simple-task-scheduler

Schedular

A scheduler is a component that allows you to schedule tasks that will be executed in the future.

NOTE: reschedule should use the same timing format as the task when initialized - (i.e : recurrent tasks will be reschedule to different recurrent interval... So its use only to change the period of the time).

Installation

You can install using npm.

npm install simple-task-scheduler

Usage

const Scheduler = require('simple-task-scheduler')
 
const fn = () => {
  console.log(new Date())
}
const period = {
  years: 0,
  months: 0,
  weeks: 0,
  days: 0,
  hours: 0,

Scheduler.doRecurrentCron(fn, '3 * * * * *')
 
const recurrentTask = Scheduler.doRecurrent(fn, { days: 14 })
Scheduler.reschedule(recurrentTask, { days: 21 })
Scheduler.stop(recurrentTask)
 
Scheduler.stopAll()
