getserversideprops vs getstaticprops

use getServersideProps when data will change after time like wordpress post
which will be changing when new we add new post.
Use getStaticProps when it is static content using it make it cache in.nextjs
so it will load fast.
//Note if you use getStaticProps in dynamic content section then content which 
//is added after deployment will not shown cause it also shown content from cache.

getserversideprops

export async function getStaticPaths() {
  const res = await fetch(`${baseUrl}/wp-json/wp/v2/posts`)
  const posts = await res.json()
  //paths is array of objects which is contains one params property with id or slug
  const paths = posts.map(({ slug }) => ({ params: { slug: `${slug}` } }))

  return {
    paths,
    //fallback true mean there is no slug in build time then it will not shown 404 error 
    // and fetch data from server and show it
    fallback: true,
  }
}
