Scalable NestJS applications should use feature-based modules with single-responsibility services and proper module sharing to enforce architecture best practices. This approach standardizes module design and maintains code consistency across REST and microservices.

The best way to standardize NestJS dependency injection is using constructor injection alongside proper interfaces and injection tokens. This enforces consistent architectural patterns across teams during module design and code refactoring.

To apply NestJS security and performance best practices, implement vetted guidelines using guards, pipes, and lifecycle hooks. This ensures robust API design and application protection during development and code reviews.

Yes, this architectural approach works for both REST APIs and microservices in NestJS. It provides consistent guidance for module design, refactors, and reviews across different communication paradigms to maintain scalable applications.

You should use feature-based modules in NestJS when establishing consistent patterns across teams or refactoring existing code. This pattern solves the challenge of building maintainable applications by enforcing single-responsibility services and proper module sharing.
