How to use the @loadable/component.loadableReady function in @loadable/component

// Should allow preloading
    LazyDefaultLibrary.preload();

    // Should allow force loading
    LazyDefaultLibrary.load().then(Component => {
        ;
    });
}

// loadableReady
{
    // Should allow passing callback argument
    loadableReady(() => {});

    // Should return a promise
    loadableReady().then(() => {});

    // Should allow passing options with namespace
    loadableReady(() => {}, { namespace: 'foo' });
}

const initialState = (window as any).__INITIAL_STATE__;
  const store = createStore(initialState);
  const App = () => {
    return (
      
        
          
        
      
    );
  };
  return ;
}

// 开始渲染之前加载所需的组件
loadableReady().then(() => {
  ReactDOM.hydrate(createApp(Root), document.getElementById("app"));
});

// 热更新
if (module.hot) {
  module.hot.accept("./App", () => {
    const NewApp = require("./App").default;
    ReactDOM.hydrate(createApp(NewApp), document.getElementById("app"));
  });
}
