Context has any type for state

[Wesley (leydev)]

Describe the bug
I trying to make an middleware, that check if user is logged, so I need to access state in store of vuex. But de context parameter of middleware has state like any type.

const isLogged: Middleware = ({ store }: Context) => {
  store.state // this has any
}

To Reproduce
Steps to reproduce the behavior:

1. Make a empty nuxt typscript project version 2.15.8
2. Create a store with anything state
3. Create a middleware
4. Try to access state from store at context parameter with intelisense help

Expected behavior
When we use context the store must have types

Additional context
I tried to explicit declare store with follow code:

declare module '@nuxt/types' {
  interface Context {
    store: Store<RootState>
  }
}

But it's emits a error:

Subsequent property declarations must have the same type. Property 'store' must be of type 'Store', but here has type 'Store'.ts(2717)
index.d.ts(49, 3): 'store' was also declared here.
(property) Context.store: Store

You can try casting as RootState where RootState is the type declaration in your respective store

[Rafał Chłodnicki]

Yes, you have to manually cast the Store (or state). Vuex is not very type friendly.
