Active Shipping

This library interfaces with the web services of various shipping carriers. The goal is to abstract the features that are most frequently used into a pleasant and consistent Ruby API. Active Shipping is an extension of Active Merchant, and as such, it borrows heavily from conventions used in the latter.

Active Shipping is currently being used and improved in a production environment for Shopify. Development is being done by the Shopify integrations team ([email protected]). Discussion is welcome in the Active Merchant Google Group.

Supported Shipping Carriers

Installation

gem install active_shipping

...or add it to your Gemfile.

Sample Usage

Compare rates from different carriers

require 'active_shipping'
include ActiveMerchant::Shipping

# Package up a poster and a Wii for your nephew.
packages = [
  Package.new(  100,                        # 100 grams
                [93,10],                    # 93 cm long, 10 cm diameter
                :cylinder => true),         # cylinders have different volume calculations

  Package.new(  (7.5 * 16),                 # 7.5 lbs, times 16 oz/lb.

                :units => :imperial)        # not grams, not centimetres

  puts "#{event.name} at #{event.location.city}, #{event.location.state} on #{event.time}. #{event.message}"

Running the tests

After installing dependencies with bundle install, you can run the unit tests with rake test:units and the remote tests with rake test:remote. The unit tests mock out requests and responses so that everything runs locally, while the remote tests actually hit the carrier servers. For the remote tests, you'll need valid test credentials for any carriers' tests you want to run. The credentials should go in ~/.active_merchant/fixtures.yml, and the format of that file can be seen in the included fixtures.yml.

Contributing

Yes, please! Take a look at the tests and the implementation of the Carrier class to see how the basics work. At some point soon there will be a carrier template generator along the lines of the gateway generator included in Active Merchant, but carrier.rb outlines most of what's necessary. The other main classes that would be good to familiarize yourself with are Location, Package, and Response.

For the features you add, you should have both unit tests and remote tests. It's probably best to start with the remote tests, and then log those requests and responses and use them as the mocks for the unit tests. You can see how this works with the USPS tests right now:

https://github.com/Shopify/active_shipping/blob/master/test/remote/usps_test.rb https://github.com/Shopify/active_shipping/blob/master/test/unit/carriers/usps_test.rb https://github.com/Shopify/active_shipping/tree/master/test/fixtures/xml/usps

To log requests and responses, just set the logger on your carrier class to some kind of Logger object:

USPS.logger = Logger.new($stdout)

(This logging functionality is provided by the PostsData module in the active_utils dependency.)

After you've pushed your well-tested changes to your github fork, make a pull request and we'll take it from there!
