We've just released a package for that at https://github.com/thousandxyz/s3-lambo, fully tested. You can use the code or the package at your need.

I fixed few minor errors with paths / other things and
published this as a package

https://www.npmjs.com/package/s3-upload-folder/v/latest

the source (MIT)

https://github.com/Prozi/s3-upload-folder/blob/main/index.js

uses standard S3 sdk authentication (need to read about this if you don't know what I mean)

enjoy!
