This app interacts with a MySQL database called orinoco_DB. A schema file is included for creating the database and two tables: products and departments. There are two insert commands that will populate the tables with 70+ products and 4 departments.
The app requires the nmp module [mysql].(https://www.npmjs.com/package/mysql) to handle the database queries.
The user's MySQL password in kept protected in a .env file which is in turn handled by the npm module [dotenv].(). The user should add a file named .env and it add a line 'MYSQL_PASSWORD=********' where ******** is the user's password.
The app also uses these modules to format the user interface:
[cli-Boxes].(https://www.npmjs.com/package/cli-boxes) - for border boxes
[colors].(https://www.npmjs.com/package/colors) - for colored output
[inquirer].(https://www.npmjs.com/package/inquirer) - for all menus
[columnify].(https://www.npmjs.com/package/columnify) - to format listings in the manager app.
