- [Narrator] In this video…you're going to learn about HATEOAS…and how it can be implemented in two different ways…in the JaxOS application.…So what is HATEOAS?…Well first off,…it stands for Hypermedia As The Engine of Application State.…But what does this really mean?…Well what it means in practical terms…is that a client is given a way…to navigate through and API…purely by using hypermedia.…This is often in the form of http links…generated by an API's backend application.…The overreaching objective…is to decouple the client from the application…in such a way that the application…can change independently of the client.…
Okay, that might sound a little confusing…so let's walk through few examples…to see how this might work.…So here we have a simplified Book resource…which is represented by the JSON data string here.…You have already learned that…this JSON representation of a book…is obtained by the client when it…makes a GET request to this URL.…But what URI does the application need to call…in order to delete or update the book?…
Join Alex Theedom as he guides you through a wide range of topics, including how to define resource endpoints, how to add dynamism to your application with hypermedia, how to maintain data integrity with Bean Validation, and how to process messages with the JSON Processing API. Once you have completed this course, you'll be ready to develop your own client and server RESTful APIs.
