Tell us about your experience working with Next.js. On which projects have you used it and what rendering methods did you employ for different content?

In Next.js projects, I used different rendering methods depending on the content type and SEO and performance requirements.

• Static Generation (SSG) — for pages with rarely changing content (e.g., blog, marketing pages). Used getStaticProps and getStaticPaths to generate pages at build time, ensuring fast loading and good SEO.

• Server-Side Rendering (SSR) — for dynamic content that depends on the user's request or updates frequently (e.g., personal account, pages with real-time data). Used getServerSideProps to generate the page on the server for each request.

• Client-Side Rendering (CSR) — for interactive parts of the application where data loads after the initial render (e.g., filters, dynamic lists). Used React hooks (useEffect) to load data on the client.

Example:

// Static generation
export async function getStaticProps() {
  const posts = await fetchPosts();
  return { props: { posts } };
}

// Server-side rendering
export async function getServerSideProps(context) {
  const user = await fetchUser(context.params.id);
  return { props: { user } };
}

This approach allows optimizing performance and SEO by choosing the appropriate rendering method for specific tasks.
