jQuery Question

Error: Bootstrap's JavaScript requires jQuery, using Webpack

I'm new to webpack, but I started using 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 bootstrap library after 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'

new webpack.ProvidePlugin({

new webpack.optimize.CommonsChunkPlugin('vendors', 'vendors.js', Infinity)

Answer Source

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


so finally the plugin looks like this:

 new webpack.ProvidePlugin({
  $: "jquery",
  jquery: "jquery",
  "windows.jQuery": "jquery",

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