I am using VueJS in conjunction with vuex
and vue-router
. I have a vuex
module that is making a mutation to its store, and trying to use that to determine whether or not a user is authenticated.
Here is what my code looks like in relevant part.
main.js
import Vue from 'vue'
import App from './App.vue'
import store from './store'
import router from './router'
router.beforeEach((to, from, next) => {
console.log(router.app) // prints a Vue$2 object
console.log(router.app.$store) // undefined
console.log(store.getters.isAuthenticated) // false
...
}
const app = new Vue({
store,
router,
...App
})
app.$mount('#app')
/store/index.js
import Vue from 'vue'
import Vuex from 'vuex'
import core from './modules/core'
Vue.use(Vuex)
const store = new Vuex.Store({
modules: {
core: core
}
})
export default store
/store/modules/core.js
import * as types from '../types'
import api from '../../api'
import router from '../../router'
const state = {
token: null,
user: null,
authenticated: false
}
const mutations = {
[types.LOGIN_SUCCESS] (state, payload) {
console.log('mutate')
state.token = payload.token
state.user = payload.user
state.authenticated = true
router.go('/')
}
}
const getters = {
isAuthenticated: state => {
return state.authenticated
}
}
const actions = {
[types.LOGIN] (context, payload) {
api.getToken(payload).then(response => {
context.commit(types.LOGIN_SUCCESS, response)
})
}
}
export default {
state,
mutations,
actions,
getters
}
When I go thru my logic to trigger the LOGIN
action, I can see that the mutation executed properly, and when I use the Chrome extension to view the vuex state for my core
module, the state for user
and authenticated
have been properly mutated.
QUESTION
It seems like this module just simply has not been loaded by the time the router is running in the .beforeEach
loop. Is this true?
If yes, what are some other suggestions on how to handle this situation? If no, what am I doing incorrect?
console.log(store.state.core.authenticated)
return false because you not make a login yet.
In your code you not persist user info in anywhere. E.g. using localstorage
Same considerations:
router.app.$store
, use store
that you importLOGIN_SUCCESS
mutation, store login info and token into localstoragebeforeEach
hook, check localstorage, if was populated with token, get user information and apply the mutation. If not, just call login pageSomething like this..
const mutations = {
[types.LOGIN_SUCCESS] (state, payload) {
state.token = payload.token
state.user = payload.user
state.authenticated = true
localstorage.setItem('token', payload.token)
localstorage.setItem('user', payload.user)
}
}
const actions = {
[types.LOGIN] (context, payload) {
return api.getToken(payload).then(response => {
context.commit(types.LOGIN_SUCCESS, response)
return response
})
}
}
router.beforeEach((to, from, next) => {
let user = localstorage.getItem('user')
let token = localstorage.getItem('token')
if (user && token) {
store.commit(types.LOGIN_SUCCESS, {token, user})
next()
}
else if (!store.getters.isAuthenticated) {
store.dispatch(types.LOGIN).then(() => next())
} else {
next()
}
}
