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.

Using form navigation

In this section, we will use React Router’s Form component to navigate to the products list page when the search criteria are submitted. Form is a wrapper around the HTML form element that handles the form submission on the client side. This will replace the use of useNavigate and simplify the code. Carry out the following steps:

  1. In Header.tsx, start by removing useNavigate from import for the React Router and replace it with the Form component:
    import {
      NavLink,
      Link,
      useSearchParams,
      Form
    } from 'react-router-dom';
  2. In the JSX, replace the form element with React Router’s Form component:
    <Form
      className="relative text-right"
      onSubmit={handleSearchSubmit}
    >
      <input ... />
    </Form>
  3. In the Form element in the JSX, remove the onSubmit handler. Replace this with the following action attribute so that the form is sent to the products...
