• Solve real-world problems relating to building modern web applications
• Gain a thorough understanding of how data moves through different React components

Book Description

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.

What you will learn

• Use JSX to include logic in the view layer of applications
• Get familiar with the important methods and events in the React lifecycle
• Distinguish between class and functional component syntaxes
• Create forms with Formik and handle errors
• Understand the React Hooks API and the problems it can solve
• Fetch outside data using the Axios library and populate the data to the app

Who this book is for
