Is it possible to import Directive into Component? I want to avoid importing into ngModule.declarations.
I am following CustomDirective for Telerik Angular Grid. It is suggested to populate grid with customDirective, but I will need this directive in only one component, so I want to avoid importing in ngModule, to avoid name collisions.
Edited:
I tried with viewProviders but it does not work. Here is plunkr that works (directive imported in ngModule):
@NgModule({
imports: [ BrowserModule ],
declarations: [
AppComponent,
HighlightDirective
],
bootstrap: [ AppComponent ]
})
export class AppModule { }
and here is plunkr which doesn't work. (directive imported in Component):
@NgModule({
imports: [ BrowserModule ],
declarations: [
AppComponent,
],
bootstrap: [ AppComponent ]
})
export class AppModule { }
@Component({
moduleId: module.id,
selector: 'my-app',
templateUrl: 'app.component.html',
viewProviders: [HighlightDirective]
})
export class AppComponent {
color: string;
}

Yes, this is entirely possible, you can use Component decorator's viewProviders option, like this:
@Component({
template: '<div myCustomDirective>Hello</div>',
selector: 'app-hello',
viewProviders: [MyCustomDirective]
})
export class Component {}
But I should warn this is not really a best practice, trty to stick with the modules.
