Overview of this book

Reading, navigating, and debugging a large frontend codebase is a major issue faced by frontend developers. This book is designed to help web developers like you learn about ReactJS and TypeScript, both of which power large-scale apps for many organizations. This second edition of Learn React with TypeScript is updated, enhanced, and improved to cover new features of React 18 including hooks, state management libraries, and features of TypeScript 4. The book will enable you to create well-structured and reusable React components that are easy to read and maintain, leveraging modern design patterns. You’ll be able to ensure that all your components are type-safe, making the most of TypeScript features, including some advanced types. You’ll also learn how to manage complex states using Redux and how to interact with a GraphQL web API. Finally, you’ll discover how to write robust unit tests for React components using Jest.

Using React Hooks

In this chapter, we will learn about React’s common Hooks and how to use them with TypeScript. We will implement the knowledge of all these Hooks in a React component that allows a user to adjust a score for a person. We will start by exploring the effect Hook and begin to understand use cases where it is useful. We will then delve into two state Hooks, useState and useReducer, understanding when it is best to use each one. After that, we will cover the ref Hook and how it differs from the state Hook, and then the memo and callback Hooks, looking at how they can help performance.

So, we’ll cover the following topics:

  • Using the effect Hook
  • Using state Hooks
  • Using the ref Hook
  • Using the memo Hook
  • Using the callback Hook
