gov uk "one login" is turning into somewhat of a "none or two logins" for me since it doesn't seem to compute that all UK agencies have chosen to transliterate my name differently 🥲

Introducing Expo Agent (beta): build real, production-quality native apps from your browser YouTube video by Expo

🙌 Introducing Expo Agent

Build truly native iOS and Android apps from a prompt. Anything from React to SwiftUI to Jetpack Compose.

Compile and deploy for Apple, Android, and the web right from the browser!

damn, these keyboard interactions are well nice ❤️ love it!
(liquid glass wen?)

quality of life feature in @expo.dev 55, iOS dev builds using expo-dev-client will discover devservers on the local network automatically ✨📡 qr codes are finally fully optional now 😄

bit of a funny blunder to do a big, transparent & comprehensive ToS change + notification to then accidentally write that you have to be 18 to use Zed implying the software when you meant (as per the terms) the service/subscription 😅

but if there's anything you'd like to seein the upgrade guide or otherwise, let us know, and we'll get it updated

mainly there's details in upgrades that differ from project to project. a lot of the versioning/deps issus are fixed since 54, and 55 improves on that. expo-doctor also catches a lot of details. But the "rest" can be unpredictable but LLMs have a large amount of implicit knowledge that helps,

the skill doc (github.com/expo/skills/...) doesn't contain anything the changelog wouldn't or that the guide here doesn't (docs.expo.dev/workflow/upg...). it's easy to forget small details though (resolution, patches, 3rd party deps upgrades, deprecations in the changelog, etc)

happy belated christmas ❤️

haven't tried it out myself yet, but is SWM's react-native-enriched not living up to the hype for you? 😔

Expo SDK 55 - Expo Changelog Learn about the changes and how to upgrade

Expo SDK 55 is out 😅
RN 0.83, React 19.2 & a long list of things that make your app faster, smaller, & easier to build

♦ Hermes bytecode diffing cuts update sizes by ~75%
♦ Brownfield support gets a serious upgrade
♦ MCP now queries EAS + TestFlight crashes

Full changelog: expo.dev/changelog/sd...

Startup screen in Expo showing the QR code and the help output. The help output omits most key instructions, and the QR code is rendering at an increased density (smaller)

small detail in Expo SDK 55 (beta) 🧹 the startup output will reduce itself in short terminal windows, and smaller QR codes render in terminal apps that support it

ESM support is pretty much there. There's some resolution quirks since we're trying not to break everyone's apps all at once (adding package.json:exports was rough enough for most) but happy to accept issues if anything seems off or goes wrong

and Bun had some quirks and 1.3.1 (?) fixed most of them and isolated installations (now their default) isn't prone to some of those anyway, but I suspect it might still need a bit of time

generally, installation issues are hard and frustrating to spot so avoiding them is nice

hoisting is tricky and when testing against all package managers there were some odder issues that npm/yarn/yarn berry ran into. Since there's technically no upside to using them, I usually recommend pnpm which is (as far as I can tell) not prone to any hoisting/peer bugs or quirks

Work with monorepos Learn about setting up Expo projects in a monorepo with workspaces.

with Expo 54 all work and the docs have been updated to reflect this: docs.expo.dev/guides/monor...
personally, I'd recommend Bun and pnpm over others. pnpm if correctness is most important. disabling isolated installations isn't necessary any longer either

ram cleaner aah vibe

4. the repo isn't quite complete in terms of tests/benchmarks, but I ran it in some other libs benchmarks and it's relatively fast

5. yes, this isn't a novel library or new idea, but just something we'd like to own since the need for these formats exist in almost all parts of Expo

some more context...

1. this currently powers internal APIs in EAS Hosting and Launch at @expo.dev

2. might move this to the Expo GH org in the future, TBD

3. It's a smol API with some added utils so not a full node-tar/tar-fs replacement but a place for us to put general stream format code

GitHub - kitten/multitars: Multipart and Tar utilities for the Web Streams API Multipart and Tar utilities for the Web Streams API - kitten/multitars

📦 multitars

we're starting to share around some tar & multipart en-/decoding code at expo, so it's published separately now. We needed tar/multipart support that's memory efficient and based on the Web Streams API

damn, this new ai code editor is awesome

and thank you to all that submitted! you didn't make it easy to pick our nominees, and we appreciate all of you!

we're hoping to get a list of honorable mentions, apps on the horizon, shout-outs, and apps that also stole our hearts compiled by the end of the awards ❤️‍🔥

we got 1000+ submissions, and I looked at ~600 submissions and hand tested well over 100 apps over the past few days, as just one of our reviewers.

congratulations to the nominees & your apps! 💯🎉

clearly they must be struggling to follow the recipes

💂‍♀️ 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.

i mean, currently Metro doesn't have tree shaking. From Expo's perspective, our goal is to start stabilising it as a feature but we'd make it export-all aware. From the standpoint of circular imports, live bindings make this mostly safe. But there can still be gotchas

GraphQL Myths Common misconceptions about GraphQL and how persisted operations address them.

The 3 worst GraphQL myths:

❌ Everything is POST
❌ All URLs are /graphql
❌ Anyone can query anything
