Day Picker - Alpine.js

[!WARNING]
This component is still work in progress, may not work properly in international contexts and present unsolved issues.

How to use this component

Import the component and register it using Alpine.data():

import Alpine from 'alpinejs';
import { DayPicker } from 'alpine-day-picker';

Alpine.data('DayPicker', DayPicker);

Alpine.start();

...and use it wherever you need it!

<div x-data="DayPicker($refs.dayInput)">
    <input type="date" x-model="value" x-ref="dayInput">
    
    <template x-for="day of daysOfTheWeek" :key="day.getTime()">
        <a href="#" role="button" x-on:click.prevent="value = day" x-bind:aria-disabled="!isDayAvailable(day)">
            <div>
                <span x-text="day.getDate()"></span>
                <span x-text="day.toLocaleString('en', { month: 'long' })"></span>
                <span x-text="day.getFullYear()"></span>
                <span x-text="day.toLocaleString('en', { weekday: 'long' })"></span>
            </div>
        </a>
    </template>
</div>

Choose your structure

The component lets you decide how to control and display the days of the week; right now it comes unstyled to freely adapt to every need.

So customize it as you prefer!

Adapts to your needs

DayPicker($refs.dayInput, {
    startingDayOfTheWeek: 1,
    excludedWeekdays: [ 0, ],
    holidays: [
        new Date(2024, 2, 8), // Add a fixed date
        '12-25', // Or flexible ones as strings...
        { month: 1, day: 1 }, // ...and objects!
    ],
})

Or you can use take advantage of some utility enums that may result useful:

// main.js
import Alpine from 'alpinejs';
import { DayPicker, Months, Weekdays } from 'alpine-day-picker';

Alpine.data('DayPicker', DayPicker);

window.Months = Months;
window.Weekdays = Weekdays;

Alpine.start();

// In your x-data
DayPicker($refs.dayInput, {
    startingDayOfTheWeek: Weekdays.MONDAY,
    excludedWeekdays: [ Weekdays.SUNDAY, ],
    holidays: [
        new Date(2024, 2, 8), // Add a fixed date
        '12-25', // Or flexible ones as strings...
        { month: Months.JANUARY, day: 1 }, // ...and objects!
    ],
})

How to ensure date is valid

When the date input has a min and/or a max, the component will let you limit the selection of these elements (if you desire) by considering them unavailable (like holidays or excluded weekdays).

[!CAUTION]
Right now, these fields are not dynamic, so you need to call the updateMinMax() method to refresh them.
