Question

React Native

How to download all the necessary data before authorization and after authorization?
now I load the data in each screen (componentDidmount) and save it in redux store or asyncstorage

Answer 1

The data necessary for initialization can be loaded in an async action:

const store = configureStore();

store.dispatch(init());

const App: React.FC = () => (
  <Provider store={store}>
    <Navigation />
  </Provider>
);
