This time I will show you how to configure webpack with jquery. What are the precautions for configuring webpack with jquery? The following is a practical case, let’s take a look.

The customer needs a drop-down selection control with a tree structure and a

checkbox; I found select2 and autocomplete on the Internet, but neither of them met the requirements. So I used ztree and added bootstrap The dropdown combination develops a drop-down tree selection control. I decided to use webpack for packaging, develop a complete jquery control, and learn webpack systematically.

package.json configuration:

{
 "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"
 ]
}
Note: jquery uses version 1.12 to be compatible with IE9 browsers, and webpack's Watch Mode is used in the development environment. Since the project is relatively small, for debugging, just use chrome to open the dist/select-tree.html file directly.

webpack.config.js code:

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
};
Note: The focus is on output.library and output.libraryTarget
