In the tutorial - https://medium.com/@nickwang_58849/i-got-the-following-error-after-following-the-steps-82757cfaf9f0, it uses amplify-authenticator of npm package @aws-amplify/auth to login and register.

auth.component.html has just one line,

<amplify-authenticator></amplify-authenticator>

auth.component.ts

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-auth',
  templateUrl: './auth.component.html',
  styleUrls: ['./auth.component.css']
})
export class AuthComponent implements OnInit {
  constructor() { }
  ngOnInit() {
  }
}

However, I will need to have a customized login (will need to add some required attributes when registering. And need to style the login/register controls). How to do it?

Is there any example of user write the login UI and just call the authentication (by amplify?) to log in cognito?

If you're using the latest Amplify modules (April 2020) you can customize the look and feel using CSS:

:root {
  --amplify-primary-color: #008000;
  --amplify-primary-tint: #0000FF; 
  --amplify-primary-shade: #008000;
}

and you can customize the text:

<AmplifySignIn headerText="My Custom Sign In Header" slot="sign-in" />
<AmplifySignUp headerText="My Customer Sign Up Header" slot="sign-up" />
