FAQ

🧐 Where can I find an example of how to use the package?
📣 You can find a live example on this site - react-roulette-pro.ivanadmaers.com and in the example folder.

🧐 How can I customize the roulette?
📣 First, you can pass a prizeItemRenderFunction to render prize items by yourself. Second, you can use a specific design plugin. Third, you can pass your specific classes via classes prop. Avoid to rewrite the roulette and its plugins default styles.

🧐 Is it possible to use this package with SSR?
📣 Of course! This package does not use a global object window. You can use this package without any problems. And I'd like to recommend you to use dynamic in NextJS to decrease your bundle size and render it only on client side.

import dynamic from 'next/dynamic';

const RoulettePro = dynamic(() => import('react-roulette-pro'), {
  ssr: false,
});

🧐 What version of React does this package support?
📣 Your versions should be:

• react >=17.0.0
• react-dom >=17.0.0
• NodeJS >=10

🧐 Are pull requests welcome?
📣 Any ideas to improve this package are very welcome!
