You can now trigger EAS Workflows with a single HTTP request. New REST endpoint for workflows dispatch. POST your bearer token, app ID, and workflow YAML. Get back the run URL. No CLI. No login flow. Just wire Expo CI into your dashboard, your tool, or your platform.

SDK 56 beta is out 😅 ◆ 50%+ faster iOS builds ◆ 40% faster Android cold starts ◆ Expo UI + iOS widgets now stable ◆ expo-router rebuilt from scratch ◆ Inline native modules + brownfield multi-app support Strong "speed and stability" theme in this one: try.expo.dev/bluesky

Kiril Kostev built an AI video app and got it to both stores in ~1 month. He wrote up the async pipeline, file upload workarounds, polling patterns, and how EAS Build cut days off the timeline. Great read if you're building anything with async AI APIs on mobile: expo.dev/blog/how-to-...

Two devs. One codebase. A video social app users think came from a big team. Tendbble's writeup on how they solved video memory, 60fps on Android, and a camera leak hiding behind React Navigation. expo.dev/blog/shippin...

Update on Expo Go & the App Store: As of today a version of Expo Go for SDK 55 is still waiting for approval on the Apple App Store. We hope that we can release this update soon, but we can't provide a timeline. More context and suggested next steps are here: expo.dev/changelog/ex...

If your Android builds are taking a while to complete on EAS, try out the EAS_GRADLE_CACHE flag to save time on subsequent builds 🚀

🎤 Announcing: Charlie Cheever If you're in tech, you know @ccheever.com Charlie's the co-founder of @expo.dev and one of the biggest driving forces behind React Native!! Charlie's joining us live in Portland for Chain React. 🎟️ ti.to/chainreact/c...

Android builds on EAS are now ~50% faster with Gradle caching. Task outputs get stored and reused between builds. Especially effective for projects with many native modules, where the same tasks repeat across each one. Enable with 𝙴𝙰𝚂_𝙶𝚁𝙰𝙳𝙻𝙴_𝙲𝙰𝙲𝙷𝙴=𝟷 expo.dev/changelog/gr...

When does your React Native animation library actually matter? @appandflow.com benchmarked per-frame UI thread cost across react-native-ease, Reanimated (Shared Values and CSS), and RN Animated. Honest tradeoffs, real numbers, and clear guidance on when it matters. expo.dev/blog/the-rea...

if you're in or near prague, check out the @expo.dev x STRV hackathon this friday (may 1)! 💡 the idea: pick a business that you care about that either doesn't have an app or whose app desperately needs to be replaced, then build the best app you can in a day.

You can now sign into Expo with @github.com. Those of you who have Expo's GH app authorized/installed probably got this email from GitHub. It's very legit. Go ahead and approve the permissions request if you'd like to to sign in with GH (or ignore the email if you aren't interested).

🇹🇷 When FERASET started in late 2022, most mobile engineers in Turkey thought Expo was a prototyping tool. Something for a demo or a hackathon, not production. FERASET saw Expo differently. They went all in...and all the way to #1 on the app store. Here is their story: expo.dev/blog/from-is...

Hipcamp upgraded to React Native New Architecture + Expo SDK 54 in 2 weeks. Original estimate: 2-3 months. Their team built an AI agent to audit 100+ dependencies, handle 40 upgrades for New Arch, and open PRs in parallel. Full writeup from their team: expo.dev/blog/how-hip...

Build real apps. For real businesses. This is the concept for our Hackathon in Prague next week. If you're in Prague & you build apps go ahead and register. We'll be there to support the build process. And we'll provide credits to make sure you aren't blocked by anything. luma.com/Expo_STRV_Ha...

Seth is different. He can zoom out & see all the layers of a problem. He knows what to say. And what to build. And how to build it. What's possibly most impressive is that he delivers all this perspective with warmth and joy. It's infectious. We're lucky to have him! expo.dev/blog/seth-we...

🥳 We raised some money. Expo is the best it's ever been, and this round of funding will help us get a lot better. With this money we can go faster on the things that matter: faster builds, smoother native integrations, and better e-2-e DX. Charlie wrote about what's next: expo.dev/blog/what-ex...

