Model-Driven Generation of Microservice Interfaces: From LEMMA Domain Models to Jolie APIs

Abstract: We formally define and implement a translation from domain models in the LEMMA modelling framework to microservice APIs in the Jolie programming language. Our tool enables a software development process whereby microservice architectures can first be designed with the leading method of Domain-Driven Design, and then corresponding data types and service interfaces (APIs) in Jolie are automatically generated. Developers can extend and use these APIs as guides in order to produce compliant implementations. Our tool thus contributes to enhancing productivity and improving the design adherence of microservices.
