force_sendable.dart Line 19

log.info("breadcasting ... to $key");

should be

 log.info("broadcasting... to $key");

Just for a start I would like to see the Dart source for a simple "Hello" example server that responds with "Hello Foo" when it receives a "Foo" message. I could not figure that out from the instructions on the Pub page. Thanks.

Having to build in development is not very practical. Is it possible to serve the files in the /web directory directly? If not, it should be a feature.

1. Dart Force "Hello World" for Google App Engine.
2. Integration With Google Cloud Storage though Cargo.
3. Helpers for easy deployment.

I want to use timer to send data to the client for every 3 seconds after websocket connection has been establish .
I don't know to how to do this use dart-force !! Is there any example for reference ???

Let us look at the how a clientside DB api should look like.

It would be nice to provide a reply method, so you can just call

sender.reply('received', data);

instead of

sender.sendTo(fme.wsId, 'received', data);

Add @receivable and @receiver annotations in forceclient so we can use these annotations on that side!

Hi,

I actually use dart-force for my project, and i'm in a situation where getting the possibility of connecting 2 server together would be nice.

I don't know if it's in the "philosophy" of this library or not. but for me it will be nice.

Hi, I was just wondering if it was possible to send file/data other than strings through the use of forceServer.send(). If possible, would you be able to typecast the object once it reached the client? I figured once it is serialized you would have to do a conversion afterwards.

If the browser doesn't support WebSocket then use long polling as a last resort and setup automatically.

Hi,

I saw this in an example:

forceClient.on("notifications"

Using strings can get us into trouble (hard to check with tools, too easy to misspell, no code completion)

Instead, can we do this:

forceClient.onNotifications.listen((e) => ...

Thanks!

Mentioned as a long term goal but has no issue associated with it. Appears that the client is allowed to set profile setting and no current hook to valid it nor what topics can be subscribed to and by whom.

Hi,

Actually, dart-force use it's own http server implementation for ForceServer.

Is it planned to allow a user to provide its own implementation (like a parameter in the creation of ForceServer) ?

start long polling server ... /ws/polling Uncaught Error: SocketException: OS Error: An invalid argument was supplied.
I believe its the case that in your simple_web_server.dart line13 you need to choose InternetAddress.ANY_IP_V4 for windows systems.

Saw that your tictactoe example uses a server.register method but there is no documentation of how to properly use it.

Hello, I personallly don't like using mustache as view rendering engine, however I would like to know if this framework supports jasmine. does it?

There is the ability to serve files but would be desirable to have a way to set a publicly accessible folder(s). A default to ../web probably makes the most sense.

A raw value has been left in the code:

part of dart_force_server_lib;

class ServerSocketConnector extends Connector {

int port;
String address;

StreamController _controller;

ServerSocketConnector({this.address: '127.0.0.1', this.port: 4041}) {
_controller = new StreamController();
}

Future start() {
ServerSocket.bind(this.address, 4041) // Just here
.then((serverSocket) {
serverSocket.listen((socket) {
_controller.add(new ServerSocketWrapper(socket));

       });
});
return _completer.future;

}

}

Currently there is no routing support for a ForceServer. There are times even when using websockets that you can't avoid REST urls (for example when working with external APIs like paypal) for use as redirects. Are there any plans to support routing in Force?

When the connection is lost with the server, we are going to store all the socket events into websql or localstorage.
Whenever the connection is back established the events will be fired in the same order. So you can bring the state of the client back in order with the server.

We will use Cargo for this.

So we will have a keep alive connection with our clients!

Support for non-websocket enabled browsers is mentioned as a long term goal but has no issue associated with it.

I have this minimal code and I keep getting

INFO: default: "GET /_ah/health?IsLastSuccessful=no HTTP/1.1" 503 -
WARNING: All instances may not have restarted

when I try to start the local server. Here is the code

server.dart

library force_angular;

import 'package:force/force_serverside.dart';
import 'package:forcemvc/force_mvc.dart';
import 'package:mustache4dart/mustache4dart.dart';
import 'package:appengine/appengine.dart';

main() {

    // Create a force server
    ForceServer fs = new ForceServer();

    runAppEngine(forceServer.requestHandler).then((_) {

        // Setup logger
        fs.setupConsoleLog();

        // we need to change {{ into [[ because of angular
        if (fs.server.viewRender is MustacheRender) {
            MustacheRender mustacheRender = fs.server.viewRender;
            mustacheRender.delimiter = new Delimiter('[[', ']]');
        }

        // Tell Force what the start page is!
        fs.server.use("/", (req, model) => "angularforce");

    });
}

I had actually started my own Dart websocket based client/server thing (codenamed javelin). Its does some acks and registration steps to allow things like automatic configurable RC4 encryption.

It that something you might want to include in force if I gave you the code?

We need to add a new event that will listen to changes in the profile data coming from the client

How about, instead of:

 forceClient.onConnecting.listen((e) {
      if (e.type=="connected") {
        ...
      } else if (e.type=="disconnected") {
        ...
      }
 });

The forceClient can return a Future that completes when the connection is complete. I'd like to try to avoid checking types against strings if possible. Hard to spellcheck and refactor and statically analyze.

Check the WebSocket class for some inspiration on how to deal with a connection that completes and disconnects.
