vue官方vue-cli构建的vue项目结构分析
一、概要
vue现在在很多公司会大量使用,研究一下vue-cli脚手架构建项目的项目结构,有助于理解vue。
博客首发地址:https://www.mwcxs.top/page/570.html
使用vue-cli脚手架搭建vue项目的具体步骤如下:
npm install -g vue-cli
cd E:(跳转到项目目录)
vue init webpack vueproject (vueproject 为项目目录名称,可行更改)
cd vueproject
npm install
npm run dev
二、具体分析
2.1package.json文件
1、script字段
"scripts": {
"dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
"start": "npm run dev",
"unit": "jest --config test/unit/jest.conf.js --coverage",
"e2e": "node test/e2e/runner.js",
"test": "npm run unit && npm run e2e",
"lint": "eslint --ext .js,.vue src test/unit test/e2e/specs",
"build": "node build/build.js"
},
项目开发周期主要执行的两个任务分别是开发环境npm run dev
和打包任务npm run build,
script字段是用来指定npm相关命令的缩写的
npm run dev 其实执行的是
webpack-dev-server --inline --progress --config build/webpack.dev.conf.js
利用 webpack-dev-server 读取 webpack.dev.conf.js 信息并启动一个本地服务器,这应该也是新版本vue-cli的新特性。
以前老的项目是使用node的express开启一个本地服务器。
2、dependencies和devDependencies字段
dependencies字段指定了项目运行时所依赖的模块;
devDependencies字段是指定了项目开发时候所依赖的模块。
项目开发应使用的命令管理package.json文件:
npm i --save vue //自动写入到dependencies字段中
npm i --save-dev babel-core //自动写入到devDependencies字段
3、engines和browerslist字段
"engines": {
"node": ">= 6.0.0",
"npm": ">= 3.0.0"
},
"browserslist": [
"> 1%",
"last 2 versions",
"not ie <= 8"
]
engines字段表示项目运行的所依赖的node以及npm的版本号;
browserslist表示项目的浏览器支持情况。
2.2build文件夹
1、基础配置文件 webpack.base.conf.js
基础的webpack配置文件主要根据模式(开发,线上等)定义了入口和出口,以及处理vue,babel等的各种模块,是最基础的部分。其他模式(开发,线上等)的配置文件是以base为基础通过webpack-merge合并的。
'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
function resolve (dir) { //处理路径
return path.join(__dirname, '..', dir)
}
const createLintingRule = () => ({ //Eslint检查规则
test: /\.(js|vue)$/,
loader: 'eslint-loader',
enforce: 'pre',
include: [resolve('src'), resolve('test')],
options: {
formatter: require('eslint-friendly-formatter'),
emitWarning: !config.dev.showEslintErrorsInOverlay
}
})
module.exports = {
context: path.resolve(__dirname, '../'), //基础目录
entry: {
app: './src/main.js' //入口文件
},
output: {
path: config.build.assetsRoot, //输出文件,默认为../dist
filename: '[name].js', //输出文件名称
publicPath: process.env.NODE_ENV === 'production'
? config.build.assetsPublicPath //生成模式publicpath
: config.dev.assetsPublicPath //开发模式
},
resolve: { //解析确定的扩展名,方便模块导入
extensions: ['.js', '.vue', '.json'],
alias: { //创建别名
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'), //如‘@/components/helloWorld’
}
},
module: { //模块相关配置,包括loader,plugin等
rules: [
...(config.dev.useEslint ? [createLintingRule()] : []),
{
test: /\.vue$/, //vue要在babel之前
loader: 'vue-loader', //vue转成普通的html
options: vueLoaderConfig //可选项:vue-loader选项配置
},
{
test: /\.js$/, //babel
loader: 'babel-loader', //es6转es5 的loader
include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')]
},
{ //url-loader 文件大小低于指定的限制时,可返回DataURL,即base64
test: /\.(png|jpe?g|gif|svg)(\?.*)?$/, //url-loader图片
loader: 'url-loader',
options: { //兼容性问题需要将query换成options
limit: 10000, //默认没有限制
name: utils.assetsPath('img/[name].[hash:7].[ext]') //hash: 7da代表7位数的hash
}
},
{
test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/, //url-loader音视频
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('media/[name].[hash:7].[ext]')
}
},
{
test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/, //url-loader 字体
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
}
}
]
},
node: { //是否polyfill或mock
// prevent webpack from injecting useless setImmediate polyfill because Vue
// source contains it (although only uses it if it's native).
