vue中如何配置多页面配置

webpack 有个特性，基本的功能都是可以用配置去实现的，所以就造成一个特点“很容易忘记它”，所以就很有必要记录一下
简述一下
webpack 分为

• Entry：入口
• Output: 出口
• Module 模块
• Plugin 插件
• DevServer 服务器配置

const path = require('path')

const HtmlWebpackPlugin = require('html-webpack-plugin');
const merge = require('webpack-merge');
const glob = require('glob');
const pathSrc = path.resolve(__dirname, '../src');


// 指定开发模式下运行某模块；多个加载，可能会加载偏慢
/**
 * index: 个人中心；  active 活动； product 产品； policyManager 保单管理; all  有此字段为加载全部
 */
const devMolues = ['policyManager']

exports.getEntrys = function(suffix, polyfill) {
    // 自动获取
    let entryHtml = glob.sync(pathSrc + '/views/**/app.js');

    let entries = {};
    entryHtml.forEach((filePath) => {
        // views/product/app.html
        let _chunk = filePath.split(pathSrc.replace(/\\/g, '/'))[1];
        _chunk = _chunk.substring(0, _chunk.lastIndexOf('/'));
        _chunk = _chunk.substring(_chunk.lastIndexOf('/') + 1, _chunk.length);
        
        if (process.env.NODE_ENV !== 'production') {
            let flag = false;
            for (let item of devMolues) {
                if (item === _chunk || item === 'all') {
                    flag = true;
                }
            }

            if (flag) {
                if (suffix == 'html') {
                    entries[_chunk] = filePath.replace(/.js/g, '.html');
                }
                if (suffix == 'js') {
                    entries[_chunk] = filePath;
                } 
            }

        } else {
            if (suffix == 'html') {
                entries[_chunk] = filePath.replace(/.js/g, '.html');
            }
            if (suffix == 'js') {
                entries[_chunk] = filePath;
            }
        }
        
    })
    return entries;
}

exports.htmlPlugins = () => {
    let entryHtmls = this.getEntrys('html');
    let arrPull = [];
    for (let _chunk in entryHtmls) {
        let conf = {};
        if (process.env.NODE_ENV === 'production') {
            conf = {
                filename: _chunk + '.html',
                template: 'index.html', // entryHtmls[_chunk]  // 引入同一个文件
                inject: true,
                minify: {
                    removeComments: true,
                    collapseWhitespace: true,
                    removeAttributeQuotes: true
                        // more options:
                        // https://github.com/kangax/html-minifier#options-quick-reference
                },
                chunks: ['manifest', 'vendor', _chunk]
            }
        } else {
            conf = {
                filename: _chunk + '.html',
                template: 'index.html',
                inject: true,
                chunks: [_chunk]
            }
        }
        arrPull.push(new HtmlWebpackPlugin(conf));
    }
    return arrPull;
}

实现这个主要是整合了 HtmlWebpackPlugin插件， 这个插件是webpack，用来生成对应的html文件的

 plugins: [
        new webpack.DefinePlugin({
            'process.env': require('../config/dev.env')
        }),
        new webpack.HotModuleReplacementPlugin(),
        new webpack.NamedModulesPlugin(), // HMR shows correct file names in console on update.
        new webpack.NoEmitOnErrorsPlugin(),
        // https: //github.com/ampedandwired/html-webpack-plugin
        // new HtmlWebpackPlugin({
        //     filename: 'index.html',
        //     template: 'index.html',
        //     inject: true,
        //     chunks: ['app']
        // }),

        // copy custom static assets
        new CopyWebpackPlugin([{
            from: path.resolve(__dirname, '../static'),
            to: config.dev.assetsSubDirectory,
            ignore: ['.*']
        }])
    ].concat(mutiplePageConfig.htmlPlugins())
