app.post('/', function(req, res){    
    console.log(req.body.**NAMEATTRIBUTE**);
    res.send(req.body);
    res.sendFile(__dirname + '/index1.html');
});

Give your html 'name' attribute.

To retrieve data on backend side you must just add name to input field

<!doctype html>
<html>
  <body>
<form id="frmTest" name="frmTest" action="http://localhost:3000/" method="post">
  <input type="text" id="mytext" name="mytext" value="sadfsad fsd fsad" />
  <input type="submit" id="mysubmit" />
</form>
  </body>
</html>