setImmediate: false,
// prevent webpack from injecting mocks to Node native modules
// that does not make sense for the client
dgram: 'empty',
fs: 'empty',
net: 'empty',
tls: 'empty',
child_process: 'empty'
}
}
webpack.base.conf.js主要完成了下面这些事情:
(1)配置webpack编译入口
(2)配置webpack输出路径和命名规则
(3)配置模块resolve规则
(4)配置不同类型模块的处理规则
注:这个配置里面只配置了.js、.vue、图片、字体等文件的处理规则,如果需要处理其他文件可以在module.rules里面配置
2、开发环境配置文件 webpack.dev.conf.js
在启动项目的时候就要用到这个文件,说明这个文件比较重要
'use strict'
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config') //基本参数配置
const merge = require('webpack-merge') //用于合并webpack的base配置
const path = require('path')
const baseWebpackConfig = require('./webpack.base.conf') //webpack基本配置文件(开发时和运行时公用)
const CopyWebpackPlugin = require('copy-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin') //依据一个简单的模板,帮你生成最终的html文件,这个文件中自动引用你打包之后的js文件,每次编译都会插入一个不同的哈希值
const FriendlyErrorsPlugin = require('friendly-errors-webpack-plugin') //能够更好的在终端看到webpack运行的警告和错误
const portfinder = require('portfinder') //自动检索下一个可用端口
const HOST = process.env.HOST //读取系统环境变量的host
const PORT = process.env.PORT && Number(process.env.PORT) //读取系统环境变量的port
const devWebpackConfig = merge(baseWebpackConfig, { //合并baseWebpackConfig配置
module: {
rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap, usePostCSS: true }) //对一些独立的css文件以及他的预处理做一个编译
},
// cheap-module-eval-source-map is faster for development
devtool: config.dev.devtool, //添加原信息增强调试
// these devServer options should be customized in /config/index.js
devServer: { //webpack-dev-server服务器配置
clientLogLevel: 'warning', //console控制台显示消息,可能的值有none,error,warning,info
historyApiFallback: {
rewrites: [
{ from: /.*/, to: path.posix.join(config.dev.assetsPublicPath, 'index.html') },
],
},
hot: true, //开启热加载
contentBase: false, // since we use CopyWebpackPlugin.
