Overview of this book

Are you interested in how React takes command of the view layer for web and mobile apps and changes the data of large web applications without needing to reload the page? This workshop will help you learn how and show you how to develop and enhance web apps using the features of the React framework with interesting examples and exercises. The workshop starts by demonstrating how to create your first React project. You’ll tap into React’s popular feature JSX to develop templates and use DOM events to make your project interactive. Next, you’ll focus on the lifecycle of the React component and understand how components are created, mounted, unmounted, and destroyed. Later, you’ll create and customize components to understand the data flow in React and how props and state communicate between components. You’ll also use Formik to create forms in React to explore the concept of controlled and uncontrolled components and even play with React Router to navigate between React components. The chapters that follow will help you build an interesting image-search app to fetch data from the outside world and populate the data to the React app. Finally, you’ll understand what ref API is and how it is used to manipulate DOM in an imperative way. By the end of this React book, you’ll have the skills you need to set up and create web apps using React.

Frequently in web applications, we interact with the user to capture valuable information, such as their usernames, passwords, and preferences. Whether we want to register a new user, complete a bank statement, fill in a survey, or perform an advanced search using certain criteria and filters, or for any such similar cases, we have to use forms.

Since forms are an important aspect in any frontend development, the React team provided us with the minimum toolkit to customize forms based on our needs. There is a straightforward API called Formik, which works by leveraging existing functionality in JavaScript that allows us to write more portable and reusable code while dealing with forms.

The goal of this chapter is to convey to you a deep understanding of how forms work in React, composing resilient form elements as quickly as possible through a number of practical examples. We will cover all the various types of form handling techniques in React, from uncontrolled...
