vue-easy-renderer

vue-easy-renderer 是一个基于 vue-server-renderer 的服务端渲染工具,他提供了更简单的方式来实现vue的服务端渲染,支持koa.jsexpress.js

安装

npm install vue-easy-renderer -S

Peer Dependency

npm i vue vuex vue-router vue-loader vue-server-renderer -S

Example

首先创建一个vue文件,路径如下 component/hello_word/hello_word.vue

<template>
  <div>hello {{world}}</div>
</template>
<style scoped>
</style>
<script>
  export default {
    name: 'HelloWorld',
    data() {
      return {
        world: ''
      };
    }
  }
</script>

express.js为例创建以下文件

'use strict';

const path = require('path');
const express = require('express');
const vueEasyRenderer = require('vue-easy-renderer').connectRenderer;

const renderer = vueEasyRenderer(path.resolve(__dirname, './component'));
const app = express();

app.use(express.static('./dist'));
app.use(renderer);

app.get('/', (req, res) => res.vueRender('hello_world/hello_world.vue', {world: 'world!'}));

app.listen(8081);

console.log('vue-easy-renderer express example start in 127.0.0.1:8081');
module.exports = app;

最后浏览器获取到的html

<html>
<head>
 <script>window.__VUE_INITIAL_STATE__ = {"world":"world!"};</script>
</head>
<body>
  <div server-rendered="true" data-v-30ca8d89>hello world!</div>
</body>
</html>

Component Head

我们可以在组件中设置html的头部

<template>
  <div id="app" class="hello">hello {{world}}</div>
</template>
<style scoped>
</style>
<script>

  export default {
    name: 'HelloWorld',
    data() {
      return {
        world: ''
      };
    },
    head: {
      title: 'hello',
      script: [
        {src: "/hello_world.js", async: 'async'}
      ],
      link: [
        { rel: 'stylesheet', href: '/style/hello_world.css' },
      ]
    },
  }
</script>

最终渲染的结果

<html>
<head>
 <title>hello</title>
 <link rel="stylesheet" href="/style/hello_world.css"/>
 <script>window.__VUE_INITIAL_STATE__ = {"world":"world!"};</script>
 <script src="/hello_world.js" async="true"></script>
</head>
<body>
  <div id="app" server-rendered="true" class="hello" data-v-035d6643>hello world!</div>
</body>
</html>

vuex 和 vue-router

在服务端渲染中使用vuex或者vue-router时,我们需要为每个请求创建一个vuex或者vue-router实例,因此在根组件注入vuex或者vue-router实例时,需要在实例上添加一个工厂方法,该方法调用时返回一个实例,默认方法名为$ssrInstance,如:

vuex

const options = {
  state: {
    hello: 'world!'
  }
};

const store = new Vuex(options);
store.$ssrInstance = () => new Vuex(options);
export default store;

vue-router

const options = {
  mode: 'history',
  routes: [
    { path: '/user/:id', component: User }
  ]
})

const router = new VueRouter(options)
router.$ssrInstance = () => new Vuex(options);
export default router;

如果在服务端渲染中使用vue-router,需要设置modehistory
