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.

What are types?

A type is a reusable set of rules. A type may include properties and functions (capabilities). It can also be shared and reused over and over again. When you reuse a type, you are creating an instance of it. This means that you are creating an example of your type that has specific values for properties. In TypeScript, as the name implies, types are very important. They're the main reason why the language was created in the first place. Let's take a look at how types work in TypeScript.

How do types work?

As mentioned previously, JavaScript does have types. Number, string, Boolean, array, and so on are all types in JavaScript. However, those types are not explicitly set during declaration; they are only inferred at runtime. In TypeScript, types are normally set during declaration. It is possible to allow the compiler to infer your type. However, the type the compiler chooses may not be the one you desire since it isn't always obvious. In addition...
