webpack写jquery插件的环境配置分享

客户需求要一个具备树结构、带复选框的下拉选择控件；在网上找到了select2、autocomplete都不满足要求。于是自己用ztree加bootstrap dropdown组合开发了一个下拉树选择控件。决定用webpack打包，开发一个完整的jquery控件，顺便系统的学习一下webpack。

目录结构：

package.json配置：

{  "name": "select-tree",  "version": "0.0.1",  "description": "下拉树形选择，带复选框",  "license": "MIT",  "author": "kaikai",  "repository": "https://gitee.com/hkgit/select-tree",  "scripts": {   "start": "webpack --watch",   "build": "webpack --config webpack.config.js"  },  "dependencies": {   "jquery": "~1.12.4",   "bootstrap": "^3.3.7",   "jquery-slimscroll": "latest",   "ztree": "latest"  },  "devDependencies": {   "css-loader": "^0.28.7",   "html-webpack-plugin": "^2.30.1",   "style-loader": "^0.19.1",   "uglifyjs-webpack-plugin": "^1.1.4",   "webpack": "^3.10.0"  },  "bugs": {   "url": "https://gitee.com/hkgit/select-tree/issues"  },  "keywords": [   "javascript",   "select",   "tree",   "checkbox"  ] }

说明：jquery用1.12的版本是为了兼容IE9浏览器，开发环境用的webpack’s Watch Mode，由于项目比较小，调试就直接用chrome打开dist/select-tree.html文件。

webpack.config.js代码：

const path = require('path'); const webpack = require('webpack'); const HtmlWebpackPlugin = require('html-webpack-plugin'); const UglifyJSPlugin = require('uglifyjs-webpack-plugin');  module.exports = {   entry: {     vendor: ['jquery'], // 把需要引入的插件单独分出一个入口，和插件主体分开     main: './src/select-tree.js'   },   output: {     filename: 'select-tree-min.js',     path: path.resolve(__dirname, './dist'),     library: 'selectTree', // 插件名称     libraryTarget: 'umd' // 插件支持CommonJS2，CommonJS，amd，var   },   // resolve: { // npm下载的jquery不需要制定路径   //   modules: [path.join(__dirname, "node_modules")],   //   alias: {   //     jquery: 'jquery/dist/jquery.js'   //   }   // },   module: {     rules: [{       test: /.css$/,       use: ['style-loader', 'css-loader']     }]   },   plugins: [     new HtmlWebpackPlugin({ // 自动生成html       template: './src/select-tree.html',       filename: 'select-tree.html'     }),     new UglifyJSPlugin({ // 压缩代码       sourceMap: true     }),     new webpack.optimize.CommonsChunkPlugin({ // 单独打包jq插件，此插件的依赖库单独抽出来，不影响插件的开发       name: "vendor",       filename: "vendor.min.js"     }),     new webpack.ProvidePlugin({ // 自动加载jq       $: 'jquery',       jQuery: 'jquery'     })   ],   devtool: 'source-map' // 方便调试 };

说明：重点在output.library和output.libraryTarget
