server.js

// Use a Node and Express Web Server;
// Be backed by a MySQL Database an ORM (not necessarily Sequelize);
// Have both GET and POST routes for retrieving and adding new data;
// Be deployed using Heroku (with Data);
// Utilize at least one new library, package, or technology that we haven’t discussed;
// Have a polished frontend / UI;
// Have folder structure that meets MVC Paradigm;
// Meet good quality coding standards (indentation, scoping, naming).
// Must not expose sensitive API key information on the server, see Protecting-API-Keys-In-Node.md
