title: How to define the property file in node js?
body: <p>I have found an article about properties file reader in node js here:
  <a href="https://www.npmjs.com/package/properties-reader" rel="noreferrer">https://www.npmjs.com/package/properties-reader</a></p>
  
  <p>There is a module as 'properties-reader'. But, I'm unable to understand how to define the property file. Should it be a json?</p>
