IANAL - check your licenses

Note: I am not a lawyer and this is not legal advice

Discover the license of the npm packages that you are using easily: Just install it globally and run it in your project folder:

npm install ianal -g && ianal

Documentation

There are a couple of special cases:

• -: the file where we are trying to locate the license couldn't be found, or the license itself couldn't be found.

• ? verify: the license file was found and there's strong suggestions that there might be a license, but we just couldn't parse it automatically.

FAQ

It says 'No modules installed'

Make sure that you are in the root folder for your project; doing ls you should be able to see node_modules

Does it check all modules by npm?

Not exactly, it does check all of the modules in node_modules except those that start by ., but it doesn't go deep checking sub-modules

What licenses does it check?

It attempts to find MIT, BSD and ISC, and then there's a regex that attempts to find other licenses automatically. This list is short, so please feel free to expand it:

var licenseRegex = [

  // Some defaults with non-capturing groups (?:)
  { name: 'MIT', regex: /(?:The )?MIT(?: (L|l)icense)/ },
  { name: 'BSD', regex: /(?:The )?BSD(?: (L|l)icense)/ },
  { name: 'ISC', regex: /(?:The )?ISC(?: (L|l)icense)/ },

  // This will attempt to capture the name and display it
  { name: false, regex: /(?:The )?([\w-/\.]{3,}?) (L|l)icense/ }
];

Another idea is that we could add a part of the license text to the regex, so the match is more 'secure'. It works pretty well for my purposes right now though.
