Opher Vishnia is giving a session of Day 1 of the FullStack 2016 conference (July 13th - 15th, London, UK):
"Firebase is an amazing service that allows you to create real time data sharing in JS between multiple clients. Phaser.io is a javascript library for making games. Opher will be live coding to show you how to use Firebase & Phaser.io to create a multi-player game experience in the browser. Your participation is both mandatory and fun!"
