Performance Optimization — React Native Roadmap
Keeping a React Native app smooth on real, mid-range devices
Steps in Performance Optimization
- Optimizing List Rendering (FlatList Performance) — advanced · windowSize, getItemLayout, removeClippedSubviews and other FlatList tuning techniques
- Image Optimization & Caching — advanced · Resizing, caching and lazily loading images to avoid memory and network pressure
- Reducing Bridge Traffic — advanced · Minimizing the serialized data crossing between JavaScript and native
- Hermes JavaScript Engine — advanced · How Hermes improves startup time and memory usage compared to JSC
- Profiling with Flipper — advanced · Diagnosing real performance bottlenecks instead of guessing
- Reducing App Startup Time — advanced · Lazy loading, reducing bundle size and deferring non-critical work at launch
