generator-phaser | A yeoman generator for phaser games | Generator Utils library

I am trying to write a small FOSS UI component library for the Phaser.io game engine. The code lives here. In the src/ dir I have a bunch of components that are exported in the index.js file. These components are bundled using the webpack.config.js and exported to build/phaser-ui.js.

I am having trouble using my built file. Inside the test/ directory, I have created a Phaser Game for testing with the phaser-plus Yeoman generator. My phaser-ui package is installed in the test's package.json from a relative link. This seems to work fine.

The issue I am having is that it appears my phaser-ui file does not have access to the Phaser Library. In the test game I am trying to import a component from the phaser-ui package.json dependency, but this causes the following error to be thrown.

Inside the Game.js state:

import ProgressBar from "phaser-ui";
