Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fallow) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

fallow

Find dead code in JavaScript and TypeScript projects. Written in Rust.

Fallow detects unused files, exports, dependencies, types, enum members, and class members across your codebase. It is a drop-in alternative to knip that runs 25-50x faster on real-world projects by using the Oxc parser instead of the TypeScript compiler.

Installation

npm install -g fallow

Usage

# Analyze your project
fallow check

# Watch mode
fallow watch

# Auto-fix unused exports and dependencies

Unused enum members - enum variants never accessed
Unused class members - methods/properties never used
Unresolved imports - imports that don't resolve to a file
Unlisted dependencies - imported packages not in package.json
