The Spring Boot application that we created in Chapter 5, Securing and Testing Your Backend, is required, together with the modification from Chapter 10, Setting Up the Frontend for Our Spring Boot RESTful Web Service (the unsecured backend).

We also need the React app that we used in Chapter 11, Adding CRUD Functionalities (carfront).

The following code samples available at the GitHub link will also be required: https://github.com/PacktPublishing/Hands-On-Full-Stack-Development-with-Spring-Boot-2-and-React-Second-Edition/tree/master/Chapter12.
