While designing a feature to stream real-time updates via Server-Sent Events (SSE), I conceptualized a class that listens to multiple data sources, Redis channels, async functions, internal services, and re-emits those updates in a standardized event format to clients.
Out of curiosity, I used AI to check if there's an existing architectural pattern that aligns with this approach. To my surprise, I discovered the Event Aggregator pattern, introduced by Martin Fowler in Patterns of Enterprise Application Architecture. This pattern consolidates events from multiple sources and delivers them to interested listeners.
It’s fascinating how often we use patterns every day without knowing the vocabulary. Recognizing and naming them is what elevates our thinking:
“We all write code, but engineers understand the vocabulary of architecture, the shared language that helps us communicate and reason about complex systems.” - Mark Richards
Understanding this vocabulary is what differentiates a developer from a software engineer, it helps us design systems more effectively, communicate clearly, and reason about complexity with confidence.
