3  const { searchParams } = new URL(request.url);
4  const page = searchParams.get("page") || "1";
5  const limit = 20;
6
7  const products = await db.product.findMany({
8    skip: (parseInt(page) - 1) * limit,
9    take: limit,
10  });
11
12  return Response.json(products);
13}

Frontend

React components with server-side rendering:

React TSX
11 linesCopy
1export async function ProductCatalog() {
2  const products = await fetchProducts();
3
4  return (
5    <div className="grid grid-cols-1 md:grid-cols-3 gap-6">
6      {products.map((product) => (
7        <ProductCard key={product.id} product={product} />
