SignalR Tunnel

Transport injection for ASP.NET Core SignalR

Server Usage

FlyByWireless.SignalRTunnel

Named Pipe

// Runs a light weight SignalR server without HTTP
using var app = Host.CreateDefaultBuilder().ConfigureServices(services =>
    services.AddSignalR()
        .AddMessagePackProtocol()
        .AddNamedPipe<MyHub>("My Hub", maxNumberOfServerInstances)
        .AddNamedPipe<AnotherHub>("Another Hub", maxNumberOfServerInstances)
        //.AddMyQuicStream<MyHub>(MyQuicStreamType.MyHub, roles: "admins,managers")
).Build();
app.Run();

Custom Stream / IDuplexPipe

Refer to source code of FlyByWireless.SignalRTunnel.NamedPipeServer<THub> or FlyByWireless.SignalRTunnel.Test.

An authenticated user may be set during OnConnectedAsync() to use the [Authorize] attribute on hub methods.

Client Usage

FlyByWireless.SignalRTunnel.Client

Named Pipe

await using var client = new HubConnectionBuilder()
    .WithNamedPipe("My Hub"
        //, serverName: "."
    )
    .Build();
// TODO: register event handlers
await client.StartAsync();
// TODO: invoke methods
await client.StopAsync();

Custom Stream / IDuplexPipe

var stream = myQuicConnection.OpenBidirectionalStream();
await stream.AuthAsync("admin", "password");
await using var client = new HubConnectionBuilder()
    .WithTunnel(stream)
    .Build();
// TODO: register event handlers
await client.StartAsync();
await Task.Delay(1); // avoid race condition
// TODO: invoke methods
await client.StopAsync();
