Setting up Morgan, express.json & ESLint(airbnb)

1. npm install morgan

2. npm i eslint eslint-config-airbnb-base eslint-plugin-import -g
   a. Although I don't prefer Airbnb style of eslint, since it's industry standard, I'll need to get comfortable with it.

3. const morgan = require('morgan')

4. app.use(morgan('dev'));

5. app.use(express.json());

6. Morgan can show us how long it's taking us to retrieve the data from db
