# gnost-relay
Nostr relay written in go
## Features
- NIPs supported: [1][1], [9][9], [11][11], [12][12], [15][15], [16][16], [20][20], [26][26], [28][28], [33][33], [40][40], [42][42].
- Websocket compression support (`permessage-deflate`), with support for client and server context takeover (i.e., sliding window support).
- Hot config reloading. Edits to the `config.json` file will be instantly applied without requiring restart.
- `--import` command line flag allows new events to be added via `stdin`. Events should be in `jsonl` format. Use in conjunction with [gnost-deflate-client][gnost-deflate-client]
- Event handling logic happens via SQL triggers (i.e., NIPs [9][9], [16][16], [33][33], [40][40]).
- New events are notified to listeners via postgresql's built in `pg_notify` feature. This implies that different instances of `gnost-relay` can be run concurrently. Indeed, any software which writes to the DB will automatically notify listeners connected to the relay.
- Memory allocations are minimized using pools.
- Token bucket style rate limiters for handling the messages are enabled on each websocket connection.
## Example usage
#### Running the relay
```zsh
DATABASE_URL=postgres://x gnost-relay --config config.json
```
#### Importing events
With `keepalive` set, the connection will remain open, and new events will be added to the `gnost-relay` database, and notified to any listeners. See [gnost-deflate-client][gnost-deflate-client] for more info.
```zsh
echo '[{"since":1676863922,"kinds":[1]}]' |\
gnost-deflate-client --port 443 --scheme wss --host nos.lol --keepalive 30 --output - |\
DATABASE_URL=postgres://x gnost-relay --import
```

## Installation notes
- Needs to have a `postgresql` database configured. The executable expects that the `DATABASE_URL` environment variable is set.
- Should be run with a reverse proxy in front (e.g., NGINX).
- See the [instructions](INSTALL.md) for more details.
