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.

Snapshot testing

Snapshot testing is a useful tool to test that there are no unwanted changes in your user interface. Jest generates snapshot files when the snapshot tests are executed. The next time the tests are executed, the new snapshot is compared to the previous one. If there are changes between the content of the files, the test case fails and an error message is shown in the Terminal.

To start snapshot testing, perform the following steps:

  1. Install the react-test-renderer package. The --save-dev parameter means that this dependency is saved to the package.json file's devDependencies part and it is only used for development purposes. If you type the npm install --production command in the installation phase, dependencies in the devDependencies part are not installed. So, all dependencies that are only required in the development phase should be installed using the...
