Type inference lost when exported/imported as module

[willwinberg]

Hi. I have a large Vue 2 application that utilizes my store modules in many different places. I'm also using this awaesome package ("vuex-composition-helpers": "^1.0.21") along with ("@vue/composition-api": "^1.0.2") My vuex modules are all typed and I have an accessor file that looks like this

@/composables/organizationStore.ts
import { createNamespacedHelpers } from 'vuex-composition-helpers'
import {
  OrganizationState,
  OrganizationGetters,
  OrganizationActions,
  OrganizationMutations
} from '@/store/modules/organization/organizationTypes'

export const {
  useState: useOrganizationState,
  useGetters: useOrganizationGetters,
  useActions: useOrganizationActions,
  useMutations: useOrganizationMutations
} = createNamespacedHelpers<
  OrganizationState,
  OrganizationGetters,
  OrganizationActions,
  OrganizationMutations
>('organization')

and i import it in to relevant components like so. However, when I access it in the setup method, the types are lost.

Organizations.vue
...
import { useOrganizationState, useOrganizationGetters, useOrganizationActions, useOrganizationMutations } from '@/composables/organizationStore'
...
setup() {
...
const { organizationAlert } = useOrganizationGetters(['organizationAlert'])
< const organizationAlert: any > :[
...

It works though if I do all of the configureation directly in the component:

Organizations.vue
...
import { createNamespacedHelpers } from 'vuex-composition-helpers'
import {
  OrganizationState,
  OrganizationGetters,
  OrganizationActions,
  OrganizationMutations
} from '@/store/modules/organization/organizationTypes'
const {
  useState: useOrganizationState,
  useGetters: useOrganizationGetters,
  useActions: useOrganizationActions,
  useMutations: useOrganizationMutations
} = createNamespacedHelpers<
  OrganizationState,
  OrganizationGetters,
  OrganizationActions,
  OrganizationMutations
>('organization')
...
setup() {
...
const { organizationAlert } = useOrganizationGetters(['organizationAlert'])
< organizationAlert(state: OrganizationState): AlertOptions > :D
...

My main goal here is to eliminate having to repeat all the above code in every component that uses the store and rather just use: ie. import { useOrganizationGetters } from '@/composables/organizationStore'

Is this even possible? I can't find out for the life of me what I'm missing here.

Hi!

Would you care to add a unit test / set of unit tests that apply to your case? It will help me find the solution.

Thanks.

Sorry, forgot to update this. For some reason, modifying my accessor file to this fixed the issue:

@/composables/organizationStore.ts
import { createNamespacedHelpers } from 'vuex-composition-helpers'
import {
  OrganizationState,
  OrganizationGetters,
  OrganizationActions,
  OrganizationMutations
} from '@/store/modules/organization/organizationTypes'

const {
  useState,
  useGetters,
  useActions,
  useMutations
} = createNamespacedHelpers<
  OrganizationState,
  OrganizationGetters,
  OrganizationActions,
  OrganizationMutations
>('organization')

export const useOrganizationState = useState
export const useOrganizationGetters = useGetters
export const useOrganizationActions = useActions
export const useOrganizationMutations = useMutations
