documentation: how to run about cdav-library

[georgehrke]

do you have any documentation how to run or how to integrate with already existing node application?

As far as i can tell this library does not run on pure node.js. I tried to write our Tests in jest first, but I ended up using karma, because we require certain browser APIs like DomParser and XMLSerializer, latter one having no decent polyfill on NPM.

then open the web browser on localhost:3000 and will see some client but nothing happens.

It seems like you are looking for some GUI? This is simply a library to access Nextcloud's CalDAV/CardDAV server, used by the Contacts app (and future versions of the Calendar / Tasks app).

Please take note that this library is meant to communicate with Nextcloud's CalDAV/CardDAV server. While it's simply CalDAV/CardDAV and should in theory work with other servers, we didn't test this against any other server than Nextcloud and don't accept issues for other servers. Pull-requests that fix compatibility with other servers are certainly welcome though :)

Edit: To answer your main question about docs: You can run npm run build-doc to automatically generate documentation (as in API-reference) from source-code.

Hi George,
thanks fr answer, to be honest I seeking some first step for communication with nextcloud calendar via CalDAV. Just read/write/update the events for particular user.
I will go through yours test cases if there some for work with calendar.
any hint are welcomed
Best regards
Jan

Ah, in that case:

1. First you need to create the DavClient object.
   If you are running as a nextcloud app, you gotta hand over the requestToken

function xhrProvider() {
	var headers = {
		'X-Requested-With': 'XMLHttpRequest',
		'requesttoken': OC.requestToken
	}
	var xhr = new XMLHttpRequest()
	var oldOpen = xhr.open

	// override open() method to add headers
	xhr.open = function() {
		var result = oldOpen.apply(this, arguments)
		for (let name in headers) {
			xhr.setRequestHeader(name, headers[name])
		}
		return result
	}
	OC.registerXHRForErrorProcessing(xhr)
	return xhr
}

new DavClient({
	rootUrl: OC.linkToRemote('dav')
}, xhrProvider)

If you don't run inside Nextcloud, you gotta do the authentication yourself.

2. Start the client

await client.connect({enableCalDAV: true});
const calendars = await client.calendarHomes[0].findAllCalDAVCollections()
const events = await calendars[0].findAllVObjects()
console.log(events[0].data);
