Client Configuration

WSX provides extensive configuration options to customize client behavior, optimize performance, and integrate with your application architecture.

Basic Configuration

HTML Configuration

Configure WSX using the wx-config attribute:

<div wx-config='{

  "debug": false,
  "reconnectInterval": 3000,
  "maxReconnectAttempts": 5,
  "timeout": 10000,
  "autoConnect": true
}'>
  <!-- WSX-enabled content -->
</div>

JavaScript Configuration

Configure WSX programmatically:

const wsx = new WSX({
  url: "ws://localhost:3000/ws",
  debug: true,
  reconnectInterval: 2000,
  maxReconnectAttempts: 10,
  timeout: 15000,

    // Add authentication token
    request.headers = request.headers || {};
    request.headers['Authorization'] = getAuthToken();
    
    // Add timestamp
    request.timestamp = Date.now();
    
    return request;
  }
}

Response Interceptors

Intercept responses before processing:

{
  responseInterceptor: (response) => {
    // Log response time
    const duration = Date.now() - response.timestamp;
    console.log(`Request took ${duration}ms`);
    
    // Handle global errors
    if (response.error) {
      showGlobalError(response.error);
    }
    
    return response;
  }
}

Custom WebSocket Options

Pass options to WebSocket constructor:

{
  websocketOptions: {
    protocols: ['wsx-protocol'],
    perMessageDeflate: true,

  logger: (level, message, data) => {
    if (level === 'error') {
      analytics.track('wsx_error', { message, data });
    }
  }
};

Dynamic Configuration

function getConfig() {
  const isProduction = process.env.NODE_ENV === 'production';
  const baseConfig = {
    debug: !isProduction,
    reconnectInterval: isProduction ? 5000 : 1000,
    maxReconnectAttempts: isProduction ? 3 : 10
  };
  
  if (isProduction) {
    return {
      ...baseConfig,
      url: "wss://api.example.com/ws",
      timeout: 15000
    };
  } else {
    return {
      ...baseConfig,
      url: "ws://localhost:3000/ws",
      timeout: 5000
    };
  }
}

const wsx = new WSX(getConfig());

Security Configuration

Authentication

{
  url: "wss://api.example.com/ws",
  headers: {
    'Authorization': `Bearer ${getAuthToken()}`
  },

    // Refresh token if needed
    if (isTokenExpired()) {
      refreshAuthToken();
    }
    return request;
  }
}

CORS Configuration

    origin: 'https://myapp.com'
  }
}

Content Security Policy

{
  // Ensure WebSocket URL is allowed in CSP
  url: "wss://api.example.com/ws",
  
  // Validate responses
  responseInterceptor: (response) => {
    if (!isValidResponse(response)) {
      throw new Error('Invalid response format');
    }
    return response;
  }
}

Performance Optimization

Connection Pooling

{
  // Enable connection pooling
  poolSize: 3,
  poolTimeout: 30000,
  
  // Load balancing
  urls: [
    "wss://api1.example.com/ws",
    "wss://api2.example.com/ws",
    "wss://api3.example.com/ws"
  ],
  loadBalancer: 'round-robin' // or 'random', 'sticky'
}

Compression

{
  // Enable compression
  compression: true,
  compressionOptions: {
    threshold: 1024,      // Compress messages > 1KB
    concurrencyLimit: 10, // Max concurrent compressions
    windowBits: 15,       // Compression window size
    memLevel: 8          // Memory level
  }
}

Batching

{
  // Batch multiple requests
  batching: true,
  batchSize: 10,        // Max requests per batch
  batchTimeout: 100,    // Max wait time (ms)
  
  // Prioritize requests
  priorityQueue: true,
  maxPriority: 10
}

Error Handling Configuration

Error Retry Strategy

{
  retryStrategy: {
    attempts: 3,
    delay: 1000,
    backoff: 'exponential', // or 'linear', 'fixed'
    maxDelay: 10000,
    jitter: true
  }
}

Global Error Handler

{
  errorHandler: (error, context) => {
    // Log error
    console.error('WSX Error:', error);
    
    // Show user notification
    if (error.type === 'connection') {
      showNotification('Connection lost. Reconnecting...', 'warning');
    } else if (error.type === 'request') {
      showNotification('Request failed. Please try again.', 'error');
    }
    
    // Track errors
    analytics.track('wsx_error', {
      type: error.type,
      message: error.message,
      context: context
    });
  }
}

Testing Configuration

Test Environment

const testConfig = {
  url: "ws://localhost:3001/ws",
  debug: true,
  timeout: 1000,
  reconnectInterval: 100,
  maxReconnectAttempts: 1,
  
  // Mock WebSocket for testing
  WebSocket: MockWebSocket,
  
  // Disable real network calls
  mockMode: true
};

Mock Configuration

{
  mockMode: true,
  mockResponses: {
    'test-action': {
      delay: 100,
      response: {
        id: 'test-id',
        target: '#test-target',
        html: '<div>Test response</div>'
      }
    }
  }
}

Framework Integration

React Integration

// React hook for WSX configuration
function useWSX(config) {
  const [wsx, setWsx] = useState(null);
  
  useEffect(() => {
    const wsxInstance = new WSX({
      ...config,
      logger: (level, message, data) => {
        if (level === 'error') {
          console.error(message, data);
        }
      }
    });
    
    setWsx(wsxInstance);
    
    return () => {
      wsxInstance.disconnect();
    };
  }, [config]);
  
  return wsx;
}

Vue Integration

// Vue plugin for WSX
const WSXPlugin = {
  install(app, options) {
    const wsx = new WSX(options);
    
    app.config.globalProperties.$wsx = wsx;
    app.provide('wsx', wsx);
  }
};

Angular Integration

// Angular service for WSX
@Injectable({
  providedIn: 'root'
})
export class WSXService {
  private wsx: WSX;
  
  constructor(@Inject('WSX_CONFIG') private config: WSXConfig) {
    this.wsx = new WSX(this.config);
  }
  
  getWSX(): WSX {
    return this.wsx;
  }
}

Configuration Validation

Schema Validation

const configSchema = {
  url: { type: 'string', required: true },
  debug: { type: 'boolean', default: false },
  timeout: { type: 'number', min: 1000, max: 60000 },
  reconnectInterval: { type: 'number', min: 100 }
};

function validateConfig(config) {
  // Validate configuration against schema
  const errors = validate(config, configSchema);
  if (errors.length > 0) {
    throw new Error(`Invalid configuration: ${errors.join(', ')}`);
  }
  return config;
}

Runtime Validation

{
  // Validate configuration at runtime
  validateConfig: true,
  
  // Custom validation function
  configValidator: (config) => {
    if (!config.url) {
      throw new Error('URL is required');
    }
    
    if (config.timeout < 1000) {
      console.warn('Timeout less than 1s may cause issues');
    }
    
    return config;
  }
}

Best Practices

Environment-Specific: Use different configurations for dev/prod
Security: Don’t expose sensitive data in client configuration
Performance: Tune timeouts and intervals based on your use case
Error Handling: Implement robust error handling and retry logic
Monitoring: Add logging and metrics for production debugging
Testing: Use mock configurations for testing
Validation: Validate configuration to catch errors early
