The initial goal was to use it as a replacement for libical in the Mozilla Calendar Project, but the library has been written with the web in mind. This library enables you to do all sorts of cool experiments with calendar data and the web. Most algorithms here were taken from libical. If you are bugfixing this library, please check if the fix can be upstreamed to libical.
If you want to try out ICAL.js right now, there is a jsfiddle set up and ready to use. Read on for documentation and example links.
ICAL.js has no dependencies and is written in modern JavaScript. You can install ICAL.js via npm, if you would like to use it in Node.js:
The stock ical.js does not register any timezones, due to the additional size it brings. If you'd like to do timezone conversion, and the timezone definitions are not included in the respective ics files, you'll need to use ical.timezones.js or its minified counterpart.
This file is not included in the distribution since it pulls in IANA timezones that might change regularly. See the github actions on building your own timezones during CI, or grab a recent build from main.
