SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Large JavaScript/TypeScript files are hard to maintain and understand. This Skill automates modularization by splitting code into components, routes, or state-based modules while preserving the original logic, following the guideline of keeping modules around 130 lines.

Core Features & Use Cases

  • Automatic splitting by export, function, and class boundaries to create modular parts (roughly under 130 lines for AI-friendly editing).
  • Three refactoring strategies: components, routes, and state-based splits.
  • Maintains original behavior and enables incremental refactoring to improve readability and scalability.

Quick Start

Run the modularizer on a target JS/TS file to generate modular parts according to the chosen strategy.

FAQPage Schema
How do I automatically split large JavaScript files into smaller modules?

To split large JavaScript files into smaller modules, this Skill detects export, function, and class boundaries to separate code into modular parts while preserving the original logic.

What is the best way to refactor a monolithic TypeScript codebase into components?

Refactoring a monolithic TypeScript codebase into components is achieved by applying a component-based split strategy, which automatically divides large files into modular units around 130 lines.

How does modularization preserve the original behavior of a JavaScript file?

Modularization preserves original behavior by detecting existing code boundaries and separating the logic into distinct modular files without altering the underlying functionality.

Can I split JavaScript files based on routes or state management?

Yes, you can split JavaScript files based on routes or state management by selecting the route-based or state-based refactoring strategies provided by the modularization process.

Why does automated JavaScript modularization target modules around 130 lines?

Automated JavaScript modularization targets modules around 130 lines to enforce readability and create AI-friendly editing units that improve maintainability.

Does this modularization tool require specific dependencies to refactor TypeScript files?

No specific dependencies are required to refactor TypeScript files, as the modularization operates directly on the JavaScript and TypeScript codebase using built-in scripts and references.
