Class Method Details

.create(client, did:, text:, reply: nil, created_at: Time.now.utc.strftime("%Y-%m-%dT%H:%M:%S.%LZ")) ⇒ Object

Compose a record for com.atproto.repo.createRecord (app.bsky.feed.post). When ‘reply` is provided, both root and parent are set to the same target. This is correct for top-level replies and a known v1 trade-off for replies deeper in a thread (AppView will nest the reply under `parent` instead of the original conversation root).

      collection: "app.bsky.feed.post",

    },
  )
end

.detect_link_facets(text) ⇒ Object

Scans ‘text` for bare URLs and builds AT Protocol link facets pointing at each match. Without this, the AppView treats URLs as plain text and does not render them as clickable links.
