To test the rss in a podcast app:
https://podcasts.puhcho.me/npub1u4x0m5grq47ahu42tmdtjq9pak7gsgz68uw2lagu44stn6rt2v7qnzgmhv(this will run temporary).
In general self-host
https://github.com/SnowCait/nostr-rss and it can use nostter client or you can change the code to nostrudel, nostr band, coracle etc to pull rss of notes.
If the notes have a link in content, that will be played in the podcast apps if enclosure url is added like this:
```
console.log(event);
const urlPattern = /(https?:\/\/[^\s]+)/;
const urlMatch = event.content.match(urlPattern);
const enclosureUrl = urlMatch ? urlMatch[0] : null;
feed.item({
title: enclosureUrl,
description: event.content,
date: new Date(event.created_at * 1000),
url: `
https://nostter.app/${nip19.neventEncode({ id: event.id })}`,
enclosure: {
url: enclosureUrl,
type: 'audio/mpeg'
},
guid: `
https://nostter.app/${nip19.neventEncode({ id: event.id })}`
});
```
