A nostr relay

i'm changing the code a lot in a backwards incompatible way ... this probably isn't ready for prod yet until it has defenses either

• supports many NIPs: 1, 2, 4, 9, 11, 12, 15, 16, 20, 26, 28, 33, 40
• suitable for horizontally scaling websocket layer with a load balancer

• defend itself: no rate limits, spam prevention, payments
  • i'd like to provide these via some plugin mechanism (workers, maybe?)
• use postgres read replicas

• deno serves websockets
• filters are stored in a sqlite in memory database and mapped to a websocket
• events are persisted in postgres
• when an event is persisted (or an ephemeral event is received) a postgres NOTIFY event, <event json> is broadcast
• all booger processes in the cluster LISTEN event and when notified check sqlite for matching filters and send to corresponding websockets

0. install postgres and run it (welcome to app programming)
1. insall deno (welcome to deno)
2. clone booger
3. configure env in .env.defaults
4. deno task dev

simplicity, ease of use, extensibility, scalability, performance, security

1. camari's nostream - heavily inspired booger's validation and integration tests
2. everyone working on nostr
3. my cat dona, meow
