API for responding to errors

[insin]

I occasionally see this sort of thing being console.warn()-ed when using the Hacker News API, which results in my app displaying a loading indicator until the content in question is deleted or becomes available.

"FIREBASE WARNING: on() or once() for /v0/item/8477507 failed: Error: permission_denied: Client doesn't have permission to access the desired data. "

I can see that it's the Firebase library itself doing it, but it doesn't seem to have an API for error handling - I'd expect to be able to do an on('error', callback) or similar.

I can't pick out a way to catch errors from the minified Firebase code. Is there API for this, or are there any plans to add error handling?

OK, I'm an idiot, it's part of the .on() API:

on(eventType, callback, [cancelCallback], [context])

(Protip: investigate fully, THEN create issue)

Reactfire doesn't allow you to provide a callback for the cancelCallback argument. Can this be supported?

Thanks for the suggestion @insin - discussion related to this issue is happening in the PR you created (#24).

This was merged in but I forgot to close this issue. I will do a ReactFire release next week and at that point, this change will be live. Thanks!
