force 0.2.6

A real time web framework for dart, embracing websockets

Dart Force Framework

A realtime web framework for dart.

With this framework communication between client and server becomes easy, without any boilerplate code.

Walkthrough

Client side

First create a client. ForceClient forceClient = new ForceClient(); forceClient.connect();

Listen on the connection, when it is established and when is been broken.

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

Listen on messages with the request of text.

 forceClient.on("text", (e, sender) {
      ...
 });

You can also send messages to the server.

forceClient.send('text', request);

Server Side

Instantiate a forceserver.

ForceServer fs = new ForceServer( port: 9223 );

Listen on messages of type text and react upon that.

fs.on('text', (e, sendable) { 
    var json = e.json;
    var line = json['line'];
    sendable.send('text', { 'line': line });
});

You can also serve files from the server part.

fs.start().then((_) {
    fs.serve("/client.dart").listen((request) { 
      fs.serveFile("../web/client.dart", request);
    });
});

TODO

• fallback support for legacy browser with no capability of websockets
• adding authentication support and security support
• writing tests
