Overview

Middleware for Rack applications. Any errors raised by the upstream application will be delivered to Sentry and re-raised.

Synopsis:

require 'rack'
require 'raven'

Raven.configure do |config|
  config.server = 'http://my_dsn'
end

app = Rack::Builder.app do
  use Raven::Rack
  run lambda { |env| raise "Rack down" }
end

Use a standard Raven.configure call to configure your server credentials.
