配置prerender-spa-plugin插件

const PrerenderSpaPlugin = require('prerender-spa-plugin')
 plugins: [
    // 预加载
    new PrerenderSpaPlugin(
      // 输出目录的绝对路径
      path.join(__dirname, '../dist'),
      // 预渲染的路由
      ['/home', '/a', '/b' ], 这里加home是为了做首页路由是`/`的预渲染，将`/`根目录重定向到`/home`
      {
        // 监听到自定事件时捕获
        renderAfterDocumentEvent: 'sketelon-render-event',// 呈现预渲染页面的时间，例如document.dispatchEvent(new Event('sketelon-render-event'))
      }
    ),
 ]

设置路由,模式为history

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import ssss from '../components/mode';
const a = () => import('../components/a')
const b = () => import('../components/b')
Vue.use(Router)

export default new Router({
  mode: 'history',
  routes: [
    {
      path: '/',
      name: 'HelloWorld',
      redirect: "/home"
    },
    {
      path: '/home',
      name: 'HelloWorld',
      component: HelloWorld
    },
    {
      path: '/a',
      name: 'HelloWorld',
      component: ssss(a, 'a')
    },
    {
      path: '/b',
      name: 'HelloWorld',
      component: ssss(b, 'b')
    }
  ]
})
