Implement link previews

[juliusknorr]

• Requires Backend for reference metadata fetching server#33494
• Requires Implement reference preview rendering nextcloud-libraries/vue-richtext#743
• Decide if the link metadata should be fetched upfront when fetching the message list maybe => Moved to Should we fetch link preview data when returning messages already #7833
• Figure out a proper way to set the width => Moved to Fix link preview width when chat is in the sidebar #7832

For me links are not clickable anymore?

From the design review with @jancborchardt but might be a follow up:

• Talk could show this preview already when you paste a link in the composer, above your text, much like e.g. Signal does (similar style as for replying to others) Moved to Show link preview above the chat input when composing a message #7831

Talk could show this preview already when you paste a link in the composer, above your text, much like e.g. Signal does (similar style as for replying to others)

Definetly something for later. as we should first move to the RichContenteditable before duck typing a bigger hole within this already too overbloated component.

Moved the other open questions also to new issues so they can be done as a follow up

Will bump the lib to 2.0.0 and fix eslint

@nickvergessen Quick update, I did a follow up for the frontend bits and missed that i included the event in there. nextcloud/server#33755 adds that and I prepared a commit to either merge afterwards or cherry pick to this PR: f627c84

[nickvergessen]

But that is only for the "special" handling of files/talk/... not for general link previews, right?

[juliusknorr]

Yes, we can also add the event in a follow up.

Created #7837

Does anyone know how to enable this? This was marked as completed but for me link previews still show like this.

instead of this:

This issue for this feature was here:
nextcloud/server#32979

And was marked as a duplicate of this.
