准备工作
在本地用vue-cli新建一个项目，首先安装vue-cil，命令：
npm install -g vue-cli
新建一个vue项目,创建一个基于"webpack"的项目,项目名为vuedemo：
vue init webpack vuedemo
这里有一个地方需要改一下，在执行npm install命令之前，在package.json里添加一个依赖,后面会用到。
修改webpack配置

在这一步里我们需要改动的文件都在build文件下，分别是：
- utils.js
- webpack.base.conf.js
- webpack.dev.conf.js
- webpack.prod.conf.js
utils.js文件
// utils.js文件 var path = require('path') var config = require('../config') var ExtractTextPlugin = require('extract-text-webpack-plugin') exports.assetsPath = function (_path) { var assetsSubDirectory = process.env.NODE_ENV === 'production' ? config.build.assetsSubDirectory : config.dev.assetsSubDirectory return path.posix.join(assetsSubDirectory, _path) } exports.cssLoaders = function (options) { options = options || {} var cssLoader = { loader: 'css-loader', options: { minimize: process.env.NODE_ENV === 'production', sourceMap: options.sourceMap } } // generate loader string to be used with extract text plugin function generateLoaders(loader, loaderOptions) { var loaders = [cssLoader] if (loader) { loaders.push({ loader: loader + '-loader', options: Object.assign({}, loaderOptions, { sourceMap: options.sourceMap }) }) } // Extract CSS when that option is specified // (which is the case during production build) if (options.extract) { return ExtractTextPlugin.extract({ use: loaders, fallback: 'vue-style-loader' }) } else { return ['vue-style-loader'].concat(loaders) } } // https://vue-loader.vuejs.org/en/configurations/extract-css.html return { css: generateLoaders(), postcss: generateLoaders(), less: generateLoaders('less'), sass: generateLoaders('sass', { indentedSyntax: true }), scss: generateLoaders('sass'), stylus: generateLoaders('stylus'), styl: generateLoaders('stylus') } } // Generate loaders for standalone style files (outside of .vue) exports.styleLoaders = function (options) { var output = [] var loaders = exports.cssLoaders(options) for (var extension in loaders) { var loader = loaders[extension] output.push({ test: new RegExp('\.' + extension + '$'), use: loader }) } return output } /* 这里是添加的部分 ---------------------------- 开始 */ // glob是webpack安装时依赖的一个第三方模块，还模块允许你使用 *等符号, 例如lib/*.js就是获取lib文件夹下的所有js后缀名的文件 var glob = require('glob') // 页面模板 var HtmlWebpackPlugin = require('html-webpack-plugin') // 取得相应的页面路径，因为之前的配置，所以是src文件夹下的pages文件夹 var PAGE_PATH = path.resolve(__dirname, '../src/pages') // 用于做相应的merge处理 var merge = require('webpack-merge') //多入口配置 // 通过glob模块读取pages文件夹下的所有对应文件夹下的js后缀文件，如果该文件存在 // 那么就作为入口处理 exports.entries = function () { var entryFiles = glob.sync(PAGE_PATH + '/*/*.js') var map = {} entryFiles.forEach((filePath) => { var filename = filePath.substring(filePath.lastIndexOf('/') + 1, filePath.lastIndexOf('.')) map[filename] = filePath }) return map } //多页面输出配置 // 与上面的多页面入口配置相同，读取pages文件夹下的对应的html后缀文件，然后放入数组中 exports.htmlPlugin = function () { let entryHtml = glob.sync(PAGE_PATH + '/*/*.html') let arr = [] entryHtml.forEach((filePath) => { let filename = filePath.substring(filePath.lastIndexOf('/') + 1, filePath.lastIndexOf('.')) let conf = { // 模板来源 template: filePath, // 文件名称 filename: filename + '.html', // 页面模板需要加对应的js脚本，如果不加这行则每个页面都会引入所有的js脚本 chunks: ['manifest', 'vendor', filename], inject: true } if (process.env.NODE_ENV === 'production') { conf = merge(conf, { minify: { removeComments: true, collapseWhitespace: true, removeAttributeQuotes: true }, chunksSortMode: 'dependency' }) } arr.push(new HtmlWebpackPlugin(conf)) }) return arr } /* 这里是添加的部分 ---------------------------- 结束 */
