To install Mongoose, we will use NPM. So, in your Terminal, navigate to the wc-backend project and run the following command:

$ npm install --save mongoose

Once the installation is done, we need to get into the src folder and create a new folder called config. In the config folder, now create a new file called mongoose-connection.js:

$ cd src
$ mkdir config
$ touch config/mongoose-connection.js

Now that we have Mongoose installed and we have created our configuration file, it is time to write some code to establish the connection to MongoDB.
