Now, let's write the simple application code to test things out. This app is going to basically connect to our locally running MongoDB server, insert a few records as seed data, and then provide the output on whether or not the data was inserted properly into MongoDB.

You can download a Gist of the code via the URL: http://bit.ly/1JpT8QL.

Using your editor of choice, create a new file named app.js and save it to the application root, which is the testapp folder. Just copy the content of the above Gist on to the app.js file.

//require the mongoClient from mongodb module 
var MongoClient = require('mongodb').MongoClient;
