webpack写jquery插件的环境配置

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：

rush:xhtml;"> { "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：

rush:xhtml;"> 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
