I like pizza. I like it a lot. I want to use the sensation of ordering a pizza to demonstrate how easy it can be to develop microservices with contemporary and modern methodology - that being the API First! approach.

In this lightning session I will show on the beamer how easy it is to write a small OpenAPI Spec for a tiny microservice. I will use the mighty OpenAPI Code Generator to generate initial projects from this spec file for a couple of programming languages.

So the generator automatically does a lot of work for you, taking the task of project setup and the writing of boiler plate code off you shoulders.

This demonstration will show that developing the "API First! way" can save you a lot of time and also forces you to think first of a clean and understandable API before you implement it. Thus enabling you to design awesome APIs to be used by consuming applications.

The developers who are going to use your API to build their own applications will thank you for that.

You should bring with you a basic understanding of microservice development. Furthermore, it will help you to be able to read YAML code, as I write it live on the beamer.
