possibilities

From Meteor's documentation:

In Meteor, your server code runs in a single thread per request, not in the asynchronous callback style typical of Node. We find the linear execution model a better fit for the typical server code in a Meteor application.

This guide serves as a mini-tour of tools, trix and patterns that can be used to run async code in Meteor.

Basic async

Sometimes we need to run async code in Meteor.methods. For this we create a Future to block until the async code has finished. This pattern can be seen all over Meteor's own codebase:

    public $uri_templates = array();

    public function __construct($name, $uri_templates) {
        $this->name = $name;

var empty, get, set,
  __hasProp = {}.hasOwnProperty;

get = Ember.get;
set = Ember.set;

empty = function(obj) {
  var key;
  for (key in obj) {
    if (!__hasProp.call(obj, key)) continue;

Ember Router Async Facelift

The Ember router is getting number of enhancements that will greatly enhance its power, reliability, predictability, and ability to handle asynchronous loading logic (so many abilities), particularly when used in conjunction with promises, though the API is friendly enough that a deep understanding of promises is not required for the simpler use cases.

// Implement debounce until backburner implements a proper debounce

  var self = Ember.run.backburner,
      args = arguments,
      wait = pop.call(args),

/**
 * `Ember.MergedArray` is an array that observes multiple other arrays (called source arrays) for changes and includes
 * all items from all source arrays in an efficient way.
 * 
 * Usage:
 * 
 * ```javascript
 * var obj = Ember.Object.create({
 *   people: [
