Philosophy
You can always fix a bug in a library, but a bad architecture will turn your entire project into Hell.
With that in mind, I have been on a never ending quest to find a simple but effective architecture to easily build mobx / react apps in particular. The journey so far has lead me to the following three points for a happy developer experience.
App architecture design fundamentals
Note: these principles can be applied to any kind of software, Bard router was made to allow such implementations in a react / mobx context.
Clean architecture by Robert C. Martin (Uncle Bob)
“By separating the software into layers, and conforming to The Dependency Rule, you will create a system that is intrinsically testable, with all the benefits that implies.”
Decouple state and UI by mobx author
"Strategies for dealing with routing, data fetching, authentication and workflow testing without the UI layer."

App shell architecture
"An application shell (or app shell) architecture is one way to build a Progressive Web App that reliably and instantly loads on your users' screens, similar to what you see in native applications."
