auto reconnect websocket on close event

[thunderace]

It's a workaround for unexpected websocket close.

I believe close event is triggered when the Browser's window is actually closed. I rarely witnessed Websocket is closing abnormaly. Did you investigate further? Why is your websocket comm is failing?

Simple ping-pong can be implemented.

Client side:

function ping() {
	websock.send("{\"type\":\"ping\"}");
}

var ping = setInterval(ping, 10000);

if (json.type === "pong") {
	console.log("Server is alive.");
}

Server side:

if (obj.type === "ping") {
        console.log("Got ping from client.");
	var pong = {type: "pong"};
	wss.broadcast(pong);
}
