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.

Chapter 5: Creating a Blog Post with Amplify GraphQL

In this chapter, we will be covering a very important part of creating an Amplify app; that is, letting users store and query their data with GraphQL. Back in the days before the GraphQL API existed, we had the RESTful API, which did not have a common standard for how to manipulate or query data. It was all up to the backend developers, which caused more delays during development. GraphQL removed the complexity of the API schema for frontend developers.

GraphQL standardizes the API schema, thus making it easy to define as a common practice and standard. Therefore, if you or your development team adopt GraphQL as your middle tier to interact between the frontend app and the backend business layers, it can speed up the development time and remove the dependency of waiting for both sides. The Amplify CLI can help you generate the GraphQL code based on the GraphQL data model schema that you define. We will learn how to do this by...
