express-rate-limiter-middleware is a middleware for Express.js applications that provides rate limiting functionality to control the number of requests a client can make to the server within a specified time frame.
You can install express-rate-limiter-middleware via npm:
npm install express-rate-limiter-middlewareTo use express-rate-limiter-middleware in your Express.js application, follow these steps:
- Import the required modules:
const express = require('express');
const redis = require('redis');
const { RateLimit } = require('express-rate-limit');
const { RedisStore } = require('rate-limit-redis');- Create an Express app and specify the port:
const app = express();
const port = process.env.PORT || 3000;- Create a Redis client:
const redisClient = redis.createClient();- Set up the rate limiter middleware:
const limiter = new RateLimit({
store: new RedisStore({
client: redisClient
}),
windowMs: 1 * 60 * 1000, // 1 minute
max: 100, // limit each IP to 100 requests per windowMs
message: "Too many requests, please try again later."
});
// Apply rate limiter to all routes
app.use(limiter);- Define your routes as usual:
app.get('/', (req, res) => {
res.send('Hello World!');
});- Start the server:
app.listen(port, () => {
console.log(`Server is running on port ${port}`);
