@MorganCheng @nagkumar This is not correct. Many companies are doing SSR with React (in production) and they are doing just fine. Hashnode itself heavily utilizes server side rendering capability of React and we have not see any bottleneck so far. Also, at Facebook they have use cases where React is being used to render components on the server.
@sandeep As the link states "there are very few places where we're using React to render on the serve". I know that there are quite a few companies put SSR of React into production, but it doesn't change the history. twitter.com/cpojer/status/711729444323332096
Yahoo has invented Fluxible to support better SSR, it proves that React has poor performance in server side. It takes a lot of efforts to optimize it, but the gains are not much.
