Concoction

A flexible preprocessing framework for Node.js

Concoction was designed to simplify preprocessing and transformation of objects within Node.js. Originally designed to be used with Iridium, it has been designed to be extremely flexible, easy to use and powerful. Along with the basic framework, a number of common application cases have been packaged, including the ability to rename an object's properties and convert an object's values from one form to another.

Features

• Simple To Use Concoction has been desinged from the start to make it as easy to use as possible. Simply instantiate a recipie, add some ingredients and apply it to an object - all operations are completely reversible.
• Reversible Operations Concoction was designed for systems which need two-way conversion support, the framework and all default operations have been designed to fully support reversible operations, and makes them as simple as possible - even applying the reversal operations in the correct order.
• Flexible Framework The framework has been designed to make implementing your own ingredients as simple as possible, only requiring that an ingredient provides apply and reverse methods.

Example

var Concoction = require('concoction');

var recipie = new Concoction([
	new Concoction.Rename({ _id: 'username', yearOfBirth: 'age' }),
	new Concoction.Convert({ 
		age: {
			apply: function(value) { return new Date().getYear() - value; },
			reverse: function(value) { return new Date().getYear() - value; }
		}
	})
]);

var person = {
	_id: 'spartan563',
	yearOfBirth: 1993
}

recipie.apply(person);
// person <- { username: 'spartan563', age: 20 }

recipie.reverse(person);
// person <- { _id: 'spartan563', yearOfBirth: 1993 }
