Safely refactor large Nodejs route files by following a staged structural refactoring process that prioritizes planning before coding, splitting massive route files into smaller controllers and routes while ensuring existing functionality never breaks.

Introducing a service layer in a Javascript web application requires a staged structural refactoring approach that extracts business logic from routes into dedicated services. This architectural pattern improves code quality and maintainability without breaking existing functionality.

Fix duplicated model functions during architectural refactoring by merging them into unified service layer components. This structured process addresses documented architectural violations, extracting business logic to eliminate duplication while maintaining existing application behavior.

This refactoring approach is not suitable for general Nodejs maintenance tasks, as it is strictly designed for Group 3 architectural refactoring tasks. It specifically targets documented violations like large route files, missing service layers, and duplicated logic.

You need a documented violation report, such as a report.md file, before starting a staged structural refactoring. The Skill guides fixes for specific architectural violations identified in the report, ensuring targeted improvements to code quality and maintainability.
