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.

Preface
React was built by Meta to provide more structure to its code base and allow it to scale much better. React worked so well for Facebook that they eventually made it open source. Today, React is the dominant technology for building the frontend of an application; it allows us to build small, isolated, and highly reusable components that can be composed together to create complex frontends.
TypeScript was built by Microsoft to help developers more easily develop large JavaScript-based programs. It is a superset of JavaScript that brings a rich type system to it. This type system helps developers to catch bugs early and allows tools to be created to robustly navigate and refactor code.
This book will teach you how to use both of these technologies to create large, sophisticated frontends that are easy to maintain.
Who this book is for
If you are a developer who wants to create large and complex frontends with React and TypeScript, this book is for you. The book doesn’t assume you have any previous knowledge of React or TypeScript – however, basic knowledge of JavaScript, HTML, and CSS will help you get to grips with the concepts covered.
What this book covers
, , covers the fundamentals of building React components. This includes defining component output using JSX, making a component configurable using props, and making a component interactive using states.
, , is all about the fundamentals of TypeScript and its type system. This includes using inbuilt types, as well as creating new types.
, , explains how to create a project for React and TypeScript development. The chapter then moves on to how to create React components that use TypeScript to make props and states type-safe.
, , details the common React hooks and their typical use cases. The chapter also covers how to use the hooks with TypeScript to make them type-safe.
, , walks through how to style React components using several different approaches. The benefits of each approach are also explored.
, , introduces a popular library that provides client-side routing for applications with multiple pages. It covers how to declare the paths for the pages and how to create links between them. It also covers how to implement page parameters for highly dynamic pages.
, , explores how forms can be implemented using several different approaches, including the use of a popular library. The benefits of each approach are also included.
, , walks through how states can be shared between different components. Several approaches are explored, along with their benefits.
, , demonstrates how React components can interact with a REST API. The chapter steps through an approach using core React and then an alternative approach using a popular library.
, , shows how React components can interact with a GraphQL API. The chapter details how this can be done using two different popular libraries.
, , brings in several patterns for making React components highly reusable but still type-safe.
, , first delves into how functions can be tested with Jest. The chapter then moves on to how React components can be tested with the help of the React Testing Library.
