# es-decorate
> ES7 decorators for CoffeeScript
## Why
Libraries such as
[Angular](https://angular.io/docs/js/latest/api/annotations/)
and
[Aurelia](http://eisenbergeffect.bluespire.com/aurelia-update-with-decorators-ie9-and-more/)
are starting to use decorators according to the API proposed in
https://github.com/wycats/javascript-decorators
which is supported in Babel 5+ and TypeScript 1.5
On the other hand, it seems CoffeeScript
won't be adding decorators any time soon:
- https://github.com/jashkenas/coffeescript/issues/76
- https://github.com/jashkenas/coffeescript/issues/996
`es-decorate` fills the syntactic gap providing a
helper function that can apply decorators compliant
with the proposed decorator API.
## Install
npm install --save es-decorate
## Usage
Following the examples in https://github.com/wycats/javascript-decorators:
``` coffeescript
decorate = require 'es-decorate'
# Class decorator must be assigned to variable or property.
Foo = decorate F('color'), G, class # Class name is optional in CoffeeScript
# Method with redundant name
bar: decorate 'bar', @, F('color'), G, ->
# Or just...
decorate 'baz', @, F('color'), G, ->
# ...if no code analyzer will miss the explicit method declaration
```
Multiline declaration:
``` coffeescript
Foo = decorate [
F 'color'
G
H
I 123
J
], class Foo
```
Less dumb example, using Angular 2:
``` coffeescript
decorate = require 'es-decorate'
{Component, View} = require 'angular2/angular2'
AppComponent = decorate [
Component selector: 'my-app'
View template: '
My first Angular 2 App
'
], class AppComponent
constructor: ->
```
