A simple rate-limiting express middleware acoording to IP address

Install

$ npm i --save node-rate-limit

Example

const express = require('express')
const RateLimit = require('node-rate-limit')
const redis = require('redis')

const app = express()
const cache = redis.createClient()

const limiter = new RateLimit({
  max: 10, // ten times per duration
  duration: 10 * 1000, // 10 seconds
  cache: cache // redis instance
})
app.use(limiter)

Configuration

max: optional max times per duration. The default is 10.

duration: optional how long to keep the records of requests. The default is 1000 milliseconds.

cache: optional redis client instance. The default is memory cache.
