Creating the Notes application

Since we're starting a new application, we can use the Express generator to give us a starting point. It is not absolutely necessary to use this tool since we can definitely write the code ourselves. The advantage, however, is that it gives us a fully fleshed out starting point:

$ mkdir notes
$ cd notes
$ npx [email protected] --view=hbs --git .
destination is not empty, continue? [y/N] y

   create : .
   create : ./package.json
   create : ./app.js
   create : ./.gitignore
   create : ./public
   create : ./routes
   create : ./routes/index.js
   create : ./routes/users.js
   create : ./views
   create : ./views/index.hbs
   create : ./views/layout.hbs
   create : ./views/error.hbs
   create : ./bin
   create : ./bin/www
   create : ./public/stylesheets
   create : ./public/stylesheets/style.css

   install dependencies:
     $ cd . && npm install

   run the app:
     $ DEBUG=notes:* npm start

   create : ./public/javascripts
   create : ./public/images
$ npm install...
