use file instead of path to file string

[conor909]

I have a node script that generates a PDF file, and I want to pass the file directly to be converted instead of saving the file to disk and giving a path to file

Why is saving it in a temporary directory not an option? :)
If your generated file is a stream for example you can simply use fs.createWriteStream to write that stream to a temporary file.
