What libraries can help with rate limiting?

What libraries can help with rate limiting in my application?

There are several libraries you can use for rate limiting, such as Redis, Bucket4j, and RateLimiter in Guava. Do you have a specific programming language in mind?

I'm using Node.js. Any recommendations?

For Node.js, you might want to check out 'express-rate-limit' or 'rate-limiter-flexible'. They are both popular and easy to integrate.

How do I implement 'express-rate-limit'?

To implement 'express-rate-limit', first install it using npm. Then, you can set it up as middleware in your Express app to limit requests.

Can you provide a code example?

Sure! Here's a simple example:

const rateLimit = require('express-rate-limit');

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
});

app.use(limiter);
