I have news to announce regarding the book about designing APIs with OpenAPI and Swagger that I’m writing together with Josh Ponelat. We finished all chapters except for the appendixes and are now in the exciting final review phase. While the whole book is probably still a few weeks from production, this was an important milestone on the way, and we’re proud we made it this far.

Also, the first two chapters of the third part of the book - 16 and 17 - are now available on Manning’s website as part of the Manning Early Access Program (MEAP). In the third part, we’re taking the API from the sample application we have built during part two and refine it to improve the developer experience for an eventual release of the API. We also extend its functionality and discuss bringing in a new version of API. In chapter 16, we’re outlining the whole process and update our user stories and domain model. In chapter 17, we’re adding a new feature, which leads us to discuss composition keywords in OpenAPI that help design more complex and still reusable schemas.

If that’s something you’re interested in (I bet you are!), please pre-order the book, read the new chapters and let me know your feedback.
