Error: Bootstrap's JavaScript requires jQuery, using Webpack

I'm new to webpack, but I started using it in one of my projects to learn about it.

I would like to use jQuery with Bootstrap, however, when I launch the app, I'm getting the following error:

bootstrap.min.js?5802:6Uncaught Error: Bootstrap's JavaScript requires jQuery

In my webpack config, I have defined two entry points, one for libraries of the project and one for the external ones, called vendors, like jQuery, Bootstrap, etc.

In vendors, I have defined the Bootstrap library after the jQuery library, but I cannot get rid of the error. Any clues of what I'm missing?

This is my webapp config:

import webpack from 'webpack';
import HtmlWebpackPlugin from 'html-webpack-plugin';
import autoprefixer from 'autoprefixer';
let node_dir = __dirname + '/node_modules';

export default {
  resolve: {
    extensions: ['', '.js', '.jsx'],
    alias: {
      'jquery': node_dir + '/jquery/dist/jquery.js',
      'jquery-validation': node_dir + '/jquery-validation/dist/jquery.validate.js',
      'bootstrap': node_dir + '/bootstrap/dist/js/bootstrap.min.js'
    }
  },
  debug: true,
  devtool: 'cheap-module-eval-source-map', // more info:https://webpack.github.io/docs/build-performance.html#sourcemaps and https://webpack.github.io/docs/configuration.html#devtool
  noInfo: true, // set to false to see a list of every file being bundled.

  entry: {
    // must be first entry to properly set public path
    app: ['./src/webpack-public-path',
      'webpack-hot-middleware/client?reload=true',
      './src/index'],
    vendors: ['jquery','jquery-validation','bootstrap']
  },
  target: 'web', // necessary per https://webpack.github.io/docs/testing.html#compile-and-test
  output: {
    path: `${__dirname}/src`, // Note: Physical files are only output by the production build task `npm run build`.
    publicPath: '/',
    filename: 'bundle.js'
  },
  plugins: [
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify('development'), // Tells React to build in either dev or prod modes. https://facebook.github.io/react/downloads.html (See bottom)
      __DEV__: true
    }),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin(),
    new HtmlWebpackPlugin({     // Create HTML file that includes references to bundled CSS and JS.
                                //template: 'src/index.ejs',
      template: 'src/index.html',
      minify: {
        removeComments: true,
        collapseWhitespace: true
      },
      inject: true
    }),
    new webpack.ProvidePlugin({
      $: "jquery",
      jquery: "jquery",
      "windows.jQuery": "jquery"
    }),
    new webpack.optimize.CommonsChunkPlugin('vendors', 'vendors.js', Infinity)
  ],
  module: {
    loaders: [
      {test: /\.jsx?$/, exclude: /node_modules/, loaders: ['babel']},
      {test: /\.eot(\?v=\d+.\d+.\d+)?$/, loader: 'file'},
      {test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/, loader: "url?limit=10000&mimetype=application/font-woff"},
      {test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=application/octet-stream'},
      {test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=image/svg+xml'},
      {test: /\.(jpe?g|png|gif)$/i, loader: 'file?name=[name].[ext]'},
      {test: /\.ico$/, loader: 'file?name=[name].[ext]'},
      {test: /(\.css|\.scss)$/, loaders: ['style', 'css?sourceMap', 'postcss', 'sass?sourceMap']}
    ]
  },
  postcss: ()=> [autoprefixer]
};

I finally got rid of the error just by adding a new entry in the ProvidePlugin:

 jQuery:"jquery"

so finally the plugin looks like this:

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

I leave it here in case someone else faces the same problem.

Bootstrap requires jquery to be available on the global object. Try the below -

import 'bootstrap/dist/css/bootstrap.min.css';

const $ = require('jquery');
window.$ = $;
window.jQuery = $;
require('bootstrap/dist/js/bootstrap.min');

Ref - issue
