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复制代码编写每个页面
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>复制代码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>复制代码这是我们的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 = falsenew Vue({el: '#app',template: '<Index/>',components: { Index }
})
复制代码这就是主要文件了，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},
...复制代码- 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']}),...]
})复制代码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

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;
}, {});复制代码这里的'./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' }复制代码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 developmentdevtool: '#cheap-module-eval-source-map',plugins: [new webpack.DefinePlugin({'process.env': config.dev.env}),// https://github.com/glenjamin/webpack-hot-middleware#installation--usagenew webpack.HotModuleReplacementPlugin(),new webpack.NoEmitOnErrorsPlugin(),// https://github.com/ampedandwired/html-webpack-pluginnew FriendlyErrorsPlugin()].concat(htmls)
})复制代码生成的是：
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 } }复制代码
