Hi,
I am currently thinking of a multiplayer game written completely in cocos2d-html5. But for this I need to run the server part of the game without a webbrowser. Is this possible in cocos2d-html5? Maybe running cocos2d-html5 with node?
Hello Daniel,
Cocos2d-html5 will help you making the client for your game, but the server needs to reside somewhere! and cannot be inside a webbrowser.
However, there is an alternative for writing a game server with Javascript, which is node.js (http://www.nodejs.org). You could combine it with a cloud app server (such as Heroku) to have something to experiment. Expect to pay for Heroku if you publish your game and gets popular 
Does this answer your question?
Regards,
Ciro.
