How to replace smart function when a specific loader in a chain needs to be overriden?

The following works in webpack-merge 4.2.2, but the smart function has been removed. What I want is to override the configuration of the css-loader.

const base = {
        module: {
            rules: [
                {
                    test: /\.scss$/,
                    loaders: [
                        {
                            loader: MiniCssExtractPlugin.loader
                        },
                        {
                            loader: 'css-loader'
                        },
                        {
                            loader: 'postcss-loader',
                            options: {
                                plugins: function () {
                                    return [
                                        projectRequire('autoprefixer')
                                    ];
                                }
                            }
                        },
                        {
                            loader: 'resolve-url-loader'
                        },
                        {
                            loader: 'sass-loader',
                            options: {
                                sourceMap: true
                            }
                        }
                    ]
                }
            ]
        }
    }

    const development = {
        module: {
            rules: [
                {
                    test: /\.scss$/,
                    loaders: [
                        {
                            loader: 'css-loader',
                            options: {
                                sourceMap: true
                            }
                        }
                    ]
                }
            ]
        }
    }

@TorRanfelt I played around with the implementation. Here’s the proposed API: https://github.com/survivejs/webpack-merge/issues/146#issuecomment-698992119 .

mergeWithCustomize({
  customizeArray: customizeArray({
    "module.rules[test].loaders": CustomizeRule.Replace
  })
})

It’s going to need a small parser (parser generator even?) but I can map it from the selector syntax to code.

You should be able to do this type of merge in 5.2.0. 👍
