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.

Understanding session state

In this section, we'll learn what session state is and why it's necessary. We'll revisit some of the concepts of how the web works and understand why we need session state.

The web is actually not one thing. It is a collection of many technologies. The core of the web is the HTTP protocol. This is the communication protocol that allows the web to work over the internet. A protocol is simply an agreed-upon set of rules for communication. This sounds somewhat straightforward, and for some things, it can be. However, for our application, it's a little more complicated.

The HTTP protocol is a connectionless protocol. This means that HTTP connections are made only at the time a request is made and then released. So, a connection is not maintained, even if a user is actively using a website for hours. This makes HTTP more scalable. However, this also means certain features that larger websites need are more difficult to create when...
