Arctic vendor

This gem is the backbone used for communication from Vendors to the Core API.

Usage

Install the gem:

gem 'arctic-vendor'

Then in your code:

require 'bundler/setup'
require 'arctic/vendor'

module Arctic
  module Vendor
    module Dandomain # <-- Change this depending on the vendor you're using
      def collect_products
        Arctic::Vendor.collect_products do |shop|
          # Retrieve products from the shop and return them to the block
        end
      end
      module_function :collect_products

      def distribute_products
        Arctic::Vendor.distribute_products do |shop, products|
          # Send the products to the shop and return the products to the block
        end
      end
      module_function :distribute_products
    end
  end
end

Then in your Rakefile:

require_relative "./path/to/your/lib"

desc "Sync"
task :sync do
  # You can skip either of these if the vendor doesn't support either pulling or
  # pushing products and orders.
  Arctic::Vendor::Dandomain.collect_products
  Arctic::Vendor::Dandomain.distribute_products
end

Logger

To change the logging mechanism simply override the standard STDOUT logging.

require 'arctic/vendor'
logger = Logger.new 'file.log'
logger.formatter = Ruby::JSONFormatter::Base.new \
  ENV.fetch('HOST'),
  source: :your_application
Arctic.logger = logger

Validation API

Each vendor should implement a validation API, which the Core API can use to ensure that a product is valid for the given vendor before sending the product to the vendor, and to allow the user to quickly see if his changes to the product has made it invalid for this vendor.

Your implementation should have a validation class taking two arguments, a product json object and an options hash.

You should then add this to your code somewhere:

Arctic.validator_class = 'YourValidatorClass'

And then you should ensure that you expose the validation API somewhere publically available. This is most easily done using a config.ru file with the rackup command.

# config.ru
run Arctic::ValidationApi

Testing

Run all the tests:

rake test
