Implements async bindings to Observable.
|
|
|
|
# Example
|
|
|
|
In this example we bind the description observable to the DOM. The async pipe will convert an observable to the
|
|
latest value it emitted. It will also request a change detection check when a new value is emitted.
|
|
|
|
```
|
|
@Component({
|
|
selector: "task-cmp",
|
|
changeDetection: ON_PUSH
|
|
})
|
|
@View({
|
|
inline: "Task Description {{description|async}}"
|
|
})
|
|
class Task {
|
|
description:Observable<string>;
|
|
}
|
|
|
|
```
