Daniel: A lot of engineers when they do work, sometimes they don't think about what impact or what values they bring to the largest society. So I think that's a pretty good reminder for us to actually know and align what exactly the value we bring to the users and the customers out there. And best if we could bring it to the world, right? That's pretty impactful. Thank you so much for your time today. I really learned a lot about API design pattern and hopefully all the listeners here also learn a lot from you. It was a pleasant discussion.
“A good API doesn’t expose the internal data models or internal logic too much. And the more your clients are not under your control, the less you want to do that."
Daniel Luebke is a software architect and the co-author of “Patterns for API Design”. In this episode, we discussed some API design patterns and best practices taken from his book. Daniel first shared the importance of understanding domain requirements for building APIs and several API and message best practices, such as API first design, how to design loosely coupled message exchanges, the tradeoff between generic and specialized API operations, and the risk of exposing too much internal data model and logic in our APIs. Daniel also introduced the microservices domain-specific languages (MSDL) as an alternative to Open API for specifying APIs independent of the technology implementation. Towards the end, Daniel explained the importance of defining the API lifecycle, how to support backward compatibility, and the different API versioning strategies we can use to evolve our APIs.
