Summary of Serverside Rendering in React - The Basics | Contabo Blog

Server-side rendering (SSR) is a technique used in web development, particularly for React applications. It involves generating the initial HTML content of a web page on the server before sending it to the client's browser. This approach offers benefits such as improved initial load time, enhanced SEO, better performance on low-powered devices, and an improved user experience.

The process of SSR includes handling a user request on the server, processing data, rendering HTML, and then delivering this fully rendered HTML to the client's browser for display. This method provides a faster initial loading experience compared to client-side rendering (CSR), as the server sends pre-rendered HTML.

When setting up an SSR React application, you need tools like Node.js, Express, React, ReactDOM, Babel, etc. Creating a simple SSR React app involves creating a project, installing dependencies, setting up Babel configuration, and modifying the React app to be exportable.

Implementing SSR comes with its own challenges and considerations, including performance implications, SEO benefits, potential drawbacks, and best practices for optimization. By understanding these factors, developers can make informed decisions and build fast, SEO-friendly, and user-centric React applications using SSR.
