Overview

This skill ensures clean, maintainable, production-ready Node.js code. It covers Express application structure, PostgreSQL database patterns, error handling, testing, and security.

Project Structure

Organize code into distinct layers:

server/
├── index.js           # App setup, middleware mounting
├── routes/            # HTTP handling only, no business logic
├── services/          # Business logic, database operations
├── data/              # Static data, definitions, constants
├── db/                # Database connection, migrations
└── auth/              # Authentication middleware
