sandfox-timeout-scheduler

Forked off the original timeout-scheduler with some fixes and changes.

This module is a way of scheduling alot of timeouts without creating alot of timers. It still uses setTimeout underneath.

Usage

Timeouts are created/scheduled by calling schedule with a key, delay, and optionally some data.

• The key can be anything and is not limited to being a string (we're using es6 maps under the hood).
• The delay is how far in the future in milliseconds to schedule the timeout.
• The optional data can also be anything

When the timeout is reached a timeout event is emitted by the scheduler and that contains the key and any optional data for the timeout.

This module is subject to all the limitations and guarantees of the Nodejs/iojs timers module.

    var Scheduler = require('sandfox-timeout-scheduler');

    var scheduler = new Scheduler();

    scheduler.on('timeout', function(key, data) {
        // will trigger after around 2 and 3 seconds one the below items are added
    });

    scheduler.schedule('key1', 2000);
    scheduler.schedule('key2', 3000, {foo: 'bar'}); // optionally attach data to the scheduled timeout
    scheduler.schedule('key3', 4000);

    scheduler.cancel('key3');

    schedule.has('key1'); // true

    schedule.has('key3'); // false
