SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Backend systems often suffer from unclear boundaries, fragile interfaces, poor validation, and hard-to-maintain code. This skill guides building robust, scalable backend APIs with clean architecture.

Core Features & Use Cases

  • Clear layering: controller/route, service, data access, and validation.
  • RESTful API design and proper status codes.
  • Guidance on stack choices (Node.js, Express, NestJS), databases, and feature requirements.

Quick Start

Create a starter backend API scaffold that exposes a secure REST endpoint using Node.js and Express.

FAQPage Schema
How do I structure a backend API with clean architecture in Node.js or NestJS?

Structure your backend API by enforcing clear architectural layering across controller, service, data access, and validation layers to build maintainable server-side components. This separation prevents fragile interfaces.

What's the best way to design RESTful API endpoints and response shapes?

Design RESTful APIs by applying consistent response shapes, correct HTTP status codes, and clear endpoint definitions. Proper RESTful design ensures robust, production-grade interfaces that are predictable.

Can I use this approach to build authentication systems and data access layers?

Yes, you can build authentication systems and data access layers as core server-side components. The skill guides implementing these features within clean architectural boundaries across Node.js, Express, or NestJS.

How do I scaffold a secure REST endpoint using Express?

Scaffold a secure REST endpoint by creating a starter backend API using Node.js and Express. This quick start approach exposes a foundational, secure endpoint for your server-side application.

Why does my backend system suffer from unclear boundaries and fragile interfaces?

Backend systems suffer from unclear boundaries and fragile interfaces when architectural layering is not enforced. Applying clean architecture with strict controller, service, and validation separation resolves this maintainability issue.
