|
|
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();
