I cannot figure out how to integrate existing JavaScript libraries into Volt. With Volt 0.9.3, the Opal Native object is not available, and using only backward steps with interpolation seems unimportant.
You should be able to use native, if you want, in Volt. Controllers are currently mostly loaded on the client side, but they are required on the server side for several reasons, so you need to do:
if RUBY_PLATFORM == 'opal' require 'native' end
Also, have you seen these documents? http://docs.voltframework.com/en/getting_help/can_i_use_jquery_or_other_dom_manipulating_js.html
