GWS
Simple, fast, reliable websocket server & client
...The library exposes a minimal event-driven API, allowing developers to build WebSocket applications with relatively little code. It supports standard TCP usage as well as WebSocket operation over KCP and Unix domain sockets. GWS also includes practical features for connection handling, compression, heartbeat management, UTF-8 validation, and scalable read or write loops. It is a strong fit for Go developers who need a lightweight but feature-complete WebSocket foundation for real-time applications.
