rari is a React Server Components framework built on a Rust runtime, offering significant performance improvements over Next.js. It features a zero-config setup, true server-side rendering, and automatic loading states, making it easy to build efficient web applications.

The article explores the concept of using JSX over the wire, which allows developers to send serialized JSX components from the server to the client, enhancing performance and interactivity in web applications. It discusses the implications of this approach for server-rendered applications and how it can streamline rendering processes while maintaining a React-like experience. The author also examines potential challenges and considerations when implementing this technique.
