详解webpack+gulp实现自动构建部署

webpack系列目录

正文

本篇包含以下三点：

1.区分开发环境和生产环境

2.集成gulp

3.package.json 配置

前面主要介绍了webpack 的一些基础用法，该篇做一个整体介绍，如何集成gulp？如何应对多部署环境？

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：

1. 代码检查
2. clean操作
3. run webpack pack
4. 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

1. 启动webpack调试server： npm run server
2. 测试环境打包: npm run build
3. 生产环境打包: npm run build-online
4. 发布到测试环境: npm run deploy
5. 发布到生产环境: npm run deploy-online

完整package.json 如下：
