Error Handling Strategies

Basic Error Handler

function handleError(error) {
  switch (error.code) {
    case 13009:
      // Token expired - refresh
      return refreshToken();
    
    case 10002:
      // Insufficient funds
      throw new Error('Insufficient funds for this operation');
    
    case 10029:
      // Rate limit - retry with backoff
      return retryWithBackoff();
    
    case 11006:
      // Post-only rejected
      console.log('Order would have taken liquidity');
      return null;
    
    default:
      throw new Error(`API Error ${error.code}: ${error.message}`);
  }
}

Retry Logic

async function retryWithBackoff(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (error.code === 10029) {
        // Rate limit - exponential backoff
        const delay = Math.pow(2, i) * 1000;
        console.log(`Rate limited, retrying in ${delay}ms`);
        await sleep(delay);
        continue;
      }
      
      if (error.code === 13009) {
        // Token expired - refresh and retry
        await refreshToken();
        continue;
      }
      
      // Other errors - don't retry
      throw error;
    }
  }
  
  throw new Error('Max retries exceeded');
}

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

Error Recovery

class ErrorRecovery {
  constructor(apiClient) {
    this.apiClient = apiClient;
    this.maxRetries = 3;
  }

  async executeWithRecovery(fn) {
    let lastError;
    
    for (let attempt = 0; attempt < this.maxRetries; attempt++) {
      try {
        return await fn();
      } catch (error) {
        lastError = error;
        
        const shouldRetry = await this.handleError(error, attempt);
        if (!shouldRetry) {
          throw error;
        }
      }
    }
    
    throw lastError;
  }

  async handleError(error, attempt) {
    switch (error.code) {
      case 13009: // Token expired
        await this.apiClient.refreshToken();
        return true;
      
      case 10029: // Rate limit
        const delay = Math.pow(2, attempt) * 1000;
        await sleep(delay);
        return true;
      
      case 10002: // Insufficient funds
        console.error('Insufficient funds - cannot retry');
        return false;
      
      case 11000: // Order not found
        console.warn('Order not found - may have been filled');
        return false;
      
      default:
        // Unknown error - don't retry
        return false;
    }
  }
}

// Usage
const recovery = new ErrorRecovery(apiClient);

try {
  const result = await recovery.executeWithRecovery(async () => {
    return await apiClient.placeOrder({
      instrument_name: 'BTC-PERPETUAL',
      amount: 10,
      price: 50000
    });
  });
  console.log('Order placed:', result);
} catch (error) {
  console.error('Failed after retries:', error);
}

Error Monitoring

Error Logger

class ErrorLogger {
  constructor() {
    this.errors = [];
  }

  log(error, context = {}) {
    this.errors.push({
      code: error.code,
      message: error.message,
      data: error.data,
      context,
      timestamp: Date.now()
    });
    
    // Alert on critical errors
    if (this.isCritical(error)) {
      this.alert(error);
    }
  }

  isCritical(error) {
    const criticalCodes = [10002, 11008]; // Insufficient funds, max position
    return criticalCodes.includes(error.code);
  }

  alert(error) {
    console.error('CRITICAL ERROR:', error);
    // Send to monitoring service
  }

  getStats() {
    const errorCounts = {};
    this.errors.forEach(err => {
      errorCounts[err.code] = (errorCounts[err.code] || 0) + 1;
    });
    
    return {
      total: this.errors.length,
      byCode: errorCounts,
      recent: this.errors.slice(-10)
    };
  }
}

Error Metrics

class ErrorMetrics {
  constructor() {
    this.metrics = {
      total: 0,
      byCode: {},
      byMethod: {},
      lastHour: []
    };
  }

  record(error, method) {
    this.metrics.total++;
    
    // Count by error code
    this.metrics.byCode[error.code] = 
      (this.metrics.byCode[error.code] || 0) + 1;
    
    // Count by method
    this.metrics.byMethod[method] = 
      (this.metrics.byMethod[method] || 0) + 1;
    
    // Track recent errors
    this.metrics.lastHour.push({
      code: error.code,
      method,
      timestamp: Date.now()
    });
    
