Undeps

Undeps is a tool for detect unused dependencies, by default it takes all dependencies and check if the package name exists in files. To make the tool more strict you can change the checkFn, e.g check for import or require

It will also exclude some dependencies:

• @types/ packages
• packages with binaries
• exclude array
• excludeFn function

You can configure the tool for your needs with undeps.config.js

Installation

npm install -g undeps

Config

Filename: undeps.config.js

Default config:

module.exports = {
  binaries: false, // set to true to include binaries dependencies in the search, default is to ignore
  checkFn: (dep, file) => file.body.indexOf(dep) !== -1, // dep = e.g webpack, file = { name, path, body }
  exclude: [], // deps to exclude, e.g webpack
  excludeFn: (dep) => true, // dep = e.g webpack,
  files: [], // path to files to include, e.g ./babel.config.js
  pattern: `${cwd}/src/**/*.+(js|ts|jsx|tsx|vue)`,
  packages: `${cwd}/{package.json,packages/**/package.json}`,
  types: false, // set to true to check for @types/* deps, default is to ignore
};
