nostr-spring-boot-starter

Spring boot starter projects for building Nostr applications. Whether you're building your own client or custom relay software, this framework provides most of what you need to write scalable and efficient solutions effortlessly.

Note: Most code is still experimental - this is work in progress.

Planned:

`nostr-proto`

See nostr-proto for protobuf definitions of core nostr concepts used throughout most modules (e.g. events, filters, etc.).

message Event {
  bytes id = 1 [json_name = "id"];
  bytes pubkey = 2 [json_name = "pubkey"];
  uint64 created_at = 3 [json_name = "created_at"];
  uint32 kind = 4 [json_name = "kind"];
  repeated TagValue tags = 5 [json_name = "tags"];
  string content = 6 [json_name = "content"];
  bytes sig = 7 [json_name = "sig"];
}
