安裝Nprogress

npm install nprogress -S

在main.js中引入Nprogress

import NProgress from 'nprogress';
import 'nprogress/nprogress.css';

路由攔截器裡使用Nprogress

注意在router.beforeEach裡一定要加上next()否則路由不會跳轉

router.beforeEach((to, from, next) => {
  NProgress.start();
  next()
});

router.afterEach(transition => {
  NProgress.done();
})
 
;

main.js檔案最後如下

import Vue from 'vue'
import App from './App'
import router from './router'
import Mixin from './mixins';
import filters from './filters';
import NProgress from 'nprogress';
import 'nprogress/nprogress.css';
Vue.mixin(Mixin);

Vue.config.productionTip = false
Object.keys(filters).forEach(k =>
 
 Vue.filter(k, filters[k]));

router.beforeEach((to, from, next) => {
  NProgress.start();
  next()
});

router.afterEach(transition => {
  NProgress.done();
});

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})
