Shopunity is an Extension manager with dependency support. You may have heard of Composer for Php and NPM for NodeJS. Well Shopunity is very much the same, only for Opencart.
Customers use Shopunity to install and update their extensions with a click of a button, just like you would install, update or delete a plugin in wordpress.
Developers use Shopunity for repid development of their extensions. So now a developer can specify a dependency in a json file, and it will be uploaded and installed automaticly in the backend. Pretty neat, eh?