Smaller JavaScript bundle updates = faster downloads and lower costs. Full guide below to help you optimize your OTA Updates with: ◆ Asset optimization and selection ◆ Hermes bytecode diffing (SDK 55 beta) ◆ Updates for testing, not builds expo.dev/blog/how-to-...

🍕 🍺 We're back in Post Alley next week for another Expo x AI meetup with @internetstudio.bsky.social 🎤 Jamil Islam will demo his AI video generation tool. 🎤 Dan Kelly is threatening to live demo Expo Agent. If you're in the seattle area come join this monthly AI app dev meetup: luma.com/tfs2j7by

We should talk about Expo Orbit more. It's a free, open-source menu bar app for macOS, Windows, and Linux. Install and launch builds on simulators and devices in one click. No more dragging archives manually 😅 https://expo.dev/orbit

You don't have to migrate your React Native app to Expo all at once. This guide breaks it into four phases, each delivering value immediately. Starting is simple. It's one command: npx install-expo-modules@latest https://expo.dev/blog/how-to-incrementally-adopt-expo

For a big client Infinite Red cut their CI from 20 minutes to 6 by combining EAS Workflows, Expo Fingerprint, and EAS Update. That's 230% faster, and it makes running Maestro e2e tests on every PR practical. https://expo.dev/blog/use-expo-ship-faster

EAS Update in SDK 55 now supports bundle diffing. Devices download a small binary patch instead of the full JavaScript bundle. A typical 3MB update drops to ~0.75MB. Opt-in now, default in SDK 56. https://expo.dev/blog/ship-smaller-ota-updates-bundle-diffing-comes-to-ota-updates-in-sdk-55

MyWheels migrated a complex brownfield React Native app from RNC CLI to Expo for faster builds, easier onboarding for web developers, and better collaboration across teams. This process has only gotten easier since SDK 55...check it out: https://expo.dev/blog/from-rnc-cli-to-expo

🙌 We've begun to invite more people from the Expo Agent waitlist into the beta. Join the waitlist if you're interested: https://try.expo.dev/agent-beta-waitlist

AI agents are shipping more PRs, but verifying mobile UI still needs a real device. New on the blog today: build a QA agent with EAS Workflows and agent-device that checks your app on iOS and Android for every PR. expo.dev/blog/build-a...

Small teams can't afford to chase broken dependencies. Fig (5 engineers, millions of users with food allergies) shares how they incrementally replaced community packages with Expo SDK modules after getting burned one too many times: expo.dev/blog/how-fig...

🙌 It's almost impossible to find a (non Expo) youtube tutorial covering Expo's Services. Until now. There is a massive new React Native crash course from the talented team at JS Mastery that covers SDK 55 and Expo's Services. youtu.be/4nVoLX2taFg?...

Built a progress bar with fun animated labels with @expo.dev

Fieldy builds an AI wearable that depends on Bluetooth, background processes & tight performance budgets. They didn't think Expo could handle it. Nine months in: 10% JS bundle reduction, 5MB off the binary, automated CI/CD with EAS Workflows. Here's their blog post: expo.dev/blog/how-fie...

🖤❤️ RNR 357 ❤️🖤 @mazenchami.dev and @robinheinze.dev catch up on the biggest React Native 0.82–0.84 and @expo.dev SDK 55 updates, from the new architecture and Hermes V1 to faster builds, better tools, and AI upgrades. Listen now 🎧 infinite.red/react-native...

💡 B2B mobile apps face a different adoption challenge than consumer apps. You're competing for budget approval and security reviews, not App Store attention. What actually works: fast onboarding, case studies, pilot programs, and long-tail keywords. Full guide: expo.dev/blog/5-prove...

Expo SDK 55 introduces the isolated brownfield approach: package your Expo app as a precompiled native dependency and embed it in your existing app. Swift & Kotlin devs never touch Node.js. React devs get a clear surface to contribute. Complexity stays contained. try.expo.dev/brownfield

You can now build iOS home screen widgets and Live Activities as React components in Expo. No Xcode target setup. Define your widget with @expo/ui & CNG handles the rest. ◆ Interactive home screen widgets ◆ Live Activities for Lock Screen and Dynamic Island expo.dev/blog/home-sc...
