• Kafka installed on your system
• Frontend application running on localhost:8080

1. Open Command Prompt or Terminal.
2. Navigate to the Kafka directory.
3. Run the following command to create a Kafka topic named chatz:

   bin\windows\kafka-topics.bat --create --topic chatz --partitions 3 --replication-factor 1 --bootstrap-server localhost:9092 

   This command will create a topic named chatz with 3 partitions and a replication factor of 1.

If the frontend generates the wrong client ID, follow these steps:

1. Open a web browser.
2. Enter the following URL in the address bar: http://localhost:8080/fetchPendingMessages?clientId=2

Replace 2 with the correct client ID of the disconnected websocket.

• If you encounter any issues during setup, refer to the Kafka documentation or the frontend application's documentation for troubleshooting steps.
• Ensure that all dependencies are installed and configured correctly before running the application.

• Make sure Kafka is running and accessible on localhost:9092.
• Verify that the frontend application is configured to connect to the correct Kafka server and topic.
