Plug 'n' Play: Cart-Agnostic Design Principles for Joomla! eCommerce - Donald Champion

Cart-agnostic Design Principles refer to a specific methodology for planning and developing custom code and extensions. This methodology allows a core body of code to support multiple Joomla! eCommerce extensions like VirtueMart, redSHOP, HikaShop and more. By following this approach, developers can design solutions that are more easily extended to support additional shopping carts, as well as being easier to maintain and upgrade. Even if you only write solutions to support one shopping cart at a time, you can still benefit from using these design principles. Donald Champion will cover the initial planning process, understanding similar data structures between popular carts, and how to evaluate the pros and cons of different abstraction methods for your project.Donald Champion, CTO of Polished Geek, is the designer of JoomLister, the only native eBay listing component for Joomla! eCommerce that is also an eBay Certified Compatible Application. Donald designed JoomLister from the ground up using a cart-agnostic approach, so adding a new shopping cart only requires changes to five files or less. He'll use some real life examples from the JoomLister extension to illustrate key concepts during this engaging developer presentation.
