nextjs-data-fetching

Next.js route handlers support data fetching and caching through native fetch extensions and route exports. Applying correct fetch options and revalidation strategies ensures data consistency and high performance for API endpoints.

To revalidate cached data in SSG and ISR, apply specific fetch options and route exports to enforce revalidation strategies. This keeps static and incrementally generated pages fresh without rebuilding the entire application.

Use unstable_cache when you need to cache data outside of the standard fetch extension lifecycle. Native fetch extensions handle standard route-level caching, while unstable_cache provides flexibility for third-party APIs or database queries.

Yes, the data fetching approach fully supports React Server Components (RSC). It applies appropriate rendering modes and fetch options to ensure RSC routes correctly fetch, cache, and revalidate data for optimal server-side rendering.

Use generateStaticParams to define dynamic route segments at build time. By combining it with correct fetch options and caching strategies, you can statically generate pages with pre-fetched, cached data for fast loading.

Incorrect fetch caching usually occurs when fetch options lack explicit caching or revalidation configurations. Enforcing correct route exports and revalidation strategies ensures that Next.js routes fetch, cache, and revalidate data properly.
