π Thank you @ReactSummit Amsterdam!
You made us feel like stars. This was our first time sponsoring the event and we loved it. We'll see you again next year π«‘.
We're taking all this big, nerdy momentum and riding it into Chain React Conf next month. Limited time only 50% discount in this link: ti.to/chainreact/chainreact2β¦
Hope to see you in Portland π²

Here's Expo''s biggest CICD differentiator: Fingerprint repack:
β It checks if your native layer actually changed
β If it didn't, skip the full build
β Repack the last binary with the new JS on top
With this workflow a ~15 min build becomes ~2 min.

Your iOS builds just got faster. No changes required.
SDK 56 ships Expo modules as precompiled XCFrameworks: instead of compiling them from source on every build, your app links binaries that were already built.
On by default, locally and on EAS Build. @chrfalch shares all the details β

Chain React Conf is important.
This is the only North American conference where React and React Native devs can gather in person to trade ideas (and feelings) about how software development is changing.
The talks we have curated for the event are going to alter careers.
Grab your tickets in the post from @jamonholmgren below.

π How a Kotlin compiler plugin cut Android time to first render by 30%
βοΈ @lkosmaty
SDK 56 replaces runtime reflection in Expo Modules with a K2 compiler plugin, making Android module init 70% faster with no code changes.

π ππ‘ππ/ππππππ-πππππ is moving to deprecated.
The πππππ-ππππππ-ππππππ-πππππ packages now integrate directly with expo-font and work in Expo Go, dev builds...the whole thing.
The change is going to require a bit of effort. But it'll simplify your codebase and lead to more predictable builds. We're also seeing smaller binaries (~4MB lighter).

Iβm super excited to announce Iβve joined @expo as a Developer Success Engineer! π₯³
Kind of surreal, honestly. Iβve been building with Expo on a ton of projects for a while now, and itβs shaped how I think about building apps more than anything. And thereβs a lot happening in the React Native world right now, so getting to work on it from the inside, plus making content that helps other devs build better and faster, feels like exactly where I want to be.
Looking forward to spending a lot more time with this community π

react-native-livechart is live π₯³
Beautiful, reliable live charts for React Native: (multi-) line and candlestick, smooth at 60fps even with 10 trades a second coming in.
TL;DR: npm install react-native-livechart; deep dive π
