Could I get some reviews on this, please?

P.S. It seems that Jenkins is failing on the npm install step, maybe it's some caching issue.

@availchet Sure. Please let me know which Go and nodejs+npm versions you used for this?

If I can build it, I'll merge your PR and deploy it on a Mattermost deployment I have for a SMB IT I manage in order to test it at a larger scale :).

@wget These are the ones I am using:

$ node -v
v16.13.1

$ npm -v                             
8.1.2

$ go version
go version go1.20.1 darwin/amd64

I follow this discussion and can confirm that the test version is working like a charm with Mattermost 7.8.0:

• Saving files works (local storage)
• Permissions work
• Switch between read / edit mode works
• Creating new files DOESN'T work while the Fileblocker plugin is enabled: I can open the create dialog, enter the filename & chose the file type, but the document doesn't get created. I created an issue on the Fileblocker repo, as the error messages point to the Fileblocker plugin. Collabora plugin not working correctly when file blocker is enabled muratbayan/mattermost-file-blocker#26

Hello,
thank you so much for your work, we are finally able to use this mattermost integration on an up-to-date instance! :)
As far as I understand, with the current implementation it is not possible to use the integration in the desktop and mobile apps, because there is no context menu for files what so ever. Would it be possible to add support for those clients? Maybe through a link based approach, that automatically generates a link for a given file, which redirects you to the collabora web app in the browser?

Again, thank you for your hard work!
Greetings!

Hi @AdmerStroh
the collabora mattermost implementation is realized by a plugin. AFAIK plugins are not supported on the mobile app. The desktop application works fine for us with this version:

Creating a new file is realized thru the attachment symbol when writing a new message. Permissions are supported.

Any progress here? Looking forward to it!
