@kenny, I don’t have a lot of experience with SSE, but I think so. See https://github.com/pedestal/pedestal/issues/359. Pedestal cleans up everything it creates when shutting down an SSE stream and it provides a hook via the on-client-disconnect option which can be set when starting the event stream.

https://github.com/pedestal/pedestal/blob/5b2450f67b3ea5ad8e853467e6305cee5125497c/service/src/io/pedestal/http/sse.clj#L211

the doc-string states that on-client-disconnect takes an arg but the code indicates it’s a no args fn.

actually

I’m wrong

The on-client-disconnect function does take one argument, the context.
