Usage

Options

Usage

Svelte component / ES6 module

The first step is to install the Event Calendar core package:

npm install --save-dev @event-calendar/core

Then install any additional plugins you plan to use:

npm install --save-dev @event-calendar/time-grid

You must use at least one plugin that provides a view. The following plugins are currently available:

@event-calendar/day-grid
@event-calendar/list
@event-calendar/resource-time-grid
@event-calendar/time-grid
@event-calendar/interaction (doesn't provide a view)

Then, in your Svelte component, use the calendar something like this:

<script>
    import Calendar from '@event-calendar/core';
    import TimeGrid from '@event-calendar/time-grid';

    let plugins = [TimeGrid];
    let options = {
        view: 'timeGridWeek',
        events: [
            // your list of events
        ]
    };
</script>

<Calendar {plugins} {options} />

Or in ES6 module:

import Calendar from '@event-calendar/core';
import TimeGrid from '@event-calendar/time-grid';

let ec = new Calendar({
    target: document.getElementById('ec'),
    props: {
        plugins: [TimeGrid],
        options: {
            view: 'timeGridWeek',
            events: [
                // your list of events
            ]
        }
    }
});

The CSS is located at @event-calendar/core/index.css. If your build tool supports CSS processing, you can import it like this:

import '@event-calendar/core/index.css';

Pre-built browser ready bundle

Include the following lines of code in the <head> section of your page:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@event-calendar/build/event-calendar.min.css">
<script src="https://cdn.jsdelivr.net/npm/@event-calendar/build/event-calendar.min.js"></script>

Then initialize the calendar with something like this:

let ec = new EventCalendar(document.getElementById('ec'), {
    view: 'timeGridWeek',
    events: [
        // your list of events
    ]
});

Modifying options after initialization

You can modify the calendar options after initialization using the setOption method.

ec.setOption('slotDuration', '01:00');

In Svelte, you can simply update the original options object.

<script>
    import Calendar from '@event-calendar/core';
    import TimeGrid from '@event-calendar/time-grid';

    let plugins = [TimeGrid];
    let options = {
        view: 'timeGridWeek'
    };

    function updateOptions() {
        options.slotDuration = '01:00';
    }
</script>

<button on:click={updateOptions}>Change slot duration</button>
<Calendar {plugins} {options} />

Methods

Methods allow you to manipulate the Event Calendar after initialization. They are accessible from the calendar instance.

In Svelte, methods are available from a component instance:

<script>
    import Calendar from '@event-calendar/core';
    import TimeGrid from '@event-calendar/time-grid';

    let ec;
    let plugins = [TimeGrid];
    let options = {
        view: 'timeGridWeek',

Event object

This is a JavaScript object that the Event Calendar uses to store information about a calendar event.

Here are all properties that exist in Event object:

`id`	A unique string identifier of the event
`resourceIds`	An array of resource IDs that the event is associated with
`allDay`	`true` or `false`. Determines if the event is shown in the `all-day` slot
`start`	JavaScript Date object holding the event’s start time
`end`	JavaScript Date object holding the event’s end time
`title`	The text appearing on the event
`titleHTML`	The HTML version of the title
`editable`	`true`, `false` or `undefined`. The value overriding the editable setting for this specific event
`startEditable`	`true`, `false` or `undefined`. The value overriding the eventStartEditable setting for this specific event
`durationEditable`	`true`, `false` or `undefined`. The value overriding the eventDurationEditable setting for this specific event
`display`	The rendering type of the event. Can be `'auto'` or `'background'` In addition, in your callback functions, you may get the `'ghost'`, `'preview'` and `'pointer'` for this property, which are internal values and are used, for example, to display events during drag-and-drop operations
`backgroundColor`	The eventBackgroundColor override for this specific event
`extendedProps`	A plain object holding miscellaneous properties specified during parsing in the explicitly given `extendedProps` field

Parsing event from a plain object

When Event Calendar receives an array of plain event’s objects either from the events option or as a result of an HTTP request to a URL of an event source, it parses the input objects into proper Event objects.

