multer-s3-transform

multer-s3-transform v2.10.3 is a streaming multer storage engine for AWS S3, extended from multer-s3 with support for file transforms before upload. It avoids buffering entire files to disk by streaming multipart uploads directly to S3. Releases are irregular; it is a maintained fork of the original multer-s3. Key differentiators include transform support and ongoing updates.
