SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

NestJS Best Practices codifies architectural guidelines and design patterns to help teams build scalable, maintainable, and secure NestJS applications. It provides a centralized reference for module organization, dependency injection discipline, error handling, and performance strategies that reduce runtime issues and onboarding time.

Core Features & Use Cases

  • Architecture and module organization guidance (feature modules, proper exports/imports, and shared modules).
  • Dependency injection discipline (constructor injection, DI tokens, interface segregation, and LSP adherence).
  • Security and API quality (JWT auth, validation, guards, DTO serialization, rate limiting, and XSS prevention).
  • Performance and database patterns (async hooks, caching, transactions, migrations, and lazy loading).
  • Testing and microservices patterns (testing modules, queues, events, health checks, and e2e/testing strategies).

Quick Start

Apply this guide during reviews to systematically refactor a NestJS codebase toward modular architecture, constructor DI, secure authentication, and performance improvements.

Frequently Asked Questions about nestjs-best-practices

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I structure NestJS modules for scalable architecture?▼

Apply constructor injection and use DI tokens with interface segregation in NestJS to enforce explicit dependency injection contracts, adhering to Liskov Substitution Principle for maintainable code.

What is the best way to secure a NestJS API with JWT and validation?▼

Secure a NestJS API by implementing JWT authentication, validation pipes, guards, DTO serialization, rate limiting, and XSS prevention to ensure centralized secure API design and robust data protection.

How do I handle errors centrally in NestJS applications?▼

Handle errors centrally in NestJS by implementing centralized error handling patterns that catch runtime issues systematically, reducing onboarding time and ensuring robust code quality across feature modules.

Can I use NestJS best practices for performance and database optimization?▼

Apply NestJS performance patterns using async hooks, caching, transactions, migrations, and lazy loading to optimize database access and ensure testable data access patterns in scalable applications.

How do I test NestJS microservices with queues and events?▼

Test NestJS microservices by configuring testing modules for queues, events, and health checks, employing e2e testing strategies to validate robust microservice interactions and ensure code reliability.
