JavaScript library to generate an event link for Google Calendar, Yahoo! Calendar, Microsoft Outlook, etc.

Usage

// Usage with Node.js
const { google, outlook, office365, yahoo, ics } = require("calendar-link");

// Usage with TypeScript or ES6
import { google, outlook, office365, yahoo, ics } from "calendar-link";

// Set event as an object
const event = {
  uid: "your-unqiue-id",
  title: "My birthday party",
  description: "Be there!",
  start: "2019-12-29 18:00:00 +0100",
  duration: [3, "hour"],
};

// Then fetch the link
google(event); // https://calendar.google.com/calendar/render...
outlook(event); // https://outlook.live.com/owa/...
office365(event); // https://outlook.office.com/owa/...
yahoo(event); // https://calendar.yahoo.com/?v=60&title=...
ics(event); // standard ICS file based on https://icalendar.org

Options

NOTE: Only supported by google and ics | | description | Information about the event | String | | location | Event location in words | String | | busy | Mark on calendar as busy? | Boolean | | guests | Emails of other guests. This is currently only supported for google, outlook, outlookMobile, office365, office365Mobile and msTeams | Array of emails (String) | | url | Calendar document URL | String | | uid | Unique identifier for the event | String |

Notes

• Any one of the fields end, duration, or allDay is required.
• The allowed units in duration are listed here: https://day.js.org/docs/en/durations/creating#list-of-all-available-units.
• The url field defaults to document.URL if a global document object exists. For server-side rendering, you should supply the url manually.
• Not all calendars support the guests and url fields. For guests support in outlook/office calendar, this has been tested with outlook and office365 when this PR was implemented but we weren't able to test this with outlookMobile and office365Mobile so it might not work as expected. However, all outlook/office calendar links have same path and query string structure so we just added them as even if the query string is invalid, it will just be ignored and won't break anything.
• If you don't pass the start and end time in UTC, Google will convert it to UTC but Outlook won't, so it's a good idea to use UTC when passing dates and times
• There are some known issues in Office 365 because of which we can't generate a consistent link in all devices (#542)
• The uid field is currently optional and will generate a random ID if not provided. In a future version, this field will be required to ensure proper event identification and deduplication.

Compatibility

This package uses URLSearchParams (Node.js >= 10, 97%+ browsers), but if you need to include a polyfill, you can include url-search-params-polyfill first.
