SignalR Skill

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.

Quick Start

Hub Implementation

// Strongly-typed hub with client interface
public class RegisterHub : Hub<IRegisterHubClient>
{
    public async Task SubscribeToRegister(string registerId)
    {
        await Groups.AddToGroupAsync(Context.ConnectionId, $"register:{registerId}");
    }
}
