Do you need to pass command line arguments dynamically to a package.json script? This is how to do it.

Static command line arguments can be set with the scripts.

  ...
  "scripts": {
    "cli": "node ./src/build-helper-cli.js -V"
  }
  ...

The script can be called as follows.

 $ npm run cli

Now lets pass it a command line argument dynamically.

$ npm run cli -- add-eslint-disable --dest build

The trick are the two dashes (–) which tell npm what follows are command line arguments for the script being executed. That is it. Easy right?
