Redux => MobX migration case study.

[jtwigg]

I just finished migrating from a Redux store to a Mobx store and thought I'd post some of my results here.

The chief reason I started the migration was
A) Redux boiler plate was out of control: Adding a simple "set boolean" to my state would require modifying multiple files and creating multiple declarations (Action ID's and action functions, reducers, etc)
B) React re-draws were out of control: Despite reading all the docs, I could never get redux re-draw's under control.

In total, the delta in code was

MobX: 790 lines of code
Redux: 1600 lines of code

So roughly 1:2 for MobX:Redux

However: This doesn't capture the other benefits

• My current MobX implementation actually does more. Redraws are correct and appropriate. I now have better async/thunk like behavior than I did previously.
• Everything is much easier to reason about.

So thank you all for helping me get my app state under control!

I really wish to see what you have done, if it is possible for you to share some gist of your code.
