We plugged our 𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚝𝚒𝚟𝚎-𝚗𝚒𝚝𝚛𝚘-𝚏𝚎𝚝𝚌𝚑 library into Bluesky's app and configured prefetching - it took us a whole 3 minutes and made the app load 500000000000000000000 zeptoseconds faster! 🤯 Try Nitro Fetch today! 📲

WIP SDK integration for Expo🧑‍🍳🧑‍🍳🧑‍🍳

A bit late to the party; this is pretext running in a small VisionCamera V5 Frame Processor using Skia for super-efficient realtime rendering in #reactnative 💬😍

We just released 𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚝𝚒𝚟𝚎-𝚏𝚊𝚜𝚝-𝚝𝚏𝚕𝚒𝚝𝚎 3.0.0, which has been fully rewritten to a Nitro Module! 🎉 This brings faster performance and bridgeless support for free, and fixes occasional SIGSEV crashes by switching to Nitro's 𝙰𝚛𝚛𝚊𝚢𝙱𝚞𝚏𝚏𝚎𝚛 type! 🥳

The videos showcasing how each navigator works in the React Navigation docs look absolutely stunning! Amazing job Satyajit Sahoo 🫶

🎥 Expo Router v55 Crash Course (link below)

It's finally done. I just released VisionCamera V5, the biggest update to VisionCamera ever, and my biggest open-source project ever (1/5) 🥳🎉🍾

VisionCamera V5 now supports Multi-Cam 👯 Stream from front + back simultaneously. Capture photos from both at once. Record Picture-in-Picture. Use the new imperative API to get started:

TypeGPU 0.11 doubles down on improving efficiency and providing more capable APIs: ⚡️ Highly efficient and convenient buffer write APIs ⚙️ Compile time and codegen improvements 📦 A complete rewrite of our bundler plugin Read the release notes and check out the example! Links

Full Blog Post out now: blog.margelo.com/margelo-discor…

The React Native community just got a new powerhouse of knowledge. 🚨 Margelo’s blog is now live. Expect deep dives into internals, performance, architecture, tooling, case studies, vision camera, and pixel-perfect mobile engineering. Built by engineers pushing the ecosystem

Hey, maybe we don’t need husky anymore!

VisionCamera V5 exposes a public NativeCameraOutput protocol so you can implement your own Camera Output in a Nitro Module and attach it to VisionCamera - without forking. At Margelo we've been building custom HDR pipelines for client apps. No more patches. No more forks. 🥳

Your JSI library might be slower than it needs to be. Small JSI architecture decisions can make code up to 2x–10x faster - we benchmarked what actually matters: - HostFunction vs HostObject - NativeState - Stack vs Heap If you care about performance, read this. 👇

Your PR builds don't need to recompile native code every time. Use Fingerprint + Repack to cut them by up to 78%. try.expo.dev/twitter

Heads up: Starting on April 28, 2026 apps uploaded to App Store Connect must be built with Xcode 26 or later using a compatible SDK. If you're on Expo SDK 54 or 55 - you're good. The default EAS Build image uses Xcode 26, so no action is required. If you're on SDK 53 or lower
