export default {
  namespaced: true,
  state: {
    array: []
  },
  getter: {
    loading: ({array}) => array.length > 0
  },
  mutation: {
    PUSH(state, payload) {
      state.array.push(payload)
    },

}

somewhereInStore.js

payload = await query.someQuery(variables, { commit })

要はお互い依存しなくてもcommit渡したらなんとかなる
