Hi I just stumbled upon your code from your medium article. Mind if I ask for details of the copyPublicFolder() func? Is it just copying files in the paths.appBuild folder?

Hey @p10petr, Its been a while since that medium article but the copyPublicFolder was a fn in the build.js file of create-react-app. This is the current implementation that they have, found here src.

function copyPublicFolder() {
  fs.copySync(paths.appPublic, paths.appBuild, {
    dereference: true,
    filter: file => file !== paths.appHtml,
  });
}

Cheers! Much appreciated :)
