mobx-state-tree (mst) is an addition to mobx. While mobx is a rather generic approach to manage state via composable observables and actions, mst is a strongly opinionated enhancement of it that brings in e.g. strong typing and some simplifications. While mst was great for some simple things, it soon runs into issues at complex requirements, one of them being performance. In my scenarios after running into some of these issues, I then rebuilt everything in mobx and brought in the strong typing etc. via TypeScript and code governance. This worked great so far, not much boilerplate, great state/action componentisation, also a great serialization/deserialization out of the box with serializr.
