When i type Any Name or anything string, i don’t get any response.

When you run npm init, it creates a package.json file. I’ve replaced that file later. I also updated the section to make it clear.
Check the firewall and SELinux config. Try disabling them both and see if the same happens. If you are using different version of CentOS, node.js or something else, that might be the problem too.

I followed all steps mentioned on blog, application is up ans running. when i send my username it showing no responce.
i remember during npm init you said “according to blog post we’ll replace this file later” what does this mean , you haven’t mentioned anything about the file in the post.
