@arj here's what I've found ahau is using sofar which we'll need to migrate. As expected, it's mostly ssb-tribes functionality:

ssb-tribe

• mutations

  • create
    • publishes a group/init (includes groupKey), persists groupId, groupKey, authors
    • can also mint a poBox for the group, publishing a group/po-box msg
  • subtribe.create - creates a new group and links it to another with a link/group-group/subgroup msg
  • invite - publishes a group/add-member message
  • link.create - links your feed to a group with link/feed-group msg to set up a "personal group"

• queries (use ssb.query.read)

  • list - list all tribes you have keys for
  • poBox.get - looks up the current poBoxId connected to a groupId
  • findSubGroupLinks - look up links from a group to subgroup(s)
  • subtribe.findParentGroupLinks - look up links from a group to parentGroup(s)
  • findByFeedId - look up groups that have been linked to a feedId

• encryption

  • box/unbox P.O. Box messages (the new DM on the block)

• listeners (use ssb.messagesByType)

  • new group/add-member msgs - triggers groupId/Key registration, rebuild
  • new group/po-box msgs - triggers poBoxId/Key registration, rebuild

ssb-ahau (graphql api)

• using ssb.query.read to list all sorts of records
• listener on new messages to invalidate record cache
• using ssb.status (or progress) to display in UI if rebulding/ indexing for a long time

ssb-profile

• find method contains a flumeview-search index over profile preferredName, altNames fields