compress: true, //开启压缩
host: HOST || config.dev.host, //process.env优先
port: PORT || config.dev.port, //process.env优先
open: config.dev.autoOpenBrowser, //自动打开浏览器,这里默认是false
overlay: config.dev.errorOverlay //warning和error都要显示
? { warnings: false, errors: true }
: false,
publicPath: config.dev.assetsPublicPath,
proxy: config.dev.proxyTable, //代理设置,用于前后端分离
quiet: true, // necessary for FriendlyErrorsPlugin
watchOptions: { //启用watch模式,这意味着初始构建之后,webpack将继续监听任何已解析文件的更改
poll: config.dev.poll, //通过传递true开启polling,或者指定毫秒为单位进行轮询,默认为false
}
},
plugins: [ //webpack一些构建用到的插件
new webpack.DefinePlugin({
'process.env': require('../config/dev.env')
}),
new webpack.HotModuleReplacementPlugin(), //模块热更新,它允许在运行的时候更新各个模块,而无需进行完全的刷新
new webpack.NamedModulesPlugin(),
//热加载的时候直接返回更新的文件名,而不是id HMR shows correct file names in console on update. new webpack.NoEmitOnErrorsPlugin(), //跳过热编译是出错的代码并记录下来,主要作用是编译后运行的时候包不出错
// https://github.com/ampedandwired/html-webpack-plugin
new HtmlWebpackPlugin({
filename: 'index.html', //指定编译后生成的html文件名
template: 'index.html', //需要处理的模板
inject: true //打包过程中的输出js,css的路径添加到html中,css文件插入到head中,js文件插入到body中,可能的选项有true,‘head’,‘body’,false
}),
// copy custom static assets
new CopyWebpackPlugin([ //拷贝静态文档
{
from: path.resolve(__dirname, '../static'),
to: config.dev.assetsSubDirectory,
ignore: ['.*']
}
])
]
})
module.exports = new Promise((resolve, reject) => {
portfinder.basePort = process.env.PORT || config.dev.port //获取当前设定的端口
portfinder.getPort((err, port) => {
if (err) {
reject(err)
} else {
// publish the new Port, necessary for e2e tests
process.env.PORT = port //process发布的端口
// add port to devServer config
devWebpackConfig.devServer.port = port //设置devserver端口
// Add FriendlyErrorsPlugin
devWebpackConfig.plugins.push(new FriendlyErrorsPlugin({ //错误提示插件
compilationSuccessInfo: {
messages: [`Your application is running here: http://${devWebpackConfig.devServer.host}:${port}`],
},
onErrors: config.dev.notifyOnErrors
? utils.createNotifierCallback()
: undefined
}))
resolve(devWebpackConfig)
}
})
})
该文件主要完成的事情:
(1)将hot-reload相关代码添加到entry chunks
(2)合并基础的webpack配置
(3)使用styleLoaders
(4)配置Source Maps
(5)配置webpack插件
3、生产模式配置文件 webpack.prod.conf.js
'use strict'
const path = require('path')
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')
const baseWebpackConfig = require('./webpack.base.conf')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin')
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')
const env = process.env.NODE_ENV === 'testing'
? require('../config/test.env')
: require('../config/prod.env')
const webpackConfig = merge(baseWebpackConfig, {
module: {
rules: utils.styleLoaders({
sourceMap: config.build.productionSourceMap, //production下生成sourceMap
extract: true, //util中styleLoader方法内的generateLoaders函数
usePostCSS: true //默认使用postcss
})
},
devtool: config.build.productionSourceMap ? config.build.devtool : false,
output: {
path: config.build.assetsRoot,
filename: utils.assetsPath('js/[name].[chunkhash].js'),
chunkFilename: utils.assetsPath('js/[id].[chunkhash].js')
},
plugins: [
// http://vuejs.github.io/vue-loader/en/workflow/production.html
new webpack.DefinePlugin({
'process.env': env
}),
new UglifyJsPlugin({ //js代码压缩还可以配置include,cache等,也可以使用babel-minify
uglifyOptions: {
compress: {
warnings: false
}
},
sourceMap: config.build.productionSourceMap,
parallel: true //充分利用多核cpu
}),
// extract css into its own file
new ExtractTextPlugin({ //提取js文件中的css
filename: utils.assetsPath('css/[name].[contenthash].css'),
// Setting the following option to `false` will not extract CSS from codesplit chunks.
// Their CSS will instead be inserted dynamically with style-loader when the codesplit chunk has been loaded by webpack.
// It's currently set to `true` because we are seeing that sourcemaps are included in the codesplit bundle as well when it's `false`,
// increasing file size: https://github.com/vuejs-templates/webpack/issues/1110
allChunks: true,
}),
// Compress extracted CSS. We are using this plugin so that possible
// duplicated CSS from different components can be deduped.
new OptimizeCSSPlugin({ //压缩提取出来的css
cssProcessorOptions: config.build.productionSourceMap
? { safe: true, map: { inline: false } }
: { safe: true }
}),
// generate dist index.html with correct asset hash for caching.
