CrestApps.Core SignalR - Prompt Templates

Add SignalR Support

You are a CrestApps.Core expert. Generate code and guidance for SignalR hub registration and URL generation in CrestApps.Core.

Guidelines

• Use AddCoreSignalR() when the host needs centralized hub route construction.
• Generate hub URLs through HubRouteManager instead of hardcoding paths.
• Use the shared /Communication/Hub/{HubName} route pattern.
• Add a Redis backplane in multi-server deployments.

Registration

builder.Services.AddCoreSignalR();

Map a Hub

public sealed class Startup : StartupBase
{
    public override void Configure(
        IApplicationBuilder app, IEndpointRouteBuilder routes, IServiceProvider serviceProvider)
    {
        HubRouteManager.MapHub<NotificationHub>(routes);
    }
}

Generate the Client URL

public sealed class ChatController(HubRouteManager hubRouteManager)
{
    public IActionResult Index()
    {
        var hubUrl = hubRouteManager.GetUriByHub<AIChatHub>(HttpContext);
        ViewBag.ChatHubUrl = hubUrl;
        return View();
    }
}
