Knip: Declutter Your JavaScript & TypeScript Projects
Knip is a powerful project linter designed to identify unused dependencies, exports, and files in JavaScript and TypeScript projects. It helps developers maintain cleaner, more efficient codebases by highlighting areas of potential improvement.
Key Features:
- Unused Dependency Detection: Identifies npm packages that are installed but not actively used in the project.
- Unused Export Detection: Finds exported functions, classes, or variables that are never imported or utilized elsewhere in the codebase.
- Dead File Elimination: Locates files that are not part of the project's dependency graph and can be safely removed.
- Framework & Tooling Plugins: Supports a wide range of tools and frameworks, including React, Next.js, TypeScript, ESLint, and more, through dedicated plugins.
- Monorepo Support: Efficiently analyzes and optimizes large, multi-package repositories.
- Configuration Flexibility: Offers extensive configuration options to tailor the analysis to specific project needs.
Use Cases:
- Codebase Maintenance: Regularly identify and remove dead code to reduce complexity and improve maintainability.
- Dependency Management: Ensure that only necessary packages are included in the project, minimizing bundle size and improving performance.
- Refactoring: Simplify refactoring efforts by identifying unused code that can be safely removed or modified.
- CI/CD Integration: Integrate Knip into continuous integration pipelines to automatically enforce code cleanliness standards.
