How do I migrate file-loader with postTransformPublicPath to asset?

We currently apply the following file-loader configuration:

{
	test: imageFileExtensions,
	loader: "file-loader",
	options: {
		name: "[path][name].[ext]",
		outputPath: url => getRelativeImagePath(url),
		publicPath: url => getRelativeImagePath(url),
		postTransformPublicPath: p => `__webpack_public_path__ + ${p}`
	}
}

According to the docs, migrating this loader with the asset module should look something like this:

{
	test: imageFileExtensions,
	type: "asset/resource",
	generator: {
		filename: "[path][name][ext]",
		outputPath: url => getRelativeImagePath(url),
		publicPath: url => getRelativeImagePath(url)
		// postTransformPublicPath???
	}
}

However, as the commented line indicates, there is no support for the postTransformPublicPath option in the asset module…

How would I proceed from here, any suggestions?

there is no postTransformPublicPath alternative. webpack does __webpack_public_path__ + ${p} by default

[vankop]

e.g. you have webpack.config.js

module.exports = {
  output: { publicPath: "/public" },
  module: {
     rules: [
       {
         type: "asset",
         generator: {
             publicPath: "/public-asset"
         }
       }
     ]
  }
};

webpack will generate /public-asset for assets, if you need to respect output.publicPath you should pass generator.publicPath="/public/public-asset"

btw if you need to respect output.publicPath, you can just omit generator publicPath and outputPath options
