Odds are if you’ve landed here you’re aware of what Paperclip is and the purpose it servces within a Rails application. If not, it’s basically a gem that will handle file uploads. In my case I use it for resizing images, saving them somewhere (S3), then easily presenting them back to the user inside of a view. Note: This tutorial should work with any S3 compatible object storage API. Minio is just one of the more common ones.
