ical-generator | ical-generator is a small piece of code which generates ical calendar files | Calendar library

I am using the ical-generator library to publish an iCalendar feed. The calendar contains an all-day event, which is a prediction of something happening on a given day. As the prediction gets updated, I want to change the date of the event accordingly.

This is how the feed looks like for an example event on 21 Feb 2021:

I have a database with a bunch of dates and an online overview where you can view them, now I know I can copy a URL from my Google Agenda and import this in other calendar clients so I can view the events there.

I want to generate an Express endpoint where I fetch every event every time the endpoint is called and return it in a format that can be imported by other calendar clients. Now with packages like iCal-generator I could generate, read, and return the file whenever a user requests the URL. but it feels redudent to write a file to my storage to then read it, return it and delete it every time it's requested.

What is the most effiecent way to go about this?

Not getting RSVP buttons in the email. I'm using "ical-generator" NPM to generate ics file.
