(Tiny) Relative Date
Tiny function that provides relative, localised, 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'
