Simple Multilingual Calendar Component With Vanilla JavaScript

Preview:

Description:

A tiny clean calendar in Vanilla JavaScript. Create a beautiful customizable calendar for your website, using the ISO 8601 standard. No dependencies, no jQuery, and no frameworks.

Key features include custom holidays, multiple date selection, inbuilt language support, and minified size of only 9kb.

The code is easy to understand and is a good starting point if you want to display events and schedules on the page.

How to use it:

1. Install and import the VanillaCalendar component.

# NPM
$ npm i @uvarov.frontend/vanilla-calendar

import VanillaCalendar from '@uvarov.frontend/vanilla-calendar';

2. Or load the JavaScript library directly in the document.

<link rel="stylesheet" href="build/vanilla-calendar.min.css" />
<script src="build/vanilla-calendar.min.js"></script>

3. Add the CSS class ‘vanilla-calendar’ to the target container where the library generates the calendar.

<div class="vanilla-calendar">
  
</div>

4. Generate a basic calendar.

const calendar = new VanillaCalendar('#vanilla-calendar', {
      // Options
});
calendar.init();

5. Set the calendar type: ‘default’ | ‘multiple’ | ‘month’ | ‘year’.

const calendar = new VanillaCalendar('#vanilla-calendar', {
      type: 'multiple',
});

6. Specify the number of months to display if the calendar type is defined as “multiple”. Default: 2.

const calendar = new VanillaCalendar('#vanilla-calendar', {
      months: 2,
});

7. Date configs.

const calendar = new VanillaCalendar('#vanilla-calendar', {
      date: {
        min: '1970-01-01',
        max: '2470-12-31',
        today: new Date('2022-01-07'),
      },
});

8. Determine whether to use ISO 8601 format. (Default: true,)

const calendar = new VanillaCalendar('#vanilla-calendar', {
      settings: {
        iso8601: false,
      },
});

9. Date range configs.

const calendar = new VanillaCalendar('#vanilla-calendar', {
      settings: {
        range: {
          min: '2022-05-01',
          max: '2022-05-13',
          disablePast: false, 
          disableGaps: false,
          disableWeekday: false,
          disabled: [], // disabled dates
          enabled: [], // disabled dates
        },
      },
});

10. Date selection configs.

const calendar = new VanillaCalendar('#vanilla-calendar', {
      settings: {
        selected: {
          dates: ['2022-05-01', '2022-05-02', '2022-05-03', '2022-05-04'],
          time: '03:44 AM',
          month: 5,
          year: 2022,
          holidays: ['2022-12-24', '2022-12-25'],
        },
        selection: {
          day: 'single', // 'single' | 'multiple' | 'multiple-ranged'
          month: true,
          year: true,
          time: false,
          controlTime: 'all', // 'all' | 'range'
          stepHours: 1,
          stepMinutes: 1,
        },
      },
});

11. Set the visibility of the calendar.

const calendar = new VanillaCalendar('#vanilla-calendar', {
      settings: {
        visibility: {
         // hightlights weekends
         weekend: true,
         // highlights today
         today: true,
         // abbreviated names of months in the month selection
         monthShort: true,
         // show week numbers of the year
         weekNumbers: false,
         // show all days, including disabled ones.s
         disabled: false,
         // show the days of the past and next month.
         daysOutside: true,
        },
      },
});

12. Set the language of the calendar.

const calendar = new VanillaCalendar('#vanilla-calendar', {
      settings: {
        lang: 'en',
      },
});

// OR
const calendar = new VanillaCalendar('#vanilla-calendar', {
      settings: {
        lang: 'define',
      },
      locale: {
        months: ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'],
        weekday: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'],
      },
});

13. Change the default DOM templates.

new VanillaCalendar('#calendar', {
    DOMTemplates: {
      default: `
        <div class="vanilla-calendar-header">
          <#ArrowPrev />
          <div class="vanilla-calendar-header__content">
            <#Month />
            <#Year />
          </div>
          <#ArrowNext />
        </div>
        <div class="vanilla-calendar-wrapper">
          <#WeekNumbers />
          <div class="vanilla-calendar-content">
            <#Week />
            <#Days />
          </div>
        </div>
        <#ControlTime />
      `
    }
});

// default month selection template
const calendar = new VanillaCalendar('#vanilla-calendar', {
      DOMTemplates: {
        month: `
          <div class="vanilla-calendar-header">
            <div class="vanilla-calendar-header__content">
              <#Month />
              <#Year />
            </div>
          </div>
          <div class="vanilla-calendar-wrapper">
            <div class="vanilla-calendar-content">
              <#Months />
            </div>
          </div>
        `
      }
});

14. Available events.

const calendar = new VanillaCalendar('#vanilla-calendar', {
      actions: {
        clickDay(event, dates) {},
        clickWeekNumber(event, number, days, year) {},
        clickMonth(e, month) {},
        clickYear(event, year) {},
        clickArrow(event, year, month) {},
        changeTime(event, time, hours, minutes, keeping) {},
      },
});

15. Config the hover-triggered popup.

      popups: {
        '2022-06-28': {
          modifier: 'bg-red',
          html: 'Meeting at 9:00 PM',
