SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams design and maintain scalable Nest.js applications by providing expert guidance on module architecture, dependency injection, middleware, guards, interceptors, and robust testing strategies, along with TypeORM/Mongoose integration and Passport.js authentication. It enables proactive architecture decisions and consistent, maintainable codebases.

Core Features & Use Cases

  • Module Architecture & DI: Design modular Nest.js apps with clean boundaries, reusable providers, and proper export strategy.
  • Middleware, Guards, Interceptors & Pipes: Implement and optimize request lifecycles for security and performance.
  • Testing & Quality: Adopt Jest/Supertest-driven testing, including unit, integration, and e2e patterns for Nest apps.
  • Database & Auth Integration: Guidance on TypeORM/Mongoose integration and Passport.js authentication strategies for secure apps.
  • Use Case: When starting a large Nest.js project, use this skill to define a scalable module structure, DI tokens, and testing plans before coding start.

Quick Start

Provide a Nest.js project description or architectural questions to the agent; I will propose a named module layout, DI patterns, and test strategy.