// you can customize output by editing /index.html
// see https://github.com/ampedandwired/html-webpack-plugin
new HtmlWebpackPlugin({ //生成html
filename: process.env.NODE_ENV === 'testing'
? 'index.html'
: config.build.index,
template: 'index.html',
inject: true,
minify: {
removeComments: true,
collapseWhitespace: true,
removeAttributeQuotes: true
// more options:
// https://github.com/kangax/html-minifier#options-quick-reference
},
// necessary to consistently work with multiple chunks via CommonsChunkPlugin
chunksSortMode: 'dependency' //按照dependency的顺序引入
}),
// keep module.id stable when vendor modules does not change
new webpack.HashedModuleIdsPlugin(), //根据模块的相对路径生成一个四位数的hash
// enable scope hoisting
new webpack.optimize.ModuleConcatenationPlugin(), //预编译所有的模块到一个闭包中
// split vendor js into its own file
new webpack.optimize.CommonsChunkPlugin({ //拆分公共模块
name: 'vendor',
minChunks (module) {
// any required modules inside node_modules are extracted to vendor
return (
module.resource &&
/\.js$/.test(module.resource) &&
module.resource.indexOf(
path.join(__dirname, '../node_modules')
) === 0
)
}
}),
// extract webpack runtime and module manifest to its own file in order to
// prevent vendor hash from being updated whenever app bundle is updated
new webpack.optimize.CommonsChunkPlugin({
name: 'manifest',
minChunks: Infinity
}),
// This instance extracts shared chunks from code splitted chunks and bundles them
// in a separate chunk, similar to the vendor chunk
// see: https://webpack.js.org/plugins/commons-chunk-plugin/#extra-async-commons-chunk
new webpack.optimize.CommonsChunkPlugin({
name: 'app',
async: 'vendor-async',
children: true,
minChunks: 3
}),
// copy custom static assets
new CopyWebpackPlugin([ //拷贝静态文档
{
from: path.resolve(__dirname, '../static'),
to: config.build.assetsSubDirectory,
ignore: ['.*']
}
])
]
})
if (config.build.productionGzip) { //开启gzip压缩
const CompressionWebpackPlugin = require('compression-webpack-plugin')
webpackConfig.plugins.push(
new CompressionWebpackPlugin({
asset: '[path].gz[query]',
algorithm: 'gzip',
test: new RegExp(
'\\.(' +
config.build.productionGzipExtensions.join('|') +
')$'
),
threshold: 10240, //10kb以上的文件才压缩
minRatio: 0.8 //最小比例达到0.8时才压缩
})
)
}
if (config.build.bundleAnalyzerReport) { //可视化分析包的尺寸
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin
webpackConfig.plugins.push(new BundleAnalyzerPlugin())
}
module.exports = webpackConfig
该文件的主要用处:
(1)合并基础的webpack.base.conf.js文件配置
(2)使用styleLoader
(3)配置webpack的输出路径
(4)配置webpack插件
(5)gzip模式下的webpack插件配置
(6)webpack-bundle分析
注:
webpack插件里面使用了压缩代码以及抽离css文件等插件
4、build.js 编译入口
'use strict'
require('./check-versions')()
process.env.NODE_ENV = 'production' //设置当前环境为生产环境
const ora = require('ora') //loading进度条
const rm = require('rimraf') //删除文件 rm -rf
const path = require('path')
const chalk = require('chalk') //stdout颜色设置
const webpack = require('webpack')
const config = require('../config')
const webpackConfig = require('./webpack.prod.conf')
const spinner = ora('building for production...')
spinner.start()
rm(path.join(config.build.assetsRoot, config.build.assetsSubDirectory), err => { //清空文件夹
if (err) throw err
webpack(webpackConfig, (err, stats) => { //删除完成回调函数内执行编译
spinner.stop()
if (err) throw err
process.stdout.write(stats.toString({ //编译完成,输出编译文件
colors: true,
modules: false,
children: false, // If you are using ts-loader, setting this to true will make TypeScript errors show up during build.
