Step 1: Setup Kafka (I used the following blog): https://blog.soshace.com/the-ultimate-introduction-to-kafka-with-javascript/
Step 2: Onc you have both the kafka-server and the kafka-zookeeper running, you can start the producer using ts-node src/producer.ts
Step 3: In a new terminal window, run ts-node src/consumer.ts to start the client.
Step 4: Go back to the producer, and start typing your data.
