ReferenceError: WebSocket is not defined

[CrazyFlasher]

What I've missed?
Code

import hx.ws.WebSocket;

class Ws
{
    static public function main()
    {
        var ws:WebSocket = new WebSocket("ws://127.0.0.1:3001");
    }
}

Build

haxe -js client.js -main Ws -debug -cp src -lib hxWebSockets

Run

node client.js

Error

Adding this line resolved the issue:

        #if js
        untyped global.WebSocket = require("ws");
        #end

Is this when running it within node?

[CrazyFlasher]

Yes. I run it on NodeJS for unit testing.
