Re: [IndexedDB] How to recover data from IndexedDB if the origin domain don't exist anymore?

As a practical matter, you could just make an entry in your /etc/hosts mapping the domain to localhost and write a web page that dumps the indexeddb as json.  Serve that from your local web server and hit it with your browser.

It's pure client-side and server-less, being all the content of the webapp just static files and served with static web servers and CDNs, so all the user data is stored on IndexedDB on the user's computer and not any other place (there's no a "database server" that could be accesed in any form in any place at all).

Maybe defining in some way a "fake" origin for the IndexedDB object that all the webapps could have in common (in some way like a "magic word"), or the specification doesn't allow this possiblity at this moment? If so, how I could be able to do it?
