Monorepo Full-Stack Stack (Turborepo, Next.js, NestJS, Prisma, PostgreSQL) overview

A TypeScript-first monorepo architecture for full-stack web applications where frontend, backend, and shared libraries live in a single repository with unified tooling. Turborepo provides incremental builds, remote caching, and task orchestration across packages. Next.js serves the frontend with SSR, ISR, and API routes. NestJS provides a structured backend framework with dependency injection, guards, and decorators. Prisma handles database access with a type-safe ORM, auto-generated client, and declarative schema migrations. PostgreSQL is the production database. TypeScript spans every package, enabling shared types and validation schemas (via Zod) between frontend and backend without code duplication. This stack suits product-focused teams of 5-20 engineers who want maximal code sharing and a single CI pipeline. The tradeoff is monorepo complexity — build caching, dependency hoisting, and CI performance require ongoing attention as the repo grows.
