Describe the feature

Currently we use an AwsCutstomResource to get cloudFrontDomainName attribute for a UserPoolDomain resource.

But actually CFn exposes the attribute natively. We can remove the unnecessary custom resource usage.

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-cognito-userpooldomain.html#aws-resource-cognito-userpooldomain-return-values

Use Case

To get a CloudFront domain for a user pool domain without using a custom resource. c.f. https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-pools-add-custom-domain.html

Proposed Solution

We can just replace it with a getAtt call.

  public get cloudFrontDomainName(): string {
    return resource.getAtt('CloudFrontDistribution').toString(),
  }
