title: How to analyze create react app build size and reduce it?
body: <p>I have been following this guide: <a href="https://create-react-app.dev/docs/analyzing-the-bundle-size/" rel="noreferrer">https://create-react-app.dev/docs/analyzing-the-bundle-size/</a> and just about to run the <code>analyze</code> command to see how big my app is. is this the best way to check bundle/build size in React/JS?</p>
  
  <p>also is there a way to not include certain files from the prod build? like tests? Does CRA handle this automatically?</p>
