I'm in a situation where I have react client sending me audio data in form of mp3 file. I want to save these files to s3 bucket. I have been searching for any direct method which is available at server side so that I don't have to store file locally at server and file should directly upload to S3. In case of using multer file has to be saved locally at server and then upload to s3. If there is any direct method available please suggest.
