decorator

Decorate your objects easily.

Great for keeping common view presentation logic in one place.

Example

Given you have some data that needs some presentation logic

var data = {
	firstName: 'Daffy',
	lastName: 'Duck',
	addressLine1: 'Level 10',
	addressLine2: '28 Wells St',
	city: 'Sydney',
	postcode: 2000
	country: 'Australia'
}

Create a decorator

// file: UserDecorator.js

var assign = require('object-assign');
var d = require('decorator');

// methods you would like accessible on the decorated object
module.exports = assign(d, {
	
	fullName: function() {
		return this.firstName + ' ' + this.lastName;
	},
	
	formattedAddress: function() {
		return this.addressLine1 + join("\r\n")
			+ this.addressLine2 + join("\r\n")
			+ this.city + join(" ") + this.postCode + join("\r\n")
			+ this.country;
	}	
});

Decorate

// file: someOtherFile.js

var UserDecorator = require('../path/to/UserDecorator.js');

// data from a service like a `Store` or `API` 
var user = UserDecorator.decorate(data)
user.fullName()                // Daffy Duck
user.formattedAddress()        // You get the idea...

// Old properties still accessible as normal
user.firstName					 // Daffy
