React Native / Expo Skill
Purpose
Build cross-platform mobile applications with React Native and Expo. This skill covers project setup with Expo, file-based routing with Expo Router, navigation patterns, native module integration, platform-specific code, performance optimization, and deployment with EAS Build. The goal: write once, run natively on iOS, Android, and optionally web.
Key Concepts
Expo vs. React Native CLI
EXPO (RECOMMENDED for most projects):
- Managed workflow: no Xcode/Android Studio needed for most features
- Expo Router: file-based navigation (like Next.js for mobile)
- EAS Build: cloud builds for iOS and Android
- Expo SDK: curated set of native modules (camera, auth, notifications)
- Over-the-air updates with EAS Update
REACT NATIVE CLI (when you need):
- Custom native modules not available in Expo
- Fine-grained control over native build configuration
- Brownfield integration (adding RN to existing native app)
DECISION: Start with Expo. Eject only if you hit a wall.

Expo Router Navigation
import { Stack } from 'expo-router' ;
import { ThemeProvider } from '@react-navigation/native' ;
export default function RootLayout (const colorScheme = useColorScheme
return
<ThemeProvider value ={colorScheme === 'dark' ? DarkTheme : DefaultTheme }>
<Stack >
<Stack.Screen name ="(tabs)" options ={{ headerShown: false }} />
<Stack.Screen name ="(auth)" options ={{ headerShown: false }} />
<Stack.Screen
name ="settings"
options ={{ presentation: 'modal ', title: 'Settings ' }}
/>
</Stack >
</ThemeProvider >

Platform-Specific Code import { Platform , StyleSheet } from 'react-native' ;
const styles = StyleSheet .create ({

...Platform .select ({
ios : { shadowColor : '#000' , shadowOffset : { width : 0 , height : 2 }, shadowOpacity : 0.1 },
android : { elevation : 4 },
web : { boxShadow : '0 2px 4px rgba(0,0,0,0.1)' },
}),

Safe Area and Responsive Layout import { SafeAreaView } from 'react-native-safe-area-context' ;
import { useWindowDimensions } from 'react-native' ;

const { width } = useWindowDimensions ();

Best Practices
Start with Expo -- eject to bare workflow only when truly necessaryUse Expo Router -- file-based routing is simpler and mirrors Next.js patternsTest on real devices -- simulators miss touch, performance, and hardware issuesUse SafeAreaView -- respect notches, home indicators, and status barsOptimize FlatList -- use keyExtractor, getItemLayout, windowSize for long listsMinimize bridge crossings -- batch native module calls, use Reanimated for animationsUse EAS Build -- cloud builds eliminate local environment issuesSecure sensitive data -- use expo-secure-store, never AsyncStorage for tokensHandle offline state -- check NetInfo, queue requests, show offline indicatorProfile with Flipper -- identify performance bottlenecks before they become problems
Common Pitfalls Pitfall Impact Fix AsyncStorage for tokens Tokens readable without encryption Use expo-secure-store Inline styles in FlatList items Re-renders on every frame Extract to StyleSheet.create No keyboard avoidance Input fields hidden behind keyboard Use KeyboardAvoidingView Ignoring safe areas Content under notch/status bar Wrap in SafeAreaView Large images without caching Slow loading, excessive bandwidth Use expo-image with caching No error boundaries White screen crash Wrap screens in ErrorBoundary
