<strong>Angular is still unpackaged and in alpha</strong>. This quickstart does not

reflect the final build process for Angular. The following setup is for those who
|

want to try out Angular while it is in alpha.
|

|

p.
|
||||
For the sake of this quickstart we recommend using the
|
||||
<a href="https://github.com/davideast/conscious"> <code>es6-shim</code> GitHub repository</a>.
|
||||
This repository will provide a faster start. <code>es6-shim</code> includes Angular and dependencies to compile ES6 in incompatible browsers.
|
||||
|
||||
p Clone the repository inside of aleady existing project.
|
||||
In a new directory, create a <code>pubspec.yaml</code> file.
|
||||
Add angular2 and browser as dependencies,
|
||||
and add the angular2 transformer:
|
||||
[PENDING: if the transformer isn't working in time,
|
||||
remove it and use reflection in Dartium instead.

Angular builds on top of ES6, the new specification of the JavaScript language.
|

Not all ES6 features are available in all browsers. The following es6-shim
|

repository allows you to use ES6 in the browser today.

p.

Angular is available on npm. Configuring Angular to run ES6 in the browser

|

|
||||
p.
|
||||
Create a file named <code>app.es6</code> at the root of the project.
|
||||
The <code>.es6</code> extension signifies that the file uses ES6 syntax.
|
||||
Using the ES6 module syntax you can import the required modules from Angular2.
|
||||
Under the same directory, create a <code>web</code> directory.
|
||||
Create a file under <code>web</code> named <code>main.dart</code>.
|
||||
Edit <code>web/main.dart</code> to import the angular2 library:
|
||||
|
||||
pre.prettyprint.linenums
|
||||
code import {Component, Template, bootstrap} from 'angular2/angular2';
|
||||
|
||||
p The above import statement will import the three modules from Angular. These modules load at runtime.

Components are custom HTML elements. Angular uses components to empower HTML.
|
||||
Components structure and repre.prettyprint.linenumssent the UI. This quickstart
|
||||
demonstrates the process of creating a component. This component will have the tag of app.
|
||||
A component is a custom HTML element.
|
||||
In this step, you create a component that has the tag <b><app></b>.
|
||||
The Dart code for a component consists of a class
|
||||
with annotations that describe the component.
|
||||
|
||||

|

Update <code>web/main.dart</code> to contain the following code,
|
||||
which defines the app component:
|
||||
|
||||

|
||||
code.
|

A component annotation provides meta-data about the <code>component</code>.
|
||||
An annotation can always identified by its at-sign — <code>@</code>.
|
||||
p.
|

The <code>@Component</code> annotation defines the HTML tag for the component.
|

The selector property specifies the tag. The <code>selector</code> property is a CSS selector.

The <code>@Template</code> annotation defines the template to apply to the
|
||||
component. This component uses an inline template, but external templates are
|
||||
available as well. To use an external template specify a <code>url</code> property
|

p.

The component controller is the backing of the component's template. A component

controller uses ES6 <code>class</code> syntax.
|

A template has access to all the public properties and methods
|
||||
of its component controller.
|

[PENDING: Do we really want to use the term "component controller"?

Angular provides a <code>bootstrap</code> function that renders a
