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.

Like HOCs, render props help us reuse the code between components and help us avoid repeating the same code. On the other hand, unlike HOCs, which take a component and return an updated component, render props take a function and return a React element. In the next exercise, we are going to do exactly the same as what we did for HOCs, that is, we'll update the color of the donation amount if the amount is bigger than 50.

The details object we mentioned previously will be the same and we are going to update it from the Animal component.

Exercise 7.07: Adding donationColor

In this exercise, similar to what we did for the HOC function exercise, we are going to create a render prop function and check if the amount of the donation is greater than 50. If it's greater than 50, we will change the...
