correct Terminal show message "server running on 8088"

But I done the biggest mistake. I was following the wrong project. I don't want to use third party APP. I want to make my Own APP that will turn on/off Led via web. i think it will good start.

I seen the forum post Ionic Framework use to create a simple app that turns on an LED. so I followed that project. I misunderstood by reading the top line of page
