```ts
import { NgHcaptchaModule } from 'ng-hcaptcha';

@NgModule({
    imports: [
        // Option #1
        // Set the sitekey globally for every hCaptcha component
        NgHcaptchaModule.forRoot({
            siteKey: 'YOUR_SITEKEY',
            languageCode: 'de' // optional, will default to browser language
        }),

        // Option #2
        // This option requires you to set the [siteKey] property for every hCaptcha component
        NgHcaptchaModule.forRoot()
    ]
})
```

## Usage

Template:
```html
<!-- 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:
```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:
```ts
@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');
      }
    );
  }

}
```
