duration-util

A comprehensive, flexible, and efficient duration manipulation utility for JavaScript.

Inspired by the Dart programming language's Duration class, duration-util offers a similar experience for JavaScript developers, providing a rich set of functionalities to handle time durations with ease.

Install

npm install duration-util

Usage

import { Duration, setDurationTimeout, setDurationInterval, sleep } from "duration-util";

const duration = new Duration({ hours: 1, minutes: 30 });

console.log(duration.toMinutes()); //=> 90

// Using utility functions
setDurationTimeout(() => {
	console.log("Timeout after 2 minutes");
}, Duration.fromMinutes(2));

setDurationInterval(() => {
	console.log("Interval every 10 seconds");
}, Duration.fromSeconds(10));

(async () => {
	await sleep(Duration.fromSeconds(5));
	console.log("Slept for 5 seconds");
})();
