grunt-licensechecker

This plugin will test if licenses in your project are in a list of acceptable licenses. If it is not you can output the list of unacceptable licenses to the screen as a warning and/or output to a file of your choice.

Getting Started

This plugin requires Grunt ~0.4.5

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-licensechecker --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-licensechecker');

The "licensechecker" task

Overview

In your project's Gruntfile, add a section named licensechecker to the data object passed into grunt.initConfig().

grunt.initConfig({
  licensechecker: {
    options: {
      warn: true,
      outFile: null,
      acceptable: [ 'MIT', 'MIT/X11', 'BSD', 'ISC' ] 
    }
  },
});

Options

options.warn

Type: Boolean Default value: false

If this is set to true then you'll receive a warning while grunt is running stating that there is a license that is not in the list of acceptable licenses.

options.outFile

Type: String Default value: null

If outFile is passed then a markdown formatted file will be output which shows all licenses which do not match the acceptable licenses and also lists libraries which do not have a license. If null is passed or this is left blank no file will be output.

options.acceptable

Type: Array{String}

You must pass an array of acceptable licenses for instance [ 'MIT', 'BSD', 'ISC' ].

options.include

Type: Array{String}|String Default value: 'all'

The types of dependencies to include, such as: ['dependencies', 'devDependencies', 'peerDependencies'].

Usage Examples

To Screen

In this example licenses which are are not [ 'MIT', 'MIT/X11', 'BSD', 'ISC' ] will be output to screen.

The license checked will only be for dependencies.

grunt.initConfig({
  licensechecker: {
    options: {
      warn: true,
      outFile: null,
      acceptable: [ 'MIT', 'MIT/X11', 'BSD', 'ISC' ],
      include: 'dependencies' 
    }
  }
});

To Markdown File

In this example libraries which are not acceptable and libraries which do not have a license defined in the package.json are output to a file called LICENSE.md.

grunt.initConfig({
  licensechecker: {
    options: {
      outFile: 'LICENSE.md',
      acceptable: [ 'MIT', 'MIT/X11', 'BSD', 'ISC' ] 
    }
  }
});
