refactor:express

What problem does it solve?

This Skill helps teams transform legacy Express/Node.js codebases with bloated route handlers and tangled callback logic into clean, modular, testable code using a controller-service-repository pattern and async/await.

Core Features & Use Cases

• Code modularization: extract business logic into services and controllers to separate concerns.
• Async/await refactor: replace callback hell with promise-based control flow and robust error handling.
• Middleware orchestration: establish reusable middleware chains for authentication, validation, and error handling.
• ESM migration: move toward modern ES modules and explicit dependency management for maintainability.
• Use Case: refactor a monolithic route like /users to a controller-service-repository pattern with clear interfaces and testability.

Quick Start

Refactor an existing Express route by moving business logic from the route handler into a dedicated service, wiring the route to call the service, and adding appropriate middleware.
