Hands-On Full Stack Development with Spring Boot 2.0 and React

Overview of this book

Apart from knowing how to write frontend and backend code, a full-stack engineer has to tackle all the problems that are encountered in the application development life cycle, starting from a simple idea to UI design, the technical design, and all the way to implementing, testing, production, deployment, and monitoring. This book covers the full set of technologies that you need to know to become a full-stack web developer with Spring Boot for the backend and React for the frontend. This comprehensive guide demonstrates how to build a modern full-stack application in practice. This book will teach you how to build RESTful API endpoints and work with the data access Layer of Spring, using Hibernate as the ORM. As we move ahead, you will be introduced to the other components of Spring, such as Spring Security, which will teach you how to secure the backend. Then, we will move on to the frontend, where you will be introduced to React, a modern JavaScript library for building fast and reliable user interfaces, and its app development environment and components. You will also create a Docker container for your application. Finally, the book will lay out the best practices that underpin professional full-stack web development.

Technical requirements


The Spring Boot application that we created in Chapter 4, Securing and Testing Your Backend, is needed (GitHub: https://github.com/PacktPublishing/Hands-On-Full-Stack-Development-with-Spring-Boot-2.0-and-React/tree/master/Chapter%204).

We also need the React app that we used in the previous chapter (GitHub: https://github.com/PacktPublishing/Hands-On-Full-Stack-Development-with-Spring-Boot-2.0-and-React/tree/master/Chapter%2011).

Using Jest

Jest is a test library for JavaScript and it is developed by Facebook (https://facebook.github.io/jest/en/). Jest is widely used with React and it provides lots of useful features for testing. You can create a snapshot test, where you can take snapshots from React trees and investigate how states are changing. Jest also has mock functionalities that you can use to test, for example, your asynchronous REST API calls. Jest also provides functions that are needed for the assertions in your test cases.

We will first see how you can create...
