This blueprint outlines a high-performance, type-safe integration for Next.js 15 App Router with a distributed SQL backend using Drizzle ORM (v1.x) and the 'postgres.js' driver. It leverages React 19's stable Server Actions and Next.js 15's advanced caching primitives to ensure low-latency data fetching in edge-computing environments.
