Use kafkaJS admin client trough NestJS microservices module

Question

as the title suggest. Is there a possibility to use the admin client functions from KafkaJS trough the nestJS module? I'am trying to have a more detailed grip on the creation of topics trough the API.

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. — Community, Feb 26 '22 at 18:28

Create admin client and access to the topic list in onModuleInit :

async onModuleInit() {
    const kafka = new Kafka({
      clientId: 'my-app',
      brokers: ['localhost:9092'],
    });
    this.admin = kafka.admin();

    // get list of topics
    const topics = await this.admin.listTopics();

   // or create new topic
    await this.admin.createTopics({
        topics: [{
            topic: 'sample-topic',
            numPartitions: 1,
            replicationFactor: 1,
        }],
    });
 }

You can create a service for admin client and inject it in every module you want.
