基于webpack2.x的vue2.x的多页面站点

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:

  • https://github.com/zhaoqize/vue-advance/tree/master/vue2-multiple
  • https://git.oschina.net/zqzjszqzjs/vue2-x-multiple

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:

  • 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
  },
...
  • 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

  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 } }
