Q:

When building HTTP API with Rails 3.2, should I disable front end things such as .js files?

When building HTTP API which respond only JSON format with Rails 3.2, should I turn off things like Asset Pipeline and javascript files?
If so, how to do it correctly instead of manually deleting which sounds dirty?

A:

Probably a good idea if you're only serving up the api, here's how:
rails new appname --skip-sprockets

For an existing application, in your application.rb:
config.assets.enabled = false
