Checks
You should remove all persisted and in-memory user content after a logout. You should logout from every external services silently.
If my project uses react-apollo
the cache is cleared with client.resetStore​
If my project uses redux
there is a LOGOUT or RESET_CUSTOMER_DATA action that replaces the user reducers' states with the initial states
If my project uses React-Native AsyncStorage
the cache is cleared with AsyncStorage.clear, or AsyncStorage.multiRemove if you need to target only some keys.
Errors should be caught and handled
Good examples
// pseudo code
const logout = async () => {
  try {
    await fetch('ZENDESK_LOGOUT_URL', { method: 'GET' });
    await firebase.auth().signOut();
    await AsyncStorage.clear();
    ReduxStore.dispatch(resetCustomerData());
    apolloClient.resetStore();
    Navigation.navigate('login');
  } catch (e) {
    HandleErrorService.handleError(e);
    // eventually show an error or retry
  }
}
Bad examples
Example 1
Without cleaning the user data, you will have state and data inconsistencies with the new user.
// pseudo code
const logout = async () => {
  Navigation.navigate('login');
}
Example 2
Without the try catch, the app will crash if the user has no connection, or if another error happens.
// pseudo code
const logout = async () => {
    await fetch('ZENDESK_LOGOUT_URL', { method: 'GET' });
    await firebase.auth().signOut();
    await AsyncStorage.clear();
    ReduxStore.dispatch(resetCustomerData());
    apolloClient.resetStore();
    Navigation.navigate('login');
}
