Cocoar.SignalARRRTyped Bidirectional RPC

Call server and client methods through shared interfaces over ASP.NET Core SignalR — with compile-time proxies, streaming, cancellation, and authorization.

Why SignalARRR?

Shared Interfaces

Define contracts once, use them on both server and client with full IntelliSense.

Compile-Time Proxies

Roslyn source generator produces typed proxies at build time — zero reflection, AOT-friendly.

Bidirectional RPC

Server calls client, client calls server — both directions through the same typed interface pattern.

Item Streaming

IAsyncEnumerable, IObservable, and ChannelReader — send sequences of items in both directions with cancellation support.

Large File Transfer

System.IO.Stream parameters are transparently routed through HTTP — transfer multi-GB files through a normal RPC call.

Authorization & Token Refresh

Authorization inheritance across ServerMethods classes with automatic token challenge/refresh on expiry.

Multi-Platform

.NET server and client, TypeScript/JavaScript for browser and Node.js, and native Swift for iOS/macOS.
