Attr Accessor

Convenience factories for creating getter/setters.

Installation

Attr Accessor is available via npm:

npm install attr-accessor

Or for usage in the browser:

dist/attr-accessor.js
dist/attr-accessor.min.js

Usage

Pass in an object to attr.reader or attr.writer to obtain a getter or setter factory respectively:

get = attr.reader(object)
set = attr.writer(object)

ES2015 introduced classes and has support for getter/setters.

CoffeeScript, on the other hand, has had no elegant way of defining getter/setters, until now. Use its destructuring syntax in combination with attr.accessor to obtain both factories:

[get, set] = attr.accessor(object)

Use attr.accessors when dealing with classes to obtain two prototypal / instance-bound factories as well as two static factories:

[get, set, @get, @set] = attr.accessors(object)

Example

class Person
  [get, set, @get, @set] = attr.accessors(this)

  group = []

  constructor: (@firstName, @lastName) ->
    group.push this

  get name: ->
    "#{@firstName} #{@lastName}"

  @get count: ->
    group.length

new Person('John', 'Doe').name # John Doe
Person.count # 1

Development & Contribution

Attr Accessor is written in ES2015, compiled by Babel, developed with Gulp and tested through Mocha.

Getting this toolchain up and running, is easy and straight-forward:

Get the code:

git clone git://github.com/timkurvers/attr-accessor.git

Download and install Node.js – including npm – for your platform.
Install dependencies:
```
npm install
```
Run npm run gulp which will automatically build and test the project when source files change.
