add event to existing ics file?

[tomaslundborg]

I want to offer this to clients. And, once they make a booking, the new event is added to the already existing ics file.

Can only see that one can generate new, but what about parsing existing and adding event to that, saving it again? And waiting for the outlook/google cal etc to poll new updates.

Or am I thinking about this in the wrong way? How do ppl usually do this?

First a general note: This package does not assume you're storing a regular .ics file somewhere. It is intended for serving a "calendar feed", which is an iCalendar file served via HTTP.

I'm going to assume you want to extend an existing calendar feed with another event (or set of events). Generating a separate new feed is not an option?

I am searching for a calendar feed that one can subscribe to, but that also pushes changes and additions to the subscribers too. As I understand, webcal:// is the (a?) protocol for this.

My municipal cleaner service publishes the garbage pick up dates a year in advance. But if there are any changes, I see those in my Google calendar. This is the uri for my street webcal://wasteprod2api.ximmio.com/api/CallIcal?cn=Avalex&x=f7a74ad1-fdbf-4a43-9f91-44644f4d4222&ty=&ua=571700cc4a1157156d2a50fbaff49fb62441c767&sd=2022-12-25&ed=2024-01-27&path=https://wasteprod2api.ximmio.com&ln=nl&nt=7

Is this possible by ics service? If not, would it be a big effort to add ?

Kind regards.

AFAIK pushing to users' devices is not possible with any of the calendar feed/subscription formats. All of them assume that the client (or some cloud service acting on behalf of the client) polls the calendar feed regularly.

The iCal/webcal: ecosystem is not very well-specified AFAICT. It's a lot of de-facto standards and some actual formal standards put together, with implementations slightly varying in how they work. Nevertheless, a basic calendar feed should work with all major calendar apps/services.

Yes, exactly this is ics-service's goal: You specify calendar events in the ics@3 format, ics-service serves a calendar feed containing them.
