Ever wondered why animations on #reactnative's new architecture were so laggy?
We partnered with the @discord team, found the bottlenecks, and helped make their mobile app feel buttery smooth.
Hereβs the before/after π

VisionCamera β€οΈ Skia β€οΈ Reanimated
Jun 11
Built a quick CapWords AI-inspired demo πΈβ¨ And template of @makeitanimated
Features:
β’ Snap a photo
β’ On-device object detection & extraction
β’ Smooth animated overlays and transitions
Built with:
β’ Expo @expo
β’ Native Module for object detection
β’ VisionCamera @margelo_com
β’ Skia @ReactNativeSkia
β’ Reanimated @swmansion
β’ react-native-screen-transitions @trpfsu
Pretty impressed by how far on-device AI experiences can go without relying heavily on cloud APIs.
Still polishing the UX, but the core flow is already working π
Would love to hear your thoughts π

Four years ago, react-native-quick-crypto was just a way to make crypto faster for wallet apps.
Today, it's grown into one of the most complete crypto implementations for React Native.
Here's what the latest benchmarks look like π

We just updated our agent skills after days of non-stop testing, benchmarking and iterating - Codex was now able to one-shot a Nitro Module with super efficient and elegant API design. We'll release the library next week! β¨
Try our skills now π

We just released react-native-runtimes! π₯³
π Render React components on separate JS Runtimes
π Share state (Zustand) across Runtimes, synced in C
π Dual-Thread-approach for rendering/business logic
We plugged this into MetaMask which made the app start substantially faster:

So we kinda reinvented the wheel and built a fully custom AV engine and composition library for MyGroove because ExoPlayer, AVFoundation and ffmpeg weren't fast- or powerful enough π

We'll write a blog post about the full story soon π
In the meantime check out the MyGroove app to see our AV engine in action π mygroove.eu.go.link/zS7mv

Many people don't realize that Nitro Fetch is faster even without prefetching or other advanced optimizations. This is the performance gains we achieved in Bajaj Finserv Health's Doctor app simply by replacing the Axios adapter with Nitro Fetch.
