Building a Event System in Go Without Union Types
One challenge in Go development is the absence of union types, which can make it tricky to design clean interfaces for event processing systems. When working with various event types with different payloads, we often resort to type assertions or empty interfaces, resulting in verbose and potentially error-prone code. In this post, I’ll demonstrate a pattern that creates a convenient, structured event interface without relying on union types. The Problem When designing event-driven systems, we typically need to: ...
