"Exploring the Best Locations to Incorporate Plugins in VueJS Webpack

I am trying to incorporate Webpack provided Plugins in order to utilize JQuery globally. Some resources suggest

You should add it in the webpack.config.js file under plugins:[] section.

However, upon examining my webpack.config.js, I noticed that there is no such plugins object present. As a workaround, I manually created the plugins object within the module array.

When attempting to execute the project using npm run dev,

it fails to run. I specifically want to include this plugin in the webpack.config.js

new webpack.ProvidePlugin({
  $: 'jquery',
  jQuery: 'jquery'
})

Any tips on how to achieve this? Below is my current webpack.config.js file:

var path = require('path')
var webpack = require('webpack')

module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: '/dist/',
    filename: 'build.js'
  },
  module: {
    rules: [
      {
        test: /\.css$/,
        use: [
          'vue-style-loader',
          'css-loader'
        ],
      },      
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
          }
          // additional vue-loader configurations can be added here
        }
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /\.(png|jpg|gif|svg)$/,
        loader: 'file-loader',
        options: {
          name: '[name].[ext]?[hash]'
        }
      }
    ]
  },
  plugins: [
    new webpack.ProvidePlugin({
      $: 'jquery',
      jQuery: 'jquery'
    }),
    new webpack.ProvidePlugin({
      Vue: ['vue/dist/vue.esm.js', 'default']
    })
  ],
  resolve: {
    alias: {
      'vue$': 'vue/dist/vue.esm.js'
    },
    extensions: ['*', '.js', '.vue', '.json']
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true,
    overlay: true
  },
  performance: {
    hints: false
  },
  devtool: '#eval-source-map'
}

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      sourceMap: true,
      compress: {
        warnings: false
      }
    }),
    new webpack.LoaderOptionsPlugin({
      minimize: true
    })
  ])
}

Answer №1

When glancing at the webpack documentation regarding plugins here, it becomes clear where the plugins object should be placed.

The great news is that your webpack configuration appears to be correct - you have correctly positioned the plugins array as a direct child of the config, following module, rather than placing it inside. The only thing missing is a colon after plugins, which seems to be a minor typo.

Therefore, there doesn't seem to be any reason why it shouldn't work.

Answer №2

Make sure to add the following code snippet to both build/webpack.dev.conf.js and build/webpack.prod.conf.js:

plugins: [

  // ...

  new webpack.ProvidePlugin({
    $: 'jquery',
    jquery: 'jquery',
    'window.jQuery': 'jquery',
    jQuery: 'jquery'
  })
]

By including this, jQuery will be accessible globally across all your modules.
