Building a Production-Ready Next.js App

When building a production application with Next.js, there are several key considerations that separate a demo from a real product.

#Architecture First

Start with a clear separation between public and admin routes. Use Server Components by default and only add client interactivity where needed.

// app/page.tsx — Server Component by default
export default async function Page() {
  const data = await fetchData()
  return <HomePage data={data} />
}

#Database & Auth

Choose PostgreSQL with Prisma for type-safe database access. Auth.js v5 integrates seamlessly with the App Router.

The key is defense in depth: protect routes at the proxy layer AND in every API handler.

#Conclusion

Production readiness is about thoughtful architecture, not over-engineering.
