The code snippet you provide below doesn't seem to represent what you say it should. A default class created with an app is the default aspect App.js class, which only has:

```
'use strict';

var App = function() {
  // your app code goes here
};

module.exports = App;
```

Do we mean blade class here? (looks that way!) If so, then let's update it so it reads 'an example of the default blade class created using NodeJS style code'
