q-ratelimit

Rate limiting (throttling) implementation for Q promises on Node.js

Install: npm install q-ratelimit

Limit frequency of promise fulfilling:

var throttle = require('q-ratelimit')(2000); /* rateInMilliseconds */
 
var startTime = Date.now();
 
for (var i = 0; i < 10; i++) {
    throttle().then(function() { console.log(Date.now() - startTime); }).done();
}
 
// example output:
// 11
// 2007
// 4007
// 6008
// 8011
// 10014
// 12016
// 14018
// 16020
