ical.js

(Formerly node-ical)

A tolerant, minimal icalendar parser for javascript/node (http://tools.ietf.org/html/rfc5545)

Install - Node.js

ical.js is availble on npm:

npm install ical

API

ical.parseICS(str)

Parses a string with an ICS File

var data = ical.parseFile(filename)

Example 1 - Print list of upcoming node conferences (see example.js)

'use strict';

const ical = require('ical');
const months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];

const data = ical.parseICS('content from ical file');

for (let k in data) {
	if (data.hasOwnProperty(k)) {
		var ev = data[k];
		if (data[k].type == 'VEVENT') {
			console.log(`${ev.summary} is in ${ev.location} on the ${ev.start.getDate()} of ${months[ev.start.getMonth()]} at ${ev.start.toLocaleTimeString('en-GB')}`);

		}
	}
}

Recurrences and Exceptions

Calendar events with recurrence rules can be significantly more complicated to handle correctly. There are three parts to handling them:

1. rrule - the recurrence rule specifying the pattern of recurring dates and times for the event.
2. recurrences - an optional array of event data that can override specific occurrences of the event.
3. exdate - an optional array of dates that should be excluded from the recurrence pattern.

See example_rrule.js for an example of handling recurring calendar events.
