Extract One page of a complex application

We at our company have a complex Angular Typescript Less Application. For demo purposes I need to extract one page of the application. This is very hard, since we have so many services, controlles, Less and CSS-Files which have dependency to that page. What would be the easiest way to do that, to only get the used Javascript and CSS?

EDIT: The page is actually a styleguide which needs to get distributed and normalized. So I don't want to forward the whole application source-code, just one html-file with one Javascript (where only the code which is needed is inside it) and only the used CSS. This would be best-case. I know it's hard to accomplish but maybe there's some kind of trick.
