Vue Storefront and Headless API: Pagination Mapping for Large Datasets

Vue Storefront delegates data retrieval and pagination logic to the backend through its integration layer. When managing large datasets, the frontend typically passes offset and limit parameters to the API to bound the query and retrieve specific data segments.

A challenge arises when the backend API returns pagination metadata (such as total record counts or page indices) in a format that does not align with the standardized frontend state expectations. Because the integration layer must map these backend-specific responses to the VSF store, inconsistencies in API response structures can lead to incorrect pagination behavior in the UI.

Technical Constraints

• Dependence on backend indexing for query performance.
• Requirement for custom mapping logic within the integration layer to normalize diverse API responses.

What is the recommended approach for normalizing inconsistent pagination metadata across different headless providers within the Vue Storefront integration layer? How can the frontend state be synchronized when the backend does not provide a total count of records?
