childrenEntitiesSelector

childrenEntitiesSelector is a function which creates a predefined relationship selector factory. Its goal is to simply the process of creating relationship selectors with childrenEntities.

declare function childrenEntitiesSelector(
  selector,
  keyId,
  keyValue,
);

Its parameters are the same as childrenEntities has, but without relationships.

const company = rootEntitySelector(
  selectCompanyState,
);
const companyStaff = childrenEntitiesSelector(
  selectUserState,
  'companyId',
  'staff',
);

// later.
const company1 = company(
  selectUserState(),
);

// the same as.
const company2 = rootEntity(
  selectCompanyState,
  childrenEntities(
    selectUserState,
    'companyId',
    'staff',
  ),
);
