To structure a NestJS backend with the repository pattern, organize code under modules/<feature>/ with strict separation of concerns between controllers, services, and custom TypeORM repositories. This ensures predictable, scalable backend development with explicit typing and snake_case database columns.

The best way to standardize a NestJS module layout is to enforce a uniform directory structure under apps/api/src/modules/<feature>/ with clearly separated concerns. This includes consistent entity modeling, explicit DTO usage, and explicit naming conventions across all generated files.

Yes, this NestJS backend standardization approach supports role-based access control by providing a dual-authentication framework. It includes platform versus tenant guards and defines JWT payload shapes to manage access securely across different modules.

To enforce separation of concerns in NestJS, apply a strict module pattern that isolates controllers for routing, services for business logic, and repositories for database operations. This architecture prevents logic overlap and maintains scalable code.

Yes, you can use snake_case database columns with TypeORM entities in a NestJS application. The standardization enforces consistent entity modeling with explicit typing and snake_case naming for database columns to ensure predictable data mapping.
