Overview

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

Synopsis:

require 'rack'
require 'errornot_notifier'

ErrornotNotifier.configure do |config|
  config.api_key = 'my_api_key'
end

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

Use a standard ErrornotNotifier.configure call to configure your api key.
