how to organize files (react,php)

Hello, how to organize a React folder with laravel? i didn’t see any article in codecanyon, i found an article for nodejs but not for react, in main files should i include the build folder of react? or should i include the original react application? and should i also explain to the buyer how to download (npm, create-react-app) and teach him how to build it?
if anyone has already publish React items , please share your
