formidable
Your favorite multipart/form-data module now simpler, smaller, faster, and more specification & Web-compliant.
You may soon see it as just formidable v4 or something.
It uses formdata-polyfill and fetch-blob.
It does NOT write anything to disk or storage. You are given just FormData and you can do it whatever you want, however you want.
Turn it into stream and write to disk? OK, no problem. Uploading to S3? OK, no problem.
