🚀 Enhancing Dynamic Component: The Advanced Input Binding for NgComponentOutlet
in Angular
NgComponentOutlet
is a directive in Angular that provides a declarative approach to dynamic component loading. Traditionally, developers using Angular had to manually manage component factories and view containers to achieve dynamic component loading, but NgComponentOutlet
this simplifies the process. In this article, we'll explore the new input binding feature for NgComponentOutlet
and how it enhances the dynamic loading of components.
Simplifying with NgComponentOutlet
@Component({
selector: 'app-root',
standalone: true,
imports: [NgComponentOutlet],
template: `
<ng-container *ngComponentOutlet="userComponent" />
`,
})
export class AppComponent implements OnInit {
userComponent = UserComponent;
}
Where userComponent
is the component type that needs to be loaded dynamically.
The New Input Binding Feature
The recent update to NgComponentOutlet
introduces a new input binding that allows for more control over the dynamically loaded component.
Previously, to pass inputs or receive outputs from a dynamically loaded component, developers needed to manage it manually. With the new input binding, this process becomes more straightforward.
Passing Inputs:
You can now bind component inputs directly:
AppComponent
@Component({
selector: 'app-root',
standalone: true,
imports: [NgComponentOutlet],
template: `
<ng-container *ngComponentOutlet="userComponent; inputs: userInfo" />
`,
})
export class AppComponent implements OnInit {
userComponent = UserComponent;
userInfo = {
name: 'John',
surname: `Davidson`,
};
}
UserComponent
@Component({
selector: 'app-user',
standalone: true,
template: `Full name: {{ name }} {{ surname }}`,
})
export class UserComponent{
@Input() name: string;
@Input() surname: string;
}
In the above code, userInfo
data pass from AppComponent to UserComponent
Conclusion
The new input binding feature for NgComponentOutlet
further simplifies dynamic component loading in Angular. By providing a more declarative way to pass inputs and handle outputs, Angular continues to enhance its capabilities, making developers' lives easier. If you haven't started using NgComponentOutlet
for dynamic component loading yet, now might be a great time to explore its benefits!
