Error invalid login in recent update

I faced problem with the recent update. There is no server.js file in the module folder. My site is c:/wamp/www/testsite and module directory of nodejs is - c:/wamp/www/testsite/sites/all modules
Now, since so many things have changed in the recent nodejs module structure, I am having a hard time in configuring it properly so that node.js could integrate with my testsite properly.
I did as per readme guidelines:
1. Install drupal-node.js packge with npm: npm install drupal-node.js (Make sure to do this outside of your Drupal modules directory)
Hence I did it in mytestsite/sites directory - which created a folder - node_modules/drupal-node.js inside which there are many files and folders including another node_modules folder containing modules like express, request, socket.io etc.
2. Point Drupal at the Node.js server process, either using the configuration page or settings.php.
I opted to use the configuration page, visited '/admin/config/nodejs/settings', and entered
the appropriate values.

backendSettings = {
"scheme":"http",
"host":"localhost",
"port":8080,
"key":"/path/to/key/file",
"cert":"/path/to/cert/file",
"resource":"/socket.io",
"publishUrl":"publish",
"serviceKey":"",
"backend":{
"port":80,
"host":"localhost",
"messagePath":"/testsite/nodejs/message"},
"clientsCanWriteToChannels":true,
"clientsCanWriteToClients":true,
"extensions":[],
"debug":true,
"transports":["websocket", "polling"],
"jsMinification":true,
"jsEtag":true,
"logLevel":1};

After that I opened node.js command prompt and cd to c:\wamp\www\testsite\sites\node_modules\drupal-node.js
and typed - node app.js which started - http server - but threw many errors also like invalid login for uid undefined.
What step did I miss? What is right configuration ? There must be some proper guidelines to do so. Please help.
