Publishing results of a REST API call in Meteor.

publications.js

// I need to integrate my company's meteor app with a 3rd party legacy application. Both apps will operate independently, but need to perform CRUD on the legacy datasource. Is there a way to use a REST api built on the legacy system as a datasource in the meteor app?

//Basically I'm looking to do something like the below pseudocode:

Meteor.publish("items", function() {
  HTTP.get('https://legacy.app.url/api/items',{ },function(err, items){
      return items;
      //Or return items.toMeteorCollection()
  })
});

// Here's a way to do this.

// Define a local collection on the server (not backed by Mongo) and update the results from the callback to HTTP.get. Something like:

Items = new Meteor.Collection({connection: null});

HTTP.get("http://foo.com", function (err, items) {
  _.each(items, function (item) {
    Items.insert(item);
  });
});

Meteor.publish("items", function () {
  return Items.find();
});

Unfortunately, this doesn't work. I wish it did though!
