I am writing games in Phaser using webpack for building deployment versions and running hot reload server for development and i am using karma for testing. I am new to most of those technologies so i am open to critique but if someone looks for starting point for connecting Phaser with those technologies i have made git repo that maybe is good starting point to start building your own projects: https://github.com/Xesenix/game-webpack-react-phaser-scaffold
If you are more advanced at using such an environment for developing phaser games I would appreciate advices what i can fix with it
