Hey #[1] , sure, if you want a nice demo application to see how to use it, you can check out https://rbr.bio/npub107jk7htfv243u0x5ynn43scq9wrxtaasmrwwa8lfu2ydwag6cx2quqncxg (it's open source https://github.com/adamritter/light-nostr-client ). Also feel free to add me on telegram (@AdamRitter)
https://github.com/adamritter/nostr-relaypool-ts Nostr relaypool TS is a RelayPool implementation on top of nostr-tools' SimpleRelayPool. Implements subscription batching and deduplication and also has optional caching. Probably worth exploring using it in your nostr apps if you are implementing all of this yourself, i want to give it a spin for Habla although I'm not sure if it implements nip-33.
