It's not that simple. 1. The spec died, because it didn't get two independent implementations. Everyone merely wrapped sqlite, which meant sites could rely on being bug-compatible with all the sqlite weirdnesses (e.g. column type "floating point" parses as integer column type), and making any future upgrades or fixes of sqlite a Web-wide version of pain of upgrading IE6 used for an intranet site. 2. IndexedDB API is a pain to use, because it's designed to be used directly. In the spirit of extensible web manifesto, it's a low-level primitive for JS libraries to build convenient higher-level abstractions on top of. It's like an "assembly" of storage. It's supposed to enable building higher-level databases on top, so you can have SQL or NoSQL with whatever dialect you want, without burdening the platform with it. Use Dexie, localForage, ydn or such.
