const categories = await client.getCategories();

// Get posts from the "technology" category
const techPosts = await client.getCategoryPosts('technology', 1, 10);

// Implement pagination for a category
let currentPage = 1;
const postsPerPage = 10;

async function loadCategoryPage(category: string, page: number) {
  const posts = await client.getCategoryPosts(category, page, postsPerPage);
  
  if (posts.length === 0) {
    console.log('No more posts in this category');
    return;
  }
  
  // Render posts
  posts.forEach(post => {
    console.log(`- ${post.headline} (${post.readingTime} min read)`);
  });
}