webpack.base.conf.js 文件
// webpack.base.conf.js 文件 var path = require('path') var utils = require('./utils') var config = require('../config') var vueLoaderConfig = require('./vue-loader.conf') function resolve(dir) { return path.join(__dirname, '..', dir) } module.exports = { /* 修改部分 ---------------- 开始 */ entry: utils.entries(), /* 修改部分 ---------------- 结束 */ output: { path: config.build.assetsRoot, filename: '[name].js', publicPath: process.env.NODE_ENV === 'production' ? config.build.assetsPublicPath : config.dev.assetsPublicPath }, resolve: { extensions: ['.js', '.vue', '.json'], alias: { 'vue$': 'vue/dist/vue.esm.js', '@': resolve('src'), 'pages': resolve('src/pages'), 'components': resolve('src/components') } }, module: { rules: [{ test: /.vue$/, loader: 'vue-loader', options: vueLoaderConfig }, { test: /.js$/, loader: 'babel-loader', include: [resolve('src'), resolve('test')] }, { test: /.(png|jpe?g|gif|svg)(?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('img/[name].[hash:7].[ext]') } }, { test: /.(woff2?|eot|ttf|otf)(?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('fonts/[name].[hash:7].[ext]') } } ] } }
webpack.dev.conf.js 文件
var utils = require('./utils') var webpack = require('webpack') var config = require('../config') var merge = require('webpack-merge') var baseWebpackConfig = require('./webpack.base.conf') var HtmlWebpackPlugin = require('html-webpack-plugin') var FriendlyErrorsPlugin = require('friendly-errors-webpack-plugin') // add hot-reload related code to entry chunks Object.keys(baseWebpackConfig.entry).forEach(function (name) { baseWebpackConfig.entry[name] = ['./build/dev-client'].concat(baseWebpackConfig.entry[name]) }) 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 /* 注释这个区域的文件 ------------- 开始 */ // new HtmlWebpackPlugin({ // filename: 'index.html', // template: 'index.html', // inject: true // }), /* 注释这个区域的文件 ------------- 结束 */ new FriendlyErrorsPlugin() /* 添加 .concat(utils.htmlPlugin()) ------------------ */ ].concat(utils.htmlPlugin()) })
webpack.prod.conf.js 文件
var path = require('path') var utils = require('./utils') var webpack = require('webpack') var config = require('../config') var merge = require('webpack-merge') var baseWebpackConfig = require('./webpack.base.conf') var CopyWebpackPlugin = require('copy-webpack-plugin') var HtmlWebpackPlugin = require('html-webpack-plugin') var ExtractTextPlugin = require('extract-text-webpack-plugin') var OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin') var env = config.build.env var webpackConfig = merge(baseWebpackConfig, { module: { rules: utils.styleLoaders({ sourceMap: config.build.productionSourceMap, extract: true }) }, devtool: config.build.productionSourceMap ?

至此，webpack的配置就结束了。

src就是我所使用的工程文件了，assets,components,pages分别是静态资源文件、组件文件、页面文件。
原先，入口文件只有一个main.js,但现在由于是多页面，因此入口页面多了，我目前就是两个：index和cell，之后如果打包，就会在dist文件下生成两个HTML文件：index.html和cell.html(可以参考一下单页面应用时，打包只会生成一个index.html,区别在这里)。
页面跳转问题
既然是多页面，肯定涉及页面之间的互相跳转，就按照我这个项目举例，从index.html文件点击a标签跳转到cell.html。
一般都认为这样写：
<!-- index.html --> <a href='../cell/cell.html'></a>
但这样写，不论是在开发环境还是最后测试，都会报404，找不到这个页面。
改成这样既可：
<!-- index.html --> <a href='cell.html'></a>
如果想跳转到另外一个路由配置的某个模块，如账号中心，如下例子：
<a class="home_account" href="login.html#/inner/acount/acountCenter">{{userInfo.phone}}</a>
