title: how to add input values to npm modules
body: <p>I'm creating an API module but I tested this script and <code>configl</code> is started giving an error. How do I fix this problem?</p>
  
  <pre><code>const index = require("./index");
  
  exports.shorten(configl) = function() {
      const shortenlink = config
    };
  
  exports.postlink = shortenlink;
  
  module.exports = shorten;
  </code></pre>
