How we build cross-platform mobile apps that rival pure Swift and Kotlin in speed, using Expo SDK 57, Reanimated gesture physics, and NativeWind styling.
01The New Architecture: Bridgeless TurboModules
With React Native's New Architecture enabled by default in Expo SDK 57, JavaScript communicates directly with native C++ host objects without serialization lag over the old async bridge. This guarantees true 60fps animations and instant gesture tracking.
Architectural Takeaways:
- Shared TypeScript codebase cuts mobile engineering costs by 50%.
- Seamless hardware integration: Camera, Biometrics (Face ID), Push Notifications.
- Over-the-Air (OTA) updates for rapid bug hotfixes.
