relatedEntitySelector

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

declare function relatedEntitySelector(
  entityStateSelector,
  keyId,
  keyValue,
);

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

const user = rootEntitySelector(
  selectUserState,
);
const userCompany = relatedEntitySelector(
  selectCompanyState,
  'companyId',
  'company',
);

// later.
const user1 = user(
  userCompany(),
);

// the same as.
const user2 = rootEntity(
  userSelector,
  relatedEntity(
    companySelector,
    'companyId',
    'company',
  ),
);
