How do you set up rate limiting in an Express application?
Implement rate limiting in Express using middleware like `express-rate-limit`. Install it with `npm install express-rate-limit` and configure it to limit the number of requests from a single IP address. For example, `const limiter = rateLimit({ windowMs: 15 * 60 * 1000, max: 100 }); app.use(limiter);` limits requests to 100 per 15 minutes. This helps prevent abuse and ensure fair usage of resources.
