How to configure AppJS to work with node-http-proxy server

I'm trying to get node-http-proxy working with AppJS. Unfortanly it crashes on launch of the app. What I did:

• Download & extracted AppJS from http://appjs.com/;
• Installed node-http-proxy with npm install http-proxy;

• Edited the app.js window.on(create) function:

  window.on('create', function(){
  console.log("Window Created");
  window.frame.show();
  window.frame.center();
  window.frame.setMenuBar(menubar);
  
  var http = require('http'),
  httpProxy = require('http-proxy');
  // 
  // Create your proxy server and set the target in the options. 
  // 
  httpProxy.createProxyServer({target:'http://localhost:9000'}).listen(8000);
  
  // 
  // Create your target server 
  // 
  http.createServer(function (req, res) {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.write('request successfully proxied!' + '\n' + JSON.stringify(req.headers, true, 2));
    res.end();
  }).listen(9000);
  });
  

When the app starts I want to start the nodeJS proxy server. Is it possible to connect from a external PC to this proxy server? (I know I will need to open ports for this)

For example if I run the app on my home PC and at work I will set the proxy settings of the work PC to homePC_IP:8000. Will this work?

Haven't got a fix for the crash of node-http-proxy but I instead I used https://github.com/TooTallNate/proxy and this works like a charm!
