JQuery with webpack 2

JQuery with webpack 2

My webpack.config.js looks like this:

var debug = process.env.NODE_ENV !== "production";
var webpack = require('webpack');
var path = require('path');
var node_dir = __dirname + '/node_modules';
const autoprefixer = require('autoprefixer');
const ProvidePlugin = require('webpack/lib/ProvidePlugin');

module.exports = {
  context: path.join(__dirname, "src"),
  devtool: debug ? "inline-sourcemap" : null,
  entry: ['tether',
    'font-awesome-loader',"bootstrap-loader","./js/client.js"],
  resolve: {
    extensions: ['.js', '.styl'],
    alias: {
      'jquery': node_dir + '/jquery/src/jquery.js',
    }
  },
  module: {
    rules: [
      {
        test: /\.jsx?$/,
        exclude: /(node_modules|bower_components)/,
        loader: 'babel-loader',
        query: {
          presets: ['react', 'es2015', 'stage-0'],
          plugins: ['react-html-attrs', 'transform-decorators-legacy', 'transform-class-properties'],
        }
      },
      { test: /\.css$/, use: ['style-loader', 'css-loader', 'postcss-loader'] },
      { test: /\.scss$/, use: ['style-loader', 'css-loader', 'postcss-loader', 'sass-loader'] },
      {
        test: /\.woff2?(\?v=[0-9]\.[0-9]\.[0-9])?$/,
        use: 'url-loader?limit=10000',
      },
      {
        test: /\.(ttf|eot|svg)(\?[\s\S]+)?$/,
        use: 'file-loader',
      },
      {
      test: /\.styl$/,
      use: [
        'style-loader',
        'css-loader',
        {
          loader: 'stylus-loader',
          /*options: {
            use: [stylus_plugin()],
          },*/
        },
      ],
    },
      // Use one of these to serve jQuery for Bootstrap scripts:

      // Bootstrap 4
      { test: /bootstrap\/dist\//, use: 'imports-loader?jQuery=jquery' },
    ]
  },
  output: {
    path: __dirname + "/dist/",
    filename: "client.min.js"
  },
  plugins:  [
    //new webpack.optimize.DedupePlugin(),
    //new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }),
    new webpack.ProvidePlugin({
      $: "jquery",
      jQuery: "jquery",
      "window.jQuery": "jquery",
      Tether: "tether",
      "window.Tether": "tether",
      Alert: "exports-loader?Alert!bootstrap/js/dist/alert",
      Button: "exports-loader?Button!bootstrap/js/dist/button",

  ],
};

    <script src="client.min.js"></script>
    
  </body>
</html>

Run code

But when I try to use the jQuery.timeago () function, I get below the error.

I followed the React By Example. When I print window.jQuery, I get some wierd numbers appearing after jQuery. But when I just type jQuery, I get undefined. When bootstrap 4 and $ .ajax () are running, I'm sure jQuery is on, but not sure why jQuery is showing unifined.

Can someone explain how to enable jQuery and what I am doing wrong.

Add the plugin to the plugin section of your configurator webpackas follows:

var webpack = require('webpack')
...

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

EDIT:

You have a circular dependency:

timeago: jquery
client: timeago jquery

jquery client - . include js bundles html :

<script src="client.min.js"></script>
<script src="jquery.timeago.js"></script>

:

<script src="jquery.timeago.js"></script>
<script src="client.min.js"></script>

, jquery timeago. - jquery, , , cdn, webpack , :

externals: {
  jquery: 'jQuery'
}

jquery timeago, :

<script src="common.js"></script>
<script src="jquery.timeago.js"></script>
<script src="client.min.js"></script>

chppppppppppppppp:

entry: {
  common: ["jquery"],
  ...
},
plugins: [
  new webpack.optimize.CommonsChunkPlugin({
    name: "common",
    filename: "common.js",
    minChunks: Infinity,
  })
],
