Usage

Template:

<!-- Regular usage -->
<ng-hcaptcha (verify)="onVerify($event)"
              (expired)="onExpired($event)"
              (error)="onError($event)">
</ng-hcaptcha>

<!-- Usage in forms -->
<!-- The value of the form control will be the verification token -->
<form [formGroup]="formGroup" (submit)="onSubmit()">
    <ng-hcaptcha formControlName="captcha"></ng-hcaptcha>
</form>

<!-- Invisible captcha -->
<button ngHcaptchaInvisibleButton
        (verify)="onVerify($event)"
        (expired)="onExpired($event)"
        (error)="onError($event)">Click me</button>

TS:

onVerify(token: string) {
    // The verification process was successful.
    // You can verify the token on your server now.
}

onExpired(response: any) {
    // The verification expired.
}

onError(error: any) {
    // An error occured during the verification process.
}

Execute hCaptcha programmatically

The hCaptcha verification process can also be executed programmatically:

@Component({
  selector: 'hc-programmatically',
  templateUrl: './programmatically.component.html',
  styleUrls: ['./programmatically.component.scss']
})
export class ProgrammaticallyComponent {

  constructor(private hcaptchaService: NgHcaptchaService) { }

  verify() {
    this.hcaptchaService.verify().subscribe(
      (result) => {
        console.log('SUCCESS', result);
      },
      (err) => {
        console.log('FAILED', err);
      },
      () => {
        console.log('COMPLETE');
      }
    );
  }

}
