|---|---|
| Greenfield Expo app | Expo Router (file-based, typed routes, deep links) |
| Bare React Native | React Navigation v7 (imperative, full control) |
| Brownfield / native modules | React Navigation v7 |
| Web + mobile | Expo Router (SSR, SEO) |
app/
├ _layout.tsx # Root layout (tabs, stack)
├ index.tsx # /
├ (tabs)/
│ ├ _layout.tsx # Tab config

Deep links work automatically. Universal links with app.json scheme config.
// app/product/[id].tsx
import { useLocalSearchParams } from 'expo-router'
export default function ProductScreen() {
const { id } = useLocalSearchParams<{ id: string }>()
// id is typed as string
}
type RootStackParamList = {
Home: undefined
ProductDetail: { id: string }
Cart: undefined
}
const Stack = createNativeStackNavigator<RootStackParamList>()
export function RootNavigator() {
return (
<NavigationContainer

prefixes: ['myapp://', 'https://myapp.com'],
config: {

<Stack.Screen name="ProductDetail" component={ProductDetailScreen} />
<Stack.Screen name="Cart" component={CartScreen} />
</Stack.Navigator>
</NavigationContainer>
)
}
| Scenario | Recommended |
|---|---|
| Simple, small app | React Context + useState |
| Medium app | Zustand (minimal boilerplate, hooks-based) |
| Large app, complex state | Redux Toolkit (mature ecosystem, DevTools) |
| Server state | TanStack Query (caching, refetch, pagination) |
import { create } from 'zustand'
import { persist, createJSONStorage } from 'zustand/middleware'
import AsyncStorage from '@react-native-async-storage/async-storage'
interface CartStore {
items: CartItem[]
total: number
addItem: (item: Product) => void
removeItem: (id: string) => void
clear: () => void
}
export const useCartStore = create<CartStore>()(
persist(
(set, get) => ({
items: [],
total: 0,
addItem: (product) => set((state) => ({
items: [...state.items, { ...product, quantity: 1 }],
total: state.total + product.price,
})),
removeItem: (id) => set((state) => ({
items: state.items.filter((i) => i.id !== id),
total: state.items.filter((i) => i.id !== id).reduce((s, i) => s + i.price, 0),
})),
clear: () => set({ items: [], total: 0 }),
}),
{ name: 'cart-storage', storage: createJSONStorage(() => AsyncStorage) }
)
)
| Rule | Implementation |
|---|---|
| Enable Hermes | hermes: true in metro.config.js |
| Use FlashList (Shopify) | Replaces FlatList — built-in recycling, better perf |
| InteractionManager | InteractionManager.runAfterInteractions(() => fetchData()) |
| Memoize components | React.memo on screen components, list items |
| Lazy load tab screens | lazy: true (default in Expo Router) |
| Image optimization | expo-image with cached, resized images |
| Avoid inline functions in render | Extract handlers, use useCallback |
| Freeze inactive screens | react-native-screens detaches from native hierarchy |
import { FlashList } from '@shopify/flash-list'
<FlashList
data={items}
renderItem={renderItem}
keyExtractor={(item) => item.id}
estimatedItemSize={120}
/>
Enabled by default in Expo SDK 53+.
| Component | Old | New |
|---|---|---|
| Native modules | NativeModules proxy | TurboModules (typed, synchronous) |
| View manager | Fabric not used | Fabric (synchronous rendering) |
| State updates | Bridge (async serialization) | JSI (synchronous, no serialization) |
Ensure compatibility:
// app.json
{
"expo": {
"platforms": ["ios", "android"]
}
}
import { useSharedValue, useAnimatedStyle, withSpring } from 'react-native-reanimated'
export function AnimatedCard() {
const scale = useSharedValue(1)
const animatedStyle = useAnimatedStyle(() => ({
transform: [{ scale: scale.value }],
}))
return (
<Animated.View
style={animatedStyle}
onTouchStart={() => { scale.value = withSpring(0.95) }}
onTouchEnd={() => { scale.value = withSpring(1) }}
/>
)
}
{
"expo": {
"scheme": "myapp",
"plugins": [["expo-linking"]]
}
}
Always implement a fallback for malformed links.
import * as Notifications from 'expo-notifications'
const { status } = await Notifications.requestPermissionsAsync()
if (status !== 'granted') return
const token = await Notifications.getExpoPushTokenAsync()
Notifications.addNotificationResponseReceivedListener((response) => {
const { screen, params } = response.notification.request.content.data
router.push({ pathname: screen as any, params: params as any })
})
eas build --platform all --profile production
eas submit --platform ios
eas submit --platform android
| Scenario | Cause | Fix |
|---|---|---|
| White screen on launch | Unhandled JS exception | Wrap root with ErrorBoundary, add Sentry |
| Deep link opens wrong screen | Missing or incorrect route config | Verify app.json scheme + linking config match |
| Push notification tap does nothing | No notification response listener | Register addNotificationResponseReceivedListener |
| FlashList blank / slow | Missing estimatedItemSize | Measure or estimate item height, pass to prop |
| Hermes crash on third-party lib | Lib not Hermes-compatible | Check lib docs, use Hermes-compatible version |
| EAS build fails on iOS | Missing provisioning profile | Run eas credentials, eas device:create |
| AsyncStorage 64KB limit on Android | Storage exceeds limit | Migrate to MMKV (react-native-mmkv) |
| Reanimated 4 worklet error | Using non-worklet code inside useAnimatedStyle | Only use Reanimated compatible functions inside worklets |
| TurboModule returns undefined | Fabric/TM not enabled | Verify newArchEnabled: true in app.json |
| Navigation state lost on restart | No persistence | Use persistNavigationState from expo-router or React Navigation v7 storage |
expo-image with resizeReact.memo on list items and screensInteractionManager.runAfterInteractions for heavy operationsexpo-constants env segregation (dev / staging / prod)| Anti-pattern | Fix |
|---|---|
| ScrollView for long lists | FlashList with virtualization |
| No Hermes | Enable Hermes — 2x startup improvement |
| Inline arrow functions in render | useCallback or extract to component |
| FlatList without optimization | Use FlashList instead |
| Deep linking as afterthought | Configure at project start |
| No error boundary | Unhandled JS error = white screen |
navigation.getParent() chains | Restructure to flat navigation hierarchy |
setState in navigation handlers | Navigate first, fetch on screen mount |
Using bare <Image> without dimensions | expo-image with explicit width/height |
| Zustand store split across 10 files | Keep logically cohesive, use slices pattern |
| New Architecture disabled by default | Enable newArchEnabled: true in app.json |
| Manual MethodChannel for native | Use Expo Modules API (typed, modern) |
| Ignoring platform-specific safe areas | useSafeAreaInsets from react-native-safe-area-context |
console.log in production builds | Strip via babel plugin (transform-remove-console) |
