What are the differences between Next.js SSR and client-side rendering?

What are the differences between Next.js SSR and client-side rendering?

Next.js SSR (Server-Side Rendering) generates HTML on the server for each request, while client-side rendering (CSR) generates HTML in the browser after the initial load. SSR can improve SEO and load times for users, while CSR can provide a more dynamic user experience.

Which one is better for SEO?

SSR is generally better for SEO because search engines can crawl the fully rendered HTML. CSR may require additional setup for SEO optimization.

What are the performance implications of using SSR?

SSR can lead to faster initial page loads since the server sends a fully rendered page. However, it may increase server load and response times if not optimized properly.

Can I mix SSR and CSR in a Next.js application?

Yes, Next.js allows you to mix SSR and CSR. You can use SSR for critical pages and CSR for less important ones, providing flexibility in your application.

What are some use cases for each rendering method?

SSR is great for content-heavy sites like blogs or e-commerce, while CSR is ideal for single-page applications or interactive dashboards.
