Building an Express Application Chapter 2

app.listen(3000, function() { console.log('listening on 3000') })

module.exports = app;

Now, run the following command:

$ node app.js

This will spin up our application server. Now, when we go to the
http://localhost:3000/ URL, we should be able to get this:

That's it. We have successfully created an Express application.
