Airbrake::Rack

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

Synopsis:

require 'rack'
require 'airbrake'

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

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

use Airbrake::Rack
run app

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