How do I handle errors in Next.js SSG?

In Next.js, you can handle errors in Static Site Generation (SSG) by using the getStaticProps function. You can return an error status or a fallback page.

Can you show me an example of that?

Sure! In your getStaticProps, you can catch errors and return a notFound property like this:

export async function getStaticProps() {
  try {
    const data = await fetchData();
    return { props: { data } };
  } catch (error) {
    return { notFound: true };
  }
}

What happens if I return notFound: true?

If you return notFound: true, Next.js will render the 404 page for that route, indicating that the content is not available.
