Rate Limiting in Express: Protect Your API from Brute Force Attacks

Rate limiting is an essential feature to safeguard your API against brute force attacks. It helps control the number of requests a user can make within a specific time frame. Implementing rate limiting in an Express application is simple, thanks to the express-rate-limit package.

At first you need to install: yarn add express-rate-limit

Then create a middleware where you can limit your api request:

import rateLimit from 'express-rate-limit'



export const rateLimiter = rateLimit({

  windowMs: 60 * 1000,

  max: 100,

  message: 'You have exceeded the 100 requests in 1 min limit!',

  standardHeaders: true,

  legacyHeaders: false,

})

In this example, users are allowed up to 100 requests per minute. If they exceed this limit, they’ll receive a message stating the limit has been reached. also include rate limit info in the RateLimit-* headers and disable X-RateLimit-* headers

Then you need to add this middleware into **index file:**

import express from 'express';

import { rateLimiter } from '@/middlewares/rateLimit';



const app = express();



// Apply the rate limiter middleware to all routes

app.use(rateLimiter);



// Your other middleware and routes go here...

Conclusion

With these steps, you’ve successfully added rate limiting to your Express application. This feature helps ensure your API remains protected from abuse while maintaining a smooth experience for legitimate users.
