⚙️ Configuration

Basic Configuration

const client = new AsterDEX({
  apiKey: 'your-api-key',
  apiSecret: 'your-api-secret',
  environment: 'mainnet', // 'mainnet' | 'testnet'
  timeout: 60000, // Request timeout in milliseconds
  recvWindow: 5000, // Receive window for signed requests
  enableRateLimiting: true, // Enable built-in rate limiting
  retryConfig: {
    maxRetries: 3,
    retryDelay: 1000,
    backoffMultiplier: 2
  }
});

Custom Endpoints

const client = new AsterDEX({
  baseUrl: {
    spot: 'https://custom-spot-api.example.com',
    futures: 'https://custom-futures-api.example.com',
    websocket: 'wss://custom-websocket.example.com'
  }
});

🔐 Authentication

The SDK supports all AsterDEX authentication types:

NONE - Public endpoints, no authentication required
MARKET_DATA - Market data endpoints, API key required
USER_STREAM - User data streams, API key required
TRADE - Trading endpoints, API key and signature required
USER_DATA - Account endpoints, API key and signature required

Authentication is handled automatically based on the endpoint being called.

📊 Rate Limiting

Automatic request queuing and spacing
Respect for Retry-After headers
Configurable rate limits and backoff strategies
Separate limits for different endpoint types

🌐 WebSocket Features

Subscription management with easy subscribe/unsubscribe
Combined streams support for multiple symbols
User data streams for real-time account updates
Ping/pong handling for connection health
Error recovery and connection state management
