seneca-globals-store

Seneca node.js data-storage plugin for Globals DB.

This module is a plugin for the Seneca framework. It provides a storage engine that uses MongoDB to persist data.

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.

Support

Current Version: 1.1.0

Tested on: Node 0.10.33, Seneca 0.6.1

Quick example

var seneca = require('seneca')()
seneca.use('globals-store',{
  path:'/globals/db/root/dir'
})
 
seneca.ready(function(){
  var apple = seneca.make$('fruit')
  apple.name  = 'Pink Lady'
  apple.price = 0.99
  apple.save$(function(err,apple){
    console.log( "apple.id = "+apple.id  )
  })
})

Install

npm install seneca
npm install seneca-globals-store

Install GlobalsDB by following this Quickstart Guide.

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

Native Driver

As with all seneca stores, you can access the native driver, in this case, the globals.Cache db object using entity.native$(function(err,db){...}). For more information read the Official Globals DB Node.js API guide.
