Making use of Meteor Streams as Message Threads about meteor-streams HOT 7 OPEN

How about this solution.

stream = new Meteor.Stream('private');

if(Meteor.isClient) {
  stream.on(Meteor.userId(), function(message) {
    alert('new message:', message);
  });

  sendMessage = function(message, to) {
    //to is an array of userIds (in your to field)
    stream.emit('send', message, to);
  }
}

if(Meteor.isServer) {
  stream.permissions.write(function(eventName) {
    return eventName == 'send';
  });

  stream.permissions.read(function(eventName) {
    return this.userId == eventName;
  });

  stream.on('send', function(message, to) {
    to.forEach(function(userId) {
      stream.emit(to, message);
    });
  });
}

Hi Arunoda,

Thanks for the reply. I will try this out..

Hi Arunoda,

Does the solution you provided has already a collection attached to it? or that is only reachable if the Receiving User is online?

from meteor-streams.

I simply use Meteor.userId() for the demonstration purpose. You can use a nickname, random string or anything depending on your app.

Hi Arunoda,

Sorry for the confusion. What i meant is that are the messages already STORED inside a collection so that whenever a user has logged in he/she can already see the message that is intended for them?

from meteor-streams.

Okay. Now I got it.

Meteor Streams does not handle the message persistence. You can use stream
filters http://arunoda.github.io/meteor-streams/filters.html to store
messages to the db.
So, in the very first you can get messages via a meteor method or using
streams itself.

Is this answer your question?
