To handle FormData with Node.js Express.js 4, we can use multer.

npm i multer

Then we use it by writing

const multer = require("multer");
const upload = multer();

app.post("/send", upload.none(), (req, res) => {
  const formData = req.body;
  console.log("form data", formData);
  res.sendStatus(200);
});

to call multer to return the upload object.
