A Backbone.Sync replacement using leveldb

#LevelSync LevelSync is a Backbone.Model replacement which uses LevelDB via the levelup interface.

Installation

npm install --save levelsync

Usage

var levelup = require('level');
var db = levelup('./path/to/db');
var Backbone = require('backbone');
Backbone.sync = require('levelsync')(db);

var StatBlock = Backbone.Model.extend({
  defaults: {
    'str': 8,
    'con': 8,
    'wis': 8,
    'dex': 8,
    'int': 8,
    'chr': 8
  }
});

var myCharacter = new StatBlock();
myCharacter.set('str', 18);
myCharacter.set('name', 'LEROY JENKINS');
myCharacter.save(myCharacter.toJSON(), {cb: function(err){
  if(!err) console.log(myCharacter.get('name'), 'was saved');
}});

// or
var promise = myCharacter.save();
promise.when(function(){
  console.log(myCharacter.get('name'), 'was saved');
});

Changes from Backbone

The options hash accepts a new parameter, cb. This callback will be use for all the level operations if set. It's signature should be (err, data). If this is not set, a q promise will be returned instead.
