Analytics.js-Rails

This gem packages a self-hosted copy of Analytics.js, a wrapper for web analytics services, for use with the Ruby on Rails 3.1+ asset pipeline.

The unfortunate truch: Analytics Service A is good at X, bad at Y, Analytics Service B is good at Y, bad at X and Z. Or maybe Marketing likes Service A, but Engineering needs Service B. Whatever. Analytics.js offers one common interface to standardize and modularize analytics setup across services - now easily in rails.

Installation

Add this line to your application's Gemfile:

gem 'analytics-js-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install analytics-js-rails

Usage

Render the loader partial on all pages where you want Analytics.js to load. Typically this is done in application.html.erb, immediately after the opening tag. For example:

<%= render 'analytics-js/loader', 
  user_identifier: current_user.id, 
  providers: { 
    'Google Analytics' => 'google_analytics_key',
    'KISSmetrics' => 'kissmetrics_key'
} %>

Of course, keys should probably be stored in config files, not hard coded.

Make sure that you root :to => "controller#action" in config/routes.rb.

Add to your config/environments/production.rb:

config.assets.precompile += %w( analytics.js )

You can now use Analytics.js in your app.

Version
