I'm just looking at the possibilities in Node.js web development. I'm used to coding in ASP.NET MVC 3, so TowerJS and Geddy looks friendly and familiar to me (because of the MVC pattern)
However I don't really like CoffeeScript (because of its strange syntax and the debugging issues), so I would be happy if I could use Tower without using CoffeeScript - and if I could use simple JavaScript instead. Is it possible? If I go to their website, I see CoffeeScripts everywhere...
(I would be happy, if I also could use another templating engine (because CoffeeKup uses CoffeeScript as well), and I change it into a more Razor-like engine.)
Currently Tower development is done using coffeescript. A javascript api is planned for the future, though I don't know how far off that is. There are a few complications to work out, before that will be possible.
EDIT: Adding a Javascript API to Tower has become a priority for the framework, so I expect this to come to fruition sooner than I had anticipated when I originally answered. Probably quite soon.
