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。
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

进入dist目录,查看生成的页面

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 } }
