be released very soon in Next.js 16.4.

• 💸 Product for Engineers - The stuff nobody tells you about startup marketing
• 👀 HTML proposal - Localized time formatting without JavaScript - Have you ever come across date-related SSR/SSG hydration errors in React or any other framework? Apparently, browser vendors agree that these problems need to be solved, and here’s an initial proposal based on declarative HTML attributes.
• 👀 WordPress - React 19 upgrade temporarily reverted in Gutenberg - WordPress initially announced a React 19 upgrade for the Gutenberg plugin and WordPress. They encountered JSX runtime compatibility issues between React v18/v19 and had to revert. Support for v19 is still planned for WordPress 7.1.
• 📜 Rethinking TSRX - The TSRX (TypeScript Render Extensions) syntax has been redesigned to be backward-compatible with JSX, easing its adoption and making its proprietary features more explicit. An interesting project to watch this year, coming from Dominic Gannaway (React, Svelte, Inferno), offering an ergonomic shared UI syntax compatible with various framework runtimes.
• 📜 TanStack Start: A Mental Model for Next.js Developers - A deep dive into the differences, covering typesafety, isomorphic loaders, RSC-as-data mental model, and more.
• 📜 Module System Dependency Injection in React & Friends - An interesting overview of Dependency Injection across React meta-frameworks, and a critique of Next.js suggestion to use the module system for DI in RSCs.
• 📜 Building an LLM safe design system - Polar’s new design system relies on a single polymorphic <Box> component with typesafe props accepting StyleX design tokens. They forbid the usage of Tailwind or primitive HTML elements, so that AI agents always respect their design decisions.
• 💸 Certificates.dev: Free React Weekend. Unlimited access to 9 chapters, 49 quiz questions, 13 coding challenges, and a trial exam. 27-28 June
• 📦 Hydrogen developer preview - Shopify’s framework, initially leaning on Remix/React, is becoming a framework/runtime agnostic toolkit, designed in partnership with the Next.js team.

Make your logs queryable, not just readable

console.log("here")doesn't cut it in production. Structured logs do.

Use this tutorial to connect LogTape + Sentry and make every log searchable, queryable, and connected to your traces. When something breaks, you'll get the full picture: log events, error context, and Session Replay, all linked by trace ID.

• Filter by user ID, order ID, or any custom field
• Attach context once, inherit it everywhere
• Alert when log patterns spike before users notice

This week, we’re taking a look at the new React Foundation website, as the React core repositories transition to their new home. All eyes on the React Compiler in Rust, coming soon in your everyday toolchain.

React Native 0.86 is almost here, but releases apparently like to land on Wednesday evenings 😅 so we’ll cover it next week. Let’s focus on React Native Runtimes instead, a quite interesting multi-threading innovation.

Cloudflare has acquired VoidZero, and npm v12 will officially block postinstall scripts by default in July, improving our supply chain security.

⚛️ React​

The React.Foundation website

The React Foundation was announced nearly a year ago, and you may be wondering what actions it has taken so far. Did you know the React Foundation had a website? Although it’s still a work-in-progress (source code), it’s already up and running and worth taking a look at to discover what’s planned, such as:

• A system to fund maintainers of critical ecosystem libraries
• An official React merchandise store with profits redistributed to maintainers
• Quarterly transparent reports with revenue details, maintainer funding, and more
• A logged-in “Contributor Status” page, adding a cool gamification layer

Earlier today, most React-related repositories also moved from the facebook GitHub organization to the react GitHub organization, reflecting the transition to the React Foundation. This includes React, React Native, Yoga, JSX, Metro, React-Strict-DOM, Create-React-App, and more.

It’s not facebook/react anymore, but react/react: end of an era!

React Native Runtimes

Margelo, in collaboration with Callstack, introduced a new package to add a multi-runtime layer to React Native apps. It’s a great solution for performance-heavy features and business logic isolation to avoid blocking interaction.

If your app has features that jank on mount, slow first-open screens, background hydration or decoding, state logic competing with animation, it might be worth checking it out.

Key features:

• Run selected components, screens, and headless tasks.
• Share state across runtimes through a native Zustand-style C++ singleton.
• Prewarm runtimes to avoid cold-start lag.
• Call a typed function on a specific runtime and await the result.
• Expo support with a config plugin.

• 💸 Product for Engineers - The golden rules of agent-first product engineering
• 👀 React Native RFC - Android Gradle Plugin v9 adoption - This drafts a three-phase AGP v9 adoption strategy to keep up with Android, doing the required changes to support built-in Kotlin before the opt-outs are removed in AGP v10.
• 👀 Static Hermes - What's new in the next stable release - This blog post announces many new ES features to be supported natively, including Set operations, Iterator helpers, groupBy, TextDecoder, and more. It will also be faster and support built-in TypeScript type-stripping!
• 👀 Standard Navigation integration PRs - Remember Expo Router 56 forking React Navigation? Fortunately, we have a shared abstraction for creating navigators that can work with both routing libraries, and should help reduce ecosystem fragmentation. It has already been integrated into React Navigation (PR) and Expo Router (PR).

See ya! 👋

This week we have great deep dive blog posts about data fetching (TanStack vs Next.js) and performance (GitHub and Linear).

