node-license-sniffer

node-license-sniffer is a tool for detecting the license of node packages. It will attempt to read the license from package.json. If it cannot find the license in package.json, it will read LICENSE and similarly named files and attempt to guess the license in use.

Installation

npm install license-sniffer

Usage

node-license-sniffer [package-dir] [--js-comment] [--recurse] [--body]

Arguments:

  • package-dir -- the directory of the package. Defaults to the current directory.
  • --js-comment -- prepend all output with //. Useful if generating license information for inclusion in JavaScript files.
  • --recurse -- find the license for the specified package, and its dependencies.
  • --body -- include the body of each license where possible.

Examples

Running node-license-sniffer in its own directory:

$ node-license-sniffer
BSD

Using --js-comment and --body (truncated for brevity):

$ node-license-sniffer --js-comment --body
