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
