# [nostr-rs-relay](https://git.sr.ht/~gheartsfield/nostr-rs-relay)
|
|
|
|
This is a [nostr](https://github.com/nostr-protocol/nostr) relay,
|
|
written in Rust. It currently supports the entire relay protocol, and
|
|
persists data with SQLite. There is experimental support for
|
|
Postgresql.
|
|
|
|
The project master repository is available on
|
|
[sourcehut](https://sr.ht/~gheartsfield/nostr-rs-relay/), and is
|
|
mirrored on [GitHub](https://github.com/scsibug/nostr-rs-relay).

## 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).
|
|
|
|
The examples below start a rootless podman container, mapping a local
|
|
data directory and config file.
|
|
|
|
```console
|
|
$ podman build --pull -t nostr-rs-relay .
|
|
|
|
$ mkdir data
|
|
|
|
$ podman unshare chown 100:100 data
|
|
|
|
$ podman run -it --rm -p 7000:8080 \
|
|
--user=100:100 \
|
|
-v $(pwd)/data:/usr/src/app/db:Z \
|
|
-v $(pwd)/config.toml:/usr/src/app/config.toml:ro,Z \
|
|
--name nostr-relay nostr-rs-relay:latest

```
|
|
|
|
Use a `nostr` client such as
|
|
[`noscl`](https://github.com/fiatjaf/noscl) to publish and query
|
|
events.
|
|
|
|
```console
|
|
$ 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
|
|
|
|
## Build and Run (without Docker)
|
|
|
|
Building `nostr-rs-relay` requires an installation of Cargo & Rust: https://www.rust-lang.org/tools/install
|
|
|
|
The following OS packages will be helpful; on Debian/Ubuntu:
|
|
```console
|
|
$ sudo apt-get install build-essential cmake protobuf-compiler pkg-config libssl-dev
|
|
```
|
|
|
|
On OpenBSD:
|
|
```console
|
|
$ doas pkg_add rust protobuf
|
|
```
|
|
|
|
Clone this repository, and then build a release version of the relay:
|
|
|
|
```console
|
|
$ git clone -q https://git.sr.ht/\~gheartsfield/nostr-rs-relay
|
|
$ cd nostr-rs-relay
|
|
$ cargo build -q -r
|
|
```
|
|
|
|
The relay executable is now located in
|
|
`target/release/nostr-rs-relay`. In order to run it with logging
|
|
enabled, execute it with the `RUST_LOG` variable set:
|
|
|
|
```console
|
|
$ RUST_LOG=warn,nostr_rs_relay=info ./target/release/nostr-rs-relay
|
|
Dec 26 10:31:56.455 INFO nostr_rs_relay: Starting up from main
|
|
Dec 26 10:31:56.464 INFO nostr_rs_relay::server: listening on: 0.0.0.0:8080
|
|
Dec 26 10:31:56.466 INFO nostr_rs_relay::server: db writer created
|
|
Dec 26 10:31:56.466 INFO nostr_rs_relay::db: Built a connection pool "event writer" (min=1, max=2)
|
|
Dec 26 10:31:56.466 INFO nostr_rs_relay::db: opened database "./nostr.db" for writing
|
|
Dec 26 10:31:56.466 INFO nostr_rs_relay::schema: DB version = 11
|
|
Dec 26 10:31:56.467 INFO nostr_rs_relay::db: Built a connection pool "maintenance writer" (min=1, max=2)
|
|
Dec 26 10:31:56.467 INFO nostr_rs_relay::server: control message listener started
|
|
Dec 26 10:31:56.468 INFO nostr_rs_relay::db: Built a connection pool "client query" (min=4, max=8)
|
|
```
|
|
|
|
You now have a running relay, on port `8080`. Use a `nostr` client or
|
|
`websocat` to connect and send/query for events.
|
|
|
|
## Configuration
|
|
|
|
The sample [`config.toml`](config.toml) file demonstrates the
|
|
configuration available to the relay. This file is optional, but may
|
|
be mounted into a docker container like so:
|
|
|
|
```console
|
|
$ 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 \
|
|
--mount src=$(pwd)/index.html,target=/usr/src/app/index.html,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](docs/reverse-proxy.md).
