Defined a mongoose schema in file models/superheroes

A schema is like a blueprint, and it defines what all future heroes will look like. It will be a constructor function we will use to make new superheroes.

npm instal --save ejs

app.set('view engine', 'ejs'); app.set('views', path.join(__dirname, 'views'));

Everything in "client" is a react app, which is separate from the rest of our code. To start the react code base, cd into 'client' and running nmp start.

Everything outside of client is our node-specific app - it only manages our DB and API endpoints. We can startup this project with nodemon or node server.

Each app has it own node-modules and package.json.

We're going to blend the start-up of both apps through a command. To start both simultaneously, use npm run dev. --This command was created in our node package.json.
