What are the performance differences between SSR and CSR in JavaScript frameworks?

What are the performance differences between SSR and CSR in JavaScript frameworks?

SSR (Server-Side Rendering) generates HTML on the server, which can lead to faster initial load times. CSR (Client-Side Rendering) generates HTML in the browser, which may result in slower initial loads but can be more interactive.

Which one is better for SEO?

SSR is generally better for SEO because search engines can crawl the fully rendered HTML. CSR can be less effective unless properly configured with prerendering or server-side support.

What about user experience?

CSR can provide a smoother user experience with faster interactions after the initial load, while SSR may feel slower initially but can be more responsive for first-time visitors.

Are there any frameworks that excel in both?

Yes, frameworks like Next.js and Nuxt.js offer hybrid approaches, allowing developers to choose between SSR and CSR based on the needs of their application.
