React calendar component with yearly view.

Original project found here: https://github.com/BelkaLab/react-yearly-calendar

This fork contains a few fixes:

✔ Rewritten in functional components
✔ Rewritten in TypeScript
✔ Removed moment.js dependency and replaced with day.js
✔ Added locale support
✔ Added better mobile support

$ npm install react-yearly-calendar-ts

http://belkalab.github.io/react-yearly-calendar/

Or taste an example usage below:

var ReactDOM = require('react-dom');
var {Calendar, CalendarControls} = require('react-yearly-calendar');

function onDatePicked(date) {
  alert(date);
}

ReactDOM.render(
  <Calendar
    year={2018}
    onPickDate={onDatePicked}
  />,
  document.getElementById('calendar')
);

The calendar is rendered as an html table element, to ensure proper displaying even in case the style isn't being loaded.

Take a look at the css file in examples/basic/src/style.css. Here are some head-ups if you want to style it yourself.

• table.calendar: the main element that renders the calendar
• table.calendar thead: renders the week day names
• table.calendar thead th.bolder: adds bolder class to Sundays
• table.calendar td.month-name: first column in table body, showing month names
• table.calendar td.prev-month, table.calendar td.next-month: classes applied to the days of the previous and next month showed in a month's row to fill it up. Day numbers and callbacks are present even in these cells, so we suggest to play with text color to make days less intrusive and add pointer-events: none to prevent clicking.
• table.calendar td.week-separator: class applied to table cells used to separate one week from another. As above, pointer-events: none is suggested
• table.calendar td.selected: the currently selected day
• table.calendar td.bolder: the days which are Sundays
• table.calendar td.range: the days in the selected range
• table.calendar td.range-left, table.calendar td.range-right: the left and right boundaries of the selected range

• div.calendar-controls: the main CalendarControls container
• div.calendar-controls .current-year: the current year
• div.calendar-controls .controls: applies to next and previous arrows and to today button
• div.calendar-controls .today: the today button

A first attempt at making this design responsive can be seen here (window width < 1200px triggers mobile layout). Suggestions and feedback on this are welcome on issue #10

By passing the customClasses prop, you can have a fine control on which CSS classes are assigned to each day.

• customClasses can be a function accepting a moment object as a parameter, giving back the css class to be applied to the given day.

const customClasses = day => ( day.isBefore( moment([day.year(),2,21]) ) || day.isAfter( moment([day.year(),11,21]) ) ) ? 'cheap low-season': 'expensive high-season'

• If customClasses is an object, the Calendar will use the keys as css classes and the values as rules to apply them.
  • if the value is an array of strings in the form YYYY-MM-DD, those days will be given the css class. Useful for single days, like holidays!
  • if the value is an object with a start and an end value (still in the YYYY-MM-DD form), the days in that period will be given the css class. Nice for seasons!
  • if the value is a string of comma-separated, three-letter weekdays names in the form "ddd,ddd", the class will be given to the days of the week appearing on the string. Great for closing days during the week!
  • if the value is a function returning a boolean value, the class will be assigned using the function itself as a test. A must have for the finest tuning!

Confused? see the snippet below or try it yourself with this interactive example!

const customCSSclasses = {
  holidays: [
    '2018-04-25',
    '2018-05-01',
    '2018-06-02',
    '2018-08-15',
    '2018-11-01'
  ],
  spring: {
    start: '2018-03-21',
    end: '2018-6-20'
  },
  summer: {
    start: '2018-06-21',
    end: '2018-09-22'
  },
  autumn: {
    start: '2018-09-23',
    end: '2018-12-21'
  },
  weekend: 'Sat,Sun',
  winter: day => day.isBefore( moment([2018,2,21]) ) || day.isAfter( moment([2018,11,21]))
}

Clone and run
