Optimizing WordPress Architecture: A next-generation approach with Micro-Frontends

The micro-frontend architecture represents a truly important paradigm shift in the realm of frontend web development. However, integrating it with the monolithic WordPress approach seems to be impossible due to the lack of valuable interoperability work in this area. The goal of this article is to increase the previously mentioned interoperability level between WordPress and the micro-frontend architecture. It presents improvements and optimizations to a WordPress solution that facilitates easy integration with micro-frontends: automatic performance measurements and rollback support for and elevated developer experience; multi-layered security architecture; real-world scenarios with data gathered from real users; static assets delivery unified experience with the WordPress ecosystem, for improved performance. Industry-scale testing shows an increase of more than 400% in the delivery stability of micro-frontend-enabled webpages with a minuscule decrease in the First Content Paint (FCP) key performance indicator of the application. This paper made unique and novel advances to the field of interoperability while taking into account many technical and real-world-related aspects.
