|
import { useRequestBuilder, useUserProfile } from "@snort/system-react";
|
|
import { FlatNoteStore, NostrSystem, RequestBuilder, TaggedNostrEvent } from "@snort/system";
|
|
|
|
// singleton nostr system class
|
|
const System = new NostrSystem({});
|
|
|
|
// some bootstrap relays
|
|
["wss://relay.snort.social", "wss://nos.lol"].forEach(r => System.ConnectToRelay(r, { read: true, write: false }));
|
|
|
|
export function Note({ ev }: { ev: TaggedNostrEvent }) {
|
|
// get profile from cache or request a profile from relays
|
|
const profile = useUserProfile(System, ev.pubkey);
|
|
|
|
return (
|
|
<div>
|
|
Post by: {profile.name ?? profile.display_name}
|
|
<p>{ev.content}</p>

const rb = new RequestBuilder("get-posts");
|
|
rb.withFilter().authors([props.pubkey]).kinds([1]).limit(10);
|
|
|
|
return rb;
