socket.io-dart

Port of awesome JavaScript Node.js library - Socket.io v2.0.1 - in Dart

Usage

import 'package:socket_io/socket_io.dart';

main() {
    var io = new Server();
    var nsp = io.of('/some');
    nsp.on('connection', (Socket client) {
      print('connection /some');
      client.on('msg', (data) {
        print('data from /some => $data');
        client.emit('fromServer', "ok 2");
      });
    });
      io.on('connection', (Socket client) {
        print('connection default namespace');
        client.on('msg', (data) {
          print('data from default => $data');
          client.emit('fromServer', "ok");
        });
      });
      io.listen(3000);
}

// JS client
var socket = io('http://localhost:3000');
socket.on('connect', function(){console.log('connect')});
socket.on('event', function(data){console.log(data)});
socket.on('disconnect', function(){console.log('disconnect')});
socket.on('fromServer', function(e){console.log(e)});

// Dart client
import 'package:socket_io_client/socket_io_client.dart' as IO;

IO.Socket socket = IO.io('http://localhost:3000');
socket.on('connect', (_) {
  print('connect');
  socket.emit('msg', 'test');
});
socket.on('event', (data) => print(data));
socket.on('disconnect', (_) => print('disconnect'));
socket.on('fromServer', (_) => print(_));

Multiplexing support

Same as Socket.IO, this project allows you to create several Namespaces, which will act as separate communication channels but will share the same underlying connection.

Room support

Within each Namespace, you can define arbitrary channels, called Rooms, that sockets can join and leave. You can then broadcast to any given room, reaching every socket that has joined it.

Transports support

Refers to engine.io

• polling: XHR / JSONP polling transport.
• websocket: WebSocket transport.

Adapters support

• Default socket.io in-memory adapter class. Refers to socket.io-adapter
