Architecture

Backend

// API route for product fetching
export async function GET(request: Request) {
  const { searchParams } = new URL(request.url);
  const page = searchParams.get("page") || "1";
  const limit = 20;

  const products = await db.product.findMany({
    skip: (parseInt(page) - 1) * limit,
    take: limit,
  });

  return Response.json(products);
}

Frontend

export async function ProductCatalog() {
  const products = await fetchProducts();

  return (
    <div className="grid grid-cols-1 md:grid-cols-3 gap-6">
      {products.map((product) => (
        <ProductCard key={product.id} product={product} />
      ))}
    </div>
  );
