    License Report

    Generates license reports of 3rd-party software dependencies

    Looks through a project's npm dependencies (and optionally devDependencies and Bower dependencies), pulls out licensing information, and compiles it into a given template.

    const licenser = require('ux-license-report');
    let report = licenser.generateReport();
    console.log(report.toString()); // print it to the console
    report.write('report.txt'); // saves the report to a file



    Returns a Promise that resolves to the generated report.


    • context: Object of values (indexed by property) to add to the template. Default is {}.
    • include: Array of npm (for package.json dependencies), dev (for package.json devDependencies), and/or bower (for bower.json dependencies). Default is ['npm'].
    • path: The root path of the project.
    • template: Lodash template string to use when rendering. Default is in template.txt.

    The returned report object has the following properties:

    • toString(): Returns the compiled report.
    • warnings: An array of any warnings that occurred.
    • write(filename): Saves the compiled report to a file.


    If you have this module installed globally or inside another project, you can call it on the command line from the generate-license-report.js script:

    $ ./generate-license-report.js [ROOTPATH]
         [--include npm] [--include dev] [--include bower]
         [--template FILE]
         > licenses.txt

    If the root path is not specified, the current working directory is used. The default values for other options are the same as the API.

    All options are passed through to the template, so you can add to the context by passing scalar values or JSON strings. For example: ./generate-license-report.js --foo 1 --bar '{"bar": "value"}'.

    The generated report sent to standard output (stdout), so you can save it by redirecting it to a file (as shown in the example above). Any errors or warnings are sent to standard error (stderr).

    Call the script with the --help option (./generate-license-report.js --help) to see the usage info.


    Please add tests and maintain the existing styling when adding and updating the code.

    yarn lint  # run linting
    yarn test  # run tests
