Localhost doesn't launch when triggered by nodeJS

Question

I have a Wamp server on windows & I have installed visual studio code for running nodejs programs.
As first step m trying to run a sample program which will display an HTML page.
But the issue is, localhost refuses to connect.

As checked, currently the port set in httpd.conf is set to 80 & if launch directly localhost does open on this port.
But when I try to do d same through nodejs it just doesn't launch it.

Can anyone help regarding this issue.
Thanks in advance for your support!
