    └── webpack-dev.config.js     # 开发环境webpack配置入口

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",

        "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
