Client-Side Rendering (CSR)

typescript
function Users() {
  const { data } = useQuery('users', fetchUsers);
  return <UserList users={data} />;
}

Server-Side Rendering (SSR)

typescript
// Next.js
export async function getServerSideProps() {
  const users = await fetchUsers();
  return { props: { users } };
}

export default function Page({ users }) {
  return <UserList users={users} />;
}

Static Site Generation (SSG)

typescript
// Next.js
export async function getStaticProps() {
  const users = await fetchUsers();
  return { props: { users }, revalidate: 60 };
}

Resources

• SSR: SEO, real-time data
