Pagination is an essential feature in web applications that handle large datasets. It improves the user experience by dividing content into manageable chunks, preventing long loading times, and offering easy navigation. In a Shopify Remix app, implementing pagination can be done efficiently using Prisma with the skip and take methods. This blog will guide you through the process of setting up pagination in your Shopify Remix app using Prisma.

Prisma is an open-source ORM (Object-Relational Mapping) tool that simplifies database access and management in Node.js and TypeScript applications. It provides a type-safe query builder that allows developers to interact with databases using an intuitive API.
In Prisma, the skip and take methods are used to implement pagination:
By combining these two methods, you can efficiently retrieve a specific subset of data from your database.
The loader function in Remix is used to fetch data before rendering a page. Here’s how to set it up for pagination:
// app.products.jsx export async function loader({ request }) { const { session, admin } = await authenticate.admin(request); const url = new URL(request.url); const searchParam = url.searchParams; const skip = Number(searchParam.get("skip")) || 0; const take = Number(searchParam.get("take")) || 5; // Fetch total count of products const totalCount = await db.product.count({ where: { shop: session.shop }, }); // Fetch paginated products const products = await db.product.findMany({ skip: skip, take: take, where: { shop: session.shop }, orderBy: { id: "desc" }, }); return json({ products, totalCount, skip, take }); }
Explanation:
In the React component, handle the pagination logic and render the paginated data using Shopify Polaris’s IndexTable component.
function Products() { const { products, totalCount, skip, take, searchQuery } = useLoaderData(); const navigate = useNavigate(); const totalPages = Math.ceil(totalCount / take); const currentPage = Math.floor(skip / take) + 1; const [searchValue, setSearchValue] = useState(searchQuery || ""); const formattedQuery = searchValue.replace(/\s+/g, '-'); const pagination = { previous: { disabled: currentPage <= 1, link: currentPage > 1 ? `/app/products/?query=${formattedQuery}&skip=${Math.max(skip - take, 0)}&take=${take}` : null, }, next: { disabled: currentPage >= totalPages, link: currentPage < totalPages ? `/app/products/?query=${formattedQuery}&skip=${skip + take}&take=${take}` : null, }, }; return ( <Page title="Product Management"> <IndexTable resourceName={{ singular: "product", plural: "products" }} itemCount={products.length} headings={[ { title: "id" }, { title: "Title" }, ]} pagination={{ hasPrevious: currentPage > 1, onPrevious: () => { if (pagination.previous.link) { navigate(pagination.previous.link); } }, hasNext: currentPage < totalPages, onNext: () => { if (pagination.next.link) { navigate(pagination.next.link); } }, }} > {products.map(({ id, productImage }, index) => ( <IndexTable.Row id={id} key={id}> <IndexTable.Cell>{id}</IndexTable.Cell> <IndexTable.Cell>{productTitle}</IndexTable.Cell> </IndexTable.Row> ))} </IndexTable> </Page> ); }
Implementing pagination with Prisma’s skip and take parameters in a Shopify Remix app helps manage large datasets efficiently. By fetching only a subset of data and providing intuitive navigation controls, you improve both performance and user experience.
