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.

Promises

The traditional way to handle an asynchronous operation is to use callback functions for the success or failure of the operation. If the operation succeeds, the success function is ­called; otherwise, the failure function is called. The following (abstract) example shows the idea of using a callback function:

function doAsyncCall(success,  failure) {
  // Do some API call
  if (SUCCEED)
    success(resp);
  else
    failure(err);
}
success(response) {
  // Do something with response
}
failure(error) {
  // Handle error
}
doAsyncCall(success, failure);

Nowadays, promises are a fundamental part of asynchronous programming in JavaScript. A promise is an object that represents the result of an asynchronous operation. The use of promises simplifies the code when you’re executing asynchronous calls. Promises are non-blocking. If you are using an older library for asynchronous operations that doesn’t support promises, the code becomes much more difficult...
