How to dispatch action from a javascript file (instead of a vue component)?

Question

I have one module(javascript file) outside of vue context. i need to dispatch action from this javascript file. is it possible ? if yes, then how ?

jsfile.js(Javascript file)

const detail = {};

detail.validateLocation = (location) => {
  // need to dispatch one action from here.
  // dispatch('SET_LOCATION', {city: 'California'})
  // how to dispatch action ?
}

export default detail;

action.js

export default {
  SET_LOCATION: ({ commit}, data) => {
    commit('SET_LOCATION', data);
  },
}

store.js

import Vue from 'vue';
import Vuex from 'vuex';
import actions from './actions';
import mutations from './mutations';
import getters from './getters';
export function createStore() {
  return new Vuex.Store({
    modules: {},
    state: {
      location: null
    },
    actions,
    mutations,
    getters,
  });
}

First, create the store in store.js.

import Vue from 'vue';
import Vuex from 'vuex';
import actions from './actions';
import mutations from './mutations';
import getters from './getters';

const store = new Vuex.Store({
    modules: {},
    state: {
      location: null
    },
    actions,
    mutations,
    getters,
  });

export default store

Then, import the store into jsfile.js and use it.

import store from "./store"

const detail = {};

detail.validateLocation = (location) => {
  // Use imported store
  store.dispatch('SET_LOCATION', {city: 'California'})
}

export default detail;

Assuming you have a main or index file that creates your Vue instance, you now likely need to change the import from importing the create function to simply importing the store.
