What problem does it solve?

Establishes a repeatable, architecture-first approach for building Design Token Manager APIs with Node.js/Express, Prisma, and PostgreSQL, ensuring consistent patterns across routes, controllers, and data access.

Core Features & Use Cases

• Three-Layer Architecture (Routes → Controllers → DAL → Prisma → PostgreSQL) to separate concerns.
• Enforces multi-tenant data isolation on every query with tenantContext-aware DAL.
• Standardized patterns for authentication, error handling, validation, and testing.
• Guidelines for Prisma usage, transactions, and performance considerations.

Quick Start

Apply these standards when scaffolding new API routes or refactoring existing ones to ensure multi-tenant isolation, consistent error handling, and aligned DAL usage.
