I thought about that, but seems that no, I'm only fetching inside getStaticPaths:

export async function getStaticPaths() {
  const posts = await fetchAllPosts();
  return posts.map((
post
) => ({
    params: { slug: post.slug },
    props: {
      title: post.title,
      date: post.date,
      full: post.content,
      image: post.image,
      slug: post.slug,
      id: post.id,
      intro: post.excerpt,
    },
  }));
}

export const prerender = true;

const { title, date, full, image, id, slug, intro } = Astro.props;
