The resolve option has two parameters now and can return null. Thanks to Rene Haas (@​KingSora) madyankin/postcss-modules@86d8135

Parameters:

• file — a module we want to resolve
• importer — the file that imports the module we want to resolve

Return value: string | null | Promise<string | null>

postcss([
	require("postcss-modules")({
    	resolve: function (file, importer) {
			return path.resolve(
				path.dirname(importer),
				file.replace(/^@/, process.cwd()
			);
    	},
  	}),
]);
