gem 'add_to_calendar'
And then execute:
$ bundle
Or install it yourself as:
$ gem install add_to_calendar
# create new instance, adding your event attributes
@cal = AddToCalendar::URLs.new(
start_datetime: Time.new(2020,12,12,13,30,00,0),
title: "Christmas party!",
timezone: 'Europe/London'
)

<a href="<%= @cal.yahoo_url %>">Add to Yahoo Calendar</a>
<!-- for ical_url, android_url, apple_url and outlook_url you can set the filename like so -->
<a download="calendar-event.ics" href="<%= @cal.ical_url %>">Download iCal</a>

See #16).Yahoo, but this is because Yahoo is deprecating IE 11 support and only offers a simplified interface which does not work with the add event URL.I couldn't find an approriate gem or javascript library that did exactly what I wanted. So I decided to scratch my own itch to solve a problem for a startup I'm working on: https://www.littlefutures.org
