Go check out my very first blog post! 🤓✨

What if your #ReactNative app could start fetching data already before the JS bundle starts running? 🤔
We migrated @expensify's app to 𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚝𝚒𝚟𝚎-𝚗𝚒𝚝𝚛𝚘-𝚏𝚎𝚝𝚌𝚑 and moved its critical startup request ahead of JS - the result: Up to 950ms faster TTI! ⚡️
Across all daily active users, this saves more than 21 hours a day of loading time! 😎

I just released nitro fetch 1.9.0 . This has lots of bug fixes and performance fixes.
1. iOS websockets are rewritten on top of `Network.framework` which results in 30% faster response time on some messages. You can still fallback to old behaviour

2. Nitro fetch now supports in built SSL pinning .

I recreated Minecraft with Claude, entirely in C.

60+ FPS on a 1.2 GHz dual-core CPU. No dedicated GPU.

Announcing Apex: agentic coding model for mobile and web, specialized in React.

We built Apex from a single idea: can an open-weight model deliver frontier-level performance at lower cost?

Yes. Apex is SOTA in React Native and Next.js.

I made expo-native-variants, an Expo config plugin 👀

It sets up Xcode schemes and Android Studio flavors. Prebuild your app once per native change, then build dev, preview or prod without running it again.

Separate app IDs, names, URL schemes and icons.
