Sections
This file defines all sections, their ordering, impact levels, and descriptions. The section ID (in parentheses) is the filename prefix used to group rules.
1. Architecture (arch)
Impact: CRITICAL Description: Proper module organization and dependency management are the foundation of maintainable NestJS applications. Circular dependencies and god services are the #1 architecture killer.
2. Dependency Injection (di)
Impact: CRITICAL Description: NestJS's IoC container is powerful but can be misused. Understanding scopes, injection tokens, and proper patterns is essential for testable code.
3. Error Handling (error)
Impact: HIGH Description: Consistent error handling improves debugging, user experience, and API reliability. Centralized exception filters ensure uniform error responses.
4. Security (security)
Impact: HIGH Description: Security vulnerabilities can be catastrophic. Input validation, authentication, authorization, and data protection are non-negotiable.
5. Performance (perf)
Impact: HIGH Description: Optimizing request handling, caching, and database queries directly impacts application responsiveness and scalability.
6. Testing (test)
Impact: MEDIUM-HIGH Description: Well-tested applications are more reliable. NestJS testing utilities enable comprehensive unit and e2e coverage.
7. Database & ORM (db)
Impact: MEDIUM-HIGH Description: Proper database access patterns, transactions, and query optimization are crucial for data-intensive applications.
8. API Design (api)
Impact: MEDIUM Description: RESTful conventions, versioning, DTOs, and consistent response formats improve API usability and maintainability.
9. Microservices (micro)
Impact: MEDIUM Description: Building distributed systems requires understanding message patterns, health checks, and inter-service communication.
10. DevOps & Deployment (devops)
Impact: LOW-MEDIUM Description: Configuration management, structured logging, and graceful shutdown ensure production readiness and zero-downtime deployments.
