mongoose-bluebird-utils 
DEPRECATED
This module is deprecated, since it's a better and faster approach now to just promisify your models. This can be achieved with:
var Promise = require('bluebird');
var User = mongoose.model('User');
Promise.promisifyAll(User);
Promise.promisifyAll(User.prototype);
// Example:
var user = new User();
user.saveAsync()
// We need to use `spread` because `user.save` yields an array
.spread(function(user) {
});The promisifyAll bluebird function will add a Async posfixed promisified
method for all the methods in an object. This will be faster and more consistent
than using this module.
This is basically just a bunch of simple functions that serve as tiny sugars very often.
But, I find it kind of useful and don't want to flood a helper module into every project just to keep things tidy, so it's here.
Instalation
npm install mongoose-bluebird-utils
// [...]
var mpUtils = require('mongoose-bluebird-utils');
// [...]Examples
Before: Don't ever do this. This is terrible
var Promise = require('bluebird'),
mongoose = require('mongoose'),
User = mongoose.model('User');
function setNameToJohn (old_name) {
// note a mpromise promise is being returned, which may be harmful
return User.findOne({ name: old_name })
.then(function(user) {
if(!user){
var err = new Error('User not found');
err.status = 404; // I do this to bind HTTP response codes into errors
throw err;
}
user.name = 'John';
return Promise.promisify(user.save, user)();
});
}After:
var mongoose = require('mongoose'),
User = mongoose.model('User'),
mpUtils = require('mongoose-bluebird-utils');
function setNameToJohn (old_name) {
return mpUtils.findOneP(User, { name: old_name }, 'User not found')
.then(function(user) {
user.name = 'John';
return mpUtils.saveP(user);
});
}
