Construct 2 and heroku

First post, so excuse any inanities, frequently asked stuff, etc.. I have searched around but haven't found answers to this.

I'm making a facebook app and would like to take advantage of the hosting on heroku - since it's well integrated with FB and free at least at first.

But I can't work out how to do it - seems to require you to register with one of either ruby, PHP etc.

I don't know which of those to accept and I don't understand where the Construct 2 export interfaces. Do you need to write a container for the html5? Does anyone know how to do that.

Thanks in advance.

I'd advise you to move away from Heroku, not because it's bad or anything, but because they'll offer you many things you won't use/need, and you'll still have to pay the price.

If you *MUST* work with heroku, I'd advise you to pick PHP hosting, since you won't have to change anything to host your game.

Do keep in mind you'll be paying for PHP functionality even though you won't use it.
