Dynoga
Disclaimer
Dynoga is a lightweight library to use DynamoDB with JavaScript objects.
We use CRUD naming for easy matching with Backbone.ioBind

db = new Dynoga

accessKeyId: config.dynamoDB.accessKeyId
secretAccessKey: config.dynamoDB.secretAccessKey
region: config.dynamoDB.region
Create an item
db.create "mytable", item, (err, model) ->
if err then console.log err
console.log model

keys: Key/value object, a hash is mandatory
db.read "mytable", keys, (err, model) ->
