Client side state is not available in server side.

When the state is updated in getServerSideProps or in getStaticProps, the HYDRATE action is called on client side to sync it with server side state, however the opposite is not happening. The server instance of the store always gets the initial state, not the client side state. What should be done in order to access client side state in getServerSideProps to render the page based on that state ?

@kyun server ALWAYS have default state by design. You can use cookies to authenticate users and some server middlewares to cache portions of state for clients. This lib has nothing to do with this though, it’s app responsibility.

It is completely out of scope of this package. You can sync state back to server by doing API calls and or using something like Yjs. Server state is only a seed to speed up client side initial rendering, nothing more. Documentation refers only to that initial rendering on client side when client state is indeed the same as server had.
