signalr

SKILL.md

ASP.NET Core SignalR implementation for real-time client-server communication. Sorcha uses two hubs: ActionsHub (Blueprint Service) for workflow notifications and RegisterHub (Register Service) for ledger events. Both use group-based broadcasting with JWT authentication via query parameters.

| Groups | Route messages to subscribers | wallet:{address}, register:{id}, tenant:{id} | | Typed Hubs | Compile-time safety | Hub | | IHubContext | Send from services | Inject IHubContext | | JWT Auth | Query parameter auth | ?accesstoken={jwt} |
