Expo SDK 56 is out 🙌

◆ Expo UI is stable on iOS and Android
◆ iOS builds 16% faster, plus another 20% on EAS from precompiled community libs
◆ Android cold starts 40% faster
◆ Expo Router decoupled from React Navigation
◆ Inline native modules: write Swift and Kotlin right next to your TypeScript
◆ Hermes v1 by default
◆ Bytecode diffing on by default (~58% smaller OTA updates)
◆ iOS Widgets stable
◆ React Native 0.85 + React 19.2

It's been two months since SDK 55, and we packed in everything we could fit. Your iOS build times are going to thank you. Full changelog ↓

🚀 Expo Router v56 comes with the biggest shift to the library since it launched.

You've probably already read about us forking React Navigation. In the blog below you'll get all the details but essentially we needed to fork in order to control/tune the internals. This unlocks some big improvements we can make moving forward.

Here are a few of the other highlights:

◆ Imports move from @𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚟𝚒𝚐𝚊𝚝𝚒𝚘𝚗/* to 𝚎𝚡𝚙𝚘-𝚛𝚘𝚞𝚝𝚎𝚛/𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚟𝚒𝚐𝚊𝚝𝚒𝚘𝚗
◆ A codemod handles it
◆ Library imports auto-rewrite for one release cycle
◆ Streaming SSR + 𝚐𝚎𝚗𝚎𝚛𝚊𝚝𝚎𝙼𝚎𝚝𝚊𝚍𝚊𝚝𝚊
◆ Type-safe loaders: 𝚌𝚛𝚎𝚊𝚝𝚎𝚂𝚝𝚊𝚝𝚒𝚌𝙻𝚘𝚊𝚍𝚎𝚛, 𝚌𝚛𝚎𝚊𝚝𝚎𝚂𝚎𝚛𝚟𝚎𝚛𝙻𝚘𝚊𝚍𝚎𝚛
◆ Android toolbar (left, right, bottom)
◆ Native Tabs gains 𝚍𝚒𝚜𝚊𝚋𝚕𝚎𝚍

1. Add your folder to 𝚠𝚊𝚝𝚌𝚑𝚎𝚍𝙳𝚒𝚛𝚎𝚌𝚝𝚘𝚛𝚒𝚎𝚜 in the app config
2. Run 𝚗𝚙𝚡 𝚎𝚡𝚙𝚘 𝚙𝚛𝚎𝚋𝚞𝚒𝚕𝚍

Any Swift or Kotlin file in that folder gets compiled and autolinked. Grab it from JS with 𝚛𝚎𝚚𝚞𝚒𝚛𝚎𝙽𝚊𝚝𝚒𝚟𝚎𝙼𝚘𝚍𝚞𝚕𝚎('𝙸𝚗𝚕𝚒𝚗𝚎𝙼𝚘𝚍𝚞𝚕𝚎').

You can also stop writing TypeScript interfaces by hand. The new 𝚎𝚡𝚙𝚘-𝚝𝚢𝚙𝚎-𝚒𝚗𝚏𝚘𝚛𝚖𝚊𝚝𝚒𝚘𝚗 package reads your Swift module and generates the matching TS types. Leave it in watch mode and they update as you edit the native code.

Your next native module can live right next to your 𝙰𝚙𝚙.𝚝𝚜𝚡.

In Expo SDK 56 we added inline native modules. Create a 𝙽𝚊𝚝𝚒𝚟𝚎𝚅𝚒𝚎𝚠.𝚜𝚠𝚒𝚏𝚝 beside your app files and write Swift there. Nothing to scaffold first.

Setup takes two steps ↓

Calorie Snap demo🍊🍌🍩 built with:
• expo ui - expo module @expo
(ModuleVNGenerateForegroundinstance) for on device food extraction
• vision camera @margelo_com
• skia @ReactNativeSkia
• reanimated @swmansion
• and of course screen-transitions by @trpfsu
Thanks to all 🙏
Btw, I'm currently looking for remote full-time or part-time (based in Vietnam) React Native opportunities. DMs are open 💪🙏
Thanks guys!!!

We’re back at CascadiaJS today. Let us know if you’re in Seattle and want to meet up.

[Jimmy Lee @wwwjim]

My personal hero @JI from @expo presenting about linked literate programming. So thrilled to be at @CascadiaJS for this !!

Native templates now available on App Store and Play store 🚀

https://t.co/Zvy64CuTYH

You can now preview all the templates directly in the app and get notified about the new ones.

Built with @nativewindcss @reactnative and @expo SDK 56.

@hokage_wws 💯agreed.

What’s the app?

🥓 @Baconbrix is one of the elite product builders on the planet. Full stop.

Until you see it up close, every day, it’s impossible to know what it means to operate at his level. His blog post below is a real gift. He’s distilled a handful of the practices that make him elite.

Of course we will miss Evan dearly. But mostly we feel grateful. Expo got 9 years of relentless development and uncommon vision. There will not be a single day that our team and our users do not continue to feel the impact of his work.

Thank you Evan. For everything. We cannot wait to see what you do next! 🫶

[Evan Bacon 🥓 @Baconbrix]

After 9 years, I just finished my last week at Expo.

Started working on it when I was 19, and it's been the center of my life ever since.

Incredibly grateful to the team and community we built along the way!

[Expo @expo]

@wwwjim @Baconbrix Jimmy did you hire Evan originally?

[Expo @expo]

@p_d_y @Baconbrix 🐐🐐🐐

@martindonadieu @Baconbrix He made a lot of expo.

@BenjaminKomen @kadikraman That’s good to hear! Keep the feedback coming.

[Expo @expo]

🆕 Today we open up the beta for our new mobile Observability service.

If you've ever shipped a release and felt uneasy for the next 24 hours...this service is for you.

@kadikraman's App.js talk from today goes into excellent detail. We'll share that link below and a page where you can get started with the beta ↓
