```tsx
import { FigoProvider, ChatInterface } from '@figo-ai/react-native-sdk';

export default function App() {
  return (
    <FigoProvider
      config={{
        apiKey: 'your-api-key',
        customerId: 'customer-123',
        connectionId: 'postgres-prod',
      }}
    >
      <ChatInterface />
    </FigoProvider>
  );
}
```

That's it! You now have a complete chat interface with:
- ✅ Real-time streaming

const client = new FigoClient({
  apiKey: 'your-api-key',
  customerId: 'customer-123',
  connectionId: 'connection-456',
  baseUrl: 'https://api.figo.ai', // Optional
  enableAnalytics: true,           // Optional
  debugMode: false,                // Optional
});

// Initialize and authenticate
await client.initialize();

// Check authentication status
const isAuthenticated = await client.isAuthenticated();
console.log('Authenticated:', isAuthenticated);
```

## Configuration

### Required Parameters

- `apiKey`: Your Figo AI API key
- `customerId`: Unique customer identifier
- `connectionId`: Database connection identifier

### Optional Parameters

## Core Services

### Conversation Service

Manage AI conversations with full CRUD operations:

```typescript
// Create a conversation
const conversation = await client.conversations.create({
  name: 'Sales Analysis',
  initial_message: 'Show me Q4 sales data',
});

// List conversations
const list = await client.conversations.list({
  limit: 10,
  sort_by: 'created_at',
});

// Get suggestions
const suggestions = await client.conversations.getSuggestions(conversation.id);
```

### Message Service

Send queries and handle AI responses:

```typescript
// Send a query
const response = await client.messages.sendQuery(conversation.id, {
  query: 'What are the top 10 customers by revenue?',
  options: {
    execute_query: true,
    generate_charts: true,
  },
});

// Process results
response.ai_message.results?.forEach(result => {
  switch (result.type) {
    case 'SQL_QUERY_STRING_RESULT':
      console.log('SQL:', result.content.sql);
      break;
    case 'CHART_GENERATION_RESULT':
      console.log('Chart:', result.content.chart_type);
      break;
  }
});
```

### Analytics Service

Track usage and performance metrics:

```typescript
// Track events
await client.analytics?.track('QUERY_EXECUTED', {
  duration: 1250,
  success: true,
});

// Get analytics summary
const summary = await client.analytics?.getSummary({
  start_date: '2024-01-01',
  end_date: '2024-12-31',
});
```

## Core Components

### Token Management

The SDK automatically handles token generation, storage, and refresh:

```typescript
// Token is automatically managed
const tokenManager = client.getTokenManager();

// Check if authenticated
const isAuth = await tokenManager.isAuthenticated();

// Manual token refresh (usually not needed)
await tokenManager.refreshToken();

// Logout
await client.logout();
```

## React Hooks

The SDK provides modern React hooks for seamless integration:

### useFigoSDK - All-in-One Hook

```tsx
import { useFigoSDK } from '@figo-ai/react-native-sdk';

function ChatScreen() {
  const sdk = useFigoSDK({
    apiKey: 'your-api-key',
    customerId: 'customer-123',
    connectionId: 'postgres-prod',
  });

  const { conversation, streaming, messages, actions } = sdk;

  // Use quick actions
  const handleSend = async (query: string) => {
    await actions.streamQuery(query);
  };

  return (
    <View>
      {streaming.isStreaming && <ActivityIndicator />}
      {streaming.results.map(result => (
        <ResultView key={result.id} result={result} />
      ))}
    </View>
  );
}
```

### Individual Hooks

- **useFigoClient**: Initialize and manage SDK client
- **useConversation**: Manage conversations with state
- **useStreaming**: Real-time streaming with progress
- **useMessages**: Message handling with caching
- **useAnalytics**: Event and performance tracking
- **useOffline**: Offline support with queue management

## UI Components

The SDK includes ready-to-use React Native components:

### FigoProvider

Context provider that wraps your app:

```tsx
<FigoProvider
  config={{
    apiKey: 'your-api-key',
    customerId: 'customer-123',
    connectionId: 'postgres-prod',
  }}
  options={{
    conversation: { autoLoad: true },
    streaming: { trackMetrics: true },
    analytics: { autoStart: true },
    offline: { autoSync: true },
  }}
  loadingComponent={<LoadingScreen />}
  errorComponent={(error) => <ErrorScreen error={error} />}
>
  <YourApp />
</FigoProvider>
```

### ChatInterface

Complete chat UI with all features:

```tsx
<ChatInterface
  showConnectionStatus
  showConversationHeader
  enableVoiceInput={false}
  enableAttachments={false}
  theme={{
    primaryColor: '#6366F1',
    backgroundColor: '#F9FAFB',
    textColor: '#111827',
  }}
  onMessageSent={(query) => console.log('Sent:', query)}
  onError={(error) => console.error(error)}
/>
```

### Individual Components

Build your own UI with granular components:

```tsx
import {
  MessageList,
  QueryInput,
  ResultViewer,
  ConnectionStatusIndicator,
  LoadingOverlay,
} from '@figo-ai/react-native-sdk';

// Custom chat screen
function CustomChat() {
  const { messages, streaming } = useFigo();
  
  return (
    <>
      <MessageList messages={messages.messages} />
      <QueryInput onSend={handleSend} />
      {streaming.isStreaming && <LoadingOverlay />}
    </>
  );
}
```

### Available Components

- **FigoProvider** - Context provider for SDK
- **ChatInterface** - Complete chat interface
- **MessageList** - Display messages with results
- **QueryInput** - Smart input with suggestions
- **ResultViewer** - Display SQL results, charts, tables
- **ChartRenderer** - Render data visualizations
- **ConnectionStatusIndicator** - Network status
- **LoadingOverlay** - Loading states
- **MessageSkeleton** - Skeleton loaders

### API Client

Make authenticated API requests:

```typescript
const apiClient = client.getApiClient();

// GET request
const response = await apiClient.get('/embed/conversations');

// POST request
const newConversation = await apiClient.post('/embed/conversation', {
  name: 'Sales Analysis',
});
```

### Error Handling

The SDK provides custom error classes for different scenarios:

```typescript
import { 
  AuthenticationError,
  RateLimitError,
  NetworkError,
  ValidationError 
} from '@figo-ai/react-native-sdk';

try {
  await client.initialize();
} catch (error) {
  if (error instanceof AuthenticationError) {
    console.error('Authentication failed:', error.message);
  } else if (error instanceof RateLimitError) {
    console.error('Rate limited. Retry after:', error.retryAfter);
  } else if (error instanceof NetworkError) {
    console.error('Network error:', error.message);
  }
}
```

### Rate Limiting

Built-in client-side rate limiting prevents hitting server limits:

```typescript
// Rate limits are automatically enforced
// Default limits:
// - Token generation: 10/hour
// - Conversations: 100/hour
// - Queries: 1000/hour
```

## Security

### Secure Storage

Sensitive data is stored securely using platform-specific solutions:
- **iOS**: Keychain Services
- **Android**: Android Keystore

### Encryption

All local data is encrypted using AES-256 encryption.
