SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams reduce code duplication in TypeScript and JavaScript projects, improving maintainability and readability while preserving existing behavior.

Core Features & Use Cases

  • Detect duplicate patterns across modules and components and highlight refactoring opportunities.
  • Extract shared utilities, hooks, or components to create a single source of truth and simplify maintenance.
  • Guide disciplined refactoring that enforces DRY/KISS principles and modern TS/JS practices.
  • Use case: In a large React/Node project with repeated data fetch or validation logic, consolidate into reusable utilities.

Quick Start

Identify a duplicated function or class, extract it into a shared module (e.g., src/utils/), and replace all references with the shared implementation.

FAQPage Schema
How do I reduce code duplication in a large TypeScript project?

To reduce code duplication in TypeScript, identify repeated patterns across modules and extract them into shared utilities, hooks, or components. This enforces DRY principles and creates a single source of truth while preserving existing behavior.

What is the best way to refactor shared data fetch logic in React and Node?

The best way to refactor shared data fetch logic is to consolidate the repeated implementations into reusable utilities within a shared module like src/utils. You then replace all existing references with this extracted shared implementation to simplify maintenance.

Can I use this refactoring approach on medium-to-large JavaScript codebases?

Yes, you can apply this refactoring approach to medium-to-large JavaScript codebases. It is designed for projects with multiple modules, utilities, hooks, or components that share logic, helping improve maintainability and readability without altering functionality.

How do I extract a duplicated function into a shared module?

To extract a duplicated function into a shared module, identify the repeated logic, move it into a centralized file such as src/utils/, and replace all original references with imports from that new shared implementation to establish a single source of truth.

Does this DRY refactoring approach preserve existing application behavior?

Yes, this DRY refactoring approach preserves existing application behavior. It focuses on improving maintainability and enforcing modern TS/JS practices while ensuring the functional output of the consolidated utilities, hooks, or components remains identical.
