Overview of this book

React sets the standard for building high-performance client-side web apps. Node.js is a scalable application server that is used in thousands of websites, while GraphQL is becoming the standard way for large websites to provide data and services to their users. Together, these technologies, when reinforced with the capabilities of TypeScript, provide a cutting-edge stack for complete web application development. This book takes a hands-on approach to implementing modern web technologies and the associated methodologies for building full-stack apps. You’ll begin by gaining a strong understanding of TypeScript and how to use it to build high-quality web apps. The chapters that follow delve into client-side development with React using the new Hooks API and Redux. Next, you’ll get to grips with server-side development with Express, including authentication with Redis-based sessions and accessing databases with TypeORM. The book will then show you how to use Apollo GraphQL to build web services for your full-stack app. Later, you’ll learn how to build GraphQL schemas and integrate them with React using Hooks. Finally, you’ll focus on how to deploy your application onto an NGINX server using the AWS cloud. By the end of this book, you’ll be able to build and deploy complete high-performance web applications using React, Node, and GraphQL.

Creating React client-side Hooks for querying Apollo GraphQL

In this section, we will finish off our application by connecting our React client to our GraphQL backend. We've come a long way and we're almost there.

In order to tie the two parts of our app together, we need to add CORS to our Express server. CORS stands for Cross-Origin Resource Sharing. It means that our server will be set up to allow a client domain that is not the same as its own domain.

In most server configurations of even modest complexity, the server that hosts the client-side application and the server that provides the API do not exist on the same domain. In general, you will have a proxy of some kind, for example, NGINX, that will accept calls coming from the browser. And that proxy will "redirect" calls as required. We will explain how reverse proxies work in more detail in Chapter 17, Deploying an Application to AWS.


A proxy is a stand-in for a service or some services...
