coffee-script-properties

Adds support for native javascript properties on coffeescript classes and objects.

Installation

npm install schemify

Usage

This module adds functionality to the global Function namespace, so you only need to require it once. A good place would be at the beginning of your application or module:

require "coffee-script-properties"

After this, you can start writing properties in your classes and objects.

Properties in classes

Getters

class Rectangle
    constructor: (@width = 10, @height = 10) ->
 
    @getter "area", () -> @width * @height
 
rectangle = new Rectangle
console.log rectangle.area  # 100 

Setters

 
class Person
    constructor: (@first, @last) ->
 
    @setter "name", (value) -> [@first, @last] = value.split " "
 
person = new Person
person.name = "John Doe"
console.log person.first    # John 
console.log person.last     # Doe 

Getters and setters together

class Product
    constructor: (@netPrice = 0, @taxes = 50) ->
 
    @property "price",
        get: -> @netPrice + @taxes
        set: (value) -> @netPrice = value - @taxes
 
product = new Product 100
console.log product.netPrice    # 100 
console.log product.price       # 150 
 
product.price = 500
console.log product.netPrice    # 450 
console.log product.price       # 500
