Angular 2 - formControlName inside component

Question

I want to create a custom input component that I can use with the FormBuilder API. How do I add formControlName inside a component?

Template:

Answer 1

Angular 8 and 9: Use viewProvider in you custom component. Working example:

@Component({
    selector: 'app-input',
    templateUrl: './input.component.html',
    styleUrls: ['./input.component.scss'],
    viewProviders: [
        {
            provide: ControlContainer,
            useExisting: FormGroupDirective
        }
    ]
})

Now, when you assign formControlName, your component will attach itself to the parent form.
