# ember-did-change-attrs [![Build Status](https://travis-ci.org/workmanw/ember-did-change-attrs.svg?branch=master)](https://travis-ci.org/workmanw/ember-did-change-attrs)

This addon is a WIP rethink of [ember-diff-attrs](https://github.com/workmanw/ember-diff-attrs) which offered a decorator style approach to this problem.

With `ember-did-change-attrs` we're going to solve the same problem using mixins instead of functions. The aim is to offer a simpler API which covers attribute change use cases that previously might have been solved using the [now deprecated `didReceiveAttrs` and `didUpdateAttrs` arguments](https://github.com/emberjs/rfcs/pull/191).

This API is still experimental, suggestions for improvements are encouraged and very much appreciated.

## Installation

`ember install ember-did-change-attrs`

## Usage

```js

import DidChangeAttrs from 'ember-did-change-attrs';

export default Ember.Component.extend(DidChangeAttrs, {

  didChangeAttrsConfig: {

    attrs: ['email']

  },

  didChangeAttrs(changes) {

    this._super(...arguments);

    if(changes.email) {

      let oldEmail = changes.email.previous,

          newEmail = changes.email.current;

      // Do stuff

    }

  }

});

```
