.setState(produce cant infer type

[mordv]

Bug Description

const a = userStore.setState(
  produce((d) => {
    d.b = 2;
  })
);

Can't infer type. d is any.

setState(s => produce(s, (d) => { works though

@mordv you should use immer middleware -> https://zustand.docs.pmnd.rs/middlewares/immer

immer middleware changes for all usage. using produce selectively might be a good use case.

[dbritto-dev]

might be better to create a copy mutate the copy but for this case the right way to use it is:

state => produce(state, draft => { ... })

setState(s => produce(s, (d) => { works though

Sounds like a good workaround.
