autobind decorator

This is a class or method decorator which will bind methods it to an object so this always points to an object instance within a method.

As decorators are a part of future ES7 standard they can only be used with transpilers such as Babel.

Installation:

% npm install autobind-decorator core-js

Example:

import 'core-js/modules/es6.reflect' // Will use Reflect polyfill if exposed
import autobind from 'autobind-decorator'

class Component {

  constructor(value) {
    this.value = value
  }

  @autobind
  method() {
    return this.value
  }
}

let component = new Component(42)
let method = component.method // .bind(component) isn't needed!
method() // returns 42


// Also usable on the class to bind all methods

@autobind
class Component { }
