How to use Dart http_server:VirtualDirectory

Question

I have been using the dart:route api for serving static files but I noticed that there is a core library called http_server that contains helper cl

The VirtualDirectory can work from inside the Future returned by HttpServer.bind. You can create a static file web server by using the following five lines of code:

HttpServer.bind('127.0.0.1', 8888).then((HttpServer server) {
    VirtualDirectory vd = new VirtualDirectory('../web/');
    vd.jailRoot = false;
    vd.serve(server);
});

You can make it more sophisticated by parsing the URI and pulling out service requests prior to serving out files.

import 'dart:io';
import 'package:http_server/http_server.dart';

main() {

  handleService(HttpRequest request) {
    print('New service request');
    request.response.write('[{"field":"value"}]');
    request.response.close();
  };

  HttpServer.bind('127.0.0.1', 8888).then((HttpServer server) {
    VirtualDirectory vd = new VirtualDirectory('../web/');
    vd.jailRoot = false;
    server.listen((request) { 
      print("request.uri.path: " + request.uri.path);
      if (request.uri.path == '/services') {
        handleService(request);
      } else {
        print('File request');
        vd.serveRequest(request);
      } 
    });
  });
}
