# ember-computed-style [![Build Status](https://travis-ci.org/ivanvanderbyl/ember-computed-style.svg?branch=master)](https://travis-ci.org/ivanvanderbyl/ember-computed-style) [![Ember Observer Score](https://emberobserver.com/badges/ember-computed-style.svg)](https://emberobserver.com/addons/ember-computed-style)

![Ember Computed Style](https://raw.githubusercontent.com/ivanvanderbyl/ember-computed-style/master/data/emberComputedStyleLogo.png)

Provides a simple computed property mixin for Ember Components to compute styles 
from objects similar how it can be done in React.

# Usage

Take this example code:

```javascript
import computedStyle from 'ember-computed-style';

export default Ember.Component.extend({
  style: computedStyle('styleProperties'),

styleProperties: {
    position: 'absolute',
    top: 10,
    left: 50
  },

attributeBindings: ['style'],

});
```

This will set style to a CSS style string computed from the returned object from
the handler function. The value of this will be correctly encoded as:

```css
  position: absolute; top: 10px; left: 50px;
```

Properties which are not designated to have a unit value will be left as is, 
otherwise `px` unit will be added if they're a Number.

You can also compute it from multiple property bindings, if each of them return
an object keyed on the CSS property name:

```javascript
import computedStyle from 'ember-computed-style';

export default Ember.Component.extend({
  style: computedStyle('horizontalPosition', 'verticalPosition', 'positionType'),

positionType: {
    position: 'absolute'
  },
  
  verticalPosition: computed('targetRect', function() {
    const targetRect = this.get('targetRect');

return {top: targetRect.top + 10};
  }),

horizontalPosition: computed(function() {
    return {left: 50};
  }),

attributeBindings: ['style'],
});
```
