This is Rack middleware that sends request/response data to Honeycomb. You can use Rack::Honeycomb with any Ruby web framework based on Rack, including Ruby on Rails and Sinatra.

For more information about using Honeycomb, check out our docs and our Ruby SDK.

Attaching the middleware is simple. Inside handlers, you also have the choice of attaching custom fields to be added to the events sent to Honeycomb.

#!/usr/bin/env ruby -rubygems
require 'sinatra'
require 'rack/honeycomb'

use Rack::Honeycomb::Middleware, writekey: "<YOUR WRITEKEY HERE>", dataset: "<YOUR DATASET NAME HERE>", is_sinatra: true

get('/hello') do
  Rack::Honeycomb.add_field env, :greeting, 'hello'
  "Hello, world!\n"
end

For more fully-featured Rails support, see beeline-ruby.

beeline-ruby includes this gem along with active record support.

If beeline-ruby doesn't work for you, you can include this middleware standalone

# config/application.rb
require 'rack/honeycomb'

class Application < Rails::Application
  config.middleware.use Rack::Honeycomb::Middleware, writekey: "<YOUR WRITEKEY HERE>", dataset: "<YOUR DATASET NAME HERE>", is_rails: true
end

To install the latest stable release of rack-honeycomb, simply:

$ gem install rack-honeycomb

or add this to your Gemfile

gem "rack-honeycomb"

To follow the bleeding edge, it's easy to track the git repo:

gem "rack-honeycomb", :git => "https://github.com/honeycombio/rack-honeycomb.git"
