Sitecore Compiled Files

Your front end solution compiles into static files (javascript and css) in two different ways.

The Flex Editor

The Flex Editor itself is a single page application. When saving settings or when a front end deploy is manually triggered, static files are generated and deployed to the -fe server.

Public files

Flex generates completely separate public-facing javascript and css files for public consumption. These files include no editing features and only the code necessary to display your components. When saving settings or a front end public deploy is manually triggered, static files are generated and uploaded to your CM's media library under Foundation>Theming>static.

These files are production ready and can be published to your public facing CD server. Note that any server calls in these static files will be hard coded to hit the CD because these are static files that are not context aware.
