What is the best way to clean up unused dependencies in a JavaScript monorepo?▼

Unused dependencies in a JavaScript monorepo are cleaned up through automated analysis tools like Knip. This Skill provides configuration guidance for monorepo setups to systematically identify and remove uncalled code and dependencies.

Can I integrate dead code detection into my CI pipeline?▼

Dead code detection can be integrated into your CI pipeline to maintain code hygiene and reduce technical debt. Knip performs automated analysis to catch unused dependencies and configuration issues during continuous integration.

Does Knip work with both JavaScript and TypeScript codebases?▼

Knip works with both JavaScript and TypeScript codebases to detect dead code and configuration issues. It addresses scenarios involving code cleanup and performance optimization for both single projects and monorepos.

How do I configure Knip for a large codebase refactoring?▼

Configuring Knip for a large codebase refactoring involves setting up the tool to systematically identify unused code and dependencies. This Skill provides best practices for various project setups to guide remediation and improve maintainability.

Why should I remove unused exports and files from my codebase?▼

Removing unused exports and files from your codebase leads to cleaner, more efficient, and maintainable projects. Eliminating dead code reduces technical debt, shrinks bundle size, and improves overall performance.
