Как отобразить vue -progressbar?

Используемый vue -progressbar: https://github.com/hilongjw/vue-progressbar

api-ax ios. js создает экземпляр ax ios, используя URL-адрес, с которого он будет извлекаться.

Данные извлекаются, но индикатор выполнения не отображается. В консоли браузера нет ошибок.

Любая помощь будет принята с благодарностью.

app. js: 

require('./bootstrap');

import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)

import Vuelidate from 'vuelidate'
Vue.use(Vuelidate)

import { BootstrapVue, IconsPlugin } from 'bootstrap-vue'
Vue.use(BootstrapVue)
Vue.use(IconsPlugin)

import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'

import PostComponent from './components/PostComponent'
import PortalComponent from './components/PortalComponent'

import App from './components/App'

const router = new VueRouter({
        base: '/',
        mode: 'history',
        history: true,

        routes: [
        {
            path: '/',
            name: 'home',
            component: PostComponent,
            meta: {
              progress: {
                func: [
                  {call: 'color', modifier: 'temp', argument: '#ffb000'},
                  {call: 'fail', modifier: 'temp', argument: '#6e0000'},
                  {call: 'location', modifier: 'temp', argument: 'top'},
                  {call: 'transition', modifier: 'temp', argument: {speed: '1.5s', opacity: '0.6s', termination: 400}}
                ]
              }
            }
        },
        {   path: '/portal/:id', 
            component: PortalComponent 
        },
    ],
});

import VueProgressBar from 'vue-progressbar'

const options = {
  color: '#bffaf3',
  failedColor: '#874b4b',
  thickness: '5px',
  transition: {
    speed: '0.2s',
    opacity: '0.6s',
    termination: 300
  },
  autoRevert: true,
  location: 'left',
  inverse: false
}

Vue.use(VueProgressBar, options)

export default new Vue({
    el: '#app',
    components: { App },
    router,
    }).$mount('#app')

i use nprogress really simple progress bar
import 'nprogress/nprogress.css' main.js
service.js(axios goes here)
import NProgress from 'nprogress' service.js

const apiClient = axios.create({
  baseURL: `http://localhost:3000`,
  withCredentials: false, // This is the default
  headers: {
    Accept: 'application/json',
    'Content-Type': 'application/json'
  },
  timeout: 15000
})
//start when you start done when you finish (i use interceptors)
 apiClient.interceptors.request.use(config => {
   NProgress.start()
   return config
 })

 apiClient.interceptors.response.use(response => {
   NProgress.done()
   return response
 })

each time api call has been made it runs the progress bar and finish when the content has been loaded.
hope it help
