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.

    In early 2019, React 16.8 was released with a stable release of React Hooks. As we discussed in the Chapter 15, Promise API and async/await.

    React Hooks allows us to use state and other features in the function components without writing a class. In this section, we are going to learn how to use React Hooks to refactor what we have done in the previous sections, such as fetching data or updating the state by clicking on either the Popularity or Trending buttons.

    In the class-based components, we have used the componentDidMount() method to initially fetch data, and the componentDidUpdate() method to re-fetch data upon re-rendering. To avoid the infinite loop, we used prevProps to compare whether the previous prop is the same as the current prop.

    With useEffect, we can do both initial requests and...
