Does this skill work with Expo?

Absolutely. It includes Expo-specific optimizations such as using expo-image for better caching and performance compared to the standard Image component.

Can it help reduce my app's bundle size?

Yes, it includes strategies for bundle analysis, optimizing imports (e.g., date-fns or icons), and replacing heavy libraries like Moment.js with lightweight alternatives.

How does this skill help with React Native scrolling lag?

The skill provides specific implementation patterns for replacing FlatList with FlashList, using estimatedItemSize, and memoizing list items to ensure smooth 60fps scrolling.

What profiling tools does this skill recommend?

It guides users through using the React DevTools Profiler, Flipper for advanced debugging, and the native Performance Monitor to track FPS and memory usage.

Mobile Development

Optimizes React Native applications by implementing best practices for rendering, lists, images, and animations.

Acerca de

The React Native Performance skill provides a comprehensive toolkit for diagnosing and fixing performance bottlenecks in mobile applications. Grounded in the principle of profiling before optimizing, it offers implementation patterns for memory management, stable render references, and high-performance alternatives to standard components like FlashList and Reanimated. This skill is essential for developers looking to achieve 60fps animations, reduce application bundle sizes, and eliminate scrolling jank in complex cross-platform interfaces.
