I am following these commands to debug my app

Inside index.js

const debug = require('debug')('app:start')
debug('debugging the app... Yup!')

Inside Terminal

set DEBUG=app:start // inside terminal
nodemon index.js // inside terminal

Answer 1

Issue was very silly that I was running these two commands in different terminals that cause the problem

set DEBUG=app:start // inside terminal
nodemon index.js // inside terminal

be sure to run these commands in the same terminal. Hope this will save time for someone.