chunks: false,
chunkModules: false
}) + '\n\n')
if (stats.hasErrors()) { //error
console.log(chalk.red(' Build failed with errors.\n'))
process.exit(1)
}
console.log(chalk.cyan(' Build complete.\n')) //完成
console.log(chalk.yellow(
' Tip: built files are meant to be served over an HTTP server.\n' +
' Opening index.html over file:// won\'t work.\n'
))
})
})
build.js主要作用为:
(1)显示打包的loading动画
(2)删除并创建目标文件夹
(3)webpack编译源文件
(4)输出打包后的文件
注:webpack编译后会输出到配置里面的目标文件夹;删除目标文件夹之后再创建是为了去除旧的内容,以免产生不可预测的影响
5、实用代码段utils.js
'use strict'
const path = require('path')
const config = require('../config')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const packageConfig = require('../package.json')
exports.assetsPath = function (_path) {
const assetsSubDirectory = process.env.NODE_ENV === 'production'
? config.build.assetsSubDirectory //static
: config.dev.assetsSubDirectory
return path.posix.join(assetsSubDirectory, _path) //posix方法修正路径
}
exports.cssLoaders = function (options) {
options = options || {}
const cssLoader = { //csssloader
loader: 'css-loader',
options: {
sourceMap: options.sourceMap
}
}
const postcssLoader = { //postcssloader
loader: 'postcss-loader',
options: {
sourceMap: options.sourceMap
}
}
// generate loader string to be used with extract text plugin
function generateLoaders (loader, loaderOptions) { //生成loader
const loaders = options.usePostCSS ? [cssLoader, postcssLoader] : [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) { //生产模式中提取css
return ExtractTextPlugin.extract({ //如果options的extract为true配合生成模式
use: loaders,
fallback: 'vue-style-loader' //默认使用vue-style-loader
})
} else {
return ['vue-style-loader'].concat(loaders)
}
}
// https://vue-loader.vuejs.org/en/configurations/extract-css.html
return { //返回各种loaders对象
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) {
const output = []
const loaders = exports.cssLoaders(options)
for (const extension in loaders) {
const loader = loaders[extension]
output.push({
test: new RegExp('\\.' + extension + '$'),
use: loader
})
}
return output
}
exports.createNotifierCallback = () => { //配合friendly-errors-webpack-plugin
const notifier = require('node-notifier') //发送跨平台通知系统
return (severity, errors) => { //当前设定是只有出现error错误时触发notifier发送通知
if (severity !== 'error') return //严重程度可以是error或者warning
const error = errors[0]
const filename = error.file && error.file.split('!').pop()
notifier.notify({
title: packageConfig.name,
message: severity + ': ' + error.name,
subtitle: filename || '',
icon: path.join(__dirname, 'logo.png')
})
}
}
2.3config文件夹
1、index.js
'use strict'
// Template version: 1.3.1
// see http://vuejs-templates.github.io/webpack for documentation.
const path = require('path') //使用nodejs自带的文件路径插件
module.exports = {

}
}
该文件配置了开发和生产两种环境下的配置。
2.4babel配置文件

2.7src/app.vue文件解读
<template>
<div id="app">
<img src="./assets/logo.png">
<router-view/>
</div>
</template>
<script>
export default {
name: 'App'
}
</script>
<style>
#app {
font-family: 'Avenir', Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
margin-top: 60px;
}
</style>
<template>标签包裹的内容:这是模板的htmlDom的结构
<script>标签包括的js内容:可以在这里写一些页面的js逻辑代码
<style>标签包裹的css内容:页面需要的css样式
2.8src/router/index.js 路由文件
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
Vue.use(Router)
export default new Router({
routes: [ //配置路由
{
path: '/', //访问路径
name: 'HelloWorld', //路由名称
component: HelloWorld //路由需要的组件
}
]
})
vue-router具体可以看官方的文档:http://router.vuejs.org/
