Hands-On Full Stack Development with Spring Boot 2 and React - Second Edition

By: Juha Hinkula

Overview of this book

React Hooks have changed the way React components are coded. They enable you to write components in a more intuitive way without using classes, which makes your code easier to read and maintain. Building on from the previous edition, this book is updated with React Hooks and the latest changes introduced in create-react-app and Spring Boot 2.1. This book starts with a brief introduction to Spring Boot. You’ll understand how to use dependency injection and work with the data access layer of Spring using Hibernate as the ORM tool. You’ll then learn how to build your own RESTful API endpoints for web applications. As you advance, the book introduces you to other Spring components, such as Spring Security to help you secure the backend. Moving on, you’ll explore React and its app development environment and components for building your frontend. Finally, you’ll create a Docker container for your application by implementing the best practices that underpin professional full stack web development. By the end of this book, you’ll be equipped with all the knowledge you need to build modern full stack applications with Spring Boot for the backend and React for the frontend.

  1. Spring Security provides security services for Java-based web applications.
  2. You have to add the Spring Security starter package dependency to your pom.xml file. You can configure Spring Security by creating a security configuration class.
  3. JSON Web Token (JWT) is a compact way to implement authentication in modern web applications. The size of the token is small, and so it can be sent in the URL, either in the POST parameter or inside the header.
  4. You can use the Java JWT library, that is, the JWT library for Java. The authentication service class adds and reads the token. The filter classes handle the login and authentication process.
  5. You have to add the Spring Boot test starter package to your pom.xml file. The Spring Boot test starter package provides a lot of nice testing utilities—for example, JUnit, AssertJ, and Mockito. When using the JUnit, the basic test...
