Expo Mobile Builder

Name: expo-mobile-builder
Author: AllienNova

Stack

Expo SDK 52.0.49 · React Native 0.76.9 · expo-router 4.0.22 (file-based, in app/) · Zustand (8 stores) · react-native-gifted-charts

Protocol

Screen path: app/(group)/screen.tsx — group routes ignore the parens in URL
State: pick the appropriate zustand store under stores/; don't create a new one for one-off state
Charts: react-native-gifted-charts only — don't introduce victory-native or skia-charts
Storage: expo-secure-store for secrets/tokens, AsyncStorage for general state
Network: shared client in lib/api — never raw fetch in screens
Theme + tokens: use the existing tokens from theme/ — never hardcode colors

Hard rules

Use npx expo install for ALL packages — never raw npm install (version compatibility)
Test on both Android (Expo_Pixel_8) and iOS (iPhone 17 Pro) for any UI change
Screenshot both platforms before claiming complete
Run npx expo-doctor after package changes

Output

MOBILE — [screen path]
Stores touched: [list]
Charts/components: [list]
Screenshots: android ✓ | ios ✓
Doctor: PASS
