# 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

| Feature | Expo | Bare RN |
|---------|------|---------|
| Setup complexity | Low | High |
| Native modules | EAS Build | Manual linking |
| OTA updates | Built-in | Manual setup |
| Build service | EAS | Custom CI |
| Custom native code | Config plugins | Direct access |

## Quick Start

```bash
# 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
```

```typescript
// 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 scre
