URB <img src=“https://secure.travis-ci.org/archan937/urb.png”/> <img src=“https://codeclimate.com/github/archan937/urb.png”/>¶ ↑

Shorten URLs in your Rack / Rails app.

Installation¶ ↑

Using Bundler¶ ↑

Add URB in Gemfile as a gem dependency:

gem "urb"

Run the following in your console to install with Bundler:

$ bundle install

Usage¶ ↑

Include urb.js¶ ↑

Invoke the view helper method urb within your template:

<!DOCTYPE html>
<html>
  <head>
    <title>Killer App</title>
    <%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
    <%= javascript_include_tag "application", "data-turbolinks-track" => true %>
    <%= csrf_meta_tags %>
    <%= urb %>
  </head>

Start opening URLs¶ ↑

Click on links within your webpage or call the Javascript function URB.open().

<script>
  URB.open('/?p=today&f[]=paulengel&f[]=archan937&f[]=URB&f[]=demo&f[]=Rails&f[]=Long%20URL&f[]=foo&f[]=bar&f[]=baz&f[]=Ownage&f[]=AwesomeStuff&bd[]=Paul.Engel&foobarbaz_id[]=3&foobarbaz_id[]=1&foobarbaz_id[]=4&foobarbaz_id[]=5&foobarbaz_id[]=6&foobarbaz_id[]=7&foobarbaz_id[]=67&foobarbaz_id[]=108&foobarbaz_id[]=66&foobarbaz_id[]=65&foobarbaz_id[]=118&foobarbaz_id[]=68&foobarbaz_id[]=8&foobarbaz_id[]=128&foobarbaz_id[]=79&foobarbaz_id[]=78&foobarbaz_id[]=111&foobarbaz_id[]=9&foobarbaz_id[]=10&foobarbaz_id[]=129&foobarbaz_id[]=11&foobarbaz_id[]=124&foobarbaz_id[]=12&foobarbaz_id[]=130&foobarbaz_id[]=13&foobarbaz_id[]=121&foobarbaz_id[]=14&foobarbaz_id[]=77&foobarbaz_id[]=80&foobarbaz_id[]=15&foobarbaz_id[]=69&foobarbaz_id[]=16&foobarbaz_id[]=17&foobarbaz_id[]=131&foobarbaz_id[]=18&foobarbaz_id[]=117&foobarbaz_id[]=19&foobarbaz_id[]=81&foobarbaz_id[]=82&foobarbaz_id[]=20&foobarbaz_id[]=21&foobarbaz_id[]=96&foobarbaz_id[]=97&foobarbaz_id[]=98&foobarbaz_id[]=99&foobarbaz_id[]=112&foobarbaz_id[]=64&foobarbaz_id[]=63&foobarbaz_id[]=62&foobarbaz_id[]=22&foobarbaz_id[]=23&foobarbaz_id[]=120&foobarbaz_id[]=24&foobarbaz_id[]=87&foobarbaz_id[]=88&foobarbaz_id[]=61&foobarbaz_id[]=60&foobarbaz_id[]=70&foobarbaz_id[]=71&foobarbaz_id[]=100&foobarbaz_id[]=101&foobarbaz_id[]=25&foobarbaz_id[]=26&foobarbaz_id[]=132&foobarbaz_id[]=73&foobarbaz_id[]=72&foobarbaz_id[]=56&foobarbaz_id[]=55&foobarbaz_id[]=74&foobarbaz_id[]=75&foobarbaz_id[]=133&foobarbaz_id[]=83&foobarbaz_id[]=84&foobarbaz_id[]=27&foobarbaz_id[]=107&foobarbaz_id[]=28&foobarbaz_id[]=134&foobarbaz_id[]=135&foobarbaz_id[]=136&foobarbaz_id[]=29&foobarbaz_id[]=119&foobarbaz_id[]=113&foobarbaz_id[]=105&foobarbaz_id[]=104&foobarbaz_id[]=114&foobarbaz_id[]=89&foobarbaz_id[]=103&foobarbaz_id[]=30&foobarbaz_id[]=137&foobarbaz_id[]=76&foobarbaz_id[]=90&foobarbaz_id[]=93&foobarbaz_id[]=92&foobarbaz_id[]=109&foobarbaz_id[]=110&foobarbaz_id[]=139&foobarbaz_id[]=31&foobarbaz_id[]=32&foobarbaz_id[]=140&foobarbaz_id[]=33&foobarbaz_id[]=123&foobarbaz_id[]=34&foobarbaz_id[]=141&foobarbaz_id[]=35&foobarbaz_id[]=115&foobarbaz_id[]=36&foobarbaz_id[]=142&foobarbaz_id[]=86&foobarbaz_id[]=85&foobarbaz_id[]=94&foobarbaz_id[]=95&foobarbaz_id[]=37&foobarbaz_id[]=38&foobarbaz_id[]=40&foobarbaz_id[]=39&foobarbaz_id[]=41&foobarbaz_id[]=42&foobarbaz_id[]=43&foobarbaz_id[]=44&foobarbaz_id[]=45&foobarbaz_id[]=102&foobarbaz_id[]=57&foobarbaz_id[]=58&foobarbaz_id[]=46&foobarbaz_id[]=47&foobarbaz_id[]=48&foobarbaz_id[]=49&foobarbaz_id[]=50&foobarbaz_id[]=59&foobarbaz_id[]=51&foobarbaz_id[]=122&foobarbaz_id[]=52&foobarbaz_id[]=53&foobarbaz_id[]=116&foobarbaz_id[]=54&foobarbaz_id[]=106&foobarbaz_id[]=2&foobarbaz_id[]=91&foobarbaz_id[]=138');
</script>

URB will automatically shorten the URL when it refers to the application itself and exceeds URB::MAXLENGTH (which is 2000 characters).

URL storage¶ ↑

The shortened URLs are stored using the Moneta gem. At default, they will be stored in memory.

To store them within a database, configure URB with URB.configure (shortcut: URB) and the arguments will be forwarded to the Moneta constructor:

(e.g. in config/initializers/u.rb)

URB.config :ActiveRecord, :table => "urls", :connection => {:adapter => "mysql2", :database => "my_awesome_app", :user => "someone", :password => "letmypass"}

or probably

(e.g. in config/initializers/u.rb)

URB :ActiveRecord, :table => "urls", :connection => ActiveRecord::Base.connection.instance_variable_get(:@config)

The corresponding migration file should look like:

class CreateUrls < ActiveRecord::Migration
  def change
    create_table :urls do |t|
      t.text :k
      t.text :v
      t.timestamps
    end
  end
end

You can try this out in the provided demo application. Do not forget to uncomment the last line in config/initializers/u.rb.

Console and demo Rails app¶ ↑

The URB repository is provided with a console which you can start with script/console.

Also, you can run the provided Rails 4 demo application to try out URB in your browser.

Testing¶ ↑

Run the following command for testing:

$ rake
