Viewing the app using your web browser

In order to run the web app, you need to turn your /www folder into a web server. Again, there are many methods to do this and people tend to stick with one or two ways to keep things simple. A few other options are unreliable, such as Sublime Text's live watch package or a static page generator (for example, the Jekyll and Middleman apps). They are slow to detect changes and may freeze your IDE, so won't be mentioned here.
