Answer 1

There are probably various ways to do this, but what works for me is to minify before pushing. Then I use a subtree to keep my build files separate from the "source" files. So, for example, if you build to a folder called "dist", you can push to a subtree called heroku/master like this:

git subtree push --prefix dist heroku master

Just don't forget to ensure that the dist folder is not ignored (it often is, by default) - so edit your .gitignore file accordingly.

The --prefix command ensures that the dist folder effectively becomes the "root" folder from the point of view of that branch.
