Abstract:
Web applications are a critical part of any enterprise business system. Recently, we
have observed maturity in technologies that enable the separation of frontend and
backend. While backend systems have largely evolved toward microservices
architectures, frontend development has predominantly remained monolithic. Micro
Frontends have emerged as a solution to the typical monolithic frontend. However,
there is no predominant approach to implementation that satisfies the different
practical requirements of a state-of-the-art web application. The goal of this work is to
develop an architectural framework for implementing micro frontends to address
challenges experienced in current implementations, such as inconsistent user
experience, managing security and authorization among different micro frontends, and
handling complexity in development. To achieve this, the study reviews both
horizontal and vertical decomposition approaches for Micro Frontend design,
examines the challenges associated with each method, and draws insights from
existing implementations and practitioner literature. Based on this analysis, a coherent
architectural framework is developed, encompassing team organization, domain
decomposition, composition strategies, testing, and deployment design. In conclusion,
the proposed architectural framework provides a formalized approach that reduces
adoption risks for organizations considering Micro Frontend Architecture by making
key architectural decisions explicit and traceable. The architectural framework is
intended as a practical reference guide rather than a rigid prescription.
