ember-frost-component

This project aims to make a better Ember base component to extend.

Installation

ember install ember-frost-component

Usage

Better Components

Below is an example of a component that extends the component from this addon:

import FrostComponent, {PropTypes} from 'ember-frost-component'

export default FrostComponent.extend({
  propTypes: {
    foo: PropTypes.string,
    bar: PropTypes.number.isRequired,
    baz: PropTypes.oneOf([
      PropTypes.bool,
      PropTypes.string
    ])
  },

  getDefaultProps () {
    return {
      foo: 'This is going to be highly profitable'
    }
  }
})

Property Validation

The idea of propTypes comes from the world of React and is implemented to have an almost identical API in the Ember world. Below is a list of possible propTypes to validate against.

• array
• bool
• EmberObject
• func
• number
• object
• oneOf
• string

Default Property Values

In Ember you can set default property values on a component class itself but sometimes this bites you when you end up with a property containing an array of selected items or a state object, where all instances of the component end up sharing that same array or object. Uncovering this issue is not always an easy task and so getDefaultProps was also implemented (thanks to the React team for this concept as well).
