Hi friendly Nostr devs.
What's the best pattern for push?
I have a server with a db of npubs and push tokens from my app.
If an npub follows another user, and that user goes live, I would push to the npub's token "user is live! heres a link"
Should my server maintain a persistent connection to multiple relays subscribed to all kind 30311s to identify when all lives start?
And, similarly for follow lists, should I persistently subcribe to all kind 3s? (And then wash them against npubs in my db, or perhaps specify 1000 author pubkeys in a req?)
Or some other pattern? It's all seeming quite inefficient and spammy on public relays...
Maybe I am missing an obvious layup e.g. somehow populate my own local relay with all kinds 3 and 30311's and connect locally with impunity?
What pattern have others used? Are there docs on this? #asknostr @npub1gcxz...nj5z @Sebastix 🙏🙏
