There is something interesting in farcaster frames and the new solana blinks which makes crating microapps easy. I think we’re missing this in Nostr. Right now we have good tooling for full apps, and “medium” apps like listr.lol but not a microapp which is smaller. Think an app which exists within / for a single event kind. A good example is say a poll event kind where you could have a microapp which let people vote (publish a reply event), see results (aggregate and display all replies), propose a change to the poll options (edit/version the original event), etc…. There could me a kind of directory do poll microapp providers for each event kind / type of microapp. Or some nostr apps could hard code their own provider. If there is one directory it should be easy to run an alt so we don’t have a single point of centralization.
