📈 Performance Optimization

Monitoring-Driven Optimization

Performance Analysis

• Identify Bottlenecks: Use metrics to find slow operations
• Resource Optimization: Monitor resource usage patterns
• Capacity Planning: Use trends to plan for growth

Optimization Strategies

// Performance monitoring middleware
const performanceMonitor = (req: Request, res: Response, next: NextFunction) => {
  const start = Date.now();
  
  res.on('finish', () => {
    const duration = Date.now() - start;
    
    if (duration > 5000) {
      logger.warn('Slow request detected', {
        method: req.method,
        path: req.path,
        duration
      });
    }
  });
  
  next();
};

// Caching middleware
const cacheMiddleware = (ttlMs = 300000) => {
  const cache = new Map();
  
  return (req: Request, res: Response, next: NextFunction) => {
    const key = `${req.method}:${req.path}:${JSON.stringify(req.query)}`;
    const cached = cache.get(key);
    
    if (cached && Date.now() - cached.timestamp < ttlMs) {
      return res.json(cached.data);
    }
    
    const originalSend = res.json;
    res.json = function(data) {
      cache.set(key, { data, timestamp: Date.now() });
      return originalSend.call(this, data);
    };
    
    next();
  };
};
