nestjs-best-practices

Structure scalable NestJS modules by implementing modular feature modules with proper sharing and event-driven patterns. This architecture guidance improves modularity and dependency injection to deliver maintainable, scalable server-side applications.

The best way to apply dependency injection in NestJS is using constructor injection with interfaces and tokens. Combine this with provided testing utilities to enforce proper patterns, ensuring your codebase remains testable and maintainable.

Yes, you can audit an existing NestJS codebase to identify anti-patterns. It evaluates your project to apply recommended patterns for modules, guards, pipes, and interceptors to refactor for better maintainability and scalability.

Yes, this NestJS guidance covers security and performance best practices. It enforces patterns for proper JWT usage, input validation, guards, caching, and database best practices to improve your application's overall security posture.

Review NestJS architecture across REST, GraphQL, and TypeORM projects by applying enforced patterns for migrations and interceptors. This skill supports architecture reviews and refactoring to deliver maintainable, scalable code across these integrations.

A limitation when refactoring NestJS dependency injection is that it requires strict adherence to constructor injection and interface tokens. Failing to follow these enforced patterns during architecture reviews may prevent achieving the desired scalable structure.
