h4 Component Annotations
.c6
p
| The annotation section is where you can describe meta-data about your
code component
| You can always identify an annotation by its
code @
| sign. The <code>Component</code> annotation tells Angular what the HTML tag will be for your component. The tag is specified by using the <code>selector</code> property. The <code>selector</code> property is just a CSS selector.
p
| The <code>Template</code> annotations tells Angular what template to apply to your 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 and give it the path to the template.
pre
code
| @Component({
| selector: 'app'
| })
| @Template({
| inline: `
| &lt;h1&gt;Hello {{ name }}&lt;/h1&gt;

h4 Component Controller
.c6
p
| The component controller is defined using the ES6 <code>class</code> syntax. This <code>class</code> is the backing of the component's template.
pre
code
| class AppComponent {
| constructor() {
| this.name = "Alice";
| }
| }
p
| Templates read directly from their component controllers. Any properties or functions placed on the component controller can be directly accessed from the template.
p
| In the template above binds to a <code>name</code> property through the <code>{{ }}</code> syntax. In the component's constructor the name property is being set to Alice. When the template is rendered, Alice will appear instead of <code>{{ name }}</code>.
