Hello,
I'm actually just getting started making games, and Phaser looks like a pretty cool place to start. I've actually created lots of web servers the past couple years using Go, and just how easy and lightweight the language is for doing exactly that. So I thought it would be perfect for creating dev servers like you have to do for phaser testing / debugging. So, I wrote a little program that does just that.
https://github.com/Noofbiz/GoPhaser
It requires Go to be installed, and is similar to using Flask in Python for the same effect. If anyone wants to check it out and has any questions, feel free to ask here.
Thanks!
