Does nodebb support following/joining federated communities? And does it support switching to a threaded view?
-
@[email protected] Following groups on other sites works well. The current default theme doesn't do visual threading, but reply relationships are maintained and linked. QuickReply kind of quietly discourages direct replies to comments, though, so I imagine many users - especially those new to the bulletin board experience - may end up replying to OPs, especially without a threaded UI.
I'm sure there's nothing stopping someone from making a threaded theme, though.
-
@[email protected] there is some active discussion around how to better represent federated communities. The current iteration of NodeBB will bring them in as regular user accounts that can be followed, and this is tested and working with Lemmy and PieFed, primarily.
@Kichae, two things:
-
You're right, and I've brought that up internally. It's difficult to justify the change in UX, but there may be a way to support both UX flows with the addition of a checkbox that adjusts
toPid/inReplyTo. The downside of that is the whole point of the quick-reply box is to actively limit the number of visible controls
-
A threaded view is difficult because it is not scalable, at least with the way our current backend is built out. We load topics page by page, which means every page is loading in
O(x*n)time¹, wherexis the number of posts. If we wanted to load a threaded view, we'd have to query every single post and build the threaded relationship on-the-fly, since we don't maintain that in the backend, and that's...O(a lot more)²
There is a way we can approximate the threaded UI, but @baris and I haven't played around with it for a couple years...
¹ I am not well-versed in computer science so I may be wildly wrong about this
² very scientific, yes. -

@julian Personally, I find the reply list -- and especially the new auto-quote back-references a more than sufficient solution, but then I don't think threaded discussions are a value-add to the bulletin board experience.
It's just not part of the expected UX, and kind of breaks the BB UX, which has always been built on the expectation of reverse-chronological posting. Not that I don't understand the utility, or someone having the preference. Threading is now ubiquitous on other social modals. It's become part of the design language of Web 2.0.
Some platforms that use threading now only load the first couple of levels of replies. I wonder if that's something that's currently possible via theme work, or if a plugin would be required, or even if work on core would be necessary. Or if some sort of popup modal that loads threads might be viable? Solutions that wouldn't require the threads to be pre-loaded.
-
@Kichae the workaround that @baris and I played around with (very) briefly involved the "x replies" expando button.
I think there were some rather simple adjustments made to load only one level at a time, and that was essentially the "threaded" view.
I don't remember the details any more, perhaps he does.

Yeah there is a config property
config.showNestedReplieshttps://github.com/NodeBB/NodeBB/blob/master/public/src/client/topic/replies.js#L40, it is not exposed anywhere but a plugin can set this totrueinfilter:config.getand that would cause more than one level of replies to show up. However the posts all show up at the top level in chronological order, since core adds everything at the top level(tid:posts) and then adds it topid::repliesif it is a reply to a specific post. -
@baris could we theoretically load only top-level replies by:
- filtering
tid::posts(expensive), or - maintaining a separate zset (lighter)?
- filtering
-
Filtering goes
when you have a topic with 50k posts, and adding a new zset means adding 2 actually because there is sort by timestamp and sort by votes for topics. -
I made a post about this a couple of days ago with an example, where I tried to post into a Lemmy community and it didn't arrive
-
@julian did you have a chance to look at this issue of not being able to post into lemmy community?
-
@eeeee If you mean 'post' in the sense that Lemmy means 'post' (i.e. something distinct from a comment), then Lemmy doesn't process User Mentions in those. In a comment, you can Mention your NodeBB user and Lemmy will send it to the relevant instance, but nothing will happen if you Mention your NodeBB user in a post.
-

@freamon
Are you saying that Lemmy is different in that regard?
Example. Im logged into Lemmy and see and interesting post that a friend might be interested in.
I post as a reply
Hey @friend@nodebbinstace look at thisThen it wont notify? How am I supposed to include a friend in a thread?
-
@eeeee Your reply (what Lemmy would term a comment) would go out to friend@nodebbinstance but it would be up to nodebbinstance to resolve what post the comment was a reply to.
To illustrate what I mean about Lemmy and User Mentions in posts, see this post as an example. In the body of that post, the user Mentions 2 people -
[email protected]and[email protected]but neither of those people would have been notified of that post. You can see for yourself by looking at the activitypub representation of that post (by runningcurl --header 'accept: application/activity+json' --location https://lemmy.dbzer0.com/post/39126561 | jq .) and noting that there are no Mentions in the 'tag' section. By contrast, another user Mentions[email protected]in this comment, and she would have been notified of that (you can see that this time there is a Mention in activitypub representation of that coment).@julian For the other direction - as you've found out, Lemmy will first look at 'audience' for a root post and try to resolve it and bail if that doesn't work. If there's no 'audience', it will look in 'cc' to try to find a community and stops when it finds one. It won't look further, so you can't post in more than one community at a time, and you can't use a root post to post in Lemmy community and also notify a Lemmy user of it. It distinguishes between root posts and other posts because the root post is a Note will 'null' for 'inReplyTo'.
