一：区分 dev环境 和 生产环境

重命名 webpack.config.js => webpack.config.allinone.js

内容上，新增options参数，利用options.debug 来控制webpack参数，用来区分开发和生产环境。例如开发环境不需要混淆和压缩js文件，但是开发环境需要。通过option.debug来区分选择相应的loader配置和Plugin：

module.exports = function(options){ options = options || {} var debug = options.debug !==undefined ? options.debug :true; ...... if(debug){ // }else{ // }

新增webpack.config.js webpack-dev.config.js

//webpack.config.js 'use strict'; var webpack_config = require('./webpack.config.allinone') module.exports = webpack_config({debug:false}) //webpack-dev.config.js 'use strict'; var webpack_config = require('./webpack.config.allinone') module.exports = webpack_config({debug:true})

后续可以根据gulp 指令 动态选择 是开发环境还是测试环境，具体见gulpfile.js

//用于gulp传递参数 var minimist = require('minimist'); var knownOptions = { string: 'env', default: {env: process.env.NODE_ENV || 'production'} }; var options = minimist(process.argv.slice(2), knownOptions); var webpackConf = require('./webpack.config'); var webpackConfDev = require('./webpack-dev.config'); var _conf = options.env === 'production' ? webpackConf : webpackConfDev; webpack(_conf, function (err, stats) {......

二：集成gulp

利用 gulp 完成以下工作：

• 代码检查
• clean操作
• run webpack pack
• deploy 发布

安装gulp

$ npm install gulp gulp-clean jshint gulp-jshint jshint-stylish gulp-sftp gulp-util minimist --save-dev

新增gulpfile.js

完整gulpfile.js 如下：

/** * Created by sloong on 2016/6/14. */ 'use strict'; var gulp = require('gulp'); var webpack = require('webpack'); //用于gulp传递参数 var minimist = require('minimist'); var gutil = require('gulp-util'); var src = process.cwd() + '/src'; var assets = process.cwd() + '/dist'; var knownOptions = { string: 'env', default: {env: process.env.NODE_ENV || 'production'} }; var options = minimist(process.argv.slice(2), knownOptions); var webpackConf = require('./webpack.config'); var webpackConfDev = require('./webpack-dev.config'); var remoteServer = { host: '192.168.56.129', remotePath: '/data/website/website1', user: 'root', pass: 'password' }; var localServer = { host: '192.168.56.130', remotePath: '/data/website/website1', user: 'root', pass: 'password' } //check code gulp.task('hint', function () { var jshint = require('gulp-jshint') var stylish = require('jshint-stylish') return gulp.src([ '!' + src + '/js/lib/**/*.js', src + '/js/**/*.js' ]) .pipe(jshint()) .pipe(jshint.reporter(stylish)); }) // clean asserts gulp.task('clean', ['hint'], function () { var clean = require('gulp-clean'); return gulp.src(assets, {read: true}).pipe(clean()) }); //run webpack pack gulp.task('pack', ['clean'], function (done) { var _conf = options.env === 'production' ? webpackConf : webpackConfDev; webpack(_conf, function (err, stats) { if (err) throw new gutil.PluginError('webpack', err) gutil.log('[webpack]', stats.toString({colors: true})) done() }); }); //default task gulp.task('default', ['pack']) //deploy assets to remote server gulp.task('deploy', function () { var sftp = require('gulp-sftp'); var _conf = options.env === 'production' ? remoteServer : localServer; return gulp.src(assets + '/**') .pipe(sftp(_conf)) })

三：package.json 配置

scripts 配置 各个指令

• 启动webpack调试server： npm server
• 测试环境打包: npm build
• 生产环境打包: npm buildP
• 发布到测试环境: npm deploy
• 发布到生产环境: npm deployP

完整package.json 如下：

    { "name": "webpack-avalon", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "server": "webpack-dev-server --inline", "build": "gulp pack --env debug", "buildP": "gulp pack --env production", "deploy": "gulp deploy --env debug", "deployP": "gulp deploy --env production" }, "author": "sloong", "license": "MIT", "devDependencies": { "css-loader": "^0.21.0", "ejs-loader": "^0.3.0", "extract-text-webpack-plugin": "^1.0.1", "file-loader": "^0.8.5", "gulp": "^3.9.1", "gulp-clean": "^0.3.2", "gulp-jshint": "^2.0.1", "gulp-sftp": "^0.1.5", "gulp-util": "^3.0.7", "html-loader": "^0.4.3", "html-webpack-plugin": "^2.19.0", "jshint": "^2.9.2", "jshint-stylish": "^2.2.0", "jsx-loader": "^0.13.2", "minimist": "^1.2.0", "node-sass": "^3.7.0", "sass-loader": "^3.2.0", "style-loader": "^0.13.0", "url-loader": "^0.5.7", "webpack": "^1.13.1", "webpack-dev-server": "^1.14.1" } }

## 开发要求 ##

 

约定/src/*.html为应用的入口文件，在/src/js/ 一级目录下需有一个同名的js文件作为该文件的入口。

 

## 编译（测试/dev环境） ##

 

    $ npm run build

 

## 编译（生产环境） ##

 

生产环境会对js混淆压缩，对css、html进行压缩，字符替换等处理

 

    $ npm run buildP

 

## 部署发布 ##

 

在gulpfile.js 中配置好localServer和remoteServer，编译后将dist目录发布到服务端

 

发布到localServer

 

    $ npm run deploy

 

发布到remoteServer

 

    $ npm run deployP

 

## 本地调试 ##

 

    $ npm run server

    # 或者 下面两种模式

    $ webpack-dev-server

    $ webpack-dev-server --inline

 

## Jenkins 持续集成 ##

 

    需要nodejs

    $ npm run buildP

    $ npm run deployP
