The lightest Javascript calendar out there, without any dependency (no jQuery). This is a work in progress, but it is ready to be used in production.
The development files are using es2016, so I used babel with the es2015 preset and babily to minify the whole thing. Distribution files can be found under ./dist/. There are both normal and minified files.
If other kind developers want to lend a hand, I will obviously stop pushing directly to master and switch to a dev branch ;)
EDIT : This now has a dev branch. Thanks to @jamacon36, I will probably be maintaining this library again.

Hooks can be used to customize certain events and alter the way data is fetched, processed and rendered.
// Hooks on a specific instance
var calendarInstance = new JSCalendar(elem);
calendarInstance.on('eventName', (calendar, extra) => {
// calendar is the current calendar instance
// extra contains various data depending on the event
});
// Hooks on all instances
JSCalendar.on('eventName', (calendar, extra) => {
// Arguments are the same as above
});| Hook name | Context |
|---|---|
| new | Fired when a JSCalendar object is built using the default constructor. |
| init | Fired when the initialization logic is being processed for a newly built object. Fired before the DOM structure is created. |
| willPush | Fired before adding an item to the calendar dynamically. |
| pushed | Fired after adding an item to the calendar dynamically. |
| didNotPush | Fired after failing to add an item to the calendar dynamically. |
| willRender | Fired before rendering the calendar, also before fetching data from the data source if specified. |
| rendered | Fired after the render logic was processed. |
| dragging | Fired when an event is grabbed and ready to be moved around. |
| dropped | Fired when an event is dropped, the event cellMightMove will be triggered right after this one. |
| cellMightMove | Fired when a cell movement is validated. |
| cellMoved | Fired after an event was moved from a cell to another. |
| cellDidNotMoved | Fired when a cell could have moved, but the validation failed or the event was dropped onto its original cell. |
| matrixWillSet | Fired when a matrix is sent to replace the current one in the calendar's state. |
| matrixSet | Fired after a matrix was set as the current matrix state. |
| matrixWillAppend | Fired when another matrix is about to be inserted into the current matrix state |
| matrixAppended | Fired after another matrix was inserted into the current matrix state |
| willFetch | Fired before sending a fetch request to a data source. |
| fetched | Fired after receiving data from the data source. |
| viewWillChange | Fired before rendering a new view (month, week, day). |
| viewChanged | Fired after changing view. This will not fire if the view was set to the current one (wasn't changed). |
Those can be called using the class directly
// Will instanciate all calendars found under a certain wrapper
JSCalendar.find(document.getElementById("calendar-area"));
// Will return an instance of a calendar automatically generated using JSCalendar.find()
JSCalendar.getInstance(instanceid);
// Fires an event to all calendars from a specified instance
JSCalendar.fire(event, instance, extra);
/*
Returns an object :
{
numberOfDays : number, // Total number of days in the month
firstDay : number // Week day of the 1st of the month
}
*/
JSCalendar.getDaysInMonth(year, month);Associated with all JSCalendar instanciated objects. Chainable functions return "this" so you can chain multiple functions on one line.
// Must be called after instanciating [chainable]
calendar.init(callback)
// Previous, today, next [chainable]
// Those are called when pressing the direction buttons on the top bar.
// The calendar will be rendered at the end
calendar.goBack();
calendar.goNow();
calendar.goNext();
// Adding an item to the matrix [chainable]
/*
The first parameter is an object :
{
at : Date,
event : JSCalendarEventTemplate {
at : Date,
displayname : string,
duration : number,
color : string
}
}
*/
calendar.push(event);
// Destroy calendar reference [chainable]
calendar.destroy();
// Switch from current view to another [chainable]
/*
First parameter is on of the following strings :
month
week
day
*/
calendar.setView(view);
// Refresh and rebuild current view [chainable]
calendar.render();
// Merge a new matrix into the current state matrix [chainable]
/*
A matrix is an object formatted like the following :
matrix[year][month][day] = [JSCalendarEventTemplate];
The second parameter is a flag (true|false). If true,
the calendar will render after setting the new matrix
*/
calendar.appendMatrix(matrix, rerender);
// Set the current state matrix, and destroy the old one if any [chainable]
calendar.setMatrix(matrix, rerender);
// If a data source is specified, fetch a new matrix to append [chainable]
/*
This will request to the data source specified with query parameters
like the following :
year = current state year
month = current state month
day = current state day
Once finished, the provided callback will be executed
The second parameter is a flag (true|false), if set to true, will
fetch even is a cached version of the matrix exists.
*/
calendar.fetch(callback, force);
