# Queue Events Listeners

To register a `QueueEvents` instance, you need to use `QueueEventsListener` decorator:

```typescript
import {
  QueueEventsListener,
  QueueEventsHost,
  OnQueueEvent,
} from '@taskforcesh/nestjs-bullmq-pro';

@QueueEventsListener('queueName')
export class TestQueueEvents extends QueueEventsHost {
  @OnQueueEvent('completed')
  onCompleted({
    jobId,
  }: {
    jobId: string;
    returnvalue: string;
    prev?: string;
  }) {
    // do some stuff
  }
}
```

And then register it as a provider:

```typescript
@Module({
  imports: [
    BullModule.registerQueue({
      name: 'queueName',
      connection: {
        host: '0.0.0.0',
        port: 6380,
      },
    }),
  ],
  providers: [TestQueueEvents],
})
export class AppModule {}
```
