QA/Prod Configuration

Hi All,

What are the standard or best practices for storing configuration for dev, QA and Production in Sencha Touch? For instance, I have a different AJAX Host, Logging Settings, and resource files for each environment so I need that to change when being used in each environment. Can I have a build for local, QA and Production that would use the proper settings for my Host?

For now, I have created three files: local, dev and production and load the proper one when the app starts up. But, thought I might be missing something with how Sencha Touch handles this.

Thanks,

Chris
