Creating the Shopping Cart Server

With the model defined, you can begin implementing the shopping cart server. Listing 28.7 implements the Express server for the shopping cart application. This code should be familiar to you. It includes the express and mongoose libraries and connects to MongoDB via Mongoose.

Notice that there is a require statement for the model definition to build the Schema object within Mongoose. Also, the ./cart_routes file is included to initialize the routes for the server before listening on port 80.
