SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a principled framework for designing production-grade NestJS backends. It emphasizes modular architecture, robust dependency injection, scalable patterns (CQRS/DDD), and security hardening to help teams build reliable TypeScript server applications.

Core Features & Use Cases

Architectural decision guidance for large NestJS projects (50+ modules) focusing on module boundaries, DI scope, and boundary contracts.
Pattern deep-dives: CQRS, DDD, hexagonal architecture, and dynamic modules with per-feature configuration.
Production-hardening guidance including rate limiting, authentication/authorization, testing with real databases, and migration strategies.

Quick Start

Use this skill to evaluate an existing NestJS monolith or to design a new NestJS module with scalable architecture and secure defaults.

FAQPage Schema

How do I structure a large NestJS backend with proper module boundaries?▼

Structure large NestJS backends by defining strict module boundaries, boundary contracts, and dependency injection scopes to ensure decoupled, maintainable TypeScript architecture for projects with 50+ modules.

What is the best way to implement CQRS and DDD patterns in NestJS?▼

Implement CQRS and DDD in NestJS using dynamic modules with per-feature configuration, applying hexagonal architecture principles to separate command and query responsibilities within enterprise TypeScript backends.

How do I configure NestJS dependency injection scopes for production applications?▼

Configure NestJS dependency injection scopes by evaluating explicit trade-offs and failure modes for each scope, applying per-feature configuration to dynamic modules to balance performance and resource lifecycle management.

How do I add rate limiting and authentication hardening to a NestJS API?▼

Add rate limiting and authentication hardening to NestJS APIs through production-hardening guidance that covers security strategies, authorization flows, and explicit trade-offs for enterprise TypeScript server applications.

Does this NestJS architecture guidance apply to older framework versions?▼

This NestJS architecture guidance satisfies versioned API documentation for NestJS 9+, 10+, and 11+, providing concrete recommendations and migration strategies explicitly tailored to those framework versions.

What testing strategies work best for NestJS modules with real databases?▼

Test NestJS modules with real databases by applying production-hardening testing strategies that validate module boundaries and boundary contracts, ensuring reliable integration coverage for large TypeScript backends.
