I'm working on an IndexedDB-only wrapper for just this purpose. If you don't mind that it's not yet released, there's not readme and my commits are fast-paced and not descriptive than maybe you should [check it out][1].

There should be an example of every function in [indbapp.dev.js][2]. Here's how you would use the vanilla `InDBApp`:

	

I am in my third rewrite of a JavaScript application that heavily relies on IDB. I got sick of writing boilerplate IndexeDB code (setting up transactions, setting onsuccess callbacks, etc.) and decided to write a reusable interface.

That API is true to the IndexedDB spec and is now the core of InDB. It servers as a private object inside a wrapper that tries to simplify the interface. I'm writing my own [libraries][3] on top of it so I'm learning about what works and doesn't work and trying to improve InDB along the way.
