Very nice post, happy to hear Taylor from Zalando is giving some inspiration, defenitely this is a good path to split a big app into smaller parts which can be manteinable indepently and can be scalable. I’m curious about how to set up rules between apps and the umbrella where all apps are rendered, can an app be rendered inside another app? Do all pieces need to be rendered together? Even if there are many apps how to keep a consistent ui between them. I hope these questions help to polish this good initiative.
