Use

Install Rust first.

Gun server

cargo install gundb
gundb start

Gun library

use gundb::{Node, NodeConfig};
use gundb::types::GunValue;
let mut db = Node::new_with_config(NodeConfig {
    outgoing_websocket_peers: vec!["wss://some-server-to-sync.with/gun".to_string()],
    ..NodeConfig::default()
});
let sub = db.get("greeting").on();
db.get("greeting").put("Hello World!".into());
if let Ok(value) = sub.recv().await {
    if let GunValue::Text(str) = value {
        assert_eq!(&str, "Hello World!");
    }
}

Status

3/12/2021:

• Gun basic API
• CLI for running the server
• Incoming websockets
• Outgoing websockets (env PEERS=wss://some-server-url.herokuapp.com/gun)
• Multicast (Iris messages seem not to propagate — size limit?)
• In-memory storage
• TLS support (env CERT_PATH and KEY_PATH)
• Disk storage
• SEA
• Advanced deduplication
