← All Next.js questions
Re-explain
getServerSideProps fetches data on each request at runtime:
export async function getServerSideProps(context) {
const { req, res, params, query } = context;
const data = await fetch(`https://api.example.com/user/${params.id}`);
const user = await data.json();
return {
props: {
user,
},
};
}
Use when: Data changes frequently, requires authentication, or needs request-specific information.
