Show vcard as qrcode

[skjnldsv]

We can easily convert a vcard as a qrcode for easy flash and save in smartphone.
What do you think @nextcloud/contacts, do you feel like this is a good idea?

Example:

BEGIN:VCARD
VERSION:4.0
FN:Test 1
UID:dec8b591-ac52-437a-a9d1-060e714eb252
CATEGORIES:Group 1
END:VCARD

rel: https://www.npmjs.com/package/qrcode

What’s the use-case here though? Nextcloud Contacts is all about syncing, so you already will have it in your phone?

Also, which phone contacts app has a QR code reader?

[skjnldsv]

@jancborchardt it was for quick share! :)
You just pop it up on your phone and add it to your contacts

[Matthias84]

Same here, this feature would be useful to share contacts with guests or strangers quickly and without creating accounts, ...

[creopard]

It's a great idea, but it might not be necessary, as there are already phone apps that do all that on the fly.
(e.g.: https://play.google.com/store/apps/details?id=com.teacapps.barcodescanner and many more)
On the one hand these apps can create/display a QR code by sharing a contact via the app and on the other hand it can also scan a QR code and create a new contact automatically.

(I guess on most smartphones you would require an app to read QR codes at all...)

[jancborchardt]

@skjnldsv I’d close this issue cause it’s more like a »we could do this thing« than »this is something we actually need«. Sharing contacts would be much simpler and more versatile by sharing a link.

[skjnldsv]

@jancborchardt There is a loooot of enhancement requests on the contacts app, and I can't get myself to close them ^^

@skjnldsv Does this feature depend on any function provided by the server? I've discovered this function after I installed one of your test versions (20190328), but it seems not to work yet on my server (NC v15.0.5)

[skjnldsv]

@j-ed no, works from the app directly :)

[j-ed]

@skjnldsv That's weird. If I select that function on a contact only a white dot is shown on my server (NC v15.0.5 + FF v66.0.2):

[skjnldsv]

@j-ed that's interesting :)
Any log in the browser console?

[j-ed]

If I select a contact the following messages are logged:

XHR - PROPFIND - https://<my-nextcloud-server>/remote.php/dav/addressbooks/users/<user>/Kontakte/1b3105f6-cdef-42e2-abc5-c752a4cc908b.vcf

If I select the Generate QR code function the following messages are logged:

@j-ed those messages are not complete.
I would need the more detailed ones, you should have the ability to expand those errors, right?

I can also just create a debug release for you to try.

@skjnldsv I've installed the app, updated the server configuration, cleared the browser cache and started testing the function again. Unfortunately it shows less information than before but the result is the same. To sum up my tests with different browsers:

• Firefox 66.0.2 - only a dot is shown 😞
• Microsoft Edge - a QR code is displayed. 👍
• Vivaldi - a QR code is displayed. 👍

[skjnldsv]

Unfortunately it shows less information than before

what do you mean by that? 🤔

[j-ed]

@skjnldsv With the release you provided I couldn't see reference errors anymore. Only the following messages are shown:

[skjnldsv]

@j-ed thx! I fixed in on master!
It will be part of this week's release (3.1.0)

[j-ed]

@skjnldsv congrats! You're awesome 🥇
