Server-Side Rendering (SSR)
Next.js enables server-side rendering out of the box, allowing you to pre-render pages on the server and send fully formatted HTML to the client. This approach improves SEO and initial load times.
Client-Side Rendering (CSR)
For dynamic content that doesn't require SEO optimization, Next.js supports client-side rendering. This can be useful for interactive features that require real-time updates.
Static Site Generation (SSG)
Next.js also offers static site generation, where pages are pre-built at build time. This approach is great for content-heavy websites with relatively stable data.
