This time I will show you how to use webpack to write the jquery environment configuration. What are the precautions for using webpack to write the jquery environment configuration? The following is a practical case, let's take a look.

The customer needs a drop-down selection control with a tree structure and check boxes; I found select2 and autocomplete on the Internet, but neither of them met the requirements. So I developed a drop-down tree selection control using a combination of ztree and bootstrap dropdown. I decided to use webpack for packaging, develop a complete jquery control, and learn webpack systematically.

Directory structure :

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"

Description: jquery version 1.12 is In order to be compatible with the IE9 browser, webpack's Watch Mode is used in the development environment. Since the project is relatively small, the dist/select-tree.html file is directly opened in chrome for debugging.

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
};
