seneca-simpledb-store

Seneca node.js data-storage plugin for SimpleDB.

This module is a plugin for the Seneca framework. It provides a storage engine that uses Simple DB to persist data. This module is for production use. It also provides an example of a document-oriented storage plugin code-base.

The Seneca framework provides an ActiveRecord-style data storage API. Each supported database has a plugin, such as this one, that provides the underlying Seneca plugin actions required for data persistence.

Current Version: 0.1.0

Quick example

Install

npm install seneca
npm install seneca-simpledb-store

Usage

You don't use this module directly. It provides an underlying data storage engine for the Seneca entity API:

var entity = seneca.make$('typename')
entity.someproperty = "something"
entity.anotherproperty = 100

entity.save$( function(err,entity){ ... } )
entity.load$( {id: ...}, function(err,entity){ ... } )
entity.list$( {property: ...}, function(err,entity){ ... } )
entity.remove$( {id: ...}, function(err,entity){ ... } )

Queries

The standard Seneca query format is supported:

• entity.list$({field1:value1, field2:value2, ...}) implies pseudo-query field1==value1 AND field2==value2, ...
• you can only do AND queries. That's all folks. Ya'll can go home now. The Fat Lady has sung.
• entity.list$({f1:v1,...},{sort$:{field1:1}}) means sort by field1, ascending
• entity.list$({f1:v1,...},{sort$:{field1:-1}}) means sort by field1, descending
• entity.list$({f1:v1,...},{limit$:10}) means only return 10 results
• entity.list$({f1:v1,...},{skip$:5}) means skip the first 5
• entity.list$({f1:v1,...},{fields$:['field1','field2']}) means only return the listed fields (avoids pulling lots of data out of the database)
• you can use sort$, limit$, skip$ and fields$ together
• entity.list$({f1:v1,...},{native$:[{-mongo-query-},{-mongo-options-}]}) allows you to specify a native mongo query, as per node-mongodb-native

Native Driver

As with all seneca stores, you can access the native driver, in this case, the node-seimpledb-native object using entity.native$(function(err,collection){...}).

Test

In order to execute the tests you will need to supply your AWS credentials in the file keys.mine.js:

cd test;
cp keys.js keys.mine.js
vim keys.min.js
mocha mongo.test.js --seneca.log.print
