Zustand persist individual slices (zustand-x library instead?)

Hi guys!

Anyone used this 3rd party abstraction of Zustand?
I want to know if I might be running into any pitfalls

https://github.com/udecode/zustand-x

An issue I have with the base Zustand library is with persisting only specific slices in my global store.

To accomplish this I have to either create a separate store or use the

partialize

partialize

function which seems very boilerplatey and annoying to work with on a bigger scale (I might be wrong here, this is just what I'm getting from the documentation)

However with the zustand-x library (formerly known as zustood), a lot of boilerplate is removed, and you can persist individual stores.

Example (pay attention that you don't need to create getters or setters when writing your stores either - but you can extend both the selectors and actions on the store if you need to):

export const authStore = createStore('auth')(
  {
    session: undefined,
    user: undefined,
  },
  {
    persist: {
      name: 'auth',
      storage: createJSONStorage(() => zustandStorage),
    },
  },
);

export const authStore = createStore('auth')(
  {
    session: undefined,
    user: undefined,
  },
  {
    persist: {
      name: 'auth',
      storage: createJSONStorage(() => zustandStorage),
    },
  },
);
