@mfklauberg/time v1.0.2

time

Easy and immutable time manipulation in JavaScript

Install

$ npm install @mfklauberg/time

Usage

import time, { HOURS, MINUTES, SECONDS } from '@mfklauberg/time';

// the unit will default to SECONDS
time(3600);

time(10, HOURS);

time(5, MINUTES);

time(42, SECONDS);

time('12:30', HOURS);

time('9:45', MINUTES);

time can be converted into a number.

import time, { HOURS, MINUTES, SECONDS } from '@mfklauberg/time';

const x = time(1, HOURS);

const y = time('10:30', HOURS);

const z = time('15:43', MINUTES);

// the unit will default to SECONDS
console.log(x.toNumber()); // 3600

console.log(x.toNumber(SECONDS)); // 3600

console.log(x.toNumber(MINUTES)); // 60

console.log(x.toNumber(HOURS)); // 1

console.log(y.toNumber(MINUTES)); // 630

console.log(z.toNumber(SECONDS)); // 943

From a instance of time, you can do add and subtract on it, which will result in a new time.

import time, { HOURS, MINUTES, SECONDS } from '@mfklauberg/time';

const x = time(10, HOURS);
const y = x.add(30, MINUTES);

console.log(x.toNumber(MINUTES)); // 600
console.log(y.toNumber(MINUTES)); // 630

const z = x.subtract('5:30', HOURS);

console.log(z.toNumber(MINUTES)); // 270

There's also the possibility to format a time.

import time, { HOURS, MINUTES, SECONDS } from '@mfklauberg/time';

const x = time(15, HOURS).add(30, MINUTES).add(45, SECONDS);

console.log(x.format()) // 15 hours 30 minutes 45 seconds

And also with custom labels, for both singular and plural words.

import time, { HOURS, MINUTES, SECONDS } from '@mfklauberg/time';

const x = time(15, HOURS).add(30, MINUTES).add(45, SECONDS);

const y = time(1, HOURS).add(1, MINUTES).add(1, SECONDS);

const options = {
  hour: 'hora',
  hours: 'horas',
  minute: 'minuto',
  minutes: 'minutos',
  second: 'segundo',
  seconds: 'segundos'
};

console.log(x.format(options)); // 15 horas 30 minutos 45 segundos

console.log(y.format(options)); // 1 hora 1 minuto 1 segundo
