SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill identifies and helps remove unnecessary index.ts files that only re-export a single item, simplifying project structure and reducing maintenance overhead.

Core Features & Use Cases

  • Redundant Barrel Detection: Finds index.ts files that export only one item and are not essential for the project's structure.
  • Structural Simplification: Helps maintain a cleaner and more efficient codebase by removing intermediate export files.
  • Use Case: In a large TypeScript project, this Skill can scan a specified library path to find and report on all redundant barrel files, suggesting direct exports and offering an automated fix.

Quick Start

Run the check-barrel-files skill to analyze the library path 'libs/mxsecurity/account-page'.

Frequently Asked Questions about check-barrel-files

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find redundant index.ts barrel files in a TypeScript project?▼

Redundant barrel files are index.ts files that only re-export a single item. This skill analyzes export statements within a specified TypeScript project path to locate and report these unnecessary intermediate files.

What makes an index.ts barrel file redundant?▼

A barrel file is redundant when it only re-exports a single item. The skill analyzes file content to count export statements and determines redundancy based on export patterns and target file structures.

How do I safely remove unnecessary barrel files and update parent exports?▼

You can safely remove unnecessary barrel files using the skill's automated fix, which updates parent export statements to point directly to the source and deletes the redundant index.ts files.

Can I scan a specific library path for single-item barrel files?▼

Yes, you can scan a specific library path by providing the directory as input. The skill analyzes the specified TypeScript project path to locate and report all redundant barrel files within it.

What are the limitations of refactoring TypeScript barrel files?▼

The refactoring is limited to index.ts files that re-export a single item. Barrel files managing multiple exports or complex structural dependencies are not flagged as redundant and are skipped during analysis.
