webpack+gulp实现自动构建部署

责编:menVScode 2018-03-12 13:36 阅读(903)


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?

项目结构说明

    ├── webpack.config.js         # 正式环境webpack配置入口
    └── 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:

(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:

{
      "name": "webpack-avalon",
      "version": "1.0.0",
      "description": "",
      "main": "index.js",

        "deploy": "gulp deploy --env debug",
        "deploy-online": "gulp deploy --env production"
      },

        "jshint": "^2.9.2",
        "jshint-stylish": "^2.2.0",
        "jsx-loader": "^0.13.2",
        "minimist": "^1.2.0",
        "node-sass": "^3.7.0",
