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.

Now that we have created the user successfully, we can go to the AWS Cognito console to check out the user that has been created in the user pool:

As you can see, with just a few lines of code, we have integrated the entire authentication flow. Now, let's try to sign in with one of the users that we have created:

  1. We will sign in with the last user that we have created. If you've forgotten the password, you can click on the Forgot Password button to retrieve it. We will show you how to do this because it is a very important self-help feature that most users will use when they forget their password. Let's press the Forgot Password button:

  2. Enter the username that you forgot the password for and then press the SEND button:
