Measuring Modularity in JavaScript-Based Microservices from Software Architectural Perspectives

Abstract

As businesses embrace concepts for rapid, scalable, and maintainable software systems, microservices adoption is gaining traction. Meanwhile, the current work on software architecture metrics focuses mainly on measuring modularity metrics in object-oriented programming, particularly in the Java environment. To address this gap, we propose a method for measuring fundamental quality attributes coupling and cohesion to evaluate architectural modularity specifically in the context of JavaScript-based microservices. In addition, we conduct a case study with coupling and cohesion measurement methods for evaluating architectural modularity in JavaScript-based microservices. We finally discuss future directions of refining these metrics in the dynamic context of microservices design. © 2023 Copyright for this paper by its authors.
