Make XHR from Dart Server


Make XHR from Dart Server

around this issue You could either use the HttpClient class from dart:io - there is a very basic example in that link.
OR you could use the http pub package which might be a little bit easier to use. Example from their pub page:
code :
import 'package:http/http.dart' as http;

var url = "http://example.com/whatsit/create";
http.post(url, body: {"name": "doodle", "color": "blue"})
    .then((response) {
  print("Response status: ${response.statusCode}");
  print("Response body: ${response.body}");
});

What is the best way to make multiple requests to the same server in Dart?

Does that help First, use the http Pub package.
For making multiple requests to the same server, keep a persistent connection open by using http.Client. This is better than making multiple single requests. Here is some code that shows how this can be done:
code :
import 'package:http/http.dart' as http;


void main() {
   var url = 'http://httpbin.org';
   var client = new http.Client();
   client.get('${url}/foo')
       .then((response) {
         print(response.body);
         return client.get('${url}/bar');
        })
       .then((response) {
         print(response.body);
       });
       .whenComplete(client.close);
}

I wish this help you You need a server to serve static content because there are a lot of features with those libraries that are pulling your resources in dynamically. This isn't a Dart or Polymer issue, this is a browser security feature. By default, you can't make AJAX calls to your local machine. Pub serve is handling this for you, but you can chose any server you want to serve your local assets.
Contrary to some of what the other answers are saying, you don't need to build your Dart code when you're in Dartium. Dartium has the Dart VM built in for that very reason.

To fix the issue you can do There is no way to interact with JavaScript like this on the server. A workaround would be a service in a language where you have proper MSSQL support and your Dart server app communicates with this service using a network connection to pass queries and results.

it should still fix some issue This issue was resolved with package upgrade. The problem was with conflicting package versions. If anyone happens to stumble upon this issue again I would highly suggest checking the package versions and performing a pub upgrade.

I wish this help you Günter beat me to it by a couple minutes, but I've already typed it out so here's a slight alternative which would also work and avoids using 'then' completely.
code :
Future<List<Item>> getAllItems() async {
  var client = new Client();
  List<String> itemsIds = ['1', '2', '3']; //different ids

  List<Response> list = await Future.wait(itemsIds.map((itemId) => client.get('sampleapi/$itemId/next')));

  return list.map((response){
    // do processing here and return items
    return new Item();
  }).toList();
}
