📈 Performance Optimization
Monitoring-Driven Optimization
Performance Analysis

- 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();
};
};
