For building apps etc

Okay, maybe what you are looking for is: https://github.com/nostrband/nostr-login
NostrBook has protocol documentation if that's what you need: https://nostrbook.dev/protocol/
But if you just want to build something and have it work out of the box on Nostr, I'd try mkstack, it has all of this baked in already: https://soapbox.pub/tools/mkstack
Ahh exactly — many thanks. Thats exactly what im looking for
