The ADDR process is designed to be able to incorporate many of the concepts of DDD. We use event storming, encourage event storming during the align phase to try to surface things. The idea is to bring in boundaries where we can segment parts of the API. High cohesion is about having related functionality grouped together in the same code base.
“API design centers on effective communication, not just between developers, but also communication that combines product thinking, business, and technology all in one."
James Higginbotham is the author of “Principles of Web API Design” and an executive API consultant. In this episode, James explained why it is extremely important to design APIs properly and shared the five key important principles of API design taken from his book. James also recommended the API Design-First approach–a rapid & lightweight outcome-based API design process–to design and deliver APIs successfully, including the ADDR process and establishing API boundaries (in relation to DDD). Towards the end, James shared some recommendation for API testing strategies and also some anti-patterns that we should avoid.
