What I've added:

file_exists($sitePath.'/vite.config.ts')

// for some resources the base_url doesn't point to vite (http://localhost:3000), thus we handle it here
if (strpos($uri, '/node_modules/') === 0 && $this->isActualFile($resourcePath = $sitePath.$uri)) {
    return $resourcePath;
}

Place the file in ~/.config/valet/Drivers/. Valet will now also serve http://myapp/node_modules/some/file.
