The W3C have issued a Customer Experience Digital Layer Specification that allows sites to define a JavaScript object to make data accessible to third parties.
This plugin creates that object for an installation of WooCommerce, exposing various pieces of product and cart data to allow integration with third party code (for example, cart abandonment scripts).
It also exposes the logged in user’s name and email address, but only on their machine, so shouldn’t pose a privacy issue.
Tested on WooCommerce version 2.1.9
