When we looked at the creation of a dynamic express site we saw

npm install express-generator -g

If you did it then, you don't have to redo it. The -g flag above looks after that. And remember: You may need to be an administrator to achieve the required permissions. On Linux or OSX this may be done with sudo, on Windows you might need to run cmd in administrator mode.

Now let us create the application

$ express --view=pug nodeOne

   create : nodeOne/
   create : nodeOne/public/
   create : nodeOne/public/javascripts/
   create : nodeOne/public/images/
   create : nodeOne/public/stylesheets/
   create : nodeOne/public/stylesheets/style.css
   create : nodeOne/routes/
   create : nodeOne/routes/index.js
   create : nodeOne/routes/users.js
   create : nodeOne/views/
   create : nodeOne/views/error.pug
   create : nodeOne/views/index.pug
   create : nodeOne/views/layout.pug
   create : nodeOne/app.js
   create : nodeOne/package.json
   create : nodeOne/bin/
   create : nodeOne/bin/www

   change directory:
     $ cd nodeOne

   install dependencies:
     $ npm install

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

Having done that we will set it up to use git as a matter of good habit

cd nodeOne
git init
echo 'node_modules/' > .gitignore
echo 'package-lock.json' > .gitignore
git add .
git commit -m 'initial commit præ festum'

Please notice that the content of the node_modules, the modules we don't write ourselves, is external software, and we don't need it in our repo. It's taken care of via

npm install

We want this app to be hosted, so go to https://www.heroku.com/ and create a free account. When you have done that, install the Heroku Toolbelt, a command line interface. It will prove most useful. Let us do

$ heroku apps:create

And then deploy by

$ git push heroku master

Figure 20.3. The resulting Express Site as Expected

Notice the given URL

So, at this point we have a remotely hosted Node.js app with not much in it. But still.
