References: Signal Forms

Best Practices

Use signal-based FormControl

import { signal } from '@angular/forms';

@Component({})
export class MyComponent {
  name = signal('');
  
  updateName(value: string) {
    this.name.set(value);
  }
}

Use withValidators

email = signal('', {
  validators: [Validators.required, Validators.email]
});

Use withAsyncValidators

username = signal('', {
  asyncValidators: [uniqueUsernameValidator]
});
