Import

Each screen has its own set of hooks and methods. The SDK supports partial import and root import for each screen.
  • Using partial import allows you include only the code you need for your specific use case.
  • Using root import allows you to load all screens from a single bundle useful when you want a unified build to handle all possible screens.
Import Example
// root import
import { useMfaCountryCodes } from '@auth0/auth0-acul-react';

// partial import
import {
  useMfaCountryCodes,
  // Context hooks
  useUser,
  useTenant,
  useBranding,
  useClient,
  useOrganization,
  usePrompt,
  useScreen,
  useTransaction,
  useUntrustedData,
  // Common hooks
  useCurrentScreen,
  useAuth0Themes,
  useErrors,
  // Utility hooks
  useChangeLanguage,
  // Methods
  goBack,
  selectCountryCode,
} from "@auth0/auth0-acul-react/mfa-country-codes";

function MfaCountryCodesScreen() {
  const { selectCountryCode } = useMfaCountryCodes();
  return (
    <button onClick={() => selectCountryCode({ country_code: 'US', phone_prefix: '+1' })}>
      Select +1 (US)
    </button>
  );
}
