vue-cli + webpack自动生成项目

# 全局安装 vue-cli
$ npm install --global vue-cli
# 创建一个基于 webpack 模板的新项目
$ vue init webpack palanWebsite
# 安装依赖，走你
$ cd palanWebsite
$ npm install
$ npm run dev

创建过程参考：https://www.2cto.com/kf/201711/695061.html，单元测试选择的是jest

创建好的项目结构如下：

下面就重点分析build和config目录下各个配置文件的解析：

config目录下的各项配置都是为了服务webpack的配置，给不同的编译条件提供配置

config/index.js

'use strict'

const path = require('path')

module.exports = {
  dev: {

    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {},

    // Various Dev Server settings
    host: 'localhost', // can be overwritten by process.env.HOST
    port: 8080, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
    autoOpenBrowser: false,
    errorOverlay: true,
    notifyOnErrors: true,
    poll: false, 

    useEslint: true,
    showEslintErrorsInOverlay: false,

    /**
     * Source Maps
     */

    // https://webpack.js.org/configuration/devtool/#development
    devtool: 'cheap-module-eval-source-map',

    cacheBusting: true,

    cssSourceMap: true
  },

  build: {
    // 在任何模块文件内部，可以使用__dirname变量获取当前模块文件所在目录的完整绝对路径。
    index: path.resolve(__dirname, '../dist/index.html'),

    // Paths
    assetsRoot: path.resolve(__dirname, '../dist'),
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',

    /**
     * Source Maps
     */

    productionSourceMap: true,
    // https://webpack.js.org/configuration/devtool/#production
    devtool: '#source-map',

    productionGzip: false,
    productionGzipExtensions: ['js', 'css'],

    // Run the build command with an extra argument to
    // View the bundle analyzer report after build finishes:
    // `npm run build --report`
    // Set to `true` or `false` to always turn it on or off
    bundleAnalyzerReport: process.env.npm_config_report
  }
}
