Implementing cursor-based pagination in Next.js API Route with Prisma and leveraging the power of useSWRInfinite

I am working on implementing cursor-based pagination for a table of posts using Next.js API Route, Prisma, and useSWRInfinite.

Currently, I am fetching the ten most recent posts with Prisma in a Next.js API Route and displaying them using useSWR, sorted by createdAt in descending order.

The goal is to utilize the useSWRInfinite hook to enable loading an additional ten posts through cursor-based pagination upon clicking a 'Load More' button. This will also include displaying the total count of posts.

Based on the documentation from SWR and Prisma, it appears that modifications are needed in the API route to handle cursors and logic adjustments in the useSWRInfinite hook to manage cursor data transfer.

Below is the code snippet:

API Route

export async function getPost(
  req: NextApiRequest,
  res: NextApiResponse,
  session: Session
): Promise<void | NextApiResponse<AllPosts | (WithSitePost | null)>> {
  // Code implementation here
}

Posts Page

const router = useRouter();
// Code implementation here

Explore the informative guide on Prisma's cursor-based pagination feature: https://www.prisma.io/docs/concepts/components/prisma-client/pagination#cursor-based-pagination

In your findMany query, you have the option to include a skip property to skip X elements and/or a cursor property to specify where Prisma should start searching from. Remember to use both: set skip: 1 to move past the cursor and provide the correct value for the cursor property to indicate the starting point for the search.
