Summary

In this chapter, you learned about the basic concepts of the REST architecture style and its key concepts – resources, URI, HTTP methods, and HATEOAS. Now, you know how REST, which is based on HTTP, simplifies and makes the integration of different applications and services easier.

We also explored the different HTTP concepts that allow you to write REST APIs in a meaningful way. We also learned why HATEOAS is an integral part of REST implementation. Additionally, we learned the best practices for designing REST APIs. We also went through an overview of our e-commerce app. This sample app will be used throughout the book.

The REST concepts you learned in this chapter will provide the foundation for REST implementation. Now, you can make use of the best practices you learned in this chapter to design and implement state-of-the-art REST APIs.

In the next chapter, you’ll learn about the fundamentals of the Spring Framework.
