nostr-rs-relay

This is a nostr relay, written in Rust. It currently supports the entire relay protocol, and has a SQLite persistence layer.

The project master repository is available on sourcehut, and is mirrored on GitHub.

Features

NIPs with a relay-specific implementation are listed here.

• NIP-01: Basic protocol flow description
  • Core event model
  • Hide old metadata events
  • Id/Author prefix search
• NIP-02: Contact List and Petnames
• NIP-03: OpenTimestamps Attestations for Events
• NIP-05: Mapping Nostr keys to DNS-based internet identifiers
• NIP-09: Event Deletion
• NIP-11: Relay Information Document
• NIP-12: Generic Tag Queries
• NIP-15: End of Stored Events Notice
• NIP-16: Event Treatment
• NIP-22: Event created_at limits (future-dated events only)
• NIP-26: Event Delegation

Quick Start

The provided Dockerfile will compile and build the server application. Use a bind mount to store the SQLite database outside of the container image, and map the container's 8080 port to a host port (7000 in the example below).

$ docker build -t nostr-rs-relay .

$ docker run -it -p 7000:8080 \
  --mount src=$(pwd)/data,target=/usr/src/app/db,type=bind nostr-rs-relay

[2021-12-31T19:58:31Z INFO  nostr_rs_relay] listening on: 0.0.0.0:8080
[2021-12-31T19:58:31Z INFO  nostr_rs_relay::db] opened database "/usr/src/app/db/nostr.db" for writing
[2021-12-31T19:58:31Z INFO  nostr_rs_relay::db] DB version = 2

Use a nostr client such as noscl to publish and query events.

$ noscl publish "hello world"
Sent to 'ws://localhost:8090'.
Seen it on 'ws://localhost:8090'.
$ noscl home
Text Note [81cf...2652] from 296a...9b92 5 seconds ago
  hello world

A pre-built container is also available on DockerHub: https://hub.docker.com/r/scsibug/nostr-rs-relay

Configuration

The sample config.toml file demonstrates the configuration available to the relay. This file is optional, but may be mounted into a docker container like so:

$ docker run -it -p 7000:8080 \
  --mount src=$(pwd)/config.toml,target=/usr/src/app/config.toml,type=bind \
  --mount src=$(pwd)/data,target=/usr/src/app/db,type=bind \
  nostr-rs-relay

Options include rate-limiting, event size limits, and network address settings.

Reverse Proxy Configuration

For examples of putting the relay behind a reverse proxy (for TLS termination, load balancing, and other features), see Reverse Proxy.
