Network Connection needs

This integration needs network access to the server where the service is running.

See the Network access page for details about how to achieve that.

Credential configuration​

To configure this credential you need a Client ID, one or more Brokers hosts and username and password if needed for auth.

Optionally you can set any of the extra config params you can see here.

Here you have an example of a filled credential configuration form in YepCode:

Integration​

New integration from credential
const kafka = yepcode.integration.kafkajs('credential-slug')
New integration from plain authentication data
const { Kafka } = require('kafkajs')

const kafka = new Kafka({
  clientId: 'my-app',
  brokers: ['kafka1:9092', 'kafka2:9092'],
  ssl: true,
  sasl: {
    mechanism: 'plain',
    username: 'my-username',
    password: 'my-password'
  }
})

Producer​

Producer
const producer = kafka.producer()

await producer.connect()
await producer.send({
  topic: 'test-topic',
  messages: [
    { value: 'Hello KafkaJS user!' },
  ],
})

await producer.disconnect()

Consumer​

Consumer
const consumer = kafka.consumer({ groupId: 'test-group' })

await consumer.connect()
await consumer.subscribe({ topic: 'test-topic', fromBeginning: true })

await consumer.run({
  eachMessage: async ({ topic, partition, message }) => {
    console.log({
      value: message.value.toString(),
    })
  },
})
