Occasionally, you may need to manually modify the underlying Webpack configuration. For example, you might have a special loader or plugin that needs to be referenced.
Mix provides a useful webpackConfig method that allows you to merge any short Webpack configuration overrides. This is particularly appealing, as it doesn't require you to copy and maintain your own copy of the webpack.config.js file. The webpackConfig method accepts an object, which should contain any Webpack-specific configuration that you wish to apply.
