About

The package

Kaalendar is a TypeScript library that works with 0 dependency. It was made for help to manage calendars generation/creation and datepickers.

Me

I had initially made this code for a personnel project that uses calendars but as a citation that I really like say:

"All we have to decide is what to do with the time that is given us." J. R. R. Tolkien

So that is why I decided to use mine to publish Kaalendarjs which is my first public package for the wonderful world of Open Source & JavaScript.

In the future

I will add more features to the package in the futur like:

• The possibility to provide a public holiday list
• The possibility to disable the weekend days
• Add hours:
  • Add working hours
  • Splitting the day on working hours
• Others ?

Installation

Installation from npm

See npm documentation on how to get started with npm.

Instanciation

You can instanciate a new Kaalendar using its class:

Instanciation without any parameters:

import Kaalendar from 'kaalendar';

const kaalendar = new Kaalendar();

If you create the kaalendar like this, it will be instanciate with Date.now and use the current year and month as default.

Instanciation with parameters:

1. The year
2. The month
3. The language
4. An enum of the days of the week so you can start the week by the day of you choice (monday to sunday)
5. An option object to provide optionnal parameters (available options are listed in the interface in Kaalendar file)

import Kaalendar from 'kaalendar';
import { DaysOfWeek } from 'kaalendar/utils/utils';

const kaalendar = new Kaalendar(2022, 7, 'en', DaysOfWeek.SUNDAY, {
  generateOnlyDaysOfCurrentMonth: false,
  generateASingleArray: false,
});

Methods

The kaalendar class provides a bunch of methods and features:

Navigation:

The class provides methods to navigate through the calendar

  Description:

  This method will return either a singleArray of days of the current month or a 2D array AND either the last days of the previous month + first days of the next month or not, depending on the options passed while instanciation:

  • generateASingleArray: boolean
  • generateOnlyDaysOfCurrentMonth: boolean

  👉 kaalendar.generateArray()

• Iterator()

  You can use iterable features on your kaalendar object to get all month of the current year. This to avoid any memory leaks or useless memory requirement

  • for of loop

  for (const month of kaalendar) {
      // do some stuff...
  }
