Triggering Changes with Actions You can think of a component as a black box of UI functionality. So far, you've learned how parent components can pass attributes in to a child component, and how that component can use those attributes from both JavaScript and its template. But what about the opposite direction? How does data flow back out of the component to the parent? In Ember, components use actions to communicate events and changes. Let's look at a simple example of how a component can us

Installing Ember Getting started with Ember is easy. Ember projects are created and managed through our command line build tool Ember CLI. This tool provides: Modern application asset management (including concatenation, minification, and versioning). Generators to help create components, routes, and more. A conventional project layout, making existing Ember applications easy to approach. Support for ES2015/ES6 JavaScript via the Babel project. This includes support for JavaScript modules, wh

DS.Store Class Extends: Ember.Service Defined in: addon/-private/system/store.js:140 Module: ember-data The store contains all of the data for records loaded from the server. It is also responsible for creating instances of DS.Model that wrap the individual data for a record, so that they can be bound to in your Handlebars templates. Define your application's store like this: app/services/store.js import DS from 'ember-data'; export default DS.Store.extend({ }); Most Ember.js application

Customizing a Component's Element By default, each component is backed by a <div> element. If you were to look at a rendered component in your developer tools, you would see a DOM representation that looked something like: <div id="ember180" class="ember-view"> <h1>My Component</h1> </div> You can customize what type of element Ember generates for your component, including its attributes and class names, by creating a subclass of Ember.Component in your JavaSc

Object Inspector The Inspector includes a panel that allows you to view and interact with your Ember objects. To open it, click on any Ember object. You can then view the object's properties. Viewing Objects Here's what you see when you click on an object: The Inspector displays the parent objects and mixins that are composed into the chosen object, including the inherited properties. Each property value in this view is bound to your application, so if the value of a property updates in your

findRecord (store, type, id, snapshot) Promise Defined in addon/adapter.js:88 The findRecord() method is invoked when the store is asked for a record that has not previously been loaded. In response to findRecord() being called, you should query your persistence layer for a record with the given ID. The findRecord method should return a promise that will resolve to a JavaScript object that will be normalized by the serializer. Here is an example findRecord implementation: app/adapters/appli
