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.

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.

• Expo Channel Surfing lets you switch OTA update channels (like a "preview" stream) at runtime on a production build. No reinstall needed. QA teams, rejoice.

How does @vercel.com make Turbopack so fast? It’s not just Rust—it’s Incremental Computation. 💨
By caching at the function level and only building exactly what changes, they've hit 10x faster Fast Refresh.

Native Bottom Tabs are finally the default. 📍
@reactnavigation.bsky.social 8.0 Alpha just dropped. It moves away from JS-mimicry and uses true native primitives via react-native-screens.
Smoother "liquid glass" effects and a revamped type inference system.

The "Legacy Architecture" is officially history. 🪦
@expo.dev SDK 55 Beta is out, and it’s New Architecture only. No more toggles.
Plus:
• Hermes v1 opt-in
• Bytecode diffing (OTA updates 75% smaller!)
• A new /src project structure
The mobile DX bar just got raised.

Attention: Patch your Node.js servers immediately. 🛠️
A bug in AsyncLocalStorage was causing stack overflows to bypass error handlers and take down production servers—affecting virtually every Next.js and RSC app.
The patch is live. Don't let your server go "dead."

Is useOptimistic the silver bullet we hoped for? 🧐
Colum Kelly argues that while it’s a great first-class citizen in React 19, it doesn't magically solve race conditions or transition complexity.
A must-read for anyone building high-fidelity UIs.
