Quick Guide

Import the module:

import * as ICS from 'ics-js';

Or import just what is needed:

import { VCALENDAR, VEVENT } from 'ics-js';

Create a component

const cal = new ICS.VCALENDAR();

The following components are implenented:

• VCALENDAR
• VEVENT
• VALARM
• VTODO

Add properties to a component

/**
 * Component#addProp(name, value, props = {}, skipTransformer = false)
 *
 * @param {string} name - Name of the property (e.g. DTSTAMP).
 * @param {*} [value] - Value of the property.
 * @param {Object} [props={}] - Object of properties for the property. Object keys and values are directly injected.
 * @param {boolean} [skipTransformer=false] - Explicitly determine if the property's value is transformed.
 */

cal.addProp('VERSION', 2) // Number(2) is converted to '2.0'
cal.addProp('PRODID', 'XYZ Corp');

Each component contains a list of property validations. Only valid properties can be added according to the RFC 5545 spec.

The following properties are implemented:

All other properties (e.g. SUMMARY, LOCATION) are stored as-is without transformations.

Nest a component

const event = new ICS.VEVENT();
event.addProp('UID');
event.addProp('DTSTAMP', new Date('2015-07-18 10:00:00'), { VALUE: 'DATE-TIME' });
event.addProp('ATTENDEE', null, {
  CN: 'Sample Company',
  RSVP: 'FALSE:mailto:foo@example.com'
})

cal.addComponent(event);

Each component contains a list of valid nested components. Only valid components can be nested according to the RFC 5545 spec.

Generate ICS data

cal.toString(); // Returns a string
cal.toBlob(); // Returns a Blob (or throws IncompatiblePlatform if Blob is undefined)
cal.toBase64(); // Returns a base64 encoded string
