title: unpacked size of my node module suddenly increased much bigger with no much change
body: <p>I created this node package</p>
  <p>When it was the version of 1.7.3, Its unpacked size was only 618KB</p>
  <p>But after updating to the version of 2.0.0 with just a little file change, its size became 4.35 MB</p>
  <p>The super weird thing is the fact that I rather reduced file size after the 1.7.3 version by removing a third-party module that I had imported and a few js and CSS files from this project but still, it's 4.13MB</p>
  <p>1.I don't think the unpacked size is related to the actual size of the node module. is that right?</p>
  <ol start="2">
  <li><p>If I'm correct what exactly is unpacked size and is there a way to reduce the size?</p>
  </li>
  <li><p>If I'm wrong, what factors might have increased the size? and How could I reduce the unpacked size?</p>
  </li>
  </ol>
  <h2>Note</h2>
  <p>I started this project with <code>npx create-react-library</code> command.
  created by <a href="https://www.npmjs.com/package/create-react-library" rel="nofollow noreferrer">https://www.npmjs.com/package/create-react-library</a>
  Whenever I was trying to publish, what I did was just one command</p>
  <pre><code>npm publish
  </code></pre>
  <p>this command did all work for me to publish.</p>
  <p>This was my first time to create a node package. So please understand me if it turns out to be a very silly mistake.</p>
