NPM License Concatenator

Looking to make an electron app and can't be bothered with putting together licenses?

This package searches for licenses in node project dependencies and creates a library license file that can be used for redistributable packages.

This package is based off davglass/license-checker and uses its functionalities for finding licenses.

With the detection of licenses, it follows davglass/license-checker, with the exception that guesses are enabled for explicitly named LICENSE files only. Any other license guesses such as from README are not allowed and will produce a warning. A warning is also given if the file is missing or inaccessable.

Usage

Module Use

The package can be required for use in another node module. One async function is exposed for use. Async functions return a promise, so the .then() syntax can also be used.

const concatLicenses = require("concat-licenses").concat;

(async () => {
  const output = await concatLicenses({
    ignoreMissing: false,
    allowGuess: false,
    includeCurrent: false,
    title: "LICENSES FOR SOFTWARE PACKAGES\n\n",
    start: process.cwd(),
    production: false,
    development: false,
    packages: "",
    excludePackages: "",
    excludePrivatePackages: "",
    direct: false,
  });
})();

The output will be the formatted text string that is usually written to a file.
