tomevault-io Mobile React Native Skill
Core Principles
- Expo managed first: Only eject when a native module is absolutely needed.
- FlatList not ScrollView: For lists > 50 items — ScrollView renders all at once.
- Reanimated on UI thread: Animations must not trigger the JS bridge.
- MMKV for storage: 10x faster than AsyncStorage for non-sensitive data.
- Zustand for client state: Redux is overkill for most mobile apps.
