Access golang websocket server with clientjs client node

I am new to NodeJS. Suppose I have an echo server implemented with the Golang web package package:

package main

import (
    "code.google.com/p/go.net/websocket"
    "log"
    "net / http"
)

func EchoServer (ws * websocket.Conn) {
    var msg string
    websocket.Message.Receive (ws, & msg)
    log.Printf ("Message Got:% s \ n", msg)
    websocket.Message.Send (ws, msg)
}

func main () {
    http.Handle ("/ echo", websocket.Handler (EchoServer))
    err: = http.ListenAndServe (": 8082", nil)
    if err! = nil {
        panic (err.Error ())
    }
}

What does nodejs client code look like?
