Rack in Rails

Does Rack come with Rails or do I need to install the gem?

certain version of Rack. Sometimes even an older one than the current.

If in doubt just run:

sudo gem install rails

How do I access rack from a rails app?

Typically, unless you were writing a metal or some rack middleware,
you wouldn’t directly. Rack is (mostly) just the glue between the web
server and rails
