Understanding Next.js Static Exports

Next.js provides a powerful way to generate fully static websites. By setting output: 'export' in your next.config.js (or enforcing it with export const dynamic = 'error'), you guarantee that all pages are pre-rendered at build time.

Why Static Exports?

1. Performance: Static HTML files load instantly.
2. Security: No database or server logic is exposed at runtime.
3. Hosting: Can be deployed anywhere (Cloudflare Pages, GitHub Pages, Vercel, S3).

Example Configuration

Here is how you might configure a statically exported page:

// app/page.tsx
export const dynamic = 'error';

export default function Home() {
  return <h1>Hello, Static World!</h1>;
}

Notice the dynamic = 'error' setting. If any component in the tree attempts to read request-time data (like search params or cookies), the build will fail immediately instead of falling back to dynamic rendering. This is crucial for maintaining performance guarantees.
