OData service using NodeJS and JayData

I am trying to follow this example: http://jaydata.org/blog/install-your-own-odata-server-with-nodejs-and-mongodb but it seems to be out of date, so as written in the example's comment i have update some line of code as follow :

data-model (data-model.js file) :

 $data.Class.define ( 
                        "dbTest.tblTest", 
                        $data.Entity, 
                        null, 
                        {
                            ID: {   type: "id", 
                                    key: true, 
                                    computed: true, 
                                    nullable: false 
                                },
                            Data: { type: "string" }
                        }, 
                        null
                    );

 $data.Class.defineEx   (   "dbTest.Context", 
                            [ $data.EntityContext, $data.ServiceBase ], 
                            null, 
                            {
                                tblTest:    {   type: $data.EntitySet, 
                                                elementType: dbTest.tblTest 
                                            }
                                }                       
                    );

 exports = dbTest.Context;

---

server (server.js file) :

 var c = require('express');
 var bodyParser = require('body-parser');
 var cookieParser = require('cookie-parser');
 var methodOverride = require('method-override');
 var session = require('express-session');
 var errorhandler = require('errorhandler');
 require('jaydata');
 window.DOMParser=require('xmldom').DOMParser;
 require('q');
 require('./data-model.js');
 var app = c();
 app.use(c.query());
 app.use(bodyParser.json());
 app.use(bodyParser.urlencoded({ extended: true }));
 app.use(cookieParser());
 app.use(methodOverride());
 app.use(session({ secret: 'session key' }));
 app.use("/dbTest", $data.JayService.OData.Utils.simpleBodyReader());
 app.use("/dbTest", $data.JayService.createAdapter(dbTest.Context, function (req, res) {
 return new dbTest.Context({name: "mongoDB", databaseName:"test", address: "127.0.0.1", port: 27017 });
 }));
 app.use("/", c.static(__dirname));
 app.use(errorhandler());
 app.listen(8080);

Then when i run this code on Node.js (using mongo db as database) i get this error :

500 TypeError: Cannot read property 'providerConfiguration' of undefined

What i looking for is how to rewrite the example so that it can work.

So the fix for me was to install the mongodb package from npm

npm install mongodb

and also insert some data.
