@mailbutler/dayjs-plugins

A set of utility and formatting plugins for Dayjs.

Getting Started

Prerequisites

The plugins in this package depends on the following dayjs plugins:

• calendar
• localizedFormat

You also need to import the following locales before registering the plugin:

• de
• en
• fr

You need to import those dependencies before you import the plugins from this package.

Installation

With npm (or yarn)

$ npm install --save @mailbutler/dayjs-plugins
$ # Or
$ yarn add @mailbutler/dayjs-plugins

With a CDN

Dayjs must be available as a global object so you will need to import it from a CDN too, we use unpkg here as an example.

<script src="https://unpkg.com/dayjs@1.8.15/dayjs.min.js"></script>
<script src="https://unpkg.com/@mailbutler/dayjs-plugins@0.1.0/dist/dayjs-plugin-mailbutler-calendar.min.js"></script>

Quick start

If you are using a bundler, like webpack or rollup you'll just need to require the lib.

If you are using a CDN, the lib will be available under window.dayjsPluginMailbutlerCalendar.

const dayjs = require('dayjs')
const localizedFormat = require('dayjs/plugin/localizedFormat');
const calendar = require('dayjs/plugin/calendar');
const { relative, calendarLocalization } = require('@mailbutler/dayjs-plugins')

// import required translation files
require('dayjs/locale/de')
require('dayjs/locale/en')
require('dayjs/locale/fr')

// register required plugins
dayjs.extends(localizedFormat)
dayjs.extends(calendar)

// register the plugins
dayjs.extends(calendarLocalization)
dayjs.extends(relative)

The calendarLocalization plugin

Depends on calendar and localizedFormat plugins.

Adds localized formatting for the calendar for the folllowing languages:

• en
• de
• fr

When using calendar with one of these languages, the output string will be localized.

Example:

const localized = dayjs('2019-05-01').calendar();

The relative plugin

Depends on the calendarLocalization plugin.

adds two new methods to the dayjs instance.

• relative allows the user to format the date relatively to another date.
• relativeNow allows the user to format the date relatively to the current date.

Example:

// relative
dayjs('2018-12-12').relative(dayjs('2018-12-25'))
dayjs('2018-12-12').relativeNow()
