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.

Learning about spread, destructuring, and rest

In ES6+, there are new methods for handling object copying and displaying variables and parameters. These capabilities go a long way in making JavaScript code both shorter and easier to read. These features have become standard practice in modern JavaScript, so it is important that we know about them and use them properly.

Spread, Object.assign, and Array.concat

The spread, Object.assign, and Array.concat JavaScript features are fairly similar. Basically, you are appending multiple objects or arrays together into one object or array. However, strictly speaking, there are some differences.

In the case of objects, there are two ways of merging or concatenating objects:

  • Spread—for example, { … obja, …objb }: You are creating a non-modified copy of these two objects and then creating a brand-new object. Note that spread can handle more than just two objects.
  • Object.assign(obja, objb): You are...
