There are a massive amount of Phaser boilerplates out there, but this one is extensive to say the least:
- Phaser v2.6.2
- Webpack v2.1.0-beta
- Babel (ECMAScript 2015 + ECMAScript 2016 + Stage 0 of ECMAScript 2017)
- super-event-emitter v4.1.4 as event management
- Typings (Phaser, super-event-emitter) for syntax highlighters
- Task for count line of code (LOC)
- Simple structure for app: constants/, models/, states/
- Put example map (build in Tiled)
- Static directory: public/
It even includes a small sample game. If you're after a boilerplate to get your games started quicker, and want to work in webpack and ES6, this is a great place to start.
