Full-sized drag & drop event calendar with resource & timeline views
Full-sized drag & drop JavaScript event calendar with resource & timeline views:
Inspired by FullCalendar, implements similar options.
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-timeline@event-calendar/resource-time-grid@event-calendar/time-grid@event-calendar/interaction (doesn't provide a view)Then, in your JavaScript module:
import Calendar from '@event-calendar/core';
import TimeGrid from '@event-calendar/time-grid';
// Import CSS if your build tool supports it
import '@event-calendar/core/index.css';
let ec = new Calendar({
target: document.getElementById('ec'),
props: {
plugins: [TimeGrid],
options: {
view: 'timeGridWeek',
events: [
// your list of events
]
}
}
});
Or in your Svelte component, use the calendar 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} />
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@3.7.1/event-calendar.min.css">
<script src="https://cdn.jsdelivr.net/npm/@event-calendar/build@3.7.1/event-calendar.min.js"></script>
Please note that the file paths contain an indication of a specific version of the library. You can remove this indication, then the latest version will be loaded:
<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>But it is recommended to always specify the version and explicitly update it if necessary, in order to avoid unpredictable problems when a new version of the library is released.
Then initialize the calendar like this:
let ec = new EventCalendar(document.getElementById('ec'), {
view: 'timeGridWeek',
events: [
// your list of events
]
});
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} />

booleantrueDetermines when event fetching should occur.
When set to true (the default), the calendar will only fetch events when it absolutely needs to, minimizing HTTP requests. For example, say your calendar starts out in month view, in February. The Event Calendar will fetch events for the entire month of February and store them in its internal storage. Then, say the user switches to week view and begins browsing the weeks in February. The calendar will avoid fetching events because it already has this information stored.
When set to false, the calendar will fetch events any time the view is switched, or any time the current date changes (for example, as a result of the user clicking prev/next).

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',
eventSources: [{events: function() {
console.log('fetching...');
return [];
}}]
};
function invokeMethod() {
ec.refetchEvents();
}
</script>
<button on:click={invokeMethod}>Refetch events</button>
<Calendar bind:this={ec} {plugins} {options} />
name string The option namemixed or undefinedThis method allows you to get the current value of any calendar option.
// E.g. Get current date
let date = ec.getOption('date');
name string The option namevalue mixed The new option valueEventCalendar The calendar instance for chainingThis method allows you to set new value to any calendar option.
// E.g. Change the current date
ec.setOption('date', new Date());
event object A plain object that will be parsed into an Event objectnullAdds a new event to the calendar.
id string|integer The ID of the eventnullReturns a single event with the matching id.
Event[] Array of Event objectsReturns an array of events that the calendar has in memory.
id string|integer The ID of the eventEventCalendar The calendar instance for chainingRemoves a single event with the matching id.
event object A plain object or Event objectEventCalendar The calendar instance for chainingUpdates a single event with the matching event.id.
EventCalendar The calendar instance for chainingRefetches events from all sources.
object or nullReturns an info object with data as if the dateClick event had fired for that point.
info object contains the following properties:
|
| JavaScript Date object for the date and time |
|
|
|
|
| HTML element that represents the whole-day that contains the point |
|
|
If the current view is a resource view, the Resource object that owns this date |
Using this method, you can, for example, find out on which day a click occurred inside a multi-day event. To do this, inside eventClick, pass the jsEvent.clientX and jsEvent.clientY coordinates to dateFromPoint and get the desired date.
undefinedDestroys the calendar, removing all DOM elements, event handlers, and internal data.
Please note that this method is not available in Svelte. Instead, the calendar is destroyed gracefully when the component containing it is destroyed.
ViewReturns the View object for the current view.
EventCalendar The calendar instance for chainingMoves the current calendar date forward by 1 day/week/month (depending on the current view).
EventCalendar The calendar instance for chainingMoves the current calendar date backward by 1 day/week/month (depending on the current view).
EventCalendar The calendar instance for chainingClears the current selection. See selectable.
The content value can be presented in the following forms:
'some text'{html: '<p>some HTML</p>'}{domNodes: [node1, node2, ...]}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:
|
| A unique string identifier of the event |
|
| An array of resource IDs that the event is associated with |
|
|
|
|
| JavaScript Date object holding the event’s start time |
|
| JavaScript Date object holding the event’s end time |
|
|

A plain object holding miscellaneous properties specified during parsing in the explicitly given |
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:

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:
|
| The number of years in duration |
|
| The number of months in duration |
|
| The number of days in duration |
|
| The number of seconds in duration. If you want hours and minutes, you need to do division on this property |
|
| Determines whether the duration represents a time period in weeks. This value is set during parsing the input data |
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:
year, years, month, months, day, days, minute, minutes, second, secondshh:mm:ss or hh:mm. For example, '05:00' specifies 5 hoursThis 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:
|
| The unique string identifier for the resource |
|
|
The title of the resource. See Content |
|
| Default background color for this resource's events |
|

| Nested resources. See below |
The timeline views support displaying nested resources. Nested resources can be collapsed or expanded using an additional button that appears before the parent resource name. To pass nested resources, use the children field:
resources: [
{
id: 1,
title: 'Resource A',
children: [
{
id: 11,
title: 'Resource A1'
},
{
id: 12,
title: 'Resource A2'
}
]
}
]
A View object contains information about a calendar view, such as title and date range.
Here are all properties that exist in View object:
|
| Name of the view |
|
| Title text that is displayed at the top of the header toolbar |
|
| 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 |
|
| 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 |
|
| 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 |
|
| JavaScript Date that is the last visible day. Note: This value is exclusive |
The library provides a built-in dark theme. You can activate it by adding the ec-dark CSS class to any parent element of the calendar, e.g. <body class="ec-dark">.
If you want the dark theme to be activated automatically based on the preferred color scheme, then use the ec-auto-dark CSS class instead.
Please note that the dark theme does not change the background and font color in the calendar. These are assumed to be set by the page styles, and the calendar inherits these styles.
If you do need to set the background or font color of the calendar, use local CSS variables for this:
.ec {
--ec-bg-color: #22272e;
--ec-text-color: #adbac7;
}
A list of all available CSS variables can be found here.
The latest versions of Chrome, Firefox, Safari, and Edge are supported.
The library is compiled to support browsers that match the following browserslist configuration:
defaults and supports fetch. You can see the resulting list here.
