The $ variable in jQuery is typically created by the jQuery library itself, but when using webpack, the $ variable may show up as undefined if jQuery is not properly loaded or if there are conflicts with other JavaScript libraries.


To resolve this issue, make sure that you are loading jQuery before any other JavaScript code that relies on it. You can also try using the webpack ProvidePlugin to automatically load jQuery and make it available in all modules.


You can add the ProvidePlugin to your webpack configuration like this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
const webpack = require('webpack');

module.exports = {
  // other webpack configuration options
  plugins: [
    new webpack.ProvidePlugin({
      $: 'jquery',
      jQuery: 'jquery'
    })
  ]
};


This will ensure that the $ variable is properly defined and available for use in your webpack modules.
