REST next level : Crafting domain-driven web APIs

Julien Topçu - Shodo

You have just coded your business logic by applying the principles of Domain-Driven Design! But when comes the time to write your API, you are facing a serious issue! All the intention and the expression of your domain go up in smoke to fit the blankness methods GET, POST, etc.

Denatured by the REST layer, the business workflow is then deported on the consumer side to compensate for the limited vocabulary of this well-known CRUD protocol…

During this talk, we will see how to bring the business intent back inside the REST API by finally being able to expose our domain services and aggregates’ methods. The business workflow will also be encapsulated in the REST API in order to have the power to guide our consumers through the workflow of our domain.
