Synopsis

• Isomorphic Resource engine for JavaScript
• Resources are business logic wrapped in prototypical models with schema and validation
• Resources support several data-providers
  • Memory
  • File-System
  • CouchDB
  • MongoDB
  • REST
  • socket.io

Status

Features

• Data Validation
• Simplified Data Model Management
• Relationships
• Data Provider Extensible
• Simplified Cache Control

Installation

$ [sudo] npm install resourceful

Usage

Simple case

var resourceful = require('resourceful');
 
var Creature = resourceful.define('creature', function () {
  //
  // Specify a storage engine
  //
  this.use('couchdb');
 
  //
  // Specify some properties with validation
  //
  this.string('diet');
  this.bool('vertebrate');
  this.array('belly');
 
  //
  // Specify timestamp properties
  //
  this.timestamps();
});
 
//
// Now that the `Creature` prototype is defined
// we can add custom logic to be available on all instances
//
Creature.prototype.feed = function (food) {
  this.belly.push(food);
};

API

Resource Constructor Methods

These methods are available on all user-defined resource constructors, as well as on the default resourceful.Resource constructor.

• Resource.get(id, [callback]): Fetch a resource by id.
• Resource.update(id, properties, [callback]): Update a resource with properties.
• Resource.destroy(id, [callback]): Destroy a resource by id.
• Resource.all([callback]): Fetches all resources of this type.
• Resource.find(properties, [callback]): Find all resources of this type which satisfy properties conditions.
• Resource.save(inst, [callback]): Saves the specified resource instance inst by overwriting all properties.
• Resource.create(properties, [callback]): Creates a new instance of the Resource with the specified properties.
• Resource.new(properties): Instantiates a new instance of the Resource with the properties.

Resource Instance Methods

• Resource.prototype.save([callback])
• Resource.prototype.update(properties, [callback])
• Resource.prototype.destroy([callback])
• Resource.prototype.reload([callback])

Relationship Constructor Methods

These methods are available on all user-defined resource constructors which are in a relationship

• Parent.children(id, [callback]): Fetches all the children for the specified id.
• Parent.createChild(id, properties, [callback]): Create a child for id with the specified properties.
• Child.byParent(id, [callback]): Fetches all the children for the parent given by id.

Relationship Instance Methods

• Parent.prototype.children([callback])
• Parent.prototype.createChild(properties, [callback])
• Child.prototype.parent([callback]): Fetches the parent of the given child instance.

Relational Resources

Resourceful supports a simple Resource.parent API, supports one-one, one-many, and many-many relationships.