On the React Native side, Expo dropped a major SDK with Expo UI stable. Reanimated leverages the shared animation backend and improves CSS animations on iOS.

Supply chain security remains an important topic. npm introduced staged publishing workflows, and will block postinstall scripts by default in the near future.

Let's dive in!

Ship AI generated code safely with Meticulous.

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.

Fortunately, top AI-driven teams like Dropbox, Notion, LaunchDarkly, and Wiz rely on Meticulous to run 1000s of e2e UI tests autonomously, covering every user flow, edge case, role and permutation. Built by ex-Palantir engineers, Meticulous gives you near-exhaustive coverage in weeks, without any developer effort. 

It works like magic in the background:

• Near-exhaustive coverage on every test run
• No test creation
• No maintenance (seriously)
• Zero flakes (built on a deterministic browser)

Check it out - and see why one engineering leader at Dropbox said that “once we started using Meticulous, we couldn’t imagine working without it.”

• 📜 Component Architecture for React Server Components - A deep dive into data fetching techniques, their limits and tradeoffs. RSCs permit to design explicit loading experiences and leverage composition more than loaders.
• 📜 TanStack Router and Query - Integrating Query with Route loaders permits to start fetching data as early as possible (even on intent / link hover), and have granular control over what suspends/defers. It’s recommended to avoid Router.useLoaderData() and treat the loader as a fire-and-forget event handler.

Expo SDK 56

A new Expo SDK is out! As always it’s packed with lots of changes. It bumps to React Native 0.85 and React 19.2, which bring Hermes V1 by default, the new animation backend, and more.

Here are the most notable highlights:

• Stable Expo UI - SwiftUI on iOS and Jetpack Compose on Android, now production-ready, providing universal components, replacing 8 community libraries. The worklet integration and useNativeState() help you implement flicker-free <TextInput> masking.
• Expo Router - no longer depends on @react-navigation/*. It ships with experimental support for the new native stack (Material-style headers, predictive back gesture), SSR streaming on web, and customizable SuspenseFallback in layout routes.
• Faster native builds - precompiled XCFrameworks cut iOS clean builds ~16% and opt-in precompiled headers on Android deliver up to 2.81x faster CMake builds.
• Expo modules improvements - inline modules let you write Kotlin/Swift alongside JS with automatic TS type generation. A new Kotlin compiler plugin replaces reflection, yielding ~40% faster cold starts and ~33% faster first render on Android.

And many more great additions like File System API, consistent status and navigation bars, and stable iOS widgets, there are far too many updates to list. Make sure to check out the full changelog or watch the official intro video.

• 💸 PostHog - 4,063 errors closed without a human opening PostHog – here's what we learned
• 👀 React Navigation PR - Rework server rendering API to support streaming
• 👀 React Strict DOM PR - Adopt React Native 0.82 DOM Node APIs
• 💬 React Native RFC - Dedicated *Instance types for built-in RN component refs - With the upcoming Strict TypeScript API and auto-generated types, built-in components will be typed as functions instead of classes: useRef<View> will break. This RFC proposes to export a ViewInstance type to let you type useRef<ViewInstance> instead.
• 📜 The Go-To Guide for Understanding Keyboards in React Native - A deep dive into how keyboards work, differences between OS versions, quirks, and how to make it work across platforms.
• 📜 Profile React Components in React Native Release Builds - A way to profile without debug-mode overhead similar to what web developers do for a long time.
• 📜 One React for Web and Native - An outline on how to unify React Native with the web platform to reduce ecosystem fragmentation. React Native directly implements subsets of the DOM specification to make React Strict DOM possible.
• 📦 NativeScript React Native - TurboModule wrapper giving access to all native APIs in React Native, letting you create UIKit views on the fly. This looks promising, and I’m sure we’ll hear more about it soon!
• 📦 Lynx UI - The React Native competitor launched unstyled UI components for ReactLynx covering scroll views, popovers, swipers, sheets, reference design language. Programmable interactions and motion.
• 📦 Reanimated 4.4 - iOS CSS Core Animation engine, Animation Backend, useTimestamp hook, precompiled headers on Android - Add supports for RN 0.85 new shared animations backend, behind a flag.

See ya! 👋

It looks like security is going to be a hot topic this year! 😅
More packages are being compromised, and blog posts are also covering recent RSC vulnerabilities.
Maybe we’re reaching a tipping point, and better security practices will consolidate this year.

On the React Native side, Hermes-node is quite exciting, although it’s very early.

An exciting TC39 meeting is currently underway, and several proposals have already progressed.
Yarn and npm are improving on the security side.
Bun and pnpm are being ported to Rust.

Mini Shai-Hulud worm keeps digging

Remember last week’s TanStack Router compromise? The dangerous worm from TeamPCP keeps compromising users and maintainers across ecosystems, affecting popular packages such as echarts-for-react and @antv, and GitHub actions such as actions-cool/issues-helper. OpenAI employees got compromised, leading them to regenerate code signing certificates. Grafana has been blackmailed by a ransomware group.The Million.js repository was also briefly compromised, but they seem to have gotten lucky: it apparently didn’t affect anyone.

Rumors also link this worm to the Nx Console VSCode extension compromise, and possibly connected to a major GitHub internal repo breach. This story isn’t over — “Mini” feels like a very questionable name 😅!
