Moment.js Timer Plugin

The Moment.js Timer Plugin is used for the creation of timers. It is an improvement over JavaScript’s native timer. Essentially, it is a rewriting of the setInterval and setTimeout methods. It provides a list of functions concerned with creating and managing timers on top of moment duration objects.

It can be installed using the following command:

npm install moment-timer

The following are some of the lists functions in this plugin:

start
loop
duration
getDuration
getRemainingDuration
isStopped
isStarted

The below examples will help to understand some of the methods of the Timer Plugin.

Example 1:

Javascript

import moment from 'moment'; 
import timer from "moment-timer"; 
  
let start = new Date().getTime(); 
let t = new moment 
    .duration(1000) 
    .timer({ start: true }, function () { 
    console.log( 
        `Timeout Callback executed  
         ${(new Date().getTime() - start)} 
         ms after script was started.` 
    ); 
});

Output:

Timeout Callback executed 1003 ms after script was started.

Example 2:

Javascript

import moment from 'moment'; 
import timer from "moment-timer"; 
  
let t = new moment 
    .duration(10000) 
    .timer(function () { 
    console.log('Finished Timer'); 
}); 
  
t.start(); 
console.log( 
    `Before stop() is called: ${t.isStopped()}` 
); 
  
t.stop(); 
console.log( 
    `After stop() is called: ${t.isStopped()}` 
);

Output:

Before stop() is called: false
After stop() is called: true
