SocketIOClient-Unreal is a Socket.IO client plugin for Unreal Engine that enables real-time bidirectional communication between Unreal applications and Socket.IO servers. The plugin features a modular architecture with separate modules for core client functionality (SocketIOClient), low-level Socket.IO implementation (SocketIOLib), JSON handling (SIOJson), and utility functions (CoreUtility). It provides both Blueprint-accessible components (USocketIOClientComponent) and native C++ interfaces (FSocketIONative) for flexible integration. The plugin handles connection management, event emission/reception, namespaces, rooms, and includes sophisticated JSON-UStruct conversion utilities with Blueprint compatibility.
