Simple relations for Backbone models. Not as full-featured as Backbone-relational (http://backbonerelational.org/) or Supermodel (http://pathable.github.io/supermodel/), but pretty lightweight and concise. Disclaimer: I excerpted this from some other code I wrote and haven't tested it independently. Use at your own risk
View model.js
var relationEvents = ['add', 'change', 'remove', 'reset', 'sort', 'destroy', 'request', 'sync'];
var Model = exports.Model = Backbone.Model.extend({
hasMany: {
// Subclasses can override to set relations like this:
//
// key: function () { return new Collection([], options); },
},

Augment Mongoose with Q promises. In some cases the method is an alternative to an existing promise-returning methods, like `qexec` vs. Mongoose's native `exec`. In other cases it's providing an operation that Mongoose doesn't give promises for, such as `qsave` and `qcreate`.
View gist:5873309
var mongoose = require('mongoose');
// Workaround for the fact that chai-as-promised isn't working with Mongoose promises:
// https://github.com/domenic/chai-as-promised/issues/30
mongoose.Query.prototype.qexec = function () {
return Q.npost(this, 'exec', arguments);
}
mongoose.Model.qcreate = function () {
return Q.npost(this, 'create', arguments);

Start of a simple promise-based HTTP client, based on Q-IO and inspired by SuperAgent
View client.js
var http = require('q-io/http');
var BufferStream = require('q-io/buffer-stream');
// Response
function Response(promise) {
this.promise = promise;
this.status = this.promise.get('status');
You can’t perform that action at this time.
