Dynamic Frontend Architecture for Runtime Component Versioning and Feature Flag Resolution in Regulated Applications
Year: 2025
Type: article
Abstract: Regulated web systems require traceable, rollback-safe UI delivery, yet conventional static deployments and Boolean flagging struggle to provide per-user versioning, deterministic fallbacks, and audit-grade observability. The objective of this research is to develop and validate a runtime frontend architecture that enables per-session component versioning with deterministic fallbacks and audit-grade traceability for regulated systems. We present a dynamic frontend architecture that integrates typed GraphQL flag schemas, runtime module federation, and structured observability to enable per-session and per-route component versioning with deterministic fallbacks. We formalize a version-resolution function v = f(u, r, t) and implement a production system that achieved a 96% reduction in MTTR, a P90 fallback rate below 0.7%, and over 280 k session-level logs across 45 days. Compared to static delivery and standard flag evaluators, our approach adds schema-driven targeting, component-level isolation, and audit-ready render traces suitable for compliance. Limitations include cold-start overhead and governance complexity; we provide mitigation strategies and discuss portability beyond fintech.
