Expo

?? The imitable Jack ?? Herrington of youtube fame made a video about our React Server Component announcement and we're thrilled about it. In the vid he shows how you can drive your native UIs directly from the server using Expo and RSCs! Check it out: https://lnkd.in/g6zWjJG2

I?just vibe coded 5 apps using 6 different AI-powered tools—completely free! ?? Some were impressive, some… not so much. ?? Video dropping soon! Which AI coding tool do you trust the most? ??

?? Excellent new React Native crash course from the JavaScript Mastery team. In this course you'll learn how to build a full stack mobile movie app. And you'll see why Discord, Burgerking, Coinbase and other big companies build with Expo. https://lnkd.in/gJzxXsMi

If you don't love wrestling with native configurations in React Native you can just use Expo. We built Continuous Native Generation (CNG) to simplify all that... ?? No native folders in your repo ? Automatic native builds Learn more about how Expo makes life easier: https://lnkd.in/gXecacsU

?? Take a look at this beginner-friendly tutorial about how to build a Local-First React Native app with TinyBase and Cloudflare. In the vid, you’ll learn how to: ? Install and use TinyBase to manage simple todo records. ? Create and deploy a Durable Object to sync data seamlessly. This is an excellent way to begin your local first development journey. https://lnkd.in/gycBK8-Y

??? Do you treat testing as a tedious chore or a supportive friend? For React Native developers using Expo, a solid test harness can be the path not only to strong apps but also peace of mind. ?? Steve Galili sees testing as a safety net that catches bugs before your users do, allowing you to ship with confidence. He shares his whole philosophy in our latest blog post (link below). Check out some of the key takeaways: ? Testing Pyramid for Balance: Build a foundation of fast unit tests, add a layer of integration tests for modules working together, and cap it with a few E2E tests that simulate real user flows. This pyramid keeps your test suite fast, thorough, and reliable. ? Practical Expo Strategies: Leverage Jest and React Native Testing Library for component tests. Use tools like Maestro for end-to-end testing (yes, you can E2E test Expo apps!). Set up a dedicated Expo dev build or config for testing to mirror production behavior. ? Avoid Common Pitfalls: Don’t rely only on slow end-to-end tests or over-mock your app until tests lose meaning. Avoid flaky tests by cleaning up after each run (no shared state!). Ensure your tests are deterministic and reflect real usage as much as possible. ? Coverage vs. Real World: High coverage is nice, but meaningful coverage is crucial. Focus on critical user paths and edge cases. It’s better to have 80% coverage with robust tests than 100% coverage of trivial scenarios. Aim for quality, not just quantity. ? Confidence to Refactor: With a solid harness, you can refactor or add features without fear. Your tests will catch regressions early. That means faster iterations and happier users (and developers!). ?? Read the full blog for code snippets & detailed insights: https://lnkd.in/gWrTv7tD ??

Ever wondered what happens during an Expo pre-build? ??Gabriela from Theodo breaks it down for us here. https://lnkd.in/gAj9xQN7

?? The Bluesky Social app was originally built by one dev: Paul Frazee. He used Expo to build a prototype of an app and then the protoype became the production app! Paul joined the Ship It! podcast to talk about how Bluesky builds, tests, and deploys mobile and web applications from the same code base. https://lnkd.in/gA4K5iBF

?? Today our CTO, James Ide, shared our vision for Expo and AI Coding.

?? Leverage your React knowledge to ship a mobile app with these three tools... This is a brand new tutorial about how to build React Native apps in 2025. In this video you'll learn how to use Convex, Clerk.com, and Expo to ship a real-time social media app with 7 screens. https://lnkd.in/gffYqfG8
