Smart Scheduler

Provides (easily) pause-able timeouts. This does not create multiple timeouts via setTimeout, but creates a single timeout and iterates through all submitted Timeouts to check if they have expired and run them. All Timeouts will be put into a bucket (Scheduler.DEFAULT_BUCKET_KEY if none are provided) so that Timeouts of a certain bucket can be treated independently. E.g., the user would like to treat all cache timers the same way so they are inserted into the 'cache' bucket.

Usage

npm install smart-scheduler

import { Scheduler } from "smart-scheduler";
// or
// const {Scheduler} = require('smart-scheduler');
const s = new Scheduler(10);

// note that this may run about 5ms after it is submitted since the scheduler checks for tasks every 10ms
s.add(() => {
  console.log(this);  // correct, of course, since arrow functions capture this.
  console.log("Done");
}, {timeMillis: 105});

// Be careful with this
s.add(function() {
  console.log(this) // Scheduler {} - note this is the Scheduler. Be sure to handle this case.
}, {timeMillis: 105});
// capture this
const outerThis = this;
s.add(function() {
  console.log(outerThis); // desired this.
}, {timeMillis: 105});
//  or, bind this
s.add(function() {
  console.log(this); // desired this.
}.bind(this), {timeMillis: 105});

The options are well documented in typescript here.
