description: Real-time communication patterns with Action Cable and Trailblazer Operations. Use when implementing WebSocket channels, broadcasting updates, or handling real-time features. Covers channel organization, authorization, messaging patterns, and operation broadcasting.

Realtime (Action Cable + Trailblazer 2.1)

Dependencies

  • •actioncable
  • •trailblazer-operation
  • •trailblazer-rails

Channels Organization (Pattern)

  • •app/channels/ hosts channel classes
  • •One channel per domain concept (game/room)
  • •Authorization happens in subscribed
  • •Use stream_for with domain instances
  • •Keep channels thin and delegate logic to Operations

Messages (Pattern)

  • •JSON payloads with type and small deltas
  • •Include timestamps in broadcasts

Operations Broadcasting (Pattern)

  • •Broadcast inside Operations after successful state changes
  • •Example: Game::BroadcastChannel.broadcast_to(game, { type: 'player_moved', ... })

See Channels for requirements.
