mongoose-bird v0.0.1

mongoose-bird

blue bird support for mongoose.

based on mongoose-2.

What is it?

mongoose-bird uses the bluebird's Promise.promisifyAll function which will add a Async function for each function on mongoose :

• mongoose.Model
• mongoose.Model.prototype
• mongoose.Query.prototype

So all mongoose-bird does it to call:

 Promise.promisifyAll(mongoose.Model);
 Promise.promisifyAll(mongoose.Model.prototype);
 Promise.promisifyAll(mongoose.Query.prototype);

usage

var mongoose = require('mongoose-bird')(require('mongoose'));
// verbose way: mongooseQ is unused
var mongoose = require('mongoose'),
    mongooseBird = require('mongoose-bird')(mongoose)
// shortest way: mongoose will be loaded by mongoose-bird
var mongoose = require('mongoose-bird')();

• use Async model statistics functions:

SomeModel.findByIdAsync(....blahblah...)
  .then(function (result) { ... })
  .catch(function (err) { ... });

• use Async model functions:

var someModel = new SomeModel(...);
someModel.populateAsync()
  .then(function (result) { ... })
  .catch(function (err) { ... });

• use Async query methods:

SomeModel.find(...).where(...).skip(...).limit(...).sort(...).populate(...)
  .execAsync() // no 'Async' suffix for model statics except for execAsync()
  .then(function (result) { ... })
  .catch(function (err) { ... });

• to use Async with spread:

var mongoose = require('mongoose-bird')(require('mongoose'));
SomeModel.updateAsync(...)
  .spread(function (affectedRows, raw) { ... })
  .catch(function (err) { ... });
...
var model = new SomeModel();
...
model.saveAsync()
  .spread(function (savedDoc, affectedRows) { ... })
  .catch(function (err) { ... });
...

• to define custom statics/instance methods using Async

SomeSchema.statics.findByName = function (name) {
  return this.findAsync({name: name}); // NOTE: returns Promise object.
};
...
var SomeModel = mongoose.model('Some', SomeSchema);
SomeModel.findByName('foo').then(function(result) {
  console.log(result);
});

NOTE: this is not a feature of mongoose-bird

That's all folks!
