[RTKQ] How to access getState API in invalidatesTags?

[Grapedge]

Assuming we have the following API endpoint:

const api = createApi({
  baseQuery: fetchBaseQuery(),
  tagTypes: ['Post'],
  endpoints: (builder) => ({
    getPosts: builder.query({
      query: (userId) => `/posts-by-user/${userId}`,
      providesTags: (res, err, userId) => [
        {
          type: 'Post',
          id: userId,
        },
      ],
    }),
    getPost: builder.query({
      query: (postId) => `/post/${postId}`,
      providesTags: (res, err, postId) => [{ type: 'Post', id: postId }],
    }),
    deleteUser: builder.mutation({
      query: (userId) => `/user/del/${userId}`,
      invalidatesTags: (res, err, userId) => {
        // how to get state here? should we import from 'app/store'?
        const posts = selectPostsByUser(getState(), userId)
        return [...posts.map((post) => ({ type: 'Post', id: post.id })), { type: 'Post', id: userId }]
      },
    }),
  }),
})

Sometimes, we have to access store to invalidate the tags, but how to access store here?

• import store from app/store?
• by queryFn?

Is there any good way to deal with this caching problem? Thanks for your reply!
