What are the best practices for implementing the event bus pattern?

When implementing the event bus pattern, consider these best practices: 1. Keep events lightweight, 2. Use a centralized event bus, 3. Ensure event handlers are decoupled, and 4. Implement error handling.

Can you explain why decoupling event handlers is important?

Decoupling event handlers allows for greater flexibility and maintainability. It enables you to change or replace handlers without affecting other parts of the system.

What are some common pitfalls to avoid?

Common pitfalls include overloading the event bus with too many events, failing to manage event order, and not implementing proper error handling.

How can I test the event bus implementation?

You can test the event bus by simulating events and verifying that the correct handlers are triggered, and by checking for any errors during the process.
