Ensure that a series of functions are called with a minimum interval between each invocation.
npm install rate-limitEnsure that a series of functions are called with a minimum interval between each invocation.
npm install rate-limit
Call rateLimit.createQueue(options) to create a queue,
where the interval between function calls is specified in milliseconds by options.interval.
Add a function to be called by calling queue.add(func).
For instance:
``javascript
var rateLimit = require("rate-limit");
function getNow() {
return new Date().getTime();
}
var startTime = getNow();
function printElapsedTime() {
console.log(getNow() - startTime);
}
var queue = rateLimit.createQueue({interval: 100});
queue.add(printElapsedTime);
queue.add(printElapsedTime);
queue.add(printElapsedTime);
// Sample output:
// 0
// 105
// 206
