When should I use the event bus pattern?

What is the event bus pattern and when should I use it?

The event bus pattern is a design pattern that facilitates communication between different components in a system without them needing to know about each other. You should use it when you have multiple components that need to communicate asynchronously.

Can you give me an example of when to use it?

Sure! If you have a user interface that needs to update based on changes in the backend, using an event bus allows the UI to listen for events without tightly coupling it to the backend logic.

What are the benefits of using the event bus pattern?

The main benefits include decoupling components, improving scalability, and making it easier to manage complex interactions in your application.

Are there any downsides to using this pattern?

Yes, potential downsides include increased complexity and difficulty in debugging, as the flow of events can become hard to trace.
