Next.js 16.3 Preview - Instant Navigations

Next.js 16.3 is now in preview and will be stabilized in the coming weeks. This sneak peek focuses on a new opt-in feature called Instant Navigations, improving on top of Cache Components. This addresses the loudest criticism of the App Router: server-driven navigations feel like clicking a website, not an app.

With this new feature, you will have to make a very explicit choice whenever you await some data on the server, nicely presented in an Instant Insights dev panel to surface slow navigations:

• Stream with <Suspense>
• Cache with ’use cache’
• Block with export const instant = false;

There’s more:

• Playwright instant() test helper - Assert what must be instantly visible after a link click.
• Partial Prefetching - Instead of prefetching a page per link in the viewport, Next.js will now prefetch a reusable shell per route. You can still prefetch links more aggressively (opt-in).

• 👀 ESLint Plugin React - ESLint v10 compatibility progress - React users of this ESLint plugin have been stuck on ESLint v9 for a while. Thankfully, v10 support has just been merged into the Import plugin, which should also unlock the React plugin compatibility.
• 👀 Vercel and Shopify are rebuilding Hydrogen - Vercel is helping Shopify improve its proprietary Hydrogen e-commerce framework. Initially based on React/Remix, the new version should be more portable, supporting Svelte, Nuxt, Next.js, and various server runtimes.
• 📜 Rolldown Pulls Rust React Compiler Integration After Binary Size Increase - Nicely summarize the tradeoffs of integrating Rust extensions in frontend tools, and whether it’s a good idea for a framework-agnostic tool to have a first-class integration with React. Oxc blocked the integration until it’s slimmed down (in progress), while Rspack chose to ship the Compiler now and optimize incrementally.
• 📜 React Compiler Is A Retrofit - Argues that, unlike Solid/Svelte, the React Compiler optimizes a runtime model that was not initially designed around a compiler. It can increase bundle size and make the memoization contract of your APIs less explicit. It is safer to use it as a linter rather than a compiler.
• 📜 Different hydration and rendering strategies - Explains how much JS runs between "looks ready" and "actually works", across every rendering strategy, including non-React ones.

• 📦 Astryx - Meta’s open-source design system, built on React and StyleX - Meta released an OSS beta version of their design system, built over 8 years and powering 13000+ internal apps, using StyleX atomic CSS-in-JS library. It’s not a headless lib, but highly themable with design tokens and the ability to eject the components to customize them entirely.
• 📦 Rspack 2.1 - React Compiler in Rust, TanStack Start support, perf improvements, TypeScript 7, import.meta.glob(), and more - Rspack now has a first-class integration with the React Compiler through SWC, reporting it being 7-13x faster than the Babel version. Also, TanStack Start now supports Rsbuild 2.1 through a plugin.
• 📦 shadcn/ui - Chat interface components, @shadcn/react - This Chat UI update also takes the opportunity to introduce a new package for unstyled, headless React components. For now, there’s only a single <MessageScroller> primitive, but more could come later?
• 📦 Storybook for TanStack React - A dedicated Storybook framework for TanStack-powered React apps. This provides first-class, type-safe support for TanStack Router, Start, and Query.

Expo SDK 57

It feels like Expo SDK 56 just got released, and we’re already on SDK 57, even skipping the beta phase!?

Since RN 0.86 got released with no breaking changes, the Expo team decided to cut the new release sooner than usual. It’s a test of a new release cadence that will follow RN releases more closely. React Native’s move towards stability should make it easier to offer the latest changes almost immediately. Why not do it as a part of the SDK 56 update, then? There are still many changes, and it’s better to make the upgrade intentional to avoid unexpected errors.

RN 0.86 features are now available in Expo: first-class edge-to-edge support on Android, light/dark mode emulation in React Native DevTools, and rendering, layout, and animation fixes. Expo 57 also comes with a list of various Expo-related improvements.

React Docs - <Fragment ref>

In an upcoming version of React, the ref prop will expose a new FragmentInstance type that lets you interact with the fragment first-level children, unlocking new composition patterns. This exciting feature has just been documented more exhaustively, including 5 example use cases to get inspired from.

This feature is already available in canary, has gone through extensive testing in production, and is likely scheduled for React v19.3.

Note that React Native will also get a similar feature (draft docs PR). I don’t know if React / React Native will have full feature parity, but it’s clear that this will enable cross-platform usage on at least a subset of these APIs.

• 💸 SVAR React Gantt Chart - Try React Gantt component for project scheduling with dependencies, critical path, and resource planning
• 👀 Bun PR - React Compiler integration - The upcoming Bun 1.4 should come with a bun build --react-compiler flag that runs the React Compiler in Rust, up to 20x faster than the Babel variant.
• 🐦 The React Compiler in Rust removed from Rolldown/Vite - The React Compiler in Rust needs to be integrated natively into Oxc to maximize performance, rather than shipped as a plugin. Unfortunately, this increased the binary size too much for all Rolldown/Vite users, so the integration has been temporarily withdrawn while it gets slimmed down.
• 📜 Moving Linear from styled‑components to StyleX - The Linear team has been looking to adopt an alternative to Styled Components (in maintenance mode). They settled on StyleX for its static extraction, minimal runtime, strong encapsulation, deterministic style resolution, ecosystem, developer and agent experience. They use an incremental migration strategy using AI and codemods.
• 📜 How an Underrated Refactor Saved 90% Memory Usage - TanStack Table v9 significantly reduced memory usage for large tables by migrating row object methods to shared prototypes.
• 📜 Waku’s Unique Feature: Slices - A short intro to Slices, a unique Waku feature inspired by Gatsby, easy to understand and yet quite powerful.
• 📜 How We Cut Slow Responses by 80% Migrating to Next.js App Router - The leading italian classifieds marketplace upgraded from the Pages Router to the App Router, using an incremental side-by-side strategy
• 📜 Component Communication Patterns in React Applications
• 💸 Sentry - Join Simon Grimm as he triages a real React Native crash live in production using replays, logs, and Seer
• 📦 React Router 8.0 - Turns v8 future flags on, ESM-only, upgrades React/Vite/Node min versions - This release is “boring” on purpose to make the upgrade easy. It essentially enabling by default behavior changes that were previously released as opt-in future flags in v7. React Server Components are still being worked on and unstable.
• 📦 cnfast - Fast drop in replacement for clsx + tailwind-merge - Tailwind users, maybe this hasn’t crossed your mind, but using tailwind-merge means you’ve added a quite slow runtime CSS-in-JS layer to your React app. This new project is a 4x faster alternative, although it remains a bottleneck.
• 📦 StyleX 0.19 - Inline atomic styles, ESLint 10 compatibility, expands shorthand autofixes
• 📦 Base UI 1.6 - OTPField stable, Drawer improvements, Combobox perf, docs redesign, many fixes
• 📦 Remotion 4.0.464 - Composable effects for canvas-based components
• 📦 React Aria 1.19 - Autocomplete @mentions, support Popover position relative to cursor
• 📦 React Hook Form 7.80 - useFieldArray({disabled}), perf improvements
• 📦 ForesightJS 4.0 - Predicts user intent based on mouse/keyboard inputs - First-class React integration
• 📦 PolyCSS - CSS 3D engine for the DOM, with React bindings

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

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.

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.”

⚛️ 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.

• 👀 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).
