SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyzes a codebase to identify unused exports, variables, functions, and dependencies, enabling safer cleanup and reduced maintenance burden.

Core Features & Use Cases

Detects unreferenced exports and symbols across files
Suggests safe removal plans with impact checks
Supports refactor workflows by pruning dead code without breaking behavior
Use Case: During a large cleanup, identify and remove unreachable or unused code paths to shrink the codebase and improve readability.

Quick Start

Run the dead-code analysis on your TypeScript or JavaScript project to enumerate unused exports and dead definitions.

FAQPage Schema

How do I find unused exports and dead code in a TypeScript project?▼

Run static analysis across your TypeScript source files to detect unreferenced variables, functions, and dependencies. This identifies unused exports and dead code for safe removal.

What is the best way to clean up dead code during a large refactor?▼

Perform cross-file usage checks to identify unreachable code paths and generate safe deletion plans. This prunes dead code during refactoring without breaking existing behavior.

Can I use static analysis to find unused JavaScript dependencies?▼

Yes, static analysis can find unused JavaScript dependencies by scanning your codebase for unimported modules and unreferenced symbols, which reduces maintenance burden and enables safer cleanup.

Does dead code detection work for Python projects as well as JavaScript?▼

Dead code detection is applicable to both large TypeScript/JavaScript and Python projects. It identifies unused exports, variables, functions, and dependencies across the entire codebase.

How do I prevent regressions when removing unreachable code paths?▼

Prevent regressions when removing unreachable code paths by following safe deletion guidance with impact checks. You can also verify changes via tests to ensure no broken behavior.

When should I run a dead code analysis on my codebase?▼

Run a dead code analysis during cleanup sprints, refactors, or onboarding to reduce technical debt. It identifies and removes unreachable or unimported code safely across your project.
