To do a production build we need to have a terminal opened. We also need to change the directory to the application's root directory and type the following command:

sencha app build

Once the command execution is completed, it will create a new directory called build/NameofTheApp/production. As our application namespace is Packt, it created the build/Packt/production directory as follows:

What this command does is to get all the code we developed (inside the app folder) along with the Ext JS code we need to run the application and put it inside the all-classes.js file. Then, using YUI Compressor, Sencha Cmd will minimize the code and obfuscate the JavaScript code; this way we will have a very small JavaScript file that the user will need to load. Also, Sencha Cmd will evaluate...
