Use viewer in other apps

[julien-nc]

Hey!

I'm currently developing Maps app and would like to be able to launch the Viewer for pictures. Currently I'm opening a new tab to the gallery app but it would be nice to stay in the Maps app. I might want to use Viewer in GpxPod too.

When I include Viewer (script('viewer', 'viewer');) I get this in the browser:

OCA.Viewer initialized                Viewer.js:37:10
TypeError: OCA.Files is undefined     Viewer.vue:369
TypeError: OCA.Files is undefined     Viewer.vue:369

Would it be possible to make Viewer (or part of it) independent from files app?

Yes, this is planned :)
I actually took some steps next week to start going this way ;)

The last steps are actually quite easy.
We should just check against OCA.Files and not register new actions handlers if it does not exists.
After that everything should works! (Though other apps that register their views will not be loaded as you also need their script, so viewer will be standalone with minimal default support: images + video)

Yay! Great. Looking forward to it. Thanks for the quick answer!

Great!.
However, I have a special request.. 😅

Can it become independent of OCA.Files?
My idea is to do something similar, but for the application of facerecognition. Provide something similar to "OCA.Files" where you generate a virtual list, and in these case allow to see all the photos where there is a particular person. The same can apply to browse photos by nextcloud tags, project, etc.

Here, nextcloud/maps#93 (comment)
You point out that it is enough if we go through directories for Maps, but what happens if in Android Client we have activated the option to upload images by date.? Half of the photos of some vacations can be in one directory, and half in the other. So, this also applies for maps

What do you think? 😄

p.s: Maybe the answer goes to extend OCA.Files, to generate the virtual views in the application of files too, but I think here is the starting point.
Note that if we go to the favorites view, when clicking a favorite image, this viewer is launched, but when moving to the right, continue with photos of the same directory, and we would expect to continue seeing the favorites... So this idea also applies.. 😅

That's the whole goal of this issue yes :)
Being able to launch the viewer regardless of any app you're currently in !

@skjnldsv is this ready now that #271 is merged?

[skjnldsv]

Yes :)
Please test it!

[szaimen]

@eneiluj Maybe you could test it in the Maps app? :)

[julien-nc]

Great, it works fine! I tried v18.0.0beta3.

nextcloud/maps#227 makes it happen in Maps app.

Thanks a lot.
