Usage

esm or Typescript

import { parse, format, prettyFormat, date, relativeTime, Formatter } from '@imranbarbhuiya/duration';

CommonJS

const { parse, format, prettyFormat, date, relativeTime, Formatter } = require('@imranbarbhuiya/duration');

parse

// string => number
parse('1s 1min 1h 1d 1w 1mo 1y'); // 34844461001
parse('2 days'); //=> 172800000
parse('1d'); //=> 86400000
parse('-3 days'); //=> -259200000

format

// number => string
format(2 * 60000); //=> 2m
format(-3 * 60000, { long: true }); //=> -3 minutes
format(parse('10 hours'), { long: true }); //=> 10 hours

prettyFormat

// number to string (multiple units)
prettyFormat(60000); //=> 1 minute
prettyFormat(121000); //=> 2 minutes, 1 second
prettyFormat(1000 * 60 * 60 * 60 * 24 * 30, { format: 'short' }); //=> 1mo
prettyFormat(86406010, {
    format: 'short',
    patterns: ['hour', 'minute', 'second', 'millisecond'],
    separator: ' '
}); //=> 24h 6s 10ms

Writing these patterns every time is a pain. That's why there is a Formatter class which can be used to format multiple times without repeating yourself.

Formatter

const formatter = new Formatter({
    format: 'short',
    patterns: ['hour', 'minute', 'second', 'millisecond'],
    separator: ' '
});

formatter.format(1000 * 60 * 60 * 24 * 30); //=> 720h
formatter.format(86406010); //=> 24h 6s 10ms

date

// format a date
date('2022-01-01', 'YYYY-MMM-Do'); //=> 2022-Jan-Saturday
date('2022-01-01T00:00:00.000Z', 'yyyy-MM-D HH:mm:ss.SS Z'); //=> 2022-01-1 00:00:00.00 0
date('2022-01-01T00:00:00.000Z', 'yyyy-MMMM-DDD HH:mm:ss.SS'); //=> 2022-January-Sat 00:00:00.00

relativeTime

// format a date as relative date
relativeTime(Date.now() + 1000); //=> in a few seconds
relativeTime(Date.now() - 1000 * 60 * 60); //=> an hour ago
