React Native Architecture

Production-ready patterns for React Native development with Expo, including navigation, state management, native modules, and offline-first architecture.

When to Use This Skill

Starting a new React Native or Expo project
Implementing complex navigation patterns
Integrating native modules and platform APIs
Building offline-first mobile applications
Optimizing React Native performance
Setting up CI/CD for mobile releases

Core Concepts

1. Project Structure

src/
├── app/                    # Expo Router screens
│   ├── (auth)/            # Auth group
│   ├── (tabs)/            # Tab navigation
│   └── _layout.tsx        # Root layout
├── components/
│   ├── ui/                # Reusable UI components
│   └── features/          # Feature-specific components
├── hooks/                 # Custom hooks
├── services/              # API and native services
├── stores/                # State management
├── utils/                 # Utilities
└── types/                 # TypeScript types

2. Expo vs Bare React Native

Quick Start

# Create new Expo project
npx create-expo-app@latest my-app -t expo-template-blank-typescript

# Install essential dependencies
npx expo install expo-router expo-status-bar react-native-safe-area-context
npx expo install @react-native-async-storage/async-storage
npx expo install expo-secure-store expo-haptics

// app/_layout.tsx
import { Stack } from 'expo-router'
import { ThemeProvider } from '@/providers/ThemeProvider'
import { QueryProvider } from '@/providers/QueryProvider'

export default function RootLayout() {
  return (
    <QueryProvider>
      <ThemeProvider>
        <Stack screenOptions={{ headerShown: false }}>
          <Stack.Screen name="(tabs)" />
          <Stack.Screen name="(auth)" />
          <Stack.Screen name="modal" options={{ presentation: 'modal' }} />
        </Stack>
      </ThemeProvider>
    </QueryProvider>
  )
}

Best Practices

Do's

Use Expo - Faster development, OTA updates, managed native code
FlashList over FlatList - Better performance for long lists
Memoize components - Prevent unnecessary re-renders
Use Reanimated - 60fps animations on native thread
Test on real devices - Simulators miss real-world issues

Don'ts

Don't inline styles - Use StyleSheet.create for performance
Don't fetch in render - Use useEffect or React Query
Don't ignore platform differences - Test on both iOS and Android
Don't store secrets in code - Use environment variables
Don't skip error boundaries - Mobile crashes are unforgiving
