Overview

Returns a user-friendly exception page Should be included at the very top of the middleware pipeline so that unhandled exceptions from anywhere down the pipeline are rescued In development, you’d want to use Rack::ShowExceptions instead of this (config.ru example):

if ENV['RACK_ENV'] == 'development'
  use Rack::ShowExceptions
else
  use Rackables::HideExceptions
end

The default HTML included here is a copy of the 500 page included with Rails You can optionally specify your own file, ex:

use Rackables::HideExceptions, "public/500.html"
