I'm feeling a bit lost when it comes to working with Vuex store components.
How can I access the state of another module? I've tried various methods to retrieve data from the store, but I always end up with an Observer object. What is the correct way to interact with this observer?

Whenever I try to directly access anything from this object using rootState.user.someVariable, I receive an undefined response.
Getting state from components is not an issue for me.
Edit. Add code
User module
import * as Constants from './../../constants/constants'
import * as types from '../mutation-types'
import axios from 'axios'
const state = { user: [] }
const getters = {
getUser: state => state.user
}
const actions = {
getUserAction ({commit}) {
axios({method: 'GET', 'url': Constants.API_SERVER + 'site/user'})
.then(result => {
let data = result.data
commit(types.GET_USER, {data})
}, error => {
commit(types.GET_USER, {})
console.log(error.toString())
})
}
}
const mutations = {
[types.GET_USER] (state, {data}) {
state.user = data
}
}
export default { state, getters, actions, mutations }
Mutations
export const GET_LANGS = 'GET_LANGS'
export const GET_USER = 'GET_USER'
Store
import Vuex from 'vuex'
import Vue from 'vue'
import user from './modules/user'
import lang from './modules/lang'
Vue.use(Vuex)
const store = new Vuex.Store({
modules: {
user,
lang
}
})
Main app
import Vue from 'vue'
import App from './App'
import router from './router'
import store from './store/index'
Vue.config.productionTip = false
new Vue({
el: '#app',
router,
store,
template: '<App/>',
components: { App }
})
Lang module, where I am attempting to access the store
import * as types from '../mutation-types'
import {axiosget} from '../../api/api'
const state = { langList: [] }
const getters = {
getLangs: state => state.langList
}
const actions = {
// these two actions give me similar results
getLangsAction (context) {
axiosget('lang') // described below
},
getAnotherLangsAction (context) {
console.log(context.rootState.user) <---- getting an Observer object
}
}
const mutations = {
[types.GET_LANGS] (state, {data}) {
state.langList = data
}
}
export default { state, getters, actions, mutations }
axiosget action, API module
import * as Constants from './../constants/constants'
import store from '../store/index'
import axios from 'axios'
export const axiosget = function (apiUrl, actionSuccess, actionError) {
console.debug(store.state.user) // <---- obtaining an Observer object, as previously mentioned
// should append user token to axios url, located at store.state.user.access_token.token
axios({method: 'GET', 'url': Constants.API_URL + apiUrl
+ '?access_token=' + store.state.user.access_token.token})
.then(result => {
let data = result.data
// todo implement this
// }
}, error => {
if (actionError && actionError === 'function') {
// implement this
}
})
}
Component that calls dispatcher. If I access the state via mapGetters in computed properties - there are no issues
<template>
<div>
{{user.access_token.token}}
</div>
</template>
<script>
import { mapGetters } from 'vuex'
export default {
name: 'ArticlesList',
computed: mapGetters({
user: 'getUser'
}),
created () {
this.$store.dispatch('getLangsAction')
this.$store.dispatch('getAnotherLangsAction')
}
}
</script>
In this code snippet, my goal is to retrieve the user's access token on the main site after login, and all subsequent data manipulations will be carried out via the API host.
