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.

Exploring TypeScript types

In this section, we'll look at some of the core types available in TypeScript. Using these types will give you error checking and compiler warnings that can help improve your code. They will also provide information about your intent to other developers that may be on your team. So, let's continue and see how these types work.

The any type

The any type is a dynamic type that can be set to any other type. If you declare a variable to be of the any type, this means that you can set it to anything and reset it to anything else later as well. It is in effect no type because the compiler will not check it on your behalf. This is the key fact to remember about any – the compiler will not intercede and warn you of issues at development time. Therefore, if possible, using the any type should be avoided. It may seem weird that a language that was built to be statically typed would have such a feature, but it is a necessity under certain circumstances...
