`ical-generator` is a small but fine library with which you can very easily create a valid iCal calendars, for example
to generate subscriptionable calendar feeds.



## 📦 Installation

	npm install ical-generator


## ⚡️ Quick Start

```javascript
import ical, {ICalCalendarMethod} from 'ical-generator';
import http from 'node:http';

const calendar = ical({name: 'my first iCal'});

// A method is required for outlook to display event as an invitation
calendar.method(ICalCalendarMethod.REQUEST);

const startTime = new Date();
const endTime = new Date();
endTime.setHours(startTime.getHours()+1);
calendar.createEvent({
    start: startTime,
    end: endTime,
    summary: 'Example Event',
    description: 'It works ;)',
    location: 'my room',
    url: 'http://sebbo.net/'
});

http.createServer((req, res) => {
    res.writeHead(200, {
        'Content-Type': 'text/calendar; charset=utf-8',
        'Content-Disposition': 'attachment; filename="calendar.ics"'
    });

    res.end(calendar.toString());
}).listen(3000, '127.0.0.1', () => {
    console.log('Server running at http://127.0.0.1:3000/');
});
```

## 🕒 Date, Time & Timezones

ical-generator supports [native Date](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date),
[Day.js](https://day.js.org/en/), [Luxon's](https://moment.github.io/luxon/) [DateTime](https://moment.github.io/luxon/docs/class/src/datetime.js~DateTime.html)
and the older [moment.js](https://momentjs.com/) and [moment-timezone](https://momentjs.com/timezone/)
objects. You can also pass a string which is then passed to javascript's `Date` internally.

It is recommended to use UTC time as far as possible. `ical-generator` will output all time information as UTC time as
long as no time zone is defined. For day.js, a plugin is necessary for this, which is a prerequisite. If a time zone is
set, `ical-generator` assumes that the given time matches the time zone. If a time zone is used, it is also recommended
to use a VTimezone generator. Such a function generates a VTimezone entry and returns it. For example, ical-timezones can
be used for this:

```typescript
import {ICalCalendar} from 'ical-generator';
import {getVtimezoneComponent} from '@touch4it/ical-timezones';

const cal = new ICalCalendar();
cal.timezone({
    name: 'FOO',
    generator: getVtimezoneComponent
});
cal.createEvent({
    start: new Date(),
    timezone: 'Europe/London'
});
```

If a `moment-timezone` object or Luxon's `setZone` method works, `ical-generator` sets it according to the time zone set
in the calendar/event.

## 🙋 FAQ

### Where's the changelog?
It's [here](https://github.com/sebbo2002/ical-generator/blob/develop/CHANGELOG.md). If you need the changelog for
`ical-generator` 1.x.x and older, you'll find it [here](https://github.com/sebbo2002/ical-generator/blob/25338b8bf98f9afd3c88849e735fa33fa45fb766/CHANGELOG.md).

### I get a `ReferenceError: TextEncoder is not defined` error (in some browsers)
This library uses [`TextEncoder`](https://developer.mozilla.org/en-US/docs/Web/API/TextEncoder), which
is available in node.js ≥ 11.0.0 and [all modern browsers](https://caniuse.com/?search=textencoder).
Outdated browsers may not have the necessary API and generate this error when generating the calendar.
