Don't leak your implementation details. 🧠
@tkdodo.eu (the Query Sensei) has a new guide on Query Abstractions. Learn how to wrap TanStack Query to keep your UI clean and your data layer maintainable.
The "New Architecture" era is officially standard. 🚀
@expo.dev SDK 55 is now out of beta.
• Fabric/TurboModules by default
• 75% smaller OTA updates (bytecode diffing)
• Massive stability improvements
If you haven't upgraded yet, 2026 is the year to do it.
@cloudflare.social is coming for the @nextjs.org crown. ⚔️
They just launched ViNext, a specialized runtime to make Next.js scream on the edge. Meanwhile, @vercel.com fired back with a "Cloudflare to Vercel" migration guide.
Competition is a win for developers. Pick your side.
Your React skills just went 3D. 🥽
@reactnative.dev has officially come to Meta Quest. You can now build immersive VR/AR experiences using the patterns you already know. The bridge between 2D mobile and spatial computing just got a lot shorter.
@react.dev is moving to a neutral, non-profit home. 🏛️
The React Foundation (under the Linux Foundation) ensures that React belongs to the community, not just Meta. This is about long-term sustainability and open governance for the next decade.
React Weekly Issue #9 is HERE—and it’s a landmark one. ⚛️
🧵 The breakdown:
🏗️ The React Foundation is born
🥽 React Native x Meta Quest
☁️ @cloudflare.social ViNext vs. @vercel.com
🚀 @expo.dev SDK 55 (Stable!)
🧠 @tkdodo.eu on Query Abstractions
The best developers don't just write code; they build systems that scale.
Join the 35+ engineers who spend their Sunday morning getting a leg up on the competition.

React Native "New Architecture" users, rejoice. 🛡️
@sentry.io 8.0.0 is officially out. It brings full support for Fabric, improved symbolication for New Arch builds, and a smaller SDK footprint.
Don't fly blind on the new architecture—upgrade your observability today.
The @tanstack.com family just got a new member: Hotkeys. ⌨️
It’s a headless, type-safe library for managing keyboard shortcuts. It handles platform modifiers (Cmd vs. Ctrl) and complex combinations perfectly.
Your power users will thank you.
Is your React code feeling a bit... sluggish? 🏥
@aidenybai.bsky.social (creator of Million.js) just launched React Doctor. It’s a CLI tool that scans your project, finds performance "sickness," and gives you an actionable prescription to get back to 60fps.
No more profiling in the dark.
Over-the-Air (OTA) updates are a superpower—if you have a strategy. ⚡️
@expo.dev just dropped the definitive "Production Playbook" for OTA. We also dive into how OneSpot automates deployments for 200+ apps without ever touching a laptop.
Say goodbye to manual "laptop-deploys".
React Weekly Issue #8 is officially LIVE! ⚛️
🧵 The highlights:
🚀 The Production OTA Playbook
🤖 Automating 200+ App Deploys
🏥 React Doctor: Diagnostics for your code
⌨️ @tanstack.com Hotkeys
🛡️ @sentry.io 8.0 (Fabric Support)

Technical deep-dive: Why does the React Compiler hate Class objects? 🧠
We explore why OOP-style data structures break memoization and how to refactor for a "compiler-friendly" codebase.
Plus: 🛡️ Bulletproof components by @shud.in 🛣️ Type-safe Auth with @tanstack.com Router
Stop building dashboards from scratch. 🧱
@shadcn.com just released "Blocks"—fully composed UI sections (Dashboards, Auth flows, etc.) that are ready to copy-paste.
Combine that with @expo.dev ’s new guide on building AI-first photo apps using the CoreViz SDK.
React Native 0.84 has landed. 🚀
The theme? Stability for the New Architecture. We’re getting refined Fabric debugging, improved error boundaries for concurrent rendering, and faster Android startup.
The "New Arch" is no longer the future—it's the present.
The State of React 2025 results are a reality check. 📈
RSC adoption has moved from "experimental" to "standard." React Router 7 and the React Compiler are seeing massive jumps in sentiment and usage.
Check the full report to see where your stack stands in the ecosystem.

Want to build "High-Quality" mobile UIs without the Figma-to-code headache? 🎨
The Expo team shared a deep dive into building with NativeWind. Learn how to use Tailwind-style variables for theming and Reanimated for that premium feel.
Vercel is making the web "AI-Ready." 🤖
Instead of agents scraping messy HTML, why not just serve them clean Markdown?
By using HTTP Content Negotiation (the Accept header), you can serve 99% smaller payloads to AI agents while humans still get the full UI.
End of an era: ESLint v10.0.0 has arrived. 🛑
The legacy .eslintrc system is officially dead—it’s all about Flat Config now. v10 also drops support for older Node.js versions and introduces smarter JSX reference tracking.
It’s time to migrate those configs.
React Native developers, your gestures just got a massive upgrade. ✌️
Gesture Handler 3.0 is out with a completely new hook-based API. It’s fully compatible with the React Compiler and integrates deeper with Reanimated via SharedValues.
Say goodbye to unnecessary re-renders.
React Weekly Issue #6 is officially LIVE! ⚛️
This week is all about the "Next Generation." We’ve got major v10 releases, hook-based gesture rewrites, and a new way to serve your site to AI agents.

Building for mobile in 2026? 📱
The team at @expo.dev just dropped a masterclass on retention. From using OTA updates to "save" your App Store rating to leveraging behavioral push notifications—it's a goldmine for mobile devs looking to scale.
How do you get an AI agent to be 100% accurate? 🤖
@vercel.com just proved that "Skills" (tool-calling) aren't enough. By moving to a persistent AGENTS.md file in your root directory, AI coding accuracy jumped from 53% to 100% in their evals.
Context is king. Manual tool-calling is dead.
Stop what you’re doing and check your versions. 🛠️
A high-severity Denial of Service (DoS) vulnerability (CVE-2026-23864) has been found in the RSC 'Flight' protocol. It can trigger CPU/memory exhaustion with a single crafted request.
Whether you're on Next.js or Vite, you need to patch. Now.
Issue #5 of React Weekly is LIVE! ⚛️
This one is a "Must Read" for anyone in production. We're covering a high-severity security flaw in React Server Components and a game-changing AI breakthrough.
