ical-generator is a small piece of code which generates ical calendar files. I use this to generate subscriptionable
calendar feeds.


## Installation

	npm install ical-generator


## Upgrade from 0.1.x

ical-generator 0.2.0 introduces a completely new API, but because you guys used 0.1.x a lot, the old API still works. So
you should be able to upgrade from ical-generator 0.1.x to 0.2.0 without any code changes. In case you need the old API
docs, you can find the deprecated documentation [here](https://github.com/sebbo2002/ical-generator/blob/0.1.10/README.md).

In case you have any issues with the new API, feel free to [create an issue](https://github.com/sebbo2002/ical-generator/issues/new).


## Quick Start

```javascript
var ical = require('ical-generator'),
	http = require('http'),
	cal = ical({domain: 'github.com', name: 'my first iCal'});

// overwrite domain
cal.domain('sebbo.net');

cal.createEvent({
	start: new Date(),
	end: new Date(new Date().getTime() + 3600000),
	summary: 'Example Event',
	description: 'It works ;)',
	location: 'my room',
	url: 'http://sebbo.net/'
});

http.createServer(function(req, res) {
	cal.serve(res);
}).listen(3000, '127.0.0.1', function() {
    console.log('Server running at http://127.0.0.1:3000/');
});
```


## Just another example

```javascript
var ical = require('ical-generator'),

    // Create new Calendar and set optional fields
    cal = ical({
        domain: 'sebbo.net',
        prodId: {company: 'superman-industries.com', product: 'ical-generator'},
        name: 'My Testfeed',
        timezone: 'Europe/Berlin'
    });

// You can also set values like this…
cal.domain('sebbo.net');

// … or get values
cal.domain(); // --> "sebbo.net"

// create a new event
var event = cal.createEvent({
    start: new Date(),
    end: new Date(new Date().getTime() + 3600000),
    timestamp: new Date(),
    summary: 'My Event',
    organizer: 'Sebastian Pekarek <mail@example.com>'
});

// like above, you can also set/change values like this…
event.summary('My Super Mega Awesome Event');

// get the iCal string
cal.toString(); // --> "BEGIN:VCALENDAR…"


// You can also create events directly with ical()
cal = ical({
    domain: 'sebbo.net',
    prodId: '//superman-industries.com//ical-generator//EN',
    events: [
        {
            start: new Date(),
            end: new Date(new Date().getTime() + 3600000),
            timestamp: new Date(),
            summary: 'My Event',
            organizer: 'Sebastian Pekarek <mail@example.com>'
        }
    ]
}).toString();
```



## API

### ical-generator

#### ical([_Object_ options])

Creates a new [Calendar](#calendar) ([`ICalCalendar`](#calendar)).

```javascript
var ical = require('ical-generator'),
    cal = ical();
```

You can pass options to setup your calendar or use setters to do this.

```javascript
var ical = require('ical-generator'),
    cal = ical({domain: 'sebbo.net'});

// is the same as

cal = ical().domain('sebbo.net');

// is the same as

cal = ical();
cal.domain('sebbo.net');
```


### Calendar

#### domain([_String_ domain])

Use this method to set your server's hostname. It will be used to generate the feed's UID. Default hostname is your
server's one (`require('os').hostname()`).


#### prodId([_String_|_Object_ prodId])

Use this method to overwrite the default Product Identifier (`//sebbo.net//ical-generator//EN`). `prodId` can be ether
a valid Product Identifier or an object:

```javascript
cal.prodId({
	company: 'My Company',
	product: 'My Product',
	language: 'EN' // optional, defaults to EN
});

// OR

cal.prodId('//My Company//My Product//EN');
```


#### name([_String_ name])

Use this method to set your feed's name. Is used to fill `NAME` and `X-WR-CALNAME` in your iCal file.


#### url([_String_ url])

Use this method to set your feed's URL.

```javascript
var cal = ical().url('https://example.com/calendar.ical');
```


#### timezone([_String_ timezone])

Use this method to set your feed's timezone. Is used to fill `TIMEZONE-ID` and `X-WR-TIMEZONE` in your iCal.

```javascript
var cal = ical().timezone('Europe/Berlin');
```

#### method([_String_ method])

Calendar method. May be any of the following: `publish`, `request`, `reply`, `add`, `cancel`, `refresh`, `counter`, `declinecounter`.


