📌 Brief Summary
|
|
Optimizing games in React Native involves moving beyond the traditional bridge-based communication. By leveraging the JavaScript Interface (JSI) for direct synchronous calls and the Hermes engine for efficient bytecode execution, developers can achieve near-native performance for complex interactive systems.
|

|
📖 Core Content
|
|
* **JSI (JavaScript Interface):** Unlike the old bridge that required JSON serialization and asynchronous message passing, JSI allows the JavaScript engine to hold a direct reference to C++ host objects. This enables high-frequency updates (e.g., 60fps game loops) between JS and native modules.
|
|
* **Hermes Engine:** A JavaScript engine optimized specifically for React Native. It reduces app size, memory consumption, and "Time to Interactive" (TTI) by performing ahead-of-time (AOT) bytecode compilation.
|
|
* **TurboModules:** The evolution of Native Modules using JSI. It allows for lazy loading of native features, which is crucial for large-scale games to keep the initial memory footprint low.
|
|
* **Fabric Renderer:** The new concurrent rendering system that allows JS to communicate synchronously with the UI layer, reducing layout jumps and improving responsiveness in touch-heavy game interfaces.
|
|
* **Best Practices:**
|
|
* Use `react-native-reanimated` for JSI-based animations.
|
|
* Use `react-native-skia` for high-performance 2D graphics directly on the GPU.
