Summary

It looks like when I query any community outbox it only returns the first 50 posts and it doesn't offer any form of pagination.

The endpoint should at least provide the right number for totalItems and give a full count of the activities created by the community. But to make it easier to comply with other AP software, it should be able to provide the full list of activities through pagination.

Steps to Reproduce

[
  "@context",
  "id",
  "orderedItems",
  "totalItems",
  "type"
]

$ curl https://lemmy.ml/c/lemmy_support/outbox -H 'accept: application/activity+json' | jq '.totalItems'
50

Not a bug, this is simply not implemented yet.

Come to think of it, there are two separate issues. Pagination is indeed an enhancement, but I would argue that "totalItems" already returning 50 is an actual bug. Should I create a separate issue for it?

[Nutomic]

50 is the number of items in the Activitypub collection. It could be changed to show the total number of posts, but the spec is not really clear to me which one is correct.

Personally speaking, until there is proper pagination I'd rather just get the total count and not actual lists, than a limited view of the collection and no "factual" information.
