Configuration

Somewhere in your app, preferably at the root level, configure AmplifyCustomUi .

import React from "react";
import ReactDOM from "react-dom";

// amplify config
import Amplify from "aws-amplify";
import awsconfig from "./aws-exports";

// amplify-Custom-ui config
import * as aws_amplify_react from "aws-amplify-react";
import AmplifyCustomUi from "aws-amplify-react-custom-ui";

Amplify.configure(awsconfig);
AmplifyCustomUi.configure(aws_amplify_react);

ReactDOM.render(<App />, document.getElementById("root"));

Example

You can provide custom SignIn component by using , setSignIn:

import SignIn from "./SignIn";
import AmplifyCustomUi from "aws-amplify-react-custom-ui";
AmplifyCustomUi.setSignIn(SignIn);

params

withAuthenticator(Component, federated = null, theme = null) : component renders your App component after a successful user signed in, and it prevents non-sign-in uses to interact with your app. In this case, we need to display a sign-out button to trigger the related process.
configure(configuration) : configure the lib "aws-amplify-react-custom-ui" .
setSignIn(component) : to override the signIn page .
setForgotPassword(component) : to override the ForgotPassword page .
setConfirmSignUp(component) .
setVerifyContact(component) .
setSignUp(component) .
setRequireNewPassword(component) .
setConfirmSignIn(component) .
setTOTPSetup(component) .

the lib provide tow function authError , changeAuthState as props to the component , you need to use these function to notify that the authentication state had been changed , example .

App.js

import React, { Component } from "react";
import SignIn from "./SignIn";
import amplifyCustomUi from "aws-amplify-react-custom-ui";
