Question: Did you use this package with React 17 about reusable HOT 10 OPEN

Hi, I haven't. @morsdyce ?

from reusable.

I haven't used react 17 yet due to some bugs occurring in component libraries but it's usually related to event handling and not state.

Could you reproduce the issue with any of the examples we have?

from reusable.

from reusable.

create store:

export const useStore = createStore(() => useState({}));

and use them:

const store = useStore()

returns store === null for the React 17

from reusable.

There is a different babel version in the react 17. Could it be a reason?

from reusable.

Babel shouldn't be the issue as we don't convert syntax using a babel plugin.
I tried reproducing a simple example with React 17 and it worked:

https://codesandbox.io/s/compassionate-fog-ltf4x?file=/src/App.js

It would really help if you could send an example of it not working correctly

from reusable.

one more note, I use react native. It not depends from react-dom

from reusable.

@gev could you reproduce the issue on expo? I don't have an environment ready for react-native

from reusable.

Can't reproduce at expo. All works as well.
On my envirenment bug exists when import custom hook from module.

from reusable.

create store:

export const useStore = createStore(() => useState({}));

and use them:

const store = useStore()

returns store === null for the React 17

We had a very similar issue in react-native with React 17 that appears to be caused by the import for the store not actually executing the imported file until a function from it is used. With stores that usually happens within the render method, during which you don't want to be changing around your stores. The solution was to add an "empty" import of the store directly to our App.tsx: import 'stores/thestore'
