node.js: Updating an app without the need to stop and run again

Question

I've started playing with node.js and express.js and wrote an hello-world app following the docs:

app.get('/hello', function(req, res){
  res.send('Hello World');
});

If I change the code and refresh the browser - nothing happens.
I have to stop the server and run it again.

Is there a solution for that?

Yes, you do have to stop it and start it again.

There are apps that do this automatically for you. Check out nodemon for example: https://github.com/remy/nodemon