    // Clean old errors
    this.cleanOldErrors();
  }

  cleanOldErrors() {
    const oneHourAgo = Date.now() - 3600000;
    this.metrics.lastHour = this.metrics.lastHour.filter(
      err => err.timestamp > oneHourAgo
    );
  }

  getErrorRate() {
    return this.metrics.lastHour.length / 3600; // errors per second
  }

  getMostCommonErrors(limit = 5) {
    return Object.entries(this.metrics.byCode)
      .sort((a, b) => b[1] - a[1])
      .slice(0, limit)
      .map(([code, count]) => ({ code: parseInt(code), count }));
  }
}

Validation Errors

Parameter Validation

function validateOrderParams(params) {
  const errors = [];

  // Required fields
  if (!params.instrument_name) {
    errors.push({
      code: 10009,
      message: 'invalid_argument',
      param: 'instrument_name'
    });
  }

  if (!params.amount || params.amount <= 0) {
    errors.push({
      code: 10009,
      message: 'invalid_argument',
      param: 'amount'
    });
  }

  // Type validation
  if (params.type === 'limit' && !params.price) {
    errors.push({
      code: 10009,
      message: 'invalid_argument',
      param: 'price',
      reason: 'price required for limit orders'
    });
  }

  return errors;
}

// Usage
const errors = validateOrderParams(orderParams);
if (errors.length > 0) {
  throw new Error(`Validation failed: ${JSON.stringify(errors)}`);
}

Complete Error Handler

class DeribitErrorHandler {
  constructor(apiClient) {
    this.apiClient = apiClient;
    this.logger = new ErrorLogger();
    this.metrics = new ErrorMetrics();
  }

  async handle(error, context = {}) {
    // Log error
    this.logger.log(error, context);
    this.metrics.record(error, context.method);

    // Handle specific errors
    switch (error.code) {
      case 13009:
        return this.handleTokenExpired();
      
      case 10029:
        return this.handleRateLimit(context.attempt || 0);
      
      case 10002:
        return this.handleInsufficientFunds(error);
      
      case 11006:
        return this.handlePostOnlyReject(context);
      
      default:
        return this.handleGenericError(error);
    }
  }

  async handleTokenExpired() {
    console.log('Token expired, refreshing...');
    await this.apiClient.refreshToken();
    return { retry: true };
  }

  async handleRateLimit(attempt) {
    const delay = Math.min(Math.pow(2, attempt) * 1000, 30000);
    console.log(`Rate limited, waiting ${delay}ms`);
    await sleep(delay);
    return { retry: true, delay };
  }

  handleInsufficientFunds(error) {
    console.error('Insufficient funds:', error.data);
    return { retry: false, fatal: true };
  }

  handlePostOnlyReject(context) {
    console.log('Post-only order would take liquidity');
    return { retry: false, adjustPrice: true };
  }

  handleGenericError(error) {
    console.error(`API Error ${error.code}: ${error.message}`);
    return { retry: false };
  }

  getMetrics() {
    return {
      logger: this.logger.getStats(),
      metrics: {
        total: this.metrics.metrics.total,
        errorRate: this.metrics.getErrorRate(),
        mostCommon: this.metrics.getMostCommonErrors()
      }
    };
  }
}

// Usage
const errorHandler = new DeribitErrorHandler(apiClient);

try {
  const result = await apiClient.placeOrder(params);
} catch (error) {
  const action = await errorHandler.handle(error, {
    method: 'private/buy',
    params
  });
  
  if (action.retry) {
    // Retry the operation
  } else if (action.fatal) {
    // Stop and alert
  }
}

Best Practices

1. Always Check for Errors

const response = await apiCall();
if (response.error) {
  handleError(response.error);
}

2. Implement Exponential Backoff

async function withBackoff(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await sleep(Math.pow(2, i) * 1000);
    }
  }
}

3. Log All Errors

function logError(error, context) {
  console.error({
    code: error.code,
    message: error.message,
    context,
    timestamp: new Date().toISOString()
  });
}

4. Monitor Error Rates

if (errorMetrics.getErrorRate() > 1) {
  console.warn('High error rate detected');
  // Alert or throttle requests
}
