What is Dead Code Finder?
Dead Code Finder is a comprehensive static analysis utility designed to streamline modern web development by identifying redundant code. Whether managing a complex monorepo or a standard frontend application, this tool from the Openclaw Skills library parses your codebase to pinpoint functions, types, and entire files that are no longer in use.
By integrating this into your workflow, you can significantly reduce bundle sizes, improve build times, and maintain a cleaner, more navigable repository. It specifically targets the bloat that accumulates over time, such as orphaned components and legacy utility functions that tree-shaking might miss during the build process.
Dead Code Finder Use Cases
- Identifying unused exports in large TypeScript projects using path aliases.
- Auditing package.json to remove bloated or unnecessary npm dependencies.
- Finding orphaned components and legacy files during a major refactor or migration.
- Reducing production bundle sizes by manually tree-shaking dead code identified by the scanner.
- Cleaning up barrel files and index re-exports to resolve complex import cycles.
How Dead Code Finder Works
- The tool parses the project configuration to identify defined entry points like main.ts or index.js.
- It scans all project files while respecting tsconfig path aliases and ignoring specified directories like node_modules or dist.
- A comprehensive reference graph is built to track every import and export across the entire codebase.
- It cross-references imported symbols against exports and checks every file against the global dependency graph.
- A detailed report is generated, highlighting specific lines of code or files that are unreferenced and safe for removal.
Dead Code Finder Setup
To begin optimizing your project with this utility from Openclaw Skills, use the following commands:
# Perform a full scan for unused exports, files, and dependencies
python3 scripts/find_dead_code.py /path/to/project
# Run a targeted scan for unused exports only
python3 scripts/find_dead_code.py /path/to/project --mode exports
# Export the results to JSON for programmatic analysis
python3 scripts/find_dead_code.py /path/to/project --json
Dead Code Finder Data Schema & Taxonomy
The tool organizes findings into three primary categories to help developers prioritize cleanup tasks. The following table describes the data structure of the report:
| Data Category | Description | Examples |
|---|---|---|
| Unused Exports | Exported symbols never referenced in other files. | functions, constants, types, interfaces |
| Unreferenced Files | Files not part of the project's import tree. | legacy components, deprecated utils |
| Unused Dependencies | npm packages listed in package.json but never imported. | moment, lodash.merge, utility libraries |
When using the --json flag, the tool returns a structured object mapping these categories to specific file paths and symbol names.
Dead Code Finder Advanced Features
- Support for TypeScript path aliases and complex monorepo structures.
- Deep analysis of barrel files (index.ts) and complex re-export patterns.
- Customizable entry point detection for frameworks like Next.js (pages/app directories).
- Intelligent filtering to ignore test files, configuration scripts, and documentation by default.
- Ability to handle scoped packages and subpath imports in dependency auditing.
