SignalRConnect — architecture & feature overview

Overview

SignalRConnect connects to ASP.NET (Core) SignalR hubs, invokes methods, and handles incoming messages. Values are passed via a typed wrapper; helpers build and validate hub URLs.

Fork note Two modules (SignalR, SignalRBlueprint) were renamed to SignalRConnect* for UE 4.27–5.0+, with Microsoft protocol strings preserved. UE5-only double nodes were made C++-only and URL helpers added; the Blueprint module now links the HTTP module.

Installation

  1. Copy the SignalRConnect folder into your project's Plugins/ directory.
