I'll help you with implementing pagination in Astro for your WordPress REST API data.
There are a few issues with your current implementation. The getStaticPaths function in Astro needs to return an array of objects with params and optionally props, and you're trying to use the paginate() helper function but not implementing it correctly.
Here's how you can properly implement pagination for WordPress REST API posts in Astro:
---
// src/pages/blog/[page].astro
export async function getStaticPaths({ paginate }) {
const postPerPage = 10; // Set your desired posts per page
const apiUrl = '<https://your-wordpress-site.com/wp-json/wp/v2';>
// First, we need to know how many total posts there are
const countResponse = await fetch(`${apiUrl}/posts?per_page=1`);
const totalPosts = parseInt(countResponse.headers.get('X-WP-Total') || '0');
const totalPages = Math.ceil(totalPosts / postPerPage);
// Function to fetch posts for a specific page
const getAllPosts = async (page) => {
try {
const response = await fetch(
`${apiUrl}/posts?per_page=${postPerPage}&page=${page}&_fields=slug,title,date,acf`
);
return await response.json();
} catch (error) {
console.error('Failed to fetch blogs:', error);
throw error;
}
};
// Fetch first page to pass to paginate()
const firstPagePosts = await getAllPosts(1);
// Use paginate() to generate pages
return paginate(firstPagePosts, {
pageSize: postPerPage,
props: { totalPages }
});
}
// The page data is passed automatically by paginate()
const { page, totalPages } = Astro.props;

<h1>Blog Posts</h1>
<ul>
{page.data.map((post) => (
<li>
<a href={`/blog/${post.slug}`} set:html={post.title.rendered} />
</li>
))}
</ul><!-- Pagination component -->
<nav>
{page.url.prev ? <a href={page.url.prev}>Previous</a> : null}
{page.url.next ? <a href={page.url.next}>Next</a> : null}
<p>Page {page.currentPage} of {page.lastPage}</p>
</nav>
This implementation uses Astro's built-in pagination features as described in the [Astro documentation on pagination](<https://docs.astro.build/en/guides/routing/#pagination>). The `paginate()` function automatically generates the necessary pages and provides useful pagination metadata through the `page` prop.
The `page` prop includes:
- `page.data`: The array of posts for the current page
- `page.currentPage`: The current page number
- `page.lastPage`: The total number of pages
- `page.url.prev`: URL to the previous page (if it exists)
- `page.url.next`: URL to the next page (if it exists)
- And other useful properties like `page.url.first` and `page.url.last` for navigation
Note that this approach works best for static site generation. If you need server-side rendering for your pagination, you would need to adjust this approach accordingly.
