In the new brave world of decoupled and autonomous microservices, there’s a lot of knowledge, best practices and attention given to APIs. But once you start integrating these APIs in a UI, it quickly becomes a monolith of highly coupled components that replicate a lot of the functionality provided in the underlying APIs.
As everyone probably knows and agrees to by now, monoliths are not a design goal. By making your UI compositional through hosted views and by moving some of the business logic from the client to the server through the use of hypermedia, you can achieve full vertical integrations that are horizontally decoupled in a microservice fashion all the way from the persistence layer and up to the user interface.
