Post Description

I was tired setting up file uploads for multiple projects with bloated aws-sdk so built my own, my first attempt was next-s3-uploader, it worked but needed much better developer experience and wanted to get all benifits of typesafe Typescript, and wanted to have a very light weight toolkit that can do all things a dev needs to manage s3.

Credits to `aws4fetch` which made it be able to run in edge enviornments and cloudflare workers, now im trying to expand and build towards non Reactjs frameworks too and have support.

Setting up file uploads shouldnt be hard, but is. the easier options have vendor lockin's.

So made a DX friendly, typesafe file upload library, enjoy. Happy to discuss any improvements and options.
