# Dart Nostr Development Kit (NDK)

Build Status Coverage Pub License

NDK (Nostr Development Kit) is a Dart library that enhances the Nostr development experience.
NDK supplies you with high-level usecases like lists or metadata while still allowing you to use low-level queries enhanced with inbox/outbox (gossip) by default.
Our Target is to make it easy to build constrained Nostr clients, particularly for mobile devices.

# Apps using NDK

# Features / what does NDK do?

  • return nostr data based on filters (any kind).
  • automatically discover the best relays to satisfy the provided request (using gossip)
  • specify desired coverage on each request (e.g. x relays per pubkey)
  • publish nostr events to optimal relays or explicit relays
  • cache responses to save network bandwidth
  • stream directly from cache and network (if needed)
  • query and subscription, e.g., get data once; subscribe to data.
  • plugin cache interface, bring your own db or use included ones: inMemory
  • plug in verifier interface, bring your own event verifier, or use included ones: bip340, rust
  • plug in event signer interface, bring your own event signer, or use included ones: bip340, amber
  • contact list support, you can convert nostr_event to contact_list
  • nip51 list support, you can convert nostr_event to nip51_list

  • nip-47 Nostr wallet connect
  • nip-42 Authentication of clients to relays

# not Included

  • ready to use feeds, you have to build them on your own (🚫 not planned)
  • create && manage keypairs. You have to provide them (🚫 not planned)
  • threading, you can do this on your own if you move ndk or only the event_verifier into its own thread (🔜 planned)
  • support for request overrides (you have to close and reopen requests) (🤔 unsure)
