What do you want to automate

with Kafka and Firebase Admin?

import { Kafka } from "kafkajs"
export default defineComponent({
  props: {
    kafka: {
      type: "app",
      app: "kafka",
    }
  },
  async run({steps, $}) {

    const kafka = new Kafka({
      brokers: [`${this.kafka.$auth.host}:${this.kafka.$auth.port}`],
    });

    const consumer = kafka.consumer({ groupId: 'TestGroup' });
    await consumer.connect()
    await consumer.subscribe({ topic: 'SampleTopic', fromBeginning: true });
    let consumedMessage = "";
    const eachMessage = async function({ topic, partition, message }){
      consumedMessage = message.value.toString();
      return consumedMessage;
    };  

    await consumer.run({
      eachMessage,
    });

    const producer = kafka.producer();  
    await producer.connect()
    await producer.send({
      topic: 'SampleTopic',
      messages: [
        { value: 'Welcome KafkaJS + Pipedream users! '+ new Date().toISOString() },
      ],
    });
    await producer.disconnect();

    const data = await consumer.describeGroup();
    return { consumedMessage, groupDescription: data };
  },
})

import admin from "firebase-admin"
export default defineComponent({
  props: {
    firebase_admin_sdk: {
      type: "app",
      app: "firebase_admin_sdk",
    },
  },
  async run({ steps, $ }) {
    // Enter values for the following parameters below this code step,
    // These get passed to the initializeApp method below.
    const { 
      projectId, 
      clientEmail, 
      privateKey,
      region = "firebaseio.com",
    } = this.firebase_admin_sdk.$auth

    // Before passing the privateKey to the initializeApp constructor,
    // we have to replace newline characters with literal newlines
    const formattedPrivateKey = privateKey.replace(/\\n/g, "\n")

    // See https://firebase.google.com/docs/reference/admin/node/admin.credential.html#cert
    if (!admin.apps.length) {
      admin.initializeApp({
        credential: admin.credential.cert({
          projectId,
          clientEmail,
          privateKey: formattedPrivateKey,
        }),
        databaseURL: `https://${projectId}-default-rtdb.${region}/`,
      })
    }
  },
})
