Technical Blueprint for integrating Next.js 15 (React 19) with a PostgreSQL database using Drizzle ORM and Server Actions. This architecture leverages the App Router for end-to-end type safety and optimal performance in serverless environments using a singleton pattern for the database client to prevent connection exhaustion.
