After these optimisations, our tests went from ~10 minutes down to ~3 minutes!

I just optimised the heck out of my company's Maestro E2E tests with EAS workflows. I used a mix of repacking & a few other undocumented optimisations to Android Emulators. Here's what I've done. #expo #reactnative

Our CFP is OPEN 🔥 Chain React 2026 needs speakers who can level up 500+ React Native devs in Portland this July! All you need is a title and a strong idea. It takes 10 minutes to submit. Deadline: March 18. We want to hear from you. 🎤 sessionize.com/chain-react-...

i want youtube and podcast apps to support audio processing plugins so i can filter out the unbearable but trendy smart person vocal crutch of repeating “you know” (often abbreviated to something like “yeow”). i really would like to watch dario interviews but i cannot. note: i am mildly misophonic

Huge thanks to @expo.dev for featuring our journey with DEPOT on their blog! Big thank you as well to @baumstumpf.bsky.social for the editorial support 🙏 The path to success was built one step at a time - and those incremental improvements compounded to really pay off. 🚀

wow congrats @reedharmeyer.bsky.social techcrunch.com/2026/01/26/t...

llms now seem to be good enough to build side projects that i never would have otherwise bothered to build. this is cool

🆕 This PR from @nishan.dev adds CSS grid support to react native 🙌 It's not possible to overstate how massive this is for all of us. Future generations will celebrate Nishan Bende Day 🐐 github.com/facebook/yog...

is it just me or did americans recently decide, without consulting the rest of us, to suddenly start speaking with a hard g in “singer”? like sing-ger

message me here or come talk with me at @reactnativelondon.co.uk next week if this job posting looks like a good fit for you! expo is an amazing place to work! expo.dev/careers/web-...

as someone who very much enjoys @chasebliss.bsky.social pedals, i am so stoked that this app exists and that it was built using tools that i work on expo.dev/blog/buildin...

𝝠 Expo passed 2 Million weekly npm downloads over the weekend. It wasn't a milestone we were tracking or aiming for. But it feels great to get there. It's a credit to the hardworking team at Expo and to the community of devs that contribute and support Expo. Thank you!

💂‍♀️ If you're anywhere near London next month then make your way to RNL Conf. This is a talent-rich event with wonderful speakers, panels, and workshops. We've got a massive cohort of Expo devs headed to London and we'd love to see you there. www.reactnativelondon.co.uk

made my first leaflet :) a little guide to our new @atproto/oauth-client-expo library

app devs: we have some new AT OAuth resources and examples for you! linked off this intro page we have new example projects showing how to do client auth using reference SDKs for TypeScript and Go. and the buried lede: an Expo library for doing AT OAuth in React Native mobile apps

New Automerge website at automerge.org. Kudos to @spiralganglion.com and @seaofclouds.com for their work building it. The level of craft and detail in the landing page is very satisfying.

🎉 Introducing React Native Harness - a lightweight framework for testing native modules directly on device or emulator. Write tests in a Jest-like syntax, run them in a real React Native runtime, and verify native behavior without mocks.

very interesting talk by @lunaleaps.bsky.social from the second day of react conf about RN threading and virtualizating lists, highly recommend watching

Love how much of the latest @reactnative.dev release is removal and deprecations! github.com/facebook/rea... While it might cause downstream friction, it's such a healthy sign for a project to not "just add on" but tackle its technical debt head first! I hope this doesn't stop if we ever get to 1.0!

We just launched a new React Native showcase for Meta Quest VR 🚀 Our demo on Horizon OS features camera, audio, and fluid navigation powered by popular libraries. It proves you can use existing mobile skills to build high-performance VR experiences. Read the full story by @jwr.ski on our blog ⬇️

🆕 AI apps don’t need the cloud. With react-native-executorch, you can: ♢ Keep data private ♢ Run AI offline ♢ Skip API fees ♢ Get instant responses On-device AI is here. Read about it in the blog post from @swmansion.com → expo.dev/blog/how-to-...

i wrote about atproto and why it matters

for all the cracked react native devs, please come with with us 🥺

👀 We've had the pleasure of meeting @alfonsocj.com in person at a couple events (including Chain React where he gave a great talk about building with Expo at Coinbase). He would be excellent to work with. Take a look at this role if you're available or your eyes are beginning to wander:

"I'm new to React Native / Expo Router - how should I structure my codebase?" It's a question that comes up quite a bit, and this is an attempt at providing some very concrete suggestions. Already using Router? I'd love to know if there's anything you'd do differently, and why 📝

hello! have you migrated your app to the new arch recently? how'd it go for you? curious to hear success stories, failed attempts, and anything in between!

Expo Go just made it to the metaverse: www.meta.com/experiences/...

TIL that for some people with irreparably damaged corneas, you can pull one of their teeth, drill a hole in it, install an artificial lens, sew it into their cheek (so tissue attaches), then pull it out and stick it in their damaged eye, and ... it works fine!?! www.nbcboston.com/news/health/...

Try out Expo UI on both mobile and TV! 😀 github.com/react-native...

I'm stoked to share that I've joined @expo.dev as a Developer Success Engineer! Thankful for the opportunity to work full-time with the tech, the talented team, and community I admire so much! Today is my second day, and I'm so excited for what's ahead!

🏎️ React Native precompiled SDK 53 vs SDK 54 Speed Test In a real app from one of my projects Thanks to @chrfalch.bsky.social 🫡

Had some spare time this morning and took @expo.dev SDK54's new native tabs in expo-router for a spin. The API feels great. Native tabs are a big piece of the puzzle- and now with native, JS, and custom tabs, it’s easier than ever to match any app’s design language 🚀

We are excited to announce the release of React Native 0.81! 🎉 This new version brings Android 16 support, faster iOS builds (experimental), and several bugfixes. reactnative.dev/blog/2025/08...

Took me a while to get it right on Android from 7 to 16, with edge-to-edge enabled or not, new arch enabled or not, but I fixed the Dimensions API: github.com/facebook/rea... Finally, correct window dimensions & values update on split screen changes! ✨
