socket_io
JS/Node 庫 Socket.io 的移植版本。可實現跨平台的即時、雙向及基於事件的通訊。
socket.io-dart:socket.io 的 Dartlang 版本 https://github.com/socketio/socket.io
^3.0.0^1.0.1^3.0.4^1.0.0^1.16.8^1.11.0以下為英文專案原文快照,最新內容請造訪 GitHub。
Port of awesome JavaScript Node.js library - Socket.io v2.0.1 - in Dart
import 'package:socket_io/socket_io.dart';
main() {
var io = new Server();
var nsp = io.of('/some');
nsp.on('connection', (client) {
print('connection /some');
client.on('msg', (data) {
print('data from /some => $data');
client.emit('fromServer', "ok 2");
});
});
io.on('connection', (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(_));
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.
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.
