How to work with files with a Heroku based web app

Heroku dyno filesystems are ephemeral, non-persistant and not shared between dynos. So when you do heroku run bash, you actually get a new dyno with a fresh deployment of you app without any of the changes made to ephemeral filesystems in other dynos. So, to be able to manage files on web using Heroku you have to resort to other solutions. See a couple in the note details…

  • Add the files in your local file system and commit them to git. Pros: this is a permanent solution. Cons: Is not the simplest one.
  • Create an upload, download service to manage files. For Heroku this is effimeral.
  • Use a third party service to manage files.
  • Firebase
  • AWS
  • Github
