    - Creating a custom Store using React
      You can create a React single page application Store using the HCL Commerce Store SDK that is provided for pages and react components. The Store SDK allows your front end developers to quickly develop and deploy a Store while focusing on creating the best user experience possible.
      - React Store architecture
        The React Store architecture is based on a Single Page Application (SPA) model whereby the browser loads the React JavaScript as an application, executes an HTTP request to retrieve data and renders the storefront UI. The model is a client-centric headless Store model that makes API calls to scalable services provided by the HCL Commerce Transaction server and HCL Commerce Search server.
      - Publishing a React Store
        The site administrator must first publish the React Store data model by using the Gradle script and the starterstores/EmeraldDataTemplate.zip template.
      - Downloading the HCL Commerce Store SDK
        HCL Commerce provides a standalone Store SDK with Reference Store applications that is based on the Node.js react-app. The Store SDK is completely independent of the HCL Commerce toolkit.
      - Store SDK and application configurations
        The HCL Commerce Store SDK provides a set of foundational React components for interacting with HCL Commerce business logic that can be used as the basis for creating and managing your custom Store and allows front end developers to focus on customizing and replacing the display and view aspects of the store. All aspects of the React application, including the foundation, are customizable by front end developers and are provided as references to interact with HCL Commerce REST APIs and session management.
      - Store SDK structure
        The Store SDK contains all the components, widgets, UI forms, and so on, that are required to start developing your custom React store.
      - Customizing your home page
        When the React Store application homepage is launched, the React Router considers the relative path and loads the respective page component configured for that path.
      - Using e-Marketing spots
        The React Store single page application (SPA) contains e-Marketing spots which reserve areas on store pages for displaying personalized marketing content from activities. e-Marketing spots on pages allow business users to change the content easily.
      - Search engine optimization

      - Managing digital assets
        HCL Commerce does not provide any tools to manage digital assets for the React Stores and recommends that you use a third party digital asset management tool such as HCL Digital Experience. As such, catalog and marketing assets, images and attachments should simply be managed as fully qualified URLs with Management Center or through the data load processes.
      - Managing content in HCL Digital Experience
        HCL Commerce integration with HCL Digital Experience allows digital assets managed within HCL Digital Experience to be utilized anywhere within the HCL Commerce storefront..

        In the B2B business model, each company that purchases from your store must have one or more registered users who are assigned the Buyer Administrator role. You can also assign the Buyer Approver role to users. The B2B Reference Store application (Sapphire) provides a link to the Management Center for Buyer Administrators and Buyer Approvers to complete the tasks that are assigned to them.
      - Building and deploying the store
        The custom React Store application is built as a React SPA static model and can be deployed to any web server of your choice. The Store SDK build process supports the building of multiple apps.

