const { Kafka } = require('kafkajs');

// Kafka producer setup
const kafka = new Kafka({
  clientId: 'my-kafka-app',
  brokers: ['localhost:9092'] // Specify your Kafka broker(s) here
});

const producer = kafka.producer();

// Kafka consumer setup
const consumer = kafka.consumer({ groupId: 'my-group' });

// Connect to Kafka
async function connectToKafka() {
  await producer.connect();
  await consumer.connect();

  // Subscribe to Kafka topics
  await consumer.subscribe({ topic: 'my-topic', fromBeginning: true });
}

// Publish a message to Kafka
async function publishMessage(message) {
  await producer.send({
    topic: 'my-topic',
    messages: [{ value: message }]
  });
}

// Consume messages from Kafka
async function consumeMessages() {
  await consumer.run({
    eachMessage: async ({ topic, partition, message }) => {
      const value = message.value.toString();
      // Perform operations on received messages
      console.log(`Received message from topic ${topic}: ${value}`);
    }
  });
}

// Start Kafka integration
connectToKafka()
  .then(() => {
    console.log('Connected to Kafka');
    // Publish messages
    publishMessage('Hello Kafka!');
    // Consume messages
    consumeMessages();
  })
  .catch(error => console.error('Error connecting to Kafka:', error));
