Sample text

If we want to declare our templates inline, we should use the template property instead. Luckily, in ES6, we are introduce with a way to create multiline strings easily. This feature is called template strings and it's declared with the back tick (`) character. ts] @Component({ selector: 'app-root', template: `

{{title}}

` }) Keeping the template inline is comfortable as we can see both the template and the component class in the same file. Embedding styles in component template We will probably want to use some CSS in our component's template.

Building a Basic Component At its core, an Angular 2 component is a class that is responsible for exposing data to the view and implementing user interaction logic. An Angular 2 component can be compared to the controller, scope, and view of Angular 1. How does Angular 2 know how to treat our class as a component? We need to attach metadata to the class to tell Angular how to treat it. The term metadata describes the additional information that we add to our code. This information is used by Angular 2 at runtime.
