Hello its me one and only JaZz
I wanted to know how to make a drop-able website where i can drop picture and it saves to backend in any file like ~/pictures/${user}/jif.png
This article should help you on the frontend
On the backend you will need to create a new Express route which accepts the incoming (uploaded) file then stores it to the disk.
However, I wouldn’t recommend storing the files in your project’s container as they may eat up storage very quickly. Glitch containers/projects only get 200MB of storage each.
