Implementation Highlights

Server Components & Actions

// app/products/page.tsx
export default async function ProductsPage() {
  const products = await prisma.product.findMany({
    include: { category: true, images: true }
  });

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

// Server Action for adding to cart
'use server'
export async function addToCart(productId: string, quantity: number) {
  const session = await getServerSession(authOptions);
  
  if (!session) {
    throw new Error('Unauthorized');
  }

  await prisma.cartItem.create({
    data: {
      userId: session.user.id,
      productId,
      quantity
    }
  });
  
  revalidatePath('/cart');
}

Stripe Integration

// app/api/checkout/route.ts
import { stripe } from '@/lib/stripe';

export async function POST(request: Request) {
  const { items } = await request.json();
  
  const session = await stripe.checkout.sessions.create({
    payment_method_types: ['card'],
    line_items: items.map(item => ({
      price_data: {
        currency: 'usd',
        product_data: {
          name: item.name,
          images: [item.image]
        },
        unit_amount: item.price * 100
      },
      quantity: item.quantity
    })),
    mode: 'payment',
    success_url: `${process.env.NEXT_PUBLIC_URL}/success`,
    cancel_url: `${process.env.NEXT_PUBLIC_URL}/cart`
  });

  return Response.json({ url: session.url });
}
