React Native / Mobile Apps

When to use this skill

• Building mobile apps with React Native or Expo.
• Managing navigation stack.
• Accessing native modules.

1. Expo ecosystem

• Expo Router: Use file-based routing (similar to Next.js) via expo-router.
• Config: Manage native permissions via app.json config plugins.

2. Styling

• NativeWind: Use Tailwind-like classes via nativewind if standard, or StyleSheet.create for performance-critical views.
• SafeArea: Always wrap top-level screens in SafeAreaView or handle insets manually.

3. Performance

• Lists: Use FlashList (Shopify) or optimized FlatList for long lists.
• Bridge: Minimize passes over the JS bridge. Use Reanimated for 60fps animations.
