Installation

npm install @nivinjoseph/n-util

# or

yarn add @nivinjoseph/n-util

Quick Start

import { Duration } from '@nivinjoseph/n-util';

// Create durations in different units
const fiveMinutes = Duration.fromMinutes(5);
const twoHours = Duration.fromHours(2);
const thirtySeconds = Duration.fromSeconds(30);

// Convert between units
console.log(fiveMinutes.toSeconds()); // 300
console.log(twoHours.toMinutes()); // 120
console.log(thirtySeconds.toMilliSeconds()); // 30000
