A wrapper around @guardian/identity-auth which manages creating and configuring a IdentityAuth singleton to be used solely on www.theguardian.com by DCR, Frontend, and Commercial.
import { getIdentityAuth } from '@guardian/identity-auth-frontend';
const identityAuth = getIdentityAuth();
// Check if the user is logged in and return the current auth state
const authState = await identityAuth.isSignedInWithAuthState();
authState.isAuthenticated; // true or false
authState?.accessToken; // the user's access token object
authState?.idToken; // the user's id token object
// or boolean only
const isLoggedIn = await identityAuth.isSignedIn();
