Rolling Rate Limiter with Redis

Rolling Rate Limiter is a module for Node.js which provides a basic, but a solid rate limiter using sliding windows stored in Redis. It was inspired from ClassDojo Rate Limiter, but several issues has been fixed like :

Removing closure to fix a memory leak if a lot of users request the limit
Instead of fetching the whole range (with ZRANGE(key, 0, -1)) and then count the number of elements, we use ZCARD, and only fetch the first timestamp and the last timestamp, so we avoid a large operation in Redis and save a lot of memory if we use a large limit (like 3000 request / min).
Fixing a bug with interval in microseconds instead of milliseconds
Avoid a race condition with ZREM and ZADD

Requirements

NodeJS >= 0.10.x
Redis >= 2.6.12

Examples

1var RateLimiter = require("redis-ratelimit");
2var redis = require('ioredis'); // or node_redis or any Redis Client
3
4var client = redis.createClient({
5  port: 6379,
6  host: '127.0.0.1'
7});
8
9var limiter = RateLimiter({
10  redis: client, 
11  namespace: "my-limiter", // optional
12  interval: 1000, // in miliseconds (= 1s)
13  maxInInterval: 10, // 10 actions max
14  minDifference: 100 // optional: the minimum time (in miliseconds) between any two actions
15});
16
17client.on('ready', function() {
18 limiter('my-limit', function(err, timeLeft) {
19  if(err) {
20    throw err;
21  }
22  
23  // timeLeft is in ms
24  if(timeLeft > 0) {
25    console.log('Rate limit exceeded, Please wait %s secs', timeLeft/1000);
26  } else {
27    // Do your stuff
28  }
29  
30 });
31});
