Rails 3 + coffeescript is amazing and I see going in a more object oriented direction with js now. That lends to passing data to my app via json objects, at least in the case I am currently looking at.
However, it seems the cost (other than a learning curve), is the loss of the benefits that Rails view rendering provides, such as all the helpers, etc. This is what is good about Pivotal’s approach. Not excited at all to go back to manually rendering and maintaining select boxes, for example. Is there a way to keep some benefit of helpers but going this route, but perhaps in another js library???
So… if anyone has experience or comments would love to hear. Any drawbacks to going this route with Rails – confirmation of what I write above or other problems I have not thought of? Also, from what I see jQote2 is the fastest out there… anyone using?
