It is indeen wonderfully easy to work with. However, it has some performance penalties. I found typescript in conjunction with pure MobX just as efficient.

Especially complex state de-/serialization is a breeze with serializr.

Yeah exactly, for my use case (mobile device, frequent state updates) I couldn’t justify the overhead of state-tree after doing some profiling. Shame as it looks great and would have been a good fit ofberwise.

Thanks for the pointer to serializr - I hadn’t seen that before!
