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 React Native project

In this section, we will cover the steps of how to implement Amplify UI components for a React Native app. Before we do that, we need to make sure we have installed the dependencies by entering the following command in the terminal:

yarn add aws-amplify aws-amplify-react-native

Once we have added the Amplify libraries to the Expo or React Native project, we would like to test the Authenticator UI library. There are two ways to do that: using the withAuthenticator Higher-Order Component (HOC) or using the actual Authenticator component. We picked the withAuthenticator component as an example. Let's add the following code to the existing App.tsx file:

import React from 'react';
import { withAuthenticator } from 'aws-amplify-react-native';
import Amplify from 'aws-amplify';
import awsExports from "./aws-exports";
const App = () => {
