Examples

const config: CalendarOptions = {
  title: 'Happy Hour',
  location: 'The Bar, New York, NY',
  description: 'Let\'s blow off some steam with a tall cold one!',
  start: new Date('2022-07-08T19:00:00'),
  end: new Date('2022-07-08T23:30:00'),
  // an event that recurs every two weeks:
  recurrence: {
    frequency: 'WEEKLY',
    interval: 2
  }
}

const icalendar = new ICalendar(config)

iCalendar

With a reminder

icalendar
  .addAlarm({
    description: 'Remember this event'
    trigger: {
      minutes: 10
    }
  })

This will add a reminder that shows 10 minutes before the event.

With multiple events

const secondEvent = new ICalendar({
  title: 'Monthly Meeting with Boss Man',
  location: 'Conference Room 2A, Big Company, Brooklyn, NY',
  description: 'Meeting to discuss weekly things',
  start: new Date('2022-07-08T19:00:00'),
  recurrence: {
    frequency: 'MONTHLY'
  }
})

icalendar.addEvent(secondEvent)

This will add a second event to the same .ics file.

Adding other ICS properties

icalendar.addProperty('CATEGORIES', 'MEETINGS,MANAGEMENT')

This will add the CATEGORIES ICS property to the iCalendar instance.

Downloading

icalendar.download()

This will download Happy Hour.ics onto the user's device. On most mobile devices, this will open the default calendar app with the event.

Google Calendar

const googleCalendar = new GoogleCalendar(config)

googleCalendar.render()

googleCalendar.render() will return a URL that the user can navigate to and pre-fill event details:

https://calendar.google.com/calendar/render?action=TEMPLATE&text=Happy%20Hour&details=Let's%20blow%20off%20some%20steam%20with%20a%20tall%20cold%20one!&location=The%20Bar%2C%20New%20York%2C%20NY&dates=20220708T190000%2F20220708T230000&recur=RRULE%3AFREQ%3DWEEKLY%3BINTERVAL%3D1