These widgets enable the shoppers to get a quick overview of the desired products, without searching them manually and thus help in enhacing their shopping experience.
  - Presentation layer
    HCL Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern. The view layer is in charge of retrieving data from the database through the use of data beans and formatting it to meet the display requirements. The view layers determines whether the request is sent to a browser or streamed out as XML. JSP files present a clean separation between data content and presentation.
  - Controller layer
    The Controller layer is the conductor of operations for a request. It controls the transaction scope and manages the session related information for the request. The controller first dispatches to a command and then calls the appropriate view processing logic to render the response.
  - Business logic layer
    The business logic layer is the business components that provide OAGIS services to return data or start business processes. The presentation layer uses these OAGIS services to display data, or to invoke a business process. The business logic provides data required by the presentation layer. The business logic layer exists because more than just fetching and updating data is required by an application; there is also additional business logic independent of the presentation layer.
  - Persistence layer
    The interaction between the business objects and persistence layer is isolated in an object called the Business Object Mediator. Business object document (BOD) commands interact with the Business Object Mediator to handle the interaction with the logical objects and how they are persisted.
  - Business model information model
    A business model, a representation of the business processes used throughout the site, provides a sample commerce solution which includes an organization structure, default user roles and access control policies, one or more starter stores, administration tools, and business processes that demonstrate best practices. A business model can be customized to support business requirements and scenarios. HCL Commerce provides sample business models that show some common commerce solutions. These business models are created by setting up an organization hierarchy structure, access control policies, stores, and contracts that help satisfy the necessary business requirements.
  - Business models
    Before starting to develop your site with HCL Commerce, you need to determine the business model supported by HCL Commerce that best represents the purpose of your site. Usually sites created with HCL Commerce will be implemented based on of one of these business models.
  - Store data information model
    Store data is the information that is loaded into the Transaction server database, which allows your store to function. The URL Registry Entries and View Registry Entries packages are included in the diagram, but they are not database assets. These entries are presentation configuration (that is, struts actions and forwards) that must be deployed. URL registry entries are shown in the diagram to illustrate the entire store data information model. To operate properly, a store must have the data in place to support all customer activities. For example, in order for a customer to make a purchase, your store must contain a catalog of goods for sale (catalog data), the data associated with processing orders (tax and shipping data), and the inventory to fulfill the request (inventory and fulfillment data).
  - Customizing HCL Commerce
    You can extend the HCL Commerce product to fit your business needs. This topic describes the prerequisite skills and required knowledge that you need to customize business logic. After you have the required knowledge, use HCL Commerce Developer to take tutorials that guide you step-by-step through various customization scenarios.

  - GraphQL for HCL Commerce
    The GraphQL markup language is available for any API. It is a server-side interpreter for processing queries using a data type system you design. With GraphQL, your data and code are independent of any database or storage system.
  - Representational State Transfer (REST) services
    HCL Commerce uses Representational State Transfer (REST) services to provide a framework that can be used to develop RESTful applications on several platforms. These platforms can include web, mobile, kiosks, and social applications.
  - Web services

Page Composer for React store

You can create a React Store using the HCL Commerce Store SDK that is provided for pages and react components. The Store SDK allows your front end developers to quickly develop and deploy a Store specially Sapphire and Emerald while focusing on creating the best user experience possible.

You can visit the Management Center for HCL Commerce to learn more about how Page Composer works with Emerald and Sapphire store. The related documentation can be found at Page Composer tool.

The Page Composer-enabled pages introduced in Version 9.1.7.0 have layouts and the widgets that can be managed through Management Center. These Page Composer enabled pages have a provision for some predefined layouts as shown in the following image that depicts the templates for HCL Commerce Versions 9.1.10.0.

Note: The initial HCL Commerce Versions 9.1.7.0 and 9.1.8.0 widgets, only have Home Page, B2B Product Page, product Page, Category Landing Page and Product Listing Page widgets.

HCL Commerce Version 9.1.9.0 or later Widgets such as Cart Page, Checkout Page, Order Confirmation page, and Bundle Page widget are added, in addition to the existing 9.1.8.0 Version widgets.

HCL Commerce Version 9.1.10.0 or later For HCL Commerce Versions 9.1.10.0 and onwards, a new Kit Page widget is added.

Note: The managed portions managed by the Page Composer tool for each layout are highlighted in light blue color. The header and footer in the Emerald store are not managed by the Page Composer tool.

Refer to the topic Page Composer overview to explore the Page Composer layouts.

The following is the default Category Landing Page layout, which can be similar to the Emerald Store image shown below. Here, the first slot consists of an e-marketing-spot widget and the second slot has the child-category-grid widget.

Note: In HCL Commerce Version 9.1.6.0., this Category Landing page was rendered using src/components/layouts/category-page/CategoryPageLayout.tsx component. The rendered layout obtained as the output was similar to the OOTB layouts. However, in this file, the slots were hard-coded with the CategoryRecommendationLayout and ChildPimCategoriesLayout components, invoked from the src/components/pages-seo/category/Category.tsx component that was resolved by the SEO reducer.
