nlf

Node License Finder (nlf)

nlf is a utility for attempting to identify the licenses of modules in a node.js project.

It looks for license information in package.json, readme and license files in the project. Please note, in many cases the utility is looking for standard strings in these files, such as MIT, BSD, Apache, GPL etc - this is not error free, so if you have any concerns at all about the accuracy of the results, you will need to perform a detailed manual review of the project and its dependencies, reading all terms of any included or referenced license.

Use

nlf can be used programatically, or from the command line.

Programatically

var nlf = require('nlf');

var results = nlf.find('/User/me/my-project', function (err, data) {
	// do something with the response object.
	console.log(JSON.stringify(data));
});

I will document the response object at some point, but it should be fairly straight forward.

Note, if you run nlf programatically having installed it locally, it will find various spurious false positives from its own test data. So exclude the results from the nlf record.

CLI

To install:

$ npm install -g nlf

To use:

$ cd my-module
$ nlf

Tests

To run the npm unit tests, install development dependencies and run tests with 'npm test' or 'make'.

If you contribute to the project, tests are written in mocha, using should.js or the node.js assert module.

$ cd nlf
$ npm install
$ npm test
