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.

Chapter 1: Understanding TypeScript

JavaScript is an enormously popular and powerful language. According to GitHub, it is the most popular language in the world (yes, used even more than Python), and the new features in ES6+ continue to add useful capabilities. However, for large application development, its feature set is considered to be incomplete. This is why TypeScript was created.

In this chapter, we'll learn about the TypeScript language, why it was created, and what value it provides to JavaScript developers. We'll learn about the design philosophy Microsoft used in creating TypeScript and why these design decisions added important support in the language for large application development.

We'll also see how TypeScript enhances and improves upon JavaScript. We'll compare and contrast the JavaScript way of writing code with TypeScript. TypeScript has a wealth of cutting-edge features to benefit developers. Chief among them are static typing and Object-Oriented Programming (OOP) capabilities. These features can make for code that is higher quality and easier to maintain.

By the end of this chapter, you will understand some of the limitations of JavaScript that make it difficult to use in large projects. You will also understand how TypeScript fills in some of those gaps and makes writing large, complex applications easier and less prone to error.

In this chapter, we're going to cover the following main topics:

  • What is TypeScript?
  • Why is TypeScript necessary?
