fixed the issue. Will look into that further I found what was crashing my server (it took me some time because I was lately focusing on the client programming, it is today when I returned to the server programming). As @Moo-Juice suggested, it is a problem related to accessing the UI. In fact here is the scenario that was causing the crash:
The server starts It enters into an infinite loop listening for clients to connect. This infinite loop is in the backgroundWorker. A client connects to the server. I print a message on a textBox that a client has connected. //here is the problem To be able to establish point (4) I am using the backgroundWorker.ReportProgress method.
code :
private void PrintString(string stringToPrint)
{
    var myForm = Form1.ActiveForm as Form1;
    myForm.backgroundWorker1.ReportProgress(1, stringToPrint);
}
private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    textBox1.Text += (string)e.UserState;
    textBox1.Text += Environment.NewLine;
}

To fix the issue you can do Well I don't know what's wrong with AppFog, but I created an app and ran this code at Nodejitsu and I can confirm it works in Chrome @ Android 4.1.2: http://testforso.jit.su/

Hope that helps This question is half about my code specifically, and half about the high-level view of actually getting data for a particular user from a node API. ,
Is this the correct idea?
code :
app.use(function (req, res, next) {
  var token = req.signedCookies.token
  res.locals.user = jwt.verify(token, 'my-secret')
  next()
})

like below fixes the issue If you look at the end of the documentation you cited, you will notice that the request is:
code :
GET https://api.tradegecko.com/products
myRouter.route('/testRoute')
  .get(function(req, res){
    request({
      method: 'GET',
      uri: 'https://api.tradegecko.com/products',
      headers: {'Authorization': 'Bearer ' + 'TOKEN HERE'}
    }, function (error, response, body){
      if(!error && response.statusCode == 200){
        res.json(body);
      }
    })
  });

may help you . For that you should use the standard NodeJS environment variable - NODE_ENV.
It should be set to development on your local machine. And on your production server it is usually defaulted to production, as it is on Heroku: NODE_ENV=production