#### ttl([_Number_ ttl])

Use this method to set your feed's time to live. Is used to fill `REFRESH-INTERVAL` and `X-PUBLISHED-TTL` in your iCal.

```javascript
var cal = ical().ttl(60 * 60 * 24);
```


#### createEvent([_Object_ options])

Creates a new [Event](#event) ([`ICalEvent`](#event)) and returns it. Use options to prefill the event's attributes.
Calling this method without options will create an empty event.

```javascript
var ical = require('ical-generator'),
    cal = ical(),
    event = cal.createEvent({summary: 'My Event'});

// overwrite event summary
event.summary('Your Event');
```


#### events([_Object_ events])

Add Events to calendar or return all attached events.

```javascript
var cal = ical();
cal.events([
    {
        start: new Date(),
        end: new Date(new Date().getTime() + 3600000),
        summary: 'Example Event',
        description: 'It works ;)',
        url: 'http://sebbo.net/'
    }
]);

cal.events(); // --> [ICalEvent]
```


#### save(**_String_ file**[, _Function_ cb])

Save Calendar to disk asynchronously using [fs.writeFile](http://nodejs.org/api/fs.html#fs_fs_writefile_filename_data_options_callback).


#### saveSync(**_String_ file**)

Save Calendar to disk synchronously using [fs.writeFileSync](http://nodejs.org/api/fs.html#fs_fs_writefilesync_filename_data_options).


#### serve(**_http.ServerResponse_ response**)

Send Calendar to the User when using HTTP. See Quick Start above.


#### toString()

Return Calendar as a String.


#### toJSON()

Return a shallow copy of the calendar's options for JSON stringification. Can be used for persistance.
```javascript
var cal = ical(),
    json = JSON.stringify(cal);
    
// later
cal = ical(json);
```

#### length()

Returns the ammount of events in the calendar.


#### clear()

Empty the Calender.



### Event

#### uid([_String_|_Number_ uid]) or id([_String_|_Number_ id])

Use this method to set the event's ID. If not set, an UID will be generated randomly.  When output, the ID will be suffixed with '@' + your calendar's domain.


#### sequence([_Number_ sequence])

Use this method to set the event's revision sequence number of the
calendar component within a sequence of revisions.


#### start([_Date_ start])

Appointment date of beginning as Date object. This is required for all events!


#### end([_Date_ end])

Appointment date of end as Date object.


#### timezone([_String_ timezone])

Use this method to set your event's timezone using the TZID property parameter on start and end dates, as per [date-time form #3 in section 3.3.5 of RFC 554](https://tools.ietf.org/html/rfc5545#section-3.3.5).

This and the 'floating' flag (see below) are mutually exclusive, and setting a timezone will unset the 'floating' flag.  If neither 'timezone' nor 'floating' are set, the date will be output with in UTC format (see [date-time form #2 in section 3.3.5 of RFC 554](https://tools.ietf.org/html/rfc5545#section-3.3.5)).


#### timestamp([_Date_ stamp]) or stamp([_Date_ stamp])

Appointment date of creation as Date object. Default to `new Date()`.


#### allDay([_Boolean_ allDay])

When allDay == true -> appointment is for the whole day


#### floating([_Boolean_ floating])

Appointment is a "floating" time. From [section 3.3.12 of RFC 554](https://tools.ietf.org/html/rfc5545#section-3.3.12):

> Time values of this type are said to be "floating" and are not
> bound to any time zone in particular.  They are used to represent
> the same hour, minute, and second value regardless of which time
> zone is currently being observed.  For example, an event can be
> defined that indicates that an individual will be busy from 11:00
> AM to 1:00 PM every day, no matter which time zone the person is
> in.  In these cases, a local time can be specified.

This and the 'timezone' setting (see above) are mutually exclusive, and setting the floating flag will unset the 'timezone'.  If neither 'timezone' nor 'floating' are set, the date will be output with in UTC format (see [date-time form #2 in section 3.3.5 of RFC 554](https://tools.ietf.org/html/rfc5545#section-3.3.5)).

#### createAttendee([_Object_ options])

Creates a new [Attendee](#attendee) ([`ICalAttendee`](#attendee)) and returns it. Use options to prefill the attendee's attributes.
