Avoiding hidden monoliths

Some micro frontend frameworks attempt to visually divide the UI, but that’s not how real applications work. In reality, an application is a blend of various parts from different subdomains, converging to create a cohesive whole. While these subdomains can be neatly separated conceptually, they often coalesce within the same layout elements for the end user.

Although some micro frontend frameworks attempt to segment the UI visually, this alone is often insufficient. Real applications require that backend logic and data flow are also segmented in alignment with the UI to avoid hidden monoliths.

Consider a web store: product details and order history may reside in separate subdomains, yet users expect coherence. They wouldn’t want to see just product IDs in their order history; they expect product names and relevant details. Consequently, these subdomains visually merge for the user.

Almost every subdomain contributes something to shared...
