knip

What is knip?

Knip is a tool for analyzing and managing unused files and dependencies in your JavaScript and TypeScript projects. It helps you keep your codebase clean and efficient by identifying and removing unnecessary code.

What are knip's main functionalities?

Identify Unused Files

This feature allows you to identify files in your project directory that are not being used. The code sample demonstrates how to use Knip to find unused files in the './src' directory.

const knip = require('knip');

knip.findUnusedFiles({
  directory: './src'
}).then(unusedFiles => {
  console.log('Unused files:', unusedFiles);
});

Identify Unused Dependencies

This feature helps you find dependencies listed in your package.json that are not being used in your project. The code sample shows how to use Knip to find unused dependencies in the current directory.

const knip = require('knip');

knip.findUnusedDependencies({
  directory: './'
}).then(unusedDependencies => {
  console.log('Unused dependencies:', unusedDependencies);
});

Remove Unused Files

This feature allows you to automatically remove files that are not being used in your project. The code sample demonstrates how to use Knip to remove unused files in the './src' directory.

const knip = require('knip');

knip.removeUnusedFiles({
  directory: './src'
}).then(() => {
  console.log('Unused files removed');
});

Remove Unused Dependencies

This feature helps you automatically remove dependencies that are not being used in your project. The code sample shows how to use Knip to remove unused dependencies in the current directory.

const knip = require('knip');

knip.removeUnusedDependencies({
  directory: './'
}).then(() => {
  console.log('Unused dependencies removed');
});

Other packages similar to knip

depcheck

Depcheck is a tool that helps you find unused dependencies in your project. It analyzes your codebase to identify dependencies that are not being used. Compared to Knip, Depcheck focuses more on dependencies and does not provide functionality for identifying or removing unused files.

unimported

Unimported is a tool that helps you find and remove unused files and dependencies in your project. It provides similar functionality to Knip, including the ability to identify and remove unused files and dependencies. However, Unimported may have different configuration options and performance characteristics.

madge

Madge is a tool for visualizing and analyzing the dependency graph of your project. It can help you identify circular dependencies and unused files. While Madge provides some overlapping functionality with Knip, it is more focused on visualizing dependencies and analyzing the structure of your codebase.

README

Knip finds and fixes unused dependencies, exports and files in your JavaScript and TypeScript projects. Less code and dependencies lead to improved performance, less maintenance and easier refactorings.
