What is the fastest way to serve static pages in a Next.js application?
Quick Answer: The fastest way to serve static pages in a Next.js application is to use Static Site Generation (SSG) or, for fully fixed content, pre-rendered static export so pages are built once and served from the CDN edge with no server-side computation on request. In practice, this means minimizing runtime rendering, avoiding unnecessary client-side data fetching, and letting Next.js cache HTML and assets aggressively through its build pipeline and global delivery network.
Detailed Explanation
For maximum performance, Next.js should generate pages ahead of time rather than assembling them on each request. Static Generation produces HTML at build time and allows those pages to be distributed through a CDN, which typically yields the lowest latency, highest cache hit rates, and the best scalability under load. If content is completely immutable, a static export can remove server execution entirely; if content changes periodically, SSG combined with Incremental Static Regeneration can preserve near-static speed while refreshing pages in the background. The key is to shift work left into the build process, keep page data dependencies deterministic, and reduce hydration and bundle overhead so the browser receives a minimal, cache-friendly response.
Key Technical Drivers
- Use `getStaticProps` and `getStaticPaths` for pages whose content can be pre-rendered at build time, so requests are served as cached HTML instead of invoking server logic.
- Serve assets and prerendered pages through a CDN or edge cache, and keep page markup deterministic to maximize cacheability and reduce TTFB.
- If content must update, use Incremental Static Regeneration (`revalidate`) to retain static performance while refreshing pages asynchronously without blocking the user request.
