A Scalable Micro-Frontend Architecture for Enterprise-Grade Web Platforms

Abstract

Enterprise-grade web platforms, burdened by years of development on monolithic frontend applications, face critical scalability bottlenecks that obstruct parallel feature development and technology evolution. The tightly coupled nature of these codebases leads to low development velocity, complex deployment cycles, and painful technology stagnation. This paper proposes the Scalable Micro-Frontend Architecture (SMFA), a framework that applies the principles of service decomposition (Microservices) to the client-side. SMFA decomposes the monolithic frontend into independent, deployable units governed by strict interface contracts and composed via a centralized orchestration layer. The model relies on runtime integration strategies and strict isolation techniques to prevent global namespace and styling conflicts. The empirical evaluation, grounded in the context of an enterprise platform transition, focuses on organizational and technical scaling. We demonstrate that SMFA drastically improves development agility by enabling decoupled deployment and significantly reducing the complexity of major technology upgrades. SMFA provides a robust, verifiable blueprint for organizations seeking to align frontend development with modern continuous delivery practices and achieve sustained architectural flexibility in complex web environments.
