javascript - How do I send a jdenticon without storing it on the server using express.js?

Question

What I'm trying to do is create a small API to generate jdenticons and deliver them as pngs. They shouldn't be stored on the server. My code

app.get("/api/avatar/:name", (req, res) => {
  let img=jdenticon.toPng(req.params.name, (isset(req.query.size)?req.query.size:64));
    res.sendFile(img);


});

gives an error because img isn't a path. So how do I convert the Jdenticon to a file and send it?
