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.

    Output:

    2.1.1
  2. Create your project, called buystuff, via the Create React App CLI:
    $ npx create-react-app buystuff 
  3. Delete all the unnecessary files for our project.

    Delete App.css, delete the contents of App.js except for the import and export statements, and delete logo.svg.

  4. Build the App React component as a class component but leave it blank.
  5. In App.js, change the import statement at the top:
    import React, {Component} from "react";
  6. Then add the following component definition:
    class App extends Component {
      render() {
        return <div className="App"/>;
      }
    }
  7. Build the Header React component as a functional component inside App.js. Its only prop should be title, which contains...
