Is it for uploading file/s/folder/s from a user's machine through the browser to huggingface and for same thing but backend? I'd like to know more about this task if possible 🤠

I guess backend it would take a {path: string} to the folder or to the file for NodeJS, and frontend it would take a File or FileSystemEntry (to handle folders) as param.

gitignore'd files should also be ignored in the case of a folder.

It would be a wrapper around commit, but would require changes to commit as well or at the very least adding a smart Blob wrapper (like Bun) around files.

This is going to be a Technical PR
