Kafka-node exposes an Admin API that has a describeGroups() method.

For example:

const client = new kafka.KafkaClient();
const admin = new kafka.Admin(client);
admin.describeGroups(['my-consumer-group'], (err, res) => {
    console.log(JSON.stringify(res, null, 1));
});

You can also use Kafka-node Admin API to list groups .
