Vanilla JS Datepicker

A vanilla JavaScript remake of bootstrap-datepicker for Bulma and other CSS frameworks

This package is written from scratch as ECMAScript modules/Sass stylesheets to reproduce similar usability to bootstrap-datepicker.
It can work either standalone or with CSS framework (e.g. Bootstrap, Foundation), but works best with Bulma as it's developed primarily for Bulma.

The package also includes pre-built js/css files for those who like to use it directly on browser.

Features

Date picker (input-dropdown, inline), date range picker
Keyboard operation support (navigation by arrow keys, editing on input field)
i18n support (locales, CSS-based text direction detection)
Easily customizable to adapt stylesheet for various CSS frameworks
Dependency free
Made for modern browsers — no IE support
Lightweight (well, relatively…) — 33kB (minified, uncompressed)

Quick Start

Install the package using npm.

npm install --save-dev vanillajs-datepicker

Date picker

– Input picker

create a text input element.

<input type="text" name="foo">

import the Datepicker module.

import Datepicker from 'path/to/node_modules/vanillajs-datepicker/js/Datepicker.js';

Or if you use a bundler that supports pkg.module (e.g. Rollup with node-resolve plugin, webpack)

import { Datepicker } from 'vanillajs-datepicker';

_Or if your bundler supports package entry points (e.g. Rollup with node-resolve plugin v8.4+, webpack v5+), you can also do this._

import Datepicker from 'vanillajs-datepicker/Datepicker';

call Datepicker constructor with the input element and, optionally, config options.

const elem = document.querySelector('input[name="foo"]');
const datepicker = new Datepicker(elem, {
  // ...options
});

– Inline picker

create a block element.

<div id="foo" data-date="01/25/2020"></div>

import the Datepicker module in the same way as Input picker.
call Datepicker constructor with the block element and, optionally, config options.

const elem = document.getElementById('foo');
const datepicker = new Datepicker(elem, {
  // ...options
});

Date range picker

create a block element that contains 2 text input elements.

<div id="foo">
  <input type="text" name="start">
  <span>to</span>
  <input type="text" name="end">  
</div>

import the DateRangePicker module.

import DateRangePicker from 'path/to/node_modules/vanillajs-datepicker/js/DateRangePicker.js';

Or if you use a bundler that supports pkg.module (e.g. Rollup with node-resolve plugin, webpack)

import { DateRangePicker } from 'vanillajs-datepicker';

_Or if your bundler supports package entry points (e.g. Rollup with node-resolve plugin v8.4+, webpack v5+), you can also do this._

import DateRangePicker from 'vanillajs-datepicker/DateRangePicker';

call DateRangePicker constructor with the block element and, optionally, config options.

const elem = document.getElementById('foo');
const rangepicker = new DateRangePicker(elem, {
  // ...options
});

Stylesheet

import scss file.

@import 'path/to/node_modules/vanillajs-datepicker/sass/datepicker';

Using with CSS framework

Bulma

import scss file for Bulma instead.

@import 'path/to/node_modules/vanillajs-datepicker/sass/datepicker-bulma';

Bootstrap

use buttonClass: 'btn' option to call Datepicker/DateRangePicker constructor.

const datepicker = new Datepicker(elem, {
  buttonClass: 'btn',
});

import scss file for Bootstrap instead.

@import 'path/to/node_modules/vanillajs-datepicker/sass/datepicker-bs4';

Foundation

import scss file for Foundation instead.

@import 'path/to/node_modules/vanillajs-datepicker/sass/datepicker-foundation';

Other frameworks

If the framework uses a specific class for button elements, set it to the buttonClass option to call Datepicker/DateRangePicker constructor.

const datepicker = new Datepicker(elem, {
  buttonClass: 'uk-button',
});

Copy the following template into your sass stylesheet, and edit the node_module path, the variables, button class and button style adjustments to match your environment.

/***
 Copy the datepicker variables (the ones with `dp-` prefix and `!default` flag)
 from `sass/Datepicker.scss` to here
 Then, edit them using your framework's variables/values
 e.g.:
 $dp-background-color: $background !default;
 $dp-border-color: $border !default;
 ...
 ***/

@import '../node_modules/vanillajs-datepicker/sass/mixins';

@mixin dp-button {
  .button {
    /***
     Place style adjustment for date picker's buttons here, if needed
     ***/

    .datepicker-header & {
      @include dp-header-button-common;

      /***
       Place style adjustment specific to the header buttons here, if needed
       ***/
    }

    .datepicker-footer & {
      @include dp-footer-button-common;

      /***
       Place style adjustment specific to the footer buttons here, if needed
       ***/
    }
  }
}

@import '../node_modules/vanillajs-datepicker/sass/datepicker';

Using from Browser

From CDN, load css and js files.

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/vanillajs-datepicker@1.1.4/dist/css/datepicker.min.css">

...

<script src="https://cdn.jsdelivr.net/npm/vanillajs-datepicker@1.1.4/dist/js/datepicker-full.min.js"></script>

If you use Bulma, Bootstrap or Foundation, you can use the css for your framework instead.

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/vanillajs-datepicker@1.1.4/dist/css/datepicker-bulma.min.css">
<!-- or -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/vanillajs-datepicker@1.1.4/dist/css/datepicker-bs4.min.css">
<!-- or -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/vanillajs-datepicker@1.1.4/dist/css/datepicker-foundation.min.css">

And if don't need date range, you can use the datepicker-only version of js file.

<script src="https://cdn.jsdelivr.net/npm/vanillajs-datepicker@1.1.4/dist/js/datepicker.min.js"></script>

Call Datepicker/DateRangePicker constructor in the same way as explained above. (The classes are exposed to global scope.)

const elem = document.querySelector('input[name="foo"]');
const datepicker = new Datepicker(elem, {
  // ...options
});
