This tutorial guides developers through constructing a full-stack blog application using Next.js, Clerk authentication, and a PostgreSQL database via Drizzle ORM deployed on Vercel with a Neon database. The guide progressively adds tRPC for type-safe API endpoints, implementing both public and protected procedures that restrict certain operations to authenticated users only. The approach demonstrates modern best practices including Tanstack Query and Zod validation integrated with Clerk authentication context.
