How do you load Photon lib in node environment? It should be something like this:
load("Photon-Javascript_SDK.js"); s

Also, js sdk relies on browser's WebSocket object, So you need to implement its interface with websocket you use in nodejs. Like this:


// adapter for browser websocket
var wsClient = require("ws")
WebSocket = function (uri) {
	var self = this;
	this.socket = new wsClient(uri, {protocol: "Json"});
	this.socket.onopen = function () {
		self.onopen();
	};
	this.socket.onerror = function (error) {
		self.onerror(error);
	};
	this.socket.onclose = function (ev) {
		self.onclose(ev);
	};
	this.socket.onmessage = function (message) {
	if (message.type === 'message') {
		self.onmessage({data:message.data});
	}
	return true;
};
