The generation game

From here, we can quickly build out the skeleton of our application. The key MVVM classes are controllers, models, and views (with their associated view controllers and view models). Sencha Cmd can assist with quickly creating all of these classes.

Note

The generation of code using a command-line tool is often known as "scaffolding" and was popularized by Ruby On Rails. For more on the subject, refer to http://en.wikipedia.org/wiki/Scaffold_(programming).

For controllers, it's simple:

sencha generate controller MyController

The preceding command produces:

// app/controller/MyController.js
