The term serverside rendering refers to a web application development technique where web pages are generated on the server before being sent to the client. This contrasts with client-side rendering, where content is rendered in the browser. Server-side rendering enhances performance, as it delivers fully rendered pages faster and improves SEO by making web content more accessible to search engines. It is particularly beneficial for applications with complex data requirements or high traffic. By optimizing the initial load time and user experience, server-side rendering plays a critical role in modern web development.
