We’re grouping all the basket-related logic together in BasketService. You may have noticed the
reference to ngCookies (when creating the app module) and the extra script file reference (in
index.blade.php). These allow us to use AngularJS’s cookies module; for storing the basket items.
The getProducts() method returns the products. We need to store them as a serialised JSON array,
so when we initially retrieve them; we parse them (with a default value of ”[]”). The add() and
remove() methods create and destroy special item objects. After each basket item operation; we
need to persist the products array back to $cookies.
The update() method works out the total cost of each item; by taking into account the original price
and the updated quantity. It also rounds this value to avoid floating-point calculation irregularities.
There’s also a store() method which persists the products to $cookies, and a clear() method which
removes all products.
The HTML, compatible with all this, is:
