sockets - Meteor：从外部源（套接字）发布数据

Question

我将 getstream.io API 与他们的库一起使用。他们的 JS 库中有以下钩子：

newsFeed.subscribe(function callback(data) {
        //do something with the data   
 });

我创建了一个包来包装 NPM 库。我现在想使用此功能并将结果发布到仅限客户端的集合。

我要试试这个，但我不知道它是否可以：

Meteor.publish("newsFeed", function () {
  var self = this;
  var newsFeed = GetstreamClient.feed('notification', 'newsFeed');
  //TODO : Use MeteorAsync ?
  newsFeed.subscribe(function callback(data) {
        self.added("clientNewsCollection", Random.id(), {event: data});
    });
  self.ready();
});

这个可以吗 ？还是我应该这样做？

// This will be used to store the subscription objects for later management
var subs = { };

// The helper publication
Meteor.publish('newsFeed', function() {

       var subscription = this;
       subs[subscription._session.id] = subscription;

       subscription.onStop(function() {
          delete subs[subscription._session.id];
       });
});

var newsFeed = GetstreamClient.feed('notification', 'newsFeed');
//TODO : Use MeteorAsync ?
 newsFeed.subscribe(function callback(data) {
        for (var subscriptionID in subs) {
             var subscription = subs[subscriptionID];
             subscription.added("clientNewsCollection", Random.id(), {event: data});
        }
  });
