If you use Express as a web server, then:

expressServer.post('/', function (req, res) {
  fs.readFile(req.files.inputFieldName.path, function (err, data) {
  // inputFieldName - имя input в форме
  var newPath = __dirname + "/uploads/uploadedFileName";
  fs.writeFile(newPath, data, function (err) {
    res.redirect("back");
  });
});
});
