Reduces Redux boilerplate and is clean to read
From 2 comments
Thanks for sharing those functions. Definitely cuts down on a lot of the boilerplate I see with Redux.
nathancahill on HNThe concept expressed in the title matches a desire. Looking forward to checking out and hearing other's experiences.

The Slider example is overwrought for a simple carousel
From 2 comments
I know it's just an example... But the Slider code is ridiculously overwrought. Building this type of image carousel is trivial with just plain HTML+CSS+JS. This example uses…
pavlov on HNJust to clarify, I'm not picking on you; I realize it's hard to come up with meaningful examples. The problem with Slider is that it doesn't readily extrapolate into anything…

Decorator syntax is unfamiliar and discouraged by React and Redux teams
From 2 comments
Looks pretty neat. My initial reactions: - I don't like the `@kea(...` because it's another bit of JS syntax I hadn't heard of before. Though I do like decorators in Python, I…
kasbah on HNIt's worth noting that both the React and Redux teams generally discourage the use of decorators. Quoting the Create-React-App README: > Create React App doesn’t support…

kasbah on HNHey, 1) As munchor pointed out, you don't need to use the decorators. See the "what is this @kea()" button in the first guide for more details: https://kea.js.org/guide/counter…

Requests
Better type safety, such as Flow or TypeScript support
From 2 comments
Is this type-safe? Can it infer the payload type somehow? With MobX you can write type-safe code, and it's pretty important in bigger code bases. Redux can be made type-safe but…
Ciantic on HNHi, propTypes are supported as an (optional) first class citizen. Thus whatever is the output of a reducer or a selector, provided it is passed to a react component, is type…

Less decorator-heavy API, with properties defined in the class
From 2 comments
I'm a big fan of decorators, but it seems like much of the React/Redux world is overly class-decorator happy. It's really common to define properties in a decorator which would…
spankalee on HN> That said, the magic with having a big options hash in the `@kea({})` call itself is that then you can easily disconnect the logic from your components as your application…

Questions
Why not just use plain React state for these examples
From 1 comment
Why not just use state, which seems like the correct solution to the examples?

How does it handle async flows like redux-saga
From 2 comments
If my favorite part of redux is structuring flows with redux-saga, does mobx-state-tree have a solution for me? For example, this is nice: ``` // On login, spin off the auth…
arstin on HNMST doesn't have the same restrictions as redux in terms of async so you don't need to do it in the same way. Edit: In MST it would look more like plain js: ``` class AuthStore()…

Looks nice, but I think I can get most of it using recompose, which I've been using extensively lately.

Redux boilerplate helpers from Redux docs
From 1 comment
Also worth noting that the Redux docs _specifically_ have a section called "Reducing Boilerplate" [0] that shows how to write functions like this, and my Redux addons catalog [1]…
