关闭页面时无法在 firebase 上注销用户

Question

I'm developing a ERP program in vue/firebase. My problem is: I need to logout the user when he closes the browser or the page who running the program.

I tried to use the setPersistence, like the docs here: https://firebase.google.com/docs/auth/web/auth-state-persistence ; but it keeps returning an error of undefined atributes like here:

[Vue warn]: Error in created hook: "TypeError: Cannot read property 'Persistence' of undefined"
(found in Root)
warn                    @   vue.esm.js?efeb:628
logError                @   vue.esm.js?efeb:1893
globalHandleError       @   vue.esm.js?efeb:1888

Vue                     @   vue.esm.js?efeb:5094
eval                    @   main.js?3479:46

__webpack_require__     @   build.js:679
fn                      @   build.js:89
(anonymous)             @   build.js:2803
__webpack_require__     @   build.js:679
(anonymous)             @   build.js:725
(anonymous)             @   build.js:728

and also that:

TypeError: Cannot read property 'Persistence' of undefined
    at Vue.created (main.js?3479:51)
    at invokeWithErrorHandling (vue.esm.js?efeb:1863)
    at callHook (vue.esm.js?efeb:4228)
    at Vue._init (vue.esm.js?efeb:5017)

    at __webpack_require__ (build.js:679)
    at fn (build.js:89)
    at Object.<anonymous> (build.js:2803)

Like i said before i'm using vue.js to develop the solution, and put it on created() function in main.js, here's my code:

 import FirebaseVue from './firebase/index' import Vue from 'vue' import App from './App.vue' import router from './router' import money from 'v-money' import Vuelidate from 'vuelidate' import { BootstrapVue, IconsPlugin,LayoutPlugin,ModalPlugin,CardPlugin,VBScrollspyPlugin,DropdownPlugin, TablePlugin} from 'bootstrap-vue' import { library } from '@fortawesome/fontawesome-svg-core' import { FontAwesomeIcon } from '@fortawesome/vue-fontawesome' import { VueMaskDirective } from 'v-mask' import { faTimesCircle, faPlusCircle, faCoffee, faHome, faLogout, faSignOutAlt, faEdit, faUpload, faDollarSign, faTimes, faClock, faCheck, faChevronLeft, faChevronRight, faArrowCircleLeft, faArrowCircleRight, } from '@fortawesome/free-solid-svg-icons' library.add(faTimesCircle,faPlusCircle,faCoffee,faHome,faSignOutAlt,faEdit,faUpload,faDollarSign,faTimes,faClock,faCheck,faChevronLeft,faChevronRight,faArrowCircleLeft,faArrowCircleRight) Vue.component('font-awesome-icon', FontAwesomeIcon) Vue.use(BootstrapVue) Vue.use(IconsPlugin) Vue.use(LayoutPlugin) Vue.use(ModalPlugin) Vue.use(CardPlugin) Vue.use(VBScrollspyPlugin) Vue.use(DropdownPlugin) Vue.use(TablePlugin) Vue.use(FirebaseVue) Vue.use(require('vue-moment')); Vue.use(money, {precision: 4}) Vue.use(Vuelidate) new Vue({ router, render: h=>h(App), created(){ this.$firebase.auth().setPersistence(this.$firebase.auth.Auth.Persistence.SESSION), this.$firebase.auth().onAuthStateChanged( user => { let id_cliente = localStorage.getItem('id_cliente'); let firebase = this.$firebase.firestore(); if (user) { firebase.collection('sessoes_usuarios').doc(id_cliente).update({status:true}).then( console.log('usuário logado com sucesso') ).catch((e)=>{ console.log(e); console.log('não possui log de sessão') }); } else { firebase.collection('sessoes_usuarios').doc(id_cliente).update({status:false}).then( console.log('usuário deslogado com sucesso') ).catch((e)=>{ console.log(e); console.log('não possui log de sessão') }); } }) } }).$mount('#app')

Here's the firebase/index.js folder content:

import firebase from 'firebase/app'
import 'firebase/auth'
import 'firebase/storage'
import 'firebase/firestore'

export const firebaseApp = firebase.initializeApp({
  apiKey:             xxx,
  authDomain:         xxx,
  databaseURL:        xxx,
  projectId:          xxx,
  storageBucket:      xxx,
  messagingSenderId:  xxx,
  appId:              xxx      
})

export default function install (Vue) {
  Object.defineProperty(Vue.prototype, '$firebase', {
    get(){
      return firebaseApp
    }
  })
}

Am i missing somenthing?

Answer 1

I found the error, the problem is that i doens't import the auth library:

import 'firebase/auth'

I don't received any error logs before it.
