如何在Meteor中存储特定于客户端的数据服务器端？

if (Meteor.isServer) {
  Meteor.startup(function () {
    Meteor.publish('myCollection', function () {
      return MyCollection.find();
    });
  });
}

if (Meteor.isClient) {
  Meteor.subscribe('myCollection');
}

if (Meteor.isClient) {
  MyCollection = new Mongo.Collection('myCollection');

  Template.myTemplate.onCreated(function () {
    this.subscribe('myCollection');
  });

  Template.myTemplate.helpers({
    items: function () {
      return MyCollection.find();
    }
  });
}

if (Meteor.isClient) {
  Meteor.startup(function () {
    MyCollection.insert({name: 'item1', value: 100});
    MyCollection.insert({name: 'item2', value: 200});
  });
}

<template name="myTemplate">
  <div>
    {{#each items}}
      {{name}} - {{value}}
    {{/each}}
  </div>
</template>
