Frontend Rn Expo

React Native + Expo (stack-specific layer)

Trigger phrases: "expo", "react native", "native bridge", "expo router", "rn screen", "prebuild"

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.
