Quick Webpack Configuration

mix.webpackConfig({} || cb);

In some cases, it may prove easier to override the underlying webpack configuration directly.

As an example, perhaps you want to add a custom array of modules that should be automatically loaded by webpack.
We'll use Laravel Spark as an example:

    resolve: {
        modules: [
            path.resolve(__dirname, 'vendor/laravel/spark/resources/js')

The object passed to the webpackConfig() method will now be merged with Mix's generated config object.

Using a Callback Function

You may alternatively access webpack and all of its properties by passing a callback function.

mix.webpackConfig(webpack => {
    return {
        plugins: [
            new webpack.ProvidePlugin({
                $: 'jquery',
                jQuery: 'jquery',
                'window.jQuery': 'jquery'
