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.

Fetching Data with React

In this section, we are going to use Axios inside React and fetch data from the endpoint we have tested with Postman.

Exercise 14.08: Creating a Controlled Component to Fetch Data

In this exercise, we will first need to update a functional component to a class-based component as we will need to initialize the state of the component. Then we will create a controlled search form component. We will then create an Axios request in order to fetch images using the NASA API. Perform the following steps:

  1. Update the current functional App (used in the previous exercise) component to the class-based component. The code should now look like this:
    import React, { Component } from 'react';
    import './App.css';
    class App extends Component {
      render() {
        return (
      <div className="o-container">
          <h1>Search NASA images</h1>
      ...
