Middleware handle interaction across features or services.

Apply sort order

.withDelegateMiddleware(using: store.dispatch)
.withDelegateMiddleware(.applySelection(dispatchToPrevious: store.dispatch))
.withDelegateMiddleware(.applySelectionOnSelect(dispatchToPrevious: store.dispatch))

Middleware to delegate (pass back) the new SortOrder selection to the previous feature. This delegate middleware pattern is used by all selection features.

This middleware must be added to the builder when building this feature.

Handles the following actions:

SelectionStateAction.applySelection: This action dispatches a SortSelectionAction with state.selected to the dispatch function injected into the builder (usually the previous feature's store.dispatch). The dispatch function acts as a delegate so this means the apply action and data is sent to the previous feature.
