It’s time to add some multiuser interactivity to canvas. And here is the next demo based on famous game characters. Your character is Mario and Luigis - other users watching this demo. Use keyboard arrows or virtual joystick for touch devices - moves character. Also you can type any message and other user will see it. All this made with CreateJS (client), SockJS (client-server) and NodeJS (server). And finally I managed how to use runit and NodeJS together for easily start/stop/restart/auto-restart-in-case-of-fault server.
