This code snippet is an example of using getInitialProps to enable server-side rendering for a React application with Next.js. This code snippet is from the article originally published on RubyGarage’s blog: https://rubygarage.org/blog/how-to-integrate-ssr-for-react-app

getInitialProps.js

function Page({ stars }) {
  return <div>Next stars: {stars}</div>
}

Page.getInitialProps = async (ctx) => {
  const res = await fetch('https://api.github.com/repos/vercel/next.js')
  const json = await res.json()
  return { stars: json.stargazers_count }
}

export default Page
