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.

Handling lists with React

For list handling, we will learn about the JavaScript map() method, which is useful when you have to manipulate a list. The map() method creates a new array containing the results of calling a function on each element in the original array. In the following example, each array element is multiplied by 2:

const arr = [1, 2, 3, 4];
const resArr = => x * 2); // resArr = [2, 4, 6, 8]

The following example code demonstrates a component that transforms an array of integers into an array of list items and renders these inside the ul element:

import React from 'react';
function MyList() {
  const data = [1, 2, 3, 4, 5];
  return (
        { =>
          <li>Listitem {number}</li>)
export default MyList;

The following screenshot shows what the component looks like when it is rendered. If you open the console...
