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.

Routing with React Router

In this chapter, we will build a simple app implementing the following pages:

  • A home page that welcomes the user
  • A products list page that lists all the products
  • A product page that provides details about a particular product
  • An admin page for privileged users

This will all be managed using a library called React Router.

Through this, we will learn how to implement static links from the products list to the product page and implement route parameters on the product page for the product ID. We will also learn about form navigation and query parameters when it comes to the search feature of our app.

Finally, the chapter will end with how to lazily load code for a page to improve performance.

So, in this chapter, we will cover the following topics:

  • Introducing React Router
  • Declaring routes
  • Creating navigation
  • Using nested routes
  • Using route parameters
  • Creating an error page
  • Using index routes...
