React vs React Server: What are the differences?
Developers describe React as "A JavaScript library for building user interfaces". Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project. On the other hand, React Server is detailed as "Blazing fast page load and seamless transitions". React-server is a framework designed to make universal (née isomorphic) React easier to write, providing standard answers for these questions and more. When you write your app for react-server, you concentrate on your React components, and react-server takes care of everything else that's needed to run and deploy real React server-rendered apps.
React and React Server can be categorized as "Javascript UI Libraries" tools.
React and React Server are both open source tools. React with 132K GitHub stars and 24.5K forks on GitHub appears to be more popular than React Server with 3.85K GitHub stars and 210 GitHub forks.
