Laravel Livewire component to show Events in a good looking monthly calendar

Livewire Calendar

This package allows you to build a Livewire monthly calendar grid to show events for each day. Events can be loaded from within the component and will be presented on each day depending on the date of the event.

Preview

Installation

You can install the package via composer:

composer require asantibanez/livewire-calendar

Requirements

This package uses livewire/livewire (https://laravel-livewire.com/) under the hood.

It also uses TailwindCSS (https://tailwindcss.com/) for base styling.

Please make sure you include both of this dependencies before using this component.

Usage

In order to use this component, you must create a new Livewire component that extends from LivewireCalendar

You can use make:livewire to create a new component. For example.

php artisan make:livewire AppointmentsCalendar

In the AppointmentsCalendar class, instead of extending from the base Component Livewire class, extend from LivewireCalendar. Also, remove the render method. You'll have a class similar to this snippet.

class AppointmentsCalendar extends LivewireCalendar
{
    //
}

In this class, you must override the following method

public function events() : Collection
{
    // must return a Laravel collection
}

In the events() method, return a collection holding the events that will be displayed on the calendar. Events must be keyed arrays holding at least the following keys: id, title, description, date (date must be a Carbon\Carbon instance).

Example

public function events() : Collection
{
    return collect([
        [
            'id' => 1,
            'title' => 'Breakfast',
            'description' => 'Pancakes! 🥞',
            'date' => Carbon::today(),
        ],
        [
            'id' => 2,
            'title' => 'Meeting with Pamela',
            'description' => 'Work stuff',
            'date' => Carbon::tomorrow(),
        ],
    ]);
}

The date value will be used to determine to what day the event belongs to. To load values in the events() method, you can use the following component properties to filter your events.

• startsAt: starting date of month
• endsAt: ending date of month
• gridStartsAt: starting date of calendar grid. Can be a date from the previous month.
• endingStartsAt: ending date of calendar grid. Can be a date from the next month.

Example

public function events(): Collection
{
    return Model::query()
        ->whereDate('scheduled_at', '>=', $this->gridStartsAt)
        ->whereDate('scheduled_at', '<=', $this->gridEndsAt)
        ->get()
        ->map(function (Model $model) {
            return [
                'id' => $model->id,
                'title' => $model->title,
                'description' => $model->notes,
                'date' => $model->scheduled_at,
            ];
        });
}

Now, we can include our component in any view.

Example

<livewire:appointments-calendar/>

This will render a calendar grid.

By default, the component will render the current month. If you want to change the starting month, you can set the year and month props.

Example

<livewire:appointments-calendar
   year="2019"
   month="12"
/>

You should include scripts with @livewireCalendarScripts to enable drag and drop which is turned on by default. You must include them after @livewireScripts

@livewireScripts
@livewireCalendarScripts

The component has 3 public methods that can help navigate forward and backward through months:

• goToPreviousMonth
• goToNextMonth
• goToCurrentMonth

You can use these methods on extra views using before-calendar-view or after-calendar-view explained below.

Advanced usage

Ui customization

You can customize the behavior of the component with the following properties when rendering on a view:

• week-starts-at which can be a number from 0 to 6 according to Carbon days of week to indicate with which day of week the calendar should render first.

• event-view which can be any blade.php view that will be used to render the event card. This view will be injected with a $event variable holding its data.

• before-calendar-view and after-calendar-view can be any blade.php views that can be rendered before or after the calendar itself. These can be used to add extra features to your component using Livewire.

• drag-and-drop-classes can be any css class used to render the hover effect when dragging an event over each day in the calendar. By default, this value is border border-blue-400 border-4

• day-of-week-view which can be any blade.php view that will be used to render the header of each calendar day. This view will be injected the day property which is a Carbon instance of the day of the week.

<livewire:appointments-grid
    week-starts-at="0, 1, 2, 3, 4, 5 or 6. 0 stands for Sunday"
    event-view="path/to/view/starting/from/views/folder"
    day-of-week-view="path/to/view/starting/from/views/folder"
    before-calendar-view="path/to/view/starting/from/views/folder"
    after-calendar-view="path/to/view/starting/from/views/folder"
    drag-and-drop-classes="css classes"
/>

Advanced ui customization

(This options should be used using blade views based on the component default views)

To use these options, it is recommended to publish the base blade views used by the component and extend their behavior and styling to your liking. To do this, run php artisan vendor:publish and export the livewire-calendar tag.

• calendar-view which can be any blade.php view that renders the whole component. It's advised to override this view with an altered copy of the base calendar-view eg adding a view next to the component.

• day-view which can be any blade.php view that will be used to render each day of the month. This view will be injected with the following properties: componentId (id of the Livewire component) , day (day of the month as a Carbon instance) , dayInMonth (if the day is part of the month or not) , isToday (if the day is today's date) , events (events collection that correspond to this day)

Example

<livewire:appointments-grid
    calendar-view="path/to/view/starting/from/views/folder"
    day-view="path/to/view/starting/from/views/folder"
/>

Interaction customization

You can override the following methods to add interactivity to your component

public function onDayClick($year, $month, $day)
{
    // This event is triggered when a day is clicked
    // You will be given the $year, $month and $day for that day
}

public function onEventClick($eventId)
{
    // This event is triggered when an event card is clicked
    // You will be given the event id that was clicked 
}

public function onEventDropped($eventId, $year, $month, $day)
{
    // This event will fire when an event is dragged and dropped into another calendar day
    // You will get the event id, year, month and day where it was dragged to
}

Automatic polling

You can also add automatic polling if needed using pollMillis parameters. You can combo with pollAction in order to call a specific action in your component at the desired polling interval.

Disabling interactions

By default click and drag/drop events are enabled. To disable them you can use the following parameters when rendering the component

<livewire:appointments-grid
    :day-click-enabled="false"
    :event-click-enabled="false"
    :drag-and-drop-enabled="false"
/>
