Proof of concept nostr typescript event parser to extract metadata, and aid in rendering html or general data processing.
- Extract bech32-encoded entities (and convert to html a tags)
- Extract hashtags (and convert to html a tags)
- Extract mentions (and convert to html a tags)
- Extract relays (from r tags)
- Extract events (from e tags)
- Extract urls (fetch content-type, preview metadata, and convert to html a tags)
- Custom URL handlers
- Refactor into a library
- Query relays for mention pubkey kind0 metadata (possible caching)
- Event query/lookup (with optional author/pubkey lookup)
- Handle different event kinds
- Ideally more information on image urls like dimentions
npx ts-node index.ts
