    //  [App.vue specific] When App.vue is finish loading finish the progress bar
    this.$Progress.finish()
  },
  created () {
    //  [App.vue specific] When App.vue is first loaded start the progress bar
    this.$Progress.start()
    //  hook the progress bar to start before we move router-view
    this.$router.beforeEach((to, from, next) => {
      //  does the page we want to go to have a meta.progress object
      if (to.meta.progress !== undefined) {
        let meta = to.meta.progress
        // parse meta tags
        this.$Progress.parseMeta(meta)

      //  start the progress bar
      this.$Progress.start()

      next()
    })
    //  hook the progress bar to finish after we've finished moving router-view

--- Accessing the progress bar externally through the vue instance (e.g. axios interceptors)
main.js
// main.js from Usage section

Vue.use(VueProgressBar, options)

export default new Vue({ // export the Vue instance
  ...App
}).$mount('#app')
api-axios.js
import axios from 'axios';
import app from '../main'; // import the instance

const instance = axios.create({
    baseURL: '/api'
});

instance.interceptors.request.use(config => {
    app.$Progress.start(); // for every request start the progress
    return config;
});

instance.interceptors.response.use(response => {
    app.$Progress.finish(); // finish when a response is received
    return response;
});

export default instance; // export axios instace to be imported in your app
