In order to help me and others with starting game development with phaser.io and TypeScript, I have created a boilerplate project on github: http://github.com/wlk/phaser-typescript-boilerplate that can be used to jump-start game development.
Just clone or download a zipped archive of the repository, then start writing your game - README file has more detailed information how to use it.
I have added following components:
npm commands for running project in development and production mode
directory/file structure that makes some sense in the beginning
Project is working very well with Intelllj IDEA (also WebStorm) but you can also use all CLI tools you are already familiar with.
