Integrate CalDAV Protocol for appointment syncing

[viegelinsch]

Hi,

I would like to become independent from Google or any other cloud service. I host my own CalDAV server so it ould be consequent to subscribe to Easy!Appointments as additional CalDAV ressource.

Use case

Similar to the existing Google sync a configurable sync with a CalDAV calendar.
I would suggest parameters like:

const CALDAV_SYNC_FEATURE   = FALSE; // Enter TRUE or FALSE
const CALDAV_URL      = '';
const CALDAV_LOGIN_NAME   = '';
const CALDAV_PASSWORD  = '';

The CalDav ressource can be an iCloud account, a [own,next]cloud calendar or a Google calendar.

Or

If syncing is to complex to implement, maybe it is easier to integrate sabre/dav to offer the calendars with the bookings via CalDav. It would be one more calendar ressource to subscribe to, but this shouldn't be a problem.

Sponsoring (e.g. via Bountysource or FreedomSponsors) is an option.

With best regards,
Hendrik Eggers

Hello Hendrik,

thanks for posting! The CalDAV protocol seems to be very interesting. I will definitely check this out for a future release.

I'm currently preparing v1.2 for Beta release so it's a bit too late for this release but it may be integrated for v1.3.

In any case I am accepting donation through PayPal: paypal.me/alextselegidis

Seconded

Ohh, this feature would be great for me! At this moment i have to pay monthly for the CalDAV Feature to sync with my Smartphone and Thunderbird / Lightning. I want to be independent from Google Cal. I would donate for this feature! Is something planned about this? Actually i'm using this expensive service: https://de.doctena.de/ :-/

Hope to hear from you

Best Mark

Unfortunately this feature will not make it for v1.3, I'm actually almost done with the coding of the new release and will proceed to a beta release in the following days.

Stay tuned for further updates :)

@alextselegidis any news on the CalDAV support?

If not, I would like to start programming on this, in order to support at least a subset of the caldav standard.

But in case anyone already started, I want to avoid the issue.

What is the best way to extend on this code?

We need some sort of REST API specification so
server/dav/username/calendar or something like that and than the classes to deal with the conversion of the data in the database to CalDAV.

We can start with a read-only CalDAV so people can at least see the calendars from easyappointments.

@alextselegidis and @barrydegraaff I am also very excited about this feature and in my opinion this is a must have as we are working around Google & Co. with our own infrastructure such as nextcloud for calendars for example. Actually we are using a proprietary booking app that doesn't support CalDAV as well so we have to sync manually...
Is this planned in the closer future?
Can we support you to help implementing this? The issue starter has already suggested two options for donations.

Since this issue has been here for 2 years, probably no one at easyappointments want do implement it. We at https://zetalliance.org/ will be doing a crowdfunder in January to add easyappointments or something like that to Zimbra. But it is too early to tell if that is going to add WebDAV to this project.

Hello @barrydegraaff, @mokkin thank you for your interest, I find this a great feature too and also think that will make the integration with other systems so much easier. Unfortunately other tasks are being prioritized for the v1.4 so that the overall performance and user experience is enhanced. I cannot promise an integration soon. Any help is always appreciated though, stay tuned for updates :)

I'd like to see this as well. I administer both Nextcloud and Zimbra. I would love to see this feature. Thanks for your work!

CalDAV would make this unstoppable!

We need this too. Currently using Harmonizely.

I will donate up to $50 to the project when this is implemented. The sooner it's done the more money I'll donate. Right now I have to manually add events to both my main calendar (synced between all my devices with Nextcloud) and E!A, which is not an acceptable long-term solution.

I'll even accept a script that runs via cron to sync the calendars with each other. If I end up taking a couple hours and writing some code for this, I'm keeping the $50.

IMO this should be top priority (right under security bugs). This whole project is essentially a public UI for adding events to a calendar, so it's not helpful unless it can actually add events to a calendar!
