Out of curiosity how did you choose between onBeforeUnmount and unmounted?

When I looked up lifecycle events for guidance, I followed this reference: Destruction Hooks – Cleaning Things Up which said:

Because this is before the component starts to get torn down, this is the time to do most, if not all, of the clean up. At this stage, your component is still fully functional and nothing has been destroyed yet.

It did seem more useful to have some of the component still around just incase I needed it, versus at unmount:

at this point, most of your component and its properties are gone so there’s not much you can do.

eventStream.close();
});

getInitialDeploymentState();
