[Vue.js] Can't use cookies in Store.js file Subscribe to RSS

when trying to change the use of localStorage to cookies because i need to work with subdomains. When i use this.$cookie.set() or get() in any .vue.js file i can use with no problem but when i use in any .js file i get the following:

TypeError: Cannot read property ‘set’ of undefined.

when using vue-cookie btw.

here is my store.js file:

import vue.js from “vue”;
import Vuex from “vuex”;
import axios from “./axios-auth.js”;
import globalAxios from “axios”;
import router from “./router”;
import VueCookie from ‘vue-cookie’;

export default new Vuex.Store({
state: {
token: null,
userId: null,
expireIn: null,
segmentoSelecionado: null,
codigoTransfSelecionado: null
actions: {
login({ commit }, authData) {
.post(“/auth”, {
username: authData.username,
password: authData.password,
returnSecureToken: true
.then(res => {
const now = new Date().getTime();
const expirationDate = new Date(now + 3500000).getTime();
this.$cookie.set(‘userToken’,, {domain: ‘’});
commit(“authUser”, {
userToken: this.$cookie.get(‘userToken’),
.catch(error => console.log(error));

Solution :

How it looks to me

Vue.use(VueCookie) : extends the vue.js object, adding the $cookie functionality

Vuex does not inherit from Vue, so will not have the $cookie functionality

Try using the $cookie on the vue.js object, not the Vuex one:

Vue.$cookie.set(‘userToken’,, {domain: ‘’});
