Overview of this book

If you’re an existing Java developer who wants to go full stack or pick up another frontend framework, this book is your concise introduction to React. In this three-part build-along, you’ll create a robust Spring Boot backend, a React frontend, and then deploy them together. This new edition is updated to Spring Boot 3 and includes expanded content on security and testing. For the first time ever, it also covers React development with the in-demand TypeScript. You’ll explore the elements that go into creating a REST API and testing, securing, and deploying your applications. You’ll learn about custom Hooks, third-party components, and MUI. By the end of this book, you'll be able to build a full stack application using the latest tools and modern best practices.

Handling events with React

Event handling in React is similar to handling DOM element events. The difference compared to HTML event handling is that event naming uses camelCase in React. The following sample component code adds an event listener to a button and shows an alert message when the button is pressed:

function MyComponent() {
  // This is called when the button is pressed
  const handleClick = () => {
    alert('Button pressed');
  return (
      <button onClick={handleClick}>Press Me</button>
export default MyComponent;

As we learned earlier in the counter example, you have to pass a function to the event handler instead of calling it. Now, the handleClick function is defined outside the return statement, and we can refer to it using the function name:

// Correct
<button onClick={handleClick}>Press Me</button>
// Wrong
<button onClick={handleClick()}>Press Me</button>
