Connecting our project

Now we know what we're doing, let's connect our project to a database using the default Mongoose connection.

Creating the connection

For the sake of well organized code, let's create a folder called model, and in that, an empty JavaScript file called db.js. We'll use this for managing the Mongoose connection, and will add to it in later chapters.

At this stage the file needs to do three things:

1. Bring in the Mongoose module

2. Build the connection string for the database

3. Open the Mongoose connection to the database

So in your /model/db.js file, enter the following:

// Bring Mongoose into the project
var mongoose = require( 'mongoose' );

// Build the connection string
var dbURI = 'mongodb://localhost/MongoosePM';

// Create the database connection
mongoose.connect(dbURI);

Each of the three objectives is achieved with just one line of code—pretty simple don't you think!

Catching the events

Next up we want to set up our event handlers. At this stage, we are just going to log messages...
