    Study Notes

    Configured Commerce Admin API

    • Admin API requests have a 100 result limit per request
    • OData.NextLink is used to retrieve the next set of results
    • Admin API uses OData syntax, Storefront API uses RESTful JSON
    • Admin API supports child collections one level deep
    • Collections may be retrieved using the expand parameter or entity name
    • To update an Admin API entity, use the PATCH endpoint
    • Use JSON notation to set property and value when updating entities
    • The Insite.Data.Entities library contains entity models as simple objects
    • No business logic is present within the entity objects
    • Configured Commerce uses a UnitOfWork pattern for data providers
    • All entities are exposed via an OData RESTful service
    • Entities are defined as Partial classes, allowing for extensibility

    Entity Framework

    • Entity Framework is an open source, object-relational mapper included in the .NET Framework
    • Entity Framework is the default ORM used by Configured Commerce

    Goals and Best Practices

    • Entities in Configured Commerce should have minimal or no business logic
    • All business logic should be hosted in the service layer

    Basic Usage

    • Use the UnitOfWork object to access data
    • Obtain the appropriate Repository object from the UnitOfWork
    • Use the repository to access entities
    • The Get method can be used to retrieve a single entity by ID
    • The GetTable method will return an IQueryable collection of entities
    • The GetList method will fetch a list of entities immediately
    • Use the GetList method with caution, optimize your queries first
    • Lazy loading will automatically retrieve related entities and collections

    Performance

    • Consider performance implications when designing frontend elements
    • Home page loading times are critical, optimize images and data controls
    • Optimize image sizes to match display size
    • Use existing Javascript libraries instead of adding new ones
    • Caching is a crucial improvement strategy

    Caching Strategies

    • eTag caching uses server state to identify unchanged API requests
    • eTag caching can reduce server calculations and data marshalling

    Areas to Monitor

    • Monitor the retrieval of products, which are the most resource-intensive

    Performance Recommendations

    • Keep product list and search page entry limits low
    • Limit the number of entries in cross-sell, accessory, and related product widgets
    • Variant products with more than 40 variants may experience performance issues
    • Custom Properties are effective but can impact performance with large data volumes

    Data Size and Limits

    • These data size targets are intended to represent reasonable loads
