SignalARRR

CI NuGet npm License

Typed bidirectional RPC over ASP.NET Core SignalR.

Server and client call each other's methods through shared interfaces — with compile-time proxy generation, streaming, cancellation propagation, and ASP.NET Core authorization. Clients available for .NET, TypeScript/JavaScript, and Swift.

Packages

.NET

Package Purpose
Cocoar.SignalARRR.Contracts [SignalARRRContract] attribute + source generator — reference from shared interface projects
Cocoar.SignalARRR.Server Server-side: HARRR hub, ServerMethods, authorization, ClientManager
Cocoar.SignalARRR.Client Client-side: HARRRConnection, typed proxies, event handlers
Cocoar.SignalARRR.DynamicProxy Opt-in runtime proxy fallback via DispatchProxy
Cocoar.SignalARRR.Client.FullFramework Client for .NET Framework 4.6.2+ — typed proxies, streaming, file transfer

TypeScript / JavaScript

npm install @cocoar/signalarrr

Swift (iOS / macOS)

.package(url: "https://github.com/cocoar-dev/Cocoar.SignalARRR.git", from: "4.0.0")

Quick Start

Define shared interfaces, set up the server, and call methods with full type safety:

// Shared interface
[SignalARRRContract]
public interface IChatHub {
    Task SendMessage(string user, string message);
    Task<List<string>> GetHistory();
}

// Client usage — one line to get a typed proxy
var chat = connection.GetTypedMethods<IChatHub>();
await chat.SendMessage("Alice", "Hello!");

// TypeScript client
const history = await connection.invoke<string[]>('ChatMethods.GetHistory');

// Swift client — @HubProxy macro generates the proxy
@HubProxy protocol IChatHub { ... }
let chat = connection.getTypedMethods(IChatHubProxy.self)

For full setup guides, streaming, authorization, and server-to-client calls, see the documentation.

Features

  • Typed bidirectional RPC — server and client call each other through shared interfaces
  • Compile-time proxy generation — Roslyn source generator (zero reflection)
  • Organized hub methods — split logic across ServerMethods<T> classes with full DI
  • Streaming — IAsyncEnumerable<T>, IObservable<T>, ChannelReader<T> in both directions
  • HTTP stream references — file download/upload through SignalR hub methods
  • CancellationToken propagation — server can cancel client operations remotely
  • Authorization — method-level, class-level, and hub-level [Authorize]
  • Server-to-client calls from anywhere — inject ClientManager in controllers, background services, etc.
  • Four clients — .NET, .NET Framework, TypeScript/JavaScript, Swift
  • Typed broadcasts — WithHub<T>().WithGroup().SendAsync<T>() for groups and filtered clients

Framework Support

Target Version
.NET (server + client) .NET 8 / .NET 9 / .NET 10
.NET Framework (client) 4.6.2+ (via Cocoar.SignalARRR.Client.FullFramework)
