Knip is a static analysis project cleaner and dead code analyzer for JavaScript and TypeScript projects. It identifies and removes unused files, dependencies, and exports to maintain a lean codebase and reduce bundle size.
The tool functions as a monorepo dependency auditor, tracking exports and dependencies across multiple workspaces to find dead code in large multi-package projects. It specifically targets the removal of unused packages from project manifests and the deletion of unreferenced exports.
Its capabilities cover dead code elimination, JavaScript dependency management, and TypeScript project cleanup. This includes detecting transitive dependencies that are missing from the manifest and identifying orphaned modules or unused types.
