@SantoshYadavDev @nishanbende Nishan is an absolute 🐐

[Alek Mikucki @aleqsio]

@iwoplaza oh no, terrible

[Seth Webster @sethwebster]

Yes it does. A fantastic conference from @swmansion and @expo — so glad to take part. What an inspiring week of content, connection and camaraderie. Great to see everyone!

[Alek Mikucki @aleqsio]

@Baconbrix What an incredible run. You’ve been an absolute inspiration to me on what a high impact product engineer can achieve!

[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!

@arynationw @anakagungcorp @blazejkustra_ @swmansion expo-ui is actually built on a native swiftui component not a js library 😅

[Kudo @kudochien]

Watching @appjsconf livestream and time to share a small SDK 56 secret 👀

We've added some experimental Expo Modules performance improvements on iOS with @tsapeta.

`ExpoCrypto.randomUUID()` is seeing around ~75% performance improvement 🚀

[Tomasz Zawadzki @tomekzaw_]

Stability of React Native apps is critical for us 🛡️

Send me your stack trace – I'll dig in and try to fix it ✨

The most obscure crash wins some @appjsconf swag (only if you're a participant) 🍀

Explainer:

I'm experimenting with html-in-canvas – seeing how far we can take it. Performance is pretty mid and stuff like videos is not working, I'd say only 50% of sites work so far.

A lot of hacks went into this, tbh hoped it would be easier but html-in-canvas requires the element to be a direct child, so this modifies stylesheets in a service worker to clone the html tag into a canvas, lol.

Are you bored with how clean and readable modern websites are?

I am, so I'm building a chrome extension that turns any website into a CRT TV 📺

[Software Mansion @swmansion]

Local models are becoming increasingly capable in agentic workflows 🪄

Here’s @googlegemma 4 controlling the iOS simulator with Argent 👇

[Kacper Kapuściak @kacperkapusciak]

I used Argent by @swmansion to play 2048 on an Android emulator

This video is NOT sped up. Works pretty well!

[Alek Mikucki @aleqsio]

A bit of an early warning, but I'll be in NY 13-20th June in case anyone wants to go grab a coffee together and talk RN!

Lots to unpack here!

In this Expo UI release, we focused on bringing Jetpack Compose support to parity with SwiftUI.

We also added worklets support, so you can drive native SwiftUI/Jetpack Compose state from JS on the UI thread, making sync patterns and truly controlled form controls possible, like flicker-free text inputs.

[Alek Mikucki @aleqsio]

@expo this is huge! so many great changes landing,

[Leon @LeonDvlpmnt]

Adding expo modules to your app will become a lot easier. @expo SDK 56 will have experimental support for inline modules, which means you can colocate kotlin/swift modules directly in your codebase

[Łukasz Kosmaty @lkosmaty]

Really excited about this one. New Kotlin compiler plugin in Expo SDK 56 replaces reflection with build-time code gen for Expo Modules on Android. ~40% faster cold starts, ~33% faster first render in our benchmarks. No changes needed in your app!

Mogę zrozumieć zaktualizowanie katalogu urządzeń objętych opłatą (choć podciąganie smartfona pod urządzenie podobnych do kserokopiarki jest moim zdaniem mocnym naginaniem ustawy).

Nie mogę za to zrozumieć próby wmawiania wyborcom, że ten podatek płacą korporacje, nie kupujący. W tym biznesie marże są małe a ceny urządzeń ustalane przez zagranicznych producentów.

Jako wyborca jestem mocno tym wszystkim zniesmaczony – wystarczyło przegłosować zmianę ustawy a nie pchać rozporządzeniem.

@p_stasiak @varsovie_style o, ale moloch xd
