We will be using a similar modular file and folder structure as seen in the previous chapter. Initially, we will create the following folders and files:

• controllers: This folder will house the files that will contain our application's main business logic.
• middleware: This folder will contain all our custom middleware.
• models: This folder will contain our data objects and mongoose schemas.
• views: This folder will contain the template files for our application.
• index.js: This is the entry point for our application. Here, we will initialize the application, register all the required middleware, and start the server.
• db.js: This is where we will connect to our MongoDB database using Mongoose.

To create the needed folders, you can run the following command in the terminal:

mkdir controllers middleware models views

To create the needed files, you can run this command in the terminal:

touch index.js db.js

After initializing the project, installing the needed dependencies, and creating the required files and folders, we should have the following structure:

├── controllers
├── db.js
├── index.js
├── middleware
├── models
├── package-lock.json
├── package.json
└── views
