Package Exports

license-checker
license-checker/lib/license

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (license-checker) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

NPM License Checker

Ever needed to see all the license info for a module and it's dependencies?

It's this easy:

npm install -g license-checker

mkdir foo
cd foo
npm install yui-lint
license-checker

You should see something like this:

├─ cli@0.4.3
│  ├─ repository: http://github.com/chriso/cli
│  └─ licenses: MIT
├─ glob@3.1.14
│  ├─ repository: https://github.com/isaacs/node-glob
│  └─ licenses: UNKNOWN
├─ graceful-fs@1.1.14
│  ├─ repository: https://github.com/isaacs/node-graceful-fs
│  └─ licenses: UNKNOWN
├─ inherits@1.0.0
│  ├─ repository: https://github.com/isaacs/inherits
│  └─ licenses: UNKNOWN
├─ jshint@0.9.1
│  └─ licenses: MIT
├─ lru-cache@1.0.6
│  ├─ repository: https://github.com/isaacs/node-lru-cache
│  └─ licenses: MIT
├─ lru-cache@2.0.4
│  ├─ repository: https://github.com/isaacs/node-lru-cache
│  └─ licenses: MIT
├─ minimatch@0.0.5
│  ├─ repository: https://github.com/isaacs/minimatch
│  └─ licenses: MIT
├─ minimatch@0.2.9
│  ├─ repository: https://github.com/isaacs/minimatch
│  └─ licenses: MIT
├─ sigmund@1.0.0
│  ├─ repository: https://github.com/isaacs/sigmund
│  └─ licenses: UNKNOWN
└─ yui-lint@0.1.1
   ├─ licenses: BSD
      └─ repository: http://github.com/yui/yui-lint

An asterisk next to a license name means that it was deduced from an other file than package.json (README, LICENSE, COPYING, ...) You could see something like this:

└─ debug@2.0.0
   ├─ repository: https://github.com/visionmedia/debug
   └─ licenses: MIT*

Options

--production only show production dependencies.
--development only show development dependencies.
--unknown report guessed licenses as unknown licenses.
--onlyunknown only list packages with unknown or guessed licenses.
--json output in json format.
--csv output in csv format.
--csvComponentPrefix prefix column for compoment in csv format.
--out [filepath] write the data to a specific file.
--customPath to add a custom Format file in JSON
--exclude [list] exclude modules which licenses are in the comma-separated list from the output
--relativeLicensePath output the location of the license files as relative paths

Examples

license-checker --json > /path/to/licenses.json
license-checker --csv --out /path/to/licenses.csv
license-checker --unknown
license-checker --customPath customFormatExample.json
license-checker --exclude 'MIT, MIT/X11, BSD, ISC'
license-checker --onlyunknown

Custom format

The --customPath option can be used with CSV to specify the columns. Note that the first column, module_name, will always be used.

When used with JSON format, it will add the specified items to the usual ones.

The available items are the following:

name
version
description
repository
publisher
email
url
licenses
licenseFile
licenseText
licenseModified

You can also give default values for each item. See an example in customFormatExample.json.

Requiring

var checker = require('license-checker');

checker.init({
    start: '/path/to/start/looking'
}, function(err, json) {
    if (err) {
        //Handle error
    } else {
        //The sorted json data
    }
});

Debugging

license-checker uses debug for internal logging. There’s two internal markers:

license-checker:error for errors
license-checker:log for non-errors

Set the DEBUG environment variable to one of these to see debug output:

$ export DEBUG=license-checker*; license-checker
scanning ./yui-lint
├─ cli@0.4.3
│  ├─ repository: http://github.com/chriso/cli
│  └─ licenses: MIT
