You use Phoenix PubSub to broadcast them each time you create, update or delete them.

Then in the handle_info on your live view you can use send_update/2 to update the client.

You are looking for Change Data Capture which goes well beyond the scope of PostgreSQL. If you can achieve CDC with your DB then you should be able to pretty easily propagate events to any other frontend/backend system, LiveView included.

Hi thanks for the reply because I never heard of CDC before(probably because when it comes to backend development I’m just a novice). I do think though that CDC goes way beyond the scope of what I’m looking for. I’m just trying to learn LiveView and everything I’ve found about is so far in terms of examples is user-initiated actions changing state rather than server events. I think if I followed this CDC path I would get bogged-down in the details of CDC rather than develop the frontend.
