Storefront Controller

Controller

• Each controller action requires a #Route attribute.
• The name of the route should start with "frontend".
• Each route should define the corresponding HTTP Method (GET, POST, DELETE, PATCH).
• The function name should be concise.
• Each function should define a return type hint.
• A route should have a single purpose.
• Use Symfony flash bags for error reporting.
• Each storefront functionality has to be available inside the Store API too.
• A Storefront controller should never contain business logic.
• The class requires the attribute: #[Route(defaults: ['_routeScope' => ['storefront']])].
• Depending services have to be injected over the class constructor.
• Depending services have to be defined in the DI-Container service definition.
• Depending services have to be assigned to a private class property.
• A Storefront controller has to extend the \Shopware\Storefront\Controller\StorefrontController.

Read operations inside Storefront controllers

• A Storefront controller should never use a repository directly. The data should be fetched over a route or page loader.
• Routes that load a full Storefront page should use a page loader class to load all corresponding data.
• Pages that contain data that are the same for all customers should have the _httpCache annotation.

Write operations inside Storefront controllers

• Write operations should create their response with the createActionResponse function to allow different forwards and redirects.
• Each write operation has to call a corresponding Store API route.
