javascript - Meteor: Reactive joins exposes intermediate data -

i'm using publish-composite perform reactive join (i'm sure specific package not matter). , seeing intermediate data gets pushed client.

in following example:

meteor.publishcomposite('messages', function(userid) {     return {     find: function() {       return meteor.users.find(         { 'profile.connections.$': userid }       );     },     children: [{       find: function(user) {         return messages.find({author: user._id});       }     }]   } }); 

all users has userid in profile.connections exposed client. know can create mongodb projection sensitive stuff not exposed. wondering if can prevent first find() query cursor getting client @ all.

are trying publish messages particular user if user connection logged on user? if so, maybe work:

meteor.publishcomposite('messages', function(userid) {   return {     find: function() {       return meteor.users.find(this.userid);     },     children: [{       find: function(user) {         return meteor.users.find(           { 'profile.connections.$': userid }         );       },       children: [{         find: function(connection, user) {           return messages.find({author: connection._id});         }       }]     }]   }; }); 

that equivalent :

meteor.publish('message',function(userid) {   var user = meteor.users.find({_id : this.userid, 'profile.connections.$' : userid});    if (!!user) {     return messages.find({author: userid});   }    this.ready(); });
