Middleware

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.

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.
