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. By the end of the book, you’ll be well-equipped to use both React and TypeScript.

Reusable Components

In this chapter, we will build a checklist component and use various patterns to make it highly reusable but still strongly typed.

We will start by using TypeScript generics to strongly type the data passed to the component. Then, we will use the props spreading pattern to make the component API-flexible, and allow consumers of the component to custom render parts of the component using the render props pattern. After that, we will learn how to make custom hooks and use this to extract logic for checked items and how to make the state within a component controllable to change the component’s behavior.

We’ll cover the following topics:

  • Creating the project
  • Using generic props
  • Using props spreading
  • Using render props
  • Adding checked functionality
  • Creating custom hooks
  • Allowing the internal state to be controlled
