Handle the quota exceeded error globally

[lewispham]

Basically, I want to show a warning message to users when the storage quota for my app is exceeded. Catching the error QuotaExceededError on every write operations (caches.open, cache.put, etc) is quite painful. How can I handle it globally? Or is there any better approach for this situation?

What's painful about it? Give that there may be other reasons for storage methods to fail, would we be saving much by having a global event for this?

I'm not sure about others. But my app was designed to use Cache API as a replacement for browser cache. So I use it pretty much everywhere in my app. Catching errors of every single write operations is quite painful to me. I actually expect a global event fired when the storage quota is exceeded, so that I can show some recommendations to users.
