Controllers are server-side scripts that handle storefront requests. Controllers manage the flow of data in your application, and create ViewModels to process each storefront request as a route and generate an appropriate response. For example, in a storefront application, clicking a category menu item or entering a search term triggers a controller that renders a page.
To support the Salesforce Payments functionality in SiteGenesis, you add or modify the following controllers to modify Checkout, Cart, Mini-Cart, and Product Detail Pages.
Controller Modifications
Cart.js–Controller that adds and removes products
and coupons in the cart. Also provides functions for the continue shopping button and minicart.paymentHelpers script from plugin_commercepayments
COBilling.js–Controller for the billing logic. It’s used by
both the single shipping and the multishipping functionality and is responsible for payment
method selection and entering a billing address.
COSsummary.js–Controller that implements the last step of
the checkout. A successful handling of billing address and payment method selection leads to
this controller. It provides the customer with a last overview of the basket before confirming
the final order creation.
