const { Kafka } = require('kafkajs')

const registry = new SchemaRegistry({ host: 'http://registry:8081/' })
const consumer = kafka.consumer({ groupId: 'test-group' })

const run = async () => {
  await consumer.connect()
  await consumer.subscribe({ topic: 'test-topic', fromBeginning: true })

  await consumer.run({
    eachMessage: async ({ topic, partition, message }) => {
      const decodedKey = await registry.decode(message.key)
      const decodedValue = await registry.decode(message.value)
      console.log({ decodedKey, decodedValue })
