Cached Fetch with Revalidation

interface Post {
  id: number;
  title: string;
  body: string;
}

export async function getPosts(): Promise<Post[]> {
  const res = await fetch('https://jsonplaceholder.typicode.com/posts', {
    next: { revalidate: 3600 }, // Cache for 1 hour
  });

  if (!res.ok) {

// In a Server Component:
// const posts = await getPosts();
