Express: Stream an HTML file download from a string in request body

I have a string templateString that is being POSTed to a route in Express. How can this string be streamed as an HTML file and downloaded to the client? 

res.setHeader('Content-type', 'text/html');
res.setHeader('Content-disposition', `attachment; filename=${testname}.html`);

^^ This will force the browser to download.

How to take the string in the request and pipe it to the client in the form of an HTML file?

Just figured it out.. This last simple line seems to work..

res.setHeader('Content-type', 'text/html');
res.setHeader('Content-disposition', `attachment; filename=${testname}.html`);
res.end(req.body.templateString);

I think you can make Buffer form the string and send it via res.end method.

let file = Buffer.from('Your string', 'utf8');

res.writeHead(200, {
    'Content-Type': 'text/html',
    'Content-disposition': `attachment; filename=${testname}.html`,
    'Content-Length': file.length
});

res.end(file);
