class 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' #can also set the environment over here config.environment_name = ENV['RACK_ENV'] || "development" 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.
