🎙️ Expo Speech
💾 SQLite async storage
🧭 Router UI
🔄 Background tasks
🧠 API routes (yes, full stack in Expo)

React Native is getting faster—and greener—with precompiled packages.

🔧 One build per release instead of one per dev
⚡ RNTester clean builds: 120s → 10s (M4 machines)
🌿 Lower power usage, better battery life
🧩 Easier to add to large brownfield apps

In the blog post from @notbrent.dev and @chrfalch.bsky.social they demonstrate some exciting benchmarks from our own internal testing:

Precompiled React Native for iOS: Faster builds are coming in 0.81 React Native 0.81 introduces precompiled iOS builds, cutting compile times by up to 10x in projects where React Native is the primary dependency.

⚡ We teamed up with Meta to deliver precompiled iOS builds in 0.81/SDK 54. You get:

◆ Faster builds: Compile RN once per release
◆ Smoother integrations: Easier to add RN into brownfield apps
◆ Future-proof: Prepares RN for migration from CocoaPods to Swift Package Manager

YouTube video by Expo Repack Workflow Demo

Your CI builds are wasting time.

You don’t need a full native build every time you run tests.

In his new video @codewithbeto.dev shows how to cut build times from 25 → 5 minutes with:

⚡️ Expo Repack
🧬 Expo Fingerprint
🔁 EAS Workflows

Architecture of Wine AI: A camera-powered sommelier with Expo See how one solo dev built Wine AI with Expo—an app that scans wine labels and returns tasting notes, pairings, and reviews using AI.

🍷 What if you could snap a photo of a wine label and instantly get tasting notes, food pairings, reviews - all powered by AI?

That's what @meerhabib.bsky.social built in two weeks with Expo, OpenAI, @supabase.com and @revenuecat.com.

Read his post to learn how he did it:

Let us know when the app ships. Would love to check it out.

We love to hear it!
