server.listen(3000, function(){
    console.log("Server started at port: 3000");
});

The server.js file can be run using node server.js command .The following screenshot shows the terminal with server.js in execution.

The output of this demo will look like following screenshot:-

Now we can configure PM2 in Windows using some DOS command. The following screenshot shows NodeJS command prompt CLI opened in Administrative mode with DOS command executed:-
