What are the best practices for data fetching in Next.js?

The best practices for data fetching in Next.js include using getStaticProps for static generation, getServerSideProps for server-side rendering, and getStaticPaths for dynamic routes. This helps optimize performance and SEO.

Can you explain when to use getStaticProps vs getServerSideProps?

Certainly! Use getStaticProps when you want to pre-render a page at build time, which is great for static content. Use getServerSideProps when you need to fetch data on each request, ideal for dynamic content that changes frequently.

What about client-side data fetching?

For client-side data fetching, you can use React hooks like useEffect along with libraries like SWR or React Query. This is useful for data that doesn't need to be pre-rendered and can be fetched after the initial render.

Are there any performance considerations I should keep in mind?

Yes, consider the size of the data being fetched, the number of requests, and caching strategies. Using incremental static regeneration can also help improve performance by allowing you to update static pages without a full rebuild.
