I'm using SQL.js and it's great!
A few weeks ago, I built a program to help find jobs in New Zealand and Australia. It scrapes the Seek website, and allows me to make more complex queries (e.g. does not contain "right to live and work in this location")
Currently I'm running the scraper on a spare laptop manually every day or two. I'd rather set it up to work with Github Actions, but didn't get around to that yet.
