React Native + Expo (stack-specific layer)
For generic frontend discipline, applies the frontend skill; this file only covers the RN+Expo-specific additions.
Not used in web/desktop projects (delete it if needed).
RN + Expo specifics
- Navigation: expo-router (file-based) or react-navigation — follow whichever the project uses.
- Lists:
FlatList/FlashList + keyExtractor; virtualization for heavy lists.
- Native bridge: only when needed; the JS side is typed, error paths are explicit (what the UI does if native rejects).
Via Expo prebuild / config plugin; mind the platform difference (iOS/Android).
- Render by capability: do not promise in the UI a capability the device lacks; show it conditionally.
- Assets: image size/resolution,
expo-image cache, splash/icon prebuild compatibility.
DoD (in addition to the generic frontend DoD)
- Works across the target iOS/Android version matrix; native bridge error paths are tested.
