Next.js offers several rendering methods that cater to different use cases, including Client-Side Rendering (CSR), Server-Side Rendering (SSR), Static Site Generation (SSG), and Incremental Static Regeneration (ISR). This discussion focuses primarily on SSG and SSR, as they are the most commonly used and debated methods. SSG pre-renders pages during build time, distributing static files via a CDN for faster loading times, while SSR generates pages on the server at request time, providing the latest data with each request. SSG excels in performance and SEO due to its faster server response times, but it requires a full rebuild for content updates, which ISR can help mitigate by allowing partial rebuilds. SSR, on the other hand, is advantageous for serving dynamic content and accessing request-specific data but can be resource-intensive and slower due to generating pages per request. Both methods offer significant SEO benefits, though SSG generally provides faster loading times, and the choice between them depends on specific application requirements such as data freshness, performance needs, and content update frequency.
