webpack写jquery插件的环境配置

时间:2017-12-26 编辑:猪哥 来源:一聚教程网

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
