Kent C Dodds - And Now You Understand React Server Components, React Summit 2024

Learn how React Server Components improve performance in client-side rendered applications with smoother navigation, reduced data transfer, and faster UI updates through rendering React components on the server and streaming HTML to the client.

Key takeaways
  • React Server Components (RSC) is a new concept that allows rendering React components on the server without a full page refresh.
  • RSC is not a new technology, but rather a new way of thinking about how to handle client-side rendering.
  • The main advantage of RSC is that it allows for smoother navigation and reduces the amount of data sent over the network.
  • RSC is achieved by creating a special kind of React component that can be rendered on the server, and then sending the resulting HTML to the client.
  • The client can then update the UI without having to send a full page refresh.
  • The speaker uses the term “use client” to describe the process of rendering React components on the server.
  • The speaker suggests that RSC is not a solution for every problem, but it can be a powerful tool for improving the performance of client-side rendered applications.
  • The speaker provides a simple example of how to use RSC in a React application.
  • The speaker mentions that RSC is not a replacement for client-side rendering, but rather a way to improve the performance of client-side rendered applications.
  • The speaker suggests that RSC is a promising new technology that can help improve the performance of React applications.
