Access IndexedDB from Web Workers

Question

I can not seem to figure out HOW to use indexedDB inside web worker. I've tried a lot of different ways, but indexedDB is always "undefined" in worker scope. I thought it was supposed to be accessible via indexedDB or self.indexedDB???

self.indexedDB = self.indexedDB || self.msIndexedDB || self.mozIndexedDB || self.webkitIndexedDB || self.OIndexedDB;

indexedDB = indexedDB || msIndexedDB || mozIndexedDB || webkitIndexedDB || OIndexedDB;

all are undefined ... i even iterated through the properties of the self object, and there was no indexedDB property or method. fwiw, i'm using ff 18, AND, ff nightly (21a), and i tried it with chrome.

Answer 1

Update September 2015: Accessing IndexedDB from web worker in Firefox is now possible: https://bugzilla.mozilla.org/show_bug.cgi?id=701634

If you want to use IndexedDB in chrome just use the following line:

indexedDB = typeof window == 'object' ? window.indexedDB : webkitIndexedDB;

Answer 2

indexeddb is accessible from Web Workers since firefox 37 (released March 31st, 2015).

IndexedDB
Database to store records holding simple values and hierarchical objects.
