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:
安装gulp
代码如下:
$ 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
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", "build-online": "gulp pack --env production", "deploy": "gulp deploy --env debug", "deploy-online": "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" } }
