For anyone struggling with the complexity and boilerplate of Redux, at my day job we added Redux Toolkit (the newly recommended add-on by the Redux project itself!) and it solves most of the verbosity issues! We use it to share all our state logic over mobile and web and it works excellently now. I'd actually recommend Redux w/ Redux-Toolkit, for the first time ever.
There's a library called rematch that's been implementing most of these ideas for a long time, but sadly it didn't get popular enough and it seems to be somewhat lacking maintenance. It was such a pleasure to use (in comparison) that I just can't believe how people ever work with those massive switch statements.
One of the reasons we created Redux Toolkit was to eliminate the need to write those switch statements :) (also action type strings, action creators, object spreads, having to split logic for one feature across multiple files, and all the other "boilerplate" concerns that users rightfully complained about over the years.)
