webpack jquery插件加载自己的jquery实例

Question

我一直在尝试通过webpack加载一个jquery插件.此插件打包为npm模块,其依赖项仅包含jquery.我认为webpack加载了jquery的实例,而不是使用我提供的全局提供的ProvidePlugin.我尝试了另一个stackoverflow帖子中提供的所有解决方案(在webpack中管理jQuery插件依赖项),但他们没有成功; 结果总是一样的:"terminal()不是函数".如果我手动修改node_modules文件夹中的包,删除package.json中的jquery依赖项,并在node_modules插件文件夹中下载的依赖项webpack成功地将该插件与jquery的全局实例绑定.我知道,我可以简单地创建该包的一个分支并使用私有的npm存储库,但我想使用官方包.

这是我的webpack配置:

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var CleanWebpackPlugin = require('clean-webpack-plugin');
var CopyWebpackPlugin = require('copy-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var moment = require('moment');
var path = require('path');
var environment = process.env.APP_ENVIRONMENT || 'dev';

module.exports = {

  entry: {
    'app': './src/main.ts',
    'polyfills': './src/polyfills.ts',
    'vendor': './src/vendor.ts'
  },
  /*devtool: 'source-map',*/
  output: {
    path: './dist',
    filename: '[name].browser.' + moment().format('DDMMYYYYHHmm') + '.js'
  },
  module: {
    loaders: [
      { test: /\.component.ts$/, loader: 'ts!angular2-template' },
      { test: /\.ts$/, exclude: /\.component.ts$/, loader: 'ts' },
      { test: /\.html$/, loader: 'raw-loader' },
      { test: /\.css$/, include: path.resolve('src/app'), loader: 'raw-loader' },
      {
        test: /\.css$/, exclude: path.resolve('src/app'), loader: ExtractTextPlugin.extract('style', 'css', {
          fallbackLoader: "style-loader",
          loader: "css-loader"
        })
      },
      { test: /\.(png|jpe?g|gif|ico)$/, loader: 'file?name=fonts/[name].[ext]' },
      { test: /\.woff(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/font-woff&name=fonts/[name].[ext]" },
      { test: /\.woff2(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/font-woff&name=fonts/[name].[ext]" },
      { test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/octet-stream&name=fonts/[name].[ext]" },
      { test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: "file?name=fonts/[name].[ext]" },
      { test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=image/svg+xml&name=fonts/[name].[ext]" },
    ]
  },
  resolve: {
    extensions: ['', '.js', '.ts', '.html', '.css']
  },
  plugins: [
    new webpack.optimize.CommonsChunkPlugin({
      name: ['vendor', 'polyfills']
    }),
    new HtmlWebpackPlugin({
      template: './src/index.html'
    }),
    new webpack.DefinePlugin({
      app: {
        environment: JSON.stringify(environment),
        config: JSON.stringify(require('./profile/' + environment + ".profile.js"))
      }
    }),
    new CleanWebpackPlugin(
      ['dist']
    ),
    new CopyWebpackPlugin([
      { from: './src/images', to: 'images' }
    ]),
    new ExtractTextPlugin('[name].browser.css'),
    new webpack.optimize.UglifyJsPlugin({ minimize: true }),
    new webpack.ProvidePlugin({
      $: "jquery",
      jQuery: "jquery",
      "window.jQuery": "jquery"
    })
  ]
};

Answer 1

我通过稍微修改我的Webpack配置解决了我的问题.正如这里所建议的(在webpack中管理jQuery插件依赖),我添加了一个jquery别名.在提供的示例中,别名是静态指定的,它对我不起作用.我切换到动态值,这解决了问题.

这是片段:

alias: {
      'jquery': path.resolve(path.join(__dirname, 'node_modules', 'jquery'))
     },

Answer 2

不熟悉 jquery.terminal，但明确告诉插件如何加载 jQuery 可能会有所帮助。我不得不对几个类似问题的插件执行此操作。

    loaders: [{
        test: /jquery.terminal.+\.(js)$/,
        loader: 'imports?jQuery=jquery,$=jquery,this=>window'
    }]
