analytic

Analytic

Analytic provides visitor / session / view tracking without the need for any third-party service.

Installation

$ bundle add analytic
$ bin/rails analytic:install:migrations
$ bin/rails db:migrate

# config/routes.rb
Rails.application.routes.draw do
  mount Analytic::Engine, at: '/analytic'
end

Usage

Default inline tracking is configured with:

class ApplicationController
  include Analytic::Trackable

  before_action :analytic_track!, if: -> { request.format.html? }
end

Alternative job tracking is configured with:

class ApplicationController
  include Analytic::Trackable

  before_action :analytic_enqueue_track_job!, if: -> { request.format.html? }
end

note: a queue such as sidekiq, rescue, etc must be running to see tracking

Configuration

Authentication the Dashboard

By default Analytic is not authenticated. To authenticate using Rack::Auth generate a random username and password:

$ bin/rails secret # generate a secret
$ bin/rails credentials:edit

analytic:
  username: abc...
  password: def...

# config/initializers/analytic.rb

def same?(src, dst)
  # https://api.rubyonrails.org/classes/ActiveSupport/SecurityUtils.html
  ActiveSupport::SecurityUtils.secure_compare(src, dst)
end

Analytic.configure do |config|
  unless Rails.env.local?
    config.use Rack::Auth::Basic do |username, password|
      credentials = Rails.application.credentials.analytic
      same?(username, credentials.username) && same?(password, credentials.password)
    end
  end
end

Capturing Extra Parameters

By default Analytic tracks utm_source, utm_medium, utm_campaign, utm_content, utm_term, ref and source parameters for each request. This list can be customized using:

# config/initializer/analytic.rb
Analytic.configure do |config|
  config.params << :gclid # e.g. Google
  config.params << :msclkid # e.g. Bing
end

Changing the Time Zone

By default Analytic uses Time.zone. The time zone can be changed using:

# config/application.rb
class Application < Rails::Application
  config.time_zone = 'Canada/Pacific'
end

The time zone may also be specified for Analytic using any ActiveSupport::TimeZone:

# config/initializer/analytic.rb
Analytic.configure do |config|
  config.time_zone = Time.find_zone('Canada/Pacific')
end

Changing the Database

By default Analytic uses your apps main database. The database can be changed using:

# config/initializer/analytic.rb
Analytic.configure do |config|
  config.connects_to = { database: { writing: :primary, reading: :replica } }
end

Overriding IP Masking Rules

By default IP addresses are masked as follows:

• IPv4: limit to leading 24-bits (e.g. '255.255.255.255' becomes '255.255.255.0')
• IPv6: limit to leading 48-bits (e.g. 'ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff' becomes 'ffff:ffff:ffff:0000:0000:0000:0000:0000')

To override both an ip_v4_mask and ip_v6_mask are assignable:

Analytic.configure do |config|
  config.ip_v4_mask = 24 # nil skips masking
  config.ip_v6_mask = 48 # nil skips masking
