How to get the server s port

0 votes

You often see example hello world code for Node that creates an Http Server, starts listening on a port, then followed by something along the lines of:

console.log('Server is listening on port 8000');

But ideally you'd want this instead:

console.log('Server is listening on port ' + server.port);

How do I retrieve the port the server is currently listening on without storing the number in a variable prior to calling server.listen()?

Hello @kartik,

I use this way Express 4:

app.listen(1337, function(){
  console.log('Express listening on port', this.address().port);
});

By using this I don't need to use a separate variable for the listener/server.

Hope this helps!!
ThanK you!!
