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.

Declaring routes

We will start this section by creating a page component that lists the app’s products. We will then learn how to create a router and declare routes using React Router’s createBrowserRouter function.

Creating the products list page

The products list page component will contain the list of the React tools in the app. Carry out the following steps to create this:

  1. We will start by creating the data source for the page. First, create a folder called data in the src folder and then a file called products.ts within data.
  2. Add the following content into products.ts (you can copy and paste it from the GitHub repository at https://github.com/PacktPublishing/Learn-React-with-TypeScript-2nd-Edition/blob/main/Chapter6/src/data/products.ts):
    export type Product = {
      id: number,
      name: string,
      description: string,
      price: number,
    };
    export const products: Product[] = [
