What problem does it solve?

NestJS architecture and best-practices guidance to help teams build scalable, maintainable server-side apps with NestJS.

Core Features & Use Cases

Architecture guidance: modular feature modules, proper module sharing, and event-driven patterns.
Dependency Injection and testing: constructor injection, interfaces/tokens, and testing utilities.
Security and performance: proper JWT usage, input validation, guards, caching, and database best practices.

Quick Start

Audit a NestJS project to identify anti-patterns and apply the recommended patterns to refactor for better maintainability and scalability.

FAQPage Schema

How do I structure scalable NestJS modules for better maintainability?▼

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.

What is the best way to apply dependency injection and testing in NestJS?▼

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.

Can I use this to audit an existing NestJS codebase for anti-patterns?▼

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.

Does this NestJS guidance cover security and performance best practices?▼

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.

How do I review NestJS architecture across REST, GraphQL, and TypeORM projects?▼

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.

What are the limitations when refactoring NestJS dependency injection?▼

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.
