React Native New Architecture: Fabric & TurboModules
React Native has historically relied on an asynchronous JSON bridge for JS-to-Native communication. The New Architecture completely changes this by introducing the JavaScript Interface (JSI).
1. The JavaScript Interface (JSI)
JSI allows JavaScript to hold reference to Native C++ host objects. This means you can call native methods directly and synchronously, removing the JSON serialization overhead.
2. Fabric Renderer
Fabric is the new concurrent layout rendering engine. It runs synchronously, enabling fluid user interactions, high-speed list scrolling, and instant UI responsiveness without thread bottlenecking.
3. TurboModules
TurboModules allow native modules to be lazy-loaded on demand instead of being fully initialized at app startup. This drastically decreases cold launch times for complex apps.
Final Thoughts
Embracing JSI and Fabric is crucial for future-proofing your mobile apps. Start configuring your NativeModules using C++ interfaces today.
Happy Coding!
