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
