I don’t think microservice architecture ever really had much momentum. Consultants like ThoughtWorks, who seem to write a lot about building software but may not actually build much software, certainly tried to promote it, but I’m skeptical that it was ever widely adopted.
I think the way it is right now is just perfect, you got npm integration for more than you could ever dream of, and you also have a bunch of agreed core packages providing a proper orchester to basically start playing any song you want.
