Thank you for putting great example.
@masayang
For me, AWS.config.credentials.identityId worked though AWS.config.credentials.data.identityId is undefined.
Thank you, works perfectly!
Does this create a new user pool user?
@RaphiStein No it doesn't. You will find this user in Federated Identity section on Cognito.
The only way to create FB user in cognito is by redirecting it to
https://your_domain.auth.us-east-1.amazoncognito.com/oauth2/authorize?redirect_uri=your_redirect_uri&response_type=token&client_id=xxxx& identity_provider=Facebook
Have a look at the @douglasgimli 's comment on amazon-archives/amazon-cognito-identity-js#608

Line 47 should be
console.log("Cognito Identity Id", AWS.config.credentials.data.identityId);
