From NodeJS Buffer to S3 file

Question

I have a buffer returned by an API call containing file data however when I try to S3.Upload() or fs.write() the file is corrupt for anything except PDFs (png, jpg, .doc, .docx are the key types I need). For PDFs I just use the binary data as it comes in (fs.writeFile('myFile.docx', myBuffer)) but I've also tried:

• fs.writeFile('myFile.docx', myBuffer.toString('base64')),
• fs.writeFile('myFile.docx', myBuffer.toString('utf8')),
• fs.writeFile('myFile.docx', myBuffer.toString('binary'))

I'm sure it's to do with encoding the binary from the buffer but I've reached the limit of my knowledge with the above attempts.

Answer 1

It turns out that my method for dividing the data stream was leaving a trailing /r/n on the end of each file, PDFs don't seem to mind, everything else does.
