For example localhost:3000/categories/1 exists, but localhost:3000/categories/2 does not exists so to return 404 that page does not exists
pages

----categories
-----------index.js
-----------[id].js
For example if an ID does not exist in the database, how to pre-check if does not exists return 404 page
CodePudding user response:
I would fetch for data on your front-end, if data exists display the page if not redirect to your 404 error page.
CodePudding user response:
At the getServerSideProps check for the data, and if data does not exists:
if (!categories) {
return {
notFound: true,
};
}
This will return to the 404 file.