Here are all admissible fields for the event’s input object:

`id`	`string` or `integer` A unique identifier of the event. Default `auto-generated value`
`resourceId`	`string` or `integer` An ID of a resource that the event is associated with. This field is not used if `resourceIds` is provided. Default `undefined`
`resourceIds`	`Array` An array of resource IDs that the event is associated with. This field is used instead of `resourceId`. Default `[]`
`allDay`	`boolean` Determines if the event is shown in the all-day slot. Default `false`
`start`	`string` or `Date` This should be either an ISO8601 datetime string like `'2022-12-31 09:00:00'`, or a JavaScript Date object holding the event’s start time
`end`	`string` or `Date` This should be either an ISO8601 datetime string like `'2022-12-31 13:00:00'`, or a JavaScript Date object holding the event’s end time
`title`	`string` The text that will appear on the event. Default `''`
`titleHTML`	`string` The HTML version of the title to be displayed instead of the text version. Default `''`
`editable`	`boolean` Overrides the master editable option for this single event. Default `undefined`
`startEditable`	`boolean` Overrides the master eventStartEditable option for this single event. Default `undefined`
`display`	`string` The rendering type of the event. Can be `'auto'` or `'background'`. Default `'auto'`
`backgroundColor`	`string` Sets the event’s background color just like the calendar-wide eventBackgroundColor option. Default `undefined`
`color`	`string` This is currently an alias for the `backgroundColor` field. Default `undefined`
`extendedProps`	`object` A plain object with any miscellaneous properties. It will be directly transferred to the `extendedProps` property of the Event object. Default `{}`

Duration object

This is a JavaScript object that the Event Calendar uses to store information about a period of time, like 30 minutes or 1 day and 6 hours.

Here are all properties that exist in Duration object:

`years`	The number of years in duration
`months`	The number of months in duration
`days`	The number of days in duration
`seconds`	The number of seconds in duration. If you want hours and minutes, you need to do division on this property
`inWeeks`	Determines whether the duration represents a time period in weeks. This value is set during parsing the input data

Parsing duration from input values

When Event Calendar receives a value for options like duration, scrollTime, slotDuration and others, it parses it into a proper Duration object.

The admissible input value can be specified in one of three formats:

an object with any of the following keys: year, years, month, months, day, days, minute, minutes, second, seconds
a string in the format hh:mm:ss or hh:mm. For example, '05:00' specifies 5 hours
an integer specifying the total number of seconds

Resource object

This is a JavaScript object that the Event Calendar uses to store information about a resource. Calendar events can be associated with resources and displayed separately using the resource view.

Here are all properties that exist in Resource object:

`id`	The unique string identifier for the resource
`title`	The title of the resource
`titleHTML`	The HTML version of the title

Parsing resource from a plain object

When Event Calendar receives an array of plain resource’s objects for the resources option, it parses the input objects into proper Resource objects.

Here are all admissible fields for the resource’s input object:

`id`	`integer` or `string` Uniquely identifies the resource. Event objects with a corresponding `resourceIds` field will be linked to this resource. Will be coerced into a `string`
`title`	`string` Text that will be displayed on the resource when it is rendered. Default `''`
`titleHTML`	`string` The HTML version of the title to be displayed instead of the text version. Default `''`

View object

A View object contains information about a calendar view, such as title and date range.

Here are all properties that exist in View object:

`type`	Name of the view
`title`	Title text that is displayed at the top of the header toolbar
`currentStart`	JavaScript Date that is the start of the interval the view is trying to represent. For example, in month view, this will be the first day of the month. This value disregards hidden days
`currentEnd`	JavaScript Date that is the end of the interval the view is trying to represent. Note: This value is exclusive. For example, in month view, this will be the day after the last day of the month. This value disregards hidden days
`activeStart`	JavaScript Date that is the first visible day. In month view, this value is often before the 1st day of the month, because most months do not begin on the first day-of-week
`activeEnd`	JavaScript Date that is the last visible day. Note: This value is exclusive
