This recipe will be focused on showing the integration of Mongoose with ExpressJS using what was seen in previous recipes. First, ensure that you have MongoDB installed and it's running. As an alternative, if you prefer, a MongoDB DBaaS instance in the cloud will also do. Before you start, create a new package.json file with the following code:

      { 
        "dependencies": { 
          "body-parser": "1.18.2", 
          "connect-mongo": "2.0.1", 
          "express": "4.16.3", 
          "express-session": "1.15.6", 
          "mongoose": "5.0.11", 
          "node-fetch": "2.1.2" 
        } 
      } 

Then, install the dependencies by opening a Terminal and running this code:

npm install
