the title seems like click bait. Its very misleading to the point of being intentional. The title to me implies that there are intention to replace the use of sqlite with this javascript database.

sqlite (from their website) "SQLite is a self-contained, high-reliability, embedded, full-featured, public-domain, SQL database engine. SQLite is the most used database engine in the world."

When I click on a link I see a nodejs application with a bunch of info on how to use it. No justification or details on implementation, or how real problems were solved.

How portable is RxDB (PouchDB)? Can you run it on a embeded device without a browser? How full featured is it? Is it crash safe?

For instance see how sqlite is tested https://www.sqlite.org/testing.html

Finally how is this any better than simply using the databases built into the browsers, like html5 storage?
