详解基于webpack2.x的vue2.x的多页面站点

leslie·Zhao 人气:0

本文介绍了基于webpack2.x的vue2.x的多页面站点,分享给大家,具体如下:

vue的多页面

依旧使用vue-cli来初始化我们的项目

然后修改主要目录结构如下:

├── build
│  ├── build.js
│  ├── check-versions.js
│  ├── dev-client.js
│  ├── dev-server.js
│  ├── utils.js
│  ├── vue-loader.conf.js
│  ├── webpack.base.conf.js
│  ├── webpack.dev.conf.js
│  └── webpack.prod.conf.js
├── src
│  ├── pages
│  │  ├── boys
│  │  │  ├── index.html
│  │  │  ├── index.js
│  │  │  └── index.vue
│  │  ├── goods
│  │  │  ├── index.html
│  │  │  ├── index.js
│  │  │  └── index.vue
│  │  ├── index
│  │  │  ├── index.html
│  │  │  ├── index.js
│  │  │  └── index.vue
│  │  └── sotho
│  │    ├── index.html
│  │    ├── index.js
│  │    └── index.vue

编写每个页面

可以看到这里我们有4个单独的页面,分别是boys,goods,index,sotho

首先看boys文件夹中的代码:

index.html

<!DOCTYPE html>
<html>
 <head>
  <meta charset="utf-8">
  <title>vue3</title>
 </head>
 <body>
  <div id="app"></div>
  <!-- built files will be auto injected -->
 </body>
</html>

这个是我们要单独生成的页面,最后也是生成index.html

index.vue

<style scoped>
 .boys {
  background-color: red;
 }
</style>
<template>

 <div id="app" class="boys">
  boys got many things.
 </div>

</template>
<script>

export default {
 name: 'boys'
}

</script>

这是我们的vue文件,可以看成一个组件,其实.vue文件你可以看成一个语法糖,最终会被vue-loader编译成js,生成对应的css,js,dom

index.js

import Vue from 'vue'
import Index from './index.vue'

Vue.config.productionTip = false

new Vue({
 el: '#app',
 template: '<Index/>',
 components: { Index }
})

这就是主要文件了,这里执行vue的实例化,用法同在浏览器端页面中直接引入vue.js文件一样的含义

其他几个页面一样也是同理,具体可以见:

修改webpack.config.js

由于vue中的配置使用了模块化管理,所以我们需要修改下面两个文件:

1、webpack.base.conf.js

我们需要修改webpack.base.conf.js的入口entry,这是配置多入口文件的重点!

如果不懂多入口含义的化,建议去看下webpack的文档。

webpack.base.conf.js

...

module.exports = {
 entry: {
  'pages/boys/index': './src/pages/boys/index.js', //配置boys页面入口
  'pages/goods/index': './src/pages/goods/index.js', //配置goods页面入口
  'pages/index/index': './src/pages/index/index.js', //配置index页面入口
  'pages/sotho/index': './src/pages/sotho/index.js', //配置sotho页面入口
 },
...

2、webpack.dev.conf.js

这里我们需要修改plugins,它是个强大的即插即用的拓展。

我们使用html-webpack-plugin来生成我们的对于的页面。

...
var HtmlWebpackPlugin = require('html-webpack-plugin')
...

...

module.exports = merge(baseWebpackConfig, {
 ...
 plugins: [
  new webpack.DefinePlugin({
   'process.env': config.dev.env
  }),
   new HtmlWebpackPlugin({
   filename:'./pages/boys/index.html', //指定生成的html存放路径
   template:'./src/pages/boys/index.html', //指定html模板路径
   inject: true, //是否将js等注入页面,以及指定注入的位置'head'或'body'
   chunks:['pages/boys/index'] //需要引入的chunk(模块资源),不配置就会引入所有页面的资源(js/css),这是个很重要的属性,你可以不配置试试效果
  }),
  new HtmlWebpackPlugin({
   filename:'./pages/goods/index.html',
   template:'./src/pages/goods/index.html',
   inject: true,
   chunks:['pages/goods/index']
  }),
  new HtmlWebpackPlugin({
   filename:'./pages/index/index.html', 
   template:'./src/pages/index/index.html',
   inject: true,
   chunks:['pages/index/index']
  }),
  new HtmlWebpackPlugin({
   filename:'./pages/sotho/index.html',
   template:'./src/pages/sotho/index.html',
   inject: true,
   chunks:['pages/sotho/index']
  }),
  ...
 ]
})

以上就是我们进行多页开发的主要配置项。

开发环境访问页面

运行npm run dev,我们看下怎么访问我们的多页vue应用。

  • http://localhost:9090/pages/index/index.html 访问index页面
  • http://localhost:9090/pages/boys/index.html 访问boys页面
  • http://localhost:9090/pages/goods/index.html 访问goods页面
  • http://localhost:9090/pages/sotho/index.html 访问sotho页面

再来看下我们的dom结构是什么样:

页面里的js就是我们通过插件注入的,并且我们是通过指定chunks完成。

build

运行npm run build

➜ vue2-x-multiple git:(master) ✗ npm run build

 Build complete.

 Tip: built files are meant to be served over an HTTP server.
 Opening index.html over file:// won't work.

到此为止,一个简单的基于vue2.x的多页应用完成了。

升级

webpack.base.conf.js中的entry入口都是手工写入,如果页面多的话这样肯定有问题。

所以我们通过如下的方式来自动完成这段代码:

var entryJS = glob.sync('./src/pages/**/*.js').reduce(function (prev, curr) {
  prev[curr.slice(6, -3)] = curr;
  return prev;
}, {});

这里的 './src/pages/**/*.js' 我们按照一定的规则去匹配我们的入口j s即可。

生成的的是:

{ 'pages/boys/index': './src/pages/boys/index.js',
 'pages/goods/index': './src/pages/goods/index.js',
 'pages/index/index': './src/pages/index/index.js',
 'pages/sotho/index': './src/pages/sotho/index.js' }

与我们想要的行为一致

同样我们也升级下我们的webpack.dev.conf.js中的plugins

var htmls = glob.sync('./src/pages/**/*.html').map(function (item) {
  return new HtmlWebpackPlugin({
    filename: './' + item.slice(6),
    template: item,
    inject: true,
    chunks:[item.slice(2, -5)]
  });
});

module.exports = merge(baseWebpackConfig, {
 module: {
  rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap })
 },
 // cheap-module-eval-source-map is faster for development
 devtool: '#cheap-module-eval-source-map',
 plugins: [
  new webpack.DefinePlugin({
   'process.env': config.dev.env
  }),
  // https://github.com/glenjamin/webpack-hot-middleware#installation--usage
  new webpack.HotModuleReplacementPlugin(),
  new webpack.NoEmitOnErrorsPlugin(),
  // https://github.com/ampedandwired/html-webpack-plugin
  new FriendlyErrorsPlugin()
 ].concat(htmls)
})

生成的是:

HtmlWebpackPlugin {
 options:
  { template: './src/pages/boys/index.html',
   filename: './pages/boys/index.html',
   hash: false,
   inject: true,
   compile: true,
   favicon: false,
   minify: false,
   cache: true,
   showErrors: true,
   chunks: [ 'pages/boys/index' ],
   excludeChunks: [],
   title: 'Webpack App',
   xhtml: false } }
