npm i @jm18457/kafkajs-msk-iam-authentication-mechanism 

Setup

const { Kafka } = require('kafkajs')
const {
  createMechanism
} = require('@jm18457/kafkajs-msk-iam-authentication-mechanism')

const kafka = new Kafka({
  brokers: ['kafka1:9092', 'kafka2:9092'],
  clientId: 'my-app',
  ssl: true,
  sasl: createMechanism({ region: 'eu-central-1' })
})

You can also use the old way of importing the library.

const { Kafka } = require('kafkajs')
const {
  Type,
  awsIamAuthenticator,
} = require('@jm18457/kafkajs-msk-iam-authentication-mechanism')


const provider = awsIamAuthenticator({
    region: 'eu-central-1'
})

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