// 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 = {
  title: "My birthday party",
  description: "Be there!",
  start: "2019-12-29 18:00:00 +0100",
  duration: [3, "hour"],
};

office365(event); // https://outlook.office.com/owa/...
yahoo(event); // https://calendar.yahoo.com/?v=60&title=...

Options

Property	Description	Allowed values
title (required)	Event title	String
start (required)	Start time	JS Date / ISO 8601 string / Unix Timestamp
end	End time	JS Date / ISO 8601 string / Unix Timestamp
duration	Event duration	Array with value (Number) and unit (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.
• 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)

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.
