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
