Building a Full-Stack E-Commerce App with Next.js 15 and Prisma

In this post, I walk through the architecture and key decisions behind building a full-stack e-commerce application using Next.js 15, Prisma ORM, and PostgreSQL. ## Why Next.js 15? Next.js 15 brings significant improvements with the App Router, React Server Components, and improved caching strategies. For an e-commerce platform, server-side rendering is critical for SEO and performance. ## Database Design with Prisma Prisma provides a type-safe way to interact with your database. Here's a simplified schema for products and orders: ```prisma model Product { id String @id @default(cuid()) name String price Float category Category @relation(fields: [categoryId], references: [id]) categoryId String } model Order { id String @id @default(cuid()) items OrderItem[] status String @default("pending") createdAt DateTime @default(now()) } ``` ## Key Takeaways 1. **Server Components** reduce client-side JavaScript significantly 2. **Prisma** eliminates an entire class of SQL injection vulnerabilities 3. **TypeScript** catches bugs at compile time that would otherwise reach production ## Conclusion The combination of Next.js 15, Prisma, and PostgreSQL creates a robust foundation for modern web applications. The developer experience is exceptional, and the performance characteristics are excellent for production use.
