Summary

This chapter has configured the Ext JS 4 development environment and introduced practical design conventions and concepts. We have installed Sencha Cmd and generated the 3T application skeleton, examining the core generated files to understand the recommended application structure. Our model entities have been generated using Sencha Cmd and are ready for enhancement in the following chapters. The scene has been set for building our 3T application frontend.

In Chapter 10, Logging On and Maintaining Users, we will develop the Ext JS 4 components required to log on to the 3T application and maintain users. Our creative journey through User Interface (UI) design is just starting!
