	r := http.NewServeMux()
	r.HandleFunc("/ws", wsServer.Handler)

	wsServer.On("echo", func(c *websocket.Conn, msg *websocket.Message) {
		_ = c.Emit("echo", msg.Data)
	})

	_ = http.ListenAndServe(":8080", r)
}

	r := http.NewServeMux()
	r.HandleFunc("/ws", wsServer.Handler)

	ch := wsServer.NewChannel("test")
	wsServer.OnConnect(func(c *websocket.Conn) {
		ch.Add(c)
		ch.Emit("connection", "new connection come")
	})

	_ = http.ListenAndServe(":8080", r)
