SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers systematically refactor large or complex codebases to improve maintainability, reduce file sizes, and eliminate duplication.

Core Features & Use Cases

  • Identify Duplication: Finds and helps extract repeated code patterns.
  • Extract Utilities/Components: Guides in splitting code into reusable functions and components.
  • Split Large Files: Provides strategies for breaking down monolithic files.
  • Organize Codebase: Promotes architectural patterns like "Thin Layers".
  • Use Case: You have a SvelteKit project where several pages share the same filtering and sorting logic for tables. This Skill can help you extract that logic into a shared utility function, making your code DRY and easier to manage.

Quick Start

Use the code-refactoring skill to help me extract duplicated filtering logic from these two files: src/routes/expenses/+page.svelte and src/routes/mileage/+page.svelte.

FAQPage Schema
How do I refactor large TypeScript files into focused modules?

To refactor large TypeScript files, you split monolithic structures into focused modules by extracting reusable utilities and components, applying architectural patterns like Thin Layers to improve code maintainability and reduce file sizes.

What is the best way to eliminate code duplication in a SvelteKit project?

Eliminating code duplication in a SvelteKit project involves identifying repeated filtering and sorting logic across pages, then extracting those patterns into shared utility functions to make your codebase DRY and easier to manage.

Can I use this refactoring approach for React applications as well?

Yes, you can use this refactoring approach for React applications. The strategies for extracting reusable utilities, splitting large files, and applying Thin Layers architectural patterns are applicable to SvelteKit, React, and TypeScript projects.

How do I extract shared table filtering logic from multiple SvelteKit pages?

To extract shared table filtering logic from multiple SvelteKit pages, you identify the duplicated code in files like your page routes, then consolidate that logic into a shared utility function to improve code organization and maintainability.

When should I apply the Thin Layers architectural pattern during code organization?

You should apply the Thin Layers architectural pattern when organizing code to systematically reduce file sizes, eliminate duplication, and split large monolithic files into focused modules for better overall code maintainability.
