How to get type from StoreDefinition

[Joebayld]

I'm using typescript and I want to reference the type of the store (state, getters, actions) in a variable. What is the best way to extract the type from a store definition?

Also - I created my own store maker as I'm adding the IDs dynamically later, so here is my current code to create the store definition. What I want is a variable that references the Store with the types working accordingly.

I've tried type StoreType = ReturnType<() => typeof widgetStore>; but I can't then convert that to a Store. Any ideas?

function makeWidgetStore<
  S extends StateTree = {},
  G extends _GettersTree<S> = {},
  A = {},
>(
  options: Omit<DefineStoreOptions<string, S, G, A>, "id">,
): StoreDefinition<string, S, G, A> {
  // @ts-ignore
  return options;
}

export const widgetStore = makeWidgetStore({
  state: () => {
    return {
      testString: "testS",
    };
  },
  getters: {
    caps: (state) => state.testString.toUpperCase(),
  },
  actions: {
    randomize() {
      this.$state.testString = nanoid();
    },
  },
});

// here I want to reference a creates store
const currentStore: WidgetStoreType  | null = null // not sure how to create WidgetStoreType
