How to loop while waiting for an Websocket event?

[ekianjo]

Hi there,
Thanks for the websocket package. It seems to do exactly what I need to interact with a specific service using websockets, but I am faced with one issue and I am not really sure how to deal with it:

• Thru the websocket I trigger an event that takes about 20 seconds to complete. But it can also become longer in certain cases.
• there is an onMessage event that I want to use to monitor that signals when the task is completed.

If I use a while loop in R with a sys.sleep() value, it does not seem to work: it seems to hijack the R process and the events from the websocket do not register at all, until I forcibly stop the loop. I also tried with future to create such a loop, but again it does not seem to work either.

Any idea on how to do this in R?

Does the later::run_now(1L) method in #52 work?
