What a day to be a React Native dev

React Native Reanimated 4 is now stable and ready for production 🐎 Featuring CSS Animations & Transitions, multithreading with React Native Worklets and more.

I’ve been using React Native for ~5 months now, after 4 years of professional development with Flutter and 2 with Swift. Still amazed how often I find that @expo and the community have already thought about so much things to improve quality of life. Feels like magic,…

React Native doesn't get enough praise for what it did for mobile. Spent 12 years doing Android natively at scale and I doubt I will need to touch that kinda code any time soon due to the advantages of using Expo/React Native. May contribute some fixes to Expo Android issues

Still a work in progress for a customer - lots of little things to refine and colors are not nailed yet. But it's coming along, and the feel is really smooth 🚀 Built with @expo SDK53 and of course expo-router (loving the new Protected Routes approach!), API routes, plus…

Say hello to auth flows without redirects! 💜

🆕Expo Router’s new protected routes offer a cleaner, more declarative way to manage access in your navigation structure. By using `Stack.Protected` and `Tabs.Protected` directly in your layout files, you can: ◆ Define auth flows clearly and predictably ◆ Avoid imperative…

Today, @OpenAI launched their Agents SDK developer framework. Until now, agents have mostly been chat-oriented (chat in, chat out), but agents will increasingly be action-oriented (data in, action out). We, @stripe, would love to show you a few financial agents we’ve built! ⤵️

We've been actively exploring AI on mobile devices & we are excited to introduce React Native ExecuTorch 🚀! A new library that enables the execution of AI models with just a few lines of JavaScript, without the need for API calls or external infrastructure. 🤩 More in 🧵👇

We've just finished migrating the @Shopify mobile app to @reactnative 🎉. This is our biggest app and was built over a decade. Here's how it went 🧵

Does anybody else feel like the React Native ecosystem is firing on all cylinders right now? This is incredible.

Finally got something to show - we're working on a new 3D library for React Native! 👀🧊 👉 Powered by native Graphics APIs (Metal/Vulkan) 👉 Full control over rendering in JS 👉 120 FPS rendering on a Worklet Thread (no lags!) 👉 Supports hotswapping .glb/.gltf models

Can't believe it. I've been trying to bring seamless native API access to React Native for 5+ years, and just tackled the final boss. We just called an arbitrary UIKit API from JS, on the UI thread, with no native code – thanks to NativeScript, Node-API, and Reanimated. 🥹🚀

Not much content can be found online on how SpaceX/Starlink uses React Native and Expo. Really appreciate @aarongrider taking the time and making the effort to share a bit about that. Looking forward to his talk at @appjsconf

Stoked for this!

💡 With Microsoft AppCenter retiring, here are a few things you should know about @Expo App Services: ◆ EAS works with any React Native app, regardless of the CLI ◆ EAS Builds can be run locally for free ◆ EAS Submit is 100% free ◆ EAS Updates can be self-hosted

Video production on this one is next level. Worth watching just for that if you’re not interested in React Native much. But if you are than oh my… you’ll be stunned by the amount of innovation @wcandillon is putting out (consistently) with React Native Skia
