validate-licenses

Validate licenses of npm modules and fail builds if unapproved licenses exist.

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 validate-licenses --save-dev

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

grunt.loadNpmTasks('validate-licenses');

The "validate_licenses" task

Overview

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

grunt.initConfig({
  validate_licenses: {
    options: {
      // Task-specific options go here.
    },
    out: // name and path to report.json
  }
});

Options

options.blacklist

        "approvedby": "approvers name",
        "approvedon": "date of approval",
        "comment": "reason for approval"

Usage Examples

Default Options

In this example, the default options are used to generate a json report of all production licenses for your project.

grunt.initConfig({
  validate_licenses: {
    options: {},
    out: 'build/licenses.json'
  }
});

Custom Options

In this example, custom options are used to specify that all GPL related licenses are bad.

grunt.initConfig({
  validate_licenses: {
    options: {
      blacklist: [ '.*GPL.*' ]
    },
    out: 'build/licenses.json'
  }
});

In this example, custom options are used to specify that all GPL related licenses are bad, yet [email protected] has been approved for release.

grunt.initConfig({
  validate_licenses: {
    options: {
      blacklist: [ '.*GPL.*' ],
      whitelist: {
        "[email protected]": {
          "approvedby": "Daniel Moran",
          "approvedon": "2016-09-14",
          "comment": "Module allows you to choose between MIT or LGPL."
        }
      }
    },
    out: 'build/licenses.json'
  }
});
