You should use getStaticProps if :
* The data required to render the page is available at build time ahead of a user’s request
* The data comes from a headless CMS
* The page must be pre-rendered (for SEO) and be very fast — getStaticProps generates HTML and JSON files, both of which can be cached by a CDN for performance
* The data can be publicly cached (not user-specific). This condition can be bypassed in certain specific situation by using a Middleware to rewrite the path.
