vue-prerender-webpack-plugin's Introduction

vue-prerender-webpack-plugin

npm version

NPM

利用Vue的SSR实现编译预渲染webpack插件,在编译过程中生成页面骨架屏,提高页面性能和体验,提高首屏

使用

安装

$ npm install vue-prerender-webpack-plugin

在webpack配置中使用插件

const VuePrerenderWebpackPlugin = require('vue-prerender-webpack-plugin');
const skeleton = require('./skeleton'); // vue服务端渲染的webpack配置
 
module.exports = {
    ...
    plugins: [
        ...
        new VuePrerenderWebpackPlugin({
            config: skeleton,
        }),
        ...
    ],
    ...
}

在使用编译预渲染插件vue-prerender-webpack-plugin需要传入vue服务端渲染的webpack配置,可以参考 Vue.js Server-Side Rendering Guide

具体webpack配置参考 example 中 skeleton 中的配置

页面结构

预渲染插件中使用了Vue的SSR,所以页面结构应该按照 SSR源码结构,如下:

app.js
import Vue from 'vue';
import App from './index.vue';

const app =  new Vue({
    components: {
        App
    },
    template: '<app />',
});

export default app;
index-normal.js
import app from './app';

app.$mount('#app');

export default app;
index-skeleton.js
import app from './app';

export default app;
index.html
<div id="app">
    <!--vue-ssr-outlet-->
</div>

实例

example

执行实例

example/vue-prerender 文件夹下,执行以下脚本:

$ npm run dev # 编译预渲染,本地开发

$ npm run dev:normal # 正常编译

$ npm run dev --skeleton # 指定页面进行编译

$ npm run build # 编译预渲染,打包

$ npm run build:normal # 正常编译,打包

$ npm run build --skeleton # 指定页面进行编译,打包

效果

截图:

1、首屏时间:正常构建页面需要js执行完之后渲染首屏(3000ms),而预渲染构建在HTML加载完的时候就渲染首屏了(500ms)

2、编译预渲染会在编译过程中将组件空状态编译到HTML中,能一定程度上减少初次渲染的 DOM 节点数以节省 Virtual DOM 的初始化开销

实现

注意

该插件依赖html-webpack-plugin插件
