Warn your users when their network goes down.
Make sure they don’t lose anything.
Fantastic, I had wanted to convert audio files to Data-URIs quite some time ago, but couldn’t quite find a way to do it…
But the ability to then store that content offline is really cool…
Another promise of cross-browser offline storage:
Need to test for mobile browsers, but worth storing this URL for now…
I was reading this article this morning:
And this statement caught my eye:
In Firefox’s IndexedDB implementation (and I believe IE’s too) the files are transparently stored outside of the actual database. This means that performance of storing a file in IndexedDB is just as good as storing the file in a filesystem. It does not bloat the database itself slowing down other operations, and reading from the file means that the implementation just reads from an OS file, so it’s just as fast as a filesystem.
Does this mean that storing physical files (images, mp3s, etc.) does not affect the size of the database?
If so, this could be huge for storing sites like the BMW Showcase for offline!
This looks pretty solid, but would of course require some testing…
