How do I type the persist middleware StorePersist type?

[JDaoMothership]

Originally I had:

import type { StoreApi } from 'zustand'
...
export const createMyStore = (customParams: MyParams): StoreApi<MyStore> => {
  return createStore<MyStore>()(
     ...
  )
}

And now I am trying to add the persist middleware:

import type { StoreApi } from 'zustand'
...
export const createMyStore = (customParams: MyParams): StoreApi<MyStore> => {
  return createStore<MyStore>()(
     persist(
         ...
     )
  )
}

But StoreApi does not have the persist object in the return value.

And I see the store type is now defined as Write<StoreApi<MyStore>, StorePersist<MyStore, MyStore>>

but Write and StorePersist are not exported as types from the zustand/middleware import, so I am not sure how best to type the return function here! Am I missing the best practice for this?

I am on zustand version 4.5.2.

@JDaoMothership those wouldn't be exposed in the future

Is there a reason for that? I feel like exposing those types here makes sense for this use case, right? Or am I approaching this incorrectly somehow?

[dbritto-dev]

@JDaoMothership those are more like for library authors that's why we didn't expose them

[JDaoMothership]

I understand, but I guess I'm wondering if this use case is valid, wouldn't it make sense to expose them? Or if it's not valid, I'm wondering what a better way to approach this is! :)

@JDaoMothership the best approach is to infer types as much as possible, explicit types could be tricky and not easy to maintain

In that case you could use ReturnType<typeof createMyStore>
