useRelationshipsIds

The useRelationshipsIds hook is used to retrieve the Ids of all the named Relationships objects present in the current Provider component context.

useRelationshipsIds(): Ids
returnsIds

A list of the Ids in the context.

Example

This example adds two named Relationships objects to a Provider context and an inner component accesses their Ids.

const App = ({store}) => {
  const store1 = useCreateStore(createStore);
  const relationships1 = useCreateRelationships(
    store1,
    createRelationships,
  );
  const store2 = useCreateStore(createStore);
  const relationships2 = useCreateRelationships(
    store2,
    createRelationships,
  );
  return (
    <Provider relationshipsById={{relationships1, relationships2}}>
      <Pane />
    </Provider>
  );
};
const Pane = () => <span>{JSON.stringify(useRelationshipsIds())}</span>;

const app = document.createElement('div');
ReactDOMClient.createRoot(app).render(<App />);
console.log(app.innerHTML);
// -> '<span>["relationships1","relationships2"]</span>'
