I have a project in Astro that has sanity installed and needs pagination and dynamic routes.

Sure, I can guide you on how to implement pagination and dynamic routes in Astro using the information provided in the extracts.
Dynamic Routes
Astro uses file-based routing to generate your build URLs based on the file layout of your project src/pages/ directory. An Astro page file can specify dynamic route parameters in its filename to generate multiple, matching pages. For example, src/pages/authors/[author].astro generates a bio page for every author on your blog. author becomes a parameter that you can access from inside the page.
For your blog posts, you can create a file like src/pages/posts/[slug].astro to generate a page for each post. You will need to create a getStaticPaths() function in your page frontmatter script and tell Astro exactly what paths to build for that route. Here's an example:
---
// src/pages/posts/[slug].astro
// Tell Astro what pages to build for your route "/pages/:slug"
export async function getStaticPaths() {
return [
// Generates: /pages/hello-world
{ params: { slug: "hello-world" } },
// Generates: /pages/my-first-blog-post
{ params: { slug: "my-first-blog-post" } },
// Generates: /pages/astro-ftw
{ params: { slug: "astro-ftw" } },
// ...
]
}

Pagination
Astro supports built-in pagination for large collections of data that need to be split into multiple pages. Astro will generate common pagination properties, including previous/next page URLs, total number of pages, and more. Paginated route names should use the same [bracket] syntax as a standard dynamic route. For instance, the file name /astronauts/[page].astro will generate routes for /astronauts/1, /astronauts/2, etc, where [page] is the generated page number.
You can use the paginate() function to generate these pages for an array of values. Here's an example:
---export async function getStaticPaths({ paginate }) {
const astronautPages = [
{ astronaut: 'Neil Armstrong', },
{ astronaut: 'Buzz Aldrin', },
{ astronaut: 'Sally Ride', },
{ astronaut: 'John Glenn', }
];
// Generate pages from our array of astronauts, with 2 to a page
return paginate(astronautPages, { pageSize: 2 });
}
// All paginated data is passed on the "page" prop
const { page } = Astro.props;
---
<!--Display the current page number. Astro.params.page can also be used!-->
<h1>Page {page.currentPage}</h1>
<ul>
<!--List the array of astronaut info-->
{page.data.map(({ astronaut }) => <li>{astronaut}</li>)}
</ul>

Please replace the astronautPages array with your blog posts data from Sanity. You can adjust the pageSize to control the number of items shown per page.
