create file for download on the fly within POST request

I am trying to figure out, if its possible to create a file without storing it in the drive, for only purpose to download it right away within POST request.

const specialRequests = async (req, res, next) => { // POST request
    ... // processing
    let xmlString = ... // get processed xml string

    // create xml file from that xmlString 
    // initialise download of the file, dont save it
    let file = ???
    res.download(file);
};

If its possible how it can be done

The download method is explicitly designed to transfer "the file at path".

You can create a download with some data, but you can't use that method.

res.set('Content-Type', 'text/xml');
res.set('Content-Disposition', 'attachment; filename="example.xml"')
res.send(xmlString);
