A reaction is just another kind of event, with it's content being an emoji.
As per NIP-25, it's not restricted to kind1 notes & can be used to react to any event kind.
(You can even react to reactions, probably if you use a CLI client 😅)
Woah
I just got a notification in nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 that someone “reacted” ie 🤙 to a DM!!?
Is it that the ability to Shaka a note is just not shown within Damus DMs, but technically part of the protocol? #asknostr
Learned something new today!
