Interval Loop Manager

A class to manage a loop with some interval.

Purpose

I want set a loop with some interval.

Sometimes, I want to stop the loop or change the interval.

How to use

Setup

Require interval-loop-manager.

const IntervalLoopManager = require('interval-loop-manager')

I explain interval loop manager by setting a loop of the following function.

const yourFunction = () => {
  // some process
}

Start a loop

In case you want to set loop with 5 seconds interval.

const managedLoop =
  new IntervalLoopManager(
    yoruFunction,
    { interval: 5000 }
  )

or

var managedLoop = new IntervalLoopManager( yourFunction )
managedLoop.start({ interval: 5000 })

Stop the loop

managedLoop.stop()

Restart the loop

managedLoop.restart()

or

managedLoop.start()

Change the interval

Ways to change the interval to 7 seconds.

In case you want to change it as soon as possible.

managedLoop.restart({ interval: 7000 })

In case you allow current loop to finish.

managedLoop.assignValues({ interval: 7000 })

Detect whether the loop is running or not

if ( managedLoop.isRunning() ) {
  console.log('Loop is running.')
} else {
  console.log('Loop is not running.')
}
