I have written an SDK that encapsulates a bunch of logic and functionality.
Typically, I would use event listeners/callbacks to provide feedback to the application using the SDK, but that is not idiomatic in Go.
It is my understanding that channels and goroutines fill the void of callbacks but what is a way to implement this?
Say for example, my SDK has a number of events that I want to notify the main application about. Would I use one channel based on an Event
struct. This Event
would contain a _type
field which specifies the event type, then a data
field of type interface{}
similar to Object
in Java. The receiver would then check the type and cast the data accordingly.
Either the above approach or one channel for event then the app listens for whatever channels it is concerned with.
For the record I prefer the former approach but unsure about it's implementation.
Has anybody achieve this before and how did you implement?
