If I wanted to mess around with ActivityPub c2s clients what's a server I can host that has support for it?
-
@tom I'm slowly working on one, but it's completely unpaid work.
@thisismissem is that related to the stuff you were doing w/ PDSes a few weeks ago or are those separate projects?
-
@tom check if this one I wrote can be of use:
GitHub - mariusor/oni: Single user ActivityPub instance with minimal fuss. (mirror repository)
Single user ActivityPub instance with minimal fuss. (mirror repository) - mariusor/oni
GitHub (github.com)
PS: Any feedback about setting it up and configuring it for your use case will be appreciated, either here, or on github/mailing list.
mariusor@metalhead.club is there a public instance available?

@tom I see others are pointing you in a similar direction, but funnily enough I tinkered with Social Web's ap-component test instance this afternoon!
Look at the sample client "acct-handler", too. That's what I tried today.
ap-components
I want to share some information about a repository we just published. ap-components is a set of Web Components for building interfaces for the ActivityPub API. I built it as I was making a sample application for handling the acct: URI scheme. I found myself making more and more components for the UI, and realised…

@tom yeah, activitypds is the research project name, but there's a bunch of upstream work in Fedify to enable C2S in Fedify, and then also to enable reusing the Fedify vocabularies (they take JSON-LD and convert into classes that Fedify understands, and handles serialisation to JSON-LD)

@tom basically the things I'm trying to solve in ActivityPDS are:
- an OAuth profile (based on AT Proto's OAuth profile)
- webfinger & DIDs & Handles
- what should a "PDS" do in the context of ActivityPub C2S, how much logic does it implement, or is it just a simple pipe? -

@tom I can also send you an invite code.
There's a chapter on the social API in the ActivityPub book.

@tom there's a discussion here
Which ActivityPub applications support Client-to-Server (C2S)?

@mariusor I got it running w/o many issues (maybe I missed it but I didn't see any wiki pages on building Box? I got that working as well regardless)
Is there an active issue w/ fetching oni content in Mastodon? I can't seem to grab my user or any statuses from my server or from activitypub.academy. I also tried fetching your posts (because it sounded like it at least worked last year, https://metalhead.club/@mariusor/113708953874760675) but that didn't work either so maybe I'm missing something.
@tom I basically follow actors and that's how seeing posts by others in your /inbox works.
The frontend loads stuff directly through JavaScript fetch and needs all the mechanisms of that to work (and I imagine what you see might be things failing to load due to CORS rules being too restrictive on remote Mastodon instances)
I am not aware of any issues with receiving activities though, and in this process the objects themselves should be fully dereferenced to local copies.
I'll add a note about BOX compilation. Thanx.

@tom looking at the post of mine you linked, I realize you're probably thinking of regular object discovery, and there isn't any mechanism for it yet, or for viewing remote objects that haven't reached your inbox.
-
@julian yes, two of them:
https://rattlehead.bruta.link < where a bot posts daily metal releases scraped from the internet
https://marius.federated.id < where I write a bit about stuff and play with more expressive ActivityPub objects.

@mariusor sorry I meant the reverse behavior, viewing Oni users/activities from my mastodon instance (or from mastodon.social) not viewing remote activities from oni
I.e. searching for https://marius.federated.id/outbox/1725894299052/object doesn't pull up the object in mastodon (and searching for the user doesn't bring that up either)

@mariusor actually nevermind ignore me, searching for your federated id user seems to work so I must have something wrong with my network configuration, I'll do some debugging later

@tom I understand.
Indeed in the past two/three weeks I must have deployed something (or Mastodon made some changes) that regular objects posted by ONI aren't findable any more. The problem is that I don't have a development setup for mastodon on which to test what the problem is.
However the actors should still be available.

@tom a quick check list for you:
1. Check if the actor is publicly accessible from the internet.
2. Check if it has a RSA private/public key.
3. Check that if you have a proxy in front of ONI it doesn't mangle Accept/Vary/Content-Type headers.
4. Check that if you have a proxy the `/.well-known/webfinger` route is handled by ONI. (your proxy should forward all routes to ONI directly as a start)

mariusor@metalhead.club Can you use ActivityPub.academy? There is a logger built in so you can see the activities coming and going. It might help you debug why the ONI activities aren't being processed.
