How do I configure an HTTP server to serve a client with package dependencies?

I have a project with a server and a client (each in its own directory and setting up separate packages), so:

$ ls -l project/server
pubspec.yaml
server.dart
packages

$ ls -l project/client
pubspec.yaml
packages
web

$ ls -l project/client/web
index.html
main.css
client.dart

      

        
        
        
      

    

Now I am unable to get the HttpServer to serve anything outside of the web directory with the following code:

void directoryHandler(dir, request) {
  var indexUri = new Uri.file(dir.path).resolve('index.html');
  virDir.serveFile(new File(indexUri.toFilePath()), request);
}

void main() {
  Logger.root.onRecord.listen(new SyncFileLoggingHandler("server.log"));

  virDir = new VirtualDirectory(Platform.script.resolve('../client/web').toFilePath())
    ..allowDirectoryListing = true
    ..followLinks = true
    ..directoryHandler = directoryHandler;

  HttpServer.bind(InternetAddress.ANY_IP_V4, 8080).then((HttpServer server) {
    log.info("HttpServer listening on port:${server.port}...");
    server.listen((HttpRequest request) {
      if (WebSocketTransformer.isUpgradeRequest(request)) {
        log.info("Upgraded ${request.method} request for: ${request.uri.path}");
        WebSocketTransformer.upgrade(request).then(handleWebSocket);
      } else {
        log.info("Regular ${request.method} request for: ${request.uri.path}");
        virDir.serveRequest(request);
      }
    });
  });
}

      

        
        
        
      

    

And in index.html:

  <script src="../packages/browser/dart.js"></script>

      

        
        
        
      

    

It seems that if I resolve VirtualDirectory directly to the client / web, then normal static files work, but then nothing outside (namely the package directory) is pulled in. And if I try to serve only the client the directory and specify web / index.html in the handler then nothing else gets. I also tried copying the package directory to the net, but they don't seem to make it either.

Note, I've seen other examples where HttpServer points to the build directory, but I'm trying to test my project before I compile the dart to js.

Overall, I am just confused about how to set up a server / client project where the server actually serves the client and the client has its own packages. I cannot find any literature on the internet for this particular case.
