license-compatibility-checker

Check npm dependencies' package.json for license compatibility (aka compliance check) with the current project based on spdx notation and naming conventions.

This is WIP and likely to change but already useable.

Does a simple comparison like Public Domain > Permissive > Weakly Protective > Strongly Protective > Network Protective of the primary dependencies in nodemodules (no recursive search). Checks for unlicensed or unknown licenses. Screenshot with sample data (some licenses changed for demo) ```sh npm install license-compatibility-checker -g ``` or better ```sh npm install license-compatibility-checker --save-dev ``` or ```sh npm install https://github.com/HansHammel/license-compatibility-checker.git --save-dev ```

CLI

In your project folder run ```bash license-compatibility-checker ``` or ```bash lcc PATHTOPACKAGEJSON ``` or (win) ```bash .\nodemodules\.bin\lcc ..\droppy\package.json c:/l/droppy/nodemodules ``` or (nix) ```bash ./nodemodules/.bin/lcc PATHTOPACKAGEJSON PATHTOMODULES ``` etc. Supports to optional parameters:

1. path to package json (defaults to ./package.json)

1. path to nodemodules (defaults to ./nodemodules)

Paths can be relative to the CWD and/or mixed Win/nix-style

//No license issues found

console.log(output);
