Relative Date

Tiny function that provides relative, human-readable dates.

Installation

npm install tiny-relative-date

Usage

The module returns a relativeDate function with English translations by default.

const relativeDate = require('tiny-relative-date')

The relativeDate function accepts date strings or Date objects.

relativeDate('2017-06-25 09:00') // '12 hours ago'
relativeDate(new Date()) // 'just now'

The value of "now" can also be passed as a second parameter.

const now = new Date('2017-06-25 08:00:00')
const date = new Date('2017-06-25 07:00:00')

relativeDate(date, now) // 'an hour ago'

Using a non-English locale

The tiny-relative-date module can be initialised with a locale. See the translations directory for a list of available locales.

const relativeDateFactory = require('tiny-relative-date/lib/factory')
const deTranslations = require('tiny-relative-date/translations/de')
const relativeDate = relativeDateFactory(deTranslations)

relativeDate(new Date()) // 'gerade eben'

Using a custom locale

You can also use a completely custom locale by passing a translations object instead of a locale string. Translations can be plain strings with a {{time}} placeholder, or they can be functions. See the Adding new locales section below for a list of translation keys.

const relativeDateFactory = require('tiny-relative-date/lib/factory')
const relativeDate = relativeDateFactory({
  hoursAgo: '{{time}}h ago',
  daysAgo: (days) => `${days * 24}h ago`
})

relativeDate('2017-06-25 07:00:00') // '2h ago'
relativeDate('2017-06-24 06:00:00') // '27h ago'
