Unidirectional Circular Dataflow Architecture for Real-Time Updates The capability to present data in real-time is an essential feature to be considered when architecting modern web applications. Examination of the origin, progress and obstacles of web applications reveals how it influenced the current state of how web applications are implemented to deliver data in real-time. This research aims to investigate an alternative and reproducible approach to address real-time, moving away from outdated requisites and not extending existing implementations. When considering real-time systems, how to build an architecture that satisfies its requirements? Based on the review of the literature, understanding the current context of web applications and exploring available libraries and frameworks, an architecture is proposed broken down in layers that are responsible for ensuring each of the real-time system’s requisites. An open source library is implemented developed to wrap and abstract the implementation of the unidirectional flow. The results show that not only the unidirectional data flow architecture is theoretically superior addressing such requisites, but also more maintainable. Further research is needed to run more comparisons, also to explore the usage of this approach outside the scope of the web applications.
