title: How to add my file to an existing zip-folder using node-js in lambda?
body: <p>I have a zip folder downloaded from s3 bucket. Now I have a json file in my code, and I want to add my JSON file to an existing zip file using node js code.</p>
  <p>Is there any pre existing module for doing this in node js?</p>
  <p>I tried <a href="https://www.npmjs.com/package/easy-zip" rel="nofollow noreferrer">easy-zip</a>, but I was not able to add the file to an existing zip-folder.</p>
  <p>Any idea on this?</p>
