Hello @kevinding0218, thanks for interest in this project! I hopye you will learn from it.

About your questions:

1. The topic param in the comments is not supposed to be there. I have removed it from the code. It was a leftover from an earlier version and I forgot to removed it after I refactored the code.
2. I use a fanout Exchange to do pub-sub. The idea is that every event might be interesting for every consumer. Using fanout, every consumer can define a queue and bind it to the Exchange. This way the sender is unaware of its' consumers, which reduces coupling. Whether this is the right way to distribute your events, totally depends on the situation. For Pitstop there are not many consumers and we control everything in the solution. In a more enterprise-like environment with multiple teams and more consumers, it might be better to distribute your messaging load differently (either using multiple Exchanges, or routing-keys (which I support in the Messaging library) or ...). So I use it like this, but don't assume this is the only way to do messaging.

I hope this makes sense and I've answered your questions.
