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.

Summary

In this chapter, we have learned how to pass data so that components can communicate with each other. There are various ways to pass data between components, and this chapter has covered all the essential methods of sending data to other components at different levels. Throughout this chapter, we looked at building an Endangered Animals app that showed us a list of animals along with a status of whether the animal is endangered or not. It also allowed us to submit new animal details.

First, we discussed how to send data from a parent to a child component. As React only allows us to pass data to a child component from a parent component, it is essential to understand how we can send data through props down to the child components first.

Then, we learned how to pass different types of props, including strings, numbers, Booleans, arrays, and components. We also learned about two important advanced React concepts, higher-order components and render props. Both techniques...
