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.

Comparing and contrasting the class way versus the Hooks way

In this section, we will discuss some of the differences between the class way and the Hooks way of writing code in React. We will see why the React team decided Hooks was the way forward. Learning these details will give us confidence in using Hooks in our own code.

Code reuse

If you look at the class-based lifecycle methods, not only are there many to remember and understand, you can also see that for each class component you would have a pretty much unique implementation of lifecycle functions. This makes code reuse difficult to do with classes. With Hooks, we also have many different built-in Hooks we can use and need to know. However, they are not component specific and can be reused for different components at will. This is the key motivator for using Hooks. Code reuse is much easier because the Hooks are not tied to any specific class. Each Hook is focused on providing a specific capability or functionality,...
