depcheck (dependency-checker)

depcheck is a small package to find duplicate dependencies in your node_modules. This project is inspired by find-duplicate-dependencies by Vladimir Guguiev.

Install

$ npm install @webkits/depcheck

Usage

CLI

depcheck [options] [package-name-1] [...] [package-name-n]

Analyze and find the duplicates packages in node_modules. If no package names
are provided, it will check all the dependencies.

Options:
      --version  Show version number                                   [boolean]
  -v, --verbose  Display the duplicate packages in details with their version
                 and caller path                                       [boolean]
  -h, --help     Show help                                             [boolean]

This command exits with 1 if there are some duplicates and with 0 if there are not.

Example 1: Check all the dependencies

$ depcheck

Example 2: Check some dependecies

$ depcheck -v -- lodash react
