    Redis TokenThrottle

    NPM

    A Redis-backed implementation of tokenthrottle

    Simply wraps tokenthrottle with a Redis back-end, so you can use it across multiple servers/processes.

    // Create a redis client 
    var redisClient = require("redis").createClient()
     
    // Create a throttle with 100 access limit per second. 
    var throttle = require("tokenthrottle-redis")({rate: 100, expiry: 86400}, redisClient)
     
    // in some_function that you want to rate limit 
      throttle.rateLimit(id, function (err, limited) {
        /* ... handle err ... */
        if (limited) {
          return res.next(new Error("Rate limit exceeded, please slow down."));
        }
        else {
          /* ... do work ... */
        }
      })
     

    Options

    Accepts all of the same options as tokenthrottle, plus two extra:

    • expiry: {Number} Number of seconds after which untouched tokens will be expired, to save memory in Redis. (defaults to no expiry)
    • prefix: {String} An optional string to prefix throttle keys with in redis, default is "redisThrottle"
