There was a problem hiding this comment.
Third argument is getServerSnapshot - in case of effector there is no difference with client version

@AlexandrHoroshih Oh, yeah. I see that https://github.com/AlexandrHoroshih/effector/blob/react-18/package.json#L96-L99 |
keep old fixture for backward compatibility tests
effector-react must be updated to work correctly with react-18, but at the same time it should not break react-17 compatiblity
due to substitution of react-18 to react-17 sids may be different each time
TODO: remove, once react-17 support is deprecated
bug is not reproduced, hmm
react-dom of 18 renders empty string slightly different, but it is not a concern of tests for effector-react at all also IS_REACT_ACT can just be always true, since react-17 does not know about that
refactor react 17 script
Previous custom implementation prevented re-computation of `fn`, if none of the keys in `useStoreMap` was changed This test catches this behaviour and will pass with previous implementation, but currently it fails with the new one, based on official `use-sync-external-store`, since `useSyncExternalStoreWithSelector` does not accept keys Need to add some custom memoization for that in the new implementation
It is needed to comply with previous behavior of useStoreMap
inline condition instead of function, one return instead of few
