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

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 } }
