What happens when you edit a file in Heroku?
If you edit files present in a Heroku dyno, the edited file comes back to its initial state after some time. This is because Heroku restarts the dynos randomly for keeping them in good health.

How to create a slug archive in Heroku?
The created folder will contain a directory called app which contains the generated source code and a slug.tar.gz file, which is the compressed version the source code.
