changing reaction add/remove or the reactions table

Reactions

Emoji reactions are a (message_id, user_id, emoji) triple. One reaction per user per emoji per message.

Endpoints

POST   /api/messages/{message_id}/reactions
DELETE /api/messages/{message_id}/reactions/{emoji}

POST body: {emoji}. Both endpoints require workspace membership for the message's workspace. Adding twice is a no-op (INSERT OR IGNORE); removing a missing reaction is a no-op.

Events

  • reaction.added on add
  • reaction.removed on remove

The event payload contains {message_id, emoji} and inherits the message's channel_seq so that reaction counters can be ordered alongside the message they decorate.

Storage

Reactions are stored verbatim — there's no allowlist or canonical shortcode table. Pass any string the UI is willing to render. Crustacean reactions like :lobster: and :claw: are intended in the reaction pack but not enforced server-side.
