Rapid Application Development with AWS Amplify

By: Adrian Leung

Overview of this book

AWS Amplify is a modern toolkit that includes a command line interface (CLI); libraries for JS, iOS, and Android programming; UI component libraries for frameworks like React, Angular, and Vue.js for web development, and React Native and Flutter for mobile development. You'll begin by learning how to build AWS Amplify solutions with React and React Native with TypeScript from scratch, along with integrating it with existing solutions. This book will show you the fastest way to build a production-ready minimum viable product (MVP) within days instead of years. You'll also discover how to increase development speed without compromising on quality by adopting behavior-driven development (BDD) and Cypress for end-to-end test automation, as well as the Amplify build pipeline (DevOps or CI/CD pipeline) to ensure optimal quality throughout continuous test automation and continuous delivery. As you advance, you'll work with React to determine how to build progressive web apps (PWAs) with Amplify and React Native for cross-platform mobile apps. In addition to this, you'll find out how to set up a custom domain name for your new website and set up the AWS Amplify Admin UI for managing the content of your app effectively. By the end of this AWS book, you'll be able to build a full-stack AWS Amplify solution all by yourself.

Adding Amplify UI components to a ReactJS project

Let's open the App.tsx file of our ReactJS project. We will add the following TypeScript code to the app:

  1. As usual, import the essential React and Amplify libraries as well as the App.css file:
    import React from 'react';
    import './App.css';
    import Amplify from 'aws-amplify';
  2. Import the AmplifyAuthenticator and AmplifySignOut UI components. We will integrate the sign in, sign up, and sign out UI components first:
    import { AmplifyAuthenticator, AmplifySignOut } from '@aws-amplify/ui-react';
    import { AuthState, onAuthUIStateChange } from '@aws-amplify/ui-components';
  3. Import the AWS setting file. Please make sure that you don't commit the aws-export.js or .ts setting files to the Git repository because the AWS console will figure it out itself:
    import awsExports from "./aws-exports";
    const App = () => {
  4. We will create...
