Getting Started

Installation

You can install it using npm or yarn:

npm install vanilla-calendar-pro
# or
yarn add vanilla-calendar-pro

Usage

Here's a simple example of using it in your HTML:

  
  
  
    <div id="calendar"></div>
    
    
  

To add the necessary styles and scripts, you can use the following code:

import { Calendar } from 'vanilla-calendar-pro';
import 'vanilla-calendar-pro/styles/index.css';

// Initialize the calendar
const calendar = new Calendar('#calendar');
calendar.init();
// or
// const calendarWithInput = new Calendar('#calendar-input', { inputMode: true });
// calendarWithInput.init();

CSS Styles

// Only layout calendar
import 'vanilla-calendar-pro/styles/layout.css';

// Themes
import 'vanilla-calendar-pro/styles/themes/light.css';
import 'vanilla-calendar-pro/styles/themes/dark.css';
// ...and others

The calendar can automatically switch between a light or dark theme depending on the user's system settings, or track a custom HTML attribute that specifies the desired theme.

• The index.css file contains all the styles from the layout.css file, as well as the light and dark theme styles.
• The layout.css file contains the essential structural styles for the calendar.
• The themes/light.min.css theme provides a light color scheme.
• The themes/dark.min.css theme offers a dark color scheme.
• ...and others

If you want to apply a specific theme, it is recommended to import layout.css along with your preferred theme instead of index.css.

Layouts

VanillaCalendar features customizable DOM templates that allow you to modify the structure of the calendar to fit your needs. The templates are identified by tags containing the # character, and they should include a trailing slash at the end.

The calendar contains custom layouts for each calendar type, which allow you to change the calendar structure to suit your needs. Each layout contains its own set of components that can be moved or removed from it if necessary. By default, a layout contains all the components available to it. Components are identified by tags containing the # character, and they must contain a slash at the end of the tag.

Here is an example of the default layout:

new Calendar('#calendar', {
  layouts: {
    default: `
      <div aria-label="Calendar Navigation" role="toolbar" data-vc="header" class="vc-header">
        &lt;#ArrowPrev [month] /&gt;
        <div data-vc-header="content" class="vc-header__content">
          &lt;#Month /&gt;
          &lt;#Year /&gt;
        </div>
        &lt;#ArrowNext [month] /&gt;
      </div>
      <div data-vc="wrapper" class="vc-wrapper">
        &lt;#WeekNumbers /&gt;
        <div data-vc="content" class="vc-content">
          &lt;#Week /&gt;
          &lt;#Dates /&gt;
          &lt;#DateRangeTooltip /&gt;
        </div>
      </div>
      &lt;#ControlTime /&gt;
    `
  }
});
