Sample node.js doing form handling and processing - in Node.js

Question

I need a pointer or sample tutorial or some examples to form handling in Node.js. I have a form.html which has 3 buttons "Forward", "Backward", "Stop" and they will have to call a process get and appropriately send messages to the backend component to take appropriate action. My sample node.js that comes when I create the application is good, but it does not have form processing, so a link to some worked examples would help a lot.

You can use the express framework to process the form.

<form action="/processForm" method="POST">
  What's your name?: <input type="text" name="yourname"><br>
  <input type="submit" value="Forward">
</form>

node backend:

app.post('/processForm',function(req,res){
  var yourname=req.body.yourname;
  res.end("Hello " + yourname);
});
