Sign Up User With Email And Password

AWS Amplify Auth offers both federated and username/password based authentication. Though the docs aren't clear, the required username parameter can be used as the email field with the signUp API.

import { Auth } from 'aws-amplify';

async function signUp({ email, password }) {
  try {
    const user = await Auth.signUp({
      username: email,
      password,
      attributes: {},
    });
    console.log({ user });
  } catch (error) {
    console.log('error signing up:', error);
  }
}

Once the user has entered an email and password into the Sign Up form, those values can be passed to this signUp function. The email value is passed as the username and the password goes in as is.

Amplify Auth will interpret the username as an email and register it as the contact email for this user.
